Hi,
i have a function that simply tries to match a value that is being passed in
matches a title. the function is currently as follows:
<cffunction name="isValidTitle" hint="is passed a value, and checks to ensure
that it is either M or F, and either returns true or the error">
<cfargument name="value" type="any" required="true">
<!--- declare the regaulr expression set --->
<cfset var titleRegEx = "\b(Dr|Prof|Mr|Mrs|Ms|Miss)\b"> <!--- allowable --->
<cfset var regExMatchArray = rematchnocase(titleRegEx,value)>
<!--- looks through the string to find m or f, if everything is ok then it
returns a number 1 greater than the length of the value, else it returns the
position of the character in the value that it fails on --->
<cfif arraylen(regExMatchArray) eq 0 or len(regExMatchArray[1]) neq
len(value)>
<cfreturn "Invalid Title: #value# (Valid Title: Dr,Prof,Mr,Mrs,Ms,Miss)">
<cfelse>
<cfreturn true>
</cfif>
</cffunction>
i have been looking at various regex tutorials about options, and also looked
the the very useful regex tutorial site:
http://www.regular-expressions.info/alternation.html
but the problem i am having is that it will match any pattern including the
pipe, so if i type in Dr| then it will return true. however i want it to return
false, i cannot seem to find anywhere that tells me how to deal with this
i would appreciate any feedback
thanks
richard
