ifne (IF Not Empty)

• General template to return the first non-empty (numbered) parameter'.
• Generally intended for use with more than 2 parameters.
• Current max:5 (See: notes)
• Returns empty string if all inputs are empty. (See: Optional)

General use.

{{ifne|<parm1>|<parm2>|...}}

Example: {{ifne| {{{p1}}} | {{{p2}}} |{{{p3}}} }}

Note that if there is a change the used parameters might not be SET. Do use the additional "|" after the parameter name.

Like: {{ifne| {{{p1|}}} | {{{p2|}}} |{{{p3|}}} }}

This is the general fail-save way to use it.

Optional.

• "EE=" flag which will trigger error on empty-string return.

{{ifne|EE=|<parm1>|...}} -- Position of "EE=" don't matters.

Additional notes.

• All leading and trailing spaces around parameter content are always ditched by used MW-process.
• Max exceeded error: Only return this error if fist data is found after parm-5. Checks up to parm-9.
• ...

Background.

When using {{{p1| {{{p2| {{{p3|}}} }}} }}} it will check if p1 and p2 are NOT SET. But this will not work with SET but still EMPTY parameters.

Only {{#if:<if not set OR empty>{{{p1|}}}|<than>{{{p1}}}|<else>...}} will do empty parameter checking.

This template will take care of that, removing the need to have the related bulk-code inside other templates.
