[Plugin: Custom Field Template] shortcode

Sure you can
Here’s what you have to do.
place this in your functions.php file
<?php

$new_meta_boxes =
array
(
“contact_wp_info” =>
array
(
“name” => “Video”,
“std” => “”,
“title” => “Featured Youtube Video”,
“description” => “”
)
);

function new_meta_boxes()
{
global $post, $new_meta_boxes;
$wpcm_tab_index = 1000;
foreach($new_meta_boxes as $meta_box)
{
$meta_box_value = get_post_meta($post->ID, $meta_box[‘name’].’_wpcm_value’, true);
if($meta_box_value == “”)
$meta_box_value = $meta_box[‘std’];
echo'<input type=”hidden” name=”‘.$meta_box[‘name’].’_noncename” id=”‘.$meta_box[‘name’].’_noncename” value=”‘.wp_create_nonce( plugin_basename(__FILE__) ).'” />’;
echo'<p><label style=”letter-spacing:1px; text-transform:uppercase; color:#777;” for=”‘.$meta_box[‘name’].’_wpcm_value”>’.$meta_box[‘title’].'</label>
‘;
echo'<input style=”padding:4px; font-weight:normal; border-top:1px solid #ccc; border-right:1px solid #ddd; border-bottom:1px solid #ddd; border-left:1px solid #ccc;” type=”text” name=”‘.$meta_box[‘name’].’_wpcm_value” value=”‘.$meta_box_value.'” size=”55″ tabindex=”‘.$wpcm_tab_index.'” /></p>’;
$wpcm_tab_index++;
}
}

function create_meta_box()
{
global $theme_name;
if ( function_exists(‘add_meta_box’) )
{
add_meta_box(‘new-meta-boxes’, ‘Media Information’, ‘new_meta_boxes’, ‘post’, ‘normal’, ‘high’);
}
}

function save_postdata( $post_id )
{
global $post, $new_meta_boxes;
foreach($new_meta_boxes as $meta_box)
{
// Verify
if ( !wp_verify_nonce( $_POST[$meta_box[‘name’].’_noncename’], plugin_basename(__FILE__) ))
{
return $post_id;
}
if ( ‘page’ == $_POST[‘post_type’] )
{
if ( !current_user_can( ‘edit_page’, $post_id ))
return $post_id;
}
else
{
if ( !current_user_can( ‘edit_post’, $post_id ))
return $post_id;
}

$data = $_POST[$meta_box[‘name’].’_wpcm_value’];

if(get_post_meta($post_id, $meta_box[‘name’].’_wpcm_value’) == “”)
add_post_meta($post_id, $meta_box[‘name’].’_wpcm_value’, $data, true);
elseif($data != get_post_meta($post_id, $meta_box[‘name’].’_wpcm_value’, true))
update_post_meta($post_id, $meta_box[‘name’].’_wpcm_value’, $data);
elseif($data == “”)
delete_post_meta($post_id, $meta_box[‘name’].’_wpcm_value’, get_post_meta($post_id, $meta_box[‘name’].’_wpcm_value’, true));
}
}

add_action(‘admin_menu’, ‘create_meta_box’);
add_action(‘save_post’, ‘save_postdata’);

?>

Then in your single.php file place the following.
<div class=”video”>
<?php $videos = get_post_meta($post->ID, ‘videos_wpcm_value’, true); ?>
<?php
$galx = $videos;
$galx = apply_filters(‘the_content’, $galx );
echo $galx;
?>
</div>

Hope this works for you

Happy coding…

I forgot to mention about the shortcode, it would be something like this in your custom field.
[playlist id=1]

Have fun…

issy-m,
Your code rocks and was exactly what I needed for a project. However, I would suggest one update:

Swap the two elseif statements in save_postdata to be:

elseif($data == "") delete_post_meta($post_id, $meta_box['name'].'_wpcm_value', get_post_meta($post_id, $meta_box['name'].'_wpcm_value', true));
elseif($data != get_post_meta($post_id, $meta_box['name'].'_wpcm_value', true)) update_post_meta($post_id, $meta_box['name'].'_wpcm_value', $data);

Otherwise, it takes saves to delete blank values.
Cheers!
