\n
You have the following in your code:<\/p>\n
$name = $_POST['$name'];\n$email = $_POST['$email'];\n$dob = $_POST['$dob'];\n<\/code><\/pre>\nYou’re basically trying to access undefined indexes. Remove the extra $<\/code> from the key names:<\/p>\n$name = $_POST['name'];\n$email = $_POST['email'];\n$dob = $_POST['dob'];\n<\/code><\/pre>\nThen, further below, you have some conditions like this:<\/p>\n
if(condition == true) {\n continue;\n} else {\n \/\/ do something\n}\n<\/code><\/pre>\nIt’s actually not necessary, and you could change it to:<\/p>\n
if(!condition) {\n \/\/ do something\n}\n<\/code><\/pre>\nAlso, it’s better to push the error messages into an array ($errors<\/code>) and then loop through it and display the error messages. It might help organize your code a bit better.<\/p>\nHere’s how the modified code looks like:<\/p>\n
if(!empty($_POST)) {\n $name = $_POST['name'];\n $email = $_POST['email'];\n $dob = $_POST['dob'];\n\n $namelen = strlen($name);\n $emaillen = strlen($email);\n $max = 255;\n $minname = 2;\n $minemail = 3;\n\n if($namelen < $minname){\n $errors[] = \"name must be at least 2 characters\";\n } elseif($namelen > $max){\n $errors[] = \"name must be less than 255 characters\";\n }\n\n if($emaillen < $minemail){\n $errors[] = \"email must be at least 3 characters\";\n } elseif($emaillen > $max){\n $errors[] = \"email must be less than 255 characters\";\n }\n\n if(empty($name)){\n $errors[] = \"name is required\";\n }\n\n if(empty($email)){\n $errors[] = \"email cannot be left empty\";\n }\n\n if(!filter_var($email, FILTER_VALIDATE_EMAIL)){\n $errors[] = \"invalid email\";\n }\n\n echo \"<ul>\";\n foreach ($errors as $error) {\n echo \"<li>$error<\/li>\";\n }\n echo \"<\/ul>\";\n\n}\n<\/code><\/pre>\nIt could still be improved, but however, this should get you started!<\/p>\n<\/p><\/div>\n
