Question

您好我有一个简单的表单并实现了一个ajax脚本。我的问题是如何从另一个php文件显示echo消息，即user-file-upload.php？

我还想问我是否正在以正确的方式做ajax。我现在是ajax中的一个总noob。希望你能帮助我朝着正确的方向前进。感谢

这是我的表格

this.$el.on

这是user-file-upload.php

 echo "<form action='portal-files/user-file-upload.php' method='post' enctype='multipart/form-data' id='test_ajax'>";
    echo "<input type='hidden' name='MAX_FILE_SIZE' value='100000' />";
    echo "<input type='hidden' name='admin_id' value='$user->id' />";
    echo "<select name='id' id='form-option' class='test-only'>";
    echo '<option selected="selected">' .'Choose a User'. '</option>';

    foreach ($registeredUsers as $key => $value) {
      $registered = JFactory::getUser($value);
      echo '<option value="'.$registered->id.'">'.$registered->name.'</option>';

    }
    echo "</select>";
    echo "<input name='uploadedfile' type='file' id='custom-file-input' class='test-only' /> <br/>";
    echo '<input type="submit" name="submit" value="Upload" id="custom-submit-input" disabled="disabled" >';
    echo '<span id="display_file"></span>';
    echo '<span id="display_user" style="visibility:hidden"></span>';
    echo "</form>";

这是我的jquery脚本

<link rel="stylesheet" type="text/css" href="https://cdn.rawgit.com/t4t5/sweetalert/master/dist/sweetalert.css">

$target_dir = "../portal-files/";
$target_file = $target_dir . basename($_FILES["uploadedfile"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);



// Check if file already exists

    echo "Sorry, file already exists.";
    $uploadOk = 0;
}

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

            $selectedValue = $_POST['id'];
            $adminabc = $_POST['admin_id'];

            $imageFileName = basename( $_FILES["uploadedfile"]["name"]);



            $db = JFactory::getDbo();
            $query = $db->getQuery(true);

            $query = "INSERT INTO joom_fss_user_files (user_id,admin_id) VALUES ($selectedValue,$adminabc)";

            $db->setQuery($query);

            $db = JFactory::getDbo();
            $query_user = $db->getQuery(true);

            $query_user = "INSERT INTO joom_fss_files (user_id,admin_id,file_type,file_name,path_url) VALUES ($selectedValue,$adminabc,'$imageFileType','$imageFileName', '$target_file')";

            $db->setQuery($query_user);
            $result = $db->execute();

            sweetAlert("You have successfuly uploaded a file."); 

        }


    } else {
        echo "Sorry, there was an error uploading your file.";
    }
