Adding caption to image link.

  • Hi I am trrying to integrate the image caption in the image href.

    It’s getting a bit complicated for my skills!

    here’s the code i need to modify in media.php:

    <div class='gallery'>");

	$i = 0;
	foreach ( $attachments as $id => $attachment ) {
		$link = isset($attr['link']) && 'file' == $attr['link'] ? wp_get_attachment_link($id, $size, false, false) : wp_get_attachment_link($id, $size, true, false);

		$output .= "<{$itemtag} class='gallery-item'>";
		$output .= "
			<{$icontag} class='gallery-icon'>
				$link
			";
		if ( $captiontag && trim($attachment->post_excerpt) ) {
			$output .= "
				<{$captiontag} class='gallery-caption'>
				{$attachment->post_excerpt}
				</{$captiontag}>";
		}
		$output .= "</{$icontag}></{$itemtag}>";
		if ( $columns > 0 && ++$i % $columns == 0 )
			$output .= '<br style="clear: both" />';
	}

    I know its in this part:$link = isset($attr['link']) && 'file' == $attr['link'] ? wp_get_attachment_link($id, $size, false, false) : wp_get_attachment_link($id, $size, true, false);
    but I am not able to put my caption inthe $link…

    If somebody knows that would be great.
    Thanks heaps.

    hi, have you found a way how to do this?

    Firstly, I would recommend making these modifications in a plugin, or more easily, in your theme’s functions.php.

    From the link you provided, I’ve taken a guess at what you are after. Copy the below into your theme’s functions.php and see how it goes!

    Note: I have removed the <style>..</style> tags from the gallery output. You should put the CSS you require in your theme’s style.css.

    function tt_gallery_shortcode($attr)
{
	global $post;

	static $instance = 0;
	$instance++;

	// Allow plugins/themes to override the default gallery template.
	$output = apply_filters('post_gallery', '', $attr);
	if ( $output != '' )
		return $output;

	// We're trusting author input, so let's at least make sure it looks like a valid orderby statement
	if ( isset( $attr['orderby'] ) ) {
		$attr['orderby'] = sanitize_sql_orderby( $attr['orderby'] );
		if ( !$attr['orderby'] )
			unset( $attr['orderby'] );
	}

	extract(shortcode_atts(array(
		'order'      => 'ASC',
		'orderby'    => 'menu_order ID',
		'id'         => $post->ID,
		'itemtag'    => 'div',
		'icontag'    => 'span',
		'captiontag' => 'span',
		'columns'    => 3,
		'size'       => 'thumbnail'
	), $attr));

	$id = intval($id);
	$attachments = get_children( array('post_parent' => $id, 'post_status' => 'inherit', 'post_type' => 'attachment', 'post_mime_type' => 'image', 'order' => $order, 'orderby' => $orderby) );

	if ( empty($attachments) )
		return '';

	if ( is_feed() ) {
		$output = "\n";
		foreach ( $attachments as $att_id => $attachment )
			$output .= wp_get_attachment_link($att_id, $size, true) . "\n";
		return $output;
	}

	$itemtag = tag_escape($itemtag);
	$captiontag = tag_escape($captiontag);
	$columns = intval($columns);
	$itemwidth = $columns > 0 ? floor(100/$columns) : 100;

	$selector = "gallery-{$instance}";

	$output = apply_filters('gallery_style', "
		<div id='$selector' class='gallery galleryid-{$id}'>");

	$i = 0;
	foreach ( $attachments as $id => $attachment ) {

		$link = wp_get_attachment_link($id, $size, true, false);

		$link_caption = "<{$captiontag} class='desc'>" . wptexturize($attachment->post_excerpt) . "</{$captiontag}>";

		// splice the caption inside the anchor tag
		$link = preg_replace('|</a>|', $link_caption . '</a>', $link);

		$output .= "<{$itemtag} class='gallery-item imgteaser'>
		";
		$output .= $link;
		$output .= "</{$itemtag}>
		";

		if ( $columns > 0 && ++$i % $columns == 0 )
			$output .= '<br style="clear: both" />';
	}

	$output .= "
			<br style='clear: both;' />
		</div>\n";

	return $output;
}

add_shortcode('gallery', 'tt_gallery_shortcode');
