This parser function can be used to detect whether a template parameter is defined, even if it has been set to a false value. For example, to check whether the first positional parameter has been passed to a template (note that the strings " + " and " - " can be any two different non-whitespace strings):
If the template has a separate documentation page (usually called "Template:template name/doc"), add [[Category:Text-specific formatting and function templates]] to the <includeonly> section at the bottom of that page. Otherwise, add <noinclude>[[Category:Text-specific formatting and function templates]]</noinclude>
This helper template is designed to be used in other templates. It can help editors create template code that is more self documenting. A major advantage of using this template over using the construct {{#if:{{{1|}}}{{{2|}}} |…}} is that if the first parameter is not empty then the second parameter is not evaluated.
Each nested use adds 5 levels to the template expansion depth, so 7 nested if-templates would use 35 levels (5*7) of the 41-level limit. Using P-if syntax: A similar if-structure can be coded without Template:If, by using the {} and {} templates in a "P-if" structure. Template:P1 always returns parameter 1, and P2 returns the 2nd. So, a ...

If-then-else flow diagram A nested if–then–else flow diagram. In computer science, conditionals (that is, conditional statements, conditional expressions and conditional constructs) are programming language constructs that perform different computations or actions or return different values depending on the value of a Boolean expression, called a condition.
For evaluating the condition (determining non-emptiness of the first parameter) the template uses parser function #if, producing 1 if the condition is true, and 2 otherwise. The template with name equal to "P" followed by the index value produced (hence Template:P1 or Template:P2), is called with as parameters A and B. This produces either A or ...
This template is used on approximately 6,900 pages and changes may be widely noticed. Test changes in the template's /sandbox or /testcases subpages, or in your own user subpage . Consider discussing changes on the talk page before implementing them.
