Codeigniter 3 应用程序错误：如果标题中有变音符号，则无法将标题转换为 slug

Question

我正在使用 Codeigniter 3.1.8 和 Bootstrap 4.[=15= 开发一个基本的博客应用程序]

单曲 post URL 由 post 的标题和 url_title($this->input->post('title'), 'dash', TRUE) 组成。整个post创建函数是这样的：

public function create() {

    // Only logged in users can create posts
    if (!$this->session->userdata('is_logged_in')) {
        redirect('login');
    }

    $data = $this->get_data();
    $data['tagline'] = "Add New Post";

    if ($data['categories']) {
        foreach ($data['categories'] as &$category) {
            $category->posts_count = $this->Posts_model->count_posts_in_category($category->id);
        }
    }

    $this->form_validation->set_rules('title', 'Title', 'required');
    $this->form_validation->set_rules('desc', 'Short description', 'required');
    $this->form_validation->set_rules('body', 'Body', 'required');
    $this->form_validation->set_error_delimiters('<p class="error-message">', '</p>');

    if($this->form_validation->run() === FALSE){
        $this->load->view('partials/header', $data);
        $this->load->view('dashboard/create-post');
        $this->load->view('partials/footer');
    } else {
        // Create slug (from title)
        $slug = url_title($this->input->post('title'), 'dash', TRUE);
        $slugcount = $this->Posts_model->slug_count($slug, null);
        if ($slugcount > 0) {
            $slug = $slug."-".$slugcount;
        }

        // Upload image
        $config['upload_path'] = './assets/img/posts';
        $config['allowed_types'] = 'jpg|jpeg|png';
        $config['max_size'] = '2048';

        $this->load->library('upload', $config);

        if(!$this->upload->do_upload()){
            $errors = array('error' => $this->upload->display_errors());
            $post_image = 'default.jpg';
        } else {
            $data = array('upload_data' => $this->upload->data());
            $post_image = $_FILES['userfile']['name'];
        }

        $this->Posts_model->create_post($post_image, $slug);
        $this->session->set_flashdata('post_created', 'Your post has been created');
        redirect('/');
    }
}

我确信它运行良好，直到我在标题中添加了一个带有变音符号的 post。 "La mulți ani România!" 导致 slug la-mul??i-ani-rom??nia 而不是 la-multi-ani-romania。

我试图用 Codeigniter 的 convert_accented_characters() 解决这些问题：

$slug = convert_accented_characters(url_title($this->input->post('title'), 'dash', TRUE));

即使我确实加载了测试助手，它也不工作：

$autoload['helper'] = array('url', 'form', 'date', 'text');

我还有哪些其他选择？我该如何解决这个问题？

Answer 1

我使用 url_title() 和 convert_accented_characters() 的顺序是错误的。

这是正确的一个：

$slug = url_title(convert_accented_characters($this->input->post('title')), 'dash', TRUE);

现在可以正常使用了。
