GET question

[Anon]

What I am trying to do is go from:

product.php?PageID=$ProductCategory&ProductCategory=$ProductCategory

to

product.php/PageID/ProductCategory/ProductCategory/ProductCategory

which will make it more search engine friendly. I found the code below and cant seem to get it to work.

<?php
$url_array=explode("/",$PATH_INFO);
if (count($url_array)>1)
{
for ($i=1;$i<count($url_array);$i+=2)
{
$name=$url_array[$i];
$value=$url_array[$i+1];
$str='$'.$name.'="'.$value.'";';
eval($str);
}
}
?>

My original script that queries to links:

<?php

Function CategoryList($table_pro = 'Products') {
global $name;
global $value;
$query = "SELECT ProductCategory
FROM $table_pro
GROUP BY ProductCategory";
$result = @($query);
while(list($ProductCategory) =
mysql_fetch_row($result))
print("&nbsp;&nbsp;-&#187;&nbsp;<a href=\"products.php?PageID=$ProductCategory&ProductCategory=$ProductCategory\" class=\"categorylist\">$ProductCategory</a><br>\n");
}
CategoryList()
?>

How would I implement it or where can I find more info on this subject.

Thanks,

Brett

I think $HTTP_GET_VARS is what you\'re wanting to use; it contains an associative array containing all the bits of the query string.

Combining

http://www.php.net/manual/en/configuration.php

with the array function each()

http://www.php.net/manual/en/function.each.php

I get

$path=$PHP_SELF; //The script name
reset($HTTP_GET_VARS);
while(list($key,$val)=each($HTTP_GET_VARS))
{ $path.=\"/$key/$val\";
}

Note that any %xx glyphs will be converted into their corresponding characters, so that \"some%20value\" will appear as \"some value\". Consider putting a urlencode() around your $val to convert them back to %xx form before appending them to $path.
