I've been trying many different ways to pass the dates into the query as a variable, and nothing I've tried has worked. When I put the exact dates in there like below, the query works fine.
$ly = mysqli_query($link,'SELECT SUM(rtype_price) FROM client WHERE date BETWEEN "2017-01-01" AND "2017-12-31"');
while($row1 = mysqli_fetch_array($ly))
{
$ly_cash = $row1['SUM(rtype_price)'];
}
For example, I've been trying something like this:
$ly_start = date('Y-m-d', strtotime('first day of previous year'));
$ly_end = date('Y-m-d', strtotime('last day of previous year'));
then passing $ly_start and $ly_end into the query like this:
$ly = mysqli_query($link,'SELECT SUM(rtype_price) FROM client WHERE date BETWEEN "$ly_start" AND "$ly_end"');
Inverting the quotes did the trick. This works:
$ly = mysqli_query($link,"SELECT SUM(rtype_price) FROM client WHERE paid = 1 AND date BETWEEN '$ly_start' AND '$ly_end'");
while($row1 = mysqli_fetch_array($ly))
{
$ly_cash = $row1['SUM(rtype_price)'];
}
Thank you ild_flue

So I am working on a simple website and I ran into a problem. I have a subscription based website and I have a date expired for when their subscription ends. This all works well, but when I tried to display the expiration date I ran into problems. The first 3 lines are what i have been trying. It seems as if the timestamp isnt correctly being transferred from the database because when I did my test at the button, this displayed the correct date. The top 3 lines always give me this: 1970/01/01
// Get Expiration Date
// Always gives me 1970/01/01
$datexpire = "SELECT date-expire FROM users WHERE username='{$_SESSION['username']}'";
$timestamp = mysqli_query($link, $datexpire);
$date = date("Y/m/d",$timestamp);
//This works
$timestamp2 = 1537847863;
$date2 = date("Y/m/d",$timestamp2);
If anyone could help that would be much appreciated
i think your code should be something like
$datexpire = "SELECT date-expire FROM users WHERE username='{$_SESSION['username']}'";
$result = mysqli_query($link, $datexpire);
$row=mysqli_fetch_assoc($result));
$timestamp = $row['date_expire'];
$date = date("Y/m/d", $timestamp);
echo $date;
please check for column name.. if it is date-expire or date_expire ??? (dash or underscore ??)
mysqli_query returns a mysqli_result object or a boolean value.
You want to fetch a row from your given object, like so:
$datexpire = "SELECT `date-expire` FROM users WHERE username='{$_SESSION['username']}'";
$result = mysqli_query($link, $datexpire);
$row = mysqli_fetch_assoc($result);
$date = date("Y/m/d", $row["date-expire"]);
I am building a script to display some 24 hour charts. I am attempting to make 12 charts. One 24 hour (last hour) chart for each five minute data set i have collected. I am running accross an issue where my mysql command will not update the $hour_position. I've read many while loop inside while loop questions and have tried to construct a foreach alternative, and also tried to reset the query array, but none of this has worked. Any comments or links to another thread that can solve this problem would be appreciated.
Thanks in advance.
$hour_position = 00;
$htime = -1;
$date = date('Y-m-d H:i:s');
$date = strtotime($date);
$date = strtotime($htime." day", $date);
$date = date('Y-m-d H:i:s',$date);
while($hour_position < 60){
$price_history_qry = mysqli_query($con,"SELECT * FROM `dbTable` WHERE `server_time` > '$date' AND EXTRACT(MINUTE FROM `server_time`) like $hour_position ORDER BY `server_time` ASC");
while($result = mysqli_fetch_array($price_history_qry)){
//Create a couple of arrays to build a chart.
}
//Build chart here
echo $chart;
$hour_position = $hour_position +05;
}
Try putting $hour_position in quote like
' $hour_position '
or you can use
". $hour_position ."
Your query has a small mistake. The variable inside single quotes will not be evaluated as variable. Check this. you need to change the select query like below.
$price_history_qry = mysqli_query($con,"SELECT * FROM `dbTable` WHERE `server_time` > '".$date."' AND EXTRACT(MINUTE FROM `server_time`) like ".$hour_position." ORDER BY `server_time` ASC");
And i haven't find any update query in your code. As you said you are using the update query inside while loop. So first check whether the variable has the value and then check whether it entering to while loop like below.
$result = mysqli_fetch_array($price_history_qry)
var_dump($result);
while($result){
//Create a couple of arrays to build a chart.
var_dump("entered");
}
Try to use var_dump() function to debug.
Hope it helps you.
When I retrieve a date from a my_sqli query and format it it becomes one day forward. The date is saving correctly to the server, and echoing it before the new format is correct.
$date = "SELECT date FROM blogtable WHERE id = $artID";
$dateEx = mysqli_query($con, $date);
while($dateGet = mysqli_fetch_array($dateEx))
{
//This is in YYYY-mm-dd
$dateGet['date'];//If I echo this, it is correct
}
$source = $dateGet;
$newDate = new DateTime($source);
echo $newDate->format('M-d-Y');
So for example if I tried to use it today(the 24th), it would save correctly, but after the format, display as the 25th.
Wrikken's suggestion worked, changing the statement in the while to $source=$dateGet['date']; and deleting the $source = $dateGet;.
I have a problem getting certain data from my database by querying a date range. In my database i have a DATE type field within the format YYYY-MM-DD. I want to get all data within a date range of today + 2 weeks (Expiring).
I have wrote:
$format = 'Y-m-j';
$date = date ( $format );
$new = date ( $format, strtotime ( '+14 day' . $date ) );
$start = date("Y-m-d", strtotime($new));
$today = date('Y-m-d');
$q = "SELECT * FROM listing WHERE dd_end BETWEEN '".$today."' AND '".$start."'";
while($row = mysql_fetch_assoc($q)){
$listing_id = $row['listing_id'];
echo "$listing_id";
}
So what I want to achieve is for the query to pull all the rows from now until 5th October. I've echo'd the variables and they show they're in the correct form (YYYY-MM-DD) to compare within the database but no results are returning.
Any help would be greatly appreciated. Many thanks in return.
Well, assuming that the mysql database has the same date that your server, you could let the mysql database do all the date calculations.
A little something like this:
SELECT *
FROM listing
WHERE dd_end BETWEEN CURDATE() AND (CURDATE() + INTERVAL 14 DAY)
On the other hand, i think Paul S's answer may fix your problem.
Edit:
You forgot to call mysql_query before the mysql_fetch_assoc() function.
$result = mysql_query($q);
while ($row = mysql_fetch_assoc($result))
{
$listing_id = $row['listing_id'];
echo "$listing_id";
}
If dd_end is a date you may want to read a certain section on the MySQL docs: http://dev.mysql.com/doc/refman/5.0/en/comparison-operators.html#operator_between
For best results when using BETWEEN with date or time values, use
CAST() to explicitly convert the values to the desired data type.
Examples: If you compare a DATETIME to two DATE values, convert the
DATE values to DATETIME values. If you use a string constant such as
'2001-1-1' in a comparison to a DATE, cast the string to a DATE.
May this is the right way ?
$start = date("Y-m-d", strtotime('+14 day' . $date));
Read:
http://php.net/manual/en/function.strtotime.php
strtotime has a second argument.
$format = 'Y-m-j';
$date = date ( $format );
$new = date ( $format, strtotime ( '+14 day' . $date ) );
$start = date("Y-m-d", strtotime($new));
Should be:
$new = strtotime('+14 day', time());
$start = date("Y-m-d", $new);
$today = date('Y-m-d');
$q = mysql_query("SELECT * FROM listing WHERE dd_end BETWEEN '".$today."' AND '".$start."'");
while($row = mysql_fetch_assoc($q)){
$listing_id = $row['listing_id'];
echo "$listing_id";
}
All I'm trying to do is make the php file accumulate the end date from the sub date. I don't understand why this strtotime function isn't working. My database stores dates as "Y-m-d".
here's the code:
//disguised for security reasons
$db = mysql_connect("*******", "*******","********");
mysql_select_db("*******",$db);
$getad = mysql_query("SELECT id, annual_sub_date FROM members WHERE annual_sub_date!=null", $db);
while ($gad = mysql_fetch_array($getad)) {
$id = $gad['id'];
$asd = $gad['annual_sub_date'];
$aedate_time = strtotime('+1 year', $asd);
$aedate = date("Y-m-d", $aedate_time);
mysql_query("UPDATE members SET annual_end_date='$aedate', annual_active='Y' WHERE id='$id'");
}
---------SOLVED IT---------
I went and played XBox Split/Second for a bit and then realised the issue. My mind went back to PHP/MySQL 101. I coded everything right except the "!=null" part.
//Wrong Way
$getad = mysql_query("SELECT id, annual_sub_date FROM members WHERE annual_sub_date!=null", $db);
//Correct Way
$getad = mysql_query("SELECT id, annual_sub_date FROM members WHERE annual_sub_date IS NOT NULL", $db);
Now everything works :) That's the issues you can expect coding at 5:01am.
The first argument to strtotime is an absolute or relative date as a string, the second argument is an integer timestamp. You're giving it a relative date (string) as the first argument and an absolute date (also string) as the second. You need to convert $asd to a timestamp using strtotime first.
$aedate_time = strtotime('+1 year', strtotime($asd));
BTW, you could do the whole date calculation and updating in SQL with a single query, no need to take the long way around through PHP.
It's because strtotime requires timestamp as second argument and not string date in Y-m-d.
Just try code snippet below to see what I ment.
$gad = array('annual_sub_date' => '2010-11-21');
// wrong
// $asd = $gad['annual_sub_date'];
// good; convert to timestamp
list($year, $month, $day) = explode('-', $gad['annual_sub_date']);
$asd = mktime(0, 0, 0, $month, $day, $year);
$aedate_time = strtotime('+1 year', $asd);
$aedate = date("Y-m-d", $aedate_time);
echo $aedate . "\n";
