How to get textbox value that are inside of while loop?

Question

I have textbox that are query from database. I show this textbox from while loop.

$ans_no = 0;
 while($ed_ans_row = mysql_fetch_array($ed_ans_query)) {
   $edit_answer = $ed_ans_row['name'];
   $edit_id = $ed_ans_row['id'];
   echo "<input type=\"text\" name=\"ans[]\" class=\"ans\" value=\"$edit_answer\" /><br/>";
   echo "<input type=\"hidden\" name=\"edit_id[]\" class=\"ans\" value=\"$edit_id\" />";
  }

Now, I want to save this pair of answer and id into database like this:

UPDATE table SET answer='ans[0]' WHERE id='edit_id[0]';

But I don't know how many textbox are query from database. And how to update this answer and id together correctly.

I don't have a lot of experience in php. Thanks for every reply.

how about name=\"ans-".$edit_id."\". it will be easier later on when trying to save. — bansi

Create your text box with names name[]

<input type='text' name='name[]'>

Get values like that :-

$name= $_POST['name'];
$N = count($name);
for($i=0; $i < $N; $i++)
{
echo($name[$i]);
}

You can say:

$i = 0;
$answers = array();
while(isset($_POST['ans-'+$i])){
    $answers[$i] = $_POST['ans-'+$i];
    $i++;
}
print_r($answers);
