Working with Multi-Select & Dropdowns and SQL

We are talking at cross purposes here I believe.

You want to have a multi-select dropdown where a user can select more than one entry. You now want to access these entries that the user selected to use them in some way (for instance in a database query).

1. Create a select like this: <select name="lineup[]" multiple="multiple"></select>
2. Add options: <option value="x">y</option>
2. Access the ARRAY of submitted data from this select: $array = $this->input->post('lineup');
4. Use print_r($array) to see how the array is composed.
