Question

我试图将图像添加到文件夹和数据库的路径，但我试图弄清楚如何去做但没有任何工作。请帮忙。这是我的控制器

function index()
{           
    $this->form_validation->set_rules('username', 'username', 'required|trim|xss_clean');           
    $this->form_validation->set_rules('photo', 'photo', 'required|trim|xss_clean');                             
    $this->form_validation->set_rules('password', 'password', 'required|trim|xss_clean');                   

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

    if ($this->form_validation->run() == FALSE) // validation hasn't been passed
    {
        $this->load->view('registration');
    }
    else // passed validation proceed to post success logic
    {
        // build array for the model

        $form_data = array(
                        'username' => set_value('username'),
                        'photo' => set_value('photo'),
                        'password' => set_value('password')                  
                    );

        // run insert model to write data to db

        if ($this->kint_model->SaveForm($form_data) == TRUE) // the information has therefore been successfully saved in the db
        {
            redirect('user_registration/success');   // or whatever logic needs to occur
        }
        else
        {
        echo 'An error occurred saving your information. Please try again later';
        // Or whatever error handling is necessary
        }
    }
}
function success()
{
        echo 'User registered successfully';
}

这是我的模特

class Kint_model extends CI_Model {

    function __construct()
    {
        parent::__construct();
    }

    function SaveForm($form_data)
    {
        $this->db->insert('users', $form_data);

        if ($this->db->affected_rows() == '1')
        {
            return TRUE;
        }

        return FALSE;
    }
}

这是我的观点

<?php // Change the css classes to suit your needs    

$attributes = array('class' => '', 'id' => '');
echo form_open('user_registration', $attributes); ?>

<p>
        <label for="username">username <span class="required">*</span></label>
        <?php echo form_error('username'); ?>
        <br /><input id="username" type="text" name="username"  value="<?php echo set_value('username'); ?>"  />
</p>

<p>
        <label for="photo">photo <span class="required">*</span></label>
        <?php echo form_error('photo'); ?>
        <br /><input id="photo" type="text" name="photo"  value="<?php echo set_value('photo'); ?>"  />
</p>

<p>
        <label for="password">password <span class="required">*</span></label>
        <?php echo form_error('password'); ?>
        <br /><input id="password" type="text" name="password"  value="<?php echo set_value('password'); ?>"  />
</p>

<p>
        <?php echo form_submit( 'submit', 'Submit'); ?>
</p>

<?php echo form_close(); ?>

控制器：

function index()
{           
    $this->form_validation->set_rules('username', 'username', 'required|trim|xss_clean');                        
    $this->form_validation->set_rules('password', 'password', 'required|trim|xss_clean');                   

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

    if ($this->form_validation->run() == FALSE) // validation hasn't been passed
    {
        $this->load->view('registration');
    }
    else 
    {

        $form_data = array(
                        'username' => $this->input->post('username'),
                        'photo' => '',
                        'password' => $this->input->post('password')      
                    );


            $UploadPreferences = array(
               'upload_path'   => './uploads/fullsize',
             'allowed_types' => 'gif|jpg|png',
                'encrypt_name'  => TRUE
              );

         $this->upload->initialize($UploadPreferences);
            $this->upload->do_upload('photo');

            $photoInfo = $this->upload->data();

            $form_data['photo'] = $photoInfo['full_path'];
        if ($this->kint_model->SaveForm($form_data) == TRUE) // the information has therefore been successfully saved in the db
        {
            redirect('user_registration/success');   // or whatever logic needs to occur
        }
        else
        {
        echo 'An error occurred saving your information. Please try again later';
        // Or whatever error handling is necessary
        }
    }
}
function success()
{
        echo 'User registered successfully';
}

查看：

    <?php // Change the css classes to suit your needs    

$attributes = array('class' => '', 'id' => '');
echo form_open('user_registration', $attributes); ?>

<p>
        <label for="username">username <span class="required">*</span></label>
        <?php echo form_error('username'); ?>
        <br /><input id="username" type="text" name="username"  value="<?php echo set_value('username'); ?>"  />
</p>

<p>
        <label for="photo">photo <span class="required">*</span></label>
        <?php echo form_error('photo'); ?>
        <br /><input type="file" name="photo" multiple="multiple" />
</p>

<p>
        <label for="password">password <span class="required">*</span></label>
        <?php echo form_error('password'); ?>
        <br /><input id="password" type="text" name="password"  value="<?php echo set_value('password'); ?>"  />
</p>

<p>
        <?php echo form_submit( 'submit', 'Submit'); ?>
</p>

<?php echo form_close(); ?>
