Question

在这个PHP代码中，我想自定义图像上传目的地。有了这个php文件，我有一个名为uploads的目录。我想将我上传的所有图像添加到此目录并在db中存储路径。我怎么能这样做？

<?php
// Assigning value about your server to variables for database connection
$hostname_connect= "localhost";
$database_connect= "image_upload";
$username_connect= "root";
$password_connect= "";

$connect_solning = mysql_connect($hostname_connect, $username_connect, $password_connect) or trigger_error(mysql_error(),E_USER_ERROR); 
@mysql_select_db($database_connect) or die (mysql_error()); 

if($_POST) { 
    // $_FILES["file"]["error"] is HTTP File Upload variables $_FILES["file"] "file" is the name of input field you have in form tag.

    if ($_FILES["file"]["error"] > 0) {
        // if there is error in file uploading 
        echo "Return Code: " . $_FILES["file"]["error"] . "<br />";

    } else {
        // check if file already exit in "images" folder.
        if (file_exists("images/" . $_FILES["file"]["name"])) {
            echo $_FILES["file"]["name"] . " already exists. ";
        } else {  
            //move_uploaded_file function will upload your image.  if you want to resize image before uploading see this link http://b2atutorials.blogspot.com/2013/06/how-to-upload-and-resize-image-for.html
            if(move_uploaded_file($_FILES["file"]["tmp_name"],"images/" . $_FILES["file"]["name"])) {
                // If file has uploaded successfully, store its name in data base
                $query_image = "insert into acc_images (image, status, acc_id) values ('".$_FILES['file']['name']."', 'display','')";
                if(mysql_query($query_image)) {
                    echo "Stored in: " . "images/" . $_FILES["file"]["name"];
                } else {
                    echo 'File name not stored in database';
            }
       }
   }    
}
}
?>

目前我运行上传时我收到了警告

警告：move_uploaded_file（images / 1409261668002.png）：无法打开流：第29行的D：\ xampp \ htdocs \ image-upload \ index.php中没有此类文件或目录

警告：move_uploaded_file（）：无法在第29行的D：\ xampp \ htdocs \ image-upload \ index.php中将'D：\ xampp \ tmp \ php1C1F.tmp'移动到'images / 1409261668002.png'

Answer 1

您必须指定正确的路径，如果您不创建'images/1409261668002.png'路径并且未指定它们，则if(move_uploaded_file($_FILES["file"]["tmp_name"],"images/" . $_FILES["file"]["name"]))) { .... }路径不存在。

SELECT SUBSTRING(Username, CHARINDEX('/', Username) + 1, LEN(Username)), UserType
FROM USERS_DATABASE;

您必须指定绝对路径

Answer 2

您可以使用以下代码：

$image=basename($_FILES['file']['name']);
$image=str_replace(' ','|',$image);

$tmppath="images/".$image;
if(move_uploaded_file($_FILES['file']['tmp_name'],$tmppath))
{...}
