The content after a {foreachelse} tag is included only if the {foreach} block would otherwise be empty. Modifiers Smarty provides modifiers that can be used to gain greater control over the formatting of data. Modifiers can be included by following a variable with a vertical bar | and the name of the modifier. Any arguments to the modifier can be specified using a colon : followed by the arguments. The following example prints a date using the YYYY-MM-DD syntax: {$expire_time|nwadateformat:"%Y-%m-%d"} See"Date/Time Format Syntax" on page 279 for detailed information on the date/time format modifiers, and see Table 26.

The result of a template function takes the place of the function in the output of the template. Functions are of two kinds: block functions, which have a beginning and ending tag enclosing the text operated on by the function, and template functions, which have just a single tag and do not enclose text. To use a function, enclose the function name in curly braces { } and provide any attributes that may be required for the function. Block functions also require a closing tag. dump {dump var=$value} 266 | Modifiers Dell Networking W-ClearPass Guest 6.0 | Deployment Guide
