Variable in <FORM> action
Hi,
In script below I try to validate the email address and when it's not correct it should NOT send the form containing the email address. Therefor the 'form' varable ( in <Form action="<?php echo $_SERVER['PHP_SELF'] ?>?form=yes" method="POST"> ) must not be 'yes'. Now the variable is always set to 'yes' but I want it to be 'no' when the email address is not correct. I tried to adjust this line (on the bottom of the script): <Form action="<?php echo $_SERVER['PHP_SELF'] ?>?form=yes" method="POST"> Into something like this <Form action="<?php echo $_SERVER['PHP_SELF'] ?>?form="<?php echo "$eml"; ?>" method="POST"> Where $eml is defiend in the validate_email() function in eighter yes or no. It's head breaking and I can't get it working. Does someone has the solution??? Cheers, Robert p.s. please reply in this newsgroup ----begin script------ <html> <head><title>Nieuwsbrief</title> <?PHP /* Scripting by IPOS (c) 2006 */ /* Function alert double entry email address */ function reenter_email($Email) { $twee_x_email = 0; ?> <form name="contact" action="<?php echo $_SERVER['PHP_SELF'] ?>?form=yes" method="POST"> <table> <tr> <td align="left" valign="top"> <?php print ("<b>Op e-mail adres: <i>".$Email."</i> ontvang je al een nieuwsbrief, voer opnieuw je email adres in:</B><BR><BR>"); ?> E-mail: <input type="text" name="Email" size="50" maxlength="30" onBlur='checkEmailAddress()'><BR></b> </td> </tr> <tr> <td colspan="2" align="center"> <input type="submit" value="Verzend"> <input type="reset" value="Wissen"> </td> </tr> </table> </form> <?PHP return($twee_x_email); return (Email); exit(); } ?> <?php function validate_email($Email) { // First, we check that there's one @ symbol, and that the lengths are right if (!ereg("^[^@]{1,64}@[^@]{1,255}$", $Email)) { // Email invalid because wrong number of characters in one section, or wrong number of @ symbols. $eml="no"; return false; } // Split it into sections to make life easier $email_array = explode("@", $Email); $local_array = explode(".", $email_array[0]); for ($i = 0; $i < sizeof($local_array); $i++) { if (!ereg("^(([A-Za-z0-9!#$%&'*+/=?^_`{|}~-][A-Za-z0-9!#$%&'*+/=?^_`{|}~\.-]{0,63})|(\"[^(\\|\")]{0,62}\"))$", $local_array[$i])) { $eml="no"; return false; } } if (!ereg("^\[?[0-9\.]+\]?$", $email_array[1])) { // Check if domain is IP.
