Finding date for selected day in previous week

[Fenhopi]

Hi, I have a select box that has every week day as an option. When a user picks "Monday" and submits the form I want to echo the date of monday last week. And if he picks tuesday, I want it to give the date of Tuesday last week, on so on. How would I do that?

 

Thank you in advance!

Just to be clear, if they selected Tuesday, would you want last week's Tuesday or the last Tuesday gone?

The last Tuesday gone.

what if it's Tuesday when they pick Tuesday?

Tested.

<?php
if(isset($_GET['submit'])) {
$day = $_GET['day'];
echo date('l F jS, Y',strtotime('last ' . $day));
}
?>

<form action="">
<select name="day">
<option>Monday</option>
<option>Tuesday</option>
<option>Wednesday</option>
<option>Thursday</option>
<option>Friday</option>
<option>Saturday</option>
<option>Sunday</option>
</select>
<input type="submit" name="submit" value="submit"/>
</form>

Thank you very much!

 

I get this error though:

Warning: date() [function.date]: It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'Europe/Berlin' for 'CET/1.0/no DST' instead in

That is not an error, just a warning.

 

Just add: date_default_timezone_set()

date_default_timezone_set('America/New_York');

To the top of your script.

Or, read the message since both options for resolving the cause of the warning (and the reason for it) are very clearly stated.  Use that function to set a default timezone at runtime, or use the date.timezone INI setting (in httpd.conf, php.ini, a user.ini, .htaccess or via ini_set()).
