<? // cookie.php3 // // by Jeff Schmitt // Towson University // March, 1998 // /* Date: Wed, 8 Apr 1998 01:51:04 -0400 From: "Brian M. Platz" <platz.brian@infoband.com> The syntax is: SetCookie($name,$value,$expire_time,$directory,$domain,$secure); $name - name of the cookie $value - value of the cookie $expire_time - [optional] time in UNIX epoch seconds when cookie should expire. This is optional, and if not specified will expire after the user 'session', or after they exit your domain/directory specified. $directory - [optional] directory under web server this cookie is for. Defaults to the directory of the requested page. $domain - [optional] domain name this cookie can be used under. Defaults to domain name of requested page. Must have TWO '.' in the name, so if you specify your A level, you must use ".mydomain.com" $secure - [optional] if set to '1', this cookie will only be sent over secure server, or an 'https://' request. if your document is /mydir/index.php3 and you set a cookie using SetCookie("mytest", "this is a test cookie"); you will only be able to access $mytest for document under the /mydir/ directory tree. To set a cookie that will expire after the current session, and will work for your entire domain.. use the following: SetCookie("mytest", "this is a test cookie", 0, "/", ".yourdomain.com"); As for retrieving the value of a cookie, it is automagically URL decoded and put in a variable. As for "if (!SetCookie("mytest", "this is another test")) {", I don't think SetCookie() returns a value. I could be wrong. -Brian Platz */ // This code must go before the HTML header has been sent // in other words it preceedes all echo and <HTML> code // we increment a hard-coded cookie variable: $cookiecount SetCookie("cookiecount", ++$cookiecount, 0, "/", ".towson.edu"); // look at the HTML form variables if ($action) { // set the cookie variable // append "cookie" to name of the variable // so it can easily be found in list of global variables SetCookie("cookie".$name, $value, 0, "/", ".towson.edu"); echo "<P>Setting Cookie: $name to $value<BR>\n"; echo "(reload this form to see if this value is reported)\n"; } ?> <HTML><HEAD> <TITLE>cookie test</TITLE> </HEAD> <BODY> <H2>cookie test</H2> <? echo "<P>Reporting your cookies:<BR>\n"; while (list($key, $value) = each($GLOBALS)) { if (ereg('cookie',$key)) { echo "$key: $value<BR>\n"; } } ?> <HR NOSHADE> <H3> Set some cookie values: </H3> <FORM METHOD="POST" ACTION="<?echo $PHP_SELF;?>"> <TABLE BORDER=1> <TR><TH>Name: <TD><INPUT NAME="name" size=8 MAXLENGTH=8> <TH>Value: <TD><INPUT NAME="value" size=30 MAXLENGTH=30> <TR><TH>Action: <TD><INPUT TYPE="SUBMIT" NAME="action" VALUE="Submit"> <TD><INPUT TYPE=RESET VALUE="Clear Form"> </TABLE> </FORM> </BODY> </HTML> | |||||
