value not being POSTED to next page

woodplease

i have a form where i post values, and then retrieve them on another page, but only one of the values is being retrieved.

This is my post form

<?php
$id = $_GET['id'];
$query = "SELECT * FROM questions WHERE quizref = " .$id ;
$question = 'questionno';
$result2 = pg_query($query) or die ("Query failed");
//let's get the number of rows in our result so we can use it in a for loop
$numofrows = pg_num_rows($result2);

?>

<form method="post" action ="editquestions.php">
<?PHP

for($i = 1; $i <= $numofrows; $i++) {
	$row = pg_fetch_array($result2); //get a row from our result set

echo '<input type="hidden" name="quizno" value="'.$id.'">
	  <input type="hidden" name="questionno" id="'.$row['questionno'].'" value="'.$row['questionno'].'" >
<br/><p>Question '.$row['questionno'].': ' .$row['question'].' <input type="Submit"  id="'.$row['questionno'].'" value="EDIT">  <br/><br/></p>

and this is the code that retrieves it

$id = $_POST['quizno'];
$question = $_POST['questionno'];

echo 'The quiz number is:'.$id;
echo'<br/>The question number is:'.$question;

It is only displaying the $id correctly,and it displays the $question as the total number of questions on the previous page, even though when you view the source, the value that is to be sent is thequestion number.

this is the link to the page that originally posts the information, and then when you click the edit button, it takes you to the page that is supposed to display that information

Oh sorry. Don't know how I manged to miss the form element.

Anyway, the code you presented here looks fine. However, looking at the html source for which you provided a link, some things are strange.
There are several inputs with name="quizno". You can have only one per form. Or, you can use name="quizno[]" to get an array containing values from all those elements.
There are no inputs with name="quizno". They have name="1", name="2" etc.

You need html along the lines of

<form action="" method="post">
	<input type="hidden" name="quizno" value="1"/>
	<input type="hidden" name="questionno" value="1"/>
	<input type="submit" value="Edit"/>
</form>
<form action="" method="post">
	<input type="hidden" name="quizno" value="1"/>
	<input type="hidden" name="questionno" value="2"/>
	<input type="submit" value="Edit"/>
</form>
<form action="" method="post">
	<input type="hidden" name="quizno" value="2"/>
	<input type="hidden" name="questionno" value="1"/>
	<input type="submit" value="Edit"/>
</form>

This way, you get the data belongning to the same form as the clicked submit button.
