php - Adding multiple products to Woocommerce basket script -

i have little html product selector passes woocommerce sku's via post data in url. want use these sku's add matching products woocommerce shopping cart.

i have written php script sitting in wordpress theme directory think there little why getting "500 server error". if remove add_to_cart function , echo out sku's instead works see problem there. thought because using add_to_cart function outside of loop? not sure. below have far if out appreciated.

    <?php    //get skus   $design_sample_ids = $_get["samples"];    //put skus in array   $design_sample_id = explode(";", $design_sample_ids);    //loop through skus   foreach ($design_sample_id $sample_id) {      //add each sku cart     wc()->cart->add_to_cart($sample_id);  }  ?> 

ok have cobbled solution works me. may not best i'm still interested see others can come with. posting here in case helps anyone.

in functions.php file..

    function add_multiple_sku($design_space_sample_skus) {    global $woocommerce;    //put skus in array   $design_space_sample_sku = explode(";", $design_space_sample_skus);    //loop through array of skus   foreach ($design_space_sample_sku $sample_sku) {      //convert skus product ids        $sample_id = wc_get_product_id_by_sku( $sample_sku );        //add each product id cart      wc()->cart->add_to_cart( $sample_id );    }    //redirect cart   $cart_url = $woocommerce->cart->get_cart_url();   wp_safe_redirect( $cart_url );  } 

then function needs calling somewhere , sku's pulling in. have created file in theme directory , used following. sku's posted file post data. again, may not best solution.

 $parse_uri = explode( 'wp-content', $_server['script_filename'] ); require_once( $parse_uri[0] . 'wp-load.php' );  //add multiple skus  $design_space_sample_id = $_get["samples"];  add_multiple_sku($design_space_sample_id);
