if (isset($_GET)) 参数未按预期工作 PHP

Question

I have this url

http://localhost/example/products.php/full/grains?name_product=rice&refer_url=index-desktop-sidemenu

ON LIVE SERVER SOMETHING LIKE

http:www.example.com/products.php/full/grains?name_product=rice&refer_url=index-desktop-sidemenu

I am trying to check if $_GET["name_product"] is present with if, but it seems not to detect name_product in the URL when its present.

This is what I tried.

<?php
if (!empty($_GET["name_product"])){ 
    echo $new_tag = $_GET["name_product"];
    echo "Found";
} else {
    echo "Not found";
}
?>

IT always echo not found even when name_product is in the URL as written above.

<?php
if (isset($_GET["name_product"])){  
    echo $new_tag = $_GET["name_product"];
    echo "Found";
} else {
    echo "Not found";
}
?>

Still echo not found even when name_product is in the URL as written above.

EDITED: This is my mod rewrite rule

 Options +FollowSymLinks
RewriteEngine On

RewriteCond %{SCRIPT_FILENAME} !-d
RewriteCond %{SCRIPT_FILENAME} !-f

RewriteRule ^products$ ./products.php
RewriteRule ^index$ ./index.php

RewriteRule ^products/(.*)$ ./products.php?linkcheck=$1&name_product=$2 [NC,L,QSA]

RewriteRule ^404$ ./404.php
RewriteRule ^500$ ./500.php

IndexIgnore *

ADDED products.php to the main file

Answer 1

full/grains?name_product=rice where you are using grains? so do you have any .htaccess file, if it exist then you can use like

#RewriteEngine On
RewriteRule ^([^/\.]+)/([^/\.]+)/?$ /grains.php?name_product=$1&refer_url=$2 [L,QSA]

Let me know if it works but this will change the present structure of the url...

Answer 2

I got it to work

.htaccess
RewriteRule ^products/(.*)$ ./products.php?name_product=$1&refer_url=$2 [NC,L,QSA]

products.php
if (!empty($_GET["name_product"])){ 
echo $new_tag = $_GET["name_product"];
echo "Found";
} else {
echo "Not found";
}
