织梦自定义模型中新增的字段会报错 Call to a member function GetInnerText() on
在织梦自定义模型后，可能会报下面这个错误，Fatal error: Call to a member function GetInnerText() on a non-object in D:\WWW2\ebh\include\customfields.func.php on line 539
解决方案如下：
打开\include\customfields.func.php文件，找到539行：
把$fvalue = trim($ntag->GetInnerText());
替换成：$fvalue = ($ntag=="") ? trim($ntag) :trim($ntag->GetInnerText());

Call to a member function fetch() on a non-object异常
Call to a member function fetch() on a non-object错误
try{
$dsn = "mysql:host=localhost;dbname=db_upan";
$db = new PDO($dsn,"root","");
$sql = "select * form tb_uptype";
$statement = $db->query($sql);
while($result = $statement->fetch(PDO::FETCH_ASSOC )){
echo $result[''genrename''];
}
$db = null;
}catch (PDOException $e){
echo "发生错误。";
}
代码如上： 运行的时候提示错误Fatal error: Call to a member function fetch() on a non-object in C:\xampp\htdocs\upan\test.php on line 7；
请问这是什么原因啊？ 坐等。。。
------解决方案--------------------
$sql = "select * from tb_uptype";
------解决方案--------------------
$sql = "select * form tb_uptype";
应为
$sql = "select * from tb_uptype";
sql 指令错了，自然后继代码也要出错
Call to a member function fetchColumn() on a non-object
采用 pdo 方式连接 mysql
$rs=$conn->query("select count(*) from member where id=0 "); $res=$conn->query("select count(*) from member where mess=0 "); $total = $rs->fetchColumn(); $res_total = $res->fetchColumn();不知道为什么提示 Call to a member function fetchColumn () on a non-object 而且是第二个 fetchColumn () ，为什么第一个 fetchColumn () 不出错呢？$total 也有值，很奇怪
Call to a member function get() on null 这个如何解决呢
Call to a member function get() on null 这个怎么解决呢
class CountController extends Controller{
//核心算法
//用户输入的数据收集
var $planstart;//计划开始时间
var $planend;//计划结束时间
var $plantime;//计划周期
var $goodnum;
var $workernum;
var $workday;//工作制
var $workereff;
var $dutyarr;
//进行赋值
function __construct(){
$this->planstart=$_POST[''pl_start''];
$this->planend=$_POST[''pl_end''];
$this->plantime=$this->planend-$this->planstart;
$this->goodnum=$_POST[''pl_goodnum''];
$this->workernum[0]=$_POST[''pl_opmember''];$this->workernum[1]=$_POST[''pl_psmember''];$this->workernum[2]=$_POST[''pl_exmember''];
$this->workday=$_POST[''pl_workday''];
$this->workereff=8;//每天8个工时
$this->dutyarr=$_POST[''duty_arr''];
}
为什么会有这个提示呢，构造函数里那个地方写错了呢
------解决思路----------------------
你哪边调用了不存在的get方法？
