MySqli命令不同步；您现在不能运行此命令 [英] MySqli Commands out of sync; you can't run this command now

问题描述

我已将注册脚本从mysql转换为mysqli.我作为mysql正常工作，但是现在却给我错误

I have converted my register script from mysql to mysqli. I worked fine as mysql however it now gives me the error

Commands out of sync; you can't run this command now

这是我用来注册用户的功能

This is the function I use to register the user

function register_user($register_data) { 
global $myConnection;
array_walk($register_data, 'array_sanitize'); 
//Make the array readable and seperate the fields from data 
$fields = '`' . implode('`, `', array_keys($register_data)) . '`'; 
$data = '\'' . implode('\', \'', $register_data) . '\''; 
//Insert the data and email an activation email to the user 
mysqli_query($myConnection, "INSERT INTO `members` ($fields) VALUES ($data)") or die(mysqli_error($myConnection)); 
email($register_data['mem_email'], 'Activate your account', "Hello " . $register_data['mem_first_name'] . ",\n\nThank you for creating an account with H Fencing. Please use the link below to activate your account so we can confirm you identity:\n\nhttp://blah.blah.co.uk/activate.php?mem_email=" . $register_data['mem_email'] . "&email_code=" . $register_data['email_code'] . "\n\n - David & Jay "); 
}

电子邮件可以正常发送我的阵列中的正确数据.但是，没有数据插入到数据库中，我得到了上面提到的错误.我以前从未遇到过这个错误.

The email sends fine with the correct data from my array. However no data is inserted into the database and I get the error mentioned above. I have never come across this error before.

推荐答案

如果您收到 命令不同步；您现在无法在客户端代码中运行此命令 ，您以错误的顺序调用了客户端函数.

If you get Commands out of sync; you can't run this command now in your client code, you are calling client functions in the wrong order.

例如，如果您使用的是mysql_use_result()并尝试执行新的查询，然后再调用mysql_free_result()，则会发生这种情况.如果您尝试执行两个返回数据的查询而不在两者之间调用mysql_use_result()或mysql_store_result()，也会发生这种情况.

This can happen, for example, if you are using mysql_use_result() and try to execute a new query before you have called mysql_free_result(). It can also happen if you try to execute two queries that return data without calling mysql_use_result() or mysql_store_result() in between.

更新

如果为查询设置变量并将其直接粘贴到MySQL Workbench之类的文件中，则可以在执行之前检查语法.

If you make the a variable for the query and paste the variable directly into something like MySQL Workbench you can check the syntax prior to execution.

<?php
            function myConnection(){
              $myConnection = mysqli_connect('localhost', 'my_user', 'my_password', 'my_db');
              return $myConnection;
            }   


    function register_user($register_data) { 
        array_walk($register_data, 'array_sanitize'); 
        //Make the array readable and seperate the fields from data 
        $fields = '`' . implode('`, `', array_keys($register_data)) . '`'; 
        $data = "'" . implode("', '", $register_data) . "'"; 
        //Insert the data and email an activation email to the user 
        $query = "INSERT INTO `members` ($fields) VALUES ($data)";
                    $myNewConnection = myConnection();          

                    if($result = mysqli_query($myNewConnection, $query)){ 
        email($register_data['mem_email'], 'Activate your account', "Hello " . $register_data['mem_first_name'] . ",\n\nThank you for creating an account with H Fencing.

        mysqli_free_result($result);
         return ("Success");
        } else {
            echo $query;
