[SOLVED] date and mktime

[richiec]

Hey guys im having a bit of an issue.. Ill try to explain it best way i can with what it is i am trying to do..

 

Ok first of all in html i have a select option with a drop down menu with a bunch of names.. Under that i have 2 text boxes for date and time (the user imputs the date and time something happend)

 

Now depending on the drop down select name clicking submit will add a set number of hours to the date and time the user submited.

 

Lets say the user imputs todays date 08-22-08 and the time 12:34pm and lets say they select a name which adds 18 hours onto that time..

 

if ($_REQUEST["Submit"] != NULL){
$name = $_REQUEST["name"];
$date = $_REQUEST["date"];
$time = $_REQUEST["time"];

if ($name == "some name"){
$add = "18"; // hours to add to the date and time
$name = "some name";
}

 

Now the output i would want, would be something like.. "$name will happen again on 08-23-08 at 6:34am" (adding 18 hours to the time and date they imputed)

 

any idea how i would do that could i get an example?

 

Thanks alot,

maybe something like

 

$ts = strtotime("$date $time") + (60 * 60 * 18);

$nt = date("m-d-y g:sa ", $ts);

Using your idea and the date and time i used in my original post (date 08-22-08 and the time 12:34pm) the output i got was:

 

will happen again on: 10-09-09 6:34 am

 

So the time was right with adding 18 hours however the date was way off, any ideas?

Ah I know why.  strtotime considers the first number to be the year when using "-" as a separator so it's parsing it as "y-m-d" instead of "m-d-y" You can fix this by changing your form to use "/" instead of "-" like "m/d/y" or by reordering the string using substr or maybe using explode like

 

$date = "08-22-08";

$temp = explode("-",$date);

$newdate = $temp[2] . "-" . $temp[0] . "-" . $temp[1];

 

then strtotime($newdate) etc...

Awesome, that works perfect now thank you very much.

 

I have never used explode before either and i used that after changing it to / at first i went back to using - and the explode code you gave and it works great.. Thank you again!

awesome.  one last thing: I accidentally did seconds instead of minutes in the date format it should be

 

 

$nt = date("m-d-y g:ia ", $ts);

Thanks again bud.
