Search specific category in wordpress

Jim — Mon, 28 Nov 2011 10:43:05 +0000

There are some times when you want to limit your search to a particular category, or perhaps multiple categories. This is relatively simple to do in WordPress by adding a hidden field to your search code. (See example below)

form method="get" id="search form" action="/"
input type="text" value="" name="s" id="s"
input type="hidden" value="22" name="cat" id="scat"
/form

You can see I added my hidden input field on the third line. When I add this in, it then adds onto the query used to search. Your search will go from something like http://www.wordpress-designer.co.uk/?s=WordPress to http://www.wordpress-designer.co.uk/?s=WordPress&cat=22 and will only return posts in the category ID you choose.

Remove p tags from images

Simply paste the following code on your theme functions.php file, save it, and the

tags are gone.

function filter_ptags_on_images($content){
    return preg_replace('/\s*()?\s*()\s*(<\/a>)?\s*<\/p>/iU', '\1\2\3', $content);
}

add_filter('the_content', 'filter_ptags_on_images');

Thanks to James for the great hack!

Add multiple menus to a wordpress site

Jim — Tue, 02 Aug 2011 15:03:29 +0000

Recently I need to implement multiple menu in wordpress. Often we comes in the situation where theme support only 1 menu whereas we need more than it. There is simple way I found in wordpress to do it by changes in few lines of code.

register_nav_menus function is the primary menu (default menu in wordpress), you can find in function.php file. Search for “register_nav_menus” you will find it.

You need to replace the code there for the code below to get a second menu item:

// This theme uses wp_nav_menu() in one location. register_nav_menus( array( 'primary' => __( 'Primary Navigation', 'twentyten' ), ) );register_nav_menus( array(
‘footer’ => __( ‘Footer Navigation’, ‘twentyten’ ),
) );

Now go to appearance ->menus for setting links under footer menu. That’s It.

Menu tabs available in wordpress 3.0 or latest versions.

Add post thumbnails to RSS feed

This very cool piece of code will get the post thumbnail and automatically add it to your RSS feeds.

Paste the code into functions.php and save the file.

Don’t forget that you need to use a theme that supports post thumbnails for this snippet to work.

function cwc_rss_post_thumbnail($content) { global $post; if(has_post_thumbnail($post->ID)) { $content = '< p >' . get_the_post_thumbnail($post->ID) . '< /p >' . get_the_content(); } return $content; } add_filter('the_excerpt_rss', 'cwc_rss_post_thumbnail'); add_filter('the_content_feed', 'cwc_rss_post_thumbnail');

Increasing the upload filesize in WordPress

Jim — Wed, 18 May 2011 17:48:18 +0000

I had problems with editing the php.ini file because with most webhosts it is globally and inaccessable for us and you still would have to add a line in .htaccess anyway.

However, I found an easier way if you have access to the .htaccess file in your www folder. Just include the following 2 lines in .htaccess:

php_value upload_max_filesize 20M php_value post_max_size 20M

For changing the memory limit add/edit this in .htaccess:

php_value memory_limit 20M

And of course change the 20 to anything you need.

Or you can follow the steps at wptheming – http://wptheming.com/2009/07/upload_max_filesize if the above does not work.
