Multi-line captions on attachments

1 comment

1. I don’t think you can do that, however you can implement this code in your functions file to at least allow for line breaks in single image captions

   Note: doesn’t work for gallery images (I am trying to find a way to make it work in galleries)

   /*
   *********************************************
   Function to allow multi-line photo captions.
   This function will split captions onto multiple lines if it detects
   a "|" (pipe) symbol.
   **********************************************
   */
   /* Override existing caption shortcode handlers with our own */
   add_shortcode('wp_caption', 'multiline_caption');
   add_shortcode('caption', 'multiline_caption');
   
   /* Our new function */
   function multiline_caption($attr, $content = null) {
   extract(shortcode_atts(array(
   'id' => '',
   'align' => 'alignnone',
   'width' => '',
   'caption' => ''
   ), $attr));
   
   if ( 1 > (int) $width || empty($caption) )
   return $content;
   
   if ( $id ) $id = 'id="' . esc_attr($id) . '" ';
   
   $new_caption = str_replace("|", "<br />", $caption);
   
   return '<div ' . $id . 'class="wp-caption ' . esc_attr($align) . '" style="width: ' . (10 + (int) $width) . 'px">'
   . do_shortcode( $content ) . '<p class="wp-caption-text">' . $new_caption . '</p></div>'; }
