Thank you for your fast response! I inserted the code you listed, but it’s not working at the moment. Forgive me if i’m missing something obvious. My form is blocking duplicate teams as it was before, however it still is not blocking submissions from users that have already submitted. See my code below. Thanks a million!
`/**
* @param $formName string
* @param $fieldName string
* @param $fieldValue string
* @return bool
*/
function is_already_submitted($formName, $fieldName, $fieldValue) {
require_once(ABSPATH . ‘wp-content/plugins/contact-form-7-to-database-extension/CFDBFormIterator.php’);
$exp = new CFDBFormIterator();
$atts = array();
$atts[‘show’] = $fieldName;
$atts[‘filter’] = “$fieldName=$fieldValue”;
$atts[‘unbuffered’] = ‘true’;
$exp->export($formName, $atts);
$found = false;
while ($row = $exp->nextRow()) {
$found = true;
}
return $found;
}
/**

* @param $tag array

function my_validate_email($result, $tag) {
$formName = ‘Team_Form’; // Change to name of the form containing this field
$fieldName = ‘Team’; // Change to your form’s unique field name
$errorMessage = ‘Email has already been submitted’; // Change to your error message
$name = $tag[‘name’];
if ($name == $fieldName) {
if (is_already_submitted($formName, $fieldName, $_POST[$name])) {
$result->invalidate($tag, $errorMessage);
}
}
return $result;
$fieldName = ‘Submitted Login’;
$current_user = wp_get_current_user();
if ( 0 == $current_user->ID ) {
// Not logged in.
$result->invalidate($tag, ‘Not logged in’);
} else {
// Logged in.
$fieldValue = $current_user->user_login ;

$result->invalidate($tag, $errorMessage);
}
}
