Drop down menu changing values in a form

Question

i have four different sites i would like to search by
entering the search criteria from my page. when they type their
search into the text box and hit submit, it would open a new
window, to the site they searched, displaying the results. i can
accomplish this with four separate forms, however to save space i
would like to combine them all into one form. in the end i would
like one form with one text field, one submit button, and a drop
down menu containing a list of the four different sites they can
search.
how would i do this? the drop down menu would need to change
a few different attributes in a few different tags to get this done
it seems. is that done with javascript? can someone help me out
please?

Answer 1

You could use the input of the drop down to dictate the
redirect URL in your form. i have done this and it depends on what
language PHP ASP CFM? basically look in the code for your
MM_RedirectURL variable and add a if statement after the code that
processes the form like this.
PHP
IF ($_POST['select_field'] = "site1") {
$MM_RedirectURL = "www.example/site1/index.php";
IF($_POST['select_field'] = "site2") {
$MM_RedirectURL = "www.example/site2/index.php";
redirect ("Location: " . $MM_RedirectURL . "");
exit;
This assumes your select field is named "select_field" and
the values are site1, site2. But you could use whatever you want.
Also add two more ifs or use else to make four, the logic works in
any language (at least that i have used)
