我收到此錯誤.我想注冊到頁面.mysqli_stmt_bind_param():變量數與綁定參數中準備好的語句中的參數數不匹配.`

I am getting this error.i wanna register to page. mysqli_stmt_bind_param(): Number of variables doesn't match number of parameters in prepared statement in bind param. `

<?php       if(isset($_POST['submit'])) { // Was the form submitted?
        $link = mysqli_connect("localhost", "root", "", "databaseInitialization") or die ("Connection Error " . mysqli_error($link));

推薦答案

在你的插入中，有 8 列，只有 7 個綁定

In your insert, are 8 columns and only 7 binds

                     1           2        3      4        5      6
INSERT INTO user(first_name, last_name, email, password, bio, location, 
   7       8
industry,salt)
VALUES(?,?,?,?,?,?,?,?)
       1 2 3 4 5 6 7 8

綁定，缺少一個，可能是salt

The binds, is missing one, propably the salt

                               1234567 
mysqli_stmt_bind_param($stmt, 'sssssss',
   1      2        3         4       5      6          7
$fname, $lname, $password, $email, $bio, $location, $industry) or die("bind param");

s，列和變量的數量必須相同，在這種情況下為 8.要修復只需添加一個 s 和 $salt 在 bind_param()，像這樣:

the numbers of s, columns and variables must be the same, in this case 8. To fix just add one s and $salt at bind_param(), like this:

mysqli_stmt_bind_param($stmt, 'ssssssss', $fname, $lname, $password, $email, $bio, $location, $industry, $salt) or die("bind param");
