To create a drop down that displays a set of possible values, consider the following field array:

$opts['fdd']['month'] = array(
  // set the default to the current 2-digit month (leading zero's)
  'default'    => date('m'),
  'help|ACP'   => 'Select',
  'input'      => '',
  'maxlen'     => 2,
  'name'       => 'Month',
  'options'    => 'ACPVDFL',
  'required'   => false,
  // specify D to create a drop down SELECT
  'select'     => 'D',
  'sort'       => true,
  // a simple array of values
  'values'     => array('', '01', '02', '03', '04', '05', '06', '07', '08', '09', '10', '11', '12')
);

Readability is sometimes enhanced by post-initializing the arrays of values. The following is equivalent to the above month array.

$opts['fdd']['month'] = array(
  'default'    => date('m'),
  'help|ACP'   => 'Select',
  'input'      => '',
  'maxlen'     => 2,
  'name'       => 'Month',
  'options'    => 'ACPVDFL',
  'required'   => false,
  'select'     => 'D',
  'sort'       => true
);
// Post-initialized values
$opts['fdd']['col_name']['values'] = array('', '01', '02', '03', '04', '05', '06', '07', '08', '09', '10', '11', '12');

The following are examples of post-initialized arrays used to create drop down SELECT boxes for phpMyEdit forms. Change col_name to the name of your field.

$opts['fdd']['col_name']['values'] = array('0', '1');

$opts['fdd']['col_name']['values'] = array('No', 'Yes');

$opts['fdd']['col_name']['values'] = array('Yes', 'No');

$opts['fdd']['col_name']['values'] = array('', '01', '02', '03', '04', '05', '06', '07', '08', '09', '10', '11', '12');

$opts['fdd']['col_name']['values'] = array('', '01', '02', '03', '04', '05', '06', '07', '08', '09', '10', '11', '12', '13', '14', '15', '16', '17', '18', '19', '20', '21', '22', '23', '24', '25', '26', '27', '28', '29', '30', '31');

$opts['fdd']['col_name']['values'] = range(1, 12);

$opts['fdd']['col_name']['values'] = range(1970, date('Y'));

$opts['fdd']['col_name']['values'] = array('0', '1', '2', '3', '4', '5', '6', '7', '8', '9');

$opts['fdd']['col_name']['values'] = array('A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z');

$opts['fdd']['col_name']['values'] = array( '', 'Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday' );

$opts['fdd']['col_name']['values'] = array('', 'Jr', 'Sr', 'III', 'PhD', 'MD', 'Esq', 'CEO');

$opts['fdd']['col_name']['values'] = array('', 'Mr.', 'Mrs.', 'Ms.', 'Professor', 'Doctor');

$opts['fdd']['col_name']['values'] = array( '', 'Alabama', 'Alaska', 'Arizona', 'Arkansas', 'California', 'Colorado', 'Connecticut', 'Delaware', 'Dist. of Columbia', 'Florida', 'Georgia', 'Hawaii', 'Idaho', 'Illinois', 'Indiana', 'Iowa', 'Kansas', 'Kentucky', 'Louisiana', 'Maine', 'Maryland', 'Massachusetts', 'Michigan', 'Minnesota', 'Mississippi', 'Missouri', 'Montana', 'Nebraska', 'Nevada', 'New Hampshire', 'New Jersey', 'New Mexico', 'New York', 'North Carolina', 'North Dakota', 'Ohio', 'Oklahoma', 'Oregon', 'Pennsylvania', 'Rhode Island', 'South Carolina', 'South Dakota', 'Tennessee', 'Texas', 'Utah', 'Vermont', 'Virginia', 'Washington', 'West Virginia', 'Wisconsin', 'Wyoming' );

If using the same values in multiple forms, you may find it easier to it may be easier to place commonly used arrays in an include file used by various forms.
