从自定义主题选项中提取滑块数据时出错 - Error pulling slider data from custom theme options

Error pulling slider data from custom theme options

我正在尝试使用以下代码从自定义主题选项面板中获取滑块数据。这将返回以下错误

警告：在第 16 行的/home/muratgok/public_html/wp-content/themes/default/page - client.php 中为 foreach（）提供的参数无效

我猜我的语法并不完全正确，但我正在努力看看在哪里。谢谢

        <?php echo $slides = $smof_data['example_slider']; //get the slides array
        foreach ($slides as $slide) {
            echo $slide['title'];
            echo $slide['url'];
            echo $slide['link'];
            echo $slide['description'];
        }
        ?>

下面的主题选项代码

$of_options[] = array(  "name"      => "Slider Options",
                        "desc"      => "Unlimited slider with drag and drop sortings.",
                        "id"        => "example_slider",
                        "std"       => "",
                        "type"      => "slider"
                );

尝试并确保这是一个数组 $smof_data['example_slider']：

    <?php $slides = $smof_data['example_slider']; //get the slides array
    foreach ($slides as $slide) {
        echo $slide['title'];
        echo $slide['url'];
        echo $slide['link'];
        echo $slide['description'];
    }
    ?>
