Update fields on same page

Anon

This is a newbie question so please bear with me.

What is the best way to update text fields that are on the same page as a drop-down
list, when a user selects data from a drop-down list? From the input of the drop-down
list I plan to query a table and populate the text fields, but I want to do this without
having to use a submit button and going to a different page.

Help!

You will have to use a submit button, but you can make the form action point to the current page you are on using the $PHP_SELF variable, then you would run your query and set your text field values to what ever you like

if ($submit) {

query stuff......

$name = $row["name"];
}

your form here...............

printf('<input type="text" name="name" value="%s"', $name);

Is there a way to do this without having a submit button using maybe javascript?

Since javascript is client side you would still need to submit your form, but you could name your form something like
printf('<form action="%s" method="post" name="theform">', $PHP_SELF);

Then in your dropdown list put:
<select name="whatever" onChange="document.theform.submit(); ">

to automatically submit the form

You can't get around loading (or reloading) a page because you're sending the query results from the server. You CAN do this without a submit button though, and, you're right, the key is javascript.

Your select statement should look something like this:
<input type="select" onchange="formname.submit()">

It might be document.formname.submit() (I can never remember), but that's the idea, anyway. Of course in your form tag, you'll need to have name="formname", where formname is whatever you want to name your form.

HTH,

Beth you should really read previous posts before submitting your own, and sorry there is no <input type="select"> in HTML it is <select name=""></select>

frames.
have the select in one frame, and have it load a different frame with the results of the selection.
