I’m using the Address field in my forms so there is no way of setting a mask for the individual sub fields in the Address field. I need to validate the zip code field such that, upon submission, if the field contains anything other than 5 numerals, the form should show an error message just like any…

I got it. You were right about gform_field_validation_3_55; then I referenced the subfield .5 below and it worked: $zip_value = rgar( $value, $field->id . ‘.5’ ); Thanks!

I spoke too soon. The code now throws the error, but replacing the zip with a 5-digit string still continues to throw the same validation error.

Well, that’s one step closer to the solution either way :wink: In the code you pasted above, the ‘demo zips’ are still mentioned (which are both 3 numbers). Is that the code you’re indeed using? Because that situation doesn’t resemble what you’re trying to achieve. You could use ctype_digit + strl…

[image] hiranthi: if ( ! ctype_digit( $zip_value ) || 5 != strlen( $zip_value ) ) { $result[‘is_valid’] = false; $result[‘message’] = ‘Zip validation failed.’; } So like this: add_filter( ‘gform_field_validation_3_55’, ‘custom_zip_validation’, 10, 4 ); function custom_zip_validation( $resu…

That worked, but what if I want to use the same filter for more than one form on my site? I repeated the filter and updated the form but with both filters in my functions.php, the site was not accessible. What would the syntax look like for two forms / 2 field IDs?

So would the syntax look like this if the two forms are ID 6 and ID 7 with both having the zip field at 15.5? add_filter( ‘gform_field_validation_6_15’, ‘gform_field_validation_7_15’, ‘custom_zip_validation’, 10, 4 ); function custom_zip_validation( $result, $value, $form, $field ) { if ( $resul…

I tried the above and it doesn’t work. So I’m not sure how to have the same filter run on multiple forms.

The add_filter should be used once per form. The first string is the filtername, the second string is the name of the function that should be used. In yours the first two strings are filter names and the third is the functionname. Since the second string is recognized by WordPress as the function an…

Then you’d add a seperate add_filter for that form + field ID (and I’d select it at field type address inside the function instead of the field ID to keep it compact & more scalable).
