writting a loop that uses the url for condition

[fzx5v0]

I wonder if anyone can help

i am not very good with php and have a problem that I need some input into

I would like to right a loop or some conditions that say if the url has product_info in it use this code

<title><?php echo $the_product_name; ?></title>
<meta name="keywords" content="<?php echo $the_product_name; ?>, <?php echo $the_product_model; ?>, <?php echo $the_manufacturers['manufacturers_name']; ?>">
<meta name="description" content="<?php echo $the_product_description . "," . $the_product_name; ?>">

if it does not then use this code

<?php

if (file_exists(DIR_WS_INCLUDES . 'meta_tags.php')) {
require(DIR_WS_INCLUDES . 'meta_tags.php');
} else {
?>
<title><?php echo TITLE ?></title>
<?php
}

?>

Can anyone help or advise

Thanks in advance

i don't understand the question. are you looking for a specific GET variable on the URL query string? if so then it will be in the $GET array.

if (isset($_GET['product_info']))
{
	// do something if product_info is set
}
