Validate two fields... - checog0 - Sep 18th, 2009

Hi, I want to know if its possible to validate two fields,

I have a field "city" type select and field "section" type text,

Now, each city (I have about 100) have about 8 sections, but I don't wanna show the sections for each city, I want validate the sections depends of the city selected, if the section typed doesn't correspond to city sections show and error in the section filed.

its possible?

Hi Checog,

Sure, no problem! For the PHP validation, that's no problem - you can just test for the city value, then run the appropriate validation rules. For JS, you need to use the following rule format:

Code:
rules.push("if:city=Vancouver,required,field1,Please enter field 1.");
rules.push("if:city=Seattle,required,field2,Please enter field 2.");

In that example, field1 will only be validated (checked it's been filled in) if and only if the user has selected Vancouver in the city field.

Hope this helps!

For example, how to validate:

If I have a field City and field regcode, city field its type select and regcode its text type, user have to enter this value manually

In regcode field, If city=Vancouver and regcode= 1125 or 1518 or 2115 or 3425 its valid, any other value its incorrect

Each city have about four or nine valid regcodes, I want to validate that each user insert a valid code for the city that has been select.

finally it works, I did use:

rules.push("if:city[]=Vancouver,reg_exp,regcode,^\s*(1125|1126|1127)\s*$, wrong regcode city");
