Get the value from dropdown array using codeigniter

Question

I'm new in codeigniter framework, I just want to get the values from selected dropdown array in my form using CI. Assumed these are the whole process.

I have form with auto populated cities,

example in view

<select name="city[]">
<option value="ABC"> ABC </option>
</select>

<select name="city[]">
<option value="EFG"> EFG </option>
</select>

Here is the controller

$this->form_validation->set_rules('city[]', 'city');

When I echo it out on my model form

echo $this->input->post('city');

it just shows array, Any ideas?

Because it is an array and contains multiple values. And because you can't echo an array. Use print_r() or var_dump() to see what's inside and access a specific value if you'd like or loop through the array if you want all of them. — Amal

This is because is an array :D.

When you echo a variable of type array it shows "Array", do a print_r instead

Your view should look like -

<select name="city[]" multiple="multiple">
  <option value="ABC"> ABC </option>
  <option value="EFG"> EFG </option>
</select>

PHP:

echo '<pre>'; print_r($this->input->post('city'));
