PHP bbcode url code not working

[csharplearner]

Hi all,

i have this bbcode for a which is not working.
Please let me know whats wrong with it.

// Perform URL Search

 $post = preg_replace("/\[url\]([$URLSearchString]*)\[\/url\]/", '<a href="javascript:go(\'$1\',\'new\')">$1</a>', $post);


$post = preg_replace("(\[url\=([$URLSearchString]*)\](.+?)\[/url\])", '<a href="javascript:go(\'$1\',\'new\')">$2</a>', $post);

Thank you.

It could be because you are using the wrong call back for the preg_replace.

Here's how I've done it in the past:

while(preg_match("#\[url=([^\]]+)\](.+?)\[/url\]#ies",$articledata)){
    $articledata=preg_replace("#\[url=([^\]]+)\](.+?)\[/url\]#ies","BuildLinks(array('0'=>2,'1'=>'\\1','2'=>'\\2'))", $articledata);
    }

  function BuildLinks($arr){
    switch($arr['0']){
    case 1:
        $ret="<a href=mailto:{$arr['1']} rel='extern'>{$arr['2']}</a>";
        break;
    case 2:
        $ret="<a href='{$arr['1']}' rel='extern'>{$arr['2']}</a>";
        break;
    }
    return $ret;    
  }

Hi all,

i have this bbcode for a [URL] which is not working.
Please let me know whats wrong with it.

// Perform URL Search

$post = preg_replace("/[url]([$URLSearchString]*)[\/url]/", '<a href="javascript:go(\'$1\',\'new\')">$1</a>', $post);

$post = preg_replace("([url\=([$URLSearchString]*)](.+?)[/url])", '<a href="javascript:go(\'$1\',\'new\')">$2</a>', $post);

Thank you.

Nope :( it isnt working.

here is my entire bbcode

// Perform URL Search



 $Text = preg_replace("/\[url\]([$URLSearchString]*)\[\/url\]/", '<a href="javascript:go(\'$1\',\'new\')">$1</a>', $Text);


$Text = preg_replace("(\[url\=([$URLSearchString]*)\](.+?)\[/url\])", '<a href="javascript:go(\'$1\',\'new\')">$2</a>', $Text);


//$Text = preg_replace("(\[url\=([$URLSearchString]*)\]([$URLSearchString]*)\[/url\])", '<a href="$1" target="_blank">$2</a>', $Text);


// Convert new line chars to html <br /> tags

 $Text = nl2br($Text);

That is because you are using $1 and $2 instead of \\1 and \\2 for the call backs.

$1 and $2 mean nothing.

i replaced \\1 and \\2 with $1 and $2 in the code.. but it just shows up as link instead of giving it a link

I think they meant for you not to use $1 and $2 as these are PHP variables which have not been assigned and so meant nothing to the script :)

The problem could also be with your regular expression.

I take it you are trying to make it more dynamic allowing someone to define the regex using the variable $URLSearchString .

Since I can't see what is defined this could be where the problem lies as well. Have you tried to use the regex from my example in place of yours?

//$Text = "[url]http://www.google.com/";
$Text = "fdsfd_shttp://";

$Text = preg_replace("/\[url\]([a-z\:\/\.]*)\[\/url\]/",
					 '<a href="javascript:go(\'${1}\',\'new\')">${1}</a>',
					  $Text);
		

$Text = preg_replace("/\[url\=([a-z\:\/\.]*)\]([a-zA-Z0-9_\:\/]*)\[\/url\]/",
					 '<a href="javascript:go(\'${1}\',\'new\')">${2}</a>',
					 $Text);
			
echo $Text;

Missing braces...

[csharplearner]

Are you talking about {1} {2} braces above? I have made changes accordingly but it too didnt work.:(

[csharplearner]

here is my entire code .
pls: see below

<?php
 

 function BBCode($Text)
{
  
// Set up the parameters for a URL search string
 $URLSearchString = " a-zA-Z0-9\:\/\-\?\&\.\=\_\~\#\'";

// Set up the parameters for a MAIL search string
 $MAILSearchString = $URLSearchString . " a-zA-Z0-9\.@";

//Non BB URL Search
//$Text = eregi_replace("([[:alnum:]]+)://([^[:space:]]*)([[:alnum:]#?/&=])", "<a href=\"\\1://\\2\\3\" target=\"_blank\" target=\"_new\">\\1://\\2\\3</a>", $Text);

//$Text = eregi_replace("(([a-z0-9_]|\\-|\\.)+@([^[:space:]]*)([[:alnum:]-]))", "<a href=\"mailto:\\1\" target=\"_new\">\\1</a>", $Text);


if (substr($Text,0, 7) == "http://"){

$Text = eregi_replace("([[:alnum:]]+)://([^[:space:]]*)([[:alnum:]#?/&=])", "<a href=\"\\1://\\2\\3\">\\1://\\2\\3</a>", $Text);

// Convert new line chars to html <br /> tags
 $Text = nl2br($Text);


} else {

// Perform URL Search



 $Text = preg_replace("/\[url\]([$URLSearchString]*)\[\/url\]/", '<a href="javascript:go(\'${1}\')">${1}</a>', $Text);


$Text = preg_replace("(\[url\=([$URLSearchString]*)\](.+?)\[/url\])", '<a href="javascript:go(\'${1}\',\'new\')">${2}</a>', $Text);


//$Text = preg_replace("(\[url\=([$URLSearchString]*)\]([$URLSearchString]*)\[/url\])", '<a href="${1}" target="_blank">${2}</a>', $Text);


// Convert new line chars to html <br /> tags

 $Text = nl2br($Text);


}
 // Perform MAIL Search

$Text = preg_replace("(\[mail\]([$MAILSearchString]*)\[/mail\])", '<a href="mailto:$1">$1</a>', $Text);
$Text = preg_replace("/\[mail\=([$MAILSearchString]*)\](.+?)\[\/mail\]/", '<a href="mailto:$1">$2</a>', $Text);

 
 
 
 
 
 
 
 
 $CodeLayout = '<table width="90%" border="0" align="center" cellpadding="15" cellspacing="0">

 <td class="quotecodeheader"> Code:</td>

 <tr>

 </tr>

 </table>';

 

 $Text = preg_replace("/\[code\](.+?)\[\/code\]/is","$CodeLayout", $Text);

 
 $QuoteLayout = '<table width="90%" border="0" align="center" cellpadding="0" cellspacing="0">


 <tr> <td class="quotecodeheader"> Quote:</td> </tr>

 $Text = preg_replace("/\[quote\](.+?)\[\/quote\]/is","$QuoteLayout", $Text);
 
 
return $Text;

 }

What does fulfil <b></b> tags into <a href="..." code ?

$Text = preg_replace("/\[url\]([$URLSearchString]*)\[\/url\]/", '<a href="javascript<b></b>:go(\'${1}\')">${1}</a>', $Text);

$Text = preg_replace("(\[url\=([$URLSearchString]*)\](.+?)\[/url\])", '<a href="javascript<b></b>:go(\'${1}\',\'new\')">${2}</a>', $Text);

Those tags only displayed when I change to plain text.
