AJAX POST 请求与 .htaccess 重定向规则一起无法正常工作

Question

This is my .htaccess file. As it can be seen everything is redirected through index.php.

<IfModule mod_rewrite.c>
  Options -Multiviews
  RewriteEngine On
  RewriteBase /project_name/public
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteRule  ^(.+)$ index.php?url=$1 [QSA,L]
</IfModule>

Now this is a file (viewname.php) located in one of my views folder (this is a MVC styled project). Here as it can be seen I am making an AJAX POST request, to a file ajax.php located in the same folder as index.php (ie, folder public). Notice that I'm not writing the url as "../something", as I'm redirecting everything through index.php. I confirmed that by writing <?php echo __FILE__;?> , in this file, which returned the result index.php. If the AJAX request is successful, I should get the output as "Working" in the div with id 'r'. But that does not happen. Also I do not get any error like jquery.min.js:4 POST http://127.0.0.1/project_name/public/file_name.php 404 (Not Found) in the console, which I used to get in a project without that .htaccess file. When I console.log(data) I see the HTML code in the index.php file, which in this case are CDNs for Bootstrap and JQuery, in the console. What changes should I make to my AJAX code or .htaccess file?

<div id="r"></div>

//JQuery AJAX
$(document).ready(function(){
 $.ajax({
  url: "ajax.php",
  method: "POST",
  data: {
   valid: "yes"
  },
  success: function(data){
  $("div#r").html(data);
  }
 });
});

This is the code in the ajax.php file:

<?php
if(isset($_POST['valid'])){
 if($_POST['valid']=='yes'){
  echo 'Working';
 }
}

Answer 1

you missing function after ()(round bracket)

$(document).ready(function(){
         $.ajax({
          url: "test1.php",
          method: "POST",
          data: {
           valid: "yes"
          },
          success: function(data){
          $("div#r").html(data);
          }
         });
    });

Here in this case the AJAX works completely but the only difference is that the ajax cannot make a difference to your webpage like echo,call the function,etc.

Answer 3

I changed the url from "ajax.php" to " http://127.0.0.1/project_name/ajax.php ", and everything is working fine now.
