Cel PHP in Custom BBCode
 

Installation:
- install the product file - done.


Using PHP in Custom BBCodes:
Create your Custom BBCode as always, and just put your PHP into the Replacement box (where the HTML used to go).

Just remember two things:

• Your code needs to start with <?php
• You need to return the result of your code.

If you're unsure what that means, read the php manual on eval() and look at the evaltest example in the second post.

For coders: include instead of eval
If you'd rather store the PHP for your new BBCodes in the file system for ease of development, that's possible, too:

• create a folder called "custombbcodes" in your forum root
• in that folder, create a php file that copies your BBCode Tag Name (ie. if your tag name is "includetest", the file needs to be called "includetest.php"). That's where your PHP goes.
• in the Replacement box in the Custom BBCode Dialog, just put the word "include", nothing else
• Since there's no eval() here, no need to return the result. Instead, it needs to go into $parsed.There's also an includetest example in the second post.

PHP BBCode Examples:

To test them, go to AdminCP->Custom BB Codes->Add new BB Code and fill in the form:

--------------------------------------------------------------------

• Title: evaltest
• BBCode Tag Name: evaltest
• Replacement:

• Example: [evaltest]Hello World![/evaltest]
• Use {option}: No

--------------------------------------------------------------------

• Title: includetest
• BBCode Tag Name: includetest
• Replacement:

[code]include[code]

• Example: [includetest="World!"]Hello![/includetest]
• Use {option}: Yes

Additionally, you need to create a directory called custombbcodes, and in it create a file called includetest.php with the following code:
--------------------------------------------------------------------

i want to include, xx.txt.

it's not work. How can i do that?

Please have a look at the examples in the second post, and mark the mod as installed.

What's {param} supposed to be? You want to use $value for what I think you meant to achieve:
As explained in the examples: The variables {option} maps to $option, {param} maps to $value.

Been in further contact with troyuncucom. If you want to use include in your PHP code, make sure there is PHP Code in the file you include. Because of how vB works it is not possible to just throw text in there and have it printed to the screen. This will cause a cookie error/header already sent.

You need to make sure that you don't print to the screen directly; all output needs to go to a variable and needs to be correctly returned/passed. Please look at the examples in second post!

I did it all, firstly thanks very much.

But 2 errors for this plugin.

1) if i use bbcode, sending the message twice.

2) if i modify my txt file. the message does not change

Those are not errors caused by this plugin, but by the code you're trying to run. What you can do and can't do is subject to the same limits as general vB plugin coding, since you're acting within the same framework.
Your first point I don't understand, and regarding your second point: Edit and save the message once again. Post output is cached.

Isn't parsed BBcode in posts cached if you enable the vb post cache? If so, that would mean that writing custom code to hide things from guests wouldn't be of much help, right?

Not bbcodes are cached, but the entire post (as I wrote in the post above). Hiding things would have to be done at runtime, like the existing hide hacks do. This is not something this framework provides, you would have to do that yourself.

Edit: Thinking about it - you could clear the post from postcache at runtime using something like this:
One would have to test if this could be of use in the environment my addon creates, or whether a seperate plugin could be created that deletes a post from postcache when a certain custom bbcode is present, or a plugin that keeps a post from being entered into postcache in the firstplace if a certain custom bbcode is present.

This just does not work. It loads once, then disappears.
I've tried to alter it, my code, etc ...
