[Resolved] Checkbox Post data

barrin

I know this question doesn't directly pertain to PHP, but I'm using the information in a PHP script, so I hope it's cool.

I have a form, and on this form are 3 checkboxes, let's call 'em A, B, and C, all with the name attribute set as "checkbox", and their value attributes set at A, B and C, respectively.

After I submit my form, I have a line that will echo this information:

echo $_POST['checkbox'];

This only returns one of the checkboxes, though. If A, B, and C are checked, it will echo only "C".

How do you make it echo all checked boxes? Is there some sort of array? 😕

I think you might have to do this one the old fasion way.

You will need to have each checkbox have it's own name.

Then

echo $POST['checkbox1'];
echo $POST['checkbox2'];
echo $_POST['checkbox3'];

Now, if you had too many check boxes and you didn't want to have to manually write out each one, i think this would work:

for ($i = 0; $i > 10; $i++) {
$variable = $_POST['checkbox$i'];
echo "$variable" ;
}

I think that should work.

Of course, you would just need to name each of your checkboxes "checkbox1, checkbox2, etc...).

Then put the number of check boxes in your greater than statement. The above example would get 10 values...

add [] to name of control to get array:

<INPUT TYPE="CHECKBOX" NAME="checkbox[]" VALUE="A">
...

Thanks for the help, guys. I just used the old-fashioned way, and since I only have 3 boxes, I used a couple of these:

      if( isset( $a ) ) {
         if( $a == 'yes') {
            $a = 'on';
         } else {
            $a = "off";
         }
      } else {
         $a = "off";
      }

Thanks for that site, as well. It solved another problem I had regarding coordinates in image buttons. Didn't realize PHP converted the '.'s to '_'s.
