how to have a State validation rule for contact form?

See “other notes” for examples of custom validation filters. The one for limiting email domains would be a good starting point.

sorry i am not very good at coding but

what is this line for?

$domain = array_pop(explode(‘@’, $val));

and i would like that if the country user type in australia then this validation will come out…

I think I am doing it really wrong because when i tried on my website it goes true.. the validation doesnt work..

add_filter('sfwp2l_validate_field','block_country_abbr', 10, 4);

function block_country_abbr( $error, $name, /*$val, $field,*/ $country ){

    if( $name == 'State' & $country == 'Australia' ){

        $non_abbr = array( 'act', 'nsw', 'qld', 'sa', 'tas', 'vic,', 'wa', 'nt', 'NT', 'QLD', 'NSW', 'SA', 'ACT', 'TAS', 'VIC', 'WA' );

        //$domain = array_pop(explode('@', $val));

        if( in_array( /*$domain,*/ $non_abbr ) ){
            $error['valid'] = false;
            $error['message'] = 'Please enter Australian State in Full.';
        }

    }

    return $error;
}

I think i should put in the array the states spelt out in full instead?

I test it by putting states in abbr form and in full but it still goes through…. please help?

Yeah, that’s not going to work…

First off, you’d want a white list, not a black list.

You can’t arbitrarily pass variables to a filter ??

Try this:

add_filter('sfwp2l_validate_field','block_state_abbr', 10, 4);

function block_state_abbr( $error, $name, $val, $field, ){

    if( strtolower( $name ) == 'state' && $_POST['country'] == 'Australia' ){

       $val = trim( ucwords( strtolower( $val ) ) );

        $states = array( 'New South Wales', 'Queensland', 'South Australia', 'Tasmania', 'Victoria', 'Western Australia' );

        if( ! in_array( $val, $states) ){
            $error['valid'] = false;
            $error['message'] = 'Please enter Australian State in Full.';
        }

    }

    return $error;
}

you are a lifesaver Nick! initially i had another problem which is when people put the contry as australia instead of Australia .. the validation rule doesnt apply. but now i just put the countries in a drop down and it works! ‘

though i still cant figure out how to make the country text insensitive of lower or upper case ….

any hint?

anyway thanks!

strtower lower cases a string and allows you to make a case insensitive comparison. It’s already there in the code for field name.
