Question

我有一个表单来插入数据。当我单击提交按钮数据时不插入到database.submit表单而不填写表单验证不起作用。任何人都可以帮助我。

控制器

//load client from table

    $data['client'] = $this->project_list_model->get_client();

    $this->form_validation->set_rules('location', 'Location', 'required');
    $this->form_validation->set_rules('name', 'Project Name', 'required');
    $this->form_validation->set_rules('category', 'Category', 'required');
    $this->form_validation->set_rules('str_date', 'Start Date', 'required');
    $this->form_validation->set_rules('end_date', 'End Date', 'required');

    if ($this->form_validation->run() == FALSE) {
        $this->load->view('add_project', $data);
    } else {
        $data = array(
        //'staff_id' => ($this->session->userdata['logged_in']['id']),
                        'project_name' => $this->input->post('name'),
                        'client_id' => $this->input->post('client'),
                        'location' =>  md5($this->input->post('location')),
                        'start_date' => $this->input->post('str_date'),
                        'end_date' => $this->input->post('end_date')
                        );
        $result = $this->project_list_model->new_project($data);
        $data['message_display'] = 'Add Project Successfully !';
        $this->load->view('add_project', $data);

    }
}

模型

//    add new project
function new_project($data){

    // Inserting in Table(students) of Database(college)
    $this->db->insert('project', $data);

}

查看

<?php
echo form_open('project_list/add_project');
?>

<!--display successful message-->

if (isset($message_display)) {

请使用以下功能在表单中打印验证错误

<?php echo validation_errors() ?>

OR

<?php echo form_error('name');  //name will be name of your input field ?>

表单数据不会在codeigniter中插入数据库
