WordPress admin ajax not working correctly
0
I have this PHP page in my WordPress plugin settings page:
<input type="button" class="button button-primary" onclick="update(<?php echo $id; ?>)" value="Done">
This is my JS function which gets called on button click:
function update(id) {
jQuery('.table100 .blockUI').removeClass('invisible');
var data = {
'action': 'update_table',
'id': id
};
var ajaxurl = "<?php echo admin_url( 'admin-ajax.php' ); ?>";
jQuery.post(ajaxurl, data, function () {
}).success(function () {
location.reload();
}).fail(function (data) {
jQuery('.table100 .blockUI').addClass('invisible');
alert('An error occured during the database update!');
});
}
This is the function which should be executed when the js functions gets executed:
add_action( 'wp_ajax_update_table', 'update_table' );
function update_table() {
$id = $_POST['id'];
global $wpdb;
if ( $id > 0 && ! empty( $id ) ) {
$result = $wpdb->update( 'my_table', array( 'xyz' => '1' ), array( 'id' => $id ) );
if ( empty( $result ) ) {
wp_send_json_error( null, 400 );
wp_die();
}
} else {
header( 'HTTP/1.1 500 Internal Server Error' );
header( 'Content-Type: application/json; charset=UTF-8' );
die( json_encode( array(
'message' => 'ERROR. Id missing. Can not update my_table.',
'code' => 1337
) ) );
}
}
All three parts are at the same page and I've tried to trigger it but I'm always getting 400 Bad Request issue. I've added a debug to the PHP function to find out if the function gets called but no result.
My goal:
My goal is it to update a value in the database where id = submitted id.

Chrome and logged in. As i know an access to the admin page is not possible when an admin user is not logged in.

Yeah, you're right. I re-read your question and you did mention that you're doing this on a custom plugin's settings page. I tried your code on a test plugin with a few minor modifications (stripped out some code, like your DB queries) and it worked for me just fine, though. No error 400.

Is it possible that the row in your DB is already correct? From the WP docs: 'Keep in mind that if the $data matches what is already in the database, no rows will be updated, so 0 will be returned. Because of this, you should probably check the return with false === $result'.

So finally I found the problem. I can't add this function on the same page. I moved it to the functions.php and now it works.
