从 ajax 调用在后台执行 php 页面

Question

I have this tab.php page that is basically the index of the site. It contains all JavaScript and HTML code.

I'm trying to send some array from this page to a PHP page and than do an update query, uploading the array on my phpmyadmin.

I used this code in tab.php but it doesn't work.

 var send_array = {
"red": redtruppe,
"blue": bluetruppe,
"orange": orangetruppe,
"purple": purpletruppe,
"black": blacktruppe,
"green": greentruppe
};

$.ajax({ 
   type: "POST", 
   url: "send.php", 
   data: { TruppeJson : send_array }, 
   success: function() { 
          alert("Success"); 
    } 
}); 

the send.php page is, for now, something like this:

<?php
$myTruppe = json_decode($_POST['TruppeJson']);
echo '<script>console.log('.$myTruppe.')</script>';
?>

The success alert seems to work, but the send.php apparently not, any suggestions?

Answer 1

Try to use that for the data:

 JSON.stringify(send_array)

and define your dataType as JSON

dataType: "json"

Would look like this:

$.ajax({ 
   type: "POST", 
   url: "send.php", 
   data: JSON.stringify(send_array),
   dataType: "json",
   success: function() { 
          alert("Success"); 
    } 
}); 

As you stated, success is getting called. So your data is not just been sent to the backend.
