Every theme comes with the file theme.php. However, for most themes, the file is nearly empty. The reason for that is that only things that differ from Coppermine's default behaviour needs to be described in theme.php. Things that are suppossed to work "the usual Coppermine way" are being defined in the core code - your custom theme's theme.php contains the variables and function definitions that override the identical items in the default core.
The "theme.php" file contains all the HTML templates used by the script. You can edit them, as well. When making modifications to these templates, be careful that you do not alter the lines that start with <!-- BEGIN xxx --> and <!-- END xxx -->. These lines are often used to identify the start and end of specific code blocks that the script will use to display your gallery.
Basically, there can be three types of content in theme.php (from a PHP-coder's point of view). Don't worry though - you don't have to be a coder to be capable to change your theme
Your Coppermine installation also includes a "sample" theme directory. The "sample" theme includes each of these files but does not show up in the user selectable list of themes in your Coppermine display. Sample's theme.php also holds a copy of every themeable function and template for your reference. If you opt to use the "sample" theme to begin creating your own theme, you should follow the theme.php instructions in the "theme upgrade documentation" and begin with a blank theme.php.
This being said: you mustn't start your custom theme by copying the sample theme - start with a vanilla theme.php instead. Only use themes/sample/theme.php to copy individual sections that you want to modify into your custom theme and then modify it.
Newbies often have issues to understand what a "section" is that they need to copy from the sample theme - if you don't know much about PHP, it's sometimes hard to understand where a function definition starts and where it ends. That's why we have "wrapped" the individual sections that contain more than one line into comment blocks that try to catch your attention: a section starts with the block
/****************************************************************************** ** Section <<<section_name>>> - START ******************************************************************************/and ends with
/****************************************************************************** ** Section <<<section_name>>> - END ******************************************************************************/where the name of the section (section_name in above example) is identical both in the start-block as well as the end-block.
The place where you insert the section you copied from the sample theme in your custom theme doesn't matter as long as you take care not to paste it within another section, but before or after a section that exists in your custom theme. As a rule of thumb, you can savely paste a section into a new line before ?> in your custom theme (themes/yourtheme/theme.php)
The method behind all theme.php editing is really quite easy - just follow these simple steps:
So, what can actually be accomplished by editing theme.php? Well, the sky is the limit: only your imagination can be limited, but the scope of possible edits in theme.php is endless. However, users usually ask for the same five or six features or changes all the time. That's why we have created a page with theme examples where the most common edits to theme.php are being explained - make sure to have read those examples thoroughly before starting another request on the coppermine support board where you might just be told that you should read the docs...
| Item | Type | Description | Dependancies |
|---|---|---|---|
| define('THEME_HAS_PROGRESS_GRAPHICS',1); |
constant | Coppermine displays a "loading"-icon when the upload form is being submit to indicate that there must be no user interaction while the script is busy uplading. When this constant is set, the script will fetch the "loading"-icon from the theme's images folder (themes/yourtheme/images/loader.gif). If the constant is not set, the default loader image will be used, taken from the generic images folder. When designing a theme of your own, make sure that the loader image actually exists when setting this constant. | If defined, a file named loader.gif needs to reside in the theme's images folder. |
| define('THEME_HAS_RATING_GRAPHICS',1); |
constant | The location for the ratings graphics. When the constant is set, the script will be directed to the theme's images folder, i.e. themes/yourtheme/images/ and look for the rating images there. If not defined (default), the rating images will be taken from the images-folder that resides in Coppermine's root folder. | Graphic resources in themes → Rating images |
| define('THEME_HAS_MENU_ICONS',16); |
constant | The location for the menu icon graphics that are being displayed if the config option "Enable menu icons" has been turned on. When the constant is set, the script will be directed to the theme's images folder, subfolder 'icons', i.e. themes/yourtheme/images/icons/ and look for the menu icon images there. If not defined (default), the menu icon images will be taken from images/icons/. Unlike most other custom theme constants, the value you assign to the constant does matter in this case: set it to the size (in pixels) that your custom icons have. The custom icons (as well as the default icons) need to be square in shape. If you decide to use your own set of menu icons for your custom theme, it's advisable to copy the folder images/icons/ into themes/yourtheme/images/ to have a set of defaults and then start modifying your custom menu items one by one. |
|
| define('THEME_HAS_NAVBAR_GRAPHICS',1); |
constant | The location for the navbar graphics ("ecard", "slideshow", "previous"/"next"). When the constant is set, the script will be directed to the theme's images folder, i.e. themes/yourtheme/images/ and look for the navbar images there. If not defined (default), the navbar images will be taken from the images-folder that resides in Coppermine's root folder. | Graphic resources in themes → Image Navigation bar |
| define('THEME_HAS_FILM_STRIP_GRAPHIC',1); |
constant | The location for the film strip graphics. When the constant is set, the script will be directed to the theme's images folder, i.e. themes/yourtheme/images/ and look for the film strip images (tile.gif) there. If not defined (default), the film strip images will be taken from the images-folder that resides in Coppermine's root folder. | If defined, a file named tile.gif needs to reside in the theme's images folder. [Details] |
| define('THEME_HAS_NO_SYS_MENU_BUTTONS',1); |
constant | When present the system won't attempt to replace {BUTTONS} in the SYS_MENU template | |
