Help converting times

[msaz87]

Hey all,

 

I made a form that lets the user input their time using three form fields: an hour, a minute and an AM/PM. They input it in a 12-hour clock style and then when it's submitted, it should be converted to a 24-hour style and added a DB.

 

Below is the code I have for inputting the time and immediately after that is the conversion... but I've had troubles when it comes to times within 12 AM - 12:59 AM and 12 PM - 12:59 PM. Basically, entering anything between 12 PM - 12:59 PM doesn't show up and doing the same time frame for AM spits out the PM equivalent.

 

So, just to explain once more.. if they entered 12 : 30 PM it would convert to 1230 and if they entered 12 : 30 AM it would convert to 0030.

 

Any help is greatly appreciated -- thanks!

			<select name="add_am_pm">
				<option>AM</option>
				<option>PM</option>
			</select> <input type="submit" value="add">

 

$add_am_pm		= $_REQUEST['add_am_pm'];
$add_time_hr		= $_REQUEST['add_time_hr'];
$add_time_min		= $_REQUEST['add_time_min'];

if($add_time_hr < 10) $add_time_hr = "0".$add_time_hr;

switch($add_am_pm) {
case "PM":
	if($add_time_hr == "12") $add_time_hr = 0;
	$add_time = $add_time_hr.$add_time_min + 1200;
	break;	
case "AM":
	$add_time = $add_time_hr.$add_time_min;
	break;		
}

There are lots of ways of doing it, something like this should work...

 

$hours = '12';
$minutes = '40';
$period = 'AM';
echo date("H:i", strtotime($hours.':'.$minutes.$period));

Perfect... thanks so much, Cags!
