问题

我有这个小部件代码，它使用“使用Google登录”按钮来获取用户凭据，并最终获取他们的Google评论。按钮工作正常，我能够获取凭据和CSRF令牌。我尝试将它们保存在WordPress中以供以后使用，但这两个值不会保存，其他值会保存。

public function form( $instance ) {
    $title = ! empty( $instance['title'] ) ? $instance['title'] : __( 'Google Maps Reviews', 'text_domain' );
    $place_id = ! empty( $instance['place_id'] ) ? $instance['place_id'] : '';
    $api_key = ! empty( $instance['api_key'] ) ? $instance['api_key'] : '';

    if ( !empty( $_POST['credential'] ) ) {
        $google_credential = $_POST['credential'];
    } else {            
        $google_credential = $instace['google_credential'];
        echo "instance credential: "; 
    }

    if ( !empty( $_POST['g_csrf_token'] ) ) {
        $google_csrf_token = $_POST['g_csrf_token'];
    } else {
        $google_csrf_token = $instace['google_csrf_token'];
    }

    ?>
    <?php if(empty($_POST['credential'])){ ?>
        <script src="https://accounts.google.com/gsi/client" async defer></script>
    <?php } ?>

I have this widget code, which uses Sign In with Google button to get users credentials and eventually fetch their Google Reviews. Button works fine, and I&#39;m able to get credentials and CSRF token. I&#39;m trying to save them inside WordPress for later use, however this two values won&#39;t save, the other values do save.

public function form( $instance ) {
$title = ! empty( $instance['title'] ) ? $instance['title'] : __( 'Google Maps Reviews', 'text_domain' );
$place_id = ! empty( $instance['place_id'] ) ? $instance['place_id'] : '';
$api_key = ! empty( $instance['api_key'] ) ? $instance['api_key'] : '';

	if ( !empty( $_POST[&#39;credential&#39;] ) ) {
$google_credential = $_POST[&#39;credential&#39;];
} else {			
$google_credential = $instace[&#39;google_credential&#39;];
echo &quot;instance credential: &quot;; 
}
if ( !empty( $_POST[&#39;g_csrf_token&#39;] ) ) {
$google_csrf_token = $_POST[&#39;g_csrf_token&#39;];
} else {
$google_csrf_token = $instace[&#39;google_csrf_token&#39;];

得分: 1

你有两个小的拼写错误，应该是instance（带有“N”）而不是instace。

$google_credential = $instance['google_credential'];
echo "instance credential: ";
}

if (!empty($_POST['g_csrf_token'])) {

$google_csrf_token = $_POST['g_csrf_token'];
} else {
$google_csrf_token = $instance['google_csrf_token'];
}

我不能确定这将解决你所有的问题，但你应该从这里开始

英文:

You have two small typos of instace where you would expect instance (with "N")

        $google_credential = $instace[&#39;google_credential&#39;];
echo &quot;instance credential: &quot;; 
}
if ( !empty( $_POST[&#39;g_csrf_token&#39;] ) ) {
$google_csrf_token = $_POST[&#39;g_csrf_token&#39;];
} else {
$google_csrf_token = $instace[&#39;google_csrf_token&#39;];

I can't be sure this will solve all your problems but for certain you should begin here :}
