How to disable wordpress html filter for posts and pages?

Published by admin on 24 Oct ’11

In some versions of WordPress there is a filter that strips some tags from the html code. If you want to remove this filter just open wp-includes/kses.php and find this row:

function kses_init_filters() {
    // Normal filtering.
    add_filter('pre_comment_content', 'wp_filter_kses');
    add_filter('title_save_pre', 'wp_filter_kses');

    // Post filtering
    add_filter('content_save_pre', 'wp_filter_post_kses');
    add_filter('excerpt_save_pre', 'wp_filter_post_kses');
    add_filter('content_filtered_save_pre', 'wp_filter_post_kses');
}

and comment out the rows that you need:

function kses_init_filters() {
    // Normal filtering.
    add_filter('pre_comment_content', 'wp_filter_kses');
    add_filter('title_save_pre', 'wp_filter_kses');

    // Post filtering
    //add_filter('content_save_pre', 'wp_filter_post_kses');
    add_filter('excerpt_save_pre', 'wp_filter_post_kses');
    //add_filter('content_filtered_save_pre', 'wp_filter_post_kses');
}

Then if you save the post in html it’s OK, but if you switch to normal view and then go back to html view the tags could be stripped again. This hapens most likely from the MCE Editor and to resolve this issue you could install a plugin called TinyMCE Valid Elements or some similar plugin.

Using the Page Class Suffix in Joomla templates and components

Published by admin on 15 Jul ’11

Load Suffix

First, we need to find out what the page class suffix is for the page we are visiting. To do this, you will need add some code to your template:

  1. Open your template’s index.php file (located in /templates/*template-name*/)
  2. Find the <head> tag in the index.php, near the top area of the template
  3. Above this, insert one of the following code blocks (Either of the following options will work fine in most cases. However they work slightly differently, so in certain cases your needs may dictate a specific choice.)

By Itemid

To load the page class suffix associated with the current Itemid, add this to the top of the index.php file:

<?php
  $itemid = JRequest::getVar('Itemid');
  $menu = &JSite::getMenu();
  $active = $menu->getItem($itemid);
  $params = $menu->getParams( $active->id );
  $pageclass = $params->get( 'pageclass_sfx' );
?>

By Active Menu Item

To load the page class suffix associated with the active menu item, add this to the top of the index.php file: (For sub-pages with no active menu item, this will load the page class suffix for the default menu item.)

<?php
   $menus      = &JSite::getMenu();
   $menu      = $menus->getActive();
   $pageclass   = "";

   if (is_object( $menu )) :
   $params = new JParameter( $menu->params );
   $pageclass = $params->get( 'pageclass_sfx' );
   endif; 
?>

Security

You should always use htmlspecialchars() in your code before writing something into an HTML attribute, else you open up an attack vector to inject script code into your page.

Insert Suffix

The next step is to use the page class suffix somewhere in the template.

In the Body Tag

The more common method would be to apply the page class suffix as an id or class to the <body> tag. Find the <body> tag (below the </head> tag) and replace it with this:

<body id="<?php echo $pageclass ? htmlspecialchars($pageclass) : 'default'; ?>">

To Load a Page-Specific Stylesheet

The second method would be to load a stylesheet unique to the page in question. Instead of modifying the <body> tag, look for the stylesheet link within the <head></head> tags and add the following line directly beneath it:

<link rel="stylesheet" href="templates/<?php echo $this->template ?>/css/<?php echo htmlspecialchars($pageclass) ?>.css" type="text/css"/>

Fix for a problem with Joomla K2 and sh404sef

Published by admin on 18 Nov ’10

First some explanation about the problem.

The situation is when you have a Joomla 1.5 site with sh404sef 2.1.4 component and you want to add additional section for a blog for example and you want to use K2 2.4 for this.

So in this case you have additional menu item called for example ‘blog’ where you see a blog of your K2 articles. But you also want to have the tags and the search.

The problem is that when you hit on a tag you go to the page with the tags but you don’t see the other modules for the ‘blog’ item (you are redirected to a page without Itemid).

The same is with the search results page.

And one additional fix for a prefix in the url for your K2 blog.
