how to validate array value in codeigniter

Question

I have in my form work experience which is added dynamically with input as organisation name, department name, position and duration.

<tr>
    <td><span class="serial_no">1</span></td>
    <td><input type="text" name="organization[]" size="50"/></td>
    <td><input type="text" name="department[]" size="50"></td>
    <td><input type="text" name="positions[]" size="40"></td>
    <td><input type="text" name="duration[]"></td>
</tr>

While validating in CI I did the following:

$organization = $this->input->post('organization');
$department   = $this->input->post('department');
$positions    = $this->input->post('positions');
$duration     = $this->input->post('duration');

//printr($organization);
for($i = 0; $i < count($organization); $i++) 
{
    $org = $organization[$i];
    $dept = $department[$i];
    $pos = $positions[$i];
    $dura = $duration[$i];

    $this->form_validation->set_rules($org, "Organization", "trim|xss_clean|max_length[1]");
    $this->form_validation->set_rules($dept, "Department", "trim|xss_clean|max_length[50]");
    $this->form_validation->set_rules($pos, "Position", "trim|xss_clean|max_length[40]");
    $this->form_validation->set_rules($dura, "Duration", "trim|xss_clean|integer");
}

And displayed error as:

<?php
    echo form_error("organization[]");
    echo form_error("department[]"); 
    echo form_error("positions[]"); 
    echo form_error("duration[]");
?>

Now the problem is it doesn't validate the duration as integer. Even if I put some random alpha characters it doesn't show errors.

When I validate as follows:

$this->form_validation->set_rules('organization[]', "Organization", "trim|xss_clean|max_length[50]");
$this->form_validation->set_rules('department[]', "Department", "trim|xss_clean|max_length[50]");
$this->form_validation->set_rules('positions[]', "Position", "trim|xss_clean|max_length[40]");
$this->form_validation->set_rules('duration[]',"Duration", "trim|xss_clean|numeric");

It doesn't let me submit the form as it takes duration as mandatory which it isn't.

How do I solve it?

any help/suggestions are welcome. thanks.

Maybe you shouldn;t add trim (and xss_clean too) to duration validation? — u_mulder

It doesn't let me submit the form If so, It sounds like a bug.

Temporarily, you can check whether duration[] array is empty or not:

if (! empty($_POST['duration'])) {
    $this->form_validation->set_rules('duration[]',"Duration", "trim|xss_clean|numeric");
}

I'll update my answer if I found the main solution.

Update: This is a bug as I expected, I opened a PR at CodeIgniter Repository, that would fix this issue.

So as suggested by @ Hashem Qolami I did the following changes in my code and it worked.

$organization    = $this->input->post('organization');
$department      = $this->input->post('department');
$positions       = $this->input->post('positions');
$duration        = $this->input->post('duration');

foreach($organization as $ind=>$val) 
{
    $org  = $organization[$ind];
    $dept = $department[$ind];
    $pos  = $positions[$ind];
    $dura = $duration[$ind];

    $this->form_validation->set_rules("organization[".$ind."]", "Organization", "trim|xss_clean|max_length[1]");
    $this->form_validation->set_rules("department[".$ind."]", "Department", "trim|xss_clean|max_length[50]");
    $this->form_validation->set_rules("positions[".$ind."]", "Position", "trim|xss_clean|max_length[40]");
    if(!empty($dura))
       $this->form_validation->set_rules("duration[".$ind."]", "Duration", "trim|xss_clean|integer");
}

and displayed my errors as follows

 for($i = 0; $i < count($organization); $i++) {
     echo form_error("organization[".$i."]"); 
     echo form_error("department[".$i."]"); 
     echo form_error("positions[".$i."]"); 
     echo form_error("duration[".$i."]");
  }
