I'm trying to send a variable to the server, using XMLHttpRequest.



I tested it on local on a non-Wordpress file and it works. But on production, on my Wordpress file, the onreadystatechange AJAX status doesn't get to 200.



Is there anything I need to be aware when XMLHttpRequesting in Wordpress?



I have the following code for sending data to the server using XMLHTTP Request but it's not working I don't know why? I'm getting the following error:



VM704:1 POST http://localhost/amt/wp-admin/admin-ajax.php 400 (Bad Request)



here is my WordPress code:



add_action('wp_ajax_csv_file', 'csv_file');

add_action('wp_ajax_nopriv_csv_file', 'csv_file');

function csv_file()
{
if($_POST['rtype'] == 'enr_data'){
set_time_limit(0);
ob_implicit_flush(true);
ob_end_flush();

for ($i = 0; $i < 10; $i++) {
//Hard work!!
sleep(1);
$p = ($i + 1) * 10; //Progress
$response = array('message' => $p . '% complete. server time: ' . date("h:i:s", time()),
'progress' => $p);

echo json_encode($response);
}

sleep(1);
$response = array('message' => 'Complete',
'progress' => 100);

echo json_encode($response);

die();
}
}





function ajax_stream() {
if (!window.XMLHttpRequest) {
alert("Your browser does not support the native XMLHttpRequest object.");
return;
}
try {
var xhr = new XMLHttpRequest();
xhr.previous_text = '';
xhr.responseType = "text";

    Did you declare the ajaxurl var properly?? I don't see it declared in your code

  • Did you try to run it after clearing your cache?

  • @Rafsun Chowdhury, Yes it's correct did you see the Error text added above. that's the url: localhost/amt/wp-admin/admin-ajax.php

  • It's hard for me to understand the goal here. At the very least I can say you should be validating each request with a nonce within the PHP.

  • @GFargo I just has 400 error this means the request is not sent to the server side.

    Did you declare the ajaxurl var properly?? I don't see it declared in your code

  • Did you try to run it after clearing your cache?

  • @Rafsun Chowdhury, Yes it's correct did you see the Error text added above. that's the url: localhost/amt/wp-admin/admin-ajax.php

  • It's hard for me to understand the goal here. At the very least I can say you should be validating each request with a nonce within the PHP.

  • @GFargo I just has 400 error this means the request is not sent to the server side.
