Simple Login Customize

Simply customize your admin login page using this plugin.

FAKTOR VIER

With <a href="https://www.f4dev.ch" rel="nofollow ugc">F4 Simple White Label</a> you can change the login image, add a custom logo to the admin bar and change the admin footer texts.
Currently this is only possible with a few easy to use hooks. We plan to add an options page to the WordPress backend, so you can change all the above mentioned without using a single line of code.
<h4>Usage</h4>
You can add the following hooks to the functions.php of your theme.
Add favicon to login page and backend:
<pre><code>add_filter('F4/SWL/admin_favicon', function() {
 return 'url-to-your-favicon.ico';
});
</code></pre>
Change the login page image:
<pre><code>add_filter('F4/SWL/login_image', function() {
 return 'url-to-your-login-image.png';
});
</code></pre>
You can also change the href, link text, image alt text like this:
<pre><code>add_filter('F4/SWL/login_image_href', function() {
 return 'https://www.f4dev.ch';
});

add_filter('F4/SWL/login_image_link_text', function() {
 return 'This WordPress is powered by FAKTOR VIER';
});

add_filter('F4/SWL/login_image_alt', function() {
 return 'FAKTOR VIER logo';
});
</code></pre>
If needed you can add custom inline styles to the image:
<pre><code>add_filter('F4/SWL/login_image_style', function() {
 return 'width:50px; height:50px;';
});
</code></pre>
Add a custom logo to the admin bar:
<pre><code>add_filter('F4/SWL/admin_bar_logo', function() {
 return 'url-to-your-admin-bar-logo.png';
});
</code></pre>
You can also change the href, logo alt text like this:
<pre><code>add_filter('F4/SWL/admin_bar_logo_href', function() {
 return 'https://www.f4dev.ch';
});

add_filter('F4/SWL/admin_bar_logo_alt', function() {
 return 'FAKTOR VIER logo';
});
</code></pre>
If needed you can add custom inline styles to the logo:
<pre><code>add_filter('F4/SWL/admin_bar_logo_style', function() {
 return 'height:20px; margin:8px 0;';
});
</code></pre>
If you have users that like to use the light color theme, you can define a different logo for that. If you dont use this hook, the admin_bar_logo logo us used for all themes:
<pre><code>add_filter('F4/SWL/admin_bar_logo_light', function() {
 return 'url-to-your-admin-bar-logo-light.png';
});
</code></pre>
Change the backend footer texts:
<pre><code>add_filter('F4/SWL/admin_footer_text', function() {
 return 'Thank you for creating with WordPress.Get';
});

add_filter('F4/SWL/admin_footer_update_text', function() {
 return 'Version 5.3';
});
</code></pre>
