Forward Slash & New Line Issue, Urgent Pls.

[buzzdeep]

Hi PHP Experts...I'm new to regex expressions and facing a problem.

 

$pattern = "/\[amp (.*?)\](.*?)\[\/amp\]/";

 

This is suppose to look for tags [amp showbox=true|otheroptions=false] some text [/amp]

 

Now this word fine as long as I use the following text in the fronted:

 

[amp showbox=true|otheroptions=false]Click here to download[/amp]

 

But it breaks when I use any of the following:

 

[amp showbox=true|otheroptions=false]<a href=http://someurl.com>Click here</a> to download[/amp]

 

Possibly because of closing </a> as it has a forward slash.

 

[amp showbox=true|otheroptions=false]
Click here to download
[/amp]

 

Possibly because of new line returns.

 

[amp showbox=true|otheroptions=false]<h3>Click here to download</h3>[/amp]

 

Possibly because of closing </h3> as it has a forward slash.

 

Could someone please help modify the regex expression to take care of all the three situations?

 

Thanks

Easy. Use '%' as your regex delimiter. And add the DOTALL flag so it goes past newline (\n).

 

$pattern = '%\[amp (.*?)\](.*?)\[\/amp\]%s'

No, didn't work

 

It still doesn't take </ ...new line is also not working...atelast if I can make it work for closing html tag (</) that should help me for now...

Then you're doing something wrong. Show me your full code. Don't forget the 's' at the end of the regex.

    $pattern = '%\[amp (.*?)\](.*?)\[\/amp\]%s';
    preg_match_all($pattern, $content, $matches);

    for ($loop1 = 0; $loop1 < sizeof($matches[1]); $loop1++)
    {
        $protected_content = $matches[2][$loop1];
        $fields = explode("|", $matches[1][$loop1]);
        for ($loop2 = 0; $loop2 < sizeof($fields); $loop2++){
            $colums = explode("=", $fields[$loop2]);
            
            for ($loop3 = 0; $loop3 < sizeof($colums); $loop3++){
                
                switch($colums[$loop3]) {
                
                    case "error":
                        $error = trim($colums[$loop3+1]);
                    break;

                    case "pid":
                        $pid = trim($colums[$loop3+1]);
                    break;

                    case "showbox":
                        $showbox = trim($colums[$loop3+1]);
                    break;
                

                    default:
                    break;
                }   
            }
        }

 

If I use the reg expression you gave me then doesn't enter in the for loop at all. I use this content in the front end which is passed to the function that parses using regex code above.

 

[amp showbox=true|error=You must be logged in, <b>with an active subscription</b>, to access this file. |pid=53]<a href=http://yahoo.com>Click here to download this lesson</a>[/amp]

Anyone?

[xyph]

His expression works with the example you've provided. The problem isn't in the RegEx.

[buzzdeep]

Yes, my bad..thanks.

 

But now I'm stuck at the preg_replace part. I'm using this..

 

 

                        $pattern = '%\[amp (.*?)\]". $protected_content ."\[\/amp\]%s';
                        $form = function_login_form();
                        $content = preg_replace($pattern, $form, $content);                        

 

...but apparantly, preg_replace is not able to find that pattern because it doesn't replace the pattern in the content with the form.

 

Any ideas?

Without knowing what $protected_content or $form hold, it's very hard to advise.
