Re: [Mediawiki-l] About New version

I don't think it's a bug. "If" merely takes advantage of the fact that "multiple assignments of values to the same parameter in the same template call are allowed and result in the last value being used." [From http://meta.wikimedia.org/wiki/Help:Template_names%2C_variable_names_and_par ameters_depending_on_a_variable_or_parameter#A_parameter_name_depending_on_a _parameter] "If" works by passing to another template a parameter name as well as a parameter value based on the value of a parameter passed to it. [If this makes your head hurt, join the club! <grin>] Here's a step-by-step: "If" takes three parameters: the "test" value {{{1}}}, the "do-if-test-not-empty" value {{{2}}}, and the "do-if-test-is-empty" value {{{3}}}. "If" contains a call to "if2". The call's first parameter assignment sets an unnamed parameter to the "do-if-test-not-empty" value. The parameter is automatically given the name "1". Then there is a second parameter assignment. The name of the parameter in this assignment is "1" plus the test value. If the test value is empty, the name of the parameter is just "1", and this assignment overrides the first assignment, setting parameter "1" to the "do-if-test-is-empty" value. If the test value is not empty, the parameter name in the second assignment is "1xxxxxxx" or whatever, and no override takes place. "If2" just takes the value of the parameter named "1" passed to it and echoes it. If2 ignores all other parameters. The following equivalent code may be a little clearer: {{if2|1={{{2}}}|1{{{1}}}={{{3}}}}} HTH, -- Joshua On 10/12/05 2:05 PM, "Rob Church" &lt;robchur(a)gmail.com&gt; wrote:
