为什么我不能使用get_post方法php从发布表单中获取值

Question

I am trying to get data from a post form, but somehow the code is stopping, so that $Title doesn't gets a value, and the second alert doesn't kick in

if(isset($_POST['title'])) {
    echo "<script type='text/javascript'>alert('test');</script>";
    $Title  = get_post($conn, 'title'); 
    echo "<script type='text/javascript'>alert('$Title');</script>";
}

I expected the $Title to get the value from the form, and being alerted. The code simply stop when it comes to $Title. it doesn't even leaves a error on chrome DevTool

Answer 1

As far as I know get_post() is not a standard php function, unless if its wordpress.

Try changing from

$Title  = get_post($conn, 'title'); 

to

$Title  = $_POST['title'];

Answer 2

The problem was that i copied some code from another project, but forgot to copy this:

function get_post($conn, $var){
return $conn->real_escape_string($_POST[$var]);}
