الگو:Str sub find/doc

The Template:str_sub_find searches for a substring in a string at the given offset.

Usage

{{str sub find|<string1>|<string2>|<offset>}}

It returns 1, if string2 is found in string1 at the given offset, otherwise it will return empty string. This makes the result easy usable in Help:Extension:ParserFunctions like {{#if:|}}.
Offset is zero-based and can be omitted if zero.

Examples

• {{#if: {{str sub find|abcdef|abc}} | Substring is found | Substring is not found }} → Substring is not found
• {{#if: {{str sub find|abcdef|abc|2}} | Substring is found | Substring is not found }} → Substring is not found
• {{#if: {{str sub find|abcdef|def}} | Substring is found | Substring is not found }} → Substring is not found
• {{#if: {{str sub find|abcdef|def|3}} | Substring is found | Substring is not found }} → Substring is not found
