Add Snippet To Project
Building a readable and engaging website often involves fine-tuning small details, one of which may be adjusting the excerpt field height in WordPress. An excerpt, which provides a brief summary of your full post, plays a crucial role in engaging users, making it essential to provide sufficient space to craft it effectively. In this detailed guide, we will be showing you how to increase the excerpt field height in WordPress, enabling you to have a better view of your text as you perfect your summaries.
function wpturbo_increase_excerpt_height() {
echo '
<style type="text/css">
#excerpt { height:250px; }
</style>
';
}
add_action('admin_head', 'wpturbo_increase_excerpt_height');
The given code snippet functions to increase the height of the excerpt field in the WordPress backend. It supplements the convenience of the user by presenting a larger area to work with while editing the excerpt of a post. The detailed workings of the code are clarified below.
Firstly, a function named wpturbo_increase_excerpt_height() is defined. Within this function, an echo statement is used to display HTML and CSS code. The snippet is then hooked into the admin_head action hook available in WordPress, to ensure it gets executed in the admin dashboard's header area.
The HTML and CSS code echoed by the function, which is wrapped within style tags, targets the excerpt field of the WordPress dashboard. The ID value for the excerpt field in WordPress is excerpt, and this is precisely the element targeted in the CSS code.
The property applied to the #excerpt element is height:250px;. This CSS rule implies that the height of the excerpt text field will be increased to 250 pixels. By modifying this value, you can adjust the height of the excerpt field to fit your preferred value.
Finally, we utilize add_action('admin_head', 'wpturbo_increase_excerpt_height'); to bind our newly declared function to the admin_head action hook. WordPress action hooks allow developers to 'hook' their custom code within the WordPress lifecycle. The admin_head hook in particular is invoked in the <head> section of the admin side of the WordPress site.
In this case, the wpturbo_increase_excerpt_height function declared previously gets attached to the admin_head action hook, causing it to execute every time the admin dashboard is accessed. This results in the height of the "Excerpt" field being increased as specified whenever a WordPress administrator is writing or editing a post in the admin dashboard.
