Search and replace but only if another string is present

[Phalynx]

What is the correct code to accomplish a search & replace with specific parameters?

 

I have for example this:

[TD=class: myclass]Dynamic String, can contain all chars, simple?

[TD=class: myclass]Another Dynamic String, yup!

 

I want this:

[TD="class: myclass"]Dynamic String, can contain all chars, simple?

[TD="class: myclass"]Another Dynamic String, yup!

 

 

So just remove the URL tag BUT only if prefixed with the [td BBCode

 

I tried already these pattern with preg_match_all, but failed miserably:

'/\[TD="class: myclass"\]\[url="http:\/\/my.com\/static/<.*>/'

 

Does anyone has a solution? Thanks in advance...

I doubt this can be solved with a single RegEx.

 

This requires parsing of values RegEx returns, probably with more RegEx.

You can include the TD in the search text so long as you remember to put it back when you're done.

//             v------1------v               v-2-v
preg_replace('/(\[TD=[^\]]+\])\[uR L=[^\]]+\](.*?)\[\/URL\]/i', '$1$2', $string)

(Don't forget to remove the space from the "UR L")

BBCode shoudn't be parsed in code/php tags

 

Many people like to use [url=http://google.com]this[/url]

It doesn't get translated to HTML, but the forum does add a http:// prefix. After copy/pasting what I typed and removing the space,

preg_replace('/(\[TD=[^\]]+\])\[url=http://[^\]]+\](.*?)\[\/URL\]/i', '$1$2', $string)

Now as it turns out, that's not actually harmful in this case, but still...

Interesting! Odd behavior, good to know!

Great, it works! Thank you.
