Kuitenkin kohdatessani ajaxurl
ei ole määritelty, muutin sitä ajaxurl
joka muodostaa URL-osoitteen alapuolelle
http://example.com/wp-admin/admin-ajax.php?action=get_product_serial_callback
Myös tämä ei auttanut .
Kuinka voin kutsua get_product_serial_callback
-funktion hakemaan JSON
-arvot ja asettamaan nämä arvot function(data)
?

Laita koodi alle _construct () -funktioon ja muuta toiminnan nimi muotoon get_product_serial_callback: –
add_action( "wp_ajax_get_product_serial_callback", array($this,"get_product_serial_callback") ); add_action( "wp_ajax_nopriv_get_product_serial_callback", array($this,"get_product_serial_callback" ));

- Kysymys päivitetty. Se ei edes kutsu funktiota ja palauttaa vastauksena 0
- lisää julkinen funktioon get_product_serial_callback ().
- Esimerkki: public function get_product_serial_callback ()
- WisdmLabs : Kuinka saan Json-tietovasteen funktioon
product_serial_ajax
? Ajaxurl, jonka näen vastauksena, onhttp://example.com/wp-admin/admin-ajax.php?action=get_product_serial
- Sinun tarvitsee vain suorittaa lisäys toiminnon nimellä nimellä ' wp_ajax_get_product_serial ' ja kutsu funktiot kuten edellä on määritelty.

Erillinen JS-tiedosto
function load_product(){ jQuery.ajax({ type: "GET", url: ajaxurl, dataType : "JSON", data : {action: "get_product_serial"}, //cache: false, success: function(data){ alert("Eureka"); } }); }
PS: Seuraavien asettaminen teemani header.php: hen toimi minulle
<script type="text/javascript"> var ajaxurl = "<?php echo admin_url("admin-ajax.php"); ?>"; </script>
array($this, 'get_product_serial_callback')
, kuten anserissa mainitaan.ajaxurl is not defined
