How to call a function inside of another function in PHP OOP - php

Question

I'm making my own custom CMS using PHP Object Oriented... I have made a page where a main admin of a site can add another admin. In order to do this I made this form:
<form role="form" method="POST" action="">
<div class="box-body">
<div class="form-group">
<label>User name</label>
<input type="text" class="form-control" placeholder="Enter username" name="uname" required>
</div>
<div class="form-group">
<label for="exampleInputEmail1">Email address</label>
<input type="email" class="form-control" id="exampleInputEmail1" placeholder="Enter email" name="email" required>
</div>
<div class="form-group">
<label for="exampleInputPassword1">Temporary password</label>
<input type="password" class="form-control" id="exampleInputPassword1" placeholder="Enter password" name="pass" required>
</div>
<div class="form-group">
<label>Group admin</label>
<select class="form-control">
<option>Main Admin</option>
<option>Administrator</option>
<option>Content Creator</option>
<option>Analyst</option>
</select>
</div>
</div>
<div class="box-footer">
<button name="submit" type="submit" class="btn btn-primary">Submit</button>
</div>
</form>
Then I added this as action file:
if (isset($_POST['submit'])) {
$username = $_POST['uname'];
$email = $_POST['email'];
$password = $_POST['pass'];
$registration = new Register();
$registration->CheckUname($username,$email);
}
So as you can see I have called a class called Register and in this class I coded this:
class Register {
private $db;
public function __construct() {
$this->db = new Connection();
$this->db = $this->db->dbConnect();
}
public function CheckUname($username,$email) {
if(!empty($username)&&($email)) {
$chk1 = $this->db->prepare("SELECT username FROM admins WHERE user_name= ?");
$chk1->bindParam(1,$username);
$chk1->execute();
if($chk1->rowCount() == 1)
{
$notice['username_exists'] = "Try different username";
} else {
$chk2 = $this->db->prepare("SELECT email FROM admins WHERE email_address= ?");
$chk2->bindParam(1,$email);
$chk2->execute();
if($chk2->rowCount() == 1)
{
$notice['email_exists'] = "The email address that you have entered is already exists in database";
}else{
// I want to call the NewAdmin function here
}
}
}
}
public function NewAdmin($username,$email,$password) {
if(!empty($username)&&!empty($email)&&!empty($password)) {
$reg = $this->db->prepare("INSERT INTO admins (user_name, email_address, password_hash) VALUES ( '?', '?', '?')");
$reg->bindParam(1,$username);
$reg->bindParam(2,$email);
$reg->bindParam(2,$password);
$reg->execute();
}
}
}
Basically I tried to check if that username already exists or not then I also checked if the email exists and if not I want to call the NewAdmin function so the admin can be inserted to db. The problem is I don't know how to do that inside of the CheckUname function. Any help please ?
Also I've got another question which is why the errors that should be produced when the user enter a username or email that already exists in database does not shown! However I have set a variable for this:
if($chk1->rowCount() == 1) {
$notice['username_exists'] = "Try different username";
} else {
$chk2 = $this->db->prepare("SELECT email FROM admins WHERE email_address= ?");
$chk2->bindParam(1,$email);
$chk2->execute();
if($chk2->rowCount() == 1) {
$notice['email_exists'] = "The email address that you have entered is already exists in database";
} else {
// I want to call the NewAdmin function here
}
}
I have also set the error in the page like this:
if(isset($notice['username_exists'])) {
echo "<div class='alert alert-danger'><strong>Hey!</strong> ".$notice['username_exists'].".</div>";
}
if(isset($notice['email_exists'])) {
echo "<div class='alert alert-danger'><strong>Hey!</strong> ".$notice['email_exists'].".</div>";
}
But no errors appears on the page while submitting a username or an email that exists in the db!

Use $this->NewAdmin($username,$email,$password) inside the CheckUname() function of Register class. You can call same class function inside another class by using $this. $this represents the current class object.
