我试图允许用户更新网站前端的自定义user\\u元字段。它在后端工作正常，但在前端页面上，当按update时，页面变为空白，但仍在更新用户元。有人能帮我解决空白页的问题吗。
我最初发现了这个问题How to edit a user profile on the front end?. 我将在下面发布代码，我想他们一定是页面顶部的php出错导致了这种情况。
上一篇帖子的答案：
你可以通过复制你的主题页面来做到这一点。php到一个名为user profile之类的新文件。php，并在其顶部添加以下代码：
/* 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\', $current_user->ID);
wp_redirect( get_permalink() );
exit;
}
}
?>
然后将该页的循环替换为以下循环：
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
<div id="post-<?php the_ID(); ?>">
<div class="entry-content entry">
<?php the_content(); ?>
<?php if ( !is_user_logged_in() ) : ?>
<p class="warning">
<?php _e(\'You must be logged in to edit your profile.\', \'profile\'); ?>
</p><!-- .warning -->
<?php else : ?>
<?php if ( count($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-username -->
<p class="form-username">
<label for="last-name"><?php _e(\'Last Name\', \'profile\'); ?></label>
<input class="text-input" name="last-name" type="text" id="last-name" value="<?php the_author_meta( \'last_name\', $current_user->ID ); ?>" />
</p><!-- .form-username -->
<p class="form-email">
<label for="email"><?php _e(\'E-mail *\', \'profile\'); ?></label>
<input class="text-input" name="email" type="text" id="email" value="<?php the_author_meta( \'user_email\', $current_user->ID ); ?>" />
</p><!-- .form-email -->
<p class="form-url">
<label for="url"><?php _e(\'Website\', \'profile\'); ?></label>
<input class="text-input" name="url" type="text" id="url" value="<?php the_author_meta( \'user_url\', $current_user->ID ); ?>" />
</p><!-- .form-url -->
<p class="form-password">
<label for="pass1"><?php _e(\'Password *\', \'profile\'); ?> </label>
<input class="text-input" name="pass1" type="password" id="pass1" />
</p><!-- .form-password -->
<p class="form-password">
<label for="pass2"><?php _e(\'Repeat Password *\', \'profile\'); ?></label>
<input class="text-input" name="pass2" type="password" id="pass2" />
</p><!-- .form-password -->
<p class="form-textarea">
<label for="description"><?php _e(\'Biographical Information\', \'profile\') ?></label>
<textarea name="description" id="description" rows="3" cols="50"><?php the_author_meta( \'description\', $current_user->ID ); ?></textarea>
</p><!-- .form-textarea -->
<?php
//action hook for plugin and extra fields
do_action(\'edit_user_profile\',$current_user);
?>
<p class="form-submit">
<?php echo $referer; ?>
<input name="updateuser" type="submit" id="updateuser" class="submit button" value="<?php _e(\'Update\', \'profile\'); ?>" />
<?php wp_nonce_field( \'update-user\' ) ?>
<input name="action" type="hidden" id="action" value="update-user" />
</p><!-- .form-submit -->
</form><!-- #adduser -->
<?php endif; ?>
</div><!-- .entry-content -->
</div><!-- .hentry .post -->
<?php endwhile; ?>
<?php else: ?>
<p class="no-data">
<?php _e(\'Sorry, no page matched your criteria.\', \'profile\'); ?>
</p><!-- .no-data -->
<?php endif; ?>
剩下要做的就是创建一个新页面并选择“用户配置文件”作为页面模板。
上一页结束
如果有人有解决方案，那会很有帮助的。谢谢。
