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;
}
