If statements

[ollmorris]

Is there anyway I can shrink the following if statement?

if($name == '' | $name2 == '' | $name3 == '' | $name4 == '')

Thanks

if (!(($name)|($name2)|($name3)|($name4)))

If you can call it shorter..

[ollmorris]

thanks yeah that is shorter!

I am beginning to think I have my own personal online stalker/helper :-)

!$name is not the same as $name==""

!$name means $name is not declared, and $name=="" means $name is declared, but is empty.

$test="";
if(!isset($test))
echo "is not declared";
else
"is declared, and is $test";

shows:

is declared, and is

!$name means $name is not declared, and $name=="" means $name is declared, but is empty.

!$test would also return false if $test is declared, but it's value is set to 0.

[terrabull]

!$test would also return false if $test is declared, but it's value is set to 0.

Same with:

$test=0;
if ($test=='') {
echo "empty..";
}

empty..

I guess I'm a lazy coder, but I still prefer:

if (!(($name)|($name2)|($name3)|($name4))) 

With php you can get away with it (no decleration of vars.) and it works for me.

But I also agree that there are times you'll have to do it the long way...

bye!

Thanks everyone but that does not answer how I condense this down:

if($name == '' | $name2 == '' | $name3 == '' | $name4 == '')

thanks anyway

You might want to consider putting your $name vars into an array.

$myarray = array( $name1, $name2, $name3 $name4);
//this line is putting all of your $names into an array

for ($i = 0 ; $i < sizeof($myarray) ; $i++)
{
  if (empty($my_array[$i])){
//checking each item in the array to see if its empty
  $test == 0;
  } 
}

if ($test == 0) {
echo "Opps, one of your array items are empty!";
}else{
 echo "None of your array items are empty!";
 }

Now for some reading material:
These will help you understand some of the elements in the above code:
Arrays
sizeof ()
empty()\
This may not be the best way to accomplish what you are trying to do, but at least it will help get you pointed in the right direction 🙂
