What is SPAW Editor – PHP Edition?

SPAW Editor – PHP Edition is a server-side integration of the SPAW WYSIWYG editor specifically packaged for PHP applications. It provides a client-side rich-text editing experience while offering PHP-based utilities, configuration, and file management hooks that make it straightforward to integrate into PHP websites, content management systems (CMS), and custom web applications.

Key use cases:

• CMS content editing for website administrators and authors
• In-app rich-text input for forums, blogs, and e-commerce product descriptions
• Admin panels requiring formatted content input without HTML knowledge

---

Core Features

• WYSIWYG Interface: Users edit content visually with formatting tools similar to desktop word processors (bold, italic, lists, alignment, fonts).
• HTML Source Editing: Toggle between WYSIWYG and HTML source view for developers or power users.
• Image and File Management: Built-in tools for uploading and inserting images and files into content (subject to configuration).
• Customization: Configurable toolbar buttons, plugins, and editor size to match application needs.
• Cross-browser Support: Works in major browsers (with typical caveats for older browsers).
• Localization: Supports multiple languages through language files.
• Integration API for PHP: Helper classes and examples to connect the editor to PHP forms and storage backends.

Installation & Basic Integration

1. Download SPAW Editor – PHP Edition and extract to your project directory (e.g., /spaw/).
2. Include the SPAW PHP connector in your page or form. Typically, you’ll require a PHP file and call a function to render the editor instance where needed.
3. Configure the base URL and resource paths in the configuration file so the editor can find its scripts, CSS, and plugins.
4. Add the editor to a form:

   
   require_once('spaw/spaw.inc.php'); $sw = new SPAW_Wysiwyg('content', $initial_html, 'en'); $sw->show(); 

5. On form submit, the edited HTML is posted like any other form field. Sanitize before storing in a database.

Configuration Highlights

• Toolbar customization: Enable or disable buttons and groups to simplify the UI for end users.
• Editor dimensions: Set width/height to fit page layouts or create responsive behaviors.
• File manager hooks: Configure upload folders, allowed file types, and permissions.
• Language selection: Choose locale files to present controls in target languages.

Example configuration snippet (PHP):

$SPAW_ROOT = '/spaw/'; $spaw_default_config = array(   'theme' => 'default',   'toolbar' => 'complete',   'default_font' => 'Arial',   'default_font_size' => '12pt', ); 

---

Customization & Extensibility

• Create custom buttons and dialog windows to interact with application-specific features (e.g., inserting templates, shortcodes, or dynamic widgets).
• Use plugin architecture to add functionality like tables, special embeds, or integrations with media libraries.
• Modify CSS to match the editor’s appearance with your site’s theme.
• Integrate with JavaScript frameworks: SPAW outputs standard HTML so it can coexist with client-side frameworks; initialize editors in dynamic UIs carefully to avoid conflicts.

Practical example: adding a custom button to insert a predefined callout block requires editing plugin files and registering the button in the toolbar configuration.

Security Considerations

WYSIWYG editors produce raw HTML which can introduce XSS (Cross-Site Scripting) risks if user input isn’t sanitized. Best practices:

• Sanitize stored HTML on server-side before saving to the database. Use a whitelist approach (allowed tags and attributes).
• Escape or validate inputs when rendering in contexts other than HTML (e.g., attributes).
• Restrict uploadable file types and scan uploaded files for malware.
• Use proper file permissions and store uploads outside the webroot or with randomized filenames.
• Keep the editor and its plugins up to date to receive security fixes.

Common PHP libraries for sanitization:

• HTML Purifier — robust, compliant HTML filtering.
• HTMLawed — simpler, lightweight filtering.

---

Performance & Compatibility

• Lazy-load the editor scripts only on pages where editing is required to reduce initial page weight.
• For pages with many editor instances, initialize instances dynamically or reuse instances to conserve memory.
• Test across supported browsers and devices; mobile editing may require UI adjustments or alternate input mechanisms.

---

Example: Integrating with a CMS Workflow

1. Place SPAW editor in the admin “Create Post” form.
2. Configure image uploads to save under /uploads/posts/{post_id}/ and record file metadata in the database.
3. On save, sanitize content via HTML Purifier, extract and process images (resize, create thumbnails), and store final HTML in a database field.
4. When rendering posts, ensure the template does not double-escape HTML and that any user-supplied embeds are validated.

---

Troubleshooting Common Issues

• Editor assets not loading: verify correct SPAW_ROOT path and file permissions.
• Toolbar missing buttons: check toolbar configuration and plugin availability.
• Uploads failing: confirm server-side upload paths, permissions, and PHP file-upload settings (post_max_size, upload_max_filesize).
• Conflicts with other JS libraries: ensure no duplicate global variables and use noConflict patterns if needed.

Alternatives & When to Use SPAW

SPAW is suitable for projects that need a straightforward, PHP-friendly WYSIWYG editor with easy server-side integration. If you need modern features like collaborative editing, real-time collaborative cursors, or advanced embed card support, consider alternatives such as CKEditor, TinyMCE, or editor.js, depending on project requirements.

Comparison snapshot:

Feature	SPAW Editor – PHP Edition	CKEditor/TinyMCE

Conclusion

SPAW Editor – PHP Edition remains a practical choice for PHP developers seeking a traditional WYSIWYG editing experience with server-side hooks and straightforward integration. Pay particular attention to sanitization and file handling when incorporating any rich-text editor into a web application.
