Contact Form 7 – Populate Select List With Taxonomy

1 comment

1. The following is a more up to date way to dynamically populate the built-in select with options and could easily be extended to support more.

   /**
    * Dynamic Select List for Contact Form 7
    * @usage [select name taxonomy:{$taxonomy} ...]
    * 
    * @param Array $tag
    * 
    * @return Array $tag
    */
   function dynamic_select_list( $tag ) {
   
       // Only run on select lists
       if( 'select' !== $tag['type'] && ('select*' !== $tag['type']) ) {
           return $tag;
       } else if ( empty( $tag['options'] ) ) {
           return $tag;
       }
   
       $term_args = array();
   
       // Loop thorugh options to look for our custom options
       foreach( $tag['options'] as $option ) {
   
           $matches = explode( ':', $option );
   
           if( ! empty( $matches ) ) {
   
               switch( $matches[0] ) {
   
                   case 'taxonomy':
                       $term_args['taxonomy'] = $matches[1];
                       break;
   
                   case 'parent':
                       $term_args['parent'] = intval( $matches[1] );
                       break;
   
               }
           }
   
       }
   
       // Ensure we have a term arguments to work with
       if( empty( $term_args ) ) {
           return $tag;
       }
   
       // Merge dynamic arguments with static arguments
       $term_args = array_merge( $term_args, array(
           'hide_empty' => false,
       ) );
   
       $terms = get_terms( $term_args );
   
       // Add terms to values
       if( ! empty( $terms ) && ! is_wp_error( $term_args ) ) {
   
           foreach( $terms as $term ) {
   
               $tag['values'][] = $term->name;
   
           }
   
       }
   
       return $tag;
   
   }
   add_filter( 'wpcf7_form_tag', 'dynamic_select_list', 10 );

   The below is an older/original way to do this and should be considered outdated.

   /** Dynamic List for Contact Form 7 **/
   /** Usage: [select name term:taxonomy_name] **/
   function dynamic_select_list($tag, $unused){ 
       $options = (array)$tag['options'];
   
       foreach ($options as $option) 
           if (preg_match('%^term:([-0-9a-zA-Z_]+)$%', $option, $matches)) 
               $term = $matches[1];
   
       //check if post_type is set
       if(!isset($term))
           return $tag;
   
       $taxonomy = get_terms($term, array('hide_empty' => 0));
   
       if (!$taxonomy)  
           return $tag;
   
       foreach ($taxonomy as $cat) {  
           $tag['raw_values'][] = $cat->name;  
           $tag['values'][] = $cat->name;  
           $tag['labels'][] = $cat->name;
       }
   
       $tag['raw_values'][] = 'Other';  
       $tag['values'][] = 'Other';  
       $tag['labels'][] = 'Other - Please Specify Below';
   
       return $tag; 
   }
   add_filter( 'wpcf7_form_tag', 'dynamic_select_list', 10, 2);
