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)
 * 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 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)
