XF 1.1 Cron Entry for CometChat

[Jeff Fuqua]

I'm attempting to create a cron entry every three hours to run this file:

http://www.yoursite.com/cometchat/cron.php

I see how to add one but don't understand the cron callback and where I insert the link.

 

[Jake Bunce]

The callback needs a class and method within XenForo's namespace. Create a directory and PHP file to define a class. For example, create:

library/Comet/Cron.php

<?php

class Comet_Cron
{
	public static function runCron()
	{
		include 'http://www.yoursite.com/cometchat/cron.php';
	}
}

Then your callback would be:

Class = Comet_Cron
Method = runCron

Thanks for your reply.

There's already a cron.php on the root for another xenforo add-on. Can I name this "cron2.php" and change the code you gave me to say "runCron2" on the fifth line?

Can I name this "cron2.php" and change the code you gave me to say "runCron2" on the fifth line?

Yes. But you need only update this code:

include 'http://www.yoursite.com/cometchat/cron2.php';

 

[Jeff Fuqua]

I think I goofed up with my info.

There is already a cron.php in the cometchat folder which, I assume is what is supposed to run.

In their info on optimizing, they say:

Run http://www.yoursite.com/cometchat/cron.php periodically (every 3 hours)

 

[Jake Bunce]

Did you create the library/Comet/Cron.php file in your xenforo directory?

 

[Jeff Fuqua]

Sorry for the confusion.

The Comet folder was installed on the root. There is no Comet folder in the library right now.

Do I need to make one?

Yes.

 

[Jeff Fuqua]

Okay. Got a Cron.php file as you outlined in post #2 above and placed it in a Comet folder in the library. Here's the result when I made a run:

Server Error

Alternatively you can specify the server path to the file:

include '/path/to/cometchat/cron2.php';

Alternatively you can specify the server path to the file:

include '/path/to/cometchat/cron2.php';

Having worked on your server, Jeff, for you the code would be

include '/home/yourFTPusername/public_html/library/Comet/Cron.php';

 

[Jeff Fuqua]

That took care of it. The first time I ran it, I got an error but tried again and it went through fine.

Thanks for all the help.

I am trying to do something similar - I want to create some tables on my database and have the php file:

/library/UpdateRatingsComments/Ratings.php

to do the job.

I want a cron to run the php regularly.

I have created the following Cron.php file:

<?php
 
class Ratings_Cron
{
    public static function runCron()
    {
        include 'http://www.arsenaltalk.net/library/UpdateRatingsComments/Ratings.php';
    }
}

When creating my cron I am using

Class : Ratings_Cron
Method : runCron

however I get the following error:

"Please enter a valid callback method." when trying to create the cron job

What am I doing wrong here?

 

[jayramfootball]

I think I got it - I have to call the class the same as the folder name

Thanks guys!
i finally managed to deal with this cometchat cron.php

 

[grunjuger]

Finally not completely solved. I got this error...

Anyone can help me? Thanks!

Your custom cron is apparently generating output which it shouldn't do. Try using an output buffer to capture the output (and then not use it). Code example here:

http://xenforo.com/community/threads/creating-a-page.5714/page-2#post-90582

 

[grunjuger]

Sorry but after reading and reading, I don't understand what I should do...
Quite noob in this kind of modifications...

 

[Jake Bunce]

Surround your require or include line with ob functions. This is the code example linked above:

        ob_start();
        require('/path/to/your/html/file.html');
        $myContent = ob_get_contents();
        ob_end_clean();

 

[grunjuger]

Hum ok but what should I use instead of the

$myContent

???

Currently my file looks like this:

 <?php
 
class Comet_Cron
{
    public static function runCron()
    {
        include '/home2/grenon/public_html/cometchat/cron.php';
    }
}
