Adding a Digit Field to Forms

Overview

In this tutorial, we'll cover how to add a digit field to your forms. This method allows you to integrate digit-only inputs seamlessly into your application forms. This method takes three parameters:

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

This example shows how to add a digit field.

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

Adding a Digit Field with Maximum Value

To configure the digit field to only allow numbers up to a certain maximum value, you can chain the max() method after the digit() method. This example shows how to add a digit field that allows only numbers between 0 and 999.

// Adding a digit field with a max value of 999
$objConfig->digit('field_name', 'field_label', $required = 1)->max(3);

In this example:

• 1: Indicates the field is required.
• max(3): Restricts the input to a maximum of 3 digits, allowing values between 0 and 999.

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 digit fields are correctly initialized and integrated into your form. This example shows how to configure the add and edit fields.

// Adding your digit 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 digit fields into your forms using $objConfig->digit('field_name', 'field_label', $required = 0);. We also covered how to configure the digit field to only allow numbers up to a certain maximum value using $objConfig->digit('field_name', 'field_label', $required = 0)->max(3);.
