PHP redirect URL

Question

I have successfully directed my users to a page that contains their information from a table. Using this code:

<?php foreach ($customers as $row) : ?>
<td onclick="window.location='view_customer.php?customer_id=<?php echo $row['id'] ?>&operation=edit';"> 
</td>                    
<?php endforeach; ?>     

Now they are on view_cutomer.php. The next step would be to redirect the users to another page that also contains their information (the same information). Using a button. The next page is paint.php. I've tried this code, but it does not seem to work. Btw this next page no longer has a table.

 <button onclick="window.location='paint.php?customer_id=<?php echo $row['id'] ?>&operation=edit';" class="rbutton">Paint</button> 

How do i redirect users to a specific page using their ID?

Answer 1

on the 2nd page the id you want is in the get array (from the url)

<button onclick="window.location='paint.php?customer_id=<?php echo $_GET['customer_id'] ?>&operation=edit';" class="rbutton">Paint</button>
