循环文件数组未上传所有文件

Question

    我试图根据用户上传的内容上传 1 - x 数量的文件。最近，我创建了一个 for 循环来遍历文件。我所看到的只是第一个文件上传。

有谁知道为什么只有第一个文件会上传？

class fileUpload

{

    public function __construct()

    {}

    public function upload() {

        $file_count = count($_FILES['uploadedFile']['name']);

        //$file_count = count($_FILES($file_post['name']));

        for ($i = 0; $i<$file_count; $i++) {

//          echo $file['uploadedFile']['name'][$index] . "\n";

            $target_dir = "uploads/";

            $target_file = $target_dir . basename($_FILES["uploadedFile"]["name"][$i]);

            $uploadOk = 1;

            $imageFileType = strtolower(pathinfo($target_file, PATHINFO_EXTENSION));        

            // Check if $uploadOk is set to 0 by an error

            if ($uploadOk == 0) {

                return 0;

    // if everything is ok, try to upload file

            } else {

                if (move_uploaded_file($_FILES["uploadedFile"]["tmp_name"][$i], $target_file)) {

                    return basename($_FILES["uploadedFile"]["name"][$i]);

                } else {

                    return 0;

                }

            }

        }

    }

}

表单输入：

<input type="file" name="uploadedFile[]" class="inputfile" id="uploadedFileTest" data-multiple-caption="{count} files selected" multiple>

Answer 1

那是因为您使用return,return将使您退出该功能，并且您只会获得上传的第一个项目。一个简单的解决方法是：if (!move_uploaded_file($_FILES["uploadedFile"]["tmp_name"][$i], $target_file)) {&nbsp; &nbsp; return 0;}//更新2个解决方案的建议public function upload() {&nbsp; &nbsp; &nbsp; &nbsp; $file_count = count($_FILES['uploadedFile']['name']);&nbsp; &nbsp; &nbsp; &nbsp; //$file_count = count($_FILES($file_post['name']));&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; // add a array to save the basename on each loop&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $results = [];&nbsp; &nbsp; &nbsp; &nbsp; for ($i = 0; $i<$file_count; $i++) {//&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; echo $file['uploadedFile']['name'][$index] .
