frm_display_form_action

Use this code to limit the total number of entries that can be submitted for a particular form. This code will check if your entry limit has been reached and if it has, then the form will not be displayed.

add_action('frm_display_form_action', 'limit_entry_count', 8, 3);
function limit_entry_count($params, $fields, $form){
	remove_filter('frm_continue_to_new', '__return_false', 50);
	if ( in_array($form->id, array(5,6,7)) ) { //change 5, 6, and 7 to your form ID(s)
		$count = FrmEntry::getRecordCount($form->id);
		if ( $count >= 15 ) { //change 15 to your entry limit
			echo 'This form is closed';
			add_filter('frm_continue_to_new', '__return_false', 50);
		}
  	}
}

add_action('frm_display_form_action', 'check_entry_count', 8, 3);
function check_entry_count($params, $fields, $form){
  global $user_ID;
  remove_filter('frm_continue_to_new', '__return_false', 50);
  if($form->id == 5 and !is_admin()){ //replace 5 with the ID of your form
    $count = FrmEntry::getRecordCount("form_id=". $form->id ." AND user_id=".$user_ID); 
    if($count >= 2){ //change 2 to your entry limit
      echo 'This form is closed';
      add_filter('frm_continue_to_new', '__return_false', 50);
    }
  }
}

add_action('frm_display_form_action', 'check_entry_count', 8, 3);
function check_entry_count($params, $fields, $form){
	remove_filter('frm_continue_to_new', '__return_false', 50);
	if($form->id == 5 and !is_admin()){ //replace 5 with the ID of your form
		$count = FrmEntry::getRecordCount( array('form_id' => $form->id, 'it.ip' => $_SERVER['REMOTE_ADDR'] ) ); 
		if($count >= 2){ //change 2 to your entry limit
			echo 'This form is closed';
			add_filter('frm_continue_to_new', '__return_false', 50);
		}
	}
}

NOTE: You may need to customize this code to work for your timezone

add_action('frm_display_form_action', 'check_entry_count', 8, 3);
function check_entry_count($params, $fields, $form){
  remove_filter('frm_continue_to_new', '__return_false', 50);
  global $user_ID;
  if($form->id == 5 and !is_admin()){ //replace 5 with your form ID
    $count = FrmEntry::getRecordCount("form_id=". $form->id ." AND it.created_at > '". gmdate('Y-m-d')." 00:00:00' AND user_id=".$user_ID); 
    //$count = FrmEntry::getRecordCount("form_id=". $form->id ." AND it.created_at > '". gmdate('Y-m')."-01 00:00:00' AND user_id=".$user_ID); // uncommented this line to limit by month instead of day
    if($count >= 2){ //change 2 to your limit
      echo 'This form is closed';
      add_filter('frm_continue_to_new', '__return_false', 50);
    }
  }
}

add_action('frm_display_form_action', 'check_entry_count', 8, 3);
function check_entry_count($params, $fields, $form){
  global $user_ID;
  remove_filter('frm_continue_to_new', '__return_false', 50);
  if($form->id == 5 and !current_user_can('administrator')) { //change 5 to the form ID
    $one_day_ago = strtotime(current_time('mysql', 1)) - (60*60*24); //calculate 24 hours ago
    $count = FrmEntry::getRecordCount("it.created_at > '".date('Y-m-d H:i:s', $one_day_ago)."' and user_id=".$user_ID);
    if($count >= 2){
      echo 'Sorry - only two entries per 24hrs per user - please try again later ...';
      add_filter('frm_continue_to_new', '__return_false', 50);
    }
  }
}

Only show your form before a specified date. This example closes the form on 2012-05-15.

add_action('frm_display_form_action', 'close_my_form', 8, 3);
function close_my_form($params, $fields, $form){
  remove_filter('frm_continue_to_new', '__return_false', 50);
  if($form->id == 6){ //remove this section or change 6 to a form ID
    if(time() > strtotime('2012-05-15')){
      echo 'This form has expired';
      add_filter('frm_continue_to_new', '__return_false', 50);
    }
  }
}

add_action('frm_display_form_action', 'close_my_form', 8, 3);
function close_my_form($params, $fields, $form){
  remove_filter('frm_continue_to_new', '__return_false', 50);
  if($form->id == 6){ //remove this section or change 6 to a form ID
    if(is_user_logged_in()){
      echo 'You are logged in';
      add_filter('frm_continue_to_new', '__return_false', 50);
    }
  }
}

If someone changes the id of the entry in a url to edit, they will see a blank form. This example will show a message instead of the empty form.

add_action('frm_display_form_action', 'close_my_form', 20, 3);
function redirect_edit_form( $params, $fields, $form ) {
  global $frm_vars;
  $edit_attempt = isset( $_GET['entry'] );
  $editing_entry = isset( $frm_vars['editing_entry'] ) ? $frm_vars['editing_entry'] : 0;
  if ( $edit_attempt && ! $editing_entry ) {
    echo 'You do not have permission to edit that entry.';
    add_filter('frm_continue_to_new', '__return_false', 50);
  }
}

You can use stats to determine whether a form should be open.

• Change 194 to the id of your form.
• Change 893 to the id of a field that always has content in your form.
• Change the other params like 'type'=>'count', 'user_id'=>'current', and 'created_at_greater_than'=>'-4 months" to the params you'd like to use in your stat.
• Change 1 to the limit you want to use.
• Change the message "You have already submitted this form in the last four months" to the message you want to display

add_action( 'frm_display_form_action', 'limit_entry_by_stat', 8, 3 );
function limit_entry_by_stat( $params, $fields, $form ) {
	remove_filter( 'frm_continue_to_new', '__return_false', 50 );
	if ( $form->id == 194 ) { //change 194 to your form ID
		$count = FrmProStatisticsController::stats_shortcode( array( 'id'                      => 893,
		                                                             'type'                    => 'count',
		                                                             'user_id'                 => 'current',
		                                                             'created_at_greater_than' => "-4 months"
		) );
		if ( $count >= 1 ) { //change 2 to your entry limit
			echo 'You have already submitted this form in the last four months.';
			add_filter( 'frm_continue_to_new', '__return_false', 50 );
		}
	}
}
