PHP Enhancing a Simple PHP Application Cleaning URLs with Rewrite Rules Get Variables and Rewrite Rules

Trouble with .htaccess file. Cannot get to detail shirt page after modifying rewrite rules.

I am using Netbeans and XAMMP on this project. The source folder is shirts4mike. So the URL is localhost/shirts4mike.

As shown in the video, I tried to get to the detail shirt page by typing localhost/shirts4mike/shirts/108/.

Instead it takes me to "MIKE’S FULL CATALOG OF SHIRTS" page (localhost/shirts4mike/shirts/). The URL still reads localhost/shirts4mike/shirts/108/ even with 102, 103, or 104 at the end etc. Doesn't matter what shirt I click, it will always end in "MIKE’S FULL CATALOG OF SHIRTS" page with the shirt id number at the end of the URL.

I thought there was something wrong with shirt.php or products.php. I downloaded the project file and paste and overwrite all my original files except .htaccess and config.php. The result is still the same above.

My config.php is read:

<?php
    define("BASE_URL", "/shirts4mike/");
    define("ROOT_PATH", $_SERVER["DOCUMENT_ROOT"] . "/shirts4mike/"); 
?>

I think there might something wrong with my .htaccess file. The code/rules for it is:

RewriteEngine On
RewriteBase /shirts4mike
RewriteRule ^shirts/$ /shirts4mike/shirts/shirts.php
RewriteRule ^shirts/([0-9]+)/$ /shirts4mike/shirts/shirts.php?id=$1

Wait wait wait wait wait - relax - I think this is a simple typo.

I'm going on the assumption that you have two files - shirts.php to show many shirts and shirt.php to show a single shirt.

This is your code:

RewriteEngine On
RewriteBase /shirts4mike

#rule 1
RewriteRule ^shirts/$ /shirts4mike/shirts/shirts.php

#rule 2 - should this say shirt.php instead of shirts.php?
RewriteRule ^shirts/([0-9]+)/$ /shirts4mike/shirts/shirts.php?id=$1

in rule 1, you're saying anything that looks like this: "shirts/" should be rewritten to "/shirts4mike/shirts/shirts.php". This is where you're showing many shirts. This looks fine.

in rule 2, you're saying anything that looks like "shirts/([0-9])" should be rewritten to "/shirts4mike/shirts/shirts.php?id=$1". But this is the page where you're showing many shirts (shirts.php). Surely you want to redirect to shirt.php, which is your page is display a single shirt.

In both rules you're rewriting to

shirts.php

But I think rule 2 should rewrite to

shirt.php

notice the missing 's'!!

Therefore rule 2 should be:

RewriteRule ^shirts/([0-9]+)/$ /shirts4mike/shirts/shirt.php?id=$1

Hmm.. It would seem that you're redirecting both /shirts/ and shirts/1/ to shirts.php

Should shirts/1/ not redirect to shirt.php?

I'm not sure you what you're implying. What I am trying to do is to create clean URL for the detail shirt page. Each detail shirt has its own id number in the array and is identified by shirt.php?id=id_number. For example if you click a shirt that has the id of 108. The URL would be localhost//shirts4mike/shirts/shirt.php?id=108 . With the clean URL it should be localhost//shirts4mike/shirts/108/ . If you check the lesson video(Get Variables and Rewrite Rules) under Cleaning URLs with Rewrite Rules , you'll know what I mean. The trouble is that when I click any shirt with id=108 it takes me to localhost/shirts4mike/shirts/ but with URL ocalhost//shirts4mike/shirts/108/ .

Here are the PHP files with segment of codes which I believe that might be the culprit. I still wouldn't over look .htaccess and config.php mentioned above.

1/ products.php 

<?php

function get_list_view_html($product_id, $product) {

    $output = "";

    $output = $output . "<li>";
    $output = $output . '<a href="' . BASE_URL . 'shirts/' . $product_id . '/">';
    $output = $output . '<img src="' . BASE_URL . $product["img"] . '" alt="' . $product["name"] . '">';
    $output = $output . "<p>View Details</p>";
    $output = $output . "</a>";
    $output = $output . "</li>";

    return $output;
}

2/ index.php(main file of the source folder)

<?php include(ROOT_PATH . "inc/products.php"); ?>
                <ul class="products">
                    <?php 

                        $total_products = count($products);
                        $position = 0;
                        $list_view_html = "";
                        foreach($products as $product_id => $product) { 
                            $position = $position + 1;
                            if ($total_products - $position < 4) {
                                $list_view_html = get_list_view_html($product_id,$product) . $list_view_html;
                            }
                        }
                        echo $list_view_html;
                    ?>                              
                </ul>

3/shirts.php

pageTitle = "Mike's Full Catalog of Shirts";
$section = "shirts";
include(ROOT_PATH . 'inc/header.php'); ?>

        <div class="section shirts page">

            <div class="wrapper">

                <h1>Mike&rsquo;s Full Catalog of Shirts</h1>

                <ul class="products">
                    <?php foreach($products as $product_id => $product) { 
                            echo get_list_view_html($product_id,$product);
                        }
                    ?>
                </ul>

            </div>

That's lots of codes posted, but I am totally lost and cannot continue further with the project, unless the bug is fixed. Hopefully Randy will stumble on my post and offer me the solution. But any PHP ace will do.
