MySQL和PHP的日期范围

Question

尝试获取特定日期范围内的表格时，似乎出现问题。 这是我的PHP代码。 我尝试使用BETWEEN和<=来获取日期范围，但它似乎不起作用。 当我将结果打印到控制台时，我只是得到一个Uncaught SyntaxError：意外的数字。 有什么建议么？

if($_POST['subdate'] != "")
    {

        $sdate = dateClean($_POST['subdate']);
        $edate = dateClean($_POST['subdateend']);
        if($checkWhereVar==0)
        {

            if($_POST['subdateend'] != "")
            {

                $longQuery.= "SubmissionDate >= '".$sdate."' AND SubmissionDate <= '".$edate."";
                echo ("<script>console.log('$longQuery')</script>");
            }
            else{

                $date = date('Y/m/d H:i:s');
                $edate = $date;
                $longQuery.= "SubmissionDate >= '".$sdate."' AND SubmissionDate <= '".$edate."";

            }

            //$longQuery.= " SubmissionDate BETWEEN = '".$sdate."'";
            $checkWhereVar = 1;
        }
        else
        {
             $date = date('Y/m/d H:i:s');
             $edate = $date;
            echo ("<script>console.log('in sub date else')</script>");
            $longQuery.= "SubmissionDate >= '".$sdate."' AND SubmissionDate <= '".$edate."";
        }
        $filter .= " Submission Date: <i>".$_POST['subdate']."</i>";
    }

Answer 1

如果不看脚本的其余部分，就很难诊断出来，但是似乎您的字符串连接可能是导致这种情况的因素：

$longQuery.= "SubmissionDate >= '".$sdate."' AND SubmissionDate <= '".$edate."";

只需在开头添加一个空格，如下所示：

$longQuery.= " SubmissionDate >= '".$sdate."' AND SubmissionDate <= '".$edate."";

另外，您似乎在字符串末尾缺少单引号。 因此，只需执行以下操作：

$longQuery.= " SubmissionDate >= '$sdate' AND SubmissionDate <= '$edate'";

使用双引号时，可以进行字符串替换，因此不必将这些行与串联. 显示每个字符串的位置。

就是说，这是我用上面提到的内容的每个实例来清理您的代码。

if($_POST['subdate'] != "")
    {

        $sdate = dateClean($_POST['subdate']);
        $edate = dateClean($_POST['subdateend']);
        if($checkWhereVar==0)
        {

            if($_POST['subdateend'] != "")
            {

                $longQuery.= " SubmissionDate >= '$sdate' AND SubmissionDate <= '$edate'";
                echo ("<script>console.log('$longQuery')</script>");
            }
            else{

                $date = date('Y/m/d H:i:s');
                $edate = $date;
                $longQuery.= " SubmissionDate >= '$sdate' AND SubmissionDate <= '$edate'";

            }

            //$longQuery.= " SubmissionDate BETWEEN = '$sdate'";
            $checkWhereVar = 1;
        }
        else
        {
             $date = date('Y/m/d H:i:s');
             $edate = $date;
            echo ("<script>console.log('in sub date else')</script>");
            $longQuery.= " SubmissionDate >= '$sdate' AND SubmissionDate <= '$edate'";
        }
        $filter .= " Submission Date: <i>".$_POST['subdate']."</i>";
    }
