我重新推出了一个验证类，用于检查登录/注册表单，以代替纸质上传表单。我复制了语法，并为检查论文明确地重新创建了一个新函数。我现在的问题是它不起作用，并没有明确的迹象表明原因。我正在检查PHP error.log并且它没有显示任何异常。
请使用表单和PHP代码继承我的upload.php：
<?php
require 'core/init.php';
$user = new User();
$user->protect();
$_error = false;
$_papererror = false;
if (Input::exists()) {
if (Token::check(Input::get('token'))) {
//print_r($_FILES['paper']);
$validate = new Validate();
$papervalidate = new Validate();
$validation = $validate->check($_POST, array(
'papername' => array('required' => true, 'max' => 50)
));
$papervalidation = $papervalidate->checkPaper($_FILES, array(
'paper' => array('required' => true, 'type' => Input::get('paper')['type'])
));
if($validation->passed() && $papervalidation->passed()) {
// handle upload, and then redirection
echo "Success";
} else {
$_error = true;
}
}
}
?>

这是Validate.php类，我调用它来验证表单：
<?php

*/
class Validate {
private $_passed = false;

private $_db = null;
private $_fields = array(
'username' => 'Username',
'password' => 'Password',
're_password' => 'Repeat Password',
'name' => 'Name',
'cur_pass' => 'Current Password',
'new_pass' => 'New Password',
're_pass' => 'Repeat Password',
'papername' => 'Paper name',
'paper' => 'A paper',
'format' => 'Format is required'
);
public function __construct() {
$this->_db = DB::getInstance();
}
/*
*
*/
public function check($source, $items = array()) {
foreach($items as $item => $rules) {
foreach($rules as $rule => $rule_value) {
$value = trim($source[$item]);
$item = escape($item);
if($rule === 'required' && empty($value)) {
$this->addError("{$this->refactor($item)} is required");
} else if(!empty($value)) {
switch($rule) {
case 'min':
if(strlen($value) < $rule_value) {
$this->addError("{$this->refactor($item)} must be a minimum of {$rule_value} characters.");
}
break;

$this->addError("{$this->refactor($item)} must be a maximum of {$rule_value} characters.");
}
break;

if($value != $source[$rule_value]) {
$this->addError("{$this->refactor($rule_value)} must match {$this->refactor($item)}.");
}
break;
case 'unique':
$check = $this->_db->get($rule_value, array($item, '=', $value));
if($check->count()) {
$this->addError("{$this->refactor($item)} already exists.");
}
break;
}
}
}
}
if(empty($this->_errors)) {
$this->_passed = true;
}
return $this;
}
public function checkPaper($source, $items = array()) {
foreach($items as $item => $rules) {
foreach($rules as $rule => $rule_value) {
$value = $source['paper'];
$item = escape($item);
//die($source['paper']);
if($rule === 'required' && empty($value['paper'])) {

'application/msword'
);
if(!in_array($value, $_types)) {
$this->addError("{$this->refactor($item)} must be in a .doc .docx .txt .rtf .pdf file format");
}
break;
}
}
}
}
if(empty($this->_errors)) {
$this->_passed = true;
}
return $this;
}
/*

private function addError($error) {
$this->_errors[] = $error;

/*

在我的mac上使用Console.app查看apache2 error.log在尝试上传任意一对格式时没有显示任何错误。
我已经尝试将$ _FILES路径更改为更少动态，更静态，因为这是唯一需要验证的上传表单。
答案 0 :(得分：0)
我弄清楚我哪里出错了。由于在提交表单时创建了全局$_FILES变量，因此它将显示为非空，并设置。因此，要检查我必须将错误编号与$_FILES错误4进行比较。
所以要解决这个问题，这里有正确的checkPaper()函数：
public function checkPaper($source, $items = array()) {
foreach($items as $item => $rules) {
foreach($rules as $rule => $rule_value) {
$value = $source['paper'];
$item = escape($item);
//die($source['paper']);
if($rule === 'required' && $value['error'] == 4) {
$this->addError("{$this->refactor($item)} is required");
} else if(!empty($value)) {
switch($rule) {
case 'type':
$_types = array(
'application/pdf',
'application/vnd.openxmlformats-officedocument.wordprocessingml.document',
'text/plain',
'text/rtf',
'application/msword'
);
if(!in_array($rule_value, $_types)) {
$this->addError("{$this->refactor($item)} must be in a .doc .docx .txt .rtf .pdf file format");
}
break;
}
}
}
}
if(empty($this->_errors)) {
$this->_passed = true;
}
return $this;
}
