Custom config parameters

In this article it will be shown how to add custom config parameters and how to make them available on the administration panel.

In the example it's supposed that your module is named MyModule. Replace MyModule and my-module with your real module name.

1. Metadata entityDefs > settings

Create a file custom/Espo/Modules/MyModule/Resources/metadata/entityDefs/Settings.json:

{
    "fields": {
        "myParameter": {
            "type": "enum",
            "options": ["Option 1", "Option 2"],
            "tooltip": true
        }
    }
}

2. Metadata app > config

Create a file custom/Espo/Modules/MyModule/Resources/metadata/app/config.json:

{
    "params": {
        "myParameter": {
            "level": "admin"
        }
    }
}

The level parameter defines availability of the config parameter in the front-end.

• default – available for logged-in users (applied by default);
• global – available even before logging in;
• system – never available;
• internal – never available for read, admin can write (useful for passwords, secrets; recommended to use the password field type) (as of v7.3);
• admin – available only for admin (read and write);
• superAdmin – available only for super-admin (read and write).

The readOnly parameter disables the ability to change a parameter value for admin users.

3. Metadata app > adminPanel

Create a file custom/Espo/Modules/MyModule/Resources/metadata/app/adminPanel.json:

{
    "myPanel": {
        "label": "My Panel",
        "itemList": [
            {
                "url": "#Admin/mySettings",
                "label": "My Settings",
                "iconClass": "fas fa-cog",
                "description": "myDescription",
                "recordView": "my-module:views/admin/my-settings"
            }
        ],
        "order": 101
    }
}

4. Language files

Create a file custom/Espo/Modules/MyModule/Resources/i18n/en_US/Admin.json:

{
    "keywords": {
        "myPanel": "some search keyword,another search keyword"
    },
    "descriptions": {
        "myDescription": "Description text."
    },
    "labels": {
        "My Settings": "My Settings",
        "My Panel": "My Panel"
    }
}

Create a file custom/Espo/Modules/MyModule/Resources/i18n/en_US/Settings.json:

{
    "fields": {
        "myParameter": "My Parameter"
    },
    "tooltips": {
        "myParameter": "My parameter tooltip text. Markdown supported."
    },
    "options": {
        "myParameter": {
            "Option 1": "Option 1",
            "Option 2": "Option 2"
        }
    }
}

5. View

Create a file client/custom/modules/my-module/src/views/admin/my-settings.js:

define('my-module:views/admin/my-settings', ['views/settings/record/edit'], function (Dep) {

    return Dep.extend({

        detailLayout: [
            {
                rows: [
                    [
                        {
                            name: 'myParameter'
                        },
                        false
                    ]
                ]
            }
        ],

        // Dynamic logic can de defined.
        dynamicLogicDefs: {},

        setup: function () {
            Dep.prototype.setup.call(this);

            // Some custom logic can be written here.
        },
    });
});

6. Final step

Clear cache.

The parameter value now can be read in the back-end:

<?php
/** @var \Espo\Core\Utils\Config $config */
$config->get('myParameter');
