You can validate address field in CodeIgniter by setting up form validation rules in the controller. Here is an example code on how to validate address field:

  1. Load form validation library in the constructor of your controller:
1
2
3
4
public function __construct() {
    parent::__construct();
    $this->load->library('form_validation');
}


  1. Set up validation rules for the address field in the controller method where you are processing the form submission:
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
public function process_form() {
    $this->form_validation->set_rules('address', 'Address', 'required');
    
    if ($this->form_validation->run() == FALSE) {
        // Form validation failed, show errors
        $this->load->view('your_form_view');
    } else {
        // Form validation passed, process the form data
        // Your code to process form submission
    }
}


  1. Update your view file to display validation errors for the address field:
1
2
<input type="text" name="address" value="<?php echo set_value('address'); ?>">
<?php echo form_error('address'); ?>


By following these steps, you can validate the address field in CodeIgniter and display validation errors if the address field is not filled out correctly.
