Populate dropdown list w/values checked in checkboxes

[dmears1]

I need to be able to populate a dropdown list with values that are selected (checked) in checkboxes.

<input type="checkbox" name="usergroup[]" value="<?=$usergroup_name?>">

Each checkbox value is placed in an array (usergroup[]). Is there a way to get the values of checked boxes without submitting the form?

Yes. You can use "getElementsByName" to effectively return an array of controls, and then loop through them.

However, you might run into problems because of your illegal naming syntax ("[" and "]" are NOT legal characters for HTML names, so you might want to change them).

Hope this helps,

Altrhough this is bordering on Javascript rather than plain html. To overcome the bracket problme in elemtn names. )I'm assuming you have PHP somewhere in there) you can use getElementsByID instead. and give each elemtn an ID without the brackets.

BTW, the javascript forum is here: Forum216

Actually, they are valid, as we have discovered at the end of this particular thread: thread434-1221256

They are vital for multiple selections in PHP as well, so one will see them used quite frequently alongside PHP.

Thanks for all the help. I've made some headway, but it's still not working as I'd wish. However, I think I should post this in the javascript forum for help there. Thank again!

Vragabond,

Thanks for pointing that out - I made the same mistake as Lee did.

I've learned something new today!
