Help with variables on links

Rulkster

Hi, I am grabbing data from my table and using that data to populate a link inside a string like this:

$sql = "Select * from my_table";
while ($row = mysql_fetch_array($result)){
$Nav = $row['last_name'];

$display_form .= <a href=modify.php?sel=$Nav>$Nav</a>
<form method=post action=add.php?sel=$Nav>
.
.
.
"; }

Now everything works fine if $Nav is only one word, but if $Nav is two words or more (spaces), it does not work. I tried doing this:

and this:

But it doesn't work. What do I have to do here? By the way, I can not strip the spaces from $Nav because I need to use it as is when the script loads after clicking the link or hitting the form submission button.

Thanks for any help

I would set use the id in the link and nav as the text, then you can requery based on the ID, however it you really want to use nav then do this:

<?php
$sql = "Select * from my_table"; 
while ($row = mysql_fetch_array($result)){ 
$Nav = $row['last_name']; 
$url_nav = str_replace(' ','_',$Nav);
$display_form .= <a href=modify.php?sel=$url_nav >$Nav</a>; 
<form method=post action=add.php?sel=$url_nav> 
. 
. 
. 
"; }
?>

then when you read it back in after they click do this

<?php
$in_nav = str_replace('_',' ',$_POST['sel']);
?>

Thanks, I am going to try that.

I am actually passing not only 1 variable ($Nav) but 8 variables back to the same script (i put modify.php and add.php as the link to make it easier to read the post) The script is actually calling itself, passing the variables to itself.

Thanks again
