Question

这是我的控制器profileinfo.php

<?php
class Profileinfo extends CI_Controller {

    function index()
    {

        $this->load->helper(array('form', 'url'));
        $this->load->model('aluminsert','', TRUE);
        $this->load->library('form_validation');

        $this->form_validation->set_rules('name', 'Name', 'required');
        $this->form_validation->set_rules('branch', 'Bramch', 'required');
        $this->form_validation->set_rules('academicinterest', 'Academic Interest', 'required');
        $this->form_validation->set_rules('internshipdetail', 'Internship Details', 'required');
        $this->form_validation->set_rules('interest_hobbies', 'Interest and hobbies', 'required');
        $this->form_validation->set_rules('personalblog', 'Personal Blog', 'required');
        $this->form_validation->set_rules('facebookprofile', 'Facebook Profile', 'required');
        $this->form_validation->set_rules('linkedinprofile', 'Linkedin Profile', 'required');
        $this->form_validation->set_rules('homecity', 'Home city', 'required');
        $this->form_validation->set_rules('country', 'country', 'required');
        $this->form_validation->set_rules('higherdegree', 'Higher Degree', 'required');
        $this->form_validation->set_rules('collegeofeducation', 'College of Education', 'required');
        $this->form_validation->set_rules('officialemail', 'Official Email', 'required');
        $this->form_validation->set_rules('careerinterests', 'Career Interest', 'required');
        $this->form_validation->set_rules('presentemployer', 'Present Employer', 'required');
        $this->form_validation->set_rules('presentjob', 'Present Job', 'required');
        $this->form_validation->set_rules('previousemployer', 'Previous Employee', 'required');
        $this->form_validation->set_rules('startupname', 'Startup Name', 'required');

        if ($this->form_validation->run() == FALSE)
        {
            $this->load->view('alumprofile');

        }
        else
        {
            $alumdata = array(
            'Name' => $this->input->post('name'),
            'Branch' => $this->input->post('branch'),
            'Academic Interest' => $this->input->post('academicinterest'),
            'Internship Details' => $this->input->post('internshipdetail'),
            'Interest and hobbies' => $this->input->post('interest_hobbies'),
            'personalblog' => $this->input->post('personalblog'),
            'Facebook profile' => $this->input->post('facebookprofile'),
            'Linkedin profile' => $this->input->post('linkedinprofile'),
            'Home city' => $this->input->post('homecity'),
            'country' => $this->input->post('country'),
            'Higher Degree' => $this->input->post('higherdegree'),
            'College of Education' => $this->input->post('collegeofeducation'),
            'Official Email' => $this->input->post('officialmail'),
            'Career Interest' => $this->input->post('careerinterests'),
            'Present Employer' => $this->input->post('presentemployer'),
            'Present Job' => $this->input->post('presentjob'),
            'Previous Employee' => $this->input->post('previousemployer'),
            'Startup Name' => $this->input->post('startupname'),
            );
            // Transfering Data To Model
            $this->insert->alum_insert($alumdata);
            $this->load->view('registration_success');
        }
    }
}
?>

这里的模型是aluminsert.php

<?php
class Aluminsert extends CI_Model{
    function __construct() {
        parent::__construct();
    }
    function alum_insert($alumdata){

        $this->db->insert('user_detail', $alumdata);
    }
}
?>

表单验证正在运行，在提交表单后，显示的错误是：致命错误：在第61行的C：\ wamp \ www \ ci \ application \ controllers \ profileinfo.php中的非对象上调用成员函数alum_insert（）

Answer 1

错误在于下面的代码。您正试图通过＆＃39;插入＆＃39;来调用方法。在这种情况下，模型中不存在的类。

$this->insert->alum_insert($alumdata);
$this->load->view('registration_success');

您的模型被称为＆＃39; Aluminsert＆＃39;你用来插入的方法称为＆＃39; alum_insert＆＃39;所以你应该这样做。

$this->aluminsert->alum_insert($alumdata);
$this->load->view('registration_success');

Answer 2

在codeigniter中我们需要加载数据库。所以有两种方式

您可以自动加载或
在任何需要的地方装载。

在 autoload.php 中，您必须写下以下行。

$autoload['libraries'] = array('database');

OR

您还可以通过以下方式加载： -

$this->load->database();

肯定会对你有所帮助。
