他我不知道你是否已经找到了解决方案，但也许你可以看看这个：
第一个html表单
只需构建一个没有提交按钮但只有一个按钮按钮的普通 html 表单。请注意，我的解决方案还有一个精美的加载栏！
<form enctype="multipart/form-data" id="myform">
<input type="text" name="some_usual_form_data" />
<br>
<input type="text" name="some_other_usual_form_data" />
<br>
<input type="file" multiple name="file[]" id="image" /> <sub>note that you have to use [] behind the name or php wil only see one file</sub>
<br>
<input type="button" value="Upload files" class="upload" />
</form>
<progress value="0" max="100"></progress>
<hr>
<div id="content_here_please"></div>
现在您可以添加accept="image/*"或以这种方式仅选择您需要或想要的文件类型。
然后用 jquery/javascript 上传
看起来像你的，但更好。
$(document).ready(function () {
$('body').on('click', '.upload', function(){
// Get the form data. This serializes the entire form. pritty easy huh!
var form = new FormData($('#myform')[0]);
// Make the ajax call
$.ajax({
url: 'action.php',
type: 'POST',
xhr: function() {
var myXhr = $.ajaxSettings.xhr();
if(myXhr.upload){
myXhr.upload.addEventListener('progress',progress, false);
}
return myXhr;
},
//add beforesend handler to validate or something
//beforeSend: functionname,
success: function (res) {
$('#content_here_please').html(res);
},
//add error handler for when a error occurs if you want!
//error: errorfunction,
data: form,
// this is the important stuf you need to overide the usual post behavior
cache: false,
contentType: false,
processData: false
});
});
});
// Yes outside of the .ready space becouse this is a function not an event listner!
function progress(e){
if(e.lengthComputable){
//this makes a nice fancy progress bar
$('progress').attr({value:e.loaded,max:e.total});
}
}
相信我，我很容易做到这一点。但是，您可以在此处创建一个 javascript 函数来验证文件以及是否需要整个表单。只需将您验证函数名称放在后面，beforeSend: youvalfunctname您也可以在那里创建一个回调，例如beforeSend: function(){ //do stuf here }. 当上传时确实发生错误时，您可以使用error:.
服务器端 php.ini 终于
你可以在这里做你想做的事，但我只是举一个例子，你可以怎么做。
<?php
$succeed = 0;
$error = 0;
$thegoodstuf = '';
foreach($_FILES["file"]["error"] as $key => $value) {
if ($value == UPLOAD_ERR_OK){
$succeed++;
//took this from: "https://stackoverflow.com/questions/7563658/php-check-file-extension"
//you can loop through different file types
$file_parts = pathinfo($filename);
switch($file_parts['extension'])
{
case "jpg":
//do something with jpg
break;
case "exe":
// do sometinhg with exe
break;
case "": // Handle file extension for files ending in '.'
case NULL: // Handle no file extension
break;
}
$name = $_FILES['file']['name'][$key];
// replace file to where you want
copy($_FILES['file']['tmp_name'][$key], './upload/'.$name);
$size = filesize($_FILES['file']['tmp_name'][$key]);
// make some nice html to send back
$thegoodstuf .= "
<br>
<hr>
<br>
<h2>File $succeed - $name</h2>
<br>
give some specs:
<br>
size: $size bytes
";
}
else{
$error++;
}
}
echo 'Good lord vader '.$succeed.' files where uploaded with success!<br>';
if($error){
echo 'shameful display! '.$error.' files where not properly uploaded!<br>';
}
echo '<br>O jeah there was a field containing some usual form data: '. $_REQUEST['some_usual_form_data'];
echo '<br>O jeah there was a field containing some usual form data: '. $_REQUEST['some_other_usual_form_data'];
echo $thegoodstuf;
?>
