[RESOLVED] radio button/form question

jadeddog

i have this simple form that posts two variables ($id and $price) to the next page (price_change_confirm.php)....i can access the $price variable on the next page, but i cannot access the $id variable.... ive done tons of these forms before, and everything looks right to me, so im sure im missing something stupid, any help would be appreciated

here is the form code:

echo "<form action='price_change_confirm.php' method='post'>\n"; 
echo "<input type='radio' name='edit_price_id' value='$id'>";
echo "<table><tr><td>$title</td>
<td>$author</td>
<td>$<input type='text' name='edit_price' value='$price'></td></tr></table>";
echo "<input type='submit' name='change_price' value='Change Price'></form>";

now on the next page i assign variables to the posted variables, and echo to test:

$new_price = $_POST['edit_price'];
$book_id = $_POST['edit_price_id'];
echo "id is $book_id and price is $$new_price";

the new price shows up but the id does not, like this "id is and price is $99.99".... i cant figure out why i can access one variable and not the other.... any help would be greatly appreciated (sorry for the newb question)

Well you posted a question and then resolved it...so what was the problem?

If you have resolved your own question in these forums then I believe it is your responsability to tell what the solution was so that in the future those that may have the same problem can see how to solve such a similar problem.

i changed how i tackled the problem completely, instead of using a radio button to select one row in the table, i put a button behind each row.... it works better that way

Houdini

and the new code that did that is what?

jadeddog

heres the actual code that i used

echo "<tr><form method='post' action='price_change_confirm.php'><input type='hidden' name='book_id' value='$id'>
<td valign='top' width='15%'>$id</td>
<td valign='top' width='40%'>$title</td>
<td valign='top' width='25%'>$author</td>
<td valign='top' width='15%'>$<input type='text' name='edit_price' value='$price'></td>
<td valign='top' width='10%'><input type='submit' name='change_price' value='Change Price'></td></form></tr>";

this way each row has its own "Change Price" button... i made the $id a hidden field as well, then i use the 'book_id' and the 'edit_price' values in the 'price_change_confirm.php' file (retrieve them through the following code:

$new_price = $_POST['edit_price'];
$book_id = $_POST['book_id'];

i like this solution better because your not limited in what you can pass through to the next file.... you can as many hidden fields as you want, and have access to all of them in the next file (that you POST to)
