我从一个帖子表单成功获得了这两个数组，我能够print_r这两个，现在是时候插入它了。这是我想要的顺序，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出了什么问题？

我不能让pdo在尝试这个时给我错误
$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());
答案 0 :(得分：0)
由于您正在为表格结构命名的每个字段对KEY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($sth->errorInfo());
}
我不完全确定PDO是否只采用数组值，或者它必须是仅包含值的数组，但如果稍后您可以将$final更改为：
$final = array_merge(array_values($vehicleinfo),array_values($images));
这就是你的connect.php应该是这样的：
<?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();
}
