当我选择上载.xlsx文件时，它会导入工作表中显示的所有数据，但最后它显示错误 错误号：1048 列“名称”不能为空 为什么数据库不为空类型时名称为空？ 我确实选择了不同的excel工作表，但发生了相同的事情
这是我的控制器 Import_Controller.php
class Import_Controller extends CI_Controller {
public function __construct() {
parent::__construct();
$this->load->model('Import_Model');
$this->load->library('excel');
if (!$this->ion_auth->logged_in())
{
// redirect them to the login page
redirect('auth/login', 'refresh');
}
}
public function index(){
$data['content'] = 'admin/import/Import';
$this->load->view('inc/template',$data);
}
public function import()
{
if(isset($_FILES["file"]["name"]))
{
$path = $_FILES["file"]["tmp_name"];
$object = PHPExcel_IOFactory::load($path);
foreach($object->getWorksheetIterator() as $worksheet)
{
$highestRow = $worksheet->getHighestRow();
$highestColumn = $worksheet->getHighestColumn();
for($row=2; $row<=$highestRow; $row++)
{
$name = $worksheet->getCellByColumnAndRow(0, $row)->getValue();
$size = $worksheet->getCellByColumnAndRow(1, $row)->getValue();
$manufacturer = $worksheet->getCellByColumnAndRow(2, $row)->getValue();
$model_no = $worksheet->getCellByColumnAndRow(3, $row)->getValue();
$model_name = $worksheet->getCellByColumnAndRow(4, $row)->getValue();
$description = $worksheet->getCellByColumnAndRow(5, $row)->getValue();
$width = $worksheet->getCellByColumnAndRow(6, $row)->getValue();
$depth = $worksheet->getCellByColumnAndRow(7, $row)->getValue();
$kit_pn = $worksheet->getCellByColumnAndRow(8, $row)->getValue();
$color = $worksheet->getCellByColumnAndRow(9, $row)->getValue();
$remarks = $worksheet->getCellByColumnAndRow(10, $row)->getValue();
$arr['dm'] = array('name' => $name,'size' => $size);
$arr['im'] = array('manufacturer' => $manufacturer,'model_no' => $model_no,'model_name' => $model_name,'description' => $description,'width' => $width,'depth' => $depth);
$arr['ak'] = array('kit_pn' => $kit_pn,'color' => $color,'remarks' => $remarks);
$new_array[] = $arr;
}
}
$this->Import_Model->insert($new_array);
echo 'Data Imported successfully';
}
}
}
我的模型是： Import_model.php
class Import_Model extends CI_Model
{
public function getValues($value){
$data = $this->db->get_where('dispenser_model', $value['dm'])->row();
if(empty($data)){
$this->db->insert('dispenser_model',$value['dm']);
//$dm_insert_id = $this->db->insert_id();
} else{
$dm_insert_id = $data->id;
}
$data1 = $this->db->get_where('im_manufacturer', $value['im'])->row();
if(empty($data1)){
$this->db->insert('im_manufacturer',array(
'manufacturer' =>$value['im']['manufacturer'],
'model_no' => $value['im']['model_no'],
'model_name' => $value['im']['model_name'],
'description' => empty($value['im']['description']) ? $value['im']['description'] : NULL,
'width' => $value['im']['width'],
'depth' => $value['im']['depth']
));
//echo $this->db->last_query();
$im_insert_id = $this->db->insert_id();
} else{
$im_insert_id = $data1->id;
}
$data2 = $this->db->get_where('adaptor_kit',$value['ak'])->row();
if(empty($data2)){
$this->db->insert('adaptor_kit',$value['ak']);
$ak_insert_id = $this->db->insert_id();
} else{
$ak_insert_id = $data2->id;
}
$data3 = $this->db->get_where('model', array(
'dm_id' => $dm_insert_id,
'im_id' =>$im_insert_id,
'ak_id'=> $ak_insert_id))->row();
if(empty($data3)){
$this->db->insert('model',array(
'dm_id' => $dm_insert_id,
'im_id' =>$im_insert_id,
'ak_id'=> $ak_insert_id));
$model_insert_id = $this->db->insert_id();
} else{
$model_insert_id = $data->id;
}
}
public function insert($new_array)
{
$my_array = [];
foreach ($new_array as $value) {
$my_array[] = $this->getValues($value);
echo '<pre>' ; print_r($value);
}
}
}
