Question

I'd like to change the type of input field from text to numbers only.I've tried as following

<?= form_input('num', '','class="form-control" id="num", type="number"');?>

but not working

Answer 1

Try this one for numeric input:

$data = array(
  'name' => 'num',
  'id'   => 'num',
  'class'=> 'form-control',
  'type' => 'number'
);

echo form_input($data);
