Maria, if you really want to you can build the entire form in the view with
good old HTML.
1. An example set of "sentence", "meaning" and word "forms" may be
helpful - sounds like you're probably doing some sort of translation thing
or maybe it is a quiz?
2. You'll need to add <form></form> tags to what you've included in your
example; just the fields and the submit button aren't enough
3. you need to give your <select> a name attribute so you can refer to
the field later when processing the submission in the controller
- You'll want to do your naming such that you can figure out which
text each returned <select> field value is actually referring to. It
sounds
like you're going to have multiple on a page so I'd suggest naming them
with a format like <select name="text_{{=row.id}}">...</select> so that
later in your controller you can loop through all the fields submitted,
they should be in request.post_vars, and parse back out exactly what text
in the database the chosen word form goes to
4. In your sample code every single <option> is going to have value="cc"
you want <option value = "{{=cc}}"> so the value is different for each
option
5. You do not need a <br> after each <option></option> (and when you do
actually need a break use the self closing <br /> form)
6. Remember to VALIDATE the incoming data to make sure that it is
actually legitimate! If you use FORM() this is taken care of for you,
without it it is up to you to make sure that the text ID provided is
actually in the database and that the chosen word form is actually a valid
choice for that particular text.
