Eval() Help

[BulldogGC]

I'm not even sure if it's the correct tag I want to be using.
Anyway ...

I have a form that is dynamically generated ...
Say I choose to have 3 answers it will generate 3 input text fields named "form_answer1" through "form_answer3"

And what I want to do is insert this into a database.
But I can't get it to work ... here's the code I'm trying:

$i = 0;
	while($i < $count) {
		$answer_content = eval("form_answer" &  $i);
			$sql_insert = "INSERT INTO polla (pollid,answer) VALUES ('$pid','$answer_content')";
			$execute_insert = mysql_query($sql_insert);
				$i++;
	}

Basically I'm trying to dynamically generate whatever was inputted into the "form_answerWHATEVERNUMBER"

Well, I'm not sure, but here are some ideas--

instead of this:

$answer_content = eval("form_answer" &  $i);

try this:

$answer_content = "form_answer" . $i;

See, because for what you are doing, you don't really need to use eval for this type of thing. I hope that helps your problem!

NEW:

$i = 0;
    while($i < $count) {
        $answer_content = "form_answer" . $i;
            $sql_insert = "INSERT INTO polla (pollid,answer) VALUES ('$pid','$answer_content')";
            $execute_insert = mysql_query($sql_insert);
                $i++;
    }

OLD:

$i = 0;
    while($i < $count) {
        $answer_content = eval("form_answer" &  $i);
            $sql_insert = "INSERT INTO polla (pollid,answer) VALUES ('$pid','$answer_content')";
            $execute_insert = mysql_query($sql_insert);
                $i++;
    }

				for ($i = 1; $i <= $count; $i++) {
					$answer_content = 'form_answer' . $i;
						$sql_insert = "INSERT INTO polla (pollid,answer) VALUES ('$id','{$_POST[$answer_content]}')";
						$execute_insert = mysql_query($sql_insert);
				}

Final code.

Did that final code work for what you were doing?
