Question

我创建了一个脚本，以便一个人将文本信息和图片上传到数据库。图片托管在名为“images”的网站的子文件夹中。

我面临的问题是该文件夹正在上传到该文件夹，但文件名未记录在数据库中。

我知道这不是连接问题，因为文件字段被记录在数据库中，而文件名被留作空白。

我认为这可能是我的checkUpload（）方法的一个问题。

这是我的整体剧本

<?php
printForm();
//when "submit" tie together values and variables
if($_POST['submit']=="Submit"){
    $email = cleanData($_POST['email']);
    $first = cleanData($_POST['first']);
    $last = cleanData($_POST['last']);
    $status = cleanData($_POST['status']);
    //$image = cleanData($_POST['image']);
    //echo "Data cleaned";
    addData($email, $first, $last, $status);
}
else{
    //printForm();
}


function checkUpload(){
    //check for uploaded files
    if(isset($_FILES['upload'])){ //upload refers to form element "upload"
        $allowed = array ('image/pjpeg', 'image/jpeg', 'image/JPG', 'image/X-PNG', 'image/PNG', 'image/png', 'image/GIF');
        if(in_array($_FILES['upload']['type'], $allowed)){//if upload if in the allowed array 'file types'
            echo "uploading files...";
            //move the file over
            if(move_uploaded_file($_FILES['upload']['tmp_name'], "images/{$_FILES['upload']['name']}")){
                //moveuf method moves to tmp folder then moves to final location
                echo "<p>The file has been uploaded 'dude'</p>";
                $image="{$_FILES['upload']['name']}";

            }//end of moving DAT IMG :3
            else{
                echo '<p>Please upload a  JPEG, GIF or PNG image.<strong>';


                if($FILES['upload']['error'] > 0){
                echo '<b>The file could not be updated because</b>';
                switch($_FILES['upload']['error']){//standard error casee
                    case 1:
                        echo 'The file exceeds the upload_max_filesize setting in php.ini';
                        break;

                        echo 'The file only partially uploaded';
                        break;
                    case 4:
                        echo 'The no file was uploaded';
                        break;

                        break;
                    default:
                        echo 'A system error occurred';
                        break;
                    }
                echo '</strong></p>';
                }
                //if the file is still in the temporary folder "unlink" which is basically just deleting the SOB
                if(file_exists($_FILES['upload']['tmp_name']) && is_file($_FILES['upload']['tmp_name'])){
                    echo 'File exists! :D';
                    unlink ($_FILES['upload']['tmp_name']);
                }
                return $image;
                //gives back image where the function was called
            }
        }

//cleans information

    if(!$status){ //everything except for status take out spaces
        $data = trim($data);

        </div>
        </form>

}

include("footer.php");
?>

另外 - 作为旁注，在我的上一篇文章中，我被告知mysqli已经成功完成了mysql。我已经注意到一些函数中的几乎完全语法，我可以在其中添加一个i到“ MySQL的“;但是，在某些功能中，情况并非如此。但是，如果我要使用相同的mysql函数，将它们更改为mysqli，是否有必要对脚本进行任何重大更改？

谢谢。

嗨，我认为你需要一个大的重新分解。但为了使其工作，将以下块代码移动到move_uploaded_file返回true的位置，并在返回false时返回null

if(file_exists($_FILES['upload']['tmp_name']) && is_file($_FILES['upload']['tmp_name'])){ echo 'File exists! :D'; unlink ($_FILES['upload']['tmp_name']); } return $image; //gives back image where the function was called

图像上传到文件夹而不是DB
