I often do this too. It's great because you can do all your permission
checking,etc. in one place. You do have to be a little careful with this
though because someone could easily catch on and override your action with
an undesireable alternative. If both actions use roughly the same variables
and you don't do some checking, they could initate a delete when you really
only wanted them doing an update. It might be safer to use a:

switch ( $HTTP_POST_VARS["action"] )

In my applications I point all my forms to the same action page index.php.

index.php consists of a switch statement, something like

switch ($action) {
case "updateRecord":
   include "act_updaterecord.php";
   break;
case "findRecord":
   include "act_findrecord.php";
   break;
case "displayRecord":
   include "dsp_displayrecord.php";
   break;
default:
   include "dsp_main.php";
   break;
}

Then in my form I have a hidden field named action.

$f->ae("type"=>"hidden",
       "name"=>"action"));

When a submit button is clicked I set action to the relevant value.
e.g.
$f->ae("type"=>"submit",
       "name"=>"Update",
       "value"=>"Update",
       "extrahtml"=>"onclick=\"action.value='updateRecord'\""

If my form has only one text field - as in your case - I initialise the
value of action to the relevant value.

e.g.
$f->ae("type"=>"hidden",
       "name"=>"action",
       "value"=>"findRecord"));

$f->ae("type"=>"text",
       "name"=>"Find",
       "value"=>""));

You could use JavaScript to set the value for you.

First in you header define what setSubmit does like
<script>
    function setSubmit() {
        document.MyForm.Mysubmit.value = "Submitted";
    }
</script>

In your form declaration you would put something like

<form name="MyForm" onSubmit="setSubmit()">
. . .
    <input type="hidden" name="MySubmit" value="">
</form>

This is a very rough suggestion and you will need to flesh it out. YMMV...
