设置php变量等于“while（$ row = mysql_fetch_array”

生成的表格单元格的值我有一个基于选择框从mysql数据库中提取数据的php页面，这可以通过单独的php页面处理那么MySQL的查询。使用JavaScript原来的页面上显示这样的结果不必每次都让人耳目一新。

每个下拉列表中有5个MySQL字段单行返回从MySQL查询。

我需要根据选择的选项执行一些逻辑，因此需要将每个返回的mysql字段值存储为一个唯一的变量，我可以在下一页中引用它。

如何使用$ _POST方法设置此变量而不需要引用ID？还有另外一种方法吗？

我的两个页面的代码显示在下面，如果任何人都可以指向正确的方向，我将不胜感激。

的index.php

<html> 
<head> 
<script type="text/javascript"> 
    function showUser(userNumber, str) 
    { 
    document.getElementById("r"+(userNumber+1)).style.display="block"; 
    if (str=="") 
    { 
     document.getElementById("txtHint" + userNumber).innerHTML=""; 
     return; 
    } 
    if (window.XMLHttpRequest) 
    {// code for IE7+, Firefox, Chrome, Opera, Safari 
     xmlhttp=new XMLHttpRequest(); 
    } 
    else 
    {// code for IE6, IE5 
     xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); 
    } 

    xmlhttp.onreadystatechange=function() 
    { 
     if (xmlhttp.readyState==4 && xmlhttp.status==200) 
     { 
     document.getElementById("txtHint" + userNumber).innerHTML=xmlhttp.responseText; 
     } 
    } 
    xmlhttp.open("GET","getdata1.php?q="+str,true); 
    xmlhttp.send(); 
    } 
</script>

构建您想要使用的值的隐藏输入是行之有效的方法。 – 2012-01-21 15:11:19

我会给你希望在页面是否与工作的每个值<input type='hidden' value='xxxx'>领域，并更新这些以及通过JavaScript表格单元格。然后，您将在$ _POST数据中使用这些值。
