I’m trying to have an array display information inputted from a PHP-created HTML form.

I’m trying to have an array display information inputted from a PHP-created HTML form. I’m trying to get the entire code on to one PHP file. So far, I have:

<body>
            <form action="hello.php" method="post">
                <input type="text" name="input" placeholder="Number" />
                <input type="submit" value="submit" onclick="go()" />
            </form>
        </body>

The above code is generated using “echo” in PHP (not shown).

Then for the rest of the PHP, I have:

function go() {

            $variable = "input";

That is just the beginning of my code. The rest is unimportant. I know the $variable = “input”; part is wrong, but how do I get numbers to transfer over from inputted HTML to PHP? Thanks a lot!

    Since you’re using a POST request you’re going to want to refer to the $_POST superglobal. This variable is an array filled with any information sent by a POST request.

    Since you want to get the value from “input” you would call the the $_POST variable using the key of “input”

    function go() {
    $variable = $_POST['input'];
    // whatever else you want to do in your function
}

    Since $_POST is a superglobal it is global in every scope.

    You don’t need to include the onclick event for your submit button, unless you wanted to call a JavaScript event with it. But the mapping of the JavaScript function go() and the PHP function go() have ZERO correlation between the two.
