Comment éditer un profil utilisateur sur le front-end?

Comment puis-je modifier un profil d'utilisateur dans l'interface avec un formulaire?
nom, prénom, nom d'utilisateur, adresse e-mail et mot de passe

Vous pouvez faire cela en copiant le page.php de votre thème dans un nouveau fichier nommé quelque chose comme user-profile.php et en ajoutant tout en haut ce code:

<?php
/**
 * Template Name: User Profile
 *
 * Allow users to update their profiles from Frontend.
 *
 */

/* Get user info. */
global $current_user, $wp_roles;
//get_currentuserinfo(); //deprecated since 3.1

/* Load the registration file. */
//require_once( ABSPATH . WPINC . '/registration.php' ); //deprecated since 3.1
$error = array();    
/* If profile was saved, update profile. */
if ( 'POST' == $_SERVER['REQUEST_METHOD'] && !empty( $_POST['action'] ) && $_POST['action'] == 'update-user' ) {

    /* Update user password. */
    if ( !empty($_POST['pass1'] ) && !empty( $_POST['pass2'] ) ) {
        if ( $_POST['pass1'] == $_POST['pass2'] )
            wp_update_user( array( 'ID' => $current_user->ID, 'user_pass' => esc_attr( $_POST['pass1'] ) ) );
        else
            $error[] = __('The passwords you entered do not match.  Your password was not updated.', 'profile');
    }

    /* Update user information. */
    if ( !empty( $_POST['url'] ) )
        wp_update_user( array( 'ID' => $current_user->ID, 'user_url' => esc_url( $_POST['url'] ) ) );
    if ( !empty( $_POST['email'] ) ){
        if (!is_email(esc_attr( $_POST['email'] )))
            $error[] = __('The Email you entered is not valid.  please try again.', 'profile');
        elseif(email_exists(esc_attr( $_POST['email'] )) != $current_user->id )
            $error[] = __('This email is already used by another user.  try a different one.', 'profile');
        else{
            wp_update_user( array ('ID' => $current_user->ID, 'user_email' => esc_attr( $_POST['email'] )));
        }
    }

    if ( !empty( $_POST['first-name'] ) )
        update_user_meta( $current_user->ID, 'first_name', esc_attr( $_POST['first-name'] ) );
    if ( !empty( $_POST['last-name'] ) )
        update_user_meta($current_user->ID, 'last_name', esc_attr( $_POST['last-name'] ) );
    if ( !empty( $_POST['description'] ) )
        update_user_meta( $current_user->ID, 'description', esc_attr( $_POST['description'] ) );

    /* Redirect so the page will show updated info.*/
  /*I am not Author of this Code- i dont know why but it worked for me after changing below line to if ( count($error) == 0 ){ */
    if ( count($error) == 0 ) {
        //action hook for plugins and extra fields saving
        do_action('edit_user_profile_update', $current_user->ID);
        wp_redirect( get_permalink() );
        exit;
    }
}
?>

puis remplacez la boucle de cette page par celle-ci:

<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
    <div id="post-<?php the_ID(); ?>">
        <div class="entry-content entry">
            <?php the_content(); ?>
            <?php if ( !is_user_logged_in() ) : ?>
                    <p class="warning">
                        <?php _e('You must be logged in to edit your profile.', 'profile'); ?>
                    </p><!-- .warning -->
            <?php else : ?>
                <?php if ( count($error) > 0 ) echo '<p class="error">' . implode("<br />", $error) . '</p>'; ?>
                <form method="post" id="adduser" action="<?php the_permalink(); ?>">
                    <p class="form-username">
                        <label for="first-name"><?php _e('First Name', 'profile'); ?></label>
                        <input class="text-input" name="first-name" type="text" id="first-name" value="<?php the_author_meta( 'first_name', $current_user->ID ); ?>" />

                    </p><!-- .form-textarea -->

                    <?php 
                        //action hook for plugin and extra fields
                        do_action('edit_user_profile',$current_user);

Il ne vous reste plus qu'à créer une nouvelle page et à sélectionner le "profil utilisateur" comme modèle de page.

maintenant si tout cela est trop, vous pouvez utiliser des plugins qui font le travail dur pour vous comme:

• Frontend Modifier le profil
• WP utilisateur Frontend
• Thème Mon Login
• Profil frontal WP
