Hi, a couple of things. First of all if you are checking if form fields
have a value - either trim all your form fields before your validation
or trim then when testing e.g.
<cfif trim(form.PropertyDataVillageTown) is "">
or even <cfif len(trim(form.PropertyDataVillageTown)) eq 0 >
Second thing is as in essence you're building up a list so you could do
this for each validation clause to make your code a bit more readable
<cfif trim(form.PropertyDataVillageTown) is "">
<cfset MessageAlert = listAppend(MessageAlert, "<font
color='b23f3f'><b>Village/Town</b></font> must have a value." , "<br")
>
</cfif>
Using "<br>" as the delimiter .
Also you may want to wrap the field names in a style sheet class
<span class='fieldHighlight''> Village/Town</span> which would mean you
wont have to change your code (only your stylesheet) when the designer
decides to use #b23f3f as the background colour ;-)
Then you need only check the length of the list once at the end to see
if an error occurred
<cfif listLen(MessageAlert) >
<cfset ErrorFound = "yes" >
</cfif>
Finally you would have to add additional validation before reaching the
SQL statement if you want to ensure a field has a minimum length, this
can be done on the database but I wouldn't do it that way!
Hope that helps
Kola

Subject: cfqueryparam, cfcatch 'n cftry
Hi guys,
In my cfcatch i've got a bunch of <cfif>'s checking to make sure all
parts of my form were correct.
e.g.:
<cfif form.PropertyDataVillageTown is ""><cfset MessageAlert =
MessageAlert & "<font color='b23f3f'><b>Village/Town</b></font> must
have a value.<br>"><cfset ErrorFound = "yes"></cfif>
<cfif form.PropertyDataCountyState is ""><cfset MessageAlert =
MessageAlert & "<font color='b23f3f'><b>County/State</b></font> must
have a value.<br>"><cfset ErrorFound = "yes"></cfif>
<cfif form.PropertyDataPostcodeZip is ""><cfset MessageAlert =
MessageAlert & "<font color='b23f3f'><b>Postcode/Zip</b></font> must
have a value.<br>"><cfset ErrorFound = "yes"></cfif>
However, all these actions will only take place if there is an error
triggered.
I have one field which is a description and i'd like to trigger an error
if it is less than 10 characters in length and more than 120. When i am
using cfqueryparam in my SQL i noticed i can have such a line:
<cfqueryparam cfsqltype="cf_sql_longvarchar" maxlength="120">
Will this the right thing to trigger an error in case it's more than 120
characters?? How about if i want to trigger the error if it's less than
10 characters too, can that not be done.
BTW: i just chucked in that cf_sql_longvarchar because i didn't know
what to use.
Thanks,
Stu
