You shouldn’t be sending your data as JSON:
dataType: "JSON"
For add_action("wp_ajax_nopriv_itempricingfunction"
to work, WordPress needs to find the action
parameter in your request, which you’re correctly setting here:
data: {
action : "itempricingfunction",
ean : "EANTEST0101010"
},
The problem is that it checks this using $_REQUEST['action']
, but PHP doesn’t populate $_REQUEST
with JSON. It only works with form data. So remove the dataType
line and you should be fine:
jQuery.ajax(
{
type: 'POST',
url: 'https://www.groupio.fr/wp-admin/admin-ajax.php',
responseType: 'json',
data: {
action: 'itempricingfunction',
ean: 'EANTEST0101010'
},
success: function( data ) {
alert( data );
},
error: function( errorThrown ) {
console.log( errorThrown );
}
}
);
There’s a couple of other things to consider too:
- If the web app is on a different domain, you may run into CORS issues.
- A custom REST API endpoint would be more appropriate for this sort of thing, and does support receiving data as JSON.
