Question

我正在使用输入type="file" multiple="multiple"和PHP上传循环。

<input name="data[]" id="file" type="file" multiple="multiple" class="txtinput2" />

上面是我的HTML，下面是我的PHP：

if(isset($_POST['action'])=='uploadfiles'){
$count_data=count($_FILES['data']) ;   ######### count the data #####

for($x=0;$x<$count_data;$x++)

当我回复count_data时，它会给我输出 5 ，但当我选择 28 文件时，它会显示 28 个文件在输入字段中选择。 multiple="multiple"仅支持 5 上传吗？

我检查了PHP信息，它说最大文件上传 20 ，最大帖子大小 8米，最大文件大小 128米以及总大小我尝试上传的所有文件都是 1.94 megs 。

您的阵列中共有20个文件，分为5个子阵列，根据您在问题中所说的内容，您的上传限制为。

我检查了PHP信息，它说最大文件上传20

第一个数组是每个文件的旧文件名。
第二个数组是按顺序的每个文件的文件类型第三个数组是保存文件的位置及其临时名称第四个数组是如果任何文件无法上传或不上传，我认为它将是0或1为0没有错误最后一个数组是按顺序的每个文件的文件大小。

使用以下方法计算所有文件：

$count_data=count($_FILES['data']['name']) -1;

并按照以下方式阅读：

for($i=0; $i < $count_data; $i++)
{
    if ($_FILES['data']['error'][$i] == 0)
    {
        $name = $_FILES['data']['name'][$i];
        $temp = $_FILES['data']['tmp_name'][$i];
        $type = $_FILES['data']['type'][$i];
        $size = $_FILES['data']['size'][$i];
    }
}

多个文件上载字段选项不上传所有文件
