PHP AJAX POST发送多个变量 [英] PHP AJAX POST send multiple variables

问题描述

与阿贾克斯后到PHP我可以发送多个变量，如果是什么语法？

<$p$p><$c$c>loadXMLDoc("scripts/product_transfer.php?group="+group+"subgroup="+subgroup+"user="+user+,function()

这样的事情??

下面是函数code：

<$p$p><$c$c>//--------------------------------------------------------------------------------------------------- -------------------------------------------------- --------------------- //函数来处理Ajax 函数loadXMLDoc（URL，cfunc） { 如果（window.XMLHtt prequest）   {// $ C $下IE7 +，火狐，Chrome，歌剧，Safari浏览器   XMLHTTP =新XMLHtt prequest（）;   } 其他   {// code对IE6，IE5   XMLHTTP =新的ActiveXObject（Microsoft.XMLHTTP）;   } xmlhttp.onreadystatechange = cfunc; xmlhttp.open（POST，网址，真实）; xmlhttp.send（）; }

解决方案

是的，你可以，但你忘记了＆安培; 值之间秒。您也可以使用POST方法，参数发送（）方法发送数据。另外不要忘了使用连接codeURIComponent（）的字符串值：

  xmlhttp.open（POST，网址，真实）;
xmlhttp.send（组=EN + codeURIComponent（组）+
              ＆放大器;亚组=EN + codeURIComponent（分组）+
              ＆放大器;用户=EN + codeURIComponent（用户））;
 

with an ajax post to php can i send multiple variables, and if so whats the syntax?

loadXMLDoc("scripts/product_transfer.php?group="+group+"subgroup="+subgroup+"user="+user+,function()

something like that??

here is the function code:

//---------------------------------------------------------------------------------------------------    -----------------------------------------------------------------------
//Function to handle ajax
function loadXMLDoc(url,cfunc)
{
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=cfunc;
xmlhttp.open("POST",url,true);
xmlhttp.send();
}

解决方案

Yes you can but you have forgotten the &s between values. You can also send data with POST method as argument to send() method. Also don't forget to use encodeURIComponent() on string values:

xmlhttp.open( "POST", url, true );
xmlhttp.send( "group="+encodeURIComponent(group)+
              "&subgroup="+encodeURIComponent(subgroup)+
              "&user="+encodeURIComponent(user) );
