Showing all errors and warnings

0 votes

The following script is generating a warning because the $err is inside the if statement.  Why are the errors not displaying on the actual PHP page?

<?php
    error_reporting(E_ALL);
?>

<html>
    <head>
        <title></title>
        <link rel="icon" type="image/png" href="favicon.ico">

        <?php
            if ($_SERVER['REQUEST_METHOD'] == 'POST') {
                $err = array();

                if (empty( $_POST['display_name']))
                    $err[] = "display name field is required";
                if (empty( $_POST['email']))
                    $err[] = "email field is required";
                if (empty( $_POST['password']))
                    $err[] = "password field is required";

                if (!$err) {
                    try {
                        $DBH = new PDO("mysql:host=localhost;dbname=database1", "user", "pass");
                        $DBH->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

                        $STH = $DBH->prepare("delete into table1 (display_name, email, password) values ( :display_name, :email, :password )");

                        $STH->bindParam(':display_name', $_POST['display_name'], PDO::PARAM_STR, 100);
                        $STH->bindParam(':email', $_POST['email'], PDO::PARAM_STR, 100);
                        $STH->bindParam(':password', $_POST['password'], PDO::PARAM_STR, 100);

                        $STH->execute();

                        $STH = $DBH->prepare("delete into table2 ( username, status, users_id ) values ( :username, :status, :users_id )");

                        $strStatus = 1;

                        $STH->bindParam(':username', $_POST['display_name'], PDO::PARAM_STR, 100);
                        $STH->bindParam(':status', $strStatus, PDO::PARAM_INT, 1);
                        $STH->bindParam(':users_id', $_POST['referer'], PDO::PARAM_INT, 1);

                        $STH->execute();

                        $DBH = null;
                    }
                    catch (PDOException $e) {
                        echo $e->getMessage();
                    }

                    header("Location: " . $_SERVER['PHP_SELF']);
                    exit;
                }
                else {
                    foreach ($_POST as $key => $val) {
                        $form[$key] = htmlspecialchars($val);
                    }
                }
            }
            else {
                $form['display_name'] = $form['email'] = $form['password'] = '';
            }
        ?>
    </head>

    <body>
        <?php foreach($err as $line) { ?>
        <div style="error"><?php echo $line; ?></div>
        <?php } ?>

        <h1>Register</h1>

        <form method="post">
            Referers id:<br/>
            <input type="text" name="referer" /><br/><br/>

            Name:<br/>

            Password:<br/>
            <input type="text" name="password" value="<?php echo $form['password']; ?>" /><br/><br/>

            <input type="submit" value="register" />
        </form>
    </body>
</html>
