Form Validation and Arrays - coldlamper - 02-04-2016
How can I check if a post variable is an array?
If I try this:
$this->form_validation->set_rules('data[]', 'Post Data', 'is_array');
It checks all the array elements with is_array. I want to check if 'data' is an array.
Any ideas?
Thanks,
Brian

Once you call form validation for a field with square brackets, you already seem to know it's an array, don't you?
I guess your form contains multiple fields with name="data[]".
These fields are posted as an array.
In your form validation routine, you must check which of those have a value or not.
