Rendering Elements in CakePHP 3: A Guide to Efficiently Use Elements in Your CakePHP 3 Applications

Rendering elements in CakePHP 3 allows developers to break down their views into reusable components, promoting clean and maintainable code. Elements are particularly useful for code that is repeated across multiple views, such as headers, footers, or forms.

You can also pass variables to elements to customize their output further. For instance:

Creating an Element

To create a new element, navigate to the src/Template/Element directory of your CakePHP application. Here, you can create a new file, such as footer.ctp, and add your HTML and PHP code that you want to reuse.

Using Elements in Layouts

Elements can also be used in layout files, making it easy to incorporate reusable components throughout your application. Simply use the same $this->element() method within your layout files.
