PHP Examples

A small hack to set the default Itemid for new posts added into the admin panel can be done at 2 places in the file:  components/com_sef/joomsef.php Line: 1462                     if (isset($Itemid) && ($Itemid != '')) {                         $col = ', `Itemid`';                         $val = ", '171'";                      // Itemid of the menu item, which is included for almost all modules in our site                     } Line: 1567  ...

Sometimes, we face certain jquery conflicts in Joomla. These can be avoided by using jQuery instead of $ in your code. For example, instead of: $(function() {         $( "#tabs" ).tabs();     }); Use this: jQuery(function() {         jQuery( "#tabs" ).tabs();     }); And in your template index (or head includes script file), add a js file (noconflict.js) with just this content: jQuery.noConflict(); For example: $this->addScript($this->baseurl."/templates/".$this->template."/js/jquery-1.7.1.js"); $this->addScript($this->baseurl."/templates/".$this->template."/js/noconflict.js");

Then we want to force the user to login page (if he is not already logged in) and then redirect back to our page after logging in, and show a custom logout button. This is a sample code in our component view: <?php $user =& JFactory::getUser(); global $mainframe; if($user->id == 0) { $return_url = 'index.php?option=com_comments'; $return_url = urlencode(base64_encode($return_url)); $redirect_url = '&return='.$return_url; $login_url = 'index.php?option=com_user&view=login'; $finalUrl = $login_url . $redirect_url; $mainframe->redirect( $finalUrl, 'Please login or register before you post comment' ); } else {  ?> <table width="800"> <tr><td><?php echo 'Welcome <b>'.$user->name; ?></b></td> <td align="right"> <form id="l...
