php - 数组无法正确插入表中

Question

我从一个帖子表单中成功地获得了这两个数组，并且我能够 print_r 这两个数组，现在是时候插入它了。这就是我想要的顺序，但它不会更新我的数据库，它会上传文件，并且不会返回任何错误。

我的 PDO 有什么问题？

函数 add_a_car();

print_r($vehicleinfo) 的结果 print_r($paths)

我不能让 pdo 给我错误尝试这个

$dsn = 'mysql:dbname=cardealerwins;host=127.0.0.1';
    $user = 'root';
    $password = '';
    $dbh = new PDO($dsn, $user, $password);

    $sth = $dbh->prepare($sql);
    $sth->execute($final);
    $dbh->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );

connection.php 和 pdo 的新更新

<?php
$connect_error = 'sorry we\'re expierencing connection problems.';
mysql_connect('localhost', 'root', '') or die($connect_error);
mysql_select_db('cardealerwins') or die($connect_error);


$dsn = 'mysql:dbname=cardealerwins;host=127.0.0.1';
$user = 'root';
$password = '';

try {
    $dbh = new PDO($dsn, $user, $password);
} catch (PDOException $e) {
    echo 'Connection failed: ' . $e->getMessage();
}



?>


    $dbh->pdo->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING );
    $sth = $dbh->prepare($sql);
    $sth->execute($final);
    $dbh->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
    print_r($sth->errorInfo());

KEY由于您正在对以表结构命名的每个字段进行硬编码，因此您可以这样做：

function add_a_car($picturepaths, $vehicleinfo)
{
    // we do this so we can inherit the connection 
    // from the connect.php
    global $dbh;

    // count the total needed of placeholders for the query
    $total = count($vehicleinfo) + count($images);

    // create all the placeholders
    $input_list = substr(str_repeat(',?', $total), 1);

    // create the fields list in the same order of your array
    $fields = implode(", ", array_keys($vehicleinfo));

    // since for the pictures you don't have a key we need 
    // to create the field names for it based on the amount of pictures
    for ($i = 1; $i <= count($images); $i++)
    {
        $fields .= ',picture' . $i;
    }

    // now we merge the 2 arrays into 1    
    $final = array_merge($vehicleinfo,$images);

    // here is your new SQL query
    $sql = "INSERT INTO auto ($fields) VALUES ($input_list)";

    $sth = $dbh->prepare($sql);
    $sth->execute($final);
    print_r($sth->errorInfo());
}

我不完全确定 PDO 是否只采用数组值，或者它必须是一个只有值的数组，但如果后者你可以将其更改$final为：

$final = array_merge(array_values($vehicleinfo),array_values($images));

这就是你的 connect.php 的样子：

<?php
$connect_error = 'sorry we\'re expierencing connection problems.';
$dsn = 'mysql:dbname=cardealerwins;host=127.0.0.1';
$user = 'root';
$password = '';

try
{
    $dbh = new PDO($dsn, $user, $password);
    $dbh->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
}
catch (PDOException $e)
{
    echo 'Connection failed: ' . $e->getMessage();
}
