[SOLVED] Using GET isnt working.

[Eggzorcist]

Alright, heres my JS code. All works but one thing. It seems like my PHP code isn't receiving any GET information but I'm having trouble seeing how it isnt.

 

 

// JavaScript Document

var xmlhttp;

function showUser(str)
{
xmlhttp=GetXmlHttpObject();
if (xmlhttp==null)
  {
  alert ("Browser does not support HTTP Request");
  return;
  }
var url="trackeractions.php";
url=url+"?id="+str;
//url=url+"&sid="+Math.random();
xmlhttp.onreadystatechange=stateChanged;
xmlhttp.open("GET",url,true);
xmlhttp.send(null);
}

function stateChanged()
{
if (xmlhttp.readyState==4)
{
document.getElementById("txtHint").innerHTML=xmlhttp.responseText;
}
}

function GetXmlHttpObject()
{
if (window.XMLHttpRequest)
  {
  // code for IE7+, Firefox, Chrome, Opera, Safari
  return new XMLHttpRequest();
  }
if (window.ActiveXObject)
  {
  // code for IE6, IE5
  return new ActiveXObject("Microsoft.XMLHTTP");
  }
return null;
}

 

 

 

I'm not that good in AJAX. This is for my media design class.

 

 

Thanks

Are you calling it from a form or what?

[Eggzorcist]

Well I want to be able to retrieve the GET in my php, I've tested the PHP and it works, but it cannot retrieve the $_GET['id']; So I'm guessing its the javascript that isn't producing a $_GET well. What can I do?

[Ken2k7]

Can you post the PHP script trackeractions.php as well?

[alco19357]

Does the internet browser you're using support ajax like you asked in the code? I know it's a silly question, but typically that is the problem.

[Eggzorcist]

here's the PHP code.

 

<?php
$dbhost = "localhost";
$dbuser = "root";
$dbpass = "";
$dbname = "tgj4u";


mysql_connect($dbhost, $dbuser, $dbpass);
mysql_select_db($dbname) or die(mysql_error());
$id =  $_GET['id'];
$id = mysql_real_escape_string($id);
$query = "SELECT * FROM maildata WHERE id = '$id'";
$qry_result = mysql_query($query);



if (mysql_num_rows($qry_result)){


while($info = mysql_fetch_assoc($qry_result)){

echo "Sent by: " . $info['sender'] . "<br>";	
echo "Recipient: " . $info['recipient'] . "<br>";	
echo "Departed: " . $info['depart'] . "<br>";
echo "Satus: " . $info['depart'] . "<br>";
echo "Current Location: " . $info['currentlocation'] . "<br>";
echo "Arrival Location: " . $info['finallocation'] . "<br>";
echo "Expected on: " . $info['expected'] . "<br>";

}
}

else
{
   echo "<p>No data was found with that ID.</p>\n";
}





?>

 

I've tried with both mizila firefox and internet explorer.

I would like to also add that, if I go to the php page on its own and add /trackeractions.php?id=55583 a correct id to the URL it works.

[Eggzorcist]

Does anyone have an alternate script which does the same thing?

[Stooney]

What is the end URL that's generated before the request?

 

If you don't know then after this line:

url=url+"?id="+str;

add this:

alert(url);

[Eggzorcist]

I did alert(url) and it seem slike its not passing to the get becuase it's not alerting whatsoever... However, it is getting data from "trackeractions.php";

 

its a little strange

[Eggzorcist]

ah here is there error:

 

<form>
Package ID:<input name="id" type="text" id='id' value="f" size="10" maxlength="10" /> 
<br />
<input type='button' onclick='showUser(this.value)' value="Track"/>
</form><br />

 

What is being tracker is the wrong value. I want it to pickup the value to value="f" but what it is picking up now is value="track" which is the button value, what is the command to change it to the text box?

[jacksonmj]

onclick="showUser(document.getElementById('id').value)"
