如何为WordPress批量设置博客文章302重定向至子域名新站点

Got it, let's tackle this problem efficiently—no need to slog through 200+ manual redirects. Here are three solid, low-effort solutions tailored exactly to your needs (keeping pages on the main site, auto-redirecting only blog posts to the subdomain):

If you don’t want to mess with code or server files, this is your best bet. Plugins like Redirection (a widely used, reliable option) let you batch-create redirects in minutes:

• Install and activate the plugin on your main WordPress site.
• Head to the plugin’s settings page, then navigate to the Import/Export tab.
• First, export your main site’s blog post URLs: Use WordPress’s built-in Tools > Export to download an XML file of just your posts (uncheck the "Pages" box).
• Open the XML file, extract all post permalinks (look for <link> tags pointing to your main site’s posts).
• Back in the Redirection plugin, use the Add Redirects bulk tool: Paste the list of old URLs, then set the target URL pattern to replace your main domain with blog.sitename.com (e.g., swap https://sitename.com/ for https://blog.sitename.com/).
• Set the redirect type to 302 Temporary (as you specified).
• Bonus: The plugin lets you add a condition to only apply redirects to the "Post" content type, so pages are automatically excluded—no accidental redirects.

If you have access to your site’s .htaccess file (usually in the root folder of your main site), this method is lightning-fast because it works at the server level before WordPress even loads.
First, backup your .htaccess file (critical in case something goes wrong). Then add these rules above the WordPress-generated # BEGIN WordPress section:

# Redirect only blog posts to subdomain (302 temporary)
RewriteEngine On
# Exclude specific pages (add more lines for additional pages you want to keep on main site)
RewriteCond %{REQUEST_URI} !^/about/
RewriteCond %{REQUEST_URI} !^/contact/
# Match date-based post URLs (adjust regex if your post structure is different)
# Example: Matches URLs like /2024/05/my-blog-post/
RewriteRule ^([0-9]{4}/[0-9]{2}/.+)$ https://blog.sitename.com/$1 [R=302,L]

• If your posts use a different URL structure (e.g., /post/my-blog-post/), update the RewriteRule regex to ^post/(.+)$ instead.
• The [R=302] flag sets the temporary redirect, and [L] tells the server to stop processing further rules once this one matches.
• This ensures only posts get redirected—pages you exclude stay on the main site.

If you’re comfortable editing your theme’s code (use a child theme to avoid losing changes when updating your theme), this method lets you target posts directly without any plugins:
Add this code to your child theme’s functions.php file (or use a code snippet plugin):

// Redirect single blog posts to subdomain (302 temporary)
add_action('template_redirect', 'redirect_posts_to_subdomain');
function redirect_posts_to_subdomain() {
    // Check if we're on a single blog post (not a page, archive, etc.)
    if (is_single() && get_post_type() === 'post') {
        // Get the current post's permalink
        $old_url = get_permalink();
        // Replace main domain with subdomain
        $new_url = str_replace('https://sitename.com/', 'https://blog.sitename.com/', $old_url);
        // Perform 302 redirect
        wp_redirect($new_url, 302);
        exit;
    }
}

• This code runs every time a page loads. It checks if the current request is a single blog post, swaps the domain part of the URL, and redirects immediately.
• Pages, archives, and other content types are completely ignored—perfect for your use case.
• Remember to replace sitename.com with your actual domain.

Quick Recommendation #

• If you’re not technical: Go with the plugin method—it’s straightforward and lets you manage redirects later if needed.
• If you want maximum performance: Use the .htaccess rule.
• If you want full control without plugins: Use the custom function.
