|
|
|
* Use this method in case you want to alter the parsed bbcode. |
|
51
|
|
|
* The newline placeholders are still available and any remaining will be removed in the last step before output |
|
52
|
|
|
* |
|
53
|
|
|
* Example: you want the "img" bbcode to use database images instead of user URLs. |
|
54
|
|
|
* You'd go and change the tag so that it only accepts digits like [img=123456] |
|
55
|
|
|
* and replace any occurence with a unique placeholder like {__IMG#ID__}. |
|
56
|
|
|
* Now the post-parser gets into play: you preg_match_all() out all your placeholders, |
|
57
|
|
|
* grab the images in a single query from the database and replace them with their respective <img> tag |
|
58
|
|
|
* or whatever replacement and any corrupt id with a placeholder image. Profit! |
