form validation for NOT matches - El Forum - 01-19-2010

[eluser]blorriman[/eluser]
I have a form and I am using the following to create an input:
echo form_input('first_name', set_value('first_name', 'enter first name'));

I then validate the form:
$this->form_validation->set_rules('first_name', 'Name', 'trim|required');

However, because the form opens with "enter first name" in the text input, the required validation doesn't work.

I like the look this way instead of adding a label, but how do I validate this as required now?

There are one of two options.

You can use placeholder='Enter First Name'
which looks similar, but has a default value of ""

Or do a client side validation on submit that the form doesn't contain "enter first name" in the first name field

Thanks JHackaMack,
I tried :
$name = 'enter name';
echo form_input('first_name', set_value('first_name', $name));

but it's still not validating

Try This
Code:
$data = array(
              'name'        => 'first_name',
              'id'          => 'first_name',
              'placeholder' => 'First Name',
              'value'       => set_value('first_name','set first name')
            );

echo form_input($data);

Still no luck - it is picking up "set first name" from:
'value' => set_value('first_name','set first name')
'placeholder' => 'First Name',

Ah, sorry. Ignore the ",'set first name'" in the value field and try that.
