Removing WordPress menu div tag and keeping ul [Code Snippet]

When you are working with WordPress menu then sometimes you may noticed if no menu is defined it is putting a div wrapper just above the url tag. Here is how you can remove that div and keep ul as it as.

wp_nav_menu( 
    array( 
        'theme_location'  => '', //Just keep this as empty
        'container'       => '', //Keep this one also as empty
        'menu_class'      => 'menu',
        'menu_id'         => 'primary-menu',
        'depth' => '2',
    )
);

Checking if a menu published in WordPress

$has_enabled_main_menu = false; 
$menu_location = 'primary'; //Going to check if this menu location (primary) has a menu as defined
$menu_locations = get_nav_menu_locations();
$menu_object = ( isset( $menu_locations[ $menu_location ] ) ? wp_get_nav_menu_object( $menu_locations[ $menu_location ] ) : null );
if( $menu_object ) {
    $has_enabled_main_menu = true;
}

Finding all parent pages in WodPress [Code Snippet]

Sometimes we needs to find all parent pages of current page in WordPress. It is useful to create a breadcrumb. Here is a example code snippet to find all parent pages.

<ul class="page-breadcrumbs">
    <li><a href="<?php echo home_url(); ?>"><?php _e( 'Home', 'mondira' ) ?></a></li>
    <?php
    global $post;
    $parent_id = $post->post_parent;
    $breadcrumbs = array();
    while ( $parent_id ) {
        $page = get_page( $parent_id );
        $breadcrumbs[] = '<li><a href="' . get_permalink( $page->ID ) . '">' . get_the_title( $page->ID ) . '</a></li>';
        $parent_id = $page->post_parent;
    }
    $breadcrumbs = array_reverse( $breadcrumbs );
    foreach ( $breadcrumbs as $crumb ) echo $crumb;
    ?>
    <li><a href="<?php the_permalink(); ?>"><?php the_title();?></a></li>
</ul>

WordPress sidebars fetching on other cms with wordpress xml rpc

Recently I worked on a site which is using wordpress as it’s cms and creloaded as it’s web shop. So the wordpress was top of the shopping cart and then the shopping cart as webshop. So basically I had to develop the site using wordpress and then had to install that creloaded inside woordpress installation.

For main site wordpress has it’s header (with navigation), footer (with navigation and other contents), sidebar with widgets etc. So when I am visiting the web shop with creloaded I was required to show the same layouts and design. For that I had to use wp xmlrpc to fetch those common features into creloaded system.

XML-RPC functionality is turned on by default since WordPress 3.5. So anyone can use it who is using wp 3.5 or greater without activating xml-rpc via wordpress admin!

All of this can be done with below written 3 steps.
1. Writing XML Client Class
2. Using XML Client
3. Defining XML Server methods in wp functions.php

Note: Here all the things are not well documented, Because I am assuming you are enough expert on wp and did some google and finally here to see a code example of wp xml rpc implementations.

Replacing media urls on wordpress posts

Sometimes we work for a website with wordpress keeping the development version on sub directory. Say are working for http://www.example.com website and currently it is live and we work for it’s new version in wordpress. So we setup a new wordpress version on new folder so the current development version is http://www.example.com/new

When we are done with all development and uploaded all contents on that new setup that means all media files and contents media urls are targeting with http://www.example.com/new

So when we are going to make the site live we need to do something manually to replace media paths for contents. Or if we directly copy contents from another hosting in that case same things will happen.

For the faster replacement of each media guid, contents media url or other meta values below mentioned 3 mysql query is nice.

Note: After running below code we need to ensure that all wp-contents/uploads folders contents are available as it was on new development directory.

update wp_posts set guid = replace(guid, 'http://www.example.com/new', 'http://www.example.com')

update wp_posts set post_content = replace(post_content, 'http://www.example.com/new', 'http://www.example.com')

update wp_postmeta set meta_value = replace(meta_value, 'http://www.example.com/new', 'http://www.example.com')

update wp_options SET option_value = 'http://www.example.com' WHERE option_name = 'home' OR option_name = 'siteurl';

 

With this above queries below listed things will happen –
1. Replace all resource or post guid
2. Replace all old media src url to new src url in post contents
3. Replace all meta resource url like image, video or audio etc
4. Replace site home page and siteurl url
