Checkboxes and arrays

[Wolphie]

Ok so,

  If have a group of checkboxes, and I know how to get the values from each of them in an array. However, I can't seem to find a solution to

only return a default value if "none" of the checkboxes are checked, and only return the values that are checked.

 

I've tried:

  foreach($form_values['completed'] as $complete) {
    if($complete != 0) {
      $completed = array();
      $completed = array_push($completed, $complete);
    }
  }
  
  if (is_array($completed)) {
    $completed = implode(', ', $completed);
  }
  else {
    $completed = 'None';
  }

$completed = array();

 

Shouldn't that be declared outside of the foreach statement?

[Wolphie]

Yes it should, thanks for pointing that out for me. Although doing that, I now have another problem. How will I be able to determine whether I should use "None" or not? Since $completed will always return TRUE to being an array.

 

[Andy-H]

Could you use

 

  if ( (count($completed) > 0) ) {
    $completed = implode(', ', $completed);
  }
  else {
    $completed = 'None';
  }

[Wolphie]

OK, now "None" is being set. However, it doesn't seem to get past

 

if($completed != 0) { ... }

 

So no values are being pushed into the array.

Whats the new code you got so far?
