[PHP4BETA] cookie, post method form, cycling background From: Cynic (cynic <email protected>)
Date: 04/28/00

This is my first attempt with cookies, I've run into a prob,
and unfortunatelly, it's 3 AM here. Just can't see it.
Apache / 4b RC2-dev on NT, MSIE5.0 & CC4.7 on NT

goal: 5 backgrounds. User clicks the submit button, next
backbround is displayed, and its number is stored in a cookie.
1 -> 2 -> 3 -> 4 -> 5 -> 1 -> 2 ...

The prob:

display the page, submit the form... nothing happens. (1) submit
again, get the next background... ok. go someplace else, then
back to the page (or reload the page), get the next background.
(2) submit the form, nothing happens, submit again, get the next
background.

Why do those two things happen?

<?

        if ( ! isset( $HTTP_COOKIE_VARS['divcookie'] ) )
        {
                $div = 1 ;
        }
        else
        {
                $div = $HTTP_COOKIE_VARS['divcookie'] ;
        } ;

        if ( 1 == $submitted )
        {
                ( 5 == $div ) ? $setdiv = 1 : $setdiv = $div + 1 ;
                setcookie( 'divcookie' , $setdiv , time() + 100000000 , '/e2/div/' , 'cynic.bewotec.cz' , 0 ) ;
        } ;

?>
+HTML>
+HEAD>
+/HEAD>
+BODY BACKGROUND="/e2/images/div<?= $div ?>.gif" BGCOLOR="#800000">
<?
        echo $HTTP_COOKIE_VARS['divcookie'] ;

?>
+TABLE BORDER="0" CELLSPACING="0" CELLPADDING="0" COLS="1" HEIGHT="100%">
+TR VALIGN="BOTTOM">
        +TD VALIGN="BOTTOM">
                +FORM ACTION="<?= $REQUEST_URI ?>" METHOD="post">
                        +INPUT TYPE="hidden" NAME="submitted" VALUE="1">
                        +INPUT TYPE="Image" SRC="/e2/images/div.gif">
                +/FORM>
        +/TD>
+/TR>
+/TABLE>

+/BODY>
+/HTML>

Btw, sorry for the strange HTML tags, but I can't get
my Eudora send mail in a reasonable way.
