The only way to do this is by using the following filter to alter the value:
https://www.admincolumns.com/documentation/filter-reference/ac-column-value/
Based on your screenshot, something like the following snippet should work.
/**
* @param $value string
* @param $id int
* @param $column AC_Column
*/
function ac_column_value_excluded_pages( $value, $id, $column ) {
if ( $column instanceof ACP_Column_CustomField ) {
$meta_key = $column->get_meta_key(); // This gets the Custom Field key
if ( '_fl_theme_builder_exclusions' == $meta_key ) {
$records = explode( ', ', $value );
$results = array();
foreach ( $records as $record ) {
$parts = explode( ':', $record );
// Define the parts of the URL as variables
$meta_type = $parts[0];
$post_type = $parts[1];
$id = $parts[2];
$result = $id;
// If it is a (custom) post type, we can create a link with the title for it
if ( 'post' === $meta_type ) {
$result = ac_helper()->html->link( get_edit_post_link( $id ), get_the_title( $id ) );
}
$results[] = $result;
}
// Remove empty records
$results = array_filter( $results );
$value = implode( '<br>', $results );
}
}
return $value;
}
add_filter( 'ac/column/value', 'ac_column_value_excluded_pages', 10, 3 );
