Well lest go trough the basic steps then (but I still recomend you to visist the
www.w3.org
and realy spend some time trying to understand the specifications - it will save you
lots
of headache in the future...):
First you start with the FORM tag:
<form method=POST action=start.asp>
Here we see two attributes METHOD and ACTION.
METHOD should be POST in our case, and the ACTION is a pointer to a page that should
be handling the FORM request. In this case that page is called START.ASP, in your
case it should probably be with the file extension .PHP.
What we then need is some interactive input fields:
<select name=Tissue>
<option value=0>Unspecified</option>
<option value=1>Brain</option>
<option value=2>Eye</option>
<option value=3>Liver</option>
<option value=4>Heart</option>
<option value=5>Muscel</option>
<option value=5>Splein</option>
</select>
We choice to display a drop down menu with some various items found
in the OPTION-tag. The SELECT as to be refereed with a NAME so we can
refer to it once the START.ASP page is loaded. The name of the variable
that START.ASP will be able to figure out which option we select will
hence be "Tissue".
Finally we need a button to be able to submit the selected data:
<input type=submit value='Go now' name=Submit>
And then we ends the form:
</FORM>
Once we press the "Go Now" button, the form data will be posted to the
webserver, but the handlig page (START.ASP) need a script to extract
the data. This is done like this is VBScript:
Tissue = Request.Form("Tissue")
In PHP I think a reference to a posted variable is done something like this:
$HTTP_POST_VARS['Tissue'];
Knowing this it should be a quite simple to continue with whatever you need to do.
Check this link for more details about POSTing:
