同时创建文件夹和上传文件

Question

我的代码出现问题。我知道我做错了什么，但我不知道是什么。 我有一个照片上传表单，如果它不存在，它必须创建一个文件夹，然后将图片上传到该文件夹​​。

所以我的问题是 我不能同时做这两件事。 如果该文件夹已存在，则上传图片，但如果该文件夹不存在，它只会创建该文件夹，我必须再次上传该图片才能进入该文件夹。

这是我的代码。

INDEX.HTML

<form action="" method="post" enctype="multipart/form-data">
<input id="input-image-3" class="file-loading" type="file" id="file" name="files[]" multiple="multiple" accept="image/*" />
</form>

        <script>
        $("#input-image-3").fileinput({
            uploadUrl: "upload.php",
            allowedFileExtensions: ["jpg","jpeg", "png", "gif"],
            maxImageWidth: 100,
            maxImageHeight: 100,
            resizePreference: 'height',
            maxFileCount: 10,
            resizeImage: true,


        }).on('filepreupload', function() {
            $('#kv-success-box').html('');
        }).on('fileuploaded', function(event, data) {
            $('#kv-success-box').append(data.response.link);
            $('#kv-success-modal').modal('show');
        });

        </script>

UPLOAD.PHP

<?php
$valid_formats = array("jpg", "png");
$max_file_size = 1024*100; //100 kb
$path = "up/test/"; // Upload directory, later i'll get the name of user
$filename=$file['filename'];
$extension = '.jpg';
$i=1;
while(file_exists($path.$filename.$extension)){
                  $filename=$file['filename']."teste_($i)";
                 $i++;}

if(isset($_POST) and $_SERVER['REQUEST_METHOD'] == "POST"){
    // Loop $_FILES to exeicute all files
    foreach ($_FILES['files']['name'] as $f => $name) { 
        if ($_FILES['files']['error'][$f] == 4) {
            continue; // Skip file if any error found
        }          
        if ($_FILES['files']['error'][$f] == 0) {              
            if ($_FILES['files']['size'][$f] > $max_file_size) {
                $message[] = "$name is too large!.";
                continue; // Skip large files
            }
            elseif( ! in_array(pathinfo($name, PATHINFO_EXTENSION), $valid_formats) ){
                $message[] = "$name is not a valid format";
                continue; // Skip invalid file formats
            }
            else{ // No error found! Move uploaded files

                    if(!is_dir($path)){mkdir($path, 0755);} // If dont exist, create folder

                move_uploaded_file($_FILES["files"]["tmp_name"][$f], $path.$filename.$extension);    
            }    
        }
    }
}
echo json_encode (json_decode ("{}"));
?>

提前谢谢你，

尝试使用下面的代码在新创建的目录中上传文件。

<?php
    define("SITE_NAME","project_name/"); //constant for project name
    define("SITE_PATH",$_SERVER['DOCUMENT_ROOT']."/".SITE_NAME); //constant for project base directory
    define("IMAGES_URL",SITE_URL."images/"); //constant for image directory


    $upload_base_dir=IMAGES_URL;
    $upload_time_dir=date('Y')."/".date('m')."/".date('d')."/"; // setup directory name
    $upload_dir = $upload_base_dir.$upload_time_dir;

    if (!file_exists($upload_dir)) {
        mkdir($upload_dir, 0777, true);  //create directory if not exist
    }

    $image_name=basename($_FILES['image']['name']);
    $image=time().'_'.$image_name;
    move_uploaded_file($_FILES['image']['tmp_name'],$upload_dir.$image); // upload file
?>

if(!is_dir($path)){mkdir($path, 0755); 将其更改为 777 并检查是否有帮助 或者试试这个
