Question

您好我正在尝试将记录插入我的数据库。字段数是可变的，取决于用户表单提交。使用以下代码

完美地插入核心数据

 if (!($stmt = $mysqli->prepare("INSERT INTO test(id) VALUES (?)"))) {


    if ($insert_stmt = $mysqli->prepare("INSERT INTO submitted_orders (order_date,customer_id,customer_email,customer_name,customer_company,customer_message,country_name,city_name,site) VALUES (?, ?, ?, ?, ?, ?, ?,?, ?)")) {
echo "Prepare failed: (" . $mysqli->errno . ") " . $mysqli->error;

   //   
};
       if ( $insert_stmt->bind_param('sisssssss', $today,$_SESSION['customer_id'],$_SESSION['email'],$_SESSION['name'],$_SESSION['company_name'],$_SESSION['message'],$_SESSION['country_name'],$_SESSION['city_name'],$_SESSION['site'])) {    echo "Binding parameters failed: (" . $insert_stmt->errno . ") " . $insert_stmt->error;};
        // Execute the prepared query.
         if (!$insert_stmt->execute()) {
echo "Execute failed: (" . $insert_stmt->errno . ") " . $insert_stmt->error;
 }

所以我的问题是我有四个定义的变量

$ scounter（这包含我的额外字段的字符串整数值，echo测试给出的值为sisisi

$ qcounter（这包含要输入的字段数，echo显示的值为？，？，？，？，？，？，

$ input1（这包含所需的数据库字段列表，ech显示测试值为order_item1，order_item1_price，order_item2，order_item2_price，order_item3，order_item3_price，

$ sinput2（这包含要输入值的变量echo显示测试值为$ order_item1，$ order_item1_price，$ order_item2，$ order_item2_price，$ order_item3，$ order_item3_price，

我需要将变量内容输入到prepare和bind参数语句中，但需要进行拼写以获得正确的语法并继续获取＆＃34;致命错误：调用非对象上的成员函数bind_param（）第141行＆＃34; /hsphere/local/home/mailman2/afbincludes/order_form_handler.php;消息

我真的很感激一些帮助，使语法正确，替代方案是添加60个字段，其中大部分都有空数据

这是我尝试插入变量的代码

if (!($stmt = $mysqli->prepare("INSERT INTO test(id) VALUES (?)"))) {
//

// post data // Insert the new user into the database 
if ($insert_stmt = $mysqli->prepare("INSERT INTO submitted_orders ('".$input1.  "',order_date,customer_id,customer_email,customer_name,customer_company,customer_message,country_name,city_name,site) VALUES ('".$qcounter."'?, ?, ?, ?, ?, ?, ?,?, ?)")) {
echo "Prepare failed: (" . $mysqli->errno . ") " . $mysqli->error;
//

//  
}; 
if ( $insert_stmt->bind_param($scounter.'sisssssss',$input2, $today,$_SESSION['customer_id'],$_SESSION['email'],$_SESSION['name'],$_SESSION['company_name'],$_SESSION['message'],$_SESSION['country_name'],$_SESSION['city_name'],$_SESSION['site'])) {    echo "Binding parameters failed: (" . $insert_stmt->errno . ") " . $insert_stmt->error;};
        // Execute the prepared query.
         if (!$insert_stmt->execute()) {
echo "Execute failed: (" . $insert_stmt->errno . ") " . $insert_stmt->error;
 }

如果您回复了查询，则会看到语法错误。

if ($insert_stmt = $mysqli->prepare("INSERT INTO submitted_orders ('".$input1.  "',order_date,customer_id,customer_email,customer_name,customer_company,customer_message,country_name,city_name,site) VALUES ('".$qcounter."'?, ?, ?, ?, ?, ?, ?,?, ?)"))

应该是

if ($insert_stmt = $mysqli->prepare("INSERT INTO submitted_orders (".$input1.  " order_date,customer_id,customer_email,customer_name,customer_company,customer_message,country_name,city_name,site) VALUES (".$qcounter." ?, ?, ?, ?, ?, ?, ?,?, ?)"))

在'和,之后/之后删除单引号$input1和逗号$qcounter。由于您的列名和占位符不应该在引号中，并且它们的值都有一个尾随逗号。

另外，

if ( $insert_stmt->bind_param($scounter.'sisssssss',$input2, $today,$_SESSION['customer_id'],$_SESSION['email'],$_SESSION['name'],$_SESSION['company_name'],$_SESSION['message'],$_SESSION['country_name'],$_SESSION['city_name'],$_SESSION['site']))

应该是

if ( $insert_stmt->bind_param($scounter.'sisssssss',rtrim($input2, ','),  $today,$_SESSION['customer_id'],$_SESSION['email'],$_SESSION['name'],$_SESSION['company_name'],$_SESSION['message'],$_SESSION['country_name'],$_SESSION['city_name'],$_SESSION['site']))

删除,

中的尾随逗号$input2

mysqli使用变量准备和插入语句以插入值和变量语法错误
