still looking for help regarding this , anyone here ?

* - Sakuto - Nov 25, 2014

Can you just show what the output of the data from the form (print_r($_POST)) ? Then it'll be very easy to format the data to match with the crontab file.

* - Br4v0 - Nov 26, 2014

here is crontab file that is dynamically updated with php

Code 
00 20 26 11 * /home4/dream45s/public_html/viral1/hot.php

can u help me with this ?

* - Sakuto - Nov 26, 2014

I wasn't talking about this but about the output of your form.

* - Br4v0 - Nov 26, 2014

when we do print_r() its something like this

Code 
Array ( [source] => 9gag_new [next_launch] => 11/27/2014 00:00 [day_interval] => 1 [hour_interval] => 0 [minute_interval] => 0 [posts] => 20 [status] => 1 )

The "start from" is the main part that fucked your script and make it hard. Do you really need it ?

i can re code everything
can you please give me idea ?

* - Sakuto - Nov 27, 2014

The problem is not from the code, the problem is from the CRON, you can enter value to repeat, but you can't specify a date to start the CRON. So you'll need to use an another CRON Task who will add the perpetual CRON Task to the list, and delete the last one.

Do you understand or I'm not clear ?
PS : Don't PM me each time you answer, I come watch every subjet...

i doesnt matter if i dont specify date , how do i specify hours minutes , & after how many days

* - Sakuto - Nov 30, 2014

I don't understand where the problem is, you just need 3 inputs (day, hour, minute)

Structure of the cron will be : minutes hours /day * php execute.php
Where's the problem ?

* - Sakuto - Dec 2, 2014

PHP Code 


<?php
if(isset($_POST['submit'])) {
    $cron = "*/{$_POST['Minutes']} */{$_POST['Hours']} */{$_POST['Day']} * * execute.php";
    echo $cron;
}
?>
<form action="Cron.php" method="post">
    <input type="text" placeholder="Hours" name="Hours"><br>
    <input type="text" placeholder="Minutes" name="Minutes"><br>
    <input type="text" placeholder="Day" name="Day"><br>
    <input type="submit" name="submit">
</form> 

According to http://cron.schlitt.info/index.php , the output is correct and do perfectly what you want.
(To test your output into the website, just remove the execute.php)

oh thanks a ton
will try it now 🤝

I can't actually test it on a true Server, but if it doesn't work, I know how to make the script to generate the sequence properly.

It will just look like this (for repeating every 30 minutes, 2 hours, 2 days) :

0,30 0,2,4,6,8,10,12,14,16,18,20,22 /2 *

Just test the previous code and if it doesn't work, I will give you the second option code.
