Create a date and time combo
This function will enable you to create a set of combos that show the day, month, year, and minutes. You can configure what items to show and if you pass it a UNIX timestamp you will be able to select a default time.
You can use as many combos as you want in a single page as long as you give them a unique prefix.
<?php
define ('COMBO_YEAR', bindec('1'), true);
define ('COMBO_MONTH', bindec('10'), true);
define ('COMBO_DAY', bindec('100'), true);

define ('COMBO_MINUTE', bindec('10000'), true);
function CreateDateTimeCombo ($timestamp = '', $prefix = '', $options = '') {
// Create a full combo set to enter year, month, day, hours, and minutes
// If $timestamp is not set, then actual time is assumed
// $options can be COMBO_YEAR | COMBO_MONTH | COMBO_DAY | COMBO_MINUTE | COMBO_HOUR
if ($timestamp == '') {
$timestamp = time();
}
if ($options == '') {
$options = COMBO_YEAR | COMBO_MONTH | COMBO_DAY | COMBO_HOUR | COMBO_MINUTE;
}
$showYear = (decbin($options & COMBO_YEAR) == decbin(COMBO_YEAR));

$showDay = (decbin($options & COMBO_DAY) == decbin(COMBO_DAY));
$showHour = (decbin($options & COMBO_HOUR) == decbin(COMBO_HOUR));

Usage
CreateDateTimeCombo();
Now, you obviously want to parse the result of the combo back to a UNIX timestamp to be able to use it in the rest of your application. Once you submitted the form that holds the combo you need to use the following function:
<?php
function ConsolidateDatesFromCombo ($prefix) {
// Consolidate the dates from the DateTime Combos
$optionsArray = array('year', 'month', 'day', 'hour', 'minute');
foreach ($optionsArray as $option) {
if (isset($_REQUEST[$prefix . $option])) {
$$option = doubleval($_REQUEST[$prefix . $option]);
} else {
$$option = 0;
}
}
return mktime($hour, $minute, 0, $month, $day, $year);
}
?>
Use the same prefix in both functions to identify the same combo. For example, if you called CreateDateTimeCombo() with a prefix like 'myDate', then you need to call ConsolidateDatesFromCombo() with the same prefix.
Here's a full working example with multiple combos:
<?php
define ('COMBO_YEAR', bindec('1'), true);
define ('COMBO_MONTH', bindec('10'), true);
define ('COMBO_DAY', bindec('100'), true);
define ('COMBO_HOUR', bindec('1000'), true);
define ('COMBO_MINUTE', bindec('10000'), true);
function CreateDateTimeCombo ($timestamp = '', $prefix = '', $options = '') {
// Create a full combo set to enter year, month, day, hours, and minutes
// If $timestamp is not set, then actual time is assumed
// $options can be COMBO_YEAR | COMBO_MONTH | COMBO_DAY | COMBO_MINUTE | COMBO_HOUR
if ($timestamp == '') {
$timestamp = time();
}
if ($options == '') {
$options = COMBO_YEAR | COMBO_MONTH | COMBO_DAY | COMBO_HOUR | COMBO_MINUTE;
}
$showYear = (decbin($options & COMBO_YEAR) == decbin(COMBO_YEAR));
$showMonth = (decbin($options & COMBO_MONTH) == decbin(COMBO_MONTH));
$showDay = (decbin($options & COMBO_DAY) == decbin(COMBO_DAY));
$showHour = (decbin($options & COMBO_HOUR) == decbin(COMBO_HOUR));
$showMinute = (decbin($options & COMBO_MINUTE) == decbin(COMBO_MINUTE));
if ($showDay) {
/* Day ========== */
echo '<select name="' . $prefix . 'day">' . "\n";
for ($i = 1; $i < = 31; $i++) {
echo "\t<option ";
if (date('d', $timestamp) == $i)
echo "selected ";
echo "value='".$i."'>".$i."\n";
}
echo '' . "\n";
}
if ($showMonth) {

echo "\t<option ";
if (date('m', $timestamp) == $i)
echo "selected ";
$monthName = date('F', mktime(0, 0, 0, $i, 1, 2000));
echo "value='".$i."'>{$monthName}\n";
}
echo '</select>' . "\n";
}

if (date('G', $timestamp) == $i)

printf('value="%02d">%02d', $i, $i);
}
echo '</select>' . "\n";
}
if ($showMinute) {
/* Minute ========== */
echo "\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n";

}
