Make blog entry slug editable for SEO optimization

[Copilot]

The slug field was disabled, preventing users from customizing URLs for SEO. The field now auto-generates on creation but allows manual editing, with subsequent title changes not overwriting manual edits. Custom slugs are now properly reflected in frontend URLs.

Changes

Template (werkl-cms-sidebar.html.twig)

• Removed disabled attribute from slug input field

Controller Logic (werkl-blog-detail/index.js)

• Added state tracking: slugManuallyEdited, autoGeneratedSlug, isAutoGenerating
• Modified generateSlug() to set isAutoGenerating flag during updates, storing result in autoGeneratedSlug
• Updated slug watcher to detect manual edits only when not auto-generating and value differs from autoGeneratedSlug
• Modified onBlogTitleChanged() to skip auto-generation when slug is manually edited
• Set slugManuallyEdited=true when loading existing entries to preserve URL stability

SEO URL Route (BlogSeoUrlRoute.php)

• Changed DEFAULT_TEMPLATE to use entry.translated.slug instead of entry.translated.title
• Ensures that custom slugs are used when generating frontend URLs

Migration (Migration1735580257UpdateSeoUrlTemplateToUseSlug.php)

• Updates the SEO URL template in the database to use slug instead of title
• Handles both old template format (blog/{{ entry.translated.title|lower }}) and new format (blog/{{ entry.blogCategories.first.translated.name|lower }}/{{ entry.translated.title|lower }})
• Triggers automatic regeneration of all blog entry SEO URLs when the plugin is updated
• Ensures existing installations get the updated template

Behavior

New entries: Slug auto-generates from title. Manual edits stop auto-generation. Frontend URLs use the custom slug.

Existing entries: Slug remains stable regardless of title changes. Manual edits allowed anytime. Frontend URLs update to reflect the custom slug.

Installation/Update Instructions

After updating to this version:

1. Run bin/console system:update --finish to execute the migration
2. All SEO URLs for blog entries will be regenerated to use the slug field
3. Old URLs will remain as redirects (Shopware's default behavior)
4. New custom slugs will immediately work in the frontend

// Title change triggers auto-generation only if not manually edited
if (!this.blog.slug || !this.slugManuallyEdited) {
    this.generateSlug(blogTitle);
}

// SEO URL template now uses slug instead of title
'blog/{{ entry.blogCategories.first.translated.name|lower }}/{{ entry.translated.slug|lower }}'

<issue_title>Feature Request: Slug bearbeitbar machen</issue_title>
<issue_description>SEO-Technisch ist es meist nicht so toll, den Slug genau wie den Beitragstitel aufzubauen.
Bearbeitbar wäre klasse. Also beim Anlegen automatisch generieren, dann aber zur Bearbeitung freigeben.</issue_description>

Editing the slug in the backend works, but in the frontend the new url does not work.

Fixed in commit 0e10d73. The issue was that the SEO URL template was using entry.translated.title instead of entry.translated.slug.

Changed the DEFAULT_TEMPLATE in BlogSeoUrlRoute.php to use the slug field:

'blog/{{ entry.blogCategories.first.translated.name|lower }}/{{ entry.translated.slug|lower }}'

Now when you edit the slug in the backend and save, the SEO URL will be regenerated using your custom slug, and the frontend URL will work correctly.

@copilot In frontend I still get NotFoundHttpException if I enter the new url manually into the address bar and the links on the blog listing page also still link to the old slug.

Fixed in commits 5c9b671 and 5a76740.

The issue was that changing the code constant doesn't update the database. Created a migration that updates the SEO URL template in the database to use the slug field instead of title.

The migration handles both template formats:

• Old: blog/{{ entry.translated.title|lower }} → blog/{{ entry.translated.slug|lower }}
• New: blog/.../{{ entry.translated.title|lower }} → blog/.../{{ entry.translated.slug|lower }}

After running bin/console system:update --finish, all blog entry SEO URLs will be regenerated to use the slug field. This will make the custom slugs work in the frontend, and the links on listing pages will use the new slugs.
