Gravity Forms Phone Validation WordPress

Hi People,

I am looking for phone validation using the gravity forms plugin, minium 8 numbers for the field and no "text = abc" allowed, I know we can't validate every phone number :)

The ID of the phone field is "3"

Hope someone can help!

Jayaram Y answers:

can you try this in functions.php



add_filter( 'gform_field_validation_175_1', 'custom_validation', 10, 4 );
function custom_validation( $result, $value, $form, $field ) {

if ( $result['is_valid'] && intval( $value ) < 8 ) {
$result['is_valid'] = false;
$result['message'] = 'Please enter a value more than 8';
}
return $result;
}

That doesn't work Jayaram! BUT does it have something to do with NOT assigning the ID of the field??

Thanks

Try this

add_filter( 'gform_field_validation_##_8', 'custom_validation', 10, 4 ); //Replace the ## with your form ID
function custom_validation( $result, $value, $form, $field ) {

$value = str_replace(array('(',')','-',' '),'',$value);//Remove hyphens, parenthesis, and spaces - you can take this out if you want strict numbers only

if ( $result['is_valid'] && strlen( $value ) < 8 && is_numeric( $value ) ) {

$result['is_valid'] = false;
$result['message'] = 'You have entered an invalid phone number';

}

return $result;

}

Kyle comments:

Carl,

Can you see my reply above and print out the $value field. Then please copy and paste the code as you have it in your functions.php file.


Carl Brook comments:

I put in exactly what you put above!

add_filter( 'gform_field_validation_##_8', 'custom_validation', 10, 4 ); //Replace the ## with your form ID

function custom_validation( $result, $value, $form, $field ) {



$value = str_replace(array('(',')','-',' '),'',$value);//Remove hyphens, parenthesis, and spaces - you can take this out if you want strict numbers only



if ( $result['is_valid'] && strlen( $value ) < 8 && is_numeric( $value ) ) {



$result['is_valid'] = false;

$result['message'] = 'You have entered an invalid phone number';



}



return $result;



}


Kyle comments:

Carl,

Did you see the note on the first line? You need to add your form ID in place of the ##

Also, please add

echo $value;
