Question

我正在建立一个网站，我有一个注册客户端的功能，我需要选择从下拉列表中的数据库中选择，然后将其发送到用户表，我得到2个错误atm和我无法找到解决方案。

这是我的模特：

class Home extends CI_Model{

//SQL

    function get_prodTYPE(){
        $this->db->select()->from('producttype')->where('active',1);
        $query=$this->db->get();
        return $query->result_array();
    }

    function get_COUNTRY(){
        $this->db->select()->from('pais');
        $this->db->order_by("id_pais", "asc");
        $result = $this->db->get('pais');
        $resultado = array();
        if($result->num_rows() > 0){
            $resultado[''] = 'please select';
            foreach($result->result_array() as $row){
                $resultado[$row['id_pais']] = $row['Pais'];
            }
        }
    return $resultado;
    }

然后我有一个大文件，这是注册的主要部分这是我的控制器：

function register(){

    if(!$this->session->userdata('userID')){

        $data['prodTYPE']=$this->home->get_prodTYPE();
        $data['info']=$this->home->get_info();
        $data['country']=$this->home->get_COUNTRY();


        //validacao

我这里有错误的form_helper部分：

if ( ! function_exists('form_dropdown'))
    {
    function form_dropdown($name = '', $options = array(), $selected = array(), $extra = '')
    {
        if ( ! is_array($selected))
        {
            $selected = array($selected);
        }

    // If no selected state was submitted we will attempt to set it automatically
    if (count($selected) === 0)
    {
        // If the form name appears in the $_POST array we have a winner!
        if (isset($_POST[$name]))
        {
            $selected = array($_POST[$name]);
        }
    }

    if ($extra != '') $extra = ' '.$extra;

    $multiple = (count($selected) > 1 && strpos($extra, 'multiple') === FALSE) ? ' multiple="multiple"' : '';

    $form = '<select name="'.$name.'"'.$extra.$multiple.">\n";

    foreach ($options as $key => $val)
    {
        $key = (string) $key;

        if (is_array($val) && ! empty($val))
        {
            $form .= '<optgroup label="'.$key.'">'."\n";

            foreach ($val as $optgroup_key => $optgroup_val)
            {
                $sel = (in_array($optgroup_key, $selected)) ? ' selected="selected"' : '';

                $form .= '<option value="'.$optgroup_key.'"'.$sel.'>'.(string) $optgroup_val."</option>\n";
            }

            $form .= '</optgroup>'."\n";
        }
        else
        {
            $sel = (in_array($key, $selected)) ? ' selected="selected"' : '';

            $form .= '<option value="'.$key.'"'.$sel.'>'.(string) $val."</option>\n";
        }
    }

    $form .= '</select>';

    return $form;
}
}

这是2个错误

希望有人可以帮助我谢谢:)

你的问题很简单，在这部分代码中：

        } else {//registo
            $data=array(
                'username'=>$_POST['username'],

您正在将$data重置为新阵列。对于一个简单的解决方案，请使用array_merge（）：

        } else {//registo
            $additional_data=array(
                'username'=>$_POST['username'],
                'userTYPE'=>'user',
                'password'=>sha1($_POST['password']),
                'email'=>$_POST['email'],
                'active'=>$_POST['newsletter']==null?0:1,
                'name'=>$_POST['name'],
                'contact'=>$_POST['contact'],
                'country'=>$_POST['country'],
                'address'=>$_POST['address'],
                'postalCODE'=>$_POST['postalCODE'],
                'postalCODE2'=>$_POST['postalCODE2'],
                'city'=>$_POST['city'],
                'taxpayerNUMBER'=>$_POST['taxpayerNUMBER']                      
            );
            array_merge($data, $additional_data);
