hello

i want to create form which allow me to automaticly count limited number of invitation.

So i need contact informatios and one field which will be containing number of requested number of invitations. General number of invitation should be stored in database or file for futher calculation.

So how to consider this ?can i do it through only cforms ? or rather should i use java to take number from form and store it to file ?

cforms supports 'counting' of submissions directly, see "Core Form Admin / Email Options". there is also an API call (Help page) to retrieve number of submissions left…

right, in that case you need to custom code something

no, at this moment it is very short and simple code which is included on page with form. ( i have exec-php plugin installed which allows to include code on page).

<?php
add_option("zaproszenia", '100', '', 'yes');
$zapro=$_POST["cf4_field_1"];

$all_zapro=get_option('zaproszenia');

$option_name = 'zaproszenia' ;
$newvalue = $all_zapro-$zapro ;
  if ( get_option($option_name) ) {
    update_option($option_name, $newvalue);
}
echo "<strong>Liczba dostępnych zaproszeń: ";
echo get_option('zaproszenia'); 
echo "</strong>";
?>
