In the view file, you can do a client side validation using this:

echo "<p>Salutation: ";
 $salutationOptions = array(
                  ''  => '',
                  'Dr'  => 'Dr',
                  'Mr'    => 'Mr',
                  'Ms'   => 'Ms',
                  'Mdm' => 'Mdm',
                );
    echo form_dropdown('salutation', $salutationOptions, '', 'required="required"');
    echo "</p>";

When the user tries to submit without choosing form the dropdown, it will give them an error saying they should choose from the dropdown.

If you want it on the server side, you can do something like this:

$this->form_validation->set_rules('salutation', 'Salutation', 'required')
if($this->form_validation->run()){
    /*user has selected. use the data now*/
}else{
    /*user has not sleected data, throw error back*/
}

Use required in HTML , or

do like this

 $this->form_validation->set_rules( "Salutation","Salutation","required"); 

I hope this might help you

Thank you for the reply however this require me to have all of the options Dr, Mr, Ms and Mdm, but what i need is them to choose at least one of the options either Dr, Mr, Ms or Mdm is it possible?

Thamaraiselvam Over a year ago

what is your selection tag name? if it is salutation . do like follow , $this->form_validation->set_rules( "Salutation","Salutation","required"); now this is mandatory field so user has to select any one among them

Outliers Over a year ago

Yeah it is salutation, however as we can see from my code that i have put above, i would want them to change the value to Dr, Mr, Ms or Mdm and not leave it empty at " ", is everything more clear?:)

Thamaraiselvam Over a year ago

example in view part:

 $options = array('0' => 'SELECT SHIRT', '1' => 'Small Shirt', '1' =>
'Medium Shirt', '2' => 'Large Shirt', '3' => 'Extra Large Shirt', );
echo form_open('welcome/index');
echo form_error('field name to display error');
echo form_dropdown('field name', $options);
echo form_submit('submit', 'submit');
echo form_close();

in controller part:

$this->load->helper('form_validation');
$this->form_validation->set_rules('field name', 'name have to display in the error message', 'required'); 
if ($this->form_validation->run() == false) {
$this->load->view('your page name'); }else{
$this->load->view('another page');}

Better you would go with foreach() loop. This is the way which I came across.

<?php foreach($classes as $class) { ?>
   <option value="<?php echo $class->classesID; ?>" <?php echo set_select('class', $class->classesID); ?>>
      <?php echo $class->classes; ?>
   </option>
<?php } ?>
