Including a select drop down using data from a database field

Overview

In this tutorial, we'll cover how to  populate a select dropdown with options from a database using $objConfig->select('field_name', 'field_label', $required = 0)->childDatabase('table_name', 'id_field', 'value_field');. This method takes three parameters:

• field_name: The name attribute for the dropdown.
• field_label: The label that will be displayed alongside the dropdown.
• $required: An optional parameter (default is 0) that specifies whether the input is required (1) or not (0).

Example Code

 // Adding a required select dropdown field
$objConfig->select('field_name', 'field_label', $required = 0); 

Populating the Dropdown with Data from a Database field

To populate the select dropdown with options from a database, you can chain the childDatabase method after the select method. This example shows how to add a select dropdown field that reads its options from a database.

// Populating the dropdown with options from the database
$objConfig->select('field_name', 'field_label', $required = 0)->childDatabase('table_name', 'id_field', 'value_field'); 

In this example:

• 'table_name': The name of the database table containing the options.
• 'id_field': The field in the table that contains the unique identifier for each option.
• 'value_field': The field in the table that contains the value to be displayed in the dropdown.

Configuration in Your Application

For the configuration to work properly, it's important to include the 'field_name'  amongst the `addFields` and `editFields`. This ensures that the fields are correctly initialized and integrated into your form. This example shows how to configure the add and edit fields.

// Adding your field to the add and edit forms
$objConfig->addFields(array('field_name'));
$objConfig->editFields(array('field_name'));

Conclusion

By following these steps, you can easily integrate select dropdown fields into your PHP forms using $objConfig->select('field_name', 'field_label', $required = 0);.
