Custom Field Checkboxes created with Types not showing on Front-End

replaced in ajax.php line 259

if( isset( $field['meta'] ) && is_array( $field['meta'] ) ):
	foreach( $field['meta'] as $m ):
		$meta = get_post_meta( get_the_ID(), $m, true );
		//$meta = get_postmeta_values ($m);
		$return = array( 'add_this' => false, 'meta_key' => $m );
		$check = sf_types_is_checkbox( $return );
		if( $check['add_this'] ):
			$meta = apply_filters( 'sf_get_postmeta_values', $meta );
		endif;
		if( is_array( $meta ) ) :
			$fullvalue = '';
			// Need a safer check against wpcf groups
			foreach($meta as $mkey => $mvalue)
				$fullvalue .= $mvalue[0];
			$template_single = preg_replace( '^#meta_' . preg_quote( $m ) . '#^', $fullvalue, $template_single );
		else :
			$template_single = preg_replace( '^#meta_' . preg_quote( $m ) . '#^', $meta, $template_single );
		endif;
	endforeach;
endif;

now it seems to work ??

errr… sorry I later realized that the function sf_get_postmeta_values was meant for completely different purposes

not being able to know a Types plugin native alternative
whereas the type of the field could be more simply checked with _wpcf_is_checkboxes_field( $m );

I changed the applied filters to

$meta = apply_filters( 'sf_post_meta_key_values', $meta, get_the_ID(), $m );
$meta = maybe_unserialize($meta);

and added them in the init (e.g. includes\types-checkboxes.php)
add_filter( 'sf_post_meta_key_values', array( $this, 'sf_types_postmeta_values_of_checkboxes' ), 10, 4 );

and finally the new function

function sf_types_postmeta_values_of_checkboxes( $return, $object_id, $meta_key, $single=false ){

	if( !preg_match( '^wpcf^', $meta_key ) )
		return null;
	//if ( !_wpcf_is_checkboxes_field( $meta_key ) )
	$keycheckbox = array( 'add_this' => false, 'meta_key' => $m );
	$checkbox = sf_types_is_checkbox( $keycheckbox );
	if( $checkbox['add_this'] )
		return null;

	$meta_cache = wp_cache_get($object_id, 'post_meta');

	if ( !$meta_cache ) {
		$meta_cache = update_meta_cache( $meta_type, array( $object_id ) );
		$meta_cache = $meta_cache[$object_id];
	}
	if ( ! $meta_key ) {
		$return = $meta_cache;
	}elseif( isset($meta_cache[$meta_key]) ) {
		if ( $single )
			$return = maybe_unserialize( $meta_cache[$meta_key][0] );
		else
			$return = array_map('maybe_unserialize', $meta_cache[$meta_key]);
	}elseif ($single)
		$return = '';
	else
		$return = array();

	if(is_array($return) && !empty($return)) {
		$types = get_option( 'wpcf-fields' );
		$choices = array();
		//echo '<pre>'; print_r($types); echo '</pre>';
		foreach( $types as $type ){
			if( isset( $type['data']['options'] ) && isset( $type['meta_key'] ) && $type['meta_key'] == $meta_key ){
				foreach( $type['data']['options'] as $index => $option ){
					if(isset($return[$index]) && !empty($return[$index]))
						if( isset( $type['type'] )&& $type['type'] == 'checkboxes' )
							if(isset($option['set_value']) && in_array($option['set_value'], $return[$index]) && !in_array($option['set_value'], array_keys($choices)))
								$choices[$option['set_value']] = $option['title'];
						elseif( isset( $type['type'] )&& $type['type'] == 'select' )
							if(isset($option['value']) && in_array($option['value'], $return[$index]) && !in_array($option['value'], array_keys($choices)))
								$choices[$option['value']] = $option['title'];
				}
			}
		}
		if( count( $choices ) > 0 ){
			sort($choices);
			$choices = array_unique(array_filter($choices));
			//print_r($choices);
			if ($single)
				return maybe_serialize($choices);
				//return '<ul><li>'.implode('</li><li>', $choices).'</li></ul>';
			else
				return $choices;
		}
	}
	return $return;
}

however, I had to further fork the original code to support manipulating output with a filter at the end of the sf_do_search function in ajax.php
$data = apply_filters('sf-get-search-data',$data,$args);

it would be extremely useful in a possible future update, in addition to the already existing and useful previous query $args filtering, to have the chance to filter the output data array as well

Hi 3dolab,
thanks for all your work. Well, over Christmas, I do not really quickly react as you can see. So thanks a bunch, I will look into the code and see how to implement it.

Thanks a bunch!
