PDO查询在本地工作，不在服务器上工作 [英] PDO queries works locally, not on server

问题描述

我正在执行对MySQL数据库的插入查询，并且查询在XAMPP本地上可以很好地工作，但是当我在服务器上尝试完全相同的代码时却不能.

I'm executing an insert query to a MySQL database and the queries work perfectly fine on XAMPP locally, but not when I try the exact same code on the server.

这是代码:

if($app['database']->insert('tickets', [
    'error' => $error,
    'productid' => $productid,
    'counterblack' => $counterblack,
    'countercolor' => $countercolor,
    'time' => $time,
    'date' => $date,
    'active' => 1
]))
{
    header("Location: ../Tasks.php");
}
else
{
    echo "Error";
}

插入功能:

public function insert($table, $parameters)
{
    $query = sprintf('insert into %s (%s) VALUES (%s)', $table, implode(', ', array_keys($parameters)), ':' . implode(', :', array_keys($parameters)));
    $statement = $this->pdo->prepare($query);
    $statement->execute($parameters);
    return $this->pdo->lastInsertId();
}

由于某种原因，它总是转到else部分，并在执行代码时显示错误".

For some reason, it always goes to the else part and displays 'Error' when code is executed.

我在$this->pdo->errorInfo();上使用了var_dump，输出为:

I used var_dump on $this->pdo->errorInfo(); and the output is:

array(3){[0] =>字符串(5)"00000" [1] => NULL [2] => NULL}

array(3) { [0]=> string(5) "00000" [1]=> NULL [2]=> NULL }

数据库模式类似于我从XAMPP导出并将其直接上传到服务器.这可能是什么问题?谢谢！

The database schema is similar as I exported from XAMPP and uploaded it straight to the server. What could be the issue here? Thanks!

我忘了添加一些重要信息，相同的插入查询可在不同的表上使用，但不适用于此票证"表.

I forgot to add some important information, the same insert query works on the different table, but it's not working on this 'tickets' table.

不是重复的，因为我尝试将关键字更改为不同的列名，但问题仍然存在.

Not a duplicate since I tried changing the keywords to different column names, still issue persists.

推荐答案

如果确实如此令人困惑，那为什么不尝试阅读错误消息呢?

If it really so confusing then why not to try to read an error message?

<?php
    ...
    $statement = $this->pdo->prepare($query);
    /* insert this */
    if (!$statement) {
        echo "\PDO::errorInfo():\n";
        print_r($this->pdo->errorInfo());
    }
    ...
    ?>
