Help talk:Switch parser function

Question

Is there a way to just switch out certain characters in the string? For example, I want to change all hyphens to spaces. How can I do this?  Nixinova  T  C  06:02, 15 May 2018 (UTC)

@Nixinova: This "switch" parser function won't help you with that, but take a look at Template:Replace -- John of Reading (talk) 06:47, 15 May 2018 (UTC)

Default and missing Switch variable

In my experience, see: https://nl.wikibooks.org/wiki/Sjabloon:Kolommen2_(variabel), versions dated april 18, 2020, the default value is NOT echoed when the selector is missing from the list of parameters passed to the template.

The situation occurred when a few related templates were combined into the template mentioned above. To let the template function as before (without the selector parameter Var1), the default option was intended, but did not work correctly. The problem was solved by placing the switch in the TRUE branche of an IF THEN ELSE instruction and the original action in the FALSE branche.

{{Testing

{{ #switch: {{{Var1|}}}

| 1 = one

| 2 = two

| other

}}

Calling above template by

AA{{Testing}}BB

Without any parameter resulted in

AABB

Only when the template was altered into

{{Testing	Start template
{{ #if: {{{Var1|}}}	Start If function
| {{ #switch: {{{Var1|}}}	Start switch
| 1 = one	First option
| 2 = two	Second option
}}	End of switch function
| other	ELSE part of the if function
}}	End of if function
}}	End of template

the call now resulted in

AAotherBB

It took some time to figure out what was happening.T.vanschaik (talk) 20:58, 18 April 2020 (UTC)
