Code	Sandbox	Current
{{If empty/sandbox}}			Returns an empty string.
{{If empty/sandbox|one}}		one	Returns the first parameter that is defined and not empty.
{{If empty/sandbox|one|two}}	two	one
{{If empty/sandbox|one|two|three|four}}	two	one
{{If empty/sandbox|two}}	two	two	The first parameter is empty/undefined, so is passed over.
{{If empty/sandbox|two|three|four}}	two	two
{{If empty/sandbox|two|four}}	two	two
{{If empty/sandbox|||||||||nine}}		nine
{{If empty/sandbox||||||||||ten}}		ten	Empty string returned if maximum of nine parameters exceeded.
{{If empty/sandbox}}			The only parameter is empty or undefined, so returns an empty string.
{{If empty/sandbox}}			Returns an empty string.
{{If empty/sandbox|{{{1|}}}|{{{2|}}}|three}}		three
{{If empty/sandbox|{{{1}}}|{{{2}}}|three}}	{{{2}}}	{{{1}}}	No pipe-characters following the names of the first two parameters ("1" and "2"), so the first of these returned as text ("{{{1}}}").
{{If empty/sandbox|{{{logo|}}}|two}}	two	two
{{If empty/sandbox|{{{logo}}}|two}}	two	{{{logo}}}	No pipe-character following the parameter name "logo", so the text "{{{logo}}}" returned.
{{If empty/sandbox|2=x}}	x		Unnamed parameters must be defined sequentially.
{{If empty/sandbox|p=q}}			The template identifies the parameters it receives as parameters 1 to 9, not using names such as "p", etc.
{{If empty/sandbox|one|{{X1}}[[Category:X1]]}}		one	Parameters after the first non-empty parameter are not expanded, so this page does not transclude Template:X1 and is not in Category:X1.
