how to write it properly?

Can you tell me how to write it properly ?
if(isset($_POST['button'])) && ($_POST['form'] = !null)){
echo 'choose something';
}
else{
echo 'great choice!';
}

if(isset($_POST['button'])) && ($_POST['form'] != null)){
echo 'choose something';
}
else{
echo 'great choice!';
}


or


if(!empty(@$_POST['form'])){
echo 'choose something';
}
else{
echo 'great choice!';
}


The @ turns off error reporting for getting the function/variable after so avoids the need to use isset.

if(isset($_POST['button'])) && ($_POST['form'] != null)){
echo 'choose something';
}
else{
echo 'great choice!';
}


or


if(!empty(@$_POST['form'])){
echo 'choose something';
}
else{
echo 'great choice!';
}

first one
Parse error: syntax error, unexpected T_BOOLEAN_AND

second one
Parse error: syntax error, unexpected '@', expecting T_STRING or T_VARIABLE or '$'

Sorry i didn't test them let me fix that.

Sorry empty seems to check if it exsists and is empty all in one hit.


<?php
if(empty($_POST['form'])){
echo 'choose something';
}
else{
echo 'great choice!';
}
?>


However you might want to use


<?php

if(!isset($_POST['button']) && $_POST['form'] == ""){
echo 'choose something';
}
else{
echo 'great choice!';
}
?>


As empty returns true if $_POST["form"] is set to 0 for instance

thank you!
a hug to you :rolleyes:

If by how to write it properly you meant why doesn't my code work it's because you forgot a left paren right after the if.
