=== Important considerations === | |||
Some important considerations when creating templates: | |||
* Line breaks interact unexpectedly with the table parser, which can break some templates. | |||
* Adding a pipe to a template parameter <nowiki>{{{parameter}}} > {{{parameter|}}} </nowiki> will provide it with a default value (in this case, an empty string). | |||
** This is important to remember when using the <nowiki>{{#if:}} </nowiki> parser function, since in cases where a parameter is undefined, <nowiki>{{{parameter}}}</nowiki> will return the value "true", whereas <nowiki>{{{parameter|}}}</nowiki> will return the value "false". | |||
** It is alao important to remember when a parameter is used as a value, since in cases where a parameter is undefined, <nowiki>{{{parameter}}}</nowiki> will return the value "<nowiki>{{{parameter}}}</nowiki>", whereas <nowiki>{{{parameter|}}}</nowiki> will return its default value (in this case, an empty space). | |||
* Expr and ifeq, when evaluating numbers, produce different results. This is because expr treats numbers as floats, whereas ifeq treats them as integers. | |||
