Question about form in PHP and MySQL

[peter_ross@canada.com]

Hi,

I am new to PHP and MySQL. I was writing a script to pull data from
SQL server and display the data. There's a "submit" button. When the
user clicks "submit", the form calls itself and I "expect" the submit
value is set. However, I find the $submit is never set. Is there
something wrong with my script?

Thanks,
Ross

<?php
include("conten tdb.php");
$display = mysql_query("SE LECT * FROM $table ORDER BY id",$db);

if (!$submit) {
echo "<form method=post action=$PHP_SEL F>";

// code to display questions

echo "<input type='submit' value='SUBMIT' name='submit'>" ;
echo "</form>";
}

if ($submit) {
// calculate scores
}
?>

Use $_POST['submit'], not $submit .
'register_globa ls' is evil.
