isValid(..) quick question 1

[ice78991]

IsValid("string",arguments.str) will pass empty strings as valid. Is it possible to modify this so empty strings are not allowed

 

[cfSearching]

I imagine not, since an empty string is still a valid string. Why not just add a Len() check?

Why not also do:

isvalid("trim(string)",arguments.str)

the trim() will remove all whitespace.

great idea...thanks

 

[cfSearching]

isvalid("trim(string)",arguments.str)

That is not allowed. The first argument must be a valid type: "string". You must trim or check the length of the value itself.

You can also do this, if what cfSearching says is true:

<cfset one = trim(FORM.string)>

THEN do:
isvalid("one",arguments.str)

Hi Kevin, isvalid("trim(string)",arguments.str) was my suggestion. I did not know that the first argument must be a valid type: "string".

My second example, was again a suggestion...I thought this should work. You'd be trimming FORM.string, then running it through isvalid(). In the second suggestion, the first argument must be a valid type: "string".

the first argument must Literally! be one of:

'string'
'integer'
'url'
'email'
(there are plenty more..)

the second is the variable that you are checking.

<cfset badEmail = "kevin#domain.com">
<cfset goodEmail = "kevin@domain.com">

isValid("email",badEmail) = FALSE
isValid("email",goodEmail) = TRUE
