RE: [PHP] form field update

So throw a little onchange= event into "machine_group" that submits the form and then dynamically generates the <options> for "machine_type". In order for the other form stuff to retain it's value, you have to put it there. <input type='text' name='whatever' value='<?=$_POST['whatever']?>'> When the form is first loaded, $_POST['whatever'] will be empty, so the text box will be also. When the form is submitted, $_POST['whatever'] will contain the value in the text box, so if you have to redisplay the form, now it'll be filled. You may have to adjust your error_reporting() so you don't see an error about Undefined Offset 'whatever' when you first load the page... ---John Holmes... > -----Original Message----- > From: Peter [mailto:php@vfsa.com.au] > Sent: Sunday, June 16, 2002 10:45 PM > To: Php > Subject: RE: [PHP] form field update > > ok to make it clearer... > > <form ......> > <other form stuff> > <select name="machine_group" size="1" id="machine_group"> > <option value="ws" >Work Station</option> > <option value="serv" >Server</option> > <option value="stor">Storage</option> > <option value="bu">Back Up</option> > </select> > > <select name="machine_type" size="1" id="machine_group"> > > the info in here needs to be gathered depending on what was selected > > <option value="$value" >$machine_type</option> > > </select> > <more form stuff> > </form> > > now what i want to do is have the option values in machine_type to > automatically load depending on what was selected in machine_group with > the > options in machine_type repeating until no more records are found > matching. > The repeating part i can do no worries .. hope this made sence > **All other form info must be retained....** > -----Original Message----- > From: Martin Towell [mailto:martin.towell@world.net] > Sent: Monday, 17 June 2002 11:46 AM > To: 'Peter'; Php > Subject: RE: [PHP] form field update > > > depends on what's being updated (and where that info is coming from), and > if > you're willing to allow the data the user has typed in to disappear after > a > refresh > > -----Original Message----- > From: Peter [mailto:php@vfsa.com.au] > Sent: Monday, June 17, 2002 11:50 AM > To: Php > Subject: [PHP] form field update > > > howdy, > > I am building a page that relies on a form... > what I am unsure of is .. > is it better to try and have form fields update them selves, using java > script or the like or have the whole page refreshed with out being > submitted > given there will be other data entered on the page.. > > > Cheers > > Peter > "the only dumb question is the one that wasn't asked" > > > > -- > PHP General Mailing List (http://www.php.net/) > To unsubscribe, visit: http://www.php.net/unsub.php > > > -- > PHP General Mailing List (http://www.php.net/) > To unsubscribe, visit: http://www.php.net/unsub.php
