Validation Business Mapping

This type of map will permit you to add different types of validations on the fields of a module.

The accepted format is 

 <map>
  <originmodule>
    <originname>SalesOrder</originname>
  </originmodule>
  <fields>
    <field>
      <fieldname>subject</fieldname>   {field to validate}
      <validations>  {if more than one is present they must all pass to accept the value}
        <validation>
          <rule>{rule_name}</rule>
          <restrictions>
          <restriction>{values depend on the rule}</restriction>
          </restrictions>
          <message>This is my custom msg for field: {field}</message>  {optional}
        </validation>
        .....
      </validations>
    </field>
    <field>
     .....
    </field>
  </fields>

where {rule_name} can be:

  • required - Required field
    • restrictions: none

    • restrictions: name of the other field
  • different - Field must be different than another field

    • restrictions: regular expression. be careful you may have to put this inside a CDATA
  • date - Field is a valid date
    • restrictions: none

    • restrictions: date in ISO format
  • contains - Field is a string and contains the given string

    • restrictions: none
  • notDuplicate - checks that no other record with the same value exists on the given fieldname
    • restrictions: none
  • expression - accept a workflow expression map and evaluate it in the context of the new screen values
    • restrictions: map name or id
  • custom - launch custom function that can be found in the indicated file
    • restrictions: file name, validation test name, function name and label to show on error (will be translated)

All of the rules above accept an optional directive named message where you can set the error message you want the user to see when an error on that field happens. If this is not established a standard error message will be returned. Inside this message you can use the curly brace field tag to indicate where you want the field name to appear: 

<message>This is my custom msg for field: {field}</message>

The trigger for these maps is that they must be of type “Validations” and the “Target Module” must be set correctly. If more than one record is found, they will ALL be applied.

Accessing other fields in the form

You can use the values of other fields on the form by putting the field name inside two curly brackets. For example, the next map will validate that the field dtstart is before the value in field dtend. 

<map>
  <originmodule>
    <originname>cbCalendar</originname>
  </originmodule>
  <fields>
    <field>
      <fieldname>dtend</fieldname>
      <validations>
        <validation>
          <rule>dateAfter</rule>
          <restrictions>
          <restriction>{{dtstart}}</restriction>
          </restrictions>
        </validation>
      </validations>
    </field>
  </fields>
</map>

There is an important limitation when using the values of other fields. These values will only be available when editing the whole record. If the user is doing inline individual field edit on the detail view, the value of the other fields will not be available. To overcome this limitation, you need to create a custom validation rule and access the values you need from the database.

Other information available during validation

In order to enhance the set of possible validations that can be done, the validation system automatically adds some values that you can use freely.

Current values

When editing a record it is possible to want to compare the value introduced by the user with the value that is currently saved in that same field or some other field with which it may have some dependency. In this case you can access these values prefixing the string “current_” to the variable name. For example, let's suppose that we are editing an Account, the user has changed the Industry picklist value and we want to check what the currently saved value is before accepting the change. Let's imagine a rule that says:

Any account who's industry is set to Banking, cannot be changed

In this case, we can easily access the value that the user has selected by putting the industry field and to access the value saved in the application we would use: current_industry, something like this: 

<map>
  <originmodule>
    <originname>Accounts</originname>
  </originmodule>
  <fields>
    <field>
      <fieldname>current_industry</fieldname>
      <validations>
        <validation>
          <rule>notIn</rule>
          <restrictions>
          <restriction>Banking</restriction>
          </restrictions>
        </validation>
      </validations>
    </field>
  </fields>
</map>

Product lines

In inventory modules, the system will load all the information of the lines into the pdoInformation array which will look something like this: 

pdoInformation => array(
 array(
  'crmid' = {first line product/service ID},
  'qty' = {first line quantity (units)},
  'name' = {first line product/service name},
  'type' = {first line product/service type},
 ),
 ... all product/service lines ..

Some other examples

Another example of how to limit the accepted values in a picklist, even making it mandatory if needed. 

<map>
  <originmodule>
    <originname>cbCalendar</originname>
  </originmodule>
  <fields>
    <field>
      <fieldname>activitytype</fieldname>
      <validations>
        <validation>
          <rule>notIn</rule>
          <restrictions>
          <restriction>Call</restriction>
          <restriction>Meeting</restriction>
          </restrictions>
        </validation>
      </validations>
    </field>
  </fields>
</map>

This next example contains a REGEX expression that will not accept any alphabetical letter in the accountname field and there must be at least one character. Important things to notice in the REGEX expression are:

  1. you must set the initial and end of line markers as the value is compared as a complete string
  2. you may or may not need the CDATA depending on the regex (the one below does not need CDATA)
  3. modifiers are not supported in the expression
<map>
  <originmodule>
    <originname>Accounts</originname>
  </originmodule>
  <fields>
    <field>
      <fieldname>accountname</fieldname>
      <validations>
        <validation>
          <rule>regex</rule>
          <restrictions>
          <restriction><![CDATA[/^[^A-Za-z]+$/]]></restriction>
          </restrictions>
        </validation>
      </validations>
    </field>
  </fields>
</map>

Custom Validations

coreBOS has some custom validations that are not loaded by default but can be used if necessary:

  • Brazilian ID Number: file include/validation/validateCPFCNPJ.php
    • validaCPF
    • validaCNPJ
    • validaCNPJ2
  • Spanish ID Number: file include/validation/validatorESIDNumber.php
    • isValidDNI
    • isValidNIE
    • isValidNIF
    • isValidCIF
    • isValidPersonalESID = isValidDNI or isValidNIE or isValidNIF
    • isValidESID = isValidPersonalESID or isValidCIF
  • Italian ID Number: file include/validation/validatePIVA.php
    • checkAccountPIVA

For example, a validation for a valid CIF on account siccode field looks like this: 

<map>
  <originmodule>
    <originname>Accounts</originname>
  </originmodule>
  <fields>
    <field>
      <fieldname>siccode</fieldname>
      <validations>
        <validation>
          <rule>custom</rule>
          <restrictions>
          <restriction>include/validation/validatorESIDNumber.php</restriction>
          <restriction>isValidCIF</restriction>
          <restriction>isValidCIF</restriction>
          </restrictions>
        </validation>
      </validations>
    </field>
  </fields>
</map>

Test Validation Business Mapping

These are the two validation maps I used while developing the integration of the mapping in the save process: 

<map>
  <originmodule>
    <originname>Accounts</originname>
  </originmodule>
  <fields>
    <field>
      <fieldname>accountname</fieldname>
      <validations>
        <validation>
          <rule>required</rule>
        </validation>
        <validation>
          <rule>contains</rule>
          <restrictions>
          <restriction>mex</restriction>
          </restrictions>
        </validation>
      </validations>
    </field>
    <field>
      <fieldname>industry</fieldname>
      <validations>
        <validation>
          <rule>notDuplicate</rule>
        </validation>
      </validations>
    </field>
  </fields>
</map>
<map>
  <originmodule>
    <originname>Accounts</originname>
  </originmodule>
  <fields>
    <field>
      <fieldname>email1</fieldname>
      <validations>
        <validation>
          <rule>custom</rule>
          <restrictions>
          <restriction>modules/cbMap/Validation.php</restriction>
          <restriction>testemail</restriction>
          <restriction>validate_testacccemail</restriction>
          </restrictions>
        </validation>
      </validations>
    </field>
  </fields>
</map>

both are set for the Accounts module.

This is the custom validation script: 

function validate_testacccemail($field) {
	global $log;$log->fatal('validation for'.$field);
	return true;
}

Expression Map

<map>
  <originmodule>

      </validations>
    </field>
  </fields>
</map>
<map>
  <expression>if employees > 10 then 1 else 0 end</expression>
</map>
