Anyone knows what I'm doing wrong here? I am getting supplied argument is not a valid MySQL result resource in line 34

<?php
//Connect to database server
$conn=mysql_connect("mywebsite", "user", "pass");
if (!$conn)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("data", $conn);

?>

Your query is failing. Try placing this after your query call

if (!$result) {
    die('Invalid query: ' . mysql_error());
}

Not necessarily the problem but this code

if (!$conn)
{
  die('Could not connect: ' . mysql_error());
}

Should be moved to line 4.

Interesting because I don't see anywhere in your code where you're querying a 'data' table. If it couldn't find the database it would give you Unknown database 'data' not Table 'data' doesn't exist .

Is that all of the code or is that just a bit of it? Also, repost your code with the changes.

well yeah, the fact that you left out that it said data.Student is pretty big :) lowercase Student on line 32 , case is important, that should fix it

It says "Invalid query: Table 'data' doesn't exist"
Is that mean it can't find my databasE?

Tonkz 0 Light Poster · Answer 2 · 2009-05-06T23:16:48+00:00

I updated the post, the same result as before "Invalid query: Table 'data' doesn't exist

Tonkz 0 Light Poster · Answer 3 · 2009-05-06T23:28:59+00:00

This code is all of it I didnt change anything besides user, pass, data, and website.
I have rechecked my codes but I can't seem to find what I did wrong.

<?php
//Connect to database server
$conn=mysql_connect("website", "user", "pass");
if (!$conn)
  {
  die('Could not connect: ' . mysql_error());
  }
mysql_select_db("data", $conn);

K, last addition, if this doesn't give us something then I'm fresh out of ideas. replace mysql_select_db() with

$dbselect = mysql_select_db('data', $conn);
if(!$dbselect) {
  die('Couldn\'t use database: ' . mysql_error());
}

Tonkz 0 Light Poster · Answer 5 · 2009-05-06T23:46:28+00:00

Still the same thing "Invalid query: Table 'data.Student' doesn't exist"
well I left out ".Student" before see if that helps

<?php
//Connect to database server
$conn=mysql_connect("website", "user", "pass");
if (!$conn)
  {
  die('Could not connect: ' . mysql_error());
  }
$dbselect = mysql_select_db('data', $conn);
if(!$dbselect) {
 die('Could not find data: ' . mysql_error());
}

One silly question how do you repeat the table ("<td></td>") as long as the statement is true because my other data wasn't inside the table

<?php
//Connect to database server
$conn=mysql_connect("website", "user", "password");
if (!$conn)
  {
  die('Could not connect: ' . mysql_error());
  }
$dbselect = mysql_select_db('data', $conn);
if(!$dbselect) {
 die('Could not find data: ' . mysql_error());
}

?>

	     	 faculty.First_Name AS afirst,

             faculty.Office AS office,
	     	 faculty.Phone AS phone
      FROM student
	  INNER JOIN faculty
	  ON student.Advisor_ID=faculty.Faculty_ID
      ORDER BY last, first, afirst, alast, office, phone;");
	  

      if (!$result) {

      die('Invalid query: ' . mysql_error());

      }
	  	  
while ($row = mysql_fetch_array($result)) {

move the echo '</table>'; outside the loop. or just put </table> before </body> and remove the echo altogether
