Question

我想上传多个文件上传。它几乎类似于简单文件上传，但我们需要用html标记进行一些修改 PHP代码。需要多个属性来添加html标记。 Firefox，Chrome，Safari和IE 9+等主要网络浏览器都支持此功能属性。我将向您展示如何使用PHP上传多个文件和基本的HTML表单，但缺少它（多个文件不是上传）

我试过下面的代码

HTML CODE

<html>
<head>

<?php

if (isset($message)) {
foreach ($message as $msg) {
printf(“<p class=’status’>%s</p></ br>\n”, $msg);
}
}
# success message
if($count !=0){
printf(“<p class=’status’>%d files added successfully!</p>\n”, $count);
}
?>
<title>Multiple File upload with PHP</title>
</head>
<body>
<form action=”” method=”post” enctype=”multipart/form-data”>
<input type=”file” id=”file” name=”files” multiple=”multiple” accept=”image/*” />
<input type=”submit” value=”Upload!” />
</form>
</body>
</html>

PHP SCRIPT

<?php
$valid_formats = array(“jpg”, “png”, “gif”, “zip”, “bmp”);
$max_file_size = 1024*5000; //100 kb
$path = “uploads/”; // Upload directory
$count = 0;

if(isset($_POST) and $_SERVER[‘REQUEST_METHOD’] == “POST”){
// Loop $_FILES to exeicute all files
foreach ($_FILES[‘files’][‘name’] as $f => $name) {
if ($_FILES[‘files’][‘error’][$f] == 4) {
continue; // Skip file if any error found
}
if ($_FILES[‘files’][‘error’][$f] == 0) {
if ($_FILES[‘files’][‘size’][$f] > $max_file_size) {
$message[] = “$name is too large!.”;
continue; // Skip large files
}
elseif( ! in_array(pathinfo($name, PATHINFO_EXTENSION), $valid_formats) ){
$message[] = “$name is not a valid format”;
continue; // Skip invalid file formats
}
else{ // No error found! Move uploaded files
if(move_uploaded_file($_FILES[“files”][“tmp_name”][$f], $path.$name))
$count++; // Number of successfully uploaded file
}
}
}
}

?>

Answer 1

将files[]用于<input>名称attaribute

 <input type=”file” id=”file” name=”files[]” multiple=”multiple” accept=”image/*” />

我们还需要为文件输入类型文件名提供像files[]这样的分组符，并且需要添加名为multiple的属性。此处accept是一个可选属性，用于允许用户仅上传图像文件。

Answer 2

替换files[]之类的输入文件名，而不是files，请参阅以下表单示例：

<form action="" method="post" enctype="multipart/form-data">
    <input type="file" id="file" name="files[]" multiple="multiple" accept="image/*" />
    <input type="submit" value="Upload!" />
</form>
