Run JavaScript if a file is created

Oy, why do it that way … your index.php will never get updated if there’s an upstream change in the code (because we use index.html). You should use the existing infrastructure in MM². Create a new module, have it display in a specific region on the mirror. Every 5 minutes, have the module refresh by doing a call to its node_helper. The node_helper can be a simply python script that checks the specific file in question and reports back to the module.

I thought the PHP script was doing something … it’s not in this case. You don’t need PHP at all for this.

Some places to look for coding ideas:
MM² Module Development Documentation
Look at how modules such as the calendar and newsfeed implement a node_helper which does the background tasks

You could still use PHP to do the file checking for you, but to me that’s a bit of an unnecessary overhead.

@KirAsh4 LOL - I’m just lost these days with all of this stuff. I should stick to my DB work.

Let me see what I can do with the module documentation, it would be a good experience anyway to learn.

@KirAsh4 Just out of curiosity, if I were to add the code you provided into the PHP file, would i need to bracket it with <?php then add the code here?>

This is hard to answer because I don’t know what your PHP file looks like. I don’t know if you are echo-ing HTML data, or using HEREDOC? I’m flying blind here … (as much fun as that could be)

@KirAsh4 I had actually uploaded that file a few posts back. For reference here’s the entire thing (forgive the ugliness)

Then yes, write the proper PHP code and stick it in <?php ... ?> tags.

@KirAsh4 awesome, I will give it a shot. I can’t thank you enough! Much appreciated!

EoF · Jul 29, 2016, 1:56 PM

@KirAsh4 Ah I wasn’t aware this was for MM2. Thought he was still using MM1. Didn’t know you could run PHP scripts on MM2.

KirAsh4 · Jul 29, 2016, 4:24 PM

@EoF, you can, as an external process, just like everything else. :)
