我需要一个PHP页面使用wordpress登录验证进行保护。因此，我使用了以下代码：

$args = array(
    \'echo\' => true,
    \'redirect\' => site_url( $_SERVER[\'REQUEST_URI\'] ), 
    \'form_id\' => \'loginform\',
    \'label_username\' => __( \'Username\' ),
    \'label_password\' => __( \'Password\' ),
    \'label_remember\' => __( \'Remember Me\' ),
    \'label_log_in\' => __( \'Log In\' ),
    \'id_username\' => \'user_login\',
    \'id_password\' => \'user_pass\',
    \'id_remember\' => \'rememberme\',
    \'id_submit\' => \'wp-submit\',
    \'remember\' => true,
    \'value_username\' => NULL,
    \'value_remember\' => false );

wp_login_form( $args );

但重定向不起作用。当我以管理员用户身份登录时，我会被重定向到wp admin页面。当我以用户身份登录时，我会被重定向到首页：-s

所以，我尝试了这个：

function login_redirect( $redirect_to, $request, $user ){
    return home_url(site_url( $_SERVER[\'REQUEST_URI\'] ));
}

add_filter( \'login_redirect\', \'login_redirect\', 10, 3 );

不起作用…

所以我试着用这个(http://codex.wordpress.org/Plugin_API/Filter_Reference/login_redirect)

完整代码：

<?php
header( \'Cache-Control: no-store, no-cache, must-revalidate\' );
header( \'Cache-Control: post-check=0, pre-check=0\', false );
header( \'Expires: Mon, 26 Jul 1997 05:00:00 GMT\' );
header( \'Last-Modified: \' . gmdate( \'D, d M Y H:i:s\' ) . \' GMT\' );
header( \'Pragma: no-cache\' );

require(\'../wp-load.php\' );

get_header();

function my_login_redirect( $redirect_to, $request, $user ){
    //is there a user to check?
    global $user;
    if( isset( $user->roles ) && is_array( $user->roles ) ) {
        //check for admins
        if( in_array( "administrator", $user->roles ) ) {
            // redirect them to the default place
            return $redirect_to;
        } else {
            return home_url();
        }
    }
    else {
        return $redirect_to;
    }
}

add_filter("login_redirect", "my_login_redirect", 10, 3);

if ( is_user_logged_in() ) 
{
    echo "Hello. You are logged in<br>";
    wp_loginout();
}
else
{
    echo "Hello. please login<br>";

    wp_login_form();
    echo"<a href=\\"".wp_lostpassword_url( get_permalink() )."\\" title=\\"Lost Password\\">I lost my password</a>";
}

get_footer(); 
?>

仍然。。。没有成功。

我正在使用WP 3.8版

===========================================

添加了功能。主题中的php文件

<?php
require_once(\'inc/Sidebar.php\');

register_nav_menu( \'top-menu\', \'Top Menu\' ); 

/*
 * Extending excerpt
 */
function custom_excerpt_length( $length ) {
    return 350;
}
add_filter( \'excerpt_length\', \'custom_excerpt_length\', 999 );


//removing default "Continue Reading from Excerpt
function sbt_custom_excerpt_more( $output ) {
    return preg_replace(\'/<a[^>]+>Continue reading.*?<\\/a>/i\',\'\',$output);
}
add_filter( \'get_the_excerpt\', \'sbt_custom_excerpt_more\', 20 );

//redirecting all users to dashboard (only subscribers on home)

function redirect_users($user_login, $user) {
    if(!current_user_can("subscriber")) {
        wp_redirect(get_admin_url());
    }
}
add_action(\'wp_login\', \'redirect_users\', 1, 2);

function wpse126853_redirect_to_request( $redirect_to, $request, $user ) {
    // instead of using $redirect_to we\'re redirecting back to $request
    return $request;
}
add_filter( \'login_redirect\', \'wpse126853_redirect_to_request\', 10, 3 );
?>

function wpse126853_redirect_to_request( $redirect_to, $request, $user ) {
    // instead of using $redirect_to we\'re redirecting back to $request
    return $request;
}
add_filter( \'login_redirect\', \'wpse126853_redirect_to_request\', 10, 3 );
