[SOLVED] if isset with another if

[vicodin]

Wondering if this is the right way to do it.....

I want the script to check a variable is set and if another is blank.

so would it be like this?

 

if (isset($_POST['var'] && !$_POST['var2'] ==""){
DoThisFunction();
}
else
{
echo 'Variable is not set';
}

 

Would that be correct?

if ($_POST['var'] && empty($_POST['var2'])){
DoThisFunction();
}
else
{
echo 'Variable is not set';
}

 

This is what you want.

Thanks so much!

if ($_POST['var'] && !empty($_POST['var2'])){
DoThisFunction();
}
else
{
echo 'Variable is not set';
}

 

 

i would put a ! for not empty correct?

Simple do it like this:

 

if ($_POST['var'] && empty($_POST['var2'])){
echo 'Variable is not set';
}
else
{
DoThisFunction();
}

Yeh also ! this can.

 

And upto you now which var you want to filter or for not empty or empty.
