Rewrite URLs in RESTful API - php

Question

I have to create an API in PHP, which I have never done before. I have a index.php in my root folder which contains a form. A button click activates an AJAX Request to read all entries and a form can be filled out to send data. I will also have DELETE and update.
ajaxcall.js
// GET to retrieve
var req;
req=new XMLHttpRequest();
req.open("GET", 'src/api/v1/posts',true);
req.send();
//post with ajax
$.ajax({
type:"POST",
url: "src/api/v1/posts",
data: test,
ContentType:"application/json",
success:function(){
alert('successfully posted');
},
error:function(){
alert('Could not be posted');
}
});
I have a folder src/api/v1 in there I want the endpoint file api.php which handles the different requests. I now need all the AJAX calls to be resend to api.php which sits inside that v1 folder. I created an .htaccess which is stored in also stored in src/api/v1. I added the following:
.htaccess
<IfModule mod_rewrite.c>
Options +FollowSymLinks
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule src/api/v1/(.*)$ src/api/v1/api.php?request=$1 [QSA,NC,L]
Unfortunately I get a 404 not found, it just does not seem to re-write the URL to the api.php so it is looking for /posts which does not exists. What am I doing wrong?

Answer 1

Actually you should store the .htaccess on the root directory, otherwise Apache will not know that there's an .htaccess under /src/api/v1, so apache will look for the directory src/api/v1/posts and as is it's not found a 404 error will be returned.
<IfModule mod_rewrite.c>
Options +FollowSymLinks
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule src/api/v1/(.*)$ /src/api/v1/api.php?request=$1 [QSA,NC,L]
</IfModule>
