I have a database table that has two columns eventName|eventDate. I have created a function that takes in a startDate and endDate, I want to display the list of events in a ListView with each date as the header.
In my brief example below, I know I can retrieve the full event listings with SQL. How do I then slot the event headers in so that I can return them in a properly formatted array?
function retrieveEvents($startDate, $endDate) {
// run SQL query
//
if($stmt->rowCount() > 0) {
while($row = $stmt->fetch(PDO::FETCH_ASSOC)) {
// how do I write this part such that I can output event headers in my array
$events = $row;
}
}
}
So my intended output is
1st July 2013 ($startDate)
- Tea with President - 1300h
- Mow the lawn - 1330h
- Shave the cat - 1440h
2nd July 2013
- Shave my head - 0800h
3rd July 2013
4th July 2013 ($endDate)
- Polish the car - 1000h
In your MYSQL query:
SELECT * FROM `yourTableName` WHERE `eventDate` >= $startDate AND `eventDate` <= $endDate
PS: I'm not sure about the quotes arount the variables in your query.
PPS: never use * to select your columns, always only select the columns you need. Here I'm using it because I don't know the names of your columns
I ended up doing my checking in PHP and print a new row only when a different date is detected.
Codes below in case it serves someone's needs in future.
<?php
$currentPrintDay = 0;
$currentPrintMonth = 0;
$currentPrintYear = 0;
echo "<table>"
foreach($reservationsToShow as $row):
// get day, month, year of this entry
$timestamp = strtotime($row['timestamp']);
$day = date('d', $timestamp);
$month = date('m', $timestamp);
$year = date('Y', $timestamp);
// if it does not match the current printing date, assign it to the current printing date,
// assign it, print a new row as the header before continuing
if($day != $currentPrintDay || $month != $currentPrintMonth || $year != $currentPrintYear) {
$currentPrintDay = $day;
$currentPrintMonth = $month;
$currentPrintYear = $year;
echo
"<tr>" .
"<td colspan='100%'>". date('d-m-Y', $timestamp) . "</td>" .
"</tr>";
}
// continue to print event details from here on...
?>

Adding days to $Date in PHP
(12 answers)
Closed 5 years ago.
I have a table in MySQL with a date field (called NDate) which contains standard date values ("2017-04-17","2017-04-18", etc.).
Through PHP webpage, I am trying to take the system date (say today is 2017-04-17), and then pull all rows from the above table where NDate="2017-04-17". No issues till here.
I have a requirement to increment the day (starting today and going on for next 10 days - i.e. 2017-04-17 to 2017-04-26), and for each day report entries under a different heading like "Entries for 2017-04-17" which will list all rows having NDate 2017-04-17, "Entries for 2017-04-18" which will list all rows having NDate 2017-04-18.
I was trying to use a for loop with PHP date_modify function to increment the days one by one, but it is not showing any results.
Here are the selected pieces of code:
date_default_timezone_set('US/Eastern');
$datev = date("Y-m-d");
for ($x = 0; $x <= 10; $x++)
{
$datev=date_modify($date,"+$x days");
echo "before date format<br>"; // echo statement 1
echo "date is: $datev <br>"; // echo statement 2
$sql = "SELECT * FROM tablename where Ndate='$datev'";
echo "before result<br>"; // echo statement 3
...
...
...
}
Output on webpage shows only statement 1. But echo stats 2 and 3 are not printed.
You can increment days using strtotime function as a parameter to date function.
For 10 days, you can use for loop, to build an array of days. Then iterate over it, to execute queries you need.
$today = date('Y-m-d');
$dates=array($today);
for($i=1;$i<10;$i++) {
$NewDate=date('Y-m-d', strtotime("+".$i." days"));
$dates[]=$NewDate;
}
foreach($dates as $dt) {
// sql stuff here
echo "date is: $dt <br>";
$sql = "SELECT * FROM tablename where Ndate='$dt'";
echo "before result<br>";
// .....
}
This code should work for your case. If any problems, just let me know.
Try this:
$start = strtotime(date('Y-m-d'));
$end = strtotime(date('Y-m-d', strtotime('+10 days')));
while($start <= $end)
{
$date = date('Y-m-d', $start);
//use $date to do stuff
//SELECT * FROM tablename where Ndate='$date'
$start = strtotime("+1 day", $start);
}
How I can convert INT to date in php and than find this date in mysql table ?
Lets say I want to convert
$month = (int)$_GET['month'];
$month = 42014 ;//This means 04th month in 2014 year
$month = 04-2014; // I want this
And than find that in mysql table
$query=mysql_query("SELECT id FROM matches WHERE date=$month");// This need to select
// all data that is
// created in 04th month
// of 2014 year .
echo "Thanks :)";
Don't pass $month parameter like you do.
Send and pass both $month and $year and handle them after:
$month = (int)$_GET['month'];
$year = (int)$_GET['year'];
if($month < 10) { // add this check for months lesser then october (they containt 1 digit, which is wrong for t-sql)
$month = "0".$month;
}
$query=mysql_query("SELECT id FROM matches WHERE DATE_FORMAT(datefield, '%m-%Y') = '$month-$year'");
source
If you can't send both month and year in different variables, do this, like M Khalid Junaid suggested:
$query=mysql_query("SELECT id FROM matches WHERE DATE_FORMAT(datefield,'%m%Y')='$month'");
Try as below using DateTime::createFromFormat
$month = $_GET['month'];
$date = DateTime::createFromFormat('mY',$month);
echo $date->format('m-Y');
Try this
$input=42014;
$year = strlen(substr($input,-4));
$month = substr(0,(strlen($input)-strlen($year)));
$final = $month."-".$year
I am trying to write a script to pull dates for the next 7 days and put them into a div for each date :
echo '<div class="dateboxcontainer">';
for($i=0; $i<=6; $i++){
echo '<div class="datebox"><div class="topdate">'.strtoupper(date("D d", mktime(0, 0, 0, 0, date("d")+$i, 0))."\n").
'</div><div class="bottomdate">An appointment for the day</div></div>';
}
echo '</div>';
Im now trying to pull data from my database from two fields 'datedroppingoff' and 'datepickingup', which are formatted like this '2013-07-10 14:29:28'.
Im kind of stuck though as im not sure what query to write to put the appointments for each day into each day div where 'some info' currently sits.
Im guessing it would be something like
Select * FROM jobdetails WHERE datedroppingoff OR datepickingup = WHATEVER DAY IS BEING ECHO'D OUT
but im not quite sure how I can compare the date stored in jobdetails for that row to the date being echo'd out ?.
Edit>>>>>
Thanks for the answers below, iv managed to come up with the following, it echos out the date boxes ok, but doesnt bring in any data, so im not sure if I have the sql part correct ?.
echo '<div class="dateboxcontainer">';
$eventdata = <<<SQL
SELECT *
FROM `jobdetails`
SQL;
if(!$events = $db->query($eventdata)){
die('There was an error running the query [' . $db->error . ']');
}
// read first event
if ($nextEvent = mysql_fetch_assoc($events)) { // here is the first one
extract($nextEvent); // prepare its variables
// use the event date it to control the inner loop
$nextDate = $datedroppingoff;
} else // no events?
$nextDate = 0; // prepare a fake date value
// calculate today date
$currentDate = mktime();
// loop on the dates for the next 7 days
for ($i = 0 ; $i < 7; $i++) {
$currentEvents = "";
// loop to print every event for current day (first one already extracted)
while ($nextDate == date("Y-m-d", $currentDate)) { // next event occurs today
// here prepare the var containing the event description
// BTW, I'd use a list for the events
$currentEvents .= "· $name<br>"; // use every field you need from current DB row
// read next event
if ($nextEvent = mysql_fetch_assoc($events)) { // here is the next one
extract($nextEvent); // prepare its variables
// use the event date it to control the inner loop
$nextDate = $datedroppingoff;
} else // no more events?
$nextDate = 0; // prepare a fake date value
}
echo "
<div class='datebox'>
<div class='topdate'>" . strtoupper(date("D d m Y", $currentDate)) . "</div>
<div class='bottomdate'>$currentEvents</div>
</div>";
$currentDate = strtotime("+1 day", $currentDate);
}
echo '</div>';
Can you use something like this:
SELECT * FROM `jobdetails` WHERE (`datedroppingoff ` > '2013-07-01 00:00:00' AND `datedroppingoff ` '2013-07-02 00:00:00') OR (`datepickingup ` > '2013-07-01 00:00:00' AND `datepickingup ` '2013-07-02 00:00:00');
This will have to be repeated per day (i.e. for each of the 5 days)
To do a nice loop, use an array populated with the next 5 dates as strings. Then do a foreach over the dates and run this query.
If you want all dates from now and for the next 5 days, you could use:
WHERE
`datedroppingoff` BETWEEN NOW() AND DATE_ADD(NOW(), INTERVAL 5 DAY) OR
`datepickingup ` BETWEEN NOW() AND DATE_ADD(NOW(), INTERVAL 5 DAY)
Let's see how I'd proceed (by the way, this is my first answer, so I'm a little excited...)
First, some basic assumptions for this ultra-fast script (sorry, not so much time now to test it thoroughly).
your Appointment table has a field with the date of the appointment
your result resource ($events) contains only the rows for the current week
the resulting rows are sorted by the date field, ascending (from oldest to newest)
Try this (I've changed a bit your original code, sorry)
// read first event
if ($nextEvent = mysql_fetch_assoc($events)) { // here is the first one
extract($nextEvent); // prepare its variables
// use the event date it to control the inner loop
$nextDate = $DB_field_with_event_date;
} else // no events?
$nextDate = 0; // prepare a fake date value
// calculate today date
$currentDate = mktime();
// loop on the dates for the next 7 days
for ($i = 0 ; $i < 7; $i++) {
$currentEvents = "";
// loop to print every event for current day (first one already extracted)
while ($nextDate == date("Y-m-d", $currentDate)) { // next event occurs today
// here prepare the var containing the event description
// BTW, I'd use a list for the events
$currentEvents .= "· $your_desc_field<br>"; // use every field you need from current DB row
// read next event
if ($nextEvent = mysql_fetch_assoc($events)) { // here is the next one
extract($nextEvent); // prepare its variables
// use the event date it to control the inner loop
$nextDate = $DB_field_with_event_date;
} else // no more events?
$nextDate = 0; // prepare a fake date value
}
echo "
<div class='datebox'>
<div class='topdate'>" . strtoupper(date("D d m Y", $currentDate)) . "</div>
<div class='bottomdate'>$currentEvents</div>
</div>";
$currentDate = strtotime("+1 day", $currentDate);
}
Tried a couple of times on fake data and it should work. IMHO better to directly alias the date field to get the nextDate var directly from the DB, so avoiding the rows,
$nextDate = $DB_field_with_event_date;
I used this in the end which seems to do the job ! :)
// Date box container
echo '<div class="dateboxcontainer">';
// Loop through and create a date for the next 7 days
$days = new DatePeriod(new DateTime, new DateInterval('P1D'), 7);
foreach ($days as $day) {
echo '<div class="datebox">';
echo '<div class="topdate">';
echo strtoupper($day->format('D d')) . PHP_EOL;
echo '</div>';
// Get the names for each day
$theday = strtoupper($day->format('Y-m-d'));
$sqldate = <<<SQL
SELECT *
FROM `jobdetails`
WHERE datedroppingoff = '$theday' OR datepickingup = '$theday'
SQL;
if(!$resultdate = $db->query($sqldate)){
die('There was an error running the query [' . $db->error . ']');
}
while($rowdate = $resultdate->fetch_assoc()){
echo $rowdate['name'];
}
//
echo '</div>';
}
echo '</div>';

I have got strange issue with dates of events and I have tried hard to get it fixed but unable to do it.
I am attaching a screenshot of how I want to display the dates on the page :
In the picture the first event Deine Energie in Aktion! is a combination of 5 events with each event having its start date and end date.
The first part of the event is 1 day event which starts on 4th April and ends on 4th April. Similarly the second part is on 7th April, 3rd part on 9th April and 4th part on 20th April
The last part starts on 5th May and ends on 10th May.
The dates are stored in database in this format :
I am showing the dates for last part of event.
Event Start Date : 2013-05-05 00:00:00
Event End Date : 2013-05-10 00:00:00
So I want to display dates in the format shown in the picture.
There are multiple cases:
First is if all the dates are coming within a single month then we display the month name at the end only once.
Second is if months are changed then the month name will be shown after the date when the month is changed.
I am getting events dates in a while loop, so how do I compare the current event date with the coming event date in a loop.
This is the code I have used so far to get the dates from the database..
$nid = $row->nid;
$get_product_id = "SELECT product_id from {uc_product_kits} where nid='$nid'";
$res = db_query($get_product_id);
while ($get_product_id_array_value = db_fetch_array($res)) {
$prductid = $get_product_id_array_value['product_id'];
$start_date = db_query("select event_start,event_end from {event} where nid=%d",$prductid);
$start_date_value = db_fetch_object($start_date);
$end_value = $start_date_value->event_start;
$event_end_date = $start_date_value->event_end;
$TotalStart = date("d M Y", strtotime($end_value));
$TotalEnd = date("d M Y", strtotime($event_end_date));
$onlyMonthStart = date("M", strtotime($end_value));
$onlyMonthEnd = date("M", strtotime($event_end_date));
//$groupMonth = db_query("select event_start,event_end, month from {event} where nid=%d group by ",$prductid);
if($TotalStart == $TotalEnd ){
$startDay = date("d", strtotime($end_value));
$startMonth = date("M", strtotime($end_value));
if(in_array($startMonth,$newMonth)) {
echo $onlstartdate;
}
else {
$onlstartdate = date("d", strtotime($end_value));
echo $onlstartdate;
$tempStorage[] = $startMonth
}
//$newMonth[] = $startMonth;
}
}
Easiest would be to first collect all data from your query into e.g. array.
Only then iterate over the array. Having all data together will allow you to compare two consecutive date ranges to decide level of details you need to print for each.
Commented example:
// collect data from SQL query into structure like this:
$events = array(
array("event_start" => "2013-4-4", "event_end" => "2013-4-4"),
array("event_start" => "2013-4-7", "event_end" => "2013-4-7"),
array("event_start" => "2013-4-9", "event_end" => "2013-4-9"),
array("event_start" => "2013-4-20", "event_end" => "2013-4-20"),
array("event_start" => "2013-5-5", "event_end" => "2013-5-10"),
array("event_start" => "2014-1-1", "event_end" => "2014-1-2"),
);
// the actual code for range list generation:
for ($i = 0; $i < count($events); $i++)
{
// parse start and end of this range
$this_event = $events[$i];
$this_start_date = strtotime($this_event["event_start"]);
$this_end_date = strtotime($this_event["event_end"]);
// extract months and years
$this_start_month = date("M", $this_start_date);
$this_end_month = date("M", $this_end_date);
$this_start_year = date("Y", $this_start_date);
$this_end_year = date("Y", $this_end_date);
$last = ($i == count($events) - 1);
// parse start and end of next range, if any
if (!$last)
{
$next_event = $events[$i + 1];
$next_start_date = strtotime($next_event["event_start"]);
$next_end_date = strtotime($next_event["event_end"]);
$next_start_month = date("M", $next_start_date);
$next_end_month = date("M", $next_end_date);
$next_start_year = date("Y", $next_start_date);
$next_end_year = date("Y", $next_end_date);
}
// ranges with different starting and ending months always go
// on their own line
if (($this_start_month != $this_end_month) ||
($this_start_year != $this_end_year))
{
echo date("j M", $this_start_date);
// print starting year only if it differs from ending year
if ($this_start_year != $this_end_year)
{
echo " ".date("Y", $this_start_date);
}
echo "-".date("j M Y", $this_end_year)." <br/>\n";
}
else
{
// this is range starting and ending in the same month
echo date("j", $this_start_date);
// different starting and ending day
if ($this_start_date != $this_end_date)
{
echo "-".date("j", $this_end_date);
}
$newline = false;
// print month for the last range;
// and for any range that starts(=ends) in different month
// than the next range ends
if ($last ||
($this_start_month != $next_end_month))
{
echo " ".date("M", $this_start_date);
$newline = true;
}
// print year for the last range;
// and for any range that starts(=ends) in different year
// than next range ends
if ($last ||
($this_start_year != $next_end_year) ||
($next_start_month != $next_end_month))
{
echo " ".date("Y", $this_start_date);
$newline = true;
}
if ($newline)
{
echo " <br/>\n";
}
else
{
// month (and year) will be printed for some future range
// on the same line
echo ", ";
}
}
}
This outputs:
4, 7, 9, 20 Apr <br/>
5-10 May 2013 <br/>
1-2 Jan 2014 <br/>
A possibility to check if you need to print the month for the current date item is actually to check in the next item. Let me try to explain with pseudocode:
<?php
$month = 0; // Initialize $month variable to unset
// Loop over all your events
foreach($dates as $date) {
// Convert $date to a timestamp
// If the 'month' of the current $timestamp is unequal to $month
// it means we switch months and we have to print the $month first
if(date('m', $timestamp) != $month) {
echo $month; // Of course format how you want it to be displayed
// Set $month to the new month
$month = date('m', $timestamp);
}
// Print the rest of the event, like day numbers here
}
?>
Well, since you need to compare value from one loop to another, you won't be able to use echo directly.
You need to use temp variables. So with the first loop for the start date, you store $tmp_day_1 and $tmp_month_1 then with the end date loop you can compare both months and check if they are diferents. Then you can use echo. I hope I make my point :)
I'm creating a TV Guide which lists programmes coming up (and on some listings, previous airings from the past), with all data stored in a database. It runs in PHP, my version being 5.28 (upgrading to 5.30 or 6 soon).
Below is a script which works (note the field airdate is stored as DATETIME in the database):
[Disclaimer: The script isn't mine, but a generic one I downloaded, and modified to suit my own needs.]
<? //connect to mysql //change user and password to your mySQL name and password
mysql_connect("localhost","root","PASSWORD");
//select which database you want to edit
mysql_select_db("tvguide1");
//select the table
$result = mysql_query("select * from epdata3 order by airdate LIMIT 20;");
//grab all the content
while($r=mysql_fetch_array($result))
{
//the format is $variable = $r["nameofmysqlcolumn"];
//modify these to match your mysql table columns
$programme=$r["programme"];
$channel=$r["channel"];
#$airdate = strtotime($r['airdate']);
$airdate = strtotime($r['airdate']);
$now = strtotime("NOW");
$currentYear = date("Y", $now);
$yearOfDateFromDatabase = date("Y", $airdate);
if($yearOfDateFromDatabase == $currentYear)
$dateFormat = "F jS - g:ia"; // dateFormat = 24 December
else
$dateFormat = "F jS, Y - g:ia"; // dateFormat = 01 January 2010
$currentTime = date("g:ia", $airdate); // format of "Y" gives four digit year ie
2009 not 09
$airdateFormatted = date($dateFormat, $airdate);
$sDate = date("F dS, Y - g:ia",$airdate);
$episode=$r["episode"];
$setreminder=$r["setreminder"];
echo "<tr><td><b>$programme</b></td><td>showing on $channel</td>";
echo "<td>$airdateFormatted</td><td>$episode</td><td>$setreminder</td></tr>";
}
?>
That displays all the episodes coming up, and if there's any coming up the next year, it displays them with the year, like this:
TV Programme showing next on Channel1 December 30th, 2009 - 6:00pm "Episode 1 - Photosynthesis" Set Reminder
TV Programme showing next on Channel1 January 6th - 2:45pm "Episode 2 - Behind the Music" Set Reminder
TV Programme showing next on Channel1 January 7th - 8:00pm "Ultimate Car Crimes" Set Reminder
However, what I would like it to do is remove certain records after a period of time has expired (but that would have to be set somewhere in the script, since programme lengths vary) rather than me manually deleting them from the database. Some programmes are 30 minutes long, others 60 minutes... lengths vary, basically.
What I would like it to do is this (notice that the first listing does not show the date as it is the current date.):
TV Programme showing next on Channel1 6:00pm "CCTV Cities - Wigan" Set Reminder
TV Programme showing next on Channel1 January 9th - 2:45pm "Roman Empire - A History of its People" Set Reminder
TV Programme showing next on Channel1 January 10th - 8:00pm "Celebrity 100 Worst Moments" Set Reminder
but I don't know how to configure it to do this with PHP or the date() function. It works fine with the dates, and showing them.
I don't have access to cron jobs since this is on a localhost Apache installation on Windows Vista Home Edition.
If anyone could help me figure this out it would be much appreciated - all help is much appreciated.
I haven't put this as a live site, since it's "in development hell" right now, and I want to get things right as much as possible.
Your question is a bit unclear, but I assume you are asking how you can select only episodes from today or future, and how to format the date so that when the episode is airing today, show only the date.
Here's a revised version of your code that can handle both of those:
<?php
//connect to mysql
mysql_connect("localhost","root","PASSWORD");
mysql_select_db("tvguide1");
// Select only results for today and future
$result = mysql_query("SELECT * FROM epdata3 WHERE airdate >= CURDATE() ORDER BY airdate ASC LIMIT 20;");
while($r = mysql_fetch_array($result)) {
$programme = $r["programme"];
$channel = $r["channel"];
$airdate = strtotime($r['airdate']);
$episode = $r["episode"];
$setreminder = $r["setreminder"];
$now = time();
if(date('Y-m-d') == date('Y-m-d', $airdate)) {
// Same date, show only time
$dateFormat = 'g:ia';
} elseif(date('Y') == date('Y', $airdate)) {
// Same year, show date without year
$dateFormat = 'F jS - g:ia';
} else {
// Other cases, show full date
$dateFormat = 'F jS, Y - g:ia';
}
$airdateFormatted = date($dateFormat, $airdate);
echo "<tr><td><b>$programme</b></td><td>showing on $channel</td>";
echo "<td>$airdateFormatted</td><td>$episode</td><td>$setreminder</td></tr>";
}
?>
MySQL can literally handle millions of records - why bother deleting when you can archive..? Just don't show the archived records.
for listing future records instead of this:
$result = mysql_query("select * from epdata3 order by airdate LIMIT 20;");
I would suggest something like this:
$result = mysql_query("select * from epdata3 WHERE airdate > '$today' ORDER BY airdate LIMIT 20;");
For a gig listing page I years ago also added a delete algorythm fearing the db could get 'full' - but regretted it later...
function reldate ($time) {
$now = time();
$cmp_fmt = '%Y%m%d';
if (strftime($cmp_fmt, $time) == strftime($cmp_fmt, $now)) {
$out_fmt = '%I:%M %P';
} else {
$day = strftime('%e', $time);
if (preg_match('/([^1]1|^1)$/', $day)) {
$day_suffix = 'st';
} elseif (preg_match('/([^1]2|^2)$/', $day)) {
$day_suffix = 'nd';
} elseif (preg_match('/([^1]3|^3)$/', $day)) {
$day_suffix = 'rd';
} else {
$day_suffix = 'th';
}
$out_fmt = '%B %e' . $day_suffix . ' - %I:%M %P';
}
return strftime($out_fmt, $time);
}
