param

For use in templates: Returns the first parameter found from a list of parameter names, or the last argument if none were found. Intended to be easier to read than a chain of template default arguments. The following lines are equivalent:

{{{first|{{{2|{{{1|{{{last|None of the parameters were found}}}}}}}}}}}}
{{#param:first|2|1|last|None of the parameters were found}}

Example:

"Template:Sample" contains:

{{#param:first|2|1|last|None of the parameters were found}}

---

{{sample|first=text}}

→ text

---

{{sample|text}}

→ text

---

{{sample|foo|bar}}

→ bar

---

{{sample|a|b|last=c|first=First!}}

→ First!

---

{{sample|3=foo}}

→ None of the parameters were found
