I am trying to create a shortcode with an array as input like so

function product_gallery_shortcode($atts) {

extract(shortcode_atts(array(
            'product_id' => '31',
            'prodvid' => false,
            'youtubeids'=>'',//['lbRqMddP2jo','eFAxx817rC0'],
            'thumbnr' =>2
                ), $atts));

I like to loop throught the youtube id's but i don't know how to initialize the youtubeids as an array

so it reads

    'youtubeids'=> array('lbRrePOP2jo','eFAxx17rC0'),

regards

• 2 I'm sorry, but I don't understand what you goal is. Could you elaborate? Currently the variable $youtubeids holds that array... – kaiser Commented Mar 5, 2013 at 11:49
• @kaiser, well when i use the shortcode the values i passes into youtubeids didn't work as an array in my shortcode function. So i had to turn the values into an array again, see my answer – alex Commented Mar 5, 2013 at 12:16

Ok found a solution

function product_gallery_shortcode($atts) {
extract(shortcode_atts(array(
            'product_id' => '31',
            'prodvid' => false,
            'youtubeids'=> '',
            'thumbnr' =>2
                ), $atts));
etc

and i had to turn youtubeids into an array again

$youtubeidsnew = array();
$youtubeidsnew = explode(',', $youtubeids);

I found the best solution for this problem. If you want use array for input of shortcode use this:

function product_gallery_shortcode($atts) {
    extract(shortcode_atts(array(
                'product_id' => '31',
                'prodvid' => false,
                'youtubeids'=> array(),
                'thumbnr' =>2
                    ), $atts));
    etc 
    $youtubeids = $atts[youtubeids];
    $youtubeids = explode(',', $youtubeids);

In your shortcode input you can use the following for each array index:

[myshortcode youtubeids="index0,index2,index3"]

Simple way I use:

[my param="key1=value1&key2=value2"]

in shortcode callback, just do:

parse_str( str_replace("&", "&", $attrs['param']), $array);
// var_dump( $array );

Could you not just do:

extract(shortcode_atts(array(
            'product_id' => '31',
            'prodvid' => false,
            'youtubeids'=>array('lbRrePOP2jo','eFAxx17rC0'),
            'thumbnr' =>2
        ), $atts));
