[SOLVED] If question

[bhavin_85]

Hi guys

 

i want to know if you can put and if statement within an if statement....the reason i ask is because i have created my login screen, which works, but i now need to add in an if statement so that if the access_level is set to 1 they are direted to one page, to 2 then another and to 3 another...i have had a go at it but i got an error

 

$sql="SELECT * FROM customer WHERE uname='$n' AND pwd=MD5('$p')"; 
$query=mysql_query($sql) or die("Queryfailed:".mysql_error());
if (mysql_num_rows($query) != 0) { 
$row = mysql_fetch_assoc($query);
$_SESSION['first_name'] = $row['first_name'];
$_SESSION['surname'] = $row['surname'];
$_SESSION['address1'] = $row['address1'];
$_SESSION['address2'] = $row['address2'];
$_SESSION['town'] = $row['town'];
$_SESSION['county'] = $row['county'];
$_SESSION['postcode'] = $row['postcode'];
$_SESSION['date_of_birth'] = $row['date_of_birth'];
$_SESSION['home_number'] = $row['home_number'];
$_SESSION['mobile_number'] = $row['mobile_number'];
$_SESSION['points'] = $row['points'];
$_SESSION['access_level'] = $row['access_level'];
$mytime=time();
$mytime=date("H:i:s A",$mytime);
$_SESSION['time'] = $mytime;
$_SESSION['status'] = 'logged';
$_SESSION['username'] = $n;

//header ("location:welcome.php");
if {
$_SESSION['access_level'] = '1';
header ("location:welcome1.php");
}
else if {
$_SESSION['access_level'] = '2';
header ("location:welcome2.php");
}
else if {
$_SESSION['access_level'] = '3';
header ("location:welcome3.php");
}
exit;
} else {
$_SESSION['status'] = 'not logged';
header("Location:Messages.php?msg=2" ); 
exit();
}
}

 

im gettin an - Parse error: parse error, unexpected '{', expecting '(' in C:\Program Files\xampp\htdocs\PBL\default.php on line 48

line 48 is the first if under the commented out header

 

any help is much appreciated

Yes, you can nest if statements, but you didn't put a condition on those nested "if" statements, that's why you got the error.

might be better for you to use the switch statement also...

 

Just a tip.

i got it working using the following code

 

$sql="SELECT * FROM customer WHERE uname='$n' AND pwd=MD5('$p')"; 
$query=mysql_query($sql) or die("Queryfailed:".mysql_error());
if (mysql_num_rows($query) != 0) { 
$row = mysql_fetch_assoc($query);
$_SESSION['first_name'] = $row['first_name'];
$_SESSION['surname'] = $row['surname'];
$_SESSION['address1'] = $row['address1'];
$_SESSION['address2'] = $row['address2'];
$_SESSION['town'] = $row['town'];
$_SESSION['county'] = $row['county'];
$_SESSION['postcode'] = $row['postcode'];
$_SESSION['date_of_birth'] = $row['date_of_birth'];
$_SESSION['home_number'] = $row['home_number'];
$_SESSION['mobile_number'] = $row['mobile_number'];
$_SESSION['points'] = $row['points'];
$_SESSION['access_level'] = $row['access_level'];
$mytime=time();
$mytime=date("H:i:s A",$mytime);
$_SESSION['time'] = $mytime;
$_SESSION['status'] = 'logged';
$_SESSION['username'] = $n;

if ($_SESSION['access_level'] == '1') {
header ("Location: http://localhost/PBL/welcome1.php");
}
elseif ($_SESSION['access_level'] == '2') {
header ("Location: http://localhost/PBL/welcome2.php");
}
elseif ($_SESSION['access_level'] == '3') {
header ("Location: http://localhost/PBL/welcome3.php");
exit;
}

} else {
$_SESSION['status'] = 'not logged';
header("Location:Messages.php?msg=2" ); 
exit();
}
}
