Forms Question

hmogan

Hi gang,

I have a couple of issues and would appreciate any help:

I have a form that has 2 dynamic drop down menus in it and when i select
the first one, i need to look up the value selected and dynamically create
the second as they are categories and subcategories. I have this working
fine thanks to a bit of javascript
(onChange="javascript:document.Form.submit()'" with the action of the form
as =$PHP_SELF) This seems to be working fine.

When the page reloads, the variables in the form are set (as verified by
clunky echo statements at the top) however the fields are displayed empty.
Any way to cause these fields to fill other then step through them one by
one and set them with javascript?

Whilst problem 1, the categories and subcategories is working fine, i
would like a submit down the bottom of the page, but in the same form, to go
to a different page (a different action?) for verification. How do i go
about this?

Many thanks for your help

I suggest you store your drops down in an associative array (name=key and value=value), then you can simply do:

echo '<select name="stuff">';
foreach ($array as $key => $value)
{
echo '<option'; if (isset ($stuff) && $stuff == $key) {echo ' selected';} echo '>' . $value . "\n";
}
echo '</select>';

when this form is reloaded it will remeber the user input values

You can point a form to any form handler you want:
<form action="whatever.php">

Many thanks, i, for some inconceivable reason was dreading putting all the data of the menus in Javascript arrays! My humble apologies to the coding community at large 🙂

Its definately remembering the values, however, on reload, the fields are empty but the values are set. Am i missing something? My logic tells me that if a textfield is named username and $username="blah" then the text, on reload, in the textfield should = "blah".

not necessarily. you would have to do:

echo '<input type="text" name="username" value="'; if (isset ($username)) {echo $username;} echo '">';
