Hey

[waynew]

Need some help on this one. Say for example that I have:

 

 

edede

deededed

<code>

kejhkjdkejdkejkde</code>

 

ededed

 

(bad example I know.) How would I take out everything inside the code tags?

Erm, very vague. What kind of code is it? If you mean return everything from within two tags, say a div element(?) you could use JavaScript with something like:

 

var content = document.getElementById('yourElementsID').innerHTML;

 

... (or ".value" depending on the element, like an 'input' for example)

 

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

 

To return the JS code I have no idea, don't know if you can? Need bit more information really...

Sorry, it was early in the morning.

 

You see, I'll be re-doing my website soon and I want to format my posted PHP code a lot better. What I wish to do is get any code that is between a <code> or

 tag and send it through:

[code=php:0]
$string = highlight_string($string);

 

Only anything that is between the <code> tags should be sent through that function however, otherwise everything will look like code.

 

Obviously this is a job for some sort of string function where I can take out a specific part and then highlight it before putting it back.[/code]

You could do this with normal string manipulation or regular expressions. The former is simpler and faster, but surely lacks the power of regular expressions and most importantly, it would be really difficult to parse the text if it has several code tags. I'm not a regular expression guy, but from my humble knowledge I came up with this:

 

<?php
$str = "here is some code: [ code ]put some code here[ /code ]";
$pattern = "/\[code\](.*?)\[\/code\]/is";
preg_match($pattern, $str, $matches);
echo $matches[1];
?>

 

Basically the regular expression searches for a pattern of any text which is enclosed in code tags, doesn't care about case (meaning case insensitive) and takes care of newlines too. Hope this helps.

 

EDIT: Added some space in the code tags of the string in the code i suggested, because they were interpreted as forum code tags. Just remove them when you will test the code.

GuiltyGear. My many thanks! I've been wondering about this for a while but never needed to use it, so it lay there waiting for me. Cheers!
