how to get short url explode work

[vinpkl]

hi all

i want to use explode url for shotening my urls

i have a url like

http://localhost/vineet/products.php?dealer_id=12&category_id=2
 

This is my navigation php code that has url explode function in while statement

<?php 
        $leftqry="select * from dealer_table where category_id=1";
        $leftresult=mysql_query($leftqry);
        if(mysql_num_rows($leftresult)>0)
        {
            while($leftrow=mysql_fetch_array($leftresult))
            {
                $url = 'products.php?dealer_id='. $leftrow['dealer_id'] . "&category_id=" . $leftrow['category_id'];
                list($shorturl) = explode('?', $url);
                //echo $shorturl;
                echo "<tr>";
                echo "<td>" . "<a class='leftnav' href='$shorturl'>" .$leftrow['dealer_name']. "</a></td>";
                  echo "</tr>";
                echo "<tr>";
                echo "<td style='height:1px'><img src='images/left_nav_sep_dwn.gif' alt='' width='147' height='1' /></td>";
                  echo "</tr>";
            }
        }
        ?>
 
 

after url explode function i get the short url as

http://localhost/vineet/products.php
http://localhost/vineet/products.php
http://localhost/vineet/products.php
 

and when i click on these links i am redirected to products.php but i m not able to view the content related to dealer_id and category_id.

there i get

Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in E:\xampp\htdocs\vineet\products.php on line 40
 

otherwise without using this method i m getting all the results fine.

what should i write in "products.php" page so that i can get the result with url explode.

You are not getting a result from your query
@vinpkl
You are not making a DB connection so the last known will be used

Hi.

Lines 8 and 9 in your code make absolutely no sense.
Why compile the link like you do in line 8 using data from your database, only to explode it and essentially strip all the data away?

What exactly do you expect the explode function to do there?

@vinpkl
Nevertheless the error indicates that your result resource is empty.
You should check the validity of the result resource in
$leftresult=mysql_query($leftqry); before proceeding

Sorry mods. My code tags don;t work

If I am not mistaken, the error he posted is from another page.
Most likely caused by the links the explode function is messing up.
The page expects GET parameters that it's not getting.

Heya, vinpkl.

The only way to make what you're trying to do work is to use $url, not $shorturl. There is no way to make those URLs shorter without omitting vital information.

You could try to make pretty URLs using mod_rewrite, though (Easy Mod Rewrite : mod_rewrite tutorial).
