BB Code

I want to add a new BB Code and handle it with PHP

Ive been looking through the BB Code include file and I really dont understand how its working

Heres what I want to do:

Take a string of links, each link on one line. Then convert that into an array:

PHP Code:


		
			
$string = '[mybbcode]

http://www.site1.com/

http://www.site2.com/

http://www.site3.com/

[/mybbcode]



$string = explode("\n", $string);



foreach($string as $link){

     echo '<a href="'. $link . '">'.$link.'</a>';

}

Thats essentially what I want to do, amongst other things.

But Im reallly lost.:o

To add a BB code processed by a custom callback, you need to define it in a plugin at bbcode_fetch_tags.

Ive got that far but I dont know what to do from there.

And you know what is passed to your callback function?

What do you mean?

What are you putting in the plugin @ bbcode_fetch_tags?

1Unreal

I havent done anything yet. Thats what Im saying, Im completly lost.

Could you give a brief explanation/tutorial of how to add custom BB Codes as a plugin?

Look what I found when I did a search.

Ok this is what ive started off with.

bbcode_create:

PHP Code:


		
			
function handle_bbcode_parts($value)

{

        return 'Your videos:'. $value;        

}

bbcode_fetch_tags:

PHP Code:


		
			
// [PARTS]

$tag_list['no_option']['parts'] = array(

    'callback' => 'handle_bbcode_parts',

    'strip_empty' => true

);

However when I view a thread I get this error.

Look carefully at the plugin example @ bbcode_fetch_tags (especially at what value is what).

1Unreal

Does the callback have to direct to an external file?

Dismounted

Look at the plugin:

PHP Code:


		
			
// [VIDEO]
$tag_list['no_option']['video'] = array(
    'callback' => 'handle_external',
    'external_callback' => 'handle_bbcode_video',
    'strip_empty' => true
);

Which value do you think is the custom one?

1Unreal

callback/external_callback depending which way you do it.

Dismounted

You change "external_callback"... "callback" only calls methods that are defined in the class.

1Unreal

05-20-2009 12:15 AM

Ok, I dont really understand. Do I have to use 'callback' somewhere within the function?

Dismounted

Read the entire bits of code I posted. Find the correlations between "external_callback" and defined function names.

1Unreal

05-20-2009 07:02 AM

The callback has to correlate with the function name. Which mine does :\

Dismounted

Again, "callback" only calls methods that are defined in the class. This type of custom BB code defines a function that is global - hence the need to use "handle_external" as the callback. You specify your own callback in "external_callback". Hoping you could figure this out yourself.

bbcode_fetch_tags:

PHP Code:


		
			
// [VIDEO]
$tag_list['no_option']['video'] = array(
    'callback' => 'handle_external',
    'external_callback' => 'handle_bbcode_video',
    'strip_empty' => true
);

bbcode_create:

PHP Code:


		
			
// include our custom functions
require_once(DIR . '/inc.php');

Contents of inc.php:

PHP Code:


		
			
<?php
function handle_bbcode_video($value)
{
        return 'Your videos:'. $value;        
}
?>

Thats what ive got. It doesnt work.

Can I not simply do a return like that? Do I have to do it with a class?

Look at the comments on the handle_external() method in class_bbcode.php. ;)

1Unreal

Im really lost, its not making sense. Its like its not detecting the callback. :|

Also, is this possible with the BB Code parser in vB. I know there are some limitations. $string would have to be the bit picked up between the tags. I dont want to be doing this then realise its not possible :p

PHP Code:


		
			
<?php
$string = 'http://www.link1.com
http://www.link2.com
http://www.link3.com';

$string = explode("\n", $string);
$num = 0;
foreach($string as $item){
    $num++;
    $item = trim($item);
    echo '<a href="'.$item.'" class="parts">'.$num.'</a>';    
}
?>

Use the code I posted in the other thread, and modify:

The function name handle_video_bbcode() (or whatever it was).
"external_callback" to new function name.
Code inside the [previous] handle_video_bbcode() function.

Look at the arguments in the function.

You do not need to do anything else - that is - don't modify "callback".
