Wordpress Admin Ajax 400 (Bad Request) - php

Question

I have used Wordpress Admin Ajax and the console shows that 400 (Bad Request)
jQuery('#submitid').click(function(e){
e.preventDefault();
//var newCustomerForm = jQuery(this).serialize();
jQuery.ajax({
type: "POST",
url: "wp-admin/admin-ajax.php",
data: {status: 'status', name: 'name'},
success:function(data){
jQuery("#result").html(data);
}
});
});

Answer 1

The Wordpress AJAX process has some basic points that should be followed if you want it to work correctly:
1.In functions.php add the action you'd like to call from the frontend:
function logged_in_action_name() {
// your action if user is logged in
}
function not_logged_in_action_name() {
// your action if user is NOT logged in
}
add_action( 'wp_ajax_logged_in_action_name', 'logged_in_action_name' );
add_action( 'wp_ajax_nopriv_not_logged_in_action_name', 'not_logged_in_action_name' );
2.Register the localization object in functions.php
// Register the script
wp_register_script( 'some_handle', 'path/to/myscript.js' );
// Localize the script with new data
$some_object = array(
'ajax_url' => admin_url( 'admin-ajax.php' )
);
wp_localize_script( 'some_handle', 'ajax_object', $some_object );
// Enqueued script with localized data.
wp_enqueue_script( 'some_handle' );
3.Create the AJAX request on the frontend
// source: https://codex.wordpress.org/AJAX_in_Plugins
var data = {
'action': 'not_logged_in_action_name',
'whatever': 1234
};
jQuery.post( ajax_object.ajax_url, data, function( response ) {
console.log( response );
}

All Wordpress Ajax call must have action param which points to hook wp_ajax_{action_param} or wp_ajax_nopriv_{action_param} and from there you jump to function from that hooks.
From Codex:
add_action( 'wp_ajax_my_action', 'my_action' );
add_action( 'wp_ajax_nopriv_my_action', 'my_action' );
function my_action() {
$status = $_POST['status'];
}

Answer 3

first you shouldn't write the url by yourself. You could use the localize function to add the url to your javascript file:
wp_enqueue_script('myHandle','pathToJS');
wp_localize_script(
'myHandle',
'ajax_obj',
array( 'ajaxurl' => admin_url( 'admin-ajax.php' ) )
);
After this you can use ajax_obj.ajax_url within your script to receive the url.
Second, did you implement the correct hook?
// Only accessible by logged in users
add_action( 'wp_ajax_my_action', 'my_action_callback' );
// Accessible by all visitors
add_action( 'wp_ajax_nopriv_my_action', 'my_action_callback' );
