Templates are just a group of XML, PHP, HTML and image files that are stored in the templates directory of your site. You can edit these files directly or use the Template Manager.

Contents

Before You Begin

Before you start hacking away at a default installed template or any other template you may have installed, remember that any updates of the Joomla core files may contain new copies of the default Joomla templates. Similarly, editing an installed template means you may have to re-install it to reset it to the original state at installation.

Unless you take steps to protect your work, modifications could be lost when upgrading Joomla. Likewise, you may want to preserve an installed template in case you have any problems with modifications to it.

There are options in the Template Manager to Duplicate and Copy an existing template style or the actual template and template files. This page refers to the methods available to make a full copy of your template. This includes the style and all the template files of a template.

A Tip!

Template Style and Template copying are not the same. You can make a copy of the template style but you are not protected from overwriting the actual template files. Style copying simply adds another entry made in the _template_styles table of the database. This is useful is you want to check a web site design with different fonts, colors, widths or logos if these template style parameters exist. The template files are not duplicated into another uniquely-named directory and they will be overwritten during an upgrade.

Copy the Template

To preserve your changes you need to Copy the template with all its files and styles. This procedure makes references to creating a full copy (an exact duplicate) of the template including all the files. In order to make a copy, you must be on the Customise Template view. There are two methods available for accessing the Template Manager: Customise Template. The Customise Template interface allows for editing the actual code found in the template files, creating template overrides and template file manipulation.

One-Click or Switch to Template View

Styles column refers to changing the available parameters of a template, such as color, font-color, logo, etc. These are dependent on the parameters a template maker made available and are a convenience for quick changes. Template - column refers to editing the actual template files.

To access the Template Customise feature:

  • Directly - Click the template name in the column Template
600
  • Indirectly - Styles will be highlighted, click on Templates below it which will turn the view to Template Manager:Templates, see image below.

  • Select the template you wish to modify which will change the view to Template Manager: Customise Template view

Customisation View

You should now be looking at the image below, Template Manager: Customise Template.

Copy an Existing Template

The Easy Way

Create a new template by copying an existing template:

3x-template-manager-customise-template-toolbar.png
  • Provide a new name and click on Copy Template
3x-template-manager-customise-template-popup-copy.png
  • The template is completely copied. This includes styles and all the template files.

Manually

  • Create a new /templates/my_template directory.
  • Copy the contents of the original template directory to the my_template directory.
  • Go to the root /language/en-GB directory.
    • Copy /language/en-GB/en-GB.tpl_original_template.ini to en-GB.tpl_my_template.ini
    • Copy /language/en-GB/en-GB.tpl_original_template.sys.ini to en-GB.tpl_my_template.sys.ini
  • Go to the /language/en-GB directory in the template's directory, if it exists.
    • Copy /language/en-GB/en-GB.tpl_original_template.ini to en-GB.tpl_my_template.ini
    • Copy /language/en-GB/en-GB.tpl_original_template.sys.ini to en-GB.tpl_my_template.sys.ini
  • Open the templateDetails.xml file in the my_template directory and change all references, if they exist, for the original template directory to the new directory my_template.
<name>My_Template</name>
<language tag="en-GB">en-GB.tpl_my_template.ini</language>
<language tag="en-GB">en-GB.tpl_my_template.sys.ini</language>
<param name="theme_header" type="folderlist" directory="templates/my_template/styles/header" default="" label="Header Themes" description="HEADER THEMES DESCRIPTION" />
<param name="theme_background" type="folderlist" directory="templates/my_theme/styles/background" default="" label="Background Themes" description="BACKGROUND THEMES DESCRIPTION" />
<param name="theme_elements" type="folderlist" directory="templates/my_theme/styles/elements" default="" label="Primary Elements" description="PRIMARY ELEMENTS DESCRIPTION" />

Discover the New Template

When manually copying a template, the new template must be introduced to your Joomla site through the discovery process.

  • Go to Administrator  Extensions  Extension Manager  Discover
  • Click the Discover icon.
  • Select your new template.
  • Click Install.

If successful, the new template will now be available in Administrator  Extensions  Template Manager

  • Make the new template the default template.
  • View the site to verify it.

Finding Errors

You might have problems as a result of copying an existing template to a new template. Because of the way that Joomla handles file names, you might be tripped up by a capitalization error, for example.

Joomla contains some useful debugging tools. To see what is happening while working on a site, there are three settings that you should change.

  1. Administration > Site > Global Configuration > System > Debug Settings > Debug System > Yes (Default = No)
  2. Administration > Site > Global Configuration > System > Debug Settings > Debug Language > Yes (Default = No)
  3. Administration > Site > Global Configuration > Server > Server Settings > Error Reporting > Maximum (Default = System Default)

With the Debug Language set to Yes, for instance, you will see the success or failure of language file loading on each page of the Administrator. Open the Joomla Debug Console > Language Files Loaded panel to view the report.
