几天来我一直在寻找答案。我有一个项目，我需要创建一个前端表单，该表单将请求一组信息，并使用它创建一个后期草稿，供客户在管理面板上批准或不批准。到目前为止，我能够创建一个短代码，在前端显示HTML表单，获取所需信息，并根据我的自定义帖子类型创建草稿。最大的问题是上传图像，我似乎无法让它工作，甚至无法在任何地方找到解决方案。

这是我当前的代码：

add_action ( \'init\', \'create_cpt_teste\');

function create_cpt_teste() {
    register_post_type (\'cpt-teste\',
        array(
            \'labels\' => array(
                \'name\' => \'CPT Teste\',
                \'singular_name\' => \'CPT Teste\',
                \'add_new\' => \'Adicionar Novo\',
                \'add_new_item\' => \'Adicionar Novo CPT Teste\',
                \'edit\' => \'Editar\',
                \'edit_item\' => \'Editar CPT Teste\',
                \'new_item\' => \'Novo CPT Teste\',
                \'view\' => \'Visualizar\',
                \'view_item\' => \'Visualizar CPT Teste\',
                \'search_items\' => \'Pesquisar CPT Teste\',
                \'not_found\' => \'Nenhum CPT Teste Encontrado\',
                \'not_found_in_trash\' => \'Nenhum CPT Teste Encontrado na Lixeira\',
                \'parent\' => \'CPT Teste Superior\'
            ),

            \'public\' => true,
            \'publicly_queryable\' => true,
            \'show_ui\' => true,
            \'show_in_menu\' => true,
            \'query_var\' => true,
            \'rewrite\' => array( \'slug\' => \'cpt-teste\' ),
            \'capability_type\' => \'post\',
            \'has_archive\' => true,
            \'hierarchical\' => false,
            \'menu_position\' => 25,
            \'supports\' => array( \'title\', \'editor\', \'thumbnail\' ),
            \'menu_icon\' => \'dashicons-store\'
        )
    );
}
