我使用以下代码上传文件：
<?php include("./phpincludes/header.inc.php");
$status = "";
if(@$_POST['submit']){
$pic = @$_FILES['pic']['name'];
$pic_temp = @$_FILES['pic']['tmp_name'];
$pic_type = @$_FILES['pic']['type'];
$pic_size = @$_FILES['pic']['size'];
$doc1 = @$_FILES['doc1']['name'];
$doc1_temp = @$_FILES['doc1']['tmp_name'];
$doc1_type = @$_FILES['doc1']['type'];
$doc1_size = @$_FILES['doc1']['size'];
$doc2 = @$_FILES['doc2']['name'];
$doc2_temp = @$_FILES['doc2']['tmp_name'];
$doc2_type = @$_FILES['doc2']['type'];
$doc2_size = @$_FILES['doc2']['size'];
$name = stripcslashes(htmlspecialchars(urldecode($_POST['name'])));
$phone1 = stripcslashes(htmlspecialchars(urldecode($_POST['phone1'])));
$phone2 = stripcslashes(htmlspecialchars(urldecode($_POST['phone2'])));
$address = stripcslashes(htmlspecialchars(urldecode($_POST['address'])));
$sec = stripcslashes(htmlspecialchars(urldecode($_POST['sec_amount'])));
if($name != ""){
if($pic_size <= 1048576){
if (!$pic_temp) { // if file not chosen
echo "ERROR: Please browse for a file before clicking the upload button. ".$pic_temp;
}
$chars = "abcdefghijklmnopqrstuvrstwxyzABCDEFGHIJKLMNOPQRSTUVWXWZ0123456789";
$rand_dir_name = $name." ".substr(str_shuffle($chars), 0, 6);
mkdir("uploads/vendors/$rand_dir_name");
move_uploaded_file($doc1_temp, "uploads/vendors/$rand_dir_name/$doc1");
move_uploaded_file($doc2_temp, "uploads/vendors/$rand_dir_name/$doc2");
if(move_uploaded_file($pic_temp, "uploads/vendors/$rand_dir_name/$pic")){
echo "uploads/vendors/$rand_dir_name/$pic";
} else {
echo "move_uploaded_file function failed";
}
}else{
echo "Image size should be less than 1 MB!";
}
}else{
echo "Name is neccassary!";
}
}
?>
但问题是它在上传文件时给出了错误'错误：请在点击上传按钮之前浏览文件。'并且'move_uploaded_file函数失败'。我认为问题在于@在文件前面但是当我删除它时会给我一个未定义索引的错误。
我的HTML表单： -
<form method='POST' name='form'>
<td><h4>Photo:</h4><input type='file' name='pic' accept="image/gif, image/jpeg, image/png"><h4>Full Name:</h4><input class='tableinput' type='text' placeholder='Name' name='name'></td>
<td><h4>Phone 1:</h4><input class='tableinput' type='text' placeholder='Phone' name='phone1'>
<h4>Phone 2:</h4><input class='tableinput' type='text' placeholder='Phone' name='phone2'></td>
<td>
<h4>Document 1:</h4>
<input type='file' name='doc1'>
<h4>Document 2:</h4>
<input type='file' name='doc2'>
</td>
<td><h4>Service:</h4><input class='tableinput' type='text' placeholder='Service' name='services'>
<h4>Address:</h4><input class='tableinput' type='text' placeholder='Address' name='address'></td>
<td> <input class='tableinput' type='text' placeholder='Sercurity Amount' name='sec_amount'></td>
<td >
<input type='submit' id='submit' name='submit' style='display:none;'/>
<i class='glyphicon glyphicon-ok-sign tableglyp blue' aria-hidden='true' onclick='submit()'>
</i>
</td>
</form>
请帮忙！

您的错误的主要原因是：
1）表单上的html不会传递文件，因为表单标记缺少属性
2）检查事物状态的逻辑是有缺陷的。
3）您正在非常手动地进行处理
4）谨慎使用@符号（几乎从不），您要修复错误
这是一个非常基本的上传脚本。首先，我想首先组织$_FILES数组，这使我对它更具可读性。最后，将所有业务逻辑转换为函数，以便您可以从页面中获取逻辑（当您想要使用它们时，可以包含它们）：
<强> /functions/getFiles.php
function getFiles()
{
$files = array();
foreach($_FILES as $keyname => $files) {
foreach($_FILES[$keyname]['name'] as $key => $value) {
if($_FILES[$keyname]['error'][$key] != 0)
continue;
$file[$keyname][$key]['name'] = $_FILES[$keyname]['name'][$key];
$file[$keyname][$key]['type'] = $_FILES[$keyname]['type'][$key];
$file[$keyname][$key]['tmp_name'] = $_FILES[$keyname]['tmp_name'][$key];
$file[$keyname][$key]['error'] = $_FILES[$keyname]['error'][$key];
$file[$keyname][$key]['size'] = $_FILES[$keyname]['size'][$key];
}
}
return $file;
}
此函数将转换$_FILES数组：
Array
(
[pic] => Array
(
[name] => Array
(
[0] => IMG_7506.JPG.jpeg
)
[type] => Array
(
[0] => image/jpeg
)
[tmp_name] => Array
(
[0] => /datatmp/phpTNMUP2
)
[error] => Array
(
[0] => 0
)
[size] => Array
(
[0] => 1003150
)
)
[doc] => Array
(
[name] => Array
(
[0] => gI_0_DiscoveryLogovertical1.jpg
[1] => gI_0_DiscoveryLogovertical2.jpg
)
[type] => Array
(
[0] => image/jpeg
[1] => image/jpeg
)
[tmp_name] => Array
(
[0] => /datatmp/phpjY1IYG
[1] => /datatmp/phpVsX37k
)
[error] => Array
(
[0] => 0
[1] => 0
)
[size] => Array
(
[0] => 43318
[1] => 43318
)
)
)
为：
Array
(
[pic] => Array
(
[0] => Array
(
[name] => IMG_7506.JPG.jpeg
[type] => image/jpeg
[tmp_name] => /datatmp/phpTNMUP2
[error] => 0
[size] => 1003150
)
)
[doc] => Array
(
[0] => Array
(
[name] => gI_0_DiscoveryLogovertical1.jpg
[type] => image/jpeg
[tmp_name] => /datatmp/phpjY1IYG
[error] => 0
[size] => 43318
)
[1] => Array
(
[name] => gI_0_DiscoveryLogovertical2.jpg
[type] => image/jpeg
[tmp_name] => /datatmp/phpVsX37k
[error] => 0
[size] => 43318
)
)
)
现在您创建一个执行上传的功能。这是一个简单的例子：
<强> /functions/uploadFiles.php
function uploadFiles($files,$dir,&$errors,$max = 1048576)
{
if(!is_dir($dir)) {
if(!mkdir($dir,0755,true))
throw new Exception('Upload folder could not be created.');
}
foreach($files as $key => $file) {
$name = preg_replace('/[^a-zA-Z0-9\.\-\_]/','',$file['name']);
if(empty($name)) {
$error[$key][] = 'Name can not be empty.';
continue;
}
if($file['size'] > $max) {
$errors[$key][] = htmlspecialchars($file['name']).' is too large ('.number_format($max/1024,0).' KB max)';
continue;
}
if(!move_uploaded_file($file['tmp_name'],$dir.$file['name']))
$errors[$key][] = 'File could not be uploaded';
}
}
将此作为可重复使用的功能更容易：
<强> /functions/createRandName.php
function createRandName($name)
{
$chars = "abcdefghijklmnopqrstuvrstwxyzABCDEFGHIJKLMNOPQRSTUVWXWZ0123456789";
return $name." ".substr(str_shuffle($chars), 0, 6);
}
使用：
# Include the functions here
require_once(__DIR__.'/functions/createRandName.php');
# ...etc.
# Set your error array
$errors = array();
#check that a post is set
if(!empty($_POST['submit'])) {
# Create the directory
$dir = __DIR__.'/'.createRandName(preg_replace('/[^0-9a-zA-Z\s\_\-]/','',$_POST['name'])).'/';
# Because the upload hinges on a folder being created first that doesn't
# already exist, we want to stop the process as a whole if the directory
# fails to be created
try {
# Organize the files and loop through them
foreach(getFiles() as $input => $files) {
# Upload the files
uploadFiles($files,$dir,$errors);
}
}
catch (Exception $e) {
$errors[] = $e->getMessage();
}
}
# Report errors
if(!empty($errors))
print_r($errors);
?>
您的表单标记需要enctype='multipart/form-data'才能上传文件。您应该将所有文件名排列为pic[]和doc[]，即使您只有一个文件也是如此。这样你的文件都可以使用上面相同的上传机制。
<table>
<form method='POST' name='form' enctype='multipart/form-data'>
<td>
<h4>Photo:</h4>
<input type='file' name='pic[]' accept="image/gif, image/jpeg, image/png">
<h4>Full Name:</h4>
<input class='tableinput' type='text' placeholder='Name' name='name'>
</td>
<td>
<h4>Phone 1:</h4>
<input class='tableinput' type='text' placeholder='Phone' name='phone[1]'>
<h4>Phone 2:</h4>
<input class='tableinput' type='text' placeholder='Phone' name='phone[2]'></td>
<td>
<h4>Document 1:</h4>
<input type='file' name='doc[]'>
<h4>Document 2:</h4>
<input type='file' name='doc[]'>
</td>
<td>
<h4>Service:</h4>
<input class='tableinput' type='text' placeholder='Service' name='services'>
<h4>Address:</h4>
<input class='tableinput' type='text' placeholder='Address' name='address'>
</td>
<td>
<input class='tableinput' type='text' placeholder='Sercurity Amount' name='sec_amount'>
</td>
<td>
<input type='submit' id='submit' name='submit' />
<i class='glyphicon glyphicon-ok-sign tableglyp blue' aria-hidden='true' onclick='submit()'></i>
</td>
</form>
</table>
使用此表单布局，您的表单发布数组将如下所示：
Array
(
[name] => My Name
[phone] => Array
(
[1] => 123-123-1233
[2] => 321-698-7894
)
[services] => Something
[address] => 123 My Street
[sec_amount] => 123
[submit] => Submit
)
