PHP中的文件创建从javascript获取内容

Question

I am trying to make a website where the user is supposed to enter a short text in a textarea aswell as entering their e-mail and a personal id. I am trying to send this through javascript in one variable. Problem is when Irun the code no file is created. Here is the code I am using.

    function load(){
       var xmlhttp;
       if(window.XMLHttpRequest){
              xmlHttp= new XMLHttpRequest();
           }else{
       xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
}


    var textToSend=document.forms["form"].id.value + " "+document.forms["form"].mail.value+" "+document.forms["form"

xmlhttp.open("GET","serverside.php?txt="+textToSend,"true");
xmlhttp.send();
   }



    <?php
    $txt=$_GET["txt"];
    $spacing="\n \n";

    $my_file = 'userdata.txt';
    $handle = fopen($my_file, 'a') or die('Cannot open file: '.$my_file);
    fwrite($handle, $txt);
    fclose($handle);

    ?>

Answer 1

I cannot guarantee any of these will fix the problem, but you should try them:
1) using POST instead of GET
2) instead of $my_file='userdata.txt' try $my_file='./userdata.txt'
3) having w instead of a in fopen

Answer 2

The fopen function does not create files by default -- it fails with "No such file or directory" error. You say that "no file is created", so I believe you didn't create the userdata.txt file manually.

Create empty userdata.txt file and see if that helps.
