嗯我解决我自己.....我给输入字段不同的名称,如下面的问题,这很简单。这不应该花我几天!
<input name="file" type="file" size="20" multiple="true" />
<input name="file2" type="file" size="20" multiple="true" />
<span><?php
if (isset($_POST['submit'])) {
ini_set("display_errors", 0);
$file = uploadFile('file', true, false);
$file = uploadFile('file2', true, false);//added this line.
if (is_array($file['error'])) {
$message = '';
foreach ($file['error'] as $msg) {
$message = $msg;
}
}
echo $message;
}
?>
终于成功消息部分
<?php
if (isset($_POST['submit'])) {
$file = uploadFile('file', true, false);
$file = uploadFile('file2', true, false);
if (!is_array($file['error'])) {
$message = '';
$sub=1;
$message = "<span class='isa_success'>File uploaded successfully</span>";
echo $message;
}
}
?>

某些别有用心的人可能会读这一点,所以我就对输入的名字为name="file[]"
解释。
这意味着您正在创建一个包含所选文件名的数组。对于以后把它们上传或保存的信息,你必须循环数据库槽数组:
foreach(file[] as $key){}
另一种解决方案,在我看来凌乱的代码,是给每个文件输入一个不同的名称,喜欢的人谁问题解决了他的问题。
如果我错了,请纠正我。

我创建了一个解决方案,使用php中的单个文本框上传多个图像。
<form method="post" action="" enctype="multipart/form-data" id="frmImgUpload">
<input name="fileImage[]" type="file" multiple="true" />
<input name="btnSubmit" type="submit" value="Upload" />
</form>
<?php
$i=1;
if ($_POST)
{
foreach($_FILES['fileImage']['name'] as $key => $i)
{
$file_name = $_FILES['fileImage']['name'][$key];
$file_size =$_FILES['fileImage']['size'][$key];
$file_tmp =$_FILES['fileImage']['tmp_name'][$key];
$file_type=$_FILES['fileImage']['type'][$key];
move_uploaded_file($file_tmp,"uploaded_img/".$file_name);
$i++;
}
}
?>
你卡在哪里?什么错误? – CodeZombie 2013-02-18 00:30:06
首先,你需要分享你的尝试。没有人会为你做这项工作,但我们可以纠正你的错误。如果你坚持了几天,你应该有一些进步,对吧? – 2013-02-18 00:31:59
我试图把5个文件字段放在窗体中,并给他们一个名字,如name =“file []”,但没有运气..我尝试了不同的事情,并意识到它不会工作,无论我尝试 – alte 2013-02-18 00:34:05
