TConditional

+ + +

+TConditional displays appropriate content based on the evaluation result +of a PHP expression specified via Condition. +If the result is true, it instantiates the template TrueTemplate; +otherwise, the template FalseTemplate is instantiated. +The PHP expression is evaluated right before the onInit stage of the control lifecycle. +

+ +

+Since TConditional evaluates Condition at a very early stage, it is recommended +you set Condition in template only and the expression should not refer to +objects that are available on or after the onInit lifecycle. +

+ +

+TConditional is very light. It instantiates either TrueTemplate +FalseTemplate, but never both. And the condition is evaluated only once. +A typical usage of TConditional is shown as following: +

+ + +<com:TConditional Condition="$this->User->IsGuest"> + <prop:TrueTemplate> + Login + </prop:TrueTemplate> + <prop:FalseTemplate> + Logout + </prop:FalseTemplate> +</com:TConditional> + + + + +
