javascript - Display alert message that's inside an action file, in another file
405
So I have this php action file:
<?php
session_start();
require 'config.php';
if (isset($_POST['action']) && $_POST['action'] == 'signup') {
$stmt1 = "SELECT * FROM users where username='" . $_POST['username'] . "'";
$ret1 = mysqli_query($conn, $stmt1);
$rowcount1 = mysqli_fetch_assoc($ret1);
if (empty($rowcount1)) {
$query = "INSERT INTO users (username, password, email, cpf)VALUES( '" . $_POST['username'] . "', '" . $_POST['password'] . "', '" . $_POST['email'] . "', '" . $_POST['cpf'] . "')";
//echo $query;exit;
echo mysqli_query($conn, $query);
} else {
header("Location:signup.php");
echo '<script language="javascript">';
echo 'alert("User is already registered.")';
echo '</script>';
}
}
This else statement becomes true because I can see it in the console, but, I'm trying to display this alert message in another file called "signup.php".
I want to display the alert message right inside this small div:
<div class="cont">
</div>
I tried to do it with "header("Location:signup.php");" as you can see but no idea on how to make it work.
Any ideas on how I can do that?

Solution:
Header('Location:') will redirect the user's browser. Nothing else will be displayed on the web page because the browser is being redireced. You need to add the tag to the page signup.php.
