PHP - Image Processing

Hello everyone, I have a datatbase containing fields id, question, answer, and type. The questions are in true/false format, multiple choice and fill in the blank(text). At the moment, I am only trying to get the true and false questions to work. My code is as follows

Code: [Select]

<?php

$connection = mysql_connect("localhost","root","root") or die("couldn't connect");
$select = mysql_select_db("login") or die ("cannot select database!");

$query = mysql_query("SELECT * FROM questions");

$numrows = mysql_num_rows($query);

if ($numrows!=0)
{
//code to login
while($row = mysql_fetch_assoc($query))
{
$dbquestion = $row['question'];
$dbanswer = $row['answer'];
$dbtype = $row['type'];
$dbid = $row['id'];
$correctanswer =  explode('|',"$dbanswer");



switch($dbtype){
case "mchoice":
echo"<br/>"; echo $dbquestion; echo"<br/>";
break;

case "boolean":
echo"<br/>"; echo $dbquestion; echo"<br/>";
echo $correctanswer[0];

//display radio buttons

?>
<form name="boolean" method="POST" action="<?php echo $_SERVER['PHP_SELF'] ?>">
True
<input name="question" type="radio" value= "True" />
False
<input name="question" type="radio" value= "False" />
<input name="id" input type="hidden" value="<?php $dbid ?>" />
<input type="submit" name="submit" id="submit" value="Submit" />

<?php
echo "The answer submitted was ";
echo  $_POST['question'];
?>

<?php
break;

case "text":
echo"<br/>"; echo $dbquestion; echo"<br/>";
//display text box
break;
}
}
}
?>

The problem I'm having is that this creates a submit button for each question. When choosing true or false for the answer and pressing submit, the answer is selected for every question. I need the code  to look at what the user has entered, check the answer against correctanswer[0].

I'm really in a bit of a hole here and if anyone can help me it would be greatly appreciated.

Many thanks in advance
James

I have an SQL table such as this:
Pairing1 Pairing2 Week 6 1 1 5 2 1 4 3 1 1 3 2 5 4 2 3 6 2 and another with teams such as:
teamid teamname 1 Teamname 1 2 Teamname 2 3 Teamname 3 The numbers in the pairing are numbers of teams, which is in another SQL table. What would be the most efficient way... of displaying the information in the form of pairngs such as
Week 1:
Team 6 vs Team 1
Team 5 vs Team 2
etc ....
What is the best way for me to sort my results?

Can you take a look at this page?  It uses php code that I have been creating.  I need it to accept the form even if checkboxes are left empty.  Currently it comes up with an error.

Here is the PHP code:

<?php

if(isset($_POST['Email_Address'])) {

   function died($error) {
      echo "Sorry, but there were error(s) found with the form you submitted. ";
      echo "These errors appear below.<br /><br />";
      echo $error."<br /><br />";
      echo "Please go back and fix these errors.<br /><br />";
      die();
   }

So I know a little about PHP but I am no expert by any means. But I have a project that I am working on for a fantasy football league and need some help. My users pick players from a list and then their selections are put into a database. So more than one user is likely to pick the same player. Then I need to score the players based off their games for the week. So I have code that gets the Distinct PlayerID and creates a form to update the player score (see code below), but I have no idea how to process the form. It's a little more complicated then the forms I've used before because the MySQL query would need to UPDATE all the rows for each individual PlayerID. Am I making any sense?

Anyway, here is the code. If anyone has suggestions on how to process this form or a better way of doing it then please let me know.

<?
print '<form id="form1" name="form1" method="post" action="update_player.php">';
// Connecting, selecting database
$link = mysql_connect('localhost','user','pass');
if (!$link) {
die('Could not connect: ' . mysql_error());
}

//Query
$query=mysql_query("select DISTINCT(PlayerID), PlayerName, Team From fantasy4.temp ORDER BY Team;") or die ('Could not connect: ' . mysql_error());
print'
<center>
<table align=center border=0 cellpadding=0 cellspacing=2 width=350>
<tr align=center>
<td width=50 align=center><b>Player ID </b></td>
<td width=50 align=center><b>Team</b></td>
<td width=200 align=center><b>Player Name</b></td>
<td width=50 align=center><b>Score</b></td>
<tr><td colspan="10" bgcolor="black" height="1"></td></tr>
';

while($row=mysql_fetch_array($query)){
if($color == 1)
{
print '<tr bgcolor=#dDdDdD>
<td align=center> ' . $row['PlayerID'] . ' </td>
<td align=center> ' . $row['Team'] . ' </td>
<td align=center> ' . $row['PlayerName'] . ' </td>
<td align=center> <input name="' . $row['PlayerID'] . '" type="text" id="' . $row['PlayerID'] . '" size="5" maxlength="5" /> </td>
</tr>';
$color=0;
}
else
{
print '<tr>
<td align=center> ' . $row['PlayerID'] . ' </td>
<td align=center> ' . $row['Team'] . ' </td>
<td align=center> ' . $row['PlayerName'] . ' </td>
<td align=center> <input name="' . $row['PlayerID'] . '" type="text" id="' . $row['PlayerID'] . '" size="5" maxlength="5" /> </td>
</tr>';
$color=1;

}
}
print '</table>';
print '<input type="submit" name="button" id="button" value="Update Player Scores" /></form>';
?>

This is what I tried that did not work

<?

// Connecting, selecting database
$link = mysql_connect('localhost','user','pass');
if (!$link) {
die('Could not connect: ' . mysql_error());
}

//Query
$query=mysql_query("select DISTINCT(PlayerID) From fantasy4.temp;") or die ('Could not connect: ' . mysql_error());


while($row=mysql_fetch_array($query)){
$PlayerID = $_POST[$row['PlayerID']];
}

while($score = array($_POST['$PlayerID'])){


//Insert Query

$query2=mysql_query("UPDATE fantasy4.temp set Score='$score' where PlayerID='$PlayerID'") or die ('Yikes could not connect: ' .mysql_error());

$result = @mysql_query($query2);
}
//Check whether the query was successful or not
if($result) {
header("location: register-success.php");
exit();
}else {
die("Query failed - " .mysql_error());
}

?>

I've read the php manual and a good few posts with similar but not identical problems and I am struggling to understand how to do this.

Ive tailored my test site to help describe the problems that  I have.

www.peterod.co.uk   

the form is the first link in the left hand bar.

Here is the code that creates the form.
<?php

// make connection
require_once "../classes/sqlconselfbuild.php";

$query = mysql_query("SELECT * FROM `materials` ORDER BY `id` ASC"); 

?>
<form action="../engines/testengine1.php" method="post">

<?php
// results
while ($row = mysql_fetch_array($query)):
    $id = $row['id'];
?>
<p>
    id number: <input type="text" name="materials[<?php echo $id; ?>][name]" value="<?php echo $row['id']; ?>" />
    Material:  <input type="text" name="materials[<?php echo $id; ?>][material]" value="<?php echo $row['material']; ?>" />
    Stage:    <input type="text" name="materials[<?php echo $id; ?>]    [stage]" value="<?php echo $row['stage']; ?>" />
    Qantity:  <input type="text" name="materials[<?php echo $id; ?>][quantity]" value="<?php echo $row['quantity']; ?>" />
    Unit:    <input type="text" name="materials[<?php echo $id; ?>][unit]" value="<?php echo $row['unit']; ?>" />
    
    <br />
</p>
<?php endwhile; ?>
<input type="submit" name="submit" value="Submit" />
</form>







I am unsure how to get this information to insert into the database.  How do you use the UPDATE query with a loop generated form
?
