[RESOLVED] AND/OR operators

[Velausanakha]

Isn't it possible to have more than 2 && or || operators?

below I've posted some rough code and anything with 3 or more operands doesn't seem to work but all the stuff I have with 2 or less works

So Isn't it possible to have more than 2 && or || operators?

$variables=$_POST['variousFields'];

if(strlen($AddLn2) < 1 && strlen($Email) < 1 && strlen($Phone) < 1){

doSomething();

}
elseif(strlen($AddLn2) > 0 && strlen($Email) > 0 && strlen($Phone) > 0){

doThis();

}
else
{

doThat();
}

Isn't it possible to have more than 2 && or || operators?

Yes, of course it's possible. If you're having problems it's probably to do with your logic, or maybe the bracketing of terms together. e.g.

if ($condition1 == true && $condition2 == true || $condition3 == true)
{
    // mooo
}

// this is totally different from

if ($condition1 == true && ($condition2 == true || $condition3 == true))
{
   // baaaaa
}

I meant three of the same operators

Not sure if that makes a difference but see the example I provided earlier?

When I have more than 2 fields do anything (usually 3) it only works on 2 of the 3

Provide an example that can be tested. In your example, $AddLn2, $Email and $Phone come from nowhere, and $variables is useless. It is also not known what you actually intended to do, so nothing useful can be deduced from the example.

For example, I might write:

$x = 0;
$y = 0;
$z = 0;

if ($x == 0 && $y == 0 && $z == 0) {
	echo 'All are equal to zero';
} elseif ($x > 0 && $y > 0 && $z > 0) {
	echo 'All are greater than zero';
} else {
	echo 'Not all are equal to zero, and not all are greater than zero';
}

Then I would tweak the values to demonstrate the problem.

$variables=$_POST['variousFields'];

Just means

$AddLn1=$_POST['AddressLn1'];
$AddLn2=$_POST['AddressLn2'];
$Sub=$_POST['Suburb'];

and so on

other than that the initial code is accurate except for the fact it is a part of a larger elseif code

I just assign a numerical variable

$var=1;

throughout then use that as a switch to try and update a database

CASE 1: $SQL_Exec_String3 = "Update Address Set AddressLn1='$AddLn1', AddressLn2='$AddLn2', Suburb='$Sub', State='$Province', Postcode='$Zip', Country='$Nation', PrefEmail='$Email' where PersonID=".$_SESSION['ID'];
			$cur3=odbc_exec($cnx, $SQL_Exec_String3);
//if(!$cur3)  TO Break etc

The only problem I have is involved with those that take 3 options

I'm not interested in my other errors you see in the code just how to fix this particular problem

switch($var){

CASE 7: $SQL_Exec_String9="Update Address Set AddressLn1='$AddLn1', AddressLn2='$AddLn2', Suburb='$Sub', State='$Province', Postcode='$Zip', Country='$Nation', PrefPhone='$Phone', PrefEmail='$Email' where PersonID=".$_SESSION['ID'];
		echo "This is 9 ".$SQL_Exec_String9;//doesn't work
		$cur3=odbc_exec($cnx, $SQL_Exec_String9);
		break;

CASE 1: $SQL_Exec_String3 = "Update Address Set AddressLn1='$AddLn1', AddressLn2='$AddLn2', Suburb='$Sub', State='$Province', Postcode='$Zip', Country='$Nation', PrefEmail='$Email' where PersonID=".$_SESSION['ID'];
		$cur3=odbc_exec($cnx, $SQL_Exec_String3);
		echo "This is 3 ".$SQL_Exec_String3;
		break;

CASE 2: $SQL_Exec_String4 = "Update Address Set AddressLn1='$AddLn1', Suburb='$Sub', State='$Province', Postcode='$Zip', Country='$Nation', PrefPhone='$Phone', PrefEmail='$Email' where PersonID=".$_SESSION['ID'];
		$cur3=odbc_exec($cnx, $SQL_Exec_String4);
		echo "This is 4 ".$SQL_Exec_String4;
		break;

CASE 3: $SQL_Exec_String5="Update Address Set AddressLn1='$AddLn1', AddressLn2='$AddLn2', Suburb='$Sub', State='$Province', Postcode='$Zip', Country='$Nation', PrefPhone='$Phone' where PersonID=".$_SESSION['ID'];
		$cur3=odbc_exec($cnx, $SQL_Exec_String5);
		echo "This is 5 ".$SQL_Exec_String5;
		break;

CASE 4: $SQL_Exec_String6="Update Address Set AddressLn1='$AddLn1', Suburb='$Sub', State='$Province', Postcode='$Zip', Country='$Nation', PrefEmail='$Email' where PersonID=".$_SESSION['ID'];
		$cur3=odbc_exec($cnx, $SQL_Exec_String6);
		echo "This is 6 ".$SQL_Exec_String3;
		break;

CASE 5:  $SQL_Exec_String7="Update Address Set AddressLn1='$AddLn1', Suburb='$Sub', State='$Province', Postcode='$Zip', Country='$Nation', PrefPhone='$Phone' where PersonID=".$_SESSION['ID'];
		$cur3=odbc_exec($cnx, $SQL_Exec_String7);
		echo "This is 7 ".$SQL_Exec_String3;
		break;

CASE 6:  $SQL_Exec_String8="Update Address Set AddressLn1='$AddLn1', AddressLn2='$AddLn2', Suburb='$Sub', State='$Province', Postcode='$Zip', Country='$Nation' where PersonID=".$_SESSION['ID'];
		$cur3=odbc_exec($cnx, $SQL_Exec_String8);
		echo "This is 8 ".$SQL_Exec_String3;
		break;



CASE 8:  $SQL_Exec_String10= "Update Address Set AddressLn1='$AddLn1', Suburb='$Sub', State='$Province', Postcode='$Zip', Country='$Nation' where PersonID=".$_SESSION['ID'];
		echo "This is 10 ".$SQL_Exec_String10;//doesn't work
		$cur3=odbc_exec($cnx, $SQL_Exec_String10);//this should be string 10
		break;

DEFAULT: echo "You must enter data in all the required fields";//doesn't work
	PageRedirect('details.php');
	break;
}

My problem of course is with those that have to assess three options rather than two cos they're the ones that don't work but Case 7 seems to use Case 1 instead o Case 7 and Case 8 uses Case 4
