With javascriopt or force the user to click a submit button. ... that goes *back* to the server to load a PHP script. So your onChange=... would have something that resulted in: .location=somefancymenuscript.php in it. This would be incredibly inefficient and a really dumb way to do dynamic drop down menus unless you can guarantee high-bandwidth low-latency in an Intranet setting, and even then is probably not truly the BEST answer.

[PHP] dynamic drop down
Hey, I am trying to make a drop down list such that, when some one selects an option, it refreshs and displays the option on the same page. There are a couple of things already in the URL [ the query string ], which need to remain there. How would I do this easily? Regards, Kunal Jhunjhunwala Minds think with ideas, not information.

Re: [PHP] dynamic drop down
Hi Kunul,
I think I have code that does what you want:
function QuickJumpSelect($name=, $optionvalues, $optionnames, $stylestr=)
{
($stylestr != )? $style = $stylestr : $style = ;
// Calculate stuff
$count = count($optionnames);
$output = ;
// -- Start outputting the SELECT --
$output .= SELECT NAME=\$name\$style $size OnChange=JumpToRef(this);
$output .= option value=\\Jump to:/option\n;
for($idx = 0; $idx $count; ++$idx){
$name = $optionnames[$idx];
$val = trim($optionvalues[$idx]);
$output .= option value=\$val\$name/option\n;
}
$output .= /SELECT\n;
return $output;
} // - end function
---
Call it like this:
$JumpPad = QuickJumpSelect(EenieMeenieMinyMoe, $array_of_urls,
$array_of_names_to_show_in_list, $stylestring);
stylestring is a CSS argument, like:
$stylestring = style=\width: 100px; font-family: Arial; font-size: 10px\;
Now you can just print $JumpPad where you want it to be.

All the best,
Eivind :-)

Re: [PHP] dynamic drop down
Are you talking about refreshing/dynamicly modifying the pull-down (client side, javascript), or refreshing the page (server side, php)?? You can set a pull down to submit the form onchange, (check out javascript sites for this FAQ) and the action of your form would be something like (untested): FORM action=?= $PHP_SELF.?.$QUERY_STRING ? method=post This will call the current page, with the current query string, which I thin is your question.

First, you need to use JavaScript (I think the onchange handler) to automatically submit the form when the user selects an option from the dropdown list. That's no big deal. But to maintain the querystring, you will need to do a bit of finagling -- but it's nothing hard. You could either use $_SERVER['QUERYSTRING'] and place the value of this variable into a hidden form field, or you could do a foreach ($_GET) and concatenate the results into a string and place that into a hidden form field.

RE: [PHP] dynamic drop down
Do you want to submit every time the dropdown changes? If you just want the second dropdown to update and don't want a submit, let me know. I am doing this in one of my programs and I can send you some code if you think it would help. Ex of my program: We want to show populations. There's a state box and when you select a state then the county box fills up with counties for that state (along with an Entire State option). We have them set up using boxes that are 3 tall, I think (maybe 5). For some reason it didn't work as well when we did regular dropdowns, so this was our current workaround. We use onload in the body tag, onchange in the state box tag, and use a JS method to populate the second dropdown. Good luck! -Natalie -Original Message- From: Erik Price [mailto:[EMAIL PROTECTED]] Sent: Tuesday, April 23, 2002 10:02 AM To: Kunal Jhunjhunwala Cc: php-list Subject: Re: [PHP] dynamic drop down On Tuesday, April 23, 2002, at 07:01 AM, Kunal Jhunjhunwala wrote: I am trying to make a drop down list such that, when some one selects an option, it refreshs and displays the option on the same page.

[PHP] Dynamic Drop-down list

the default item (the one showing to the surfer) is the last in the
list. Is there a way I can have the first item show?

RE: [PHP] Dynamic Drop-down list
the 'SELECTED' attribute will select an item in a dropdown list.
by default, with no SELECTED attribute, the first item will be shown and
selected.
make sense?
