我试图将信息输入到数据库，同时将文件上传到服务器并将其链接存储在数据库中。此时文件上传，但是没有表单数据显示在数据库中，并返回表单无法提交的错误消息，但实际上并未指定错误。表单不提交到数据库
任何帮助将是惊人的！
<?php
$dbc=mysql_connect('localhost', 'mgertenbach', 'mollyr');
mysql_select_db('mgertenbach', $dbc);
if($_SERVER['REQUEST_METHOD']=='POST'){
//you needed to move this INSIDE the conditional.. you had it up at line 15 which... woudl cause the errors to show.
$sqlInsertString = "INSERT INTO band_information
VALUES ('{$_POST['bandname']}', '{$_FILES['bandphoto']['name']}', '{$_POST['bandbio']}', '{$_POST['bandcity']}', '{$_POST['bandstate']}', '{$_POST['bandzipcode']}', '{$_POST['bandgenre']}', '{$_POST['bandlink']}');";
if(move_uploaded_file($_FILES['bandphoto']['tmp_name'], "C:\\HTML\\mgertenbach\\BAND\\photos\\{$_FILES['bandphoto']['name']}") && @mysql_query($sqlinsertString, $dbc)){
print '<p>Thanks for submitting your band!</p>';
} else {

mysql_error($dbc) . '</p>';
