AJAX不在服务器上传递变量（任何AJAX）

Question

So i have a lot of AJAX functions, they worked all well all good in server as well as in localhost until recently i made some changes in the js files and some ajax-php files as well. Nevertheless...they are still working absolutely fine on localhost...but not on server

During debugging, i found out...that the ajax has no problem getting the file....i mean there is no 404 error....however....it isn't passing the variable...

JS FILE

function nextImg(Imgkey){
changeImgViewerN = 0;
var currUrl = window.location.href;
var baseUrl = currUrl.split(/[\\/]/).pop();
var splitUrl = baseUrl.split('&');
var folderKey = splitUrl.pop();
var groupKey = splitUrl[0];
if(groupKey == undefined) groupKey = folderKey;
   $.ajax({
      url:'/9712d9c1_2be4d8c9318e69_1b526557b8_sF',
      type: 'POST',
      data:{searchNextImg:Imgkey, groupKey:groupKey, folderKey:folderKey},
      success: function(response){
        $('#in_folders').prepend(response);
      }
   })
}

PHP FILE

echo "Here";
if(isset($_POST['searchNextImg']) || isset($_POST['searchPrevImg'])) && isset($_POST['groupKey']) && isset($_POST['folderKey'])){

    echo "Reading";
}

However on the server, it just executes echo "Here"; but not echo "Reading";

My .htaccess file says:

RewriteRule ^9712d9c1_2be4d8c9318e69_1b526557b8_sF$ http://www.example.com/ajaxinc/searchFile.php

There are such other AJAX functions but they are not passing variables to the server, however on localhost, they are working perfectly. All of them.

Answer 1

replace:

url:'/9712d9c1_2be4d8c9318e69_1b526557b8_sF',

with

url:'9712d9c1_2be4d8c9318e69_1b526557b8_sF',

You did not pass this variable searchPrevImg in your ajax call, but that is in or condition so does not matter.
suggestion:

use the below way to create data objects:

data:{'searchNextImg':Imgkey, 'groupKey':groupKey, 'folderKey':folderKey},
