date('w')

I have a function that doesn't seem to be working. Maybe its the way I'm calling it.

I call the function like this.

checkresupplydate();

And the function does this based on what day of the week it is.

Code:

function checkresupplydate(){ 


include_once("header.php"); 


global $db, $prefix; 





$curdayofweek = date('w'); // returns 0-6 with 0 == Sunday 





if ($curdayofweek < 1 || $curdayofweek > 3){ 


Opentable(); 


echo "Reenforcements are only allowed from Monday till Wednesday<br>";


echo " These should be done in conjunction with Moves";


Closetable(); 


} 


include('footer.php'); 


}

If it is before Sunday or after Wednesday they should not continue but have this displayed:

echo "Reenforcements are only allowed from Monday till Wednesday<br>";
echo " These should be done in conjunction with Moves";

What I am getting is just a blank page. On Tuesday I echoed out $curdayofweek and am getting 2 which is correct.

Why is this not working?

On Tuesday you should get a blank page by that logic. Is 2 < 1? No. Is 2 > 3? No. So you don't do anything. What did you expect to happen on Tuesday?

So it wouldn't do anything, However contol is left in the function and not returned to the page that called the function. From page.php I call checkresupplydate() and if it is Monday, Tuesday, or Wednesday I want control returned to page.

Then you would need a return statement,
Try this on for size.
function checkresupplydate(){
include_once("header.php");
global $db, $prefix;

$curdayofweek = date('w'); // returns 0-6 with 0 == Sunday

if ($curdayofweek < 1 || $curdayofweek > 3){ //Will only return $var on sunday, thursday friday and saturday.
//Opentable(); //make this happen no matter what day in your calling page.
$var="Reenforcements are only allowed from Monday till Wednesday<br>";
$var.= " These should be done in conjunction with Moves";
//Closetable(); //make this happen no matter what day in your calling page.
}
if (!isset($var){
return false;
}else{
return $var;
}
//include('footer.php'); //make this happen no matter what day in your calling page.
}

Call it like $condition=checkresupplydate();
if ($condition!=false){
Opentable();
echo $condition;
Closetable();
}else{
//Do something on allowed days.
}
include ('footer.php');

Keeping the work of displaying out of the hands of a conditional function allows for you to not accidently include or do something twice, and its just good practice IMO.
