Saving JobRelay rich text fields as meta data

Sometimes you might have a rich text field (containing things like HTML) sent over from JobRelay as the value of a field.

The best example of this is the job_description field. This contains HTML sometimes with formatting and images etc.

Although by default this is saved as the post_content field for the newly created or updated job, sometimes you theme might require this to be saved as a custom field instead.

All fields by default, have their values sanitized before they are saved. The default function for carrying this out is santiize_text_field. This removes HTML.

To prevent this happening for the job description field, the following code could be used, placing this either in your active themes functions.php file or in a plugin.

<?php
function hd_jobrelay_job_description_sanitize_callback( $callback, $post_id, $meta_key, $posted_key, $job_data ) {

	// if this is not the field with the posted key of job_description.
	if ( 'job_description' !== $posted_key ) {
		return $callback; // return the original callback.
	}

	// return the santized callback name for job description.
	return 'wp_kses_post';

}
add_filter( 'jobrelay_sanitize_meta_value_callback', 'hd_jobrelay_job_description_sanitize_callback', 10, 5 );
