如何识别 PDOStatement::execute() 中的无效参数错误

Question

我知道堆栈中有一些通用的答案（我已经阅读了它们），但我无法理解我在下面的代码片段中做错了什么。 我已经记录了所有变量值并且它们是正确的，但我仍然收到错误。 我在过去几个小时里一直在看这段代码，但失败了。 代码片段是：

   global $connPDO;
    $userId = $_COOKIE["userID"];
    $currentDateTime = date("Y-m-d H:i:s");

    $sql  = "UPDATE project_progress SET
                      project_part_no             = :project_part_no           ,
                      progress_description        = :progress_description      ,
                      progress_update_datetime    = :progress_update_datetime  ,
                      cad                         = :cad                       ,
                      blds                        = :blds                      ,
                      p_floor                     = :p_floor                   ,

                      progress_update_by_id       = :progress_update_by_id
            WHERE project_progress_id             = :project_progress_id        ";

    $queryInsert = $connPDO->prepare($sql);

    $binds = array(
        ':project_progress_id'                   =>      $_POST["recordId"],
        ':project_part_no'                       =>      $_POST["projectPartNo"],

        ':f_floor'                               =>      $_POST["fFloor"],
        ':bridges'                               =>      $_POST["bridges"],
        ':tracks'                                =>      $_POST["tracks"],
        ':p_veg'                                 =>      $_POST["pVeg"],
        ':f_veg'                                 =>      $_POST["fVeg"],
        ':obj_model'                             =>      $_POST["objModel"],
        ':obj_place'                             =>      $_POST["objPlace"],
        ':spw'                                   =>      $_POST["spw"],
        ':fence'                                 =>      $_POST["fence"],

        ':progress_update_by_id   '              =>      $userId
    );

    //echo $binds;
    $querySuccess = $queryInsert->execute($binds);

    echo $querySuccess;

错误是：

Answer 1

$binds最后一个参数的$binds ...

':progress_update_by_id   '

最后有一些额外的空格。 删除这些空格...

':progress_update_by_id'
