Form Dropdown Validation

[eluser]Juan Velandia[/eluser]
Hello Everyone. Wich aproach would you use to validate this dropdown

$report = array();
$report[0]= 'Please Select';
$report[1]= 'Sales';
$report[2]= 'Products';
$report[3]= 'customers';

echo form_dropdown('Report', $report, '');

To make users to select something else than "Please select". Thanks in advance!


1) Create an array of valid options (excluding "Please Select").
2) When you generate the dropdown, add the "Please Select" option there (use array_merge() or something).
3) Use your original valid options array to compare the value.
