AddRule Rangelength

[Han]

Hi all,

I'm trying to add and rule to validate dynamic fields and have only
been able to get it to work for valType="required" or any other rule
that doesn't require parameters.

Does anyone have some sample code for validating with parameters?

Thanks,
Han

You should be able to pass a struct of parameters into the addRule
method as an argument. For example:

params = {minLength=5, maxLength=10};
addRule(propertyName="userName", valType="rangeLength", parameters=params);

Yeah, I tried that. For some reason I keep getting this error:

Element INSTANCE.TYPE is undefined in VARIABLES.

You'll need to provide more detail than that for anyone to be able to
help you. Please provide the full stack trace, and also a snippet of
code that shows how you are calling the method.

Here's my code....

imageCaption_183 is a dynamic field, I just removed the loop so it's a little bit easier to read.

I also have a try/catch around the whole block to trap system errors.


             <!--- this works great ---> 
             <cfset application.vt.AddRule(
                            objectType="content-image",
                            propertyName="imageCaption_183",
                            formName="imageCaption_183",
                            propertyDesc="Image Caption",
                            valType="required") />
            <!--- this throws an error --->
            <cfset var params = { minLength=5, maxLength=10 } />
            <cfset application.vt.AddRule( theObject=arguments,
                            objectType="content-image",
                            propertyName="imageCaption_183",
                            formName="imageCaption_183",
                            propertyDesc="Image Caption",
                            valType="rangeLength",
                            parameters=params ) />
                                   
            <!--- validate --->
            <cfset result = application.vt.validate( theObject=arguments, objectType="content-image" ) />
            <cfset status = result.getIsSuccess() />
            <cfif ! status>
                <cfset toReturn.status = status />
                <cfset toReturn.error = result.getFailureMessagesByField() />
            <cfelse>
                <!--- save image --->
                ...
            </cfif>
