Php Codeigniter 3表单验证未按预期工作

CI3文档明确指出，“由于您还没有告诉表单验证类验证任何内容，因此默认情况下它返回FALSE（boolean FALSE）。

run（）

方法仅在成功应用了您的规则且没有任何失败的情况下返回TRUE。”

    if ($this->form_validation->run() == FALSE) {

        $this->load->view($this->mh_template, $this->data);


    }   else {

        $my_time_zone   = $this->input->post('timezones');
        $user_id        = $this->ion_auth->user()->row()->id;
        $setting_insert_or_update = 'user_time_zone';
        $this->MH_user_settings_model->mh_insert_or_update_setting($setting_insert_or_update, $my_time_zone, $user_id);
        $message = array(   'message'   => 'Success - Timezone updated',
                            'class'     => 'success',  // must be warning, danger, success or info.
                        );
        $this->data['alert'] = bootstrap_alert($message);
        $this->session->set_flashdata('message', $this->data['alert'] );              
        redirect('/MH_app_private/mh_app_settings');
    }

我有下面的方法snipplet。显然，在第一个视图中，视图总是会发出“警告-ooops something gours”但没有验证错误（）。我该如何着手解决这个问题？请检查一下表格是否是$U POST？关于如何完成的最佳方式或建议是什么？bootstrap_alert（）只是将错误或成功消息包装到引导警报中

    if ($this->form_validation->run() == FALSE) {
        $message = array(   'message'   => 'Warning - Ooops something went wrong '.validation_errors(),
                            'class'     => 'danger',  // must be warning, danger, success or info.
                    );
        $this->data['alert'] = bootstrap_alert($message);
        $this->load->view($this->mh_template, $this->data);
    }   else {
        $my_time_zone   = $this->input->post('timezones');
        $user_id        = $this->ion_auth->user()->row()->id;
        $setting_insert_or_update = 'user_time_zone';
        $this->MH_user_settings_model->mh_insert_or_update_setting($setting_insert_or_update, $my_time_zone, $user_id);
        $message = array(   'message'   => 'Success - Timezone updated',
                            'class'     => 'success',  // must be warning, danger, success or info.
                        );
        $this->data['alert'] = bootstrap_alert($message);
        $this->load->view($this->mh_template, $this->data); 
    }

    if ($this->form_validation->run() == FALSE) {

        $this->load->view($this->mh_template, $this->data);


    }   else {

        $my_time_zone   = $this->input->post('timezones');
        $user_id        = $this->ion_auth->user()->row()->id;
        $setting_insert_or_update = 'user_time_zone';
        $this->MH_user_settings_model->mh_insert_or_update_setting($setting_insert_or_update, $my_time_zone, $user_id);
        $message = array(   'message'   => 'Success - Timezone updated',
                            'class'     => 'success',  // must be warning, danger, success or info.
                        );
        $this->data['alert'] = bootstrap_alert($message);
        $this->session->set_flashdata('message', $this->data['alert'] );              
        redirect('/MH_app_private/mh_app_settings');
    }

这就是我最终要做的：

    if ($this->form_validation->run() == FALSE) {

        $this->load->view($this->mh_template, $this->data);


    }   else {

        $my_time_zone   = $this->input->post('timezones');
        $user_id        = $this->ion_auth->user()->row()->id;
        $setting_insert_or_update = 'user_time_zone';
        $this->MH_user_settings_model->mh_insert_or_update_setting($setting_insert_or_update, $my_time_zone, $user_id);
        $message = array(   'message'   => 'Success - Timezone updated',
                            'class'     => 'success',  // must be warning, danger, success or info.
                        );
        $this->data['alert'] = bootstrap_alert($message);
        $this->session->set_flashdata('message', $this->data['alert'] );              
        redirect('/MH_app_private/mh_app_settings');
    }

//设置表单规则 $this->form_validation->set_规则（“时区”、“时区”、“必需”）

    if ($this->form_validation->run() == FALSE) {

        $this->load->view($this->mh_template, $this->data);


    }   else {

        $my_time_zone   = $this->input->post('timezones');
        $user_id        = $this->ion_auth->user()->row()->id;
        $setting_insert_or_update = 'user_time_zone';
        $this->MH_user_settings_model->mh_insert_or_update_setting($setting_insert_or_update, $my_time_zone, $user_id);
        $message = array(   'message'   => 'Success - Timezone updated',
                            'class'     => 'success',  // must be warning, danger, success or info.
                        );
        $this->data['alert'] = bootstrap_alert($message);
        $this->session->set_flashdata('message', $this->data['alert'] );              
        redirect('/MH_app_private/mh_app_settings');
    }

检查请求是否为POST显示或不显示警告。

我没有意识到我可以使用以下内容格式化验证错误（）

    if ($this->form_validation->run() == FALSE) {

        $this->load->view($this->mh_template, $this->data);


    }   else {

        $my_time_zone   = $this->input->post('timezones');
        $user_id        = $this->ion_auth->user()->row()->id;
        $setting_insert_or_update = 'user_time_zone';
        $this->MH_user_settings_model->mh_insert_or_update_setting($setting_insert_or_update, $my_time_zone, $user_id);
        $message = array(   'message'   => 'Success - Timezone updated',
                            'class'     => 'success',  // must be warning, danger, success or info.
                        );
        $this->data['alert'] = bootstrap_alert($message);
        $this->session->set_flashdata('message', $this->data['alert'] );              
        redirect('/MH_app_private/mh_app_settings');
    }

$this->form_validation->set_error_delimiters('<div class="error">', '</div>');  

$this->form\u validation->set\u error\u分隔符（“”，）；

这最终解决了问题

你能发布你的整个函数以便我们检查剩下的东西吗？你加载了form_验证库了吗？在初始视图中，没有错误，但是，显示了消息数组（没有验证错误）。在post上，当我故意出错时，消息数组会显示验证错误。成功也是在适当的时候展现出来的。问题在于最初的观点。是的，form_验证已加载。我很好奇这是如何解决问题的。你能给我看看吗？

    if ($this->form_validation->run() == FALSE) {

        $this->load->view($this->mh_template, $this->data);


    }   else {

        $my_time_zone   = $this->input->post('timezones');
        $user_id        = $this->ion_auth->user()->row()->id;
        $setting_insert_or_update = 'user_time_zone';
        $this->MH_user_settings_model->mh_insert_or_update_setting($setting_insert_or_update, $my_time_zone, $user_id);
        $message = array(   'message'   => 'Success - Timezone updated',
                            'class'     => 'success',  // must be warning, danger, success or info.
                        );
        $this->data['alert'] = bootstrap_alert($message);
        $this->session->set_flashdata('message', $this->data['alert'] );              
        redirect('/MH_app_private/mh_app_settings');
    }
