Hello

Below a simple order script. If the value is equal to zero there should not be a printing for this item. How? Which is the syntax?

<form action="test.php" method="post">
<input type="text" name="quantity1" value="0" onfocus="if(this.value=='0')this.value=''" size="5" /> item1</p>
<p>
<input type="text" name="quantity2" value="0" onfocus="if(this.value=='0')this.value=''" size="5" /> item2 </p>
<input type="submit" name="submit" value="send" />

php script:

<?php

$quantity1 = $POST['quantity1'];
$quantity2 = $POST['quantity2'];

print "you ordered $quantity1 item1 <br />";
print "you ordered $quantity2 item2";
?>

Example:If I fill out only quantity1 with the value 3 and quantity2 is left empty (value zero)the result should be:
you ordered 3 item1

Thanks

if ($_POST['whatever'] != 0) {
//print content
}

if you're just trying to get it not to print until it's been submitted use isset()

if (isset($_POST['whatever'])) {
//print your stuff
}

Thank you !

I have change it to following:

<?php

$quantity1 = $POST['quantity1'];
$quantity2 = $POST['quantity2'];

if ($POST['quantity1'] != 0) {
print "you ordered $quantity1 item1 <br />";
}
if ($POST['quantity2'] != 0) {
print "you ordered $quantity2 item2 <br />";
}
?>

Thanks again.

If theres an ordernary input you could go for [man]empty[/man].

if (!empty($_POST['quantity1']))
{
   echo "You ordered ".$_POST['quantity1']." 1 item1.";
}
else
{
   //nothing was ordered. 
}

or like i said in the first place, use isset()
