  1. hi, use array_search, not in_array. array_search gives you the key (index) of the search pattern if it exists. hope this will help.

[!--quoteo(post=356884:date=Mar 21 2006, 08:44 AM:name=firedrop)--][div class=\'quotetop\']QUOTE(firedrop @ Mar 21 2006, 08:44 AM) [snapback]356884[/snapback][/div][div class=\'quotemain\'][!--quotec--] I have another question. when I got for example in a form a submit button I usually use the action in the form and thats in the HTML to allow it to go for the page that I would like. I am wondering what if I have two buttons that they do two different actions. How I can handle this. [/quote] Hi, don't use any action or use action = "<?echo $PHP_SELF?>" to call the same script. Then use an if ... elseif ... else - construct like [code] <?php # Submit - Button #1 if (isset($_POST[submit_button_1]) {    # action for submit - button #1 } // if # Submit -  Button #2 elseif (isset($_POST[submit_button_2]) {    # action for submit - button #2 } // if # Standard - form else {    ?>    <form method = "POST">            .......    </form>    <? } // else ?> [/code]

Please verify that the current setting of session.save_path is correct (/tmp) in Unknown on line 0 [/quote] Hi from Germany, the first error message seems to be php.ini - config problem. you're using windows, the standard php.ini (\tmp) for session dir is no usable under windows. you have do create a directory and add this to your php.ini like session.save_path = C:\Program Files\Apache Group\Apache2\sessions The second and third error message due to the first error message, this was an output and session_start() must be set before any screen output. Hope it will work, webwiese

Then call $_SESSION['loginname'] when I need to access the database? then when they log out simply.... $_SESSION['loginname'] = ''; $_SESSION['password'] = ''; i'm NEW!!!!!!!! SORRY!!!! Thanks D [/quote] Hi, session_start() must be set before any output of your script. For identifying a logged user just ask session_start(); if (isset($_SESSION['loginname']) { ..... code ..... } // if For logout I suggest a unset($_SESSION). webwiese
