          <div id="basic-modal-content">
            <div id="winsign">

          <form action="" method="post" onSubmit="validate();"> 


           <?php

       include 'core/init.php';


       if (empty($_POST) === false) {
           $username = $_POST['username'];
           $password = $_POST['password'];

       if (empty($username) === true || empty($password) === true) {
        $errors[]= 'You need to enter a username and password';
               } else if (user_exists($username) === false) {
        $errors[]= 'We cant\'t find username. Have you registered?';
        } else if (user_active($username) === false) {
        $errors[]= 'You haven\'t acticated your account!';  
            } else {
        $login = login($username, $password);
        if ($login === false) {
            $errors[] = 'That username/password combination is incorrect';      
            } else {
            $_SESSION['user_id'] = $login;  
            header('Location: sign_in.php');
            exit();
            }
        } 
            print_r($errors);
    }
       ?>


            <span id="tpos">Username:</span><br>
            <input type="text" name="username" class="sbutton" id="modalbox" placeholder="Username">
            <br><br><span id="tpos">Password:</span>
            <br><input type="password" name="password" class="sbutton" id="modalbox" placeholder="Password">
            <br><br><input type="checkbox" name="checkbox" class="cbutton"><span id="ttext">Remember me</span>
            <br><input type="submit" value="Sign In" name="signin" id="bsubmit">
            </input>
            </form>

That is in modal window and when i clicked submit button is not checking for php errors in first click and reload index.php When i clicked second time is there error but in first click is not showing errors and reload page index…

I think you’re looking for an onSubmit for your form.

Try something like this:

<form name="formname" action="index.php" method="post" onSubmit="validate();">
</form>
