Adding Field Display Logic

When making these changes be sure to make them in the custom directory, ie: 'public/legacy/custom/modules/<module>/…'

1. Introduction

Display logic allows you to define rules to hide and show fields depending on other fields values.

As an example of how to hide a field, we are going to add configurations to the phone_office field on the Accounts Module. The configuration we add will set the field to hide when the Account Name is Example.

2.Logic Metadata definition

The first thing to define is the displayLogic entry in the metadata. This is where we are going to define the triggers to hide/show our field.

The configuration for the logic can be added to the vardefs.php or the detailviewdefs.php.

In the following example we are going to add them to the Accounts module field vardefs.

2.1 Steps to add the logic on the custom vardefs

Create a new field in custom extensions for Accounts module:
1. Example: public/legacy/custom/Extension/modules/Accounts/Ext/Vardefs/annual_revenue.php
Copy the 'phone_office' definition from public/legacy/include/SugarObjects/templates/company/vardefs.php
Replace the logic entry to the phone_office definition with the code on the snippet below.
- Re-set permissions if needed (will depend on your setup)
Run Repair and Rebuild on Admin menu

<?php

$dictionary['Account']['fields']['phone_office'] = array(
    'name' => 'phone_office',
    'vname' => 'LBL_PHONE_OFFICE',
    'type' => 'phone',
    'dbType' => 'varchar',
    'len' => 100,
    'audited' => true,
    'unified_search' => true,
    'full_text_search' => array('boost' => 1),
    'comment' => 'The office phone number',
    'merge_filter' => 'enabled',
    'displayLogic' => [
        'hide_on_name' => [
            'key' => 'displayType',
            'modes' => [
                'detail',
                'edit',
                'create',
            ],
            'params' => [
                'fieldDependencies' => [
                    'name',
                ],
                'targetDisplayType' => 'none',
                'activeOnFields' => [
                    'name' => ['Example'],
                ]
            ]
        ]
    ]
);

3. Display Logic

Within displayLogic for specific fields you can set multiple definitions. Each definition will work like an OR. For example:

    'hide_on_name' => [
        'key' => 'displayType',
        'modes' => ['detail', 'edit', 'create'],
        'params' => [
            'fieldDependencies' => [
                'name',
            ],
            'targetDisplayType' => 'none',
            'activeOnFields' => [
                'name' => ['Example']
            ]
        ]
    ],
    // OR
    'hide_on_website' => [
        'key' => 'displayType',
        'modes' => ['detail', 'edit', 'create'],
        'params' => [
            'fieldDependencies' => [
                'website',
            ],
            'targetDisplayType' => 'none',
            'activeOnFields' => [
                'website' => [ ['operator' => 'is-empty' ] ]
            ]
        ]
    ],

This means that if Name is Example the field will hide or if Website is empty then the field will also hide.

4. Properties description

Key
- The key within the named hide_on_name array is stating which logic type will be used for the following. In this case it’s displayType.
Modes
- Modes are views you would like your displayLogic to take effect on, as shown above it will be detail, edit and create. Another example of a mode that could be selected could be list for example.

Params

Field Dependencies

fieldDependencies is where you declare the field(s) that you would like your logic to depend on.

'fieldDependencies' => [
    'name',
    'website'
]

Active on Fields

activeOnFields is where you declare the field/values that trigger the change of the field to a shown/hidden field.

In the example above we have the field phone_office hide when name is Example.

If we wanted it to hide if it was either Example or another value such as User then a new value would be added like so:

'activeOnFields' => [
  'name' => ['Example', 'User'],
],

Multiple Fields

Within the activeOnFields you can add more than one field such as:

'activeOnFields' => [
  'name' => ['Example'],
  'website' => ['www.google.com', 'www.yahoo.com' ]
],

This works like an AND. If Name is Example AND Website is either www.google.com or www.yahoo.com.

When adding more fields to activeOnFields be sure to also add them to fieldDependencies

With operators

When using operators on activeonFields you can use the operator once, or multiple times within the same field to meet specific criteria.

'activeOnFields' => [
    'website' => [ ['operator' => 'is-empty'] ]
]

Multiple Operators

'activeOnFields' => [
    'employees' => [
    //AND
    [
        'operator' => 'greater-than',
        'value' => 5
    ],
    [
        'operator' => 'less-than',
        'value' => 25
    ],
    [
        'operator' => 'not-equal',
        //OR
        'values' => [15, 20]
    ],
    ['operator' => 'not-empty'],
]

In the example above if employees is:

Greater than 5
Less than 25
Not equal to 15 or 20
Has a value

Then the field will hide from the view.

An example using the code above on the Accounts Industry Field:

Using Fields as Comparison

When using operators you can use another field for the comparison. For example (within Opportunities):

'activeOnFields' => [
    'amount' => [ ['operator' => 'less-than', 'field' => 'probability'] ]
]

If amount is less than probability then the chosen field will hide from display.

You can find more information on the different operators here.

Target Display Type

targetDisplayType will either be none or show.

None will hide the field if conditions are met and Show will display the field.
