動態表中有多個搜索條件PHP結果

Question

希望有人可以提供幫助，這對我來說是個新手，可以教自己更多的娛樂性，但是我似乎無法使此頁面正常工作。 我以前使用過一個搜索過濾器，但是當我添加更多過濾器時，它似乎根本沒有過濾。 如果未添加任何搜索，嘗試使頁面顯示所有記錄，則用戶可以搜索1個或多個過濾器，並且將顯示相關記錄。 3個過濾器是一個日期范圍，每個范圍都包含來回文本字段...

我的代碼如下。

    <?php require_once('Connections/tidentchase.php'); ?>

    if (PHP_VERSION < 6) {
    $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
    }
    $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);

    switch ($theType) {
    case "text":

我完全錯了，或者我接近了。

在處理輸入字段時，需要構建sql語句。 代替這個：

$newdatefrom_Recordset1 = "-1";
if (isset($_GET['newdatefrom'])) 
{
    $newdatefrom_Recordset1 = $_GET['newdatefrom'];
}

您將需要執行以下操作：

$fld = ""; $whr = ""; // initialise variables
$newdatefrom_Recordset1 = "";
if (isset($_GET['newdatefrom'])) {
  if ( $fld != '' ) $fld .= ",";     //--- build field list 
  if ( $whr != '' ) $whr .= " or ";  //--- build sql where joiner
  $fld .= 'dateopen';
  $whr .= "dateopen='".$_GET['newdatefrom']."'";
}
//--- repeat for each field you want to search on
//--- apply any rules i.e. date range and values etc
//--- when ready to run query then
$qry = "SELECT ".$fld." WHERE ".$whr;
