php get method unreachable in xampp - php

Question

I've been trying to figure this out for hours, but haven't been able to get anywhere. There are so many questions asked in stackoverflow, and I've tried almost all of them, but still haven't been able to figure out what the problem is that I'm having.
I'm working on a project for my Master's thesis for which I have to perform some data analysis. I'm building a site using php, backbone, and mongodb. I'm using xampp, and this is my directory structure:
htdocs
|-MyProject
|------API
|---Slim
|---index.php
|------scripts
|-------App
|----Collections
|----Models
|----Views
|-------lib
|-index.html
The index.html is the boilerplate html stuff and calls backbone collections and views. The index.php within the directory API instantiates slim and has GET method.
Here's the index.php
<?php
echo 'test';
require 'Slim/Slim.php';
\Slim\Slim::registerAutoloader();
use Slim\Slim;
$app = new Slim();
$app->get('/trends', 'getTrends');
and my backbone collections
App.Collections.TrendsCollection = Backbone.Collection.extend({
model : App.Models.TrendModel,
url : "API/trends",
initialize: function(){
console.log('collections');
}
});
I read that I may need to set RewriteRule, so I tried this:
Options +FollowSymlinks
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ /API/index.php [R,NC]
but this didn't find the method I'm trying to reach either. I've been trying to figure this out for too long, and I'm pressing for time. Can someone please give me some guidance?
EDIT:
function getTrends(){
echo 'Hello';
}

Answer 1

I think your problem is in getTrends function. Show me that function.

Answer 2

After hours of trying to figure it out, I finally realized that the rewrite rules should be in .htaccess in the same directory as index.php. It finally worked.
