calculating checkboxes

[Nat]

hi! Was wondering if anyone could help me with this problem.

 

I have made a form consisting of an array of seven checkboxes. I'm trying to figure out how to write a php script to calculate 1 dollar for every checkbox chosen.

Have you got any code you can show us?

As Hughesy1986 suggested, seeing some of your code would be helpful, but for now let's assume you have a form looking somewhat like this:

 

<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="POST">
<input type="checkbox" name="checkboxes[]" value="CheckBox 1">
<input type="checkbox" name="checkboxes[]" value="CheckBox 2">
<input type="checkbox" name="checkboxes[]" value="CheckBox 3">
<input type="checkbox" name="checkboxes[]" value="CheckBox 4">
<input type="checkbox" name="checkboxes[]" value="CheckBox 5">
<input type="checkbox" name="checkboxes[]" value="CheckBox 6">
<input type="checkbox" name="checkboxes[]" value="CheckBox 7">
<input type="submit" name="submit" value="Submit!">
</form>

 

You could check how many checkboxes were checked simply by doing something like this:

 

<?php
if($_POST['submit']){
$boxes_checked = count($_POST['checkboxes']);
echo 'You clicked '.$boxes_checked.' box(es). You get $'.$boxes_checked.'!';
}
?>
