Hello

I need to limit the number of submissions per form, for this I'm using the following script:

__________________________________________________________________>>

Script called on form display

/*THIS SCRIPT LIMITS SUBMISSIONS TO 10*/
$submissions = @mysql_result(mysql_query("SELECT COUNT(`SubmissionId`) FROM ".$RSadapter->tbl_rsform_submissions." WHERE `formId`='".$formId."'"),0);
if (intval($submissions) >= 10)
{
//the formLayout variable contains all the form output. let's overwrite it
$formLayout = '<font color="red">Sorry, no more submissions are accepted !</font>';
}

/*LET'S DISPLAY THE NUMBER OF CURRENT SUBMISSIONS*/
/*YOU CAN DELETE THIS LINE, IF YOU DON'T NEED IT*/
$formLayout .= 'Current number of submissions: '.mysql_result(mysql_query("SELECT COUNT(`SubmissionId`) FROM ".$RSadapter->tbl_rsform_submissions." WHERE `formId`='".$formId."'"),0);
$formLayout .= ' (10)';


Script called on form process

$submissions = @mysql_result(mysql_query("SELECT COUNT(`SubmissionId`) FROM ".$RSadapter->tbl_rsform_submissions." WHERE `formId`='".$formId."'"),0);
if (intval($submissions) >= 10)
{
//If you are showing the form inside an article, replace the link below with the article link
$redirectLink = 'index.php?option=com_rsform&formId='.$formId;
$RSadapter->redirect($redirectLink,'Sorry, no more submissions are accepted !');
