使用新数组的Php ajax多文件上传

其矿井上传html代码

 <div class="col-xs-12">
    <label for="upload" class="btn btn-sm btn-outline green btn-block">
       <i  class="fa fa-upload"></i>
       upload
   </label><input type="file" multiple id="upload"  class="hidden"/>
 </div>

单击上载按钮时的Ajax代码

var myFormData = new FormData();
        uploadingFile.forEach(function (file) {
            myFormData.append('myFiles', file);
        });
        myFormData.append('a', 1);
        $.ajax({
            url: 'ajax/upload.php',
            type: 'POST',
            processData: false, // important
            contentType: false, // important
            data: myFormData,success: function(data, textStatus, jqXHR)
            {
              console.log(data);
            }
        });

最后一段代码是php代码

    $myFiles=$_FILES["myFiles"];

for($i=0; $i<count($myFiles); $i++){
    $target_path = "uploaded_files/";
    print_r($myFiles[$i]);
    echo $myFiles[$i]["tmp_name"]."\n";
    $ext = explode('.',$myFiles[$i]["tmp_name"]);
    $target_path = $target_path . md5(uniqid()) . "." . $ext[count($ext)-1];

    $sonuc=move_uploaded_file($myFiles[$i], $target_path);
    if(move_uploaded_file($myFiles[$i], $target_path)) {
        echo "The file has been uploaded successfully \n";
    } else{
        echo "There was an error uploading the file, please try again! \n";
    }
}

$myFiles=$\u文件[“myFiles”]；
对于（$i=0；$i，当您获得空对象时，我认为您没有提交文件。我认为您没有在表单标记中使用enctype=“multipart/form data”。我认为如果您像下面这样将其添加到表单中，它会起作用


您使用这行代码
myFormData.append（'myFiles'，file）；
附加单个文件。您必须使用这段代码
myFormData.append（'myFiles[]，file）；
发送多个文件。下面是我实现的可以上载多个文件的代码

在脚本中，将其放置在代码下面

<script type="text/javascript">
    $("#upload").change(function (event) {
        var files = event.target.files;
        var uploadingFile = [];
        files = Object.values(files);
        files.forEach(function (file) {
            if (file.type.match('image')
                || file.type.match('application/vnd.ms-excel')
                || file.type.match('application/pdf')
                || file.type.match('application/vnd.openxmlformats-officedocument.wordprocessingml.document')
                || file.type.match('application/vnd.openxmlformats-officedocument.presentationml.presentation')
            ) {
                uploadingFile.push(file);
            }
        });

        var myFormData = new FormData();
        uploadingFile.forEach(function (file) {
            myFormData.append('myFiles[]', file);
        });

        $.ajax({
            url: 'upload.php',
            type: 'POST',
            processData: false, // important
            contentType: false, // important
            data: myFormData,success: function(data, textStatus, jqXHR)
            {
              console.log(data);
            }
        });
    });
</script>

$target_path = "uploaded_files/";

$myFiles=$_FILES["myFiles"];
if(count($myFiles['name']) > 1){
    $total = count($myFiles['name']);
    for($i=0; $i<$total; $i++){
        $ext = explode('.',$myFiles["name"][$i]);
        $target_path = $target_path . md5(uniqid()) . "." . $ext[count($ext)-1];

        if(move_uploaded_file($myFiles["tmp_name"][$i], $target_path)) {
            echo "The file has been uploaded successfully \n";
        } else{
            echo "There was an error multiple uploading the file, please try again! \n";
        }
    }
} else {
    $ext = explode('.',$myFiles["name"]);
    $target_path = $target_path . md5(uniqid()) . "." . $ext[count($ext)-1];

    if(move_uploaded_file($myFiles["tmp_name"], $target_path)) {
        echo "The file has been uploaded successfully \n";
    } else{
        echo "There was an error uploading the file, please try again! \n";
    }
}


$（“#上传”）.change（函数（事件）{
var files=event.target.files；
var uploadingFile=[]；
文件=对象。值（文件）；
forEach（函数（文件）{
if（file.type.match（'image'））
||file.type.match（'application/vnd.ms excel'）
||file.type.match（'application/pdf'）
||file.type.match（'application/vnd.openxmlformats officedocument.wordprocessingml.document'）
||file.type.match（'application/vnd.openxmlformats of icedocument.presentationml.presentation'）
) {
uploadingFile.push（文件）；
}
});
var myFormData=new FormData（）；
uploadingFile.forEach（函数（文件）{
append（'myFiles[]，file'）；
});
$.ajax({
url:'upload.php'，
键入：“POST”，
processData:false，//重要
contentType:false，//重要
数据：myFormData，成功：函数（数据，文本状态，jqXHR）
{
控制台日志（数据）；
}
});
});

在你上传的php代码中，把代码放在下面

<script type="text/javascript">
    $("#upload").change(function (event) {
        var files = event.target.files;
        var uploadingFile = [];
        files = Object.values(files);
        files.forEach(function (file) {
            if (file.type.match('image')
                || file.type.match('application/vnd.ms-excel')
                || file.type.match('application/pdf')
                || file.type.match('application/vnd.openxmlformats-officedocument.wordprocessingml.document')
                || file.type.match('application/vnd.openxmlformats-officedocument.presentationml.presentation')
            ) {
                uploadingFile.push(file);
            }
        });

        var myFormData = new FormData();
        uploadingFile.forEach(function (file) {
            myFormData.append('myFiles[]', file);
        });

        $.ajax({
            url: 'upload.php',
            type: 'POST',
            processData: false, // important
            contentType: false, // important
            data: myFormData,success: function(data, textStatus, jqXHR)
            {
              console.log(data);
            }
        });
    });
</script>

$target_path = "uploaded_files/";

$myFiles=$_FILES["myFiles"];
if(count($myFiles['name']) > 1){
    $total = count($myFiles['name']);
    for($i=0; $i<$total; $i++){
        $ext = explode('.',$myFiles["name"][$i]);
        $target_path = $target_path . md5(uniqid()) . "." . $ext[count($ext)-1];

        if(move_uploaded_file($myFiles["tmp_name"][$i], $target_path)) {
            echo "The file has been uploaded successfully \n";
        } else{
            echo "There was an error multiple uploading the file, please try again! \n";
        }
    }
} else {
    $ext = explode('.',$myFiles["name"]);
    $target_path = $target_path . md5(uniqid()) . "." . $ext[count($ext)-1];

    if(move_uploaded_file($myFiles["tmp_name"], $target_path)) {
        echo "The file has been uploaded successfully \n";
    } else{
        echo "There was an error uploading the file, please try again! \n";
    }
}

$target_path=“uploaded_files/”；
$myFiles=$\u文件[“myFiles”]；
如果（计数（$myFiles['name']）>1）{
$total=count（$myFiles['name']）；
对于（$i=0；$i）
试试这个

})
在ajax请求之前，使用
console.log
检查
myFormData
的值。您没有看到该操作使用ajax上载文件吗？
                $("#finalupload").uploadFile({
                       url: "badocumentsupload",
                       id: "test",
                       formData: {

                       }
