致命错误：在第450行的 ... \ libraries \ Form_validation.php 中调用未定义的方法stdClass :: load（）

if($_POST) { $this->load->helper(array('form', 'url')); $this->load->library('form_validation'); $val = $this->form_validation; $val->set_rules('content[title]', 'Title', 'trim|required'); $val->set_rules('content[subtitle]', 'Subtitle', 'trim'); $val->set_rules('content[description]', 'description', 'trim'); if ($val->run() AND $this->db->insert('content', $content)) { // query done } }

请帮我解决这个问题....

Answer 1

将您的input names替换为标题，副标题，说明并尝试使用此代码

$this->load->helper(array('form', 'url'));
 $this->load->library('form_validation');
 if ($this->input->post()) {
        $this->form_validation->set_rules('title', 'Title', 'trim|required');
        $this->form_validation->set_rules('subtitle', 'Subtitle', 'trim');
        $this->form_validation->set_rules('title', 'Description', 'required');

        $data['content'] = array(
            'db_field_name' => $this->input->post('title'),
            'db_field_name' => $this->input->post('subtitle'),
            'db_field_name' => $this->input->post('description'),
        );

        if ($this->form_validation->run()){
            $this->db->insert('content', $data['content']);
        }
    }

如果您使用表单验证并且所有用于多个实例，则可以在config / autoload.php中定义帮助程序和库。另请参阅input_field名称以获取验证规则。

$this->load->helper(array('form', 'url'));
$this->load->library('form_validation');
if ($this->input->post()) {
    $this->form_validation->set_rules('title', 'Title', 'trim|required');
    $this->form_validation->set_rules('subtitle', 'Subtitle', 'trim');
    $this->form_validation->set_rules('title', 'Description', 'required');      

    if ($this->form_validation->run() == TRUE) {
        //Your DB operation
        $this->data['formdata'] = array(
            'db_field_title' => $this->input->post('title'),
            'db_field_subtitle' => $this->input->post('subtitle'),
            'db_field_description' => $this->input->post('description')
        );
        $this->db->insert('content', $this->data['content']);
    } else {
        //Show error message
        echo validation_errors();
    }
}

Answer 3

在你的情况下，我认为缺少语言文件
您必须在 system / language / english文件夹中检查是否有form_validation_lang.php可用。缺少form_Validation_lang.php，您必须放置该文件

第450行上的库\ Form_validation.php中的CI错误
