Question

Hi I am a beginner in programming with PHP and while I was trying to do some form validation I got this error:

“Fatal error: Can’t use function return value in write context in C:\xampp\htdocs\Web\Proiecte\Cristina\formular.php on line 67”

This is my HTML for this section:

<form id ="fabrica" action="formular.php" method="post">
    <input type="checkbox" name="unu"/>
</form>

And this is my php code:

if(isset($_POST('unu'))){
                        echo "<tr>";
                        echo "<td>a mers</td>";
                        echo "</tr>";
                    }

What am I doing wrong?

Answer 1

_POST is an associative array (a superglobal)

You can access its content using the regular array syntax

$_POST['unu']

instead of

$_POST('unu')
