Weird radio button array thing!

[Anon]

Cant get my head round this one:

I have a html form which uses radio buttons. Because the form is dynamically created I use an array for the field name like this:

<input type="radio" name="LIST_BY[]" value="set">
In which there can be mulitple radio buttons

I have no problem with this method using check boxes or any other input type, but with radio buttons I get strange results either LIST_BY[0] is set or no element of the array is set at all, even if I know it should be.

I have tried using ISSET, various combinations of getenv to no avail. Any ideas??

This is (I think) because you use invalid HTML syntax, for radio you should use:

<p>Yes<br />
<input type="radio" checked name="A1" value="Yes" /></p>
<p>No<br />
<input type="radio" name="A1" value="No" /></p>

If you use multiple radio's that should correspond with each other, make them the same name.

You could use:

<?= $selected ?> name="A1"

For instance, and set $selected to "" if you don't want it selected, and $selected to "checked" if you want it selected/checked.
