When to start the site already request the login

Navigation
4

I'm creating a website and I have a question. How do I do when the user enters the URL address or click a button that goes to admin.html, and automatically appears the login page? or as soon as you start admin.html already appear first the login page so that it will then open admin.html

Of course if I were to think about doing the button I put it as href. But if when the user enters the url address, there will not appear the login page. how could I do it?

My following files:

login.php connection.php AdminAgenda.html

login.php: 

<?php 
include("php/conexao.php");

if(isset($_POST['email']) && strlen($_POST['email']) > 0){

    if(!isset($_SESSION))
        session_start();

    $_SESSION['email'] = $mysqli -> escape_string($_POST['email']);
    $_SESSION['senha'] = $_POST['senha'];


    $sql_code = "SELECT senha, codigo FROM usuario WHERE email = '$_SESSION[email]'";
    $sql_query = $mysqli -> query($sql_code) or die ($mysqli -> error);
    $dado = $sql_query->fetch_assoc();
    $total = $sql_query-> num_rows;


    if($total == 0){
        $erro[] = "Este email não pertence a nenhum usuário.";
    }
    else{
        if($dado['senha'] == $_SESSION['senha']){

            $_SESSION['usuario'] = $dado['codigo'];

        } else{

            $erro[] = "Senha incorreta.";
        }

    }

    if(count($erro) == 0 || !isset($erro)){
        echo "<script>alert('Login efetuado com sucesso... Seja bem vindo'); location.href='AdmAgenda.html';</script>";
    }

}


?>



<html>
<head></head>
<body>
<?php if(count($erro) > 0)
        foreach($erro as $msg){
            echo "<p>$msg</p>";
        }


    ?>

    <form method="POST" action="">
    <input value="" type="text" placeholder="email" name="email">
    <input type="password" name="senha">

        <input type="submit" value="Entrar">

Taking the idea of the friend LocalHost I would make an include / require of a php file that validates whether the user is logged in or not on your system, that's because already thinking long term and growing your system.

This is valid because if your system grows you will always call the same validation file and if you need to change something the maintenance will be faster and simpler than changing the validation files by files.

In your index.php it would look like this: 

<?php require_once 'valida.php';?>// AQUI chama o arquivo de validacao

<!DOCTYPE html>
    <html lang="pt-br" ng-app="AngularADM">

    <head>

// Restante do codigo HTML

And in your validation file, which we call here valida.php you put the validation script: 

<?php 
 //verifica se o usuário não esta logado
 if(!isset($_SESSION['usuario']) || empty($_SESSION['usuario']){
     header('location:login.php');
  }else{
     header('location:AdmimAgenda.php');
  }
 ?>

This way you can change the form of validation whenever you need it quickly, changing only one file, and you can direct the user to the page you want if you already have a valid session.

Now on every page that needs to be validated, just do the include / require of the valida.php file

Well, if I understand correctly, you will have to put in the first few lines of the code, you need the login, the instruction requiring the login, and for that it needs to be .php .

So the first step is to save your AdmimAgenda.html as AdmimAgenda.php . And then insert just before the header of your page the verification if the user is logged in. Then AdmimAgenda.php will look something like this: 

<?php 
 //verifica se o usuário esta não logado
 if(!isset($_SESSION['usuario']) || empty($_SESSION['usuario']){
 // caso ele não estiver logado, exibe o link para redirecionar para o login
    echo "<a href='login.php'> Faça o login para continuar</a>";
 // e cancela o carregamento do resto da pagina...
  return;
  }
 ?>

What is the real difference between these three ways of switching from one activity to another? Function to duplicate maturities in n parcels?
