isset on normal variables?

[SirChick]

I have a problem with my if statements

 

Now the variable is definitely set because when i echo it ... it displays the correct number! But the if statement loads the wrong parts.... this is what i tried:

 

When the variable is set == to 1 then it should load //code. How ever at the moment it is loading the url for the bus stop (the first url)

 

Is this because the isset doesn't work for variables and only will work for GET and POST?

 

If the answer is that it won't work for variables.. will it work for SESSIONS?

 

And if not for sessions is there a way to do it without do the if ( $busessions== '' )? Because if i do that sort of check then i get a notice error about the variable not being initially set (which is unavoidable with this feature im working on)

 

<php
If (!(isset($Busession))){
?>
<a href="londonbusprocess.php?bus=1">Bus Stop</a><br>
<?
}ElseIF($BusSession != 1){
?>
<a href="londonbusprocess.php?bus=1">Bus Stop</a><br>
<?
}else{
//code
}
?>

isset works in all kind of variables

 

try

<?php
if (!isset($Busession)){
?>
<a href="londonbusprocess.php?bus=1">Bus Stop</a><br>
<?
}elseif($BusSession != 1){
?>
<a href="londonbusprocess.php?bus=1">Bus Stop</a><br>
<?
}else{
//code
}
?>

Seems kinda redundant of what you're doing.  The code goes to the same location if its not set or if it doesn't = 1, which to me means that it needs to = 1 to run your code?

 

So why not just check the one value?

[cooldude832]

saying

 

<?php
if($var == 1){
}
?>

is usually the same as saying

<?Php
if($var == TRUE){
}
?>

And that has to do with what?

 

saying

 

<?php
if($var == 1){
}
?>

is usually the same as saying

<?Php
if($var == TRUE){
}
?>

You sure you didn't misspelled the first variable? You have $Busession and $BusSession.
