Codeigniter - Displaying individual error message for array fields

Question

Have array of customers each with individual details. Here is a very SIMPLE example.

<input type="text" name="customer_names[]" />

In codeigniter, each customer_name is required
$this->form_validation->set_rules('customer_names[]','Customer Names','required');

If any of the customer names are blank, validation_errors(); shows one message for the entire array.

How can I obtain individual error messages for that customer?

NOTE: echo form_error('customer_names[0]'); is what I am trying to achieve where customer_name 0 was left blank.

According to the docs, that shoul work: codeigniter.com/user_guide/libraries/… What are you seeing? — swatkins

Looking at the Form Validation documentation, specifically the Using Arrays as Field Names section, I think you're going to need to explicitly name your inputs by including the index in the name to get the form_error() method to work as you desire.

So in order for form_error('customer_names[0]') to work, there will actually have to be an input with the name customer_names[0].

This worked fine for me, although I must explicitly name my fields with their respective keys in order to be useful. This answer here says that CodeIgniter 3 has a feature for this.

The answer of @machineaddict is just the same to this but I did not need to specify index in the rule name.

I was having the same problem with CodeIgniter 2.1.3. I have resolved it like this:

The input is:

<input type="text" name="customer_names[0]" /> <input type="text" name="customer_names[1]" /> ...

The form validation is:

$this->form_validation->set_rules('customer_names[0]','Customer Names','required'); $this->form_validation->set_rules('customer_names[1]','Customer Names','required'); ...

The errors are displayed like this:

echo form_error('customer_names[0]'); echo form_error('customer_names[1]'); ...
