警告:mysqli_error()只需要1个参数,给定[重复] 0

This question already has an answer here:

I have searched on here for this same question being asked and found many answers that did not fix my error at all and usually just created more :P Here is the full error

Warning: mysqli_error() expects exactly 1 parameter, 0 given in F:\Jacob's Project rehashegister.php on line 54.

and here is the entire PHP page that it inhabits:

 <!DOCTYPE html>
<html>

<head>

<title>Membership Confirmation</title>
    <script type='text/javascript' src='gen_validatorv31.js'></script>
</head>

<body>
<h1></h1>
<p>Thank for your membership support!</p>

    change $data = mysqli_query($link, $query)or die(mysqli_error()); <------- Line 54

    to (simply pass the $link connection to the mysqli_error() function)

    $data = mysqli_query($link, $query)or die(mysqli_error($link)); <------- Line 54
