Question

我很高兴为wordpress编写插件。

我正在寻找一个用户可以上传图像的插件，并且某个样式（在后端编码）应用于图像。然后我会允许用户使用短代码输入图像。

（以上只是我需要做的一个例子......它比这更复杂但是我确定我可以在开始时编写代码）

所以我可以做的短代码。

首先，我将如何创建一个可以上传图像的管理面板，并将该图像存储在数据库中。

当用户上传图像时，前一张图像将被覆盖。

如果某人有一个关于创建管理面板的好教程的链接，那就太棒了。那些人只是不适合我。

这是另一个好的开始：http://codex.wordpress.org/Writing_a_Plugin

这段代码可以帮到你：

yourPlugin.php

<?php
/*
Plugin Name: Name Of The Plugin
Plugin URI: http://URI_Of_Page_Describing_Plugin_and_Updates
Description: A brief description of the Plugin.
Version: The Plugin's Version Number, e.g.: 1.0
Author: Name Of The Plugin Author
Author URI: http://URI_Of_The_Plugin_Author
License: A "Slug" license name e.g. GPL2
*/

*/

$object = new YourPlugin();

//add a hook into the admin header to check if the user has agreed to the terms and conditions.
add_action('admin_head',  array($object, 'adminHeader'));

//add footer code
add_action( 'admin_footer',  array($object, 'adminFooter'));

// Hook for adding admin menus
add_action('admin_menu',  array($object, 'addMenu'));

//This will create [yourshortcode] shortcode
add_shortcode('yourshortcode', array($object, 'shortcode'));

class YourPlugin{

    /**
     * This will create a menu item under the option menu
     * @see http://codex.wordpress.org/Function_Reference/add_options_page
     */
    public function addMenu(){
        add_options_page('Your Plugin Options', 'Your Plugin', 'manage_options', 'my-unique-identifier', array($this, 'optionPage'));
    }

    /**
     * This is where you add all the html and php for your option page
     * @see http://codex.wordpress.org/Function_Reference/add_options_page
     */
    public function optionPage(){
        echo "add your option page html here or include another php file";
    }

    /**
     * this is where you add the code that will be returned wherever you put your shortcode
     * @see http://codex.wordpress.org/Shortcode_API
     */
    public function shortcode(){
        return "add your image and html here...";
    }
}
?>

将此代码添加到yourPlugin.php文件中，并将其放在插件目录中。 E.g plugins/yourPlugin/yourPlugin.php

Answer 2

在插件中添加以下内容应该可以帮助您入门

/*****Options Page Initialization*****/
// if an admin is loading the admin menu then call the admin actions function
if(is_admin()) add_action('admin_menu', 'my_options');
// actions to perform when the admin menu is loaded
function my_options(){add_options_page("My Options", "My Options", "edit_pages", "my-options", "my_admin");}
// function called when "My Options" is selected from the admin menu
function my_admin(){include('admin-options.php');}

然后，您将使用管理页面演示和功能创建名为admin-options.php的文件。在该文件中尝试“Hello World”只是为了看到它。

此代码在WordPress Codex http://codex.wordpress.org/Adding_Administration_Menus中有详细解释，它还将为您提供一些如何以标准方式正确构建页面的示例。
