The /default folder contains all the theme, css and image files, while /default_02 and /default_dark are variations of the default theme and contain only "modified" files and images. Files that don't exist in those folders are used from the /default theme folder.

This is because the /default theme should always be intact to make JReviews upgrades easier.

You will notice that &quot;dark&quot; and &quot;mobile&quot; theme folders contain less files than the &quot;default&quot; theme folder. The default theme is a &quot;fallback&quot; theme which contains all the necessary files, while dark and mobile themes are variations of the default theme and contain only &quot;modified&quot; files and images. If a theme doesn't contain a certain file, JReviews will load that file from the default theme. That makes updating themes easier.
If you want to modify theme files, you can create your own theme or copy the files you want to modify into "jreviews_overrides" folder.

== Creating your own theme ==
+
 
+
#Read the [[Default theme overview]] to learn the file structure
+
#Create a new folder for your theme
+
#Copy the /theme_images folder with all its images from the default theme folder into your theme, because they are always read from the currently theme and not from the default one
+
#Copy the /theme_css/images folder also if you want to use the same images as the default theme
+
#Copy the files you want to modify into your theme folder (other files leave in the default theme folder)
+
#After your theme is done, to use it go to JReviews Configuration, tab 'General' and select it from the dropdown
+
#'''Important:''' For JReviews to recognize new files, you must click on 'Clear File Registry' link in JReviews Administration
+
 
+
 
+
== Modifying theme files ==
+
 
+
Creating your own theme is not necessary if you only want to modify several files from the default theme.
+
  
Instead, use the [[JReviews Code Overrides]] feature to create a copy of theme files you want to modify outside the '''/com_jreviews''' folder, and those files will be used instead of the ones in /themes/default folder.
+
If you want to make theme customizations, create a custom theme similar to the dark theme. Theme files in the default theme should never be modified.
  
For example, if you want to make modifications to the detail page theme file:
+
Instead of creating your custom theme in <span style="color: blue">/components/com_jreviews/jreviews/views/themes/</span> folder, you should use the [[JReviews Code Overrides]] functionality to place your custom theme outside the /com_jreviews folder. That way you won't lose your custom theme when you upgrade JReviews.
*<span style="color: blue">/themes/default/listings/detail.thtml</span>
+
  
 +
You will find 3 settings for theme selection in JReviews Configuration:
  
Create a copy of the file into this folder:
+
[[File:theme-settings.png]]
*<span style="color: blue">joomla_root/templates/jreviews_overrides/views/themes/default/listings/detail.thtml</span>
+
  
and then make the modifications.  
+
'''Site theme''' - this is the main theme that will be used for the JReviews frontend. If you will create a custom theme, this is where you'd select it.
  
 +
'''Mobile theme''' - here you can choose a theme that will be used on smartphones. It is recommended to select the same theme that you selected for '''Site theme'''. The ''Default Theme'' is responsive and works fine on mobile devices by default. The only reason why you might want to use a separate mobile theme is if you want to delete certain page elements only for smartphones. JReviews includes a ''Mobile Theme'' that you can use for this purpose.
  
Do the same for any other theme file.

'''Fallback theme''' - all theme files that the selected '''Site theme''' doesn't have will be loaded from the fallback theme. The ''Default Theme'' should always be selected here (unless JReviews will have two different fallback themes in the future).
  
After copying the files into /jreviews_overrides folder, you need to click on 'Clear File Registry' link in JReviews Administration.

JReviews uses a php templating system. This means you can mix html with php code, which provides a lot of flexibility to create conditionals and add snippets of php code.

JReviews Themes

JReviews themes are located in this folder:

  • /components/com_jreviews/jreviews/views/themes/

You will find several themes there:

  • /components/com_jreviews/jreviews/views/themes/default/
  • /components/com_jreviews/jreviews/views/themes/dark/ - for using with dark Joomla templates
  • /components/com_jreviews/jreviews/views/themes/mobile/ - for mobile devices

You will notice that "dark" and "mobile" theme folders contain less files than the "default" theme folder. The default theme is a "fallback" theme which contains all the necessary files, while dark and mobile themes are variations of the default theme and contain only "modified" files and images. If a theme doesn't contain a certain file, JReviews will load that file from the default theme. That makes updating themes easier.

If you want to make theme customizations, create a custom theme similar to the dark theme. Theme files in the default theme should never be modified.

Instead of creating your custom theme in /components/com_jreviews/jreviews/views/themes/ folder, you should use the JReviews Code Overrides functionality to place your custom theme outside the /com_jreviews folder. That way you won't lose your custom theme when you upgrade JReviews.

You will find 3 settings for theme selection in JReviews Configuration:

Theme-settings.png

Site theme - this is the main theme that will be used for the JReviews frontend. If you will create a custom theme, this is where you'd select it.

Mobile theme - here you can choose a theme that will be used on smartphones. It is recommended to select the same theme that you selected for Site theme. The Default Theme is responsive and works fine on mobile devices by default. The only reason why you might want to use a separate mobile theme is if you want to delete certain page elements only for smartphones. JReviews includes a Mobile Theme that you can use for this purpose.

Fallback theme - all theme files that the selected Site theme doesn't have will be loaded from the fallback theme. The Default Theme should always be selected here (unless JReviews will have two different fallback themes in the future).
