Retaining Drop down menu value

[sanjdhiman]

Hi there im using php mySQL and apache in the normal fashion. on winXP Home..

I have a form which lets users choose values from drop down menus and text fields however, when i mvoe to next page im able to retain the text field values, i.e. using session variables. so when i press the back button it has all the info in the text boxes BUT the drop down menu boxes dont retain there value even if i REgsister them as session variables?

do i need to do something am i missing something?

example of code

<input type=\&quot;text\&quot; name=\&quot;feature1\&quot; value =\&quot; <? echo $feature1; ?>\&quot;>

The above retains its value
BUT
<select name=&quot;propertytype&quot;>
<option value=&quot;flat&quot;>Flat</option>
...
...

this does not
how do i make it so that it will retain its value on screen if i come back to it?

regards

and thanks in advance

these are a bit of a pain to code :

echo &quot;<select name=\&quot;propertytype\&quot;>\n
<option value=\&quot;flat\&quot; &quot;;
if($propertytype == &quot;Flat&quot{
echo &quot;SELECTED&quot;;
echo &quot;>Flat</option>;
...
...

sorry to bother i have managed to implement the option block... but wsa wondering if u could help me with another little problem

ok the page where the form is has the options and text boxes etc/....

when i enter stuff in there and then go to next page as in submit it

its fine

but WHEN i go back to the form page for examplei might have made a mistake and change the info and hten press submit again it dont change it keeps/retains the old values???

note i am using session_register for each form element?

can u think why this is happeneing?

regards

and thanks for the help

Hi!

When you register a variable with the session, it is retained once it is set.
Your first submit sets let's say variable $a to &quot;set&quot;.
You return to the previous page and just select variable $b, then submit.
Then you'll have both $a and $b in your session unless you unset $a.

Another thing:
The 'back&quot; button is often the killer of dynamic pages. When you just go back and there is no forced refresh you basically go back into the past. This, however, does not change your PHP session values. You need to rebuild the page so it doesn't come from the browser cache.

thanks for the help
