Description

Return a validated name field

At the start of coding this all we wanted to do was to not accept a name starting with a digit e.g. 532ff6123 Because, except for names in non Latin languages, it should really be a letter. So I looked at stack overflow and found this, which seems like as good a start as any http://stackoverflow.com/questions/888838/regular-expression-for-validating-names-and-surnames Trying this Regular expression ^[\p{L} \.'\-]+$ But in the 'complete tested solution' it's ^[\p{L}\p{M}' \.\-]+$ And perhaps we need to convert apostrophes to ' Apostrophes are dealt with by stripping slashes from the input value before performing the preg_match. Later, if the field is redisplayed, then we run stripslashes again.

Usage

$string|null = oiksp_validate_name();

Parameters

Returns

string|null the name field if validated
