Someone contacted me to develop a function that would add a login form to the primary navigation for their Genesis menu, and I would like to share it with you.

[php]';
$login .= '';
$login .= '';
$login .= '';
$login .= ' Remember me';
$login .= '';
$menu .= '

';
}
// if logged in, do logout link
else {
global $current_user;
get_currentuserinfo();
$logout = '';
$logout = 'Welcome ' . $current_user->display_name;
$logout .= 'Logout';
$menu .= '

';
}

return $menu;
}
[/php]

Recently I read an awesome post by Bill Erickson about customizing WordPress menus. However, there are two things I wanted this class to do that in its original form it doesn't do.

So since out of the box, WordPress doesn't intuitively allow you to add descriptions to the menu without requiring some custom code, rather the Walker class extended.

Since Bill has done an excellent job at this I will extend his code to add the options of having a featured image and/or descriptions applied based on depth.

Add this to your functions.php file.

All Menus

To highjack ALL of your menus, enter this code in your functions.php.

Menus Based on Location

To highjack a menu based on registered and assigned location, then use this code in your functions.php.

Menus via WordPress Custom Menu Widget

To highjack a custom menu based menu id that is called using the custom menu widget, or even a manual method (if the menu is being called by a location, you must use 'theme_location'), then use this code in your functions.php. This will highjack any menu called by the custom menu widget assuming you only have the standard registered theme locations. The example below assumes a standard theme custom menu registered locations for Genesis. Change 'primary' and/or 'secondary' to whatever your theme adds and add whatever more menus that your theme has to only target the custom menu widget.

There is a caveat though. There are certain menu items that may not have a featured image such as custom links, categories, etc. There is a possible work-around that I am trying to work out.

Here is the result of a sandbox description and featured images for all types (not just pages and posts), which I will be posting soon or writing up into a plugin...

Recently, in order to dummy proof a metabox that accepts a file upload via Media Library from a user accidentally selecting something other than Original Image like Small, Medium, or Large, I wrote a validation script to check and correct this.

This function will change a thumbnail URL (http://domain.com/wp-content/uploads/2011/08/example_2a-158x300.jpg) to the original URL (http://domain.com/wp-content/uploads/2011/08/example_2a.jpg). To use this function, simply:

[php]$url = wps_get_original_image( $url );[/php]

Here is the script that can be added to your functions.php:

[php]<!--?php function wps_get_original_image( $url ) { global $_wp_additional_image_sizes; $new_url = $url; // Get All Image Sizes $builtin_sizes = array( 'large' =--> array(
'width' => get_option('large_size_w'),
'height' => get_option('large_size_h')
),
'medium' => array(
'width' => get_option('medium_size_w'),
'height' => get_option('medium_size_h')
),
'thumbnail' => array(
'width' => get_option('thumbnail_size_w'),
'height' => get_option('thumbnail_size_h')
)
);

$image_sizes = array_merge( $builtin_sizes, $_wp_additional_image_sizes );

//$url = 'http://webendev.com/review/scheumanndental/wp-content/uploads/2011/08/example_2a-300x158.jpg';

// Parse URL
$info = pathinfo( $url );

// Check to see if it is a post-thumbnail: assuming size < 999x999 so -999x999.jpg = 12chars $pos = strrpos($info['basename'], '-', -1); $length = strlen( $info['basename'] ); if ( ( $length - $pos ) > 12 )
return $url;

// Check to see if image is indeed a thumbnail and not example-2.jpg

// Get image size extensions, e.g. -200x200
// Get image size width only extensions, e.g., -200x
// Get image size height only extensions, e.g., x200.
$image_exts = array();
$image_exts_width = array();
$image_exts_height = array();
foreach ($image_sizes as $image_size) {
$image_exts[] = '-'.$image_size['width'].'x'.$image_size['height'];
$image_exts_width[] = '-'.$image_size['width'].'x';
$image_exts_height[] = 'x'.$image_size['height'];
}

// Cycle through image size extensions, e.g. -200x200
foreach ( $image_exts as $image_ext ) {
//if found, simply replace with nothing (easy)
$new_url = str_replace( $image_ext , '' , $url );

//report changed url
if ( $new_url != $url )
break;
}

// if a new url hasn't been generated...
if ( $new_url == $url ) {
// Cycle through image width only extensions, e.g. -200x
foreach ( $image_exts_width as $image_ext ) {

// check for width, e.g., -200x
$pos1 = strrpos( $info['basename'] , $image_ext , -1 );
if ( $pos1 ) {
// strip, & assign new url
$new_url = $info['dirname'] . '/' . substr( $info['basename'] , 0 , $pos1 ) . '.' . $info['extension'];
}

if ( $new_url != $url )
break;
}

// if a new url hasn't been generated...
if ( $new_url == $url ) {
// Cycle through image height only extensions, e.g. x200.
foreach ( $image_exts_height as $image_ext ) {

// check for height, e.g., x200
$pos2 = strrpos( $info['basename'] , $image_ext , -1 );

//example_2a-263x300.jpg -> example_2a.jpg
if ( $pos2 ) {
// get position of -, strip, & assign new url
$pos3 = strrpos( $info['basename'] , '-' , -1 );
$new_url = $info['dirname'] . '/' . substr( $info['basename'] , 0 , $pos3 ) . '.' . $info['extension'];
}

if ( $new_url != $url )
break;
}
}
}

if ( $new_url != $url )
return $new_url;
else
return $url;
