I have two 'includes' php pages, Page 1 and Page 2.
Page 1 displays contents for today, Page 2 displays contents for yesterday.
I set a cronjob to copy contents of Page 1 to Page 2 every 0:00am daily.
On the main page (the page that contains this page 1 and page 2), I have:
$date = date("d/m", strtotime("now"));
$dateyes = date("d/m", strtotime("-1 day"));
Then on Page 1, I have:
echo $date;
On Page 2, what I need is:
echo $dateyes;
But due to the cronjob, I only get
echo $date;
on that Page 2. Is there a way I can change that $date to $dateyes on that Page 2?
Not really sure how copying a php script from day to day should work in practice, but if need this pattern for some reason, simply replace your current echo $date; to echo $is_page1 ? $date : $dateyes;
Where $is_page a variable that check which page is loaded via something like:
$is_page1 = $_SERVER['SCRIPT_NAME'] === 'page1.php';
Or:
$is_page1 = basename(__FILE__) === 'page1.php';
I found a solution.
On the mainpage.php, I checked if "dateyes" already exists in page2.php, if it already exists, script does nothing but if "dateyes" does not exist, my script searches for "date" in that page2.php and since what I needed on page2.php was "dateyes", I replaced "date" with "dateyes".
On mainpage.php
$datetod = date("d/m", strtotime("now"));
$dateyes = date("d/m", strtotime("-1 day"));
$file = file_get_contents('../includes/page2.php');
if(strpos($file, "dateyes") !== false){}
else {
$str=str_replace("datetod", "dateyes",$file);
file_put_contents('../includes/page2.php', $str);
}
So I no longer worry about the cronjob which automatically copies $date from page1.php to page2.php everyday at 0:00am because the first person who loads/views the page (mainpage.php) is automatically going to change the $date in page2.php to $dateyes which is what I need.
I want to show user that he has vaccinated his goat after successfully payment confirmation.
Here is what I tried:
<?php
$treatperiod1=$product_row['treat1'];
$currentDate = date("Y-m-d");
$totalDays = $treatperiod1;
$usedDays = round(abs(strtotime($currentDate)-strtotime($orderdate))/60/60/24);
$remainingDays = $totalDays-$usedDays;
if($remainingDays==0) {
echo "<a target = '_blank' href ='product_addon.php?treatp=$treatperiod1' class='btn btn-success'><i class='fa fa-pencil'></i>Vaccinate Gaoat</a>";
} elseif($remainingDays==$treatperiod1) {
echo 'Vaccinated';
} else {
echo $remainingDays.' Days Left';
}
?>
I have displayed remaining days for vaccination intervals I want to also display 'Vaccinated' if user payment for vaccination is confirmed. $product_row['treat1']; is a column where the number of days for vaccination is specified. order_details is a table for orders with column confirm for confirmed orders.

Please read how to use PHP DateTime objects because they will make your life a lot easier on this project.
I will rewrite your code and then tell you what the new code does:
//establish DateTime objects.
$currentDate = new DateTime(); //now.
$orderDate = new DateTime($orderdate); //$orderdate format Y-m-d
//Establish how may days since order date and today.
$difference = $orderDate->diff($currentDate);
$usedDays = $difference->days;
/***
Total Period paid for,
in days, integer.
$product_row['treat1'];
***/
$remainingDays = $product_row['treat1'] - $usedDays;
//Returns an integer value of remaining days.
if($remainingDays < 1) {
echo "<a target = '_blank'
href ='product_addon.php?treatp=".$treatperiod1."'>
Vaccinate Goat</a>";
} elseif($remainingDays==$product_row['treat1']) {
//This will only fire if the goat was vaccinated TODAY.
echo 'Vaccinated';
} else {
echo 'Vaccinated:' .$remainingDays.' Days Left';
}
Hopefully with the help of the link above you should be able to see the basics of what I wrote out for you.
Some notes:
Stop making variables that are simply copies of other variables, it's inefficient and confusing.
(Try to) Stop sending data to new PHP pages as GET URL values such as /newpage.php?treatp=".$var.". This is very probably very insecure.
A more specific answer will need a full explanation from you of your MySQL tables, if nessecary please edit your question and add them.
Try and move away from using timestamps and treating timestamp variables as mathematical entities, and use the DateTime object instead.
Really, to determine if a payment is made you should have a payment date value in your database (set when a payment is successful) and simply compare this date to the value of the integer of the number of days payment covers, using the ->diff() method illustrated above.

I created two dropdown list for manage time. First dropdown list to manage hour in 24 hours format (Office Time) is 08.00-21.00. The second dropdown list is minutes 00-59. I blank.
<select id="Hour" class="input-small">
<?php
for ($i=8; $i<=21; $i++){
echo "<option value='".$i."'>" . $i ."</option>";
}
?>
</select>
:
<select id="Minutes" class="input-small">
<?php
for ($i=0; $i<=59; $i++){
echo "<option value='".$i."'>" . $i ."</option>";
}
?>
</select>
How to created this in php code ?
Sorry, the problem is in hour format :
let see. if 01, it printed 1. So, if user wanna to insert 01.00, it failed because the result is: 1.0 . It gives me error when I insert to database.
If you want to keep format : 01,02, ... you can make a function in php after submitting form to add 0 before the value under 10. Like :
if($_POST['Hour'] < 10 ){
$concat = "0".$_POST['hour'];
}
But it's not very clean.
You can use str_pad() : http://php.net/manual/fr/function.str-pad.php
(Thanks Raptor for the comment)
Your suggested format (08.00-21.00) is incompatible with database (well, I assume you're using MySQL). You didn't mention what is the data type of the column, but as in your case, you should be storing the information as VARCHAR.
To format the post values to your suggested format, you can use the following:
$open_time = str_pad($_POST['hour'], 2, '0', STR_PAD_LEFT) . '.' . str_pad($_POST['minute'], 2, '0', STR_PAD_LEFT);
p.s. you should give a name to your input <select>
I'm accessing a database created by another web company to retrieve event information for my current client. My client enters info for events and notes whether the date is recurring or not. I'm trying to display all the recurring dates. So far I have been able to get everything to display, regular dates as well as recurring.
The tables are laid out as follows:
Events
Events_Recurring
Here is part of the Events table BIGGER PICTURE
This is what the Events_Recurring table looks like
When the client checks it as recurring, the events_recurring table creates a row with the Event ID and other information like what day of the week or month the event is recurring on.
I'm just not sure how to display multiples of that certain ID that is recurring. I have a start date, and end date I can access, as well as what day of the week it is recurring on.
So for example: If this event reoccured every thursday. and I knew it started on Jan 1st and ended Jan 31st, can I run through that and spit out 4 different events all with the date of every Thursday in January?
Here is the full code I am working with, it's a little messy while trying to figure this out. I'm checking for the recurrence towards the bottom
// Access external database
$events_db = new wpdb(TOP SECRET CREDENTIALS HERE);
$events_db->show_errors();
if ($events_db) :
// Query Events Database
$events = $events_db->get_results(
"
SELECT ID, RequestDateStart, RequestDateEnd, Ministry, RequestTimeStart, EventName, CoordinatorName, EventDescription, Location
FROM gc_events
WHERE PrivateEvent = 0
AND Ministry = 15
AND date(RequestDateStart)>=date(NOW())
ORDER BY RequestDateStart
"
);
// Create the event data that will be displayed
foreach ($events as $event) :
// Store Event ID in a variable
$masterID = $event->ID;
echo '<div class="col-12">';
echo '<strong>ID:</strong> ' . $event->ID . '<br /><strong>Event Name:</strong> ' . $event->EventName . '<br /><strong>Leader:</strong> ' . $event->CoordinatorName . '<br /><strong>Date:</strong> ' . date('l, F j',strtotime($event->RequestDateStart)) . '<br /><strong>Start Time:</strong> ' . date('g:i a',strtotime($event->RequestTimeStart));
// CHECK IF RECURRING
$recurring_events = $events_db->get_results(
"
SELECT gc_event_id, period, day
FROM gc_event_recurring
WHERE gc_event_id = '$masterID'
"
);
foreach ($recurring_events as $recurring_event) :
if ($recurring_event->period === 'week') {
echo '<div class="col-12"><strong>↑ WEEKLY</strong><br />';
echo $recurring_event->day;
echo '</div>';
}
endforeach;
echo '</div>';
endforeach;
endif;
The result I am getting right now (with recurring events) is
Event: Weekly Prayer
Date: Feb 1, 2013
The result I would like is
Event: Weekly Prayer
Date: Feb 1, 2013
Event: Weekly Prayer
Date: Feb 8, 2013
Event: Weekly Prayer
Date: Feb 15, 2013
Event: Weekly Prayer
Date: Feb 22, 2013
This would be if the start date was Feb 1st and end date was Feb 28th.
A word of advice.
Although designing a database to store the 'description' of the repetition pattern is a very clean approach from a design point-of-view, you may get a lot of problems down the way.
I've done a project with a similar approach a while ago (I will look up the database design and add that to my answer) and, although I was able to reproduce the exact date/times of the recurring events, you will run into problems in the following situations; most originate from this:
the recurring events describe the repetition pattern, so the actual (individual) events are no physical records in your database
If the customer decides to add a new event, how will you check if it overlaps with any existing event? You'll have to calculate all 'events', based on the repetition pattern.
If the customer decides that the scheduled time for an event needs to be changed, how will you have this change apply to all future events and not for events that are in the past (you'll have to duplicate the original event, modify its end-date, and set the duplicated event with a new start-date)
If the customer decides he wants to remove a single day from the repetition pattern (e.g. a single event has ben canceled), you will also have to split the original event into two separate repetitions, or have a 'canceled/blocked' dates/times table
If people need to 'book' for specific events, you won't be able to attach them to a 'real' event-record, because the individual events because they are not physically present in the database. e.g. to check if a single event can be re-scheduled or canceled, you'll need to do this from code as the database cannot make use of foreign-key constraints to automatically update related reservations
Regarding performance; because individual events are not physically stored, they will have to be calculated every time you want to show them. Consider having 1000 recurring events in the database and try to show a 'calendar' of week 23 two years from now. You'll have to analyze all recurring-events patterns and calculate all events that they produce!
All depends of course on the actual usage of your system, but I wanted to warn you for problems we've run into.
Here's the schema for the 'schedules' table (contains recurring events pattern);
CREATE TABLE IF NOT EXISTS `schedules` (
`id` int(11) NOT NULL auto_increment,
`date_start` date NOT NULL,
`time_start` time NOT NULL,
`time_end` time NOT NULL,
`recur_until` date default NULL COMMENT 'end date when recurrence stops',
`recur_freq` varchar(30) default NULL COMMENT 'null, "secondly", "minutely", "hourly", "daily", "weekly", "monthly", "yearly"',
`recur_interval` smallint(5) unsigned default NULL COMMENT 'e.g. 1 for each day/week, 2 for every other day/week',
`recur_byday` smallint(5) unsigned default NULL COMMENT 'BITWISE; monday = 1, sunday = 64',
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 ROW_FORMAT=DYNAMIC;
How to circumvent the problems described
Fully describing a solution to these problems won't probably be suitable here, but here's some things to consider;
Storing a recurring event as described on itself is not bad practice. It perfectly describes when, and how often, an event should take place. However, the lack of physical records for the actual events is what causes the problem.
When creating or modifying a recurring event, calculate all resulting events and store them as physical records. These records can be queried, 'reservations' can be attached to them and you'll be able to make use of database features, like foreign-key-constraints to handle them properly.
When storing the individual events as described in 1., make sure you're keeping a reference to the 'schedule' that they belong to. If (for example) the customer wants to change the time of a recurring event, you'll be able to update all related (individual) events.
Keep in mind that in situation 2, you'll probably only want to update future events, so the 'recurring event' will still need to be 'split' in two to achieve that. In which case 'future' events need to be attached to the new 'recurring event', old events stay attached to the existing 'recurring event'
invest time in your database/software design, properly investigate if the design will 'work' for the thing you're trying to achieve. Test it, try things and if they don't work, don't hesitate to 'throw it away', often it's easier to start from scratch than try to 'fix' things. A proper design will take time and may take several 'redesigns' to get it right, but it will save you time and money in the end.
Hope this helps, good luck!
