GravityForms Dynamic Confirmation Redirects - url

Question

I have set up a gravity form with a single line text field. I am using it to check for zip codes and cities. If someone types in the correct zip code it will redirect to a specific page. Also if someone types in a zip code or city and there is no matching value it will also redirect to a certain page. I have tried this code. But I can not seem to get it to work correctly. It works if I have one number but if I add multiple numbers separated by a comma it does not work. Please help if possible.
<?php
function de_gforms_confirmation_dynamic_redirect( $confirmation, $form, $entry, $ajax ) {
if ( $form['id'] == '38' ) {
if ( $entry['1'] == '89103,80205,91030' ) {
$confirmation = array( 'redirect' => 'https://google.com' );
} else if ( $entry['1'] == '90210,89554,90454' ) {
$confirmation = array( 'redirect' => 'https://yahoo.com' );
} else if ( $entry['1'] == '56678,89004,78896' ) {
$confirmation = array( 'redirect' => 'https://test.com' );
}
}
return $confirmation;
}
add_filter( 'gform_confirmation', 'de_gforms_confirmation_dynamic_redirect', 10, 4 );
?>

Answer 1

You need to use the or operator "||" instead of the array of zipcodes
<?php
function de_gforms_confirmation_dynamic_redirect( $confirmation, $form, $entry, $ajax ) {
if ( $form['id'] == '38' ) {
if ( $entry['1'] == '89103' || $entry['1'] == '80205' || $entry['1'] == '91030' ) {
$confirmation = array( 'redirect' => 'https://google.com' );
} else if ( $entry['1'] == '90210' || $entry['1'] == '89554' || $entry['1'] == '90454' ) {
$confirmation = array( 'redirect' => 'https://yahoo.com' );
} else if ( $entry['1'] == '56678' || $entry['1'] == '89004' || $entry['1'] == '78896' ) {
$confirmation = array( 'redirect' => 'https://test.com' );
}
}
return $confirmation;
}

There's a lot of ways you could do this. I would probably try to turn your zip codes/redirect into an associative array (https://wtools.io/convert-csv-to-php-array) that you could loop through like this:
function de_gforms_confirmation_dynamic_redirect( $confirmation, $form, $entry, $ajax ) {
$zip_group = array("1234","2345","3456");
$count_group = count($zip_group);
for($i=0;$i<$count_group;$i++){
$redirect[$i]='https://google.com';
}
$zip_condition = array_combine( $zip_group , $redirect );
if( $form['id'] == '38' ) {
foreach($zip_condition as $zip => $condition) {
if ( $entry['1'] == $zip ) {
$confirmation = array( 'redirect' => $condition );
}
}
}
return $confirmation;
}
