Question

I have a question which might sound a bit confusing but i’ll try my best to explain my problem.

I have 2 tables in my sql database: Table 1 is called Events, Table2 is called Results

The Events table contains entries about a past computer game match

eg. EventID   EventName  EventDate  Location 
      1       GG vs AU    04/08     Game room 1

The Results table contains nearly the same entries.. but with more detail for that single entry

eg.  EventID   MemberID       Score        Ranking 
       1         02        7(victory):5      1st

Basically, I will go into the “Events” php file, and I will see the entries.
When I press any of the entries in the same row, (eg. 1, GGvsAU, 04/08, Gameroom1), itll link me to the Results Table which will give me a bit more indepth information about that match.
from that example, the eventID is 1 so when I press any of the entries in the same row, itll link me to results.php?EventID=1

The Events php file is working perfectly so its all good.. but once I press the entry, it links me to the Results php file.

What I have trouble right now is with the Results php file. When I press the entry in Events.php, it links me to results.php?EventID=1, but it shows me all the entries inside the database.. I want only the info for EventID1..

Also, would it be possible to “HIDE” the EventID and the “MemberID from view based on my codes below?

Events.php

<?
        $pdo = new PDO('mysql:host=localhost;dbname=clubresults', 'root', '12345678');
    #Set Error Mode to ERRMODE_EXCEPTION.
    $pdo->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);  

$query = $pdo->query('SELECT EventID, EventName, EventDate, Location from events');
$rowset = array();

if ($query) {
  while ($row = $query->fetch(PDO::FETCH_ASSOC)) {
    // Build array of rows
    $rowset[] = $row;
  }    

  // Output header first
  $headrow = $rowset[0];
  print("<table border=\"1\">\n<tr>\n");
  // Use $rowset[0] to write the table heading
  foreach ($headrow as $col => $val) {
    printf("<th>%s</th>\n", $col);
  }
  print("</tr>");

  // Then output table rows.
  // Outer loop iterates over row
  foreach ($rowset as $row) {
     print("<tr>");
     // Inner loop iterates over columns using $col => $val
     foreach ($row as $col => $val) {
        // We don't know your column names, but substitute the first column (the ID) for FIRSTCOL here
        printf("<td><a href=\"listresults.php?EventID=%s\">%s</a></td>\n", $row['EventID'],$val);
     }
     print("</tr>");
  }
}
print("</table>");
?>

Results.php (the one I have problem with)

   <?
 #Get the event id from $_GET
    $int_event_id = $_GET["EventID"];
    if((int)$int_event_id)
    {
        $pdo = new PDO('mysql:host=localhost;dbname=clubresults', 'root', '12345678');
    #Set Error Mode to ERRMODE_EXCEPTION.
    $pdo->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);  
  $query = $pdo->query('SELECT * from results WHERE EventID ='$int_event_id' ORDER By EventID ASC');
}
    $rowset = array();

if ($query) {
  while ($row = $query->fetch(PDO::FETCH_ASSOC)) {
    // Build array of rows
    $rowset[] = $row;
  }    

  // Output header first
  $headrow = $rowset[0];
  print("<table border=\"1\">\n<tr>\n");
  // Use $rowset[0] to write the table heading
  foreach ($headrow as $col => $val) {
    printf("<th>%s</th>\n", $col);
  }
  print("</tr>");

  // Then output table rows.
  // Outer loop iterates over row
  foreach ($rowset as $row) {
     print("<tr>");
     // Inner loop iterates over columns using $col => $val
     foreach ($row as $col => $val) {
        // We don't know your column names, but substitute the first column (the ID) for FIRSTCOL here
        printf("<td><a href=\"index.php?ID=%s\">%s</a></td>\n", $row['EventID'],$val);
     }
     print("</tr>");
  }
}
print("</table>");

I really appreciate anyone who can help me with this problem!
Thanks very much!

Here you go. In your “Results.php”, you need to add a where clause to your query to display the data for the particular event id only. So check my below code.

<?
    #Get the event id from $_GET
    $int_event_id = $_GET[“EventID”];
    if((int)$int_event_id)
    {
       $pdo = new PDO(‘mysql:host=localhost;dbname=clubresults’, ‘root’, ‘12345678’);
       #Set Error Mode to ERRMODE_EXCEPTION.
       $pdo->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);  

   $query = $pdo->query("SELECT * from results WHERE EventID ='$int_event_id' ORDER By EventID ASC");
}

?>

Also you are linking with “listresults.php” in “events.php”, not sure if its a typo. It should be linked to “Results.php” right?
