Question

所以我有一个正在运行的脚本，它将脚本上传到正确的目录（由我创建），然后将图像放入该目录并重命名它们，太酷了！但是，我放置的少量显示错误文本始终会打印每个错误。因此，例如，我有$ j ++，并且由于我的错误，最大值将为$ j = 4，如果$ j = 4，则所有错误都会打印出来，并且您会认为有问题并且图像没有已上传。但是我选择了4张图像，其中3张已上传，但所有错误仍然显示。

所以我的问题是，为什么地球上会显示所有错误，为什么只上传4个图像中的3个？我希望能够一次上传30张图片...

代码

    //Image Upload Section

$j = 0; //Variable for indexing uploaded image 

    $target_path = $imagePath."/"; //Declaring Path for uploaded images
    for ($i = 0; $i < count($_FILES['file']['name']); $i++) { //loop to get individual element from the array

        $validextensions = array("jpeg", "jpg", "png"); //Extensions which are allowed
        $ext = explode('.', basename($_FILES['file']['name'][$i])); //explode file name from dot(.) 
        $file_extension = end($ext); //store extensions in the variable

        $target_path = $target_path.md5(uniqid()).
        ".".$ext[count($ext) - 1]; //set the target path with a new name of image
        $j = $j + 1; //increment the number of uploaded images according to the files in array       

        if (($_FILES["file"]["size"][$i] < 100000000) //Approx. 100000kb files can be uploaded.
            && in_array($file_extension, $validextensions)) {
            if (move_uploaded_file($_FILES['file']['tmp_name'][$i], $target_path)) { //if file moved to uploads folder
                echo $j.
                ').<span id="noerror">Image Uploaded Successfully!.</span><br/><br/>';
            } else { //if file was not moved.
                echo $j.
                ').<span id="error">Please Try Again!.</span><br/><br/>';
            }
        } else { //if file size and file type was incorrect.
            echo $j.
            ').<span id="error">***Invalid File Size or Type***</span><br/><br/>';
        }
    }

//End Image Upload Section

图片 Image of all the errors (After 3 out of 4 Images Uploaded Successfully

PS 附带说明一下，是否有一种简单的方法可以遍历目录并选择其中的所有图像，然后将它们显示为HTML？

PHP将多个图像上传到目录-失败
