parameter passing

[harry_k]

Hello

I am still having difficulty with basic parameter passing between pages, e.g. start.php and finish.php

If start.php passes a parameter RATING to a query in finish.php using a form

start.php

<form action="http://localhost/finish.php" method="post" target="_blank">
Rating: <input type="text" name="rating" value="<?=$rating?>"><br>
<input type="submit" value="Get Query">

finish.php

$sql = "SELECT * FROM TABLE where rating > ";
$sql .= $HTTP_POST_VARS["rating"];

then query works when button is pressed.

If start.php passes a parameter RATING to a query in finish.php using external link

start.php

<a href="http://localhost/finish.php?rating=5">finish></a>

finish.php

$sql = "SELECT * FROM TABLE where rating > $rating";

then $rating never initializes and query fails.

Thanks for response

Harry

The first way you did it (the one that works) uses POST.

The second uses GET, so your HTTP_POST_VARS doesn't work with the href.

Thanks for the reply. Does GET work with parameters?

Even if I try to launch finish.php using hardcoded value http://localhost/finish.php?rating=5 in the IE address bar the $rating never get initialized and query fails.

$sql = "SELECT * FROM TABLE where rating > $rating";

This forum page uses similiar syntax and it works.

It works now. The problem was a setting in php.inp. Default is 'register_globals = Off', should be 'register_globals = On'
