codeigniter 中的动态字段验证

Question

我有一个用我自己的表单构建器构建的表单，我的表单构建器类似于 WordPress 的 Gravity 表单。除验证外，一切正常。每次我提交表单时，它都会返回 true。

特别是，我正在验证select 字段，因为用户可以从网络检查器编辑值并提交值，这就是为什么我要根据保存动态表单的数据库中的已保存值检查该值。 这是我的尝试

where $post is $_POST[] array, $postKey is fieldName, & $postValue is submitted value by user.

public function validate()
{
    $post = $this->ci->input->post();
    //check form tempering
    if(empty($post)) 
        return false;

    $formId = $post['form_id'];
    //get form from db
    $data=[];
    $this->ci->db->select('formData');
    $this->ci->db->where('formId', $formId);
    $query = $this->ci->db->get(TBL_FORM_DATA);
    if($query->num_rows() > 0)
    {
        $data = $query->row();
    }
    if(empty($data) ) 
        return false;
    //unset submit button and 0 if occurs

    unset($post['submit']);
    unset($post['0']);

    //decode json
    $data = json_decode($data->formData,true);
    $fields = $data['field'];
    //debug($fields);
    //iterate post values and keys

    foreach ($post as $postKey => $postValue) 
    {
        //echo '<br>'.$postKey;
        if(strpos($postKey, '@'))
        {
            list($fieldName,$field_id) = explode('@', $postKey);

            $field_display_name = ucwords(str_replace('_', ' ', $fieldName));

            if(strpos($field_id,'|')) {
                list($field_id,$price) = explode('|', $field_id);
            }

            $field = $fields[$field_id];
            //debug($field['choice'],false);

            if(isset($field['choice']) && (isset($field['choice']['label']) && isset($field['choice']['value'])) )
            {
                /*if(!in_array($postValue, $field['choice']['value'])) 
                {*/
                    //$list = implode(',', $field['choice']['value']);

                    $this->ci->form_validation->set_rules($postKey,$field_display_name,'callback_check_field['.$list.']');
                    /*$this->ci->form_validation->set_rules($postKey, $field_display_name,"in_list[".$list."]",
                        array('in_list' => 'Invalid Selection. Please Select from available choices.')
                    );*/
                /*}*/
            }

            if(isset($field['required']) && $field['required']=='on'){
                $this->ci->form_validation->set_rules($postKey, $field_display_name,'required|trim');
            }

            //$duplicate = isset($field['no_duplicate']) ? true : false;
            //$this->ci->form_validation->set_rules('form_id',' ','required');
            //$this->ci->form_validation->set_rules('inkform_total',' ','required');    
        }
        $this->ci->form_validation->set_error_delimiters('<div class="clearfix"></div><p class="alert alert-danger">','</p>');

        return $this->ci->form_validation->run();

    }


    //echo validation_errors();

}

检查选择字段值的回调函数

function check_field($field,$list)
{ 
    if(!is_array($list)) {
        $list = explode(',', $list);
    }
    if(!in_array($field, $list)){
        $this->ci->form_validation->set_message('check_field','Invalid Post');
        return false;
    }else{
        return true;
    }

}

稍后我只想访问validate() 函数进行验证。

移动

$this->ci->form_validation->set_error_delimiters('<div class="clearfix"></div><p class="alert alert-danger">','</p>');
return $this->ci->form_validation->run();
