I am trying to use Form Validation with an Array for field names. I was hoping that it was possible to validate each field individually, I've followed the documentation closely but I when I submit the form the validation message should display for one field but it displays for all fields. What have I done wrong?

View:

Code:
<!DOCTYPE html>

<html lang="en">

<head>

    <meta charset="UTF-8">

    <title>Document</title>

</head>

<body>

    <form method="post">

        <input type="text" name="options[]" value="<?php echo set_value('options[]'); ?>">

        <?php echo form_error('options[]'); ?>

        <br>

        <input type="text" name="options[]" value="<?php echo set_value('options[]'); ?>">

        <?php echo form_error('options[]'); ?>

        <br>

        <input type="text" name="options[]" value="<?php echo set_value('options[]'); ?>">

        <?php echo form_error('options[]'); ?>

        <br>

        <input type="submit">

    </form>

</body>

</html>

Controller Method:

PHP Code:
public function array_validation()
{
    $this->load->helper( 'form' );
    $this->load->library('form_validation');
    $this->form_validation->set_rules('options[]', 'Options', 'trim|numeric');
    if ($this->form_validation->run() == FALSE) {
        // form empty or validation failed
    } else {
    }
    $this->load->view('welcome/array_validation');
}

@rich8374,

You could potentially have a name for each one such as name_01, name_02, name_03 instead of one name of options[] ...Or...
You could keep it the way it currently is and do so extra validation after it is determined that it meets the basic field name requirements
