Replacing all links on the page via php code

Oops it's a comment, sorry :)

arg does not work....haven't seen you want to remove the link completely

The point is that the argument of onClick = "myfunction(argument)" is exactly the same as the href.

How can I extract the href and place it as onClick to the same link?

ed987,

I tried your code, but it does not replace anything. This is the simplified example of what i need:

current link:

<a href="index.php?main_page=index&cPath=1_17">test</a>

converted link:

<a href="#" onClick="myfunction('index.php?main_page=index&cPath=1_17'); return false">test</a>

===========================================================

As I mentioned, the point is to make myfunction() with the same argument as the href value

<?
      preg_match_all('/href="(.*?)"/',$content, $urls);
      print_r($urls);
?>

preg_match_all('/href="(.*?)"/i',$div, $urls);
//print_r($urls);
foreach($urls[1] as $url)
      $div = str_ireplace($url."\"", "#\" onClick=\"myfunction('$url'); return false\"", $div);
//print $div;

às

still wrong output.

preg_match_all('/href="(.*?)"/i',$div, $urls);
print_r($urls);

returns something like

array([1]=>array([0]=>'includes/modules...')) etc

no href substring whatsoever

could you post a small part of your html code you want to parse, just to have a look at your url format?

Here is a sample of the html code to be transformed. I have checked ed987's code and it seem to be working, though I need to test it more on different links.

One question - how to add a filter to the regex to replace ONLY links containing substring 'index.php' or index2.php? There could be some links to outside url's, which should not be modified

    <div id="navBreadCrumb">  <a href="http://69.64.xx.xx/">Home</a>&nbsp;::&nbsp;
 
Hardware
 
</div>
 
<!-- eof breadcrumb -->
 
<div class="centerColumn" id="indexCategories">
 
<h1 id="indexCategoriesHeading">Hardware</h1>
 
<div id="categoryImgListing" class="categoryImg"><img src="images/categories/category_hardware.gif" alt

<div id="categoryDescription" class="catDescContent">We offer a variety of Hardware from printers to
 
 graphics cards and mice to keyboards.</div>

You might consider this code:

$div = preg_replace('/<\s*a\s+href\s*=\s*"(.*?)"\s*>/s','<a href="#" onClick="myfunction('$1'); function2(); return false">',$div);

Thank you guys - I am getting closer. The us111's regex works OK and replaces ALL links, i.e.

$div2=preg_replace('/<a[ \t\n\r]*href[ \t\n\r]*=[ \t\n\r]*"([^"]*)"([^>]*)>/i','<a href="#" onClick="xajax_multiply(\'\1\'); mySpinner(); return false"\2>',$div2);

Next, I am trying to add a filter to replace only links containing main_page=index or main_page=product_info

Here is my code attached:

It does not work. What is wrong here? I am placing the fixed string main_page=index|main_page=product_info between [^"]*, which allow averything except ".

Where am I making the mistake here?

$div2=preg_replace('/<a[ \t\n\r]*href[ \t\n\r]*=[ \t\n\r]*"([^"]*main_page=index|main_page=product_info[^"]*)"([^>]*)>/i','<a href="#" onClick="xajax_multiply(\'\1\'); mySpinner(); return false"\2>',$div2);

andy7789, did you attempt my code from post 20548124?  I would use preg_replace_callback to add an additional test for main_page=index|main_page=product_info.  If you are interested in a solution let me know.

ddrudik, your code is working also. I have come up with the following regex:

Thank you, guys, for help. Happy New Year!

$div2=preg_replace('/<a[ \t\n\r]*href[ \t\n\r]*=[ \t\n\r]*"([^"]*(main_page=product_info|main_page=index)[^"]*)"([^>]*)>/i','<a href="#" onClick="xajax_multiply(\'\1\'); mySpinner(); return false"\2>',$div2);
