ਫਰਮਾ:CheckElement
Template that returns an error message if the first argument is not valid for use with other nuclide templates helper templates.
Usage
ਸੋਧੋWhen using a string that is not a valid element name or symbol or "x" or "element", an error message is returned, like so:
{{CheckElement|C}}will return ""{{CheckElement|Carbon}}will return ""{{CheckElement|Blablabla}}will return "The element Blablabla does not exist."
The "link=yes" argument is also supported; if the element name or symbol has no associated link, an error message is returned, like so:
{{CheckElement|link=yes|C}}will return ""{{CheckElement|link=yes|Carbon}}will return ""{{CheckElement|link=yes|X}}will return "The generic element 'X' does not have a page to link to."
When using a common name for an element that goes against the Wikipedia style guide for element names, a warning message will be returned. There are currently three such names:
{{CheckElement|Aluminum}}will return "Aluminum is not a valid way to spell aluminium."{{CheckElement|Sulphur}}will return "Sulphur is not a valid way to spell sulfur."{{CheckElement|Cesium}}will return "Cesium is not a valid way to spell caesium."
This template can be used in other templates to check for error before calling other templates that require a valid element or symbol like so:
{{#if:{{CheckElement|{{{element argument}}}|link={{{link|}}} }}
| Error message (shown when the element is invalid).
| Normal message (shown when the element is valid).
