PHP Date Picker

This is a simple to use script that can be called at anytime to insert a date picker into your form.

Example

Usage

Just make a call to

echo DatePicker();

wherever you want the date picker to show. If you want to use it multiple times, just call it multiple times like

echo DatePicker();
echo DatePicker();

but make sure you have the first line of the code un commented.

The Code

$iDatePickerCounter = ";              // Used for having multiple date pickers
                                                                // comment it out if you're only going to
                                                                // use ONE datepicker call on this page.
                                                                // (It'll make the form element names
                                                                // nicer to work with).
$sYearName                = 'Year';    // Base name for the Year form element
$sMonthName         = 'Month';  // Base name for the Month form element
$sDayName                   = 'Day';      // Base name for the Day form element

$iFromYear                  = 1985;              // Starting Year
$iToYear                        = 2030;  // Ending Year

function DatePicker(){
        // Call up the global variables
        global $iDatePickerCounter,
                   $sYearName,
                   $sMonthName,
                   $sDayName,
                   $iFromYear,
                   $iToYear;
       
        // Set up some base variables
        $sPostFix = ";
        $sNL = "\r\n";
       
        // If we're using the counter (for more than one
        // date picker), increment the counter and create
        // the postfix string.
        if(isset($iDatePickerCounter)){
                $iDatePickerCounter++;
                $sPostFix = '_' . $iDatePickerCounter;
        }
       
        // Start the coding of the SELECT areas
        $sYearDropDown  = '<select name="' . $sYearName . $sPostFix . '" id="' . $sYearName . $sPostFix . '">' . $sNL;

                // Here we're checking if a POST or GET variable with
                // the same name as this SELECT element is set. If it
                // is, then we're going to see if the values of the
                // SELECT element (in this iteration) matches the
                // value of the request element. If it does, well set
                // this option as selected by default.
