Hi all

I'm quite a competent PHP coder but where it comes to preg_match I prefer to be ignorant, because I can't get my head around the patterns.

Basically, I'm working with a script that someone else has written, and I'm coming across problems because the URL that is being validated sometimes has curly brackets '( )' in it (these are image file names generated by an internal system). I have the pattern, how do I modify this to allow curly brackets? On some occasions, the urls have just the opening or just the closing, so its never the complete set.

if someone could give me an indication with this, because I'm clueless! Thanks in advance!

Ste

pattern:
Code: [Select]
$pattern = '/^(([\w]+:)?\/\/)?(([\d\w]|%[a-fA-f\d]{2,2})+(:([\d\w]|%[a-fA-f\d]{2,2})+)?@)?([\d\w][-\d\w]{0,253}[\d\w]\.)+[\w]{2,4}(:[\d]+)?(\/([-+_~.\d\w]|%[a-fA-f\d]{2,2})*)*(\?(&?([-+_~.\d\w]|%[a-fA-f\d]{2,2})=?)*)?(#([-+_~.\d\w]|%[a-fA-f\d]{2,2})*)?$/';

Please help me with this code. It keep appear in my website.

"Warning: preg_match() [function.preg-match]: No ending delimiter '.' found in /home/kengsite/public_html/wp-content/plugins/statpress/statpress.php on line 1184"

And this is how the line look like.

if (!preg_match(".ico$", $urlRequested)) { return ''; }

Hi,

I want to separate out the file name from an image url. Not sure the best way to do it? I want to basically select all text after the last / slash. eg - image.jpg would be the result from http://www.google.com/images/image.jpg

What's the best way to do it?

Cheers

Rob

Hi,

Say you had, <business_name type="string">L Choong</business_name>, contained inside a variable(content before and after this in the same var), how would you extract the 'L Choong' information as a new var?

Thanks

$name = preg_replace('{(\d+)}', convertNumber("$1"), $row['name']); 


why isnt this working?

im having trouble using this function. im trying to change the strings within a post.

eg:

Code: [Select]
This is an example post
[attachment=file.png]

what im trying to do is change [attachment=file.png] to file.png.

Here is the code i have but it doesnt change anything.


$p_content = str_replace('<br>', '', $post_info[$key]['p_content']);
        $attach = preg_split('|\[attachment=|', $p_content);
        
        for($i=0; $i<count($attach); $i++)
        {
            $attach[$i] = str_replace(']', '', $attach[$i]);
            if(file_exists($config['asf_root'].'attachments/'.$attach[$i]))
            {
                $p_content = preg_replace('|\[attachment=([0-9a-zA-Z\.-_])\]|#i', $attach[$i], $p_content);
            }
        }
        echo $p_content;


it first gets all the attachment tags within the post then applies the preg replace to all of them. But the preg replace isnt replacing, so i must have gone wrong somewhere.
Any tips/ideas?

Thanks

Hello,

I come from a C and PERL background.

I seem to have trouble finding how to do this easily.  What is the PERL equivalent of:

$var =~ s/^\+//g;    // remove a plus from the beginning, and from the entire string.

Thanks.

So i have this script  that outputs Listed Files inside a folder

    echo '<option value="'.$fileName.'">'.$fileName.'</option>';}

like this :

<option value="Fonts/28 Days Later.ttf">Fonts/28 Days Later.ttf</option> etc files ....

i would like to know how may i remove  " Fonts/ " And the .ttf extension from the second part that repeats (the name) using something like preg_replace and to make the first letter uppercase using ucfirst()


And if someone is familiar with preg_replace
could you please give me a tutorial on how it works to replace some text ?

Thanks In Advance

basically what i am trying to do is replace the

<a href="whatever.com"> 

with

<a href="whatever.com" onclick = "if (! confirm("Continue?")) return false;">

so that when the user clicks the url in a message the box pops up first then redirects them to the url if they click confirm. However i am getting the following error:

Code: [Select]
Warning: preg_replace() [function.preg-replace]: Compilation failed: reference to non-existent subpattern at offset 11
here is the code i used.

$message_content = $content_info['message_content'];
$pattern='<a href="\\1">';
$replace='<a href="\\1" onclick = "if (! confirm("Continue?")) return false;">';
$message_content = preg_replace($pattern, $replace, $message_content);
echo $message_content;

Anyone know where i went wrong?
