PHP Question

.htaccess won't stop rewriting when ajax request is made

Hello I'm having great difficulty making it so .htaccess will stop rewriting the url in a ajax call..

my .htaccess below:

DirectoryIndex index.php

RewriteEngine on

RewriteCond %{REQUEST_FILENAME} !-s
RewriteCond %{HTTP:X-Requested-With} !=XMLHttpRequest
RewriteRule ^([^/\.]+)/?$ index.php?system=$1
RewriteRule ^([^/\.]+)/([^/\.]+)/?$ index.php?system=$1&task=$2
RewriteRule ^([^/\.]+)/([^/\.]+)/([^/\.]+)/?$ index.php?system=$1&task=$2&id=$3
RewriteRule ^([^/\.]+)/([^/\.]+)/([^/\.]+)/([^/\.]+)/([^/\.]+)/?$ index.php?system=$1&task=$2&id=$3&data=$4&key=$5


and the PHP ajax call:

<script>
$(document).ready(function () {
$(".checkButton").click(function () {
var objID = this.id;
$.ajax({
url: "/update.php",
type: 'POST',
data: {val: objID},
success: function (data, textStatus, jqXHR)
{
alert("sucess" + data);
},
error: function (jqXHR, textStatus, errorThrown)
{
alert(textStatus + errorThrown + jqXHR);


}
});
});
});




Because of an existing large amount of code I don't want to change the rewrite rules we have in place already but find a way in which I can ignore the rewrite rules for only a ajax request. I have been searching around for a while and I only managed to find suggestions of using

RewriteCond %{REQUEST_FILENAME} !-s
RewriteCond %{HTTP:X-Requested-With} !=XMLHttpRequest


edit:

RewriteCond %{REQUEST_FILENAME} !-s
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{HTTP:X-Requested-With} !=XMLHttpRequest
RewriteRule ^([^/\.]+)/?$ index.php?system=$1
RewriteRule ^([^/\.]+)/([^/\.]+)/?$ index.php?system=$1&task=$2
RewriteRule ^([^/\.]+)/([^/\.]+)/([^/\.]+)/?$ index.php?system=$1&task=$2&id=$3
RewriteRule ^([^/\.]+)/([^/\.]+)/([^/\.]+)/([^/\.]+)/([^/\.]+)/?$ index.php?system=$1&task=$2&id=$3&data=$4&key=$5


Revised .htaccess ajax is still unable to find the page after testing.

Answer

RewriteCond works just for the first RewriteRule just after.

Use instead:

# skip all files and directories from rewrite rules below
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d [OR]
RewriteCond %{HTTP:X-Requested-With} =XMLHttpRequest
RewriteRule ^ - [L]

RewriteRule ^([^/.]+)/?$ index.php?system=$1 [L]
RewriteRule ^([^/.]+)/([^/.]+)/?$ index.php?system=$1&task=$2 [L]
RewriteRule ^([^/.]+)/([^/.]+)/([^/.]+)/?$ index.php?system=$1&task=$2&id=$3 [L]
RewriteRule ^([^/.]+)/([^/.]+)/([^/.]+)/([^/.]+)/([^/.]+)/?$ index.php?system=$1&task=$2&id=$3&data=$4&key=$5 [L]
