Réponseen bref,vouspouvez configurer WordPresspour vous connecterpare-mail.

Trois étapes:

• Supprimer lafonction d'authentificationpar défaut
• Ajouter unefonction d'authentificationpersonnalisée
• Remplacez letexte "Nom d'utilisateur" dans wp-login.phppar "E-mail"

Une remarque:

• Nemodifiezpas lesfichiersprincipaux.

Supprimez lafonction d'authentificationpar défaut de WordPress.

WordPress utilise lefiltre " authentifier "poureffectuer une validation supplémentaire lors de la connexion de l'utilisateur.

 remove_filter('authenticate', 'wp_authenticate_username_password', 20);
 

Ajouter unefonction d'authentificationpersonnalisée

 add_filter('authenticate', function($user, $email, $password){

    //Check for empty fields
    if(empty($email) || empty ($password)){        
        //create new error object and add errors to it.
        $error = new WP_Error();

        if(empty($email)){ //No email
            $error->add('empty_username', __('<strong>ERROR</strong>: Email field is empty.'));
        }
        else if(!filter_var($email, FILTER_VALIDATE_EMAIL)){ //Invalid Email
            $error->add('invalid_username', __('<strong>ERROR</strong>: Email is invalid.'));
        }

        if(empty($password)){ //No password
            $error->add('empty_password', __('<strong>ERROR</strong>: Password field is empty.'));
        }

        return $error;
    }

    //Check if user exists in WordPress database
    $user = get_user_by('email', $email);

    //bad email
    if(!$user){
        $error = new WP_Error();
        $error->add('invalid', __('<strong>ERROR</strong>: Either the email or password you entered is invalid.'));
        return $error;
    }
    else{ //check password
        if(!wp_check_password($password, $user->user_pass, $user->ID)){ //bad password
            $error = new WP_Error();
            $error->add('invalid', __('<strong>ERROR</strong>: Either the email or password you entered is invalid.'));
            return $error;
        }else{
            return $user; //passed
        }
    }
}, 20, 3);
 

Remplacez letexte "Nom d'utilisateur" dans wp-login.phppar "E-mail"

Nouspouvons utiliser lefiltre gettext pour remplacer letexte "Nom d'utilisateur"par "E-mail" sansmodifier lesfichiersprincipaux.

 add_filter('gettext', function($text){
    if(in_array($GLOBALS['pagenow'], array('wp-login.php'))){
        if('Username' == $text){
            return 'Email';
        }
    }
    return $text;
}, 20);

Update: I have created a plugin for login, registration and retrieve password with email. https://wordpress.org/plugins/smart-wp-login/

Answer in short, you can configure WordPress to login with email.

Three Steps:

• Remove default authentication function
• Add custom authentication function
• Change text "Username" in wp-login.php to "Email"

One Note:

• Don't edit core files.

Remove WordPress default authentication function.

WordPress uses "authenticate" filter to perform additional validation at user login.

remove_filter('authenticate', 'wp_authenticate_username_password', 20);

Add custom authentication function

add_filter('authenticate', function($user, $email, $password){

    //Check for empty fields
    if(empty($email) || empty ($password)){        
        //create new error object and add errors to it.
        $error = new WP_Error();

        if(empty($email)){ //No email
            $error->add('empty_username', __('<strong>ERROR</strong>: Email field is empty.'));
        }
        else if(!filter_var($email, FILTER_VALIDATE_EMAIL)){ //Invalid Email
            $error->add('invalid_username', __('<strong>ERROR</strong>: Email is invalid.'));
        }

        if(empty($password)){ //No password
            $error->add('empty_password', __('<strong>ERROR</strong>: Password field is empty.'));
        }

        return $error;
    }

    //Check if user exists in WordPress database
    $user = get_user_by('email', $email);

    //bad email
    if(!$user){
        $error = new WP_Error();
        $error->add('invalid', __('<strong>ERROR</strong>: Either the email or password you entered is invalid.'));
        return $error;
    }
    else{ //check password
        if(!wp_check_password($password, $user->user_pass, $user->ID)){ //bad password
            $error = new WP_Error();
            $error->add('invalid', __('<strong>ERROR</strong>: Either the email or password you entered is invalid.'));
            return $error;
        }else{
            return $user; //passed
        }
    }
}, 20, 3);

Change text "Username" in wp-login.php to "Email"

We can use gettext filter to change text "Username" to "Email" without editing core files.

add_filter('gettext', function($text){
    if(in_array($GLOBALS['pagenow'], array('wp-login.php'))){
        if('Username' == $text){
            return 'Email';
        }
    }
    return $text;
}, 20);

I have also written a detailed article at my blog http://www.thebinary.in/blog/wordpress-login-using-email/

C'estpossible,vous devez changer lefiltre dunom.

 // remove the default filter
remove_filter( 'authenticate', 'wp_authenticate_username_password', 20, 3 );
// add custom filter
add_filter( 'authenticate', 'fb_authenticate_username_password', 20, 3 );
function fb_authenticate_username_password( $user, $username, $password ) {

    // If an email address is entered in the username box, 
    // then look up the matching username and authenticate as per normal, using that.
    if ( ! empty( $username ) )
        $user = get_user_by( 'email', $username );

    if ( isset( $user->user_login, $user ) )
        $username = $user->user_login;

    // using the username found when looking up via email
    return wp_authenticate_username_password( NULL, $username, $password );
}
 

Une alternativeest unplugin,là voustrouvez via Google oder dans le repoplugin;peut-être ceplugin .

It's possible, you must change the filter for the name.

// remove the default filter
remove_filter( 'authenticate', 'wp_authenticate_username_password', 20, 3 );
// add custom filter
add_filter( 'authenticate', 'fb_authenticate_username_password', 20, 3 );
function fb_authenticate_username_password( $user, $username, $password ) {

    // If an email address is entered in the username box, 
    // then look up the matching username and authenticate as per normal, using that.
    if ( ! empty( $username ) )
        $user = get_user_by( 'email', $username );

    if ( isset( $user->user_login, $user ) )
        $username = $user->user_login;

    // using the username found when looking up via email
    return wp_authenticate_username_password( NULL, $username, $password );
}

An alternative is an plugin, there you find via Google oder in the plugin repo; maybe this plugin.

En utilisant le code ci-dessus:

 // Change login credentials
// remove the default filter
remove_filter( 'authenticate', 'wp_authenticate_username_password', 20, 3 );
// add custom filter
add_filter( 'authenticate', 'my_authenticate_username_password', 20, 3 );
function my_authenticate_username_password( $user, $username, $password ) {

    // If an email address is entered in the username box, 
    // then look up the matching username and authenticate as per normal, using that.
    if ( ! empty( $username ) ) {
        //if the username doesn't contain a @ set username to blank string
        //causes authenticate to fail
        if(strpos($username, '@') == FALSE){
                $username = '';
            }
        $user = get_user_by( 'email', $username );
        }
    if ( isset( $user->user_login, $user ) )
        $username = $user->user_login;

    // using the username found when looking up via email
    return wp_authenticate_username_password( NULL, $username, $password );
} 
 

Tout ce quenous avions àfaire était de vérifier que lenom d'utilisateurfourni ressemblait aumoins à une-mailet sinon de saboter lenom d'utilisateur.

Using the above code:

// Change login credentials
// remove the default filter
remove_filter( 'authenticate', 'wp_authenticate_username_password', 20, 3 );
// add custom filter
add_filter( 'authenticate', 'my_authenticate_username_password', 20, 3 );
function my_authenticate_username_password( $user, $username, $password ) {

    // If an email address is entered in the username box, 
    // then look up the matching username and authenticate as per normal, using that.
    if ( ! empty( $username ) ) {
        //if the username doesn't contain a @ set username to blank string
        //causes authenticate to fail
        if(strpos($username, '@') == FALSE){
                $username = '';
            }
        $user = get_user_by( 'email', $username );
        }
    if ( isset( $user->user_login, $user ) )
        $username = $user->user_login;

    // using the username found when looking up via email
    return wp_authenticate_username_password( NULL, $username, $password );
} 

All we had to do was check that the provided username at-least looked like a email and if not sabotage the username.

ilest déjà dans WP-CORE!

maintenant wordpresspermet déjà d'enregistrer EMAIL commenom d'utilisateur.mais si vousparlez d'utilisateurs déjàenregistrés,essayez les réponses répertoriées.

it is already in WP-CORE!

now wordpress already allows to register EMAIL as username. but if you are talking about already registered users, then try the listed answers.

De légèresmodifications du code ci-dessus devraient suffirepour créer une solution élégante. La documentationpour le hook d'authentification indique qu'un objet WP_User ou l'objet WP_Error doit être renvoyé.

Le code source de lafonction wp_authenticate_username_password passepar quelques vérifications assez simples;nouspouvons simplement reproduire lafaçon dont ces vérifications sonteffectuéeset créer unnouvel objet WP_Errorpourgérer l'adressee-mail. Alternativement,nouspourrionsmême capturer le code wp_authenticate_username_passwordet lemodifier sinous le voulions,bien que cela sembleinutile àmoins que vousne souhaitiez vraimentpersonnaliser lefonctionnement des choses. Le code ci-dessous devraitfaire l'affaire: (bien queje ne l'aipastestémoi-même ...)

 // Remove the default authentication function
remove_filter( 'authenticate', 'wp_authenticate_username_password', 20, 3 );

// Add the custom authentication function
add_filter( 'authenticate', 'custom_authenticate_username_password', 20, 3 );

function custom_authenticate_username_password( $user, $username, $password ) {

    // Get the WP_User object based on the email address
    if ( ! empty( $username ) ) {
        $user = get_user_by( 'email', $username );
    }

    // Return a customized WP_Error object if a WP_User object was not be returned (i.e. The email doesn't exist or a regular username was provided)
    if ( ! $user ) {
        return new WP_Error( 'invalid_username_email', sprintf( __( '<strong>ERROR</strong>: Invalid username. Please log in with your email address. <a href="%s" title="Password Lost and Found">Lost your password</a>?' ), wp_lostpassword_url() ) );
    }

    // Hand authentication back over to the default handler now that we a have a valid WP_User object based on the email address
    return wp_authenticate_username_password( null, $username, $password );
}
 

Slight modifications to the code above should be all that is needed to create an elegant solution. The documentation for the authenticate hook states that either a WP_User object or WP_Error object should be returned.

The source code for the wp_authenticate_username_password function runs through some pretty simple checks; we can just replicate the way those checks are done, and create a new WP_Error object to deal with the email address. Alternatively, we could even jack the wp_authenticate_username_password code and modify it if we wanted, although that seems unnecessary unless you really want to customize how things function. The code below should do the trick: (Although I haven't tested it myself...)

// Remove the default authentication function
remove_filter( 'authenticate', 'wp_authenticate_username_password', 20, 3 );

// Add the custom authentication function
add_filter( 'authenticate', 'custom_authenticate_username_password', 20, 3 );

function custom_authenticate_username_password( $user, $username, $password ) {

    // Get the WP_User object based on the email address
    if ( ! empty( $username ) ) {
        $user = get_user_by( 'email', $username );
    }

    // Return a customized WP_Error object if a WP_User object was not be returned (i.e. The email doesn't exist or a regular username was provided)
    if ( ! $user ) {
        return new WP_Error( 'invalid_username_email', sprintf( __( '<strong>ERROR</strong>: Invalid username. Please log in with your email address. <a href="%s" title="Password Lost and Found">Lost your password</a>?' ), wp_lostpassword_url() ) );
    }

    // Hand authentication back over to the default handler now that we a have a valid WP_User object based on the email address
    return wp_authenticate_username_password( null, $username, $password );
}
