Introduction to InstantCMS templates

InstantCMS templates are located in subcategories of the /templates/ directory. The template directory may contain CSS tables, JavaScript files, files of output templates, helper function file, template options form and various images. For instance, the template called «test» is located in the /templates/test/ directory.

There is the «default» template in InstantCMS by default. For a better understanding of how to create a custom template, carefully examine the files it contains.

InstantCMS does not use any template engine like Smarty or Twig. All code is written in PHP. The main purpose of InstantCMS templates is to separate presentation from logic.

What kind of template files can be?

Under template files we assume certain files with the .tpl.php double extension. In other words, the files are ordinary PHP files, while the second .tpl extension indicates the template file. In the full title of the file, anything that comes before .tpl.php is the template title. For example, a file is called index.tpl.php - the engine will operate with the index name only.

An InstantCMS template consists of a common layout (there can be more than one) and output files-templates.

A common layout is the main template of all site pages and contains the <html>, <head> and <body> tags. The templates of components and widgets are output inside it. By default, the engine uses two layouts: main.tpl.php for the site and admin.tpl.php for the Control panel.

Output template files are intended to display the work results of controllers, widgets or other subsidiary actions, for example, error messages, output of form fields.

A list of standard template files and directories

The path to the files from the tables below is specified relative to the template’s root directory, i.e., if a template is located in the /templates/test/ directory, the paths below are specified relative to /templates/test/.

How the engine works with template files

There is an inheritance mechanism of template files in InstantCMS. This means that when linking a relevant template file, css and javascript files, the engine searches it in the current template first and then in other templates, if the inheritance chain is specified. The default template is always the root of the chain. Read more about the inheritance mechanism here.
