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.

Example
Below is an example of how to define a text field in the $fields array for the Reusable Admin Panel settings class.
$this->fields = array(
'general' => array(
array(
'name' => __('Username', 'your-plugin-slug'),
'type' => 'text',
'label' => __('Your Username', 'your-plugin-slug'),
'description' => __('Enter a username.', 'your-plugin-slug'),
'default' => '',
'class' => 'username-input',
'help' => __('Enter a username.', 'your-plugin-slug'),
'required' => true
)
)
);
This configuration will create a text field labeled “Your Username” under the “general” section. It will be empty by default, have the CSS class username-input, include a help message, and be marked as required.
Usage Notes
- The
textfield uses WordPress’ssanitize_text_fieldfor sanitization, removing unsafe characters and ensuring the input is safe for storage. - The field’s ID is automatically generated as
{section}-{name}, wherenameis sanitized usingsanitize_title. - The field is styled using Bootstrap’s
form-controlclass. Custom styles can be applied via theclassparameter. - The
requiredattribute triggers browser validation, but server-side validation should also be implemented if critical. - To retrieve the value of a text field, use the
get_optionmethod, e.g.,$this->get_option('general', 'username').
