Question

I have a INSERT operation in my website which works like this.

1. On index.html file when a button is pressed a javascript function is called.
2. In the javascript function AJAX is used to send the request to the php file with necessary parameters
3. The php file accesses the database inserts data.

For your reference here is the code for the above tasks.

2.Javascript function

function grandFinale()
{
        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").innerHTML=xmlhttp.responseText;
    }
  }
xmlhttp.open("GET","insert.php?q=&name=" + encodeURIComponent(document.getElementById('name').value) + "&txtScore1=" + encodeURIComponent(document.getElementById('txtScore1').innerHTML),true);
xmlhttp.send();
document.location.reload();

}

1.HTML button

<p id="txtScore1" align="center" style="color: #cc6699; font-size: 18px; "></p>
<label class="control-label" for="input01">Name</label>
<a href="#" class="btn btn-primary" onclick="javascript:grandFinale()" >Submit My Score</a>

3.PHP Script

<?php
    $con = mysql_connect("host","uname","pword");
    if (!$con)
      {
      die('Could not connect: ' . mysql_error());
      }

    mysql_select_db("dbname", $con) or die( "Unable to select database");

    $sql="INSERT INTO 'masterTable' ('Name', 'Score') VALUES ('{$_GET['name']}','{$_GET['txtScore1']}')";

    if (!mysql_query($sql,$con))
      {
      die('Error: ' . mysql_error());
      }
    echo "1 record added";

    mysql_close($con);
    ?>

Things work fine when I try locally on harddisk but after I host it on 000webhost.com the INSERT doesnt work. Can you suggest where I went wrong?

Answer 1

I would first check to see if the user you have set up for the database (uname) on 000webhost.com has INSERT privileges.
