Vérifiez le nom d'utilisateur correct sur le formulaire de connexion personnalisé

J'ai utilisé le tutoriel de Jeff Star pour créer mon propre formulaire de connexion personnalisé http://digwp.com/2010/12/login-register-password-code/ . Cela fonctionne très bien, mais j'ai un problème. Sur le formulaire de réinitialisation du mot de passe, si quelqu'un entre son nom d'utilisateur de manière incorrecte (pour qu'il ne vérifie pas), il est renvoyé au nom par défaut wp-login.php? Action = lostpassword avec le message d'erreur.

Y at-il un moyen de rediriger vers ma propre page d'erreur?

Merci!

Le code qu'il a posté dans ce tutoriel (très agréable BTW) est la forme du module "réinitialiser le mot de passe" intégré qui redirige vers le login.php en cas d'erreur, mais vous pouvez le modifier et construire le vôtre en fonction à la page du modèle, changez:

<form method="post" action="<?php echo site_url('wp-login.php?action=lostpassword', 'login_post') ?>" class="wp-user-form">
    <div class="username">
        <label for="user_login" class="hide"><?php _e('Username or Email'); ?>: </label>
        <input type="text" name="user_login" value="" size="20" id="user_login" tabindex="1001" />
    </div>
    <div class="login_fields">
        <?php do_action('login_form', 'resetpass'); ?>
        <input type="submit" name="user-submit" value="<?php _e('Reset my password'); ?>" class="user-submit" tabindex="1002" />
        <?php $reset = $_GET['reset']; if($reset == true) { echo '<p>A message will be sent to your email address.</p>'; } ?>
        <input type="hidden" name="redirect_to" value="<?php echo $_SERVER['REQUEST_URI']; ?>?reset=true" />
        <input type="hidden" name="user-cookie" value="1" />
    </div>
</form>

à:

<form method="post" action="<?php echo $_SERVER['REQUEST_URI']; ?>" class="wp-user-form">
<div class="username">
    <label for="user_login" class="hide"><?php _e('Username or Email'); ?>: </label>
    <input type="text" name="user_login" value="" size="20" id="user_login" tabindex="1001" />
</div>
<div class="login_fields">
    <?php do_action('login_form', 'resetpass'); ?>
    <input type="submit" name="user-submit" value="<?php _e('Reset my password'); ?>" class="user-submit" tabindex="1002" />

Voici une version mise à jour du code de @bainternet avec les erreurs de syntaxe corrigées, la suggestion de @Val et le générateur de clé de wp-login.php 3.4.2:

global $wpdb;
$username = trim($_POST['user_login']);
$user_exists = false;
// First check by username
if ( username_exists( $username ) ){
    $user_exists = true;
    $user = get_user_by('login', $username);
}
// Then, by e-mail address
elseif( email_exists($username) ){
        $user_exists = true;
        $user = get_user_by_email($username);
}else{
    $error[] = '<p>'.__('Username or Email was not found, try again!').'</p>';
}
if ($user_exists){
    $user_login = $user->user_login;
    $user_email = $user->user_email;

    $key = $wpdb->get_var($wpdb->prepare("SELECT user_activation_key FROM $wpdb->users WHERE user_login = %s", $user_login));
    if ( empty($key) ) {
        // Generate something random for a key...
        $key = wp_generate_password(20, false);
        do_action('retrieve_password_key', $user_login, $key);
        // Now insert the new md5 key into the db
        $wpdb->update($wpdb->users, array('user_activation_key' => $key), array('user_login' => $user_login));
    }

    //create email message
    $message = __('Someone has asked to reset the password for the following site and username.') . "\r\n\r\n";
    $message .= get_option('siteurl') . "\r\n\r\n";
    $message .= sprintf(__('Username: %s'), $user_login) . "\r\n\r\n";
    $message .= __('To reset your password visit the following address, otherwise just ignore this email and nothing will happen.') . "\r\n\r\n";
    $message .= network_site_url("wp-login.php?action=rp&key=$key&login=" . rawurlencode($user_login), 'login') . "&redirect_to=".urlencode(get_option('siteurl'))."\r\n";
    //send email meassage
    if (FALSE == wp_mail($user_email, sprintf(__('[%s] Password Reset'), get_option('blogname')), $message))
    $error[] = '<p>' . __('The e-mail could not be sent.') . "<br />\n" . __('Possible reason: your Host may have disabled the mail() function...') . '</p>';
}

            }

Je rencontrais toujours des problèmes avec la clé de réinitialisation qui ne fonctionnait pas correctement, le lien dans l'e-mail me redirigeait vers la page de réinitialisation du mot de passe standard avec le paramètre URL indiquant un problème avec la clé. J'ai donc suivi de plus près le fichier wp-login.php. et inclus l'objet $ wp_hasher, cela corrigeait le problème et la réinitialisation du mot de passe dans l'email fonctionne maintenant

if (($_SERVER['REQUEST_METHOD'] === (string) 'POST') && (isset($_POST['reset_pass']))) {

// Acccess global properties
global $wpdb, $wp_hasher;


// Variables
$error_pass_reset = array();
$username         = (string) trim($_POST['user_login']);
$user_exists      = (bool)   false;



// ---- USERNAME OR EMAIL EXISTS ---- //
if (username_exists($username)) {
    $user_exists = (bool)   true;
    $user        = (object) get_user_by('login', $username);
} // end if

else if (email_exists($username)) {
    $user_exists = (bool)   true;
    $user        = (object) get_user_by('email', $username);
} // end else if

else {
    $error_pass_reset[] = '<p>Username or Email was not found, please try again.</p>';
} // end else



// ---- USER EXISTS ---- //
if ($user_exists === (bool) true) {
    // Variables
    $user_login = (string) $user -> user_login;
    $user_email = (string) $user -> user_email;


    // Generate password reset key
if (empty($key)) {
    $key = (string) wp_generate_password(20, false);

    do_action('retrieve_password_key', $user_login, $key);


    // Create the $wp_hasher object
    if (empty($wp_hasher)) {
        require_once(ABSPATH . WPINC . '/class-phpass.php');

        $wp_hasher = new PasswordHash(8, true);
    }

    // Reset key with hasher applied (MD5 has string output)
    $hashed = (string) time() . ':' . $wp_hasher -> HashPassword($key);


    // Insert the new key into the database
    $wpdb -> update(
        $wpdb -> users,
        array(
            'user_activation_key' => $hashed
        ),
        array(
            'user_login' => $user_login
        )
    );
} // end if


    // Email message
    $message = (string)
    'Someone requested that the password be reset for the following account:' . "\r\n\r\n" .

    get_option('siteurl') . "\r\n\r\n" .

    'Username: ' . $user_login . "\r\n\r\n" .
    'If this was a mistake, just ignore this email and nothing will happen.' . "\r\n\r\n" .
    'To reset your password, visit the following address:' . "\r\n\r\n" .

    get_option('siteurl') . '/wp-login.php?action=rp&key=' . $key . '&login=' . $user_login . "\r\n";


    // Send email
    if ((bool) false === wp_mail($user_email, get_option('blogname') . ' Password Reset', $message)) {
        $error_pass_reset[] = '<p>The e-mail could not be sent at this time.</p>' . "\n";
    } // end if
} // end if


// Send the rest password email
do_action('login_form', 'resetpass');

} // end if (($_SERVER['REQUEST_METHOD'] === (string) 'POST') && (isset($_POST['reset_pass'])))
