Filling a text box when radio button is clicked

[KDawg44]

Hi,

I am writing a PHP website. When I am taking some input from a user,
I write some static radio buttons for a category, and then also write
some more that are generated based on a query to a database. I would
like to have a text box for a description of the category. I would
like that to be able to be typed in if the user selects on of the
static options but automatically filled in by data from the database
if they select one of the radio buttons that are DB generated. I
would also like to be able to prevent the user from changing the text
box if it is filled in with DB data (if possible, not that big of a
deal if too difficult).

Thanks.

I see how to set this with JavaScript. Can I pass the results of a
PHP query into a javascript? Something like this?

while ($row = mysql_fetch_row($rs) {
echo "<input type = radio name = radio1 value = '" . $row[0] . "'
onclick = 'fillTextBox(" . $row[0] . "," . $row[1] . ")'>";
}

and then have a JavaScript function something like:

function fillTextBox(var cat, var dbData) {
document.getElementById(cat).value = dbData;
}
THanks.

Yep, you'll need to use javascript for anything happening client-side.

And sure - it doesn't matter how the JS is generated - from a page or
echoed from PHP, for instance. The browser has no idea.
