It´s an old thread but i actually had to make some changes to code to achieve this, so i´ll share for future googlers.
With this solution images will be ordered in the order they appear in shortcode
SOLUTION
Search in folder wp-content/responsive-media-gallery/responsive-media-gallery.php
In there you will find a function called “igr_gallery_shortcode”.
1)Add ‘custom_order’ => false, to array passed to extract, around line 132.
2) We add an if clause for using our custom order
if( $custom_order ){
foreach( explode("," , $ids) as $id_img )
{
$attachments[$id_img] = $_attachments[$id_img];
}
}else{
foreach ( $_attachments as $key => $val )
{
$attachments[$val->ID] = $_attachments[$key];
}
}
You will end up with something like this:
function igr_gallery_shortcode($attr)
{
global $post;
$options = get_option('igr_options');
if (isset($attr['orderby']))
{
$attr['orderby'] = sanitize_sql_orderby( $attr['orderby'] );
if ( !$attr['orderby'] )
unset( $attr['orderby'] );
}
extract(shortcode_atts(array(
'orderby' => 'menu_order ASC, ID ASC',
'id' => $post->ID,
'itemtag' => 'dl',
'icontag' => 'dt',
'captiontag' => 'dd',
'columns' => 3,
'size' => 'thumbnail',
'include' => '',
'ids' => '',
'custom_order' => false //parameter added
), $attr));
$count = 1;
$id = intval($id);
if(!empty($ids))
{
$ids = preg_replace( '/[^0-9,]+/', '', $ids );
$_attachments = get_posts( array(
'include' => $ids,
'post_type' => 'attachment',
'post_mime_type' => 'image',
'orderby' => $orderby
)
);
$attachments = array();
//Select if we want to order images like its declared in shortcode
if( $custom_order ){
foreach( explode("," , $ids) as $id_img )
{
$attachments[$id_img] = $_attachments[$id_img];
}
}else{
foreach ( $_attachments as $key => $val )
{
$attachments[$val->ID] = $_attachments[$key];
}
}
//thats all the rest of the function remains the same
Now you can use shortcode in this way:
[gallery ids="576,579,571,572,573,574,578,575,577,580" orderby="none" custom_order="true"]'
