They are 2 different types of template. ArticleHolder.ss maps to a class ArticleHolder but the search template maps to a function on Page - function action() on a ArticleHolder().

So if you have a function date() on your ArticleHolder class, and a url like site.com/articles/date then it'll use ArticleHolder_date.ss.

See the template documentation for more information.

CSS Files
By standard SilverStripe uses 3 CSS Files for your site -
• layout.css contains the layout and design of the site
• typography.css contains the styling for the text/fonts/links (used in both front and back ends)
• form.css styling for forms. Overriding
The templating system will search for the appropriate files in the following order:
1. mysite (or other name given to site folder)
2. themes
3. module (eg blog)
Subthemes
If you have a theme called mytheme_forum, it is considered to be a 'subtheme' of the mytheme theme. This lets module developers release extensions to popular themes that will let their module work with that theme.
A subtheme overrides the files in the module. So for instance, if you have the forum setup instead of editing the files within the forum/ module you would create a themes/yourtheme_forum/ folder.

ThemeDir
$ThemeDir
$ThemeDir(forum)

If you want to refer to an image or other file asset in a .ss template, use $ThemeDir. For example:
<img src="$ThemeDir/images/log.gif" />



If your image is in a subtheme, you can refer to that with an argument to ThemeDir. For example, if your image was in mytheme_forum, you could use the following code:
<img src="$ThemeDir(forum)/images/log.gif" />


Including Javascript & CSS
http://doc.silverstripe.org/sapphire/en/reference/requirements
Including inside PHP Code
Requirements::javascript("cms/javascript/LeftAndMain.js");
Requirements::css("cms/css/TreeSelector.css");

Including inside Template files
<% require css(cms/css/TreeSelector.css) %>
<% require themedCSS(TreeSelector) %>
<% require javascript(cms/javascript/LeftAndMain.js) %>
Note that currently (as of 2.3) you cannot pass a second parameter to a function via the template parser so doing the following will not work.
<% require css(cms/css/TreeSelector.css, 'screen,projection') %>
Combining Files
You can concatenate several CSS or javascript files into a single dynamically generated file. This increases performance reducing HTTP requests. Note that for debugging purposes combined files is disabled in devmode.
1
2
3
4
5
6
7
8 // supports CSS + JS
Requirements::combine_files(
'foobar.js',
array(
'mysite/javascript/foo.js',
'mysite/javascript/bar.js',
)
);
By default it stores the generated file in the assets/ folder but you can configure this by setting
1
2 // relative from the base folder
Requirements::set_combined_files_folder('folder');
If SilverStripe doesn't have permissions on your server to write these files it will default back to including them individually .

Image
Introduction
Represents an image object, inheriting all base functionality from the file class with extra functionality including resizing.
Resizing Images in PHP
The following are methods defined on the GD class which you can call on Image Objects. Note to get the following to work you need to have GD2 support in your PHP installation and // manipulation functions
$image->resize(width,height); // Basic resize, just skews the image
$image->resizeRatio(width,height) // Resizes an image with max width and height
$image->paddedResize(width,height) // Adds padding after resizing to width or height.
$image->croppedResize(width,height) // Crops the image from the centre, to given values.
$image->resizeByHeight(height) // Maximum height the image resizes to, keeps proportion
$image->resizeByWidth(width) // Maximum width the image resizes to, keeps proportion
$image->greyscale(r,g,b) // alters image channels ===
// values
$image->getHeight() // Returns the height of the image.
$image->getWidth() // Returns the width of the image
$image->getOrientation() // Returns a class constant: ORIENTATION_SQUARE or ORIENTATION_PORTRAIT or ORIENTATION_LANDSCAPE



Resizing in Templates
You can call certain resize functions directly from the template, to use the inbuilt GD functions as the template parser supports these, for example SetWidth() or SetHeight().
For output of an image tag with the image automatically resized to 80px width, you can use:
$Image.SetWidth(80) // returns a image 80px wide, ratio kept the same
$Image.SetHeight(80) // returns a image 80px tall, ration kept the same
$Image.SetSize(80,80) // returns a 80x80px padded image
$Image.SetRatioSize(80,80) // **New in 2.4** returns an image scaled proportional, with its greatest diameter scaled to 80px
$Image.PaddedImage(80, 80) // Returns an 80x80 image. Unused space is padded white. No crop. No stretching
$Image.Width // returns width of image
$Image.Height // returns height of image
$Image.Orientation // returns Orientation
$Image.Filename // returns filename
$Image.URL // returns filename
$Height
$Width
$CroppedImage(600,400) (with DOM)
$CroppedImage(600,400).URL // URL !!!
