pagination and forms submit

[x_maras]

Hi,

I'm writing a questionnaire and I ve got different questions in different pages.

For changing pages I use this.

 

$nextpage = $currentpage + 1;
echo "<a href='questionnaire.php?currentpage=". $nextpage ."' class='next'>
		<input type='submit' name='nextbutton' value='next >>' />
	 </a>";

 

I thought to make the link to the next page a submit button in order to submit the form also and to save the values in an array and then the array in a session.

 

The questions are being loaded from a database so there is not specific number of questions or question types in every page.

 

The thing is that when I press the button next I can't even do this:

if(isset($_POST['nextbutton'])){
     echo "something";
}

 

and here is a bigger part of the code:

 

if($currentpage <= $arraycheck){
	//selects one record from the specific position
	$sqlPresentCategories = "SELECT * FROM categories WHERE enquete_id=". $enquete ." LIMIT ". $arrayPosition[$currentpage] .", 1";
	$resultPresentCategories = mysql_query($sqlPresentCategories);
	while($categoryShow = mysql_fetch_array($resultPresentCategories)){
		echo  $categoryShow['category'] ."<br />";
		$questionNumber = 1;//used for numering the questions as they are presented in the page
		$sqlQuestions = "SELECT * FROM questions WHERE cat_id=". $categoryShow['id'] ." AND visibility='on'";
		$resQuestions = mysql_query($sqlQuestions);
		echo "	<form method='POST'>";
		//fetching the questions which have the visibility turned on
		while($questionCheck = mysql_fetch_array($resQuestions)){
			$paramQuestionId = $questionCheck['id'];
			$paramQuestionText = $questionCheck['text'];
			$switchVar = $questionCheck['type_id'];
			//3 types of questions and 3 types of checks
			switch($switchVar){
				case 1: 
					normalQuestions($paramQuestionId, $questionNumber);	
					break;
				case 2: 
					radioImagesQuestions($paramQuestionId, $paramQuestionText, $questionNumber);
					break;
				case 3: 
					checkboxQuestions($paramQuestionId, $paramQuestionText, $questionNumber);
					break;
				default:
					echo "Error! All the questions should have a type";
			}
			$questionNumber++;
		}
		if($currentpage <= $arraycheck){
			// get next page
			$nextpage = $currentpage + 1;
			// echo forward link for next page 
			echo "<a href='questionnaire.php?currentpage=". $nextpage ."' class='next'>
					<input type='submit' name='nextbutton' value='next >>' />
				  </a>";
		}
		echo "	</form>";
		if(isset($_POST['nextbutton'])){
			echo "something";
		}
	}
}
