Text

Description

The text field type creates a single-line text input field in the admin panel, allowing users to enter free-form text. It is rendered as an HTML <input type="text"> element styled with Bootstrap’s form-control class. This field is ideal for capturing strings such as usernames, titles, or other short text data.

Available Options

Parameter Type Description Required Default
name String The name of the field, used as the identifier and default label if label is not provided. Yes –
type String The field type. Must be set to text. Yes –
label String The display label for the text field. If not provided, the name is used. No name
placeholder String A hint displayed in the field when it is empty, guiding the user on expected input. No name
default String/Boolean The default value of the text field. If set to false, the field will be empty by default. No false
class String Additional CSS classes to apply to the text input for custom styling or JavaScript targeting. No –
help String A help message displayed in a sidebar or tooltip when the user clicks the info icon next to the field. No –
required Boolean If true, the field is marked as required, adding the HTML required attribute. No false


Note: The text field is stored in the settings array as a sanitized string. The value is sanitized using WordPress’s sanitize_text_field function to ensure security.

Example

Below is an example of how to define a text field in the $fields array for the Reusable Admin Panel settings class.

$this->fields = array(
    'general' => array(
        array(
            'name'    => __('Username', 'your-plugin-slug'),
            'type'    => 'text',
            'label'   => __('Your Username', 'your-plugin-slug'),
            'default' => '',
            'class'   => 'username-input',
            'help'    => __('Enter a username.', 'your-plugin-slug'),
            'required' => true
        )
    )
);

This configuration will create a text field labeled “Your Username” under the “general” section. It will be empty by default, have the CSS class username-input, include a help message, and be marked as required.

Usage Notes

  • The text field uses WordPress’s sanitize_text_field for sanitization, removing unsafe characters and ensuring the input is safe for storage.
  • The field’s ID is automatically generated as {section}-{name}, where name is sanitized using sanitize_title.
  • The field is styled using Bootstrap’s form-control class. Custom styles can be applied via the class parameter.
  • The required attribute triggers browser validation, but server-side validation should also be implemented if critical.
  • To retrieve the value of a text field, use the get_option method, e.g., $this->get_option('general', 'username').
