Question

我使用CodeIgniter作为我开发的框架。我试图将数据插入MySQL数据库的表。数据插入如下。

$dataArray['categoryId'] = $categoryId['id'];
$dataArray['subCategoryId'] = $subTypeId;
$dataArray['title'] = $title;
$dataArray['regionId'] = $regionId;
$dataArray['slogan'] = $slogan;
$dataArray['lastUpdated'] = date('Y-m-d H:i:s');
$dataArray['createdDate'] = date('Y-m-d H:i:s');
$dataArray['state'] = 'Unhide';
$dataArray['status'] = 'Active';
$dataArray['approval'] = 'Incompleted';
$dataArray['user_id'] = $userId;
$this->db->insert($carrentals, $dataArray);
$insertId = $this->db->insert_id();

我的表格如附图所示。

$ insertId始终返回0并且没有数据插入表中。我可以手动将数据插入表中。可能有什么不对？我有AUTO_INCREMENT列作为id。但是没有插入数据并且总是返回0.

编辑：我的实际代码是

$dataArray = [
            'categoryId' => $categoryId['id'],
            'subCategoryId' => $subTypeId,
            'title' => $title,
            'regionId' => $regionId,
            'slogan' => $slogan,
            'lastUpdated' =>date('Y-m-d H:i:s')
        ];
if (empty($_POST['referenceId'])) {
                $dataArray['createdDate'] = date('Y-m-d H:i:s');
                $dataArray['state'] = 'Unhide';
                $dataArray['status'] = 'Active';
                $dataArray['approval'] = 'Incompleted';
                $dataArray['user_id'] = $userId;
                $this->db->insert($carrentals, $dataArray);
                $insertId = $this->db->insert_id();                
                $responseArray = array(
                    'result' => $insertId,
                    'success' => true);
                return $this->set_response($responseArray, REST_Controller::HTTP_OK);
  }

Answer 1

可能返回FALSE而不是零。 setenv MAIL /usr/spool/mail/$USER setenv MATLABPATH /home/users/me/matlab/functions:/home/users/me/matlab/scripts setenv PYTHONPATH /home/users/me/python/modules:/home/users/me/python/scripts set path=( /sbin /bin /usr/bin /usr/local/bin /usr/local/java/bin /usr/bin/X11 ~/bin) if (! $?csh) then if($?prompt) then set prmptchr=$prompt else set prmptchr="/" endif alias setprompt 'set prompt = "$cwd$prmptchr "' # directory name in prompt alias cd 'chdir \!*; setprompt' alias pushd 'pushd \!*; setprompt' alias popd 'popd \!*; setprompt' setprompt endif返回TRUE或FALSE，在继续之前检查结果

insert()

我认为您创建$inserted = $this->db->insert($carrentals, $dataArray); if($inserted) { $responseArray = ['result' => $insertId, 'success' => true]; } else { $responseArray = ['result' => NULL, 'success' => false]; } return $this->set_response($responseArray, REST_Controller::HTTP_OK);的方式没有任何问题。

尝试将 $ dataArray 替换为

$dataArray = array( 'categoryId' => $categoryId['id'],
                    'subCategoryId' => $subTypeId,
                    'title' => $title,
                    'regionId' => $regionId,
                    'slogan' => $slogan,
                    'lastUpdated' => date('Y-m-d H:i:s'),
                    'createdDate' => date('Y-m-d H:i:s'),
                    'state' => 'Unhide',
                    'status' => 'Active',
                    'approval' => 'Incompleted',
                    'user_id' => $userId
                 );
$this->db->insert($carrentals, $dataArray);
$insertId = $this->db->insert_id();

Answer 3

如果$this->db->last_query();或userId为空，请尝试检查categoryId查询的方式，另外检查关系（如果有的话）。

将数据插入表中将返回insertId 0
