Excluding a specific image from get_children according to its order number ?

  • Hi,

    I use the following function in functions.php to output all images of a post’s gallery:

    <?php
function my_attachment_image($postid=0, $size='large', $attributes='') {
	if ($postid<1) $postid = get_the_ID();
	if ($images = get_children(array(
		'post_parent' => $postid,
		'post_type' => 'attachment',
		'numberposts' => -1,
		'orderby' => 'menu_order',
		'post_mime_type' => 'image',)))
		foreach($images as $image) {
			$attachment=wp_get_attachment_image_src($image->ID, $size);
			?><a href="<?php echo $attachment[0]; ?>" <?php echo $attributes; ?> rel="fancybox-<?php echo $postid; ?>">&nbsp;</a><?php
		}
}?>

    The only thing missing from this function for me right now it the ability to exclude a specific image. That specific image would be the one with number 1 manually specified in the order field of the gallery.

    I tried adding this with no luck:

    ‘exclude’ => ‘1’,

    Many thanks for your time and help.

  • Maybe this will work

    $to_exclude = 3;
$i = 1;
foreach($images as $image) {
$attachment=wp_get_attachment_image_src($image->ID, $size);
if( $i != $to_exclude ){
?><a href="<?php echo $attachment[0]; ?>" <?php echo $attributes; ?> rel="fancybox-<?php echo $postid; ?>">&nbsp;</a><?php
}
$i++
}

    I get syntax error

    <?php
function my_attachment_image($postid=0, $size='full', $attributes='') {
	if ($postid<1) $postid = get_the_ID();
	if ($images = get_children(array(
		'post_parent' => $postid,
		'post_type' => 'attachment',
		'numberposts' => -1,
		'orderby' => 'menu_order',
		'exclude' => '1',
		'post_mime_type' => 'image',)))
		$to_exclude = 1;
		$i = 1;
		foreach($images as $image) {
			$attachment=wp_get_attachment_image_src($image->ID, $size);
			if( $i != $to_exclude ){
			?><a href="<?php echo $attachment[0]; ?>" <?php echo $attributes; ?> rel="fancybox-<?php echo $postid; ?>">&nbsp;</a><?php
		}
		$i++
}?>

    Could you guide me please ?

    $i++;
