How do you check if a POST variable is set?

Question

when I try:

if (isset($_POST["var"])) {

echo "variable set";

} else {

echo "variable not set";

}

... it returns "variable set" always. Is there another way?

Answer 1

Im not for sure on this, but I dont think your telling it to go anywhere.

Try

IF (isset($_POST["var"])) {

IF (isset($_POST["/var")) }

= }

echo "variable set"

= {

echo "variable not set"

Because you are not skipping the code echo "variable set" it will always come up "variable set"

What are you trying to do. Please email me if you would like more help.

Thanks hope it helps,

Answer 2

if isset() does not work for you, try this one

if ( $_POST["var"] ) {

echo "variable set";

} else {

echo "variable not set";

}

hope this helps.

Answer 3

You're doing it the right way, something else must be wrong.

Are you sure 'var' really isn't set?  Have you tried

print_r($_POST);

just prior to the code above?  That way you can see for yourself whether 'var' is set or not.

Try the empty() function
