基於選定字段的報告生成

Question

我目前所做的是，我使用AJAX在搜索結果的id中顯示搜索記錄的所有列，然後給出打印選項以打印這些記錄。現在我希望能夠選擇一組列（爲此，我提供了一個複選框的所有列），並只打印選定的列。我可以在php文件中獲取選定的列，但是如何從這些選定的列值中構建查詢。我的意思是可以有很多不同的組合。碼到現在爲止..

   <?php 




       echo ' <table border="1"> 
         <tr> 
         <td class="lab searchtableheader" style="color:#cd0000; padding:5px;"><input type="checkbox" name="print" value="facultyname" /><br>FACULTY</td>

         </tr>  ';?> 

JavaScript來打印：

function printDiv() 
{ 
    var divToPrint=document.getElementById('searchresults'); 
    newWin= window.open(""); 
    newWin.document.write(divToPrint.outerHTML); 
    newWin.print(); 
    newWin.close(); 
} 

Answer 1

首先您需要更改名稱= 「打印」 NAME = 「打印[]」 這樣的PHP可以拿起所有的選定的值。

無論您是使用帖子還是獲取提交信息，您都需要循環發送值。信息將在打印陣列中。

$prn = $_POST['print']; 
$sql = "SELECT "; 
$flds = ""; 
foreach($prn as $p) { 
    if($flds != "") $flds .= ","; 
    $flds .= $p 
} 
$sql .= $flds . " FROM .... 

請不代碼是未經測試，但它應該給你一個起點
