what value does an html form button return?

Recommended Posts

I have a form and this is the HTML:

<input type="submit" name="video" value="preview">

 

so, this means, i think, that there will be a variable called $_POST['video'] and it will be set to the value of "preview"? or, will $_POST['video'] = "TRUE" or something else. I have been wondering about this for a while now and I can't seem to find an answer. Does anyone know? thanks.

set up two pages on your local testing server and try it out, one as the post page and the other with print_r($_POST) on it to tell you what information is passed across

 

sendit.php

<?php
$drinks= array (
'Spring Water'=>'7',
'Coke'=>'6',
'Coffee'=>'4',
'Tea'=>'5',
'Hot Chocolate'=>'8'
);
?>
<html>
<form action="checkit.php" method="post">
<?php
print "<tr><td>Select your drink</td><td><select name='drink'>";
foreach($drinks as $drink=>$price2)
{
print "<option value='$price2'>$drink - R $price2</option>";
}
print "</select>";
<input type="submit" name="Submit" value="Submit" />
</form>
</html>
<?php
?>

 

checkit.php

<?php
print_r($_POST);
?>

Your PHP tag at the bottom was off. Just letting you know.
