我试图插入/编辑数据库记录，和我下面这个例子：http://www.killersites.com/community/index.php?/topic/3064-basic-php-system-view-edit-add-delete-records-with-mysqli/与mysqli的准备语句INSERT INTO/UPDATE数据库记录PHP形式
不过，我似乎无法得到新的记录插入到数据库。这是我到目前为止：
<?php
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);
// Allow the user to both create new records and edit existing records.
// Connect to the database.
$connect = mysqli_connect('localhost', 'user', 'password', 'database_name');
// creates the new/edit record form.
// since this form is used multiple times in this file, I have made it a function that is easily reusable
function renderForm($error = '', $id = '', $start_date = '', $company = '', $stock_code = '', $card_quantity = '', $fiske_print = '', $carrier_quantity = '', $quoted = '', $quote_details = '', $quoted_date = '', $quote_accepted = '', $quote_accepted_date = '', $proof_sent = '', $proof_sent_date = '', $proof_approved = '', $proof_approved_date = '', $reminder_date = '', $printed = '', $print_date = '', $closed_loop_allocated = '', $invoiced = '', $invoiced_date = '', $posted = '', $tracking_number = '', $postal_date = '', $paid = '', $is_bulk_load = '', $bulk_funds_recieved = '', $cards_loaded = '', $notes = '', $completed = '')

我看不出为什么它不插入新的记录。任何援助将不胜感激。
（）'，然后'bind_param（“...”，$ variable）'，**然后**定义'$ variable'，并在所有运行'execute（）'之后。看起来像'bind_param（）'只是说“从这个变量读取”，但它不会在你运行execute（）之前取得它的值。 –
检查[mysqli_stmt :: execute]（http://php.net/manual/en/mysqli-stmt.execute.php）的第一个示例。作为旁注，您不希望将修改过的数据保存到数据库中（'htmlentities（）'等），而是在读取数据**时格式化数据**。 –
@AlejandroIván由于'bind_param'使用了引用，所以可以在分配前进行绑定。当你想在循环中执行查询时，这很有用。您可以在循环之前准备并绑定一次，然后分配变量并在循环中调用'execute'。 – Barmar
