Encoded Masks for a custom field

You will have to add just a line in a theme code where you output custom field data.

To add same preprocessing for data as for comment text, use

$metadata = apply_filters( ‘comment_text’, $metadata );

For example, if you use some kind of metadata, it should look like this:

// get data from wordpress database
$metadata = get_post_meta( $id, ‘MetaTagName’, true );

// add this line of code for preprocessing field value 
$metadata = apply_filters( ‘comment_text’, $metadata ); 

//output preprocessed field value
echo $metadata;

Use the_content instead of comment_text if you want to use the same masking policy as for post text.
