php - 上传图像并在服务器 WORDPRESS 中检索

Question

我正在尝试在服务器中上传图像并检索。
我已经做了一些事情，但问题是图像没有上传。我的脚本只会获取文件名，然后图像将保存在服务器文件夹中。这个脚本只保存其他数据，但不保存图像，我不确定哪里出错了，但我使用的路径是正确的，而且我需要检索图像并将其发布到前端。

 <div class="wrap">
              <form method="POST">
                    Date: <input type="text" name="class_date"> <br>
                    Event: <input type="text" name="class_name"><br>
                    <input type="hidden" value="class_sched" name="posttitle"><br>

                    <input type="hidden" name="size" value="350000">
                    Image:<input type="file" name="class_image"><br> 
                    <input type="submit" value="submit" name="submit">
              </form>  

        </div>      

    <?php

    global $wpdb;

        if(isset($_POST['submit']))
        {

            $target = plugins_url("/images",__FILE__);
            $target = $target . basename( $_FILES['class_image']['name']);

            $class_date = $_POST['class_date'];
            $class_name = $_POST['class_name'];
            $class_image = ($_FILES['class_image']['name']);

            $wpdb->insert('wp_calendar', array('class_name'=> $class_name, 'class_date'=>$class_date, 'class_image'=>$class_image));

             //Writes the photo to the server
            if(move_uploaded_file($_FILES['class_image']['tmp_name'], $target))
            {

                //Tells you if its all ok
                echo "The file ". basename( $_FILES['class_image']['name']). " has been uploaded, and your information has been added to the directory";
            }
            else 
            {

                //Gives and error if its not
                echo "Sorry, there was a problem uploading your file.";
            }       

        }

Answer 1

添加move_uploaded_file函数。在上面的代码中，仅检查 move_uploaded_file 是否为 true。因为这是if语句。

在 $wpdb->insert('wp_calendar', .... 后面添加以下代码

move_uploaded_file($_FILES['class_image']['tmp_name'];

move_uploaded_file 函数会将文件从临时文件夹移动到插件/图像文件夹。
