Ionic Registration Validation with PDO

[valentinayounes]

I’m trying to validate my registration. However data is entered in the database when this part of my code is in comment :

else
								
 if(strlen($password)<7 || strlen($password)>15)
	echo "<p>Password must be between 7 and 15 characters!</p>";
	
else
 {  
//INSERT function
 }     

Also none of the if content is running i only get {"message":"Please fill in all fields."} as response in my localhost page.

What might the problem be ?

This is my php file :

    try{
		
	$res1  = $pdo->prepare("SELECT p_username FROM account_info WHERE p_username LIKE :p_username");
	$num_rows1 = $res1->fetchColumn();
		
	$res2  = $pdo->prepare("SELECT a_username FROM account_info WHERE a_username LIKE :a_username");
	$num_rows2 = $res2->fetchColumn();
		
				
		if ($num_rows1==0  && $num_rows2==0)
		{
			if($p_username &&  a_username)
			{
				
				 if($password==$vpassword)
				{
					if(strlen($p_username)>25||strlen($a_username)>25)
					{
						echo "<p>Max limit for username are 25 characters</p>";
					}
								
				/*	else
								
						if(strlen($password)<7 || strlen($password)>15)
						echo "<p>Password must be between 7 and 15 characters!</p>";
								
					else
					{   */
					
						$sql  = "INSERT INTO account_info (a_username,p_username, password, vpassword) 
						VALUES(:a_username,:p_username, :password, :vpassword)";
							
						$stmt    = $pdo->prepare($sql);	

						$stmt->bindParam(':a_username', $a_username, PDO::PARAM_STR);
						$stmt->bindParam(':p_username', $p_username, PDO::PARAM_STR);
						$stmt->bindParam(':password', $password, PDO::PARAM_STR);
						$stmt->bindParam(':vpassword', $vpassword, PDO::PARAM_STR);

						$stmt->execute();

						echo json_encode(array('message' => 'Congratulations the record was added to the database'));
					/* }  */   
				} 
				else 
					echo json_encode(array('message' => 'Your passwords do not match!'));
			}
			else 
				echo json_encode(array('message' => 'Please fill in all fields.'));
	}	
	else
		echo json_encode(array('message' => 'This username already exists, please choose another one.')); 
				
	}	
     // Catch any errors in running the prepared statement
     catch(PDOException $e)
     {
        echo $e->getMessage();
     }
?>

Thank you in advance!

You have PHP notices disabled, otherwise you’d have seen the constant-to-string conversion notice.

I think you also need to look at the ‘elseif’ statement, too.
