I am trying to perform ajax request in my plugin. What I have done is:
Class Someclass {
public function __construct(){
}
public function current_page_function(){
add_action(
"wp_ajax_test_ajax",array($this,'test_ajax')
);
$this->data=array();
View_Includer::load('index',$this->data,false,false,false,false,true,false,false);
}
public function test_ajax(){
wp_send_json_success('Science achieved!');
exit();
}
}
Script:
var send_ajax_request = function( cpt_id ) {
// Define the function and the data to send to the server.
var data = {
'action': 'test_ajax',
'post_type': cpt_id
};
// Send the request to the server and handle the response.
jQuery.post( Essestials.ajaxurl, data, function( response ) {
return response;
// Handle your response here.
});
};
When I do this, the wordpress return 400 error code. But when I do as below:
Class Someclass {
public function __construct(){
add_action(
"wp_ajax_test_ajax",array($this,'test_ajax')
);
}
public function current_page_function(){
$this->data=array();
View_Includer::load('index',$this->data,false,false,false,false,true,false,false);
}
public function test_ajax(){
wp_send_json_success('Science achieved!');
exit();
}
}
it returns the following response :
{success: true, data: "Science achieved!"}
what wrong am I doing on the first process ? Why it works only when I add the hook in constructor ? Any kind of helps are highly appreciated. Thanks.

Reset to default 0Some actions must be registered as early as possible. When you put it in the "current_page_function" method, (depending on your program) it might be too late.
Hence, the wp_ajax_* hook cannot find your action, and it returns the error.
