求教：在WordPress后台新增页面/文章时添加按钮（链接）的Hook指引

Hey there! I’ve got you covered on adding that custom HTML button (link) to the WordPress post/page creation screen. Here are two reliable hooks you can use, depending on where you want the button to appear:

Option 1: Add Button to the Publish Sidebar (Miscellaneous Section) #

The post_submitbox_misc_actions hook is perfect if you want the button near the publish/update controls—it blends seamlessly with the existing admin UI.

Code Example: #

add_action('post_submitbox_misc_actions', 'add_custom_publish_sidebar_button');
function add_custom_publish_sidebar_button() {
    global $post;

    // Only show the button on NEW post/page screens (auto-draft status means it's a fresh entry)
    if ($post->post_status === 'auto-draft') {
        ?>
        <div class="misc-pub-section">
            <a href="https://your-target-url.com" target="_blank" class="button button-primary">
                Click Me! (Custom Button)
            </a>
        </div>
        <?php
    }
}

Breakdown: #

• Hook Usage: post_submitbox_misc_actions renders your content in the sidebar area below the "Visibility" and "Publish" options.
• Conditional Check: $post->post_status === 'auto-draft' ensures the button only shows when creating a new post/page (not editing existing ones). Remove this line if you want it visible on edit screens too.
• Styling: Using WordPress built-in classes (button, button-primary) ensures the button matches the admin theme’s style.

Option 2: Add Button Below the Post/Page Title #

If you prefer the button to sit right under the title field (above the content editor), use the edit_form_after_title hook.

Code Example: #

add_action('edit_form_after_title', 'add_custom_button_below_title');
function add_custom_button_below_title() {
    global $post;

    if ($post->post_status === 'auto-draft') {
        ?>
        <div style="margin: 15px 0;">
            <a href="https://your-target-url.com" target="_blank" class="button button-secondary">
                My Custom Link Button
            </a>
        </div>
        <?php
    }
}

Where to Put This Code: #

• Theme Functions: Add the code to your active theme’s functions.php file (note: changes here may be overwritten if you update the theme).
• Custom Plugin: For a more permanent solution, create a simple custom plugin:

  /*
  Plugin Name: Custom Edit Screen Button
  Description: Adds a custom button to WordPress post/page creation screens
  Version: 1.0
  Author: Your Name
  License: GPL2
  */
  
  // Paste your chosen button function here (either Option 1 or 2)
  

Just replace https://your-target-url.com with your actual link, and tweak the button text to fit your needs!
