How to add image source into post meta

[Santel]

Hello everyone,

I believe most of us at least use one image in the blog post. I usually go to search for creative commune licensed photo on the Flickr. Previously I insert a link manually back to image source inside the image caption.

Now I want to add image source directly inside the post meta. Here are the step by step guide if you want to do the same thing:

1. Add a custom field from the blog post, I named it "image_source", then put the url of the image source

2. Create a short code to get the custom field as below:

add_shortcode( 'image_source', 'genesis_image_source_shortcode' );
/**
 * Add source code for image source.
 */
function genesis_image_source_shortcode( ) {
    $image_source = genesis_get_custom_field( 'image_source' );

    if ( ! $image_source )
        return;

    $output = sprintf( '<span class="image_source">Credit: <a href="' . genesis_get_custom_field( 'image_source' ) .'" target="_blank" rel="nofollow">Image Source</a></span>');

    return apply_filters( 'genesis_image_source_shortcode', $output );
}

3. Add shortcode to the meta

add_filter( 'genesis_post_meta', 'post_meta_filter' );
/**
 * Customize the post meta function.
 */
function post_meta_filter( $post_meta ) {
    if ( ! is_page() )
        $post_meta = '[post_categories before="Filed Under: "] [post_tags before="Tagged: "][image_source] ';

    return $post_meta;
}

I am very new to php but this work for me. Hopefully you will find it useful.
