Form Servlet

[roohbir]

Hello,

I have an HTML form which has an drop down box. I want to display the
selected option from this from a Servlet. I am having problems with
this and have a feeling I am not extracting data from the drop-down
box properly. I would be really thankful if somebody can point out
what the error is. The Servlet sends the response but only 0 is
displayed while the user's choice might have been 1 or 2 or 3 or 4.

The drop down box code in html is as follows:
<td>Socks</td>
<td>4</td>
<td><select name="socks" size="1">
<option selected="selected" value="0">0</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
</select></td>
</tr>
<tr>
<td>Shirt</td>
<td>16</td>
<td><select name="shirt" size="1">
<option selected="selected" value="0">0</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
</select></td>
</tr>

The Servlet code for extraction is here:
// extract data from the drop-down buttons here
int sockQuantity =
Integer.parseInt(request.getParameter("socks"));
int shirtQuantity =
Integer.parseInt(request.getParameter("shirt"));
int trouserQuantity =
Integer.parseInt(request.getParameter("trouser"));
int jumperQuantity =
Integer.parseInt(request.getParameter("jumper"));
int shoeQuantity =
Integer.parseInt(request.getParameter("shoes"));

Thanks in advance.

Dude, lose the TAB characters. Use spaces for Usenet posts.

Hello do you not need to use request.getParameterValues() which would
return an array of values, strings.

Something like this, where getParameterValues() returns an array of
Strings.

String[] myShirts = request.getParameterValues("shirts");

then you could loop over the array and parseInt off everything.
for(int i=0;i<myShirts.length;i++){
int shirtQuantity = Integer.parseIn(myShirts;
}

I am still a bit of a newbie at this stuff myself and I did not test
this but something along these
lines should do it.

hope it helps
cheers
