Problems pulling data from table

hellcat1 · #1 01-Aug-2004, 08:55

I'm a little baffled as to why my PHP is not pulling all my data it should from MySQL. Here is my situation.

PHP Code:


$connection2 = mysql_connect("localhost", "hellcat1", "**********") or die ('I cannot connect to the database because: ' . mysql_error()); 
mysql_select_db("automaint", $connection2);

echo "username = ".$username."<br>";
$result2 = mysql_query("SELECT * FROM automaint.vehicles WHERE username='$username'");
$myrow2 = mysql_fetch_array($result2);
echo "result2 = <br>";
print_r($myrow2);
echo "<br>";

Here is what table automaint.vehicles contains

id username vehicle
1 hellcat1 2001 Chevrolet S10
2 hellcat1 2001 Dodge Ram 1500
3 hellcat1 1985 Chevrolet S10 Blazer
4 hellcat1 1987 GMC S15

Here is the results

username = hellcat1
result2 =
Array ( [0] => 1 [id] => 1 [1] => hellcat1 [username] => hellcat1 [2] => 2001 Chevrolet S10 [vehicle] => 2001 Chevrolet S10 )

Any ideas why it's only pulling the first row and stopping?

You need to loop through the results/resource ($result2)...

PHP Code:


// snipped php code...
while( $myrow2 = mysql_fetch_array($result2) )
{
  echo "result2 = <br>";
  print_r($myrow2);
  echo "<br>";
}
// snipped php code...

  print_r($myrow2);
  echo "<br>";
}

Great, I changed the code to

PHP Code:


$result2 = mysql_query("SELECT * FROM automaint.vehicles WHERE username='$username'");
$vehicleoptions = "<select name=\"vehicles\">";
while( $myrow2 = mysql_fetch_array($result2) ) 
{ 
  $vehicleoptions .= "<option value=\"".$myrow2[vehicle]."\">".$myrow2[vehicle]."</option>";
}
$vehicleoptions .= "</select>";
echo "<br>";

And now I'm dynamically building a select box for entering data.

Aha, I see what you're doing there. All set to go?

For that issue yes. Now I'm trying to figure the best way to display the data stored in automaint.oil for a user with multiple vehicles (as seen in the above select box).

Ideally, I would like to display each vehicles of $username in automaint.vehicles in it's own table with all instances from automaint.oil listed like this.

If you're looking to put the data into table format, you can use echo statements within the while loop (after executing the query) to generate the table.

I've already got it up and working.
