I want to know what is wrong with the form in my code.
<?php
if(isset($_POST['submit'])) {
$arrayName = array("TeacherA", "TeacherB", "TeacherC" , "TeacherD", "TeacherE");
$minimum = 5;
$maximum = 10;
$name = $_POST['yourName'];
$email = $_POST['yourEmail'];
if(strlen($name) < $minimum) {
echo "Your name should be longer than 5 characters";
}
if(strlen($name) > $maximum) {
echo "Your name should not be longer than 10 characters";
}
if(!in_array($name,$arrayName)){
echo "Please do register with us before you can login";
} else {
echo "Welcome!";
}
}
?>

I ran the code locally, but couldn't get the results I wanted.
The result I want is that if I do not enter a name in the "Your Name" field, the result should be displayed:
Please register before logging in

If the "Your Name" field is empty, its strlen($name) should be 0, the first if statement is true, and Your name should be longer than 5 characters
You can try this:
<?php
if (isset($_POST['submit'])) {
$arrayName = array("TeacherA", "TeacherB", "TeacherC", "TeacherD", "TeacherE");
$minimum = 5;
$maximum = 10;
$name = $_POST['yourName'];
$email = $_POST['yourEmail'];
if (empty($name)) {
echo "Please do register with us before you can login";
} else {
if (strlen($name) < $minimum) {
echo "Your name should be longer than 5 characters";
} else {
if (strlen($name) > $maximum) {
echo "Your name should be less than 10 characters";
} else {
if (in_array($name, $arrayName)) {
echo "Welcome!";
} else {
echo "Your login is not correct";
}
}
}
}
}
?>
i used empty() to test if the field empty
and i used if-else statements because i want the script to stop if it finds a 'true' condition
in your script you can use return; but that will exit the rest of your script
have a nice code :)
