checkbox question

[Dillenger]

How do I check if a checkbox is checked or not in PHP?

I would like to do an if statement, that does one thing if the box is checked and another if the box is not.

Thanks

A checkbox returns TRUE if checked and FALSE if unchecked, so:

if($_POST['checkbox']) {
     echo "The checkbox is checked.";
} else {
     echo "The checkbox is unchecked.";
}

this is good, thanks, but how would I do it for multiple checkbox's? I have 3 in this form.

If the checkboxes have the same name then you will have to set it up as an array. If they have seperate names then you can take what Merve gave you and use it three times.

$a = $_POST['a']; 
$b = $_POST['b']; 
$c= $_POST['c']; 

if(empty($a) || empty($b) || empty($c)) 
{ 
echo "I'm sorry, you did not fill out all the required information"; 
if(empty('$a')) 
{ 
echo "A is required!"; 
} 
if(empty('$b')) 
{ 
echo "B is required!"; 
} 
if(empty('$c')) 
{ 
echo "C is required!"; 
} 
include("page.php"); 
exit(); 
} 
else 
{ 
echo "<font color=red><b>You clicked all the checkboxes. THANK YOU!</b></font>"; 
}

This has just helped me as well. See what a search of the archives can do for you? 😉

Thanks!
