Use Module Title as link in Joomla 1.6 , 1.7 , 2.5

1 – Open your module .xml file  example - modules/mod_articles_news/mod_articles_news.xml

2 –  Add the following line between the first set of <fieldset name=”basic”></fieldset> tags

<field name="title_link" type="text" default="" label="Title link" description="" />

Save your XML file.

3 – Now go to templates/system/html/modules.php open it & find the xhtml function or find this line “ xhtml (divs and font headder tags) ” here you can find this function

function modChrome_xhtml($module, &$params, &$attribs)
{
 if (!empty ($module->content)) : ?>
  <div class="moduletable<?php echo htmlspecialchars($params->get('moduleclass_sfx')); ?>">
  <?php if ($module->showtitle != 0) : ?>
   <h3><?php echo $module->title; ?></h3>
  <?php endif; ?>
   <?php echo $module->content; ?>
  </div>
 <?php endif;
}

& replace with

function modChrome_xhtml($module, &$params, &$attribs)
{
 if (!empty ($module->content)) : ?>
  <div class="moduletable<?php echo htmlspecialchars($params->get('moduleclass_sfx')); ?>">
  <?php if ($module->showtitle != 0) : ?>
   <?php $title_link = $params->get('title_link'); ?>
   <h3><?php if($title_link) { ?> <a href="<?php echo $params->get('title_link');  ?>"> <?php } ?><?php echo $module->title; ?><?php if($title_link) { ?></a><?php } ?></h3>
  <?php endif; ?>
   <?php echo $module->content; ?>
  </div>
 <?php endif;
}
