<p>Safe Headers Scanner helps WordPress administrators identify common issues that may cause header-related problems.<br />
The plugin scans installed themes and plugins for:<br />
* Unnecessary whitespace before <code><?php</code> tags<br />
* Extra whitespace after closing <code>?></code> tags<br />
* Direct output (e.g., <code>echo</code>, <code>print</code>) before headers are sent</p>
<p>Results are displayed in a clear report, so you can review and fix potential issues easily.</p>


Safe Headers Scanner

Scan themes and plugins for potential header issues such as whitespace before/after PHP tags or direct output before headers.

<p>This plugin has been actively maintained since 2012 and is used on over 20,000 websites worldwide.</p>
<h4>Features</h4>
<p>The <a href="https://geek.hellyer.kiwi/products/unique-headers/" rel="nofollow ugc">Unique Headers Plugin</a> adds a custom header image box to the post/page edit screen. You can use this to upload a unique header image for that post, or use another image from your WordPress media library. When you view that page on the front-end of your site, the default header image for your site will be replaced by the unique header you selected.</p>
<p>This functionality also works with categories and tags.</p>
<h4>Requirements</h4>
<p>You must use a theme which utilizes the built-in custom header functionality of WordPress. If your theme implement it’s own header functionality, then this plugin will not work with it.</p>

<h3>Development</h3>
<p>This section is only relevant for developers building the plugin from source (e.g. cloning from GitHub). If you installed via WordPress.org, the plugin is ready to use — no build steps required.</p>
<p>The plugin uses Composer for PHP autoloading and dependencies, npm for JavaScript tooling, and TypeScript for admin JavaScript.</p>
<p>To set up a development environment:</p>
<ol>
<li>Install PHP dependencies: <code>composer install</code></li>
<li>Install JavaScript dependencies: <code>npm install</code></li>
<li>Compile TypeScript to JavaScript: <code>npm run build</code></li>
</ol>
<p>To run tests and analysis:</p>
<ul>
<li>PHPCS (PSR-12 coding standards): <code>composer phpcs</code></li>
<li>Auto-fix PHPCS violations: <code>composer phpcbf</code></li>
<li>PHP-CS-Fixer (dry-run): <code>composer cs</code></li>
<li>PHP-CS-Fixer (auto-fix): <code>composer cs:fix</code></li>
<li>PHPStan static analysis: <code>composer phpstan</code></li>
<li>PHPUnit unit tests: <code>composer test</code></li>
<li>TypeScript type checking: <code>npm run typecheck</code></li>
</ul>
<p>TypeScript source files are in <code>src/ts/</code>. The compiled output is written to <code>assets/admin.js</code> and is what WordPress loads on the admin side.</p>

Unique Headers

Great plugin!

Use it on every site. Why would soneone like to have the same header on every page? Should be in core. =)

Should have been core since .. ever?

Add unique custom header images to individual pages, posts, categories, or tags.
