ViewFish Templating
Functions
You can also manipulate the variable using piped functions, e.g. {{variable|function}}. Note that functions can be chained, meaning {{variable|function1|function2|function3}} is valid syntax.
The functions that are current supported by default are:
- trim
- ucfirst
- ucwords
- nl2br
- strtoupper
- strtolower
- htmlspecialchars
- number_format
- stripslashes
- strip_tags
- md5
- intval
The following short-hand functions are supported:
- upper — wrap output in strtoupper
- lower — wrap output in strtolower
- escape — escape output
- e — an alias of escape
- sup — wrap output in sup tags
- sub — wrap output in sub tags
Multi-argument functions
ViewFish templates support multi-argument functions in the format {{var|function:arg1:arg2:arg3}}. Currently, you can use the following functions:
- substr:offset:length, e.g.
{{str|substr:3:10}}
Special functions
You can also use the shortcut function ellipsis to trim a string if it exceeds the argument. For example, {{var|ellipsis:18}} will trim and append "..." to a $var only if it exceeds 18 characters in length, including spaces.
{{date|format}} is supported, where format is an unquoted string using the arguments at php.net/date.
