在 codeigniter 中执行插入查询后出现空白页

Question

执行以下查询后，codeigniter 显示空白页，我认为插入查询中存在语法错误，也无法打印查询。请帮忙

我的模型代码如下：

function add_new_user($email,$password,$username)
{

    $sqls="INSERT INTO pr_users (username,userpass,email,departmentid,userroleid,managerid,userlevel,branchid,is_global,registrationtime,timemodified,modifierid,status,deleted,temppass,temppassvalidtill,lastlogin,lastrefresh,lastloginip,if_online,pfield) values ('".$email."','".65e1b655a6d6f4cbed20554d3b52521a743afdc0."','".$email."','".1."','".4."','".10."','".4."','".2."','".0."','".0."','".1491557947."','".1."','".1."','".0."','".."','".0."','".1492084067."','".1492084083."','".::1."','".0."','".unfold983$."')";
    $query=$this->db->query($sqls);

    $result = $this->db->last_query();  
    return $result;

}

Answer 1

替换行：

$this->db->last_query();

与：

$result = $this->db->last_query();  
return $result;

Answer 2

像这样重写你的插入语句：检查你的最后一个参数 also.It 在我看来，你需要转义 '$'

`$sqls="INSERT INTO pr_users  (username,userpass,email,departmentid,userroleid,managerid,userlevel,branchid,is_global,registrationtime,timemodified,modifierid,status,deleted,temppass,temppassvalidtill,lastlogin,lastrefresh,lastloginip,if_online,pfield) values ('".$email."','65e1b655a6d6f4cbed20554d3b52521a743afdc0','".$email."','1','4','10','4','2','0','0','1491557947','1','1','0','','0','1492084067','1492084083','::1','10','unfold983$')";`

Answer 3

试试这个

function add_new_user($email,$password,$username)
{
    $sqls="INSERT INTO pr_users (username,userpass,email,departmentid,userroleid,managerid,userlevel,branchid,is_global,registrationtime,timemodified,modifierid,status,deleted,temppass,temppassvalidtill,lastlogin,lastrefresh,lastloginip,if_online,pfield) values ('$email','65e1b655a6d6f4cbed20554d3b52521a743afdc0','$email','1','4','10','4','2','0','0','1491557947','1','1','0','','0','1492084067','1492084083','1','0','unfold983$')";
    $query=$this->db->query($sqls);

    if ($this->db->affected_rows() > 0) {
        echo "Success";
        # return TRUE;
    } 
    else {
        echo "failed";
        # return FALSE;
    }

}

Note: Make sure in index.php(in root) environment is development

define('ENVIRONMENT', 'development'); # line 21
