php - ユーザーがアップロードしたアバターをログインフォームに表示するにはどうすればよいですか？

Question

ここで何をしようとしているのかを説明するために最善を尽くします。

ユーザーがホームページから直接ログインできるワードプレスのログインフォームを作成しました。このフォームには、ログインしているプロファイルのアバターが含まれています。これが私が思いついたコードです。

<div id="loginDiv">

<!-- If User Is Logged In Display This -->

<?php if (is_user_logged_in()) { ?>

Welcome <strong><?php echo $user_identity ?></strong>.

<?php echo get_avatar($id_or_email,$size='100'); ?>

<form name="loginform" id="loginform" action="<?php echo wp_logout_url(); ?>" method="post">

<input type="submit" name="wp-submit" id="wp-submit" value="LOG OUT" />
<a href="http://www.bignotch.com/wp-admin/profile.php">EDIT YOUR PROFILE</a>

<input type="hidden" name="redirect_to" value="<?php bloginfo('url'); ?>" />
</form>

<!-- If User Is NOT Logged In Display This -->

<? } else { ?>

<form name="loginform" id="loginform" action="<?php bloginfo('url'); ?>/wp-login.php" method="post">

<label for="log">Username</label> <input type="text" name="log" id="user_login" class="input" value="" size="20" tabindex="10" /></p>
<label for="pwd">Password</label> <input type="password" name="pwd" id="user_pass" class="input" value="" size="20" tabindex="20" /></p>

<input type="submit" name="wp-submit" id="wp-submit" value="LOG IN" /> <input type="button" value="SIGNUP" onClick="parent.location='<?php bloginfo('url'); ?>/wp-login.php?action=register'" />

<a href="<?php bloginfo('url'); ?>/wp-login.php?action=lostpassword">Lost your password?</a>

<input type="hidden" name="redirect_to" value="<?php bloginfo('url'); ?>/members" />
<input type="hidden" name="testcookie" value="1" />
</form>

<? } ?></div>

ここでの問題は、ワードプレスでは、アバターを作成するためにユーザーが「gravatar」サイトにアクセスする必要があることです。これは私には良くありません。そこで、ユーザーが自分のユーザーの写真をアップロードできるSimple Local Avatarsプラグインをインストールしましたが、その画像をカスタムログインフォームに表示する方法がわかりません。

ログインフォームにアバターを表示するために使用するコードの部分は次のとおりです。

<?php echo get_avatar($id_or_email,$size='100'); ?>

しかし、Gravatarの画像を取得しようとしているようです。ユーザーがアップロードする画像を取得するためにこれが必要です。これどうやってするの？

使用する代わりに

echo get_avatar($id_or_email,$size='100');

これを呼んでみてください

グローバル$current_user;

echo get_avatar（$ current_user-> id、100）;

まず、プラグインを単純なローカルアバターとbbpressの間に接続して、追加する必要があります。

bbpressテーマフォルダー内のこの行（使用しているテーマ）bbpress-functions.phpセットアップactions（）内

add_action( 'bbp_sla_edit_user_profile', array( 'simple_local_avatars', 'edit_user_profile' ) );

bbpressテーマフォルダのform-user-edit.phpにこの行を追加します

<?php global $current_user; do_action( 'bbp_sla_edit_user_profile', $current_user ); ?>
