[Resolved] Checking more than one condition

[g7ibby]

How would I check to see if two conditions are true in a "if" statement?

if ($a) and (!$b) {do this}

Thanks

if($a && ($b)) {
do this
}

Didnt work out.

I want to check if $a exist and $b does not exist.

The code is to varify if the enter button was pushed or if submit was pushed.

My actual code.

if ($submit) 
{
//display confirmation before posting into database
}

elseif ($bchecker && (!$submit)) 
{
//notify enter was pushed tell to go back
}

else
{
display initial form
}

Is this correct or have I missed something?

What does pressing the enter button do? Do you have a default button that this would interact with? Also, are you getting any sort of error?

try the [man]isset/man function

also look at the [man]empty/man function

if ( isset($a) && !isset($b) ) {
