How do I extract multiple selectd values from the request object? 1

[nybz]

I have set up a <select> with multiple options enabled. Once submitted how do I retrieve the values? Do they come in as an array or comma delimited string or what?

hi manarth - i am sending it to a java servlet. thank you for your interest.

Ok, handle it with the doGet or doPost respomse, as matches the form.

Multiple select boxes are passed as arrays:

 String [] selections = req.getParameterValues("selectionoptions");

Don't forget, your user may not select anything, so test for null before trying to load the array

Here's a good web forms and servlets tutorial.

How would you handle this with PHP? I have this code:

<p><font face="Verdana"><small>Question 5 :</small><br>
<small><select name="champ5[]" size="2" multiple>
<option selected value="0">Choose</option>
<option value="Reponse5_1">1</option>
<option value="Reponse5_2">2</option>
<option value="Reponse5_3">3</option>
<option value="Reponse5_4">4</option>
<option value="Reponse5_5">5</option>
</select></small></font></p>

I know it's comma delimited when it comes back but how do I reference the string? I've tried $champ5 and that's not it???

Thanks in advance.

Your problem lies in the html: your select statement - <select name="champ5[]" size="2" multiple>.

You don't need to declare in the html that this represents an array.

<p><font face="Verdana"><small>Question 5 :</small><br>
        <small><select [COLOR=red]name="champ5"[/color] size="2" multiple>
         <option selected value="0">Choose</option>
         <option value="Reponse5_1">1</option>
         <option value="Reponse5_2">2</option>
         <option value="Reponse5_3">3</option>
         <option value="Reponse5_4">4</option>
         <option value="Reponse5_5">5</option>
        </select></small></font></p>

Your array name from this code will be $champ: $champ[0] represents the first chosen item; etc.
