Each field in a module has two native types of validation:

• data type validation: when you define a field on a module you indicate the type that it is; integer, string, currency, date, … So when you are editing a record with that field on-screen coreBOS will automatically ensure that the value introduced is of the correct type.

• mandatory validation: you can indicate which fields must contain a value, in other words, they cannot be left empty

Besides these two types which are supported by all fields, and some additional undocumented tricks that can be done using an extended syntax in the typeofdata field, there are only a handful of hardcoded validations in the system:

• no accountname duplicates

• mandatory email on contact if portal user checked

• contact birthday

• sales order recurring settings

• start and end dates on calendar

If you want to add your own validations, for the moment you will have to add some code.

Each module supports special validations that can be done in a PHP file called:

{ModuleName}Validation.php

which must live inside the module's directory.

So, for example, you can see in the application the file

modules/Accounts/AccountsValidation.php

which contains the validation of “no duplicate accountname”.

All these validation files support the same syntax; they will receive an array of all the values that are currently in the user's browser in the $_REQUEST variable called structure and they must return one of three outputs:

1. OK
   to indicate that all validations have passed correctly

2. CONFIRM
   followed by any message to produce a screen that will ask for confirmation using the text following the CONFIRM label

3. Any other output/message which will be interpreted as an error message that will be shown to the user

Examples

No duplicate Leads based on email and phone:

global $log,$currentModule,$adb;
 
$screen_values = json_decode($_REQUEST['structure'],true);
 
$query = 'SELECT count(*) as cnt
	FROM vtiger_leaddetails
	INNER JOIN vtiger_crmentity on vtiger_leaddetails.leadid = vtiger_crmentity.crmid
	INNER JOIN vtiger_leadscf on vtiger_leaddetails.leadid = vtiger_leadscf.leadid
	INNER JOIN vtiger_leadaddress on vtiger_leaddetails.leadid = vtiger_leadaddress.leadaddressid
	WHERE vtiger_crmentity.deleted = 0 and vtiger_leaddetails.converted=0 ';
 
$email = vtlib_purify($screen_values['email']);
$phone = vtlib_purify($screen_values['phone']);
if (!empty($email) and !empty($phone)) {
	$query.='and (email = ? or phone = ?) ';
	$params = array($email,$phone);
} elseif (!empty($email)) {
	$query.='and email = ? ';
	$params = array($email);
} elseif (!empty($phone)) {
	$query.='and phone = ? ';
	$params = array($phone);
} else {
	echo '%%%OK%%%';
	die();
}
 
$id = vtlib_purify($screen_values['record']);
if(!empty($id)) {
	$query .= 'and vtiger_leaddetails.leadid != ?';
	array_push($params, $id);
}
 
$result = $adb->pquery($query, $params);
if($adb->query_result($result,0,'cnt') > 0) {
	echo getTranslatedString('LBL_LEAD_EXISTS','Leads');
	die;
}
 
echo '%%%OK%%%';

No duplicate contacts based on email

global $log,$currentModule,$adb;
 
$screen_values = json_decode($_REQUEST['structure'],true);
 
$query = 'SELECT count(*) as cnt
	FROM vtiger_contactdetails
	INNER JOIN vtiger_crmentity on vtiger_contactdetails.contactid = vtiger_crmentity.crmid
	INNER JOIN vtiger_contactaddress on vtiger_contactaddress.contactaddressid=vtiger_contactdetails.contactid
	INNER JOIN vtiger_contactsubdetails on vtiger_contactsubdetails.contactsubscriptionid=vtiger_contactdetails.contactid
	INNER JOIN vtiger_contactscf on vtiger_contactscf.contactid=vtiger_contactdetails.contactid
	WHERE vtiger_crmentity.deleted = 0 ';
 
$email = vtlib_purify($screen_values['email']);
if (!empty($email)) {
	$query.='and (email = ? or secondaryemail = ?) ';
	$params = array($email,$email);
} else {
	echo '%%%OK%%%';
	die();
}
 
$id = vtlib_purify($screen_values['record']);
if(!empty($id)) {
	$query .= 'and vtiger_contactdetails.contactid != ?';
	array_push($params, $id);
}
 
$result = $adb->pquery($query, $params);
if($adb->query_result($result,0,'cnt') > 0) {
	echo getTranslatedString('LBL_CONTACT_EXISTS','Contacts');
	die;
}
 
echo '%%%OK%%%';

Blocked Quotes depending on Quote Stage

global $log,$currentModule,$adb;
 
$screen_values = json_decode($_REQUEST['structure'],true);
 
$record = vtlib_purify($screen_values['record']);
$closedstages = array('Approved','Cancel','Paid','Delivered');
if (!empty($record)) { // editando
	$qrs = $adb->pquery('SELECT quotestage FROM vtiger_quotes WHERE quoteid=?',array($record));
	if ($qrs and $adb->num_rows($qrs)>0) {
		$dbqstage = $adb->query_result($qrs, 0, 0);
		//$frqstage = vtlib_purify($_REQUEST['quotestage']);
		if (in_array($dbqstage, $closedstages)) {
			echo 'This quote is closed. Please duplicate it to edit and change.';
			die();
		}
	}
}
 
echo '%%%OK%%%';
