I am unable to check if my $check array is empty or contains information passed via post from a checkbox group.

if ($_POST) {
if ($error_array = validate_form() ) {
show_form ($error_array);
}
else {
process_form( );
}
}
else {
show_form ( );
}

function show_form($errors = []) {
include ("survey_inc. php");
}

function test_input($data) {
$data = trim($data);
$data = stripslashes($data);
$data = htmlspecialchars($data);

return $data;
}

// valid name, valid email, not empty check box, and valid radio and not empty.
function validate_form() {
$errors = []; // start with empty array
$name = test_input($_POST['name']);
$email = test_input($_POST['email']);
$check = test_input($_POST['bucket']);
$radio = test_input($_POST['species']);

// checking to see if name is 2+ characters
if (strlen($name) < 2) {
$errors[] = "Name is too short or empty.";
}

// check email
if (! filter_var($email, FILTER_VALIDATE_EMAIL) ){
$errors[] = "Enter a valid email.";
}

// check check group
if (empty($check)) {
$errors[] = "Please select a Bucket list item, even if it's not on your list.";
}
/*if (!empty($check)) {
switch ($check) {
case "skydiving":
break;
case "rocky_mountain_climbing":
break;
case "bull_riding":
break;
default:
$errors[] = "Please select a bucket list item...from the list.";
}
}

an ironworker standing 30 feet in the air is safe wearing a full body harness that is not tied-off.

i would first let him be aware that a cover letter is official and confidential and it requires a proper formatting so that the employer doesn't have hard time when going through it. he should write it in paragraphs of about two to four sentences and use proper grammar a , spelling and proper punctuation. i will also advice him not to be emotional and not also to use images.then base his attention to the details of the job described and not other things. that is he be specific to the responsibilities and to the employers requirements. on this he should make sure that the letter reflects how good he is for the requirements detailed by the employer

the letter should not be too long nor too short.
