Introduction to Function WP_REST_Templates_Controller::_sanitize_template_id()
The function _sanitize_template_id() in the WP_REST_Templates_Controller class is used in WordPress to ensure the validity of template identifiers. This function helps us to validate and confirm the correct and authorized identifiers in REST API requests. By using this function, we can sanitize user inputs and prevent potential errors from occurring.
WordPress developers are well aware of how much they can rely on the REST API. However, when we are capable of receiving data and sending information to our website, it is essential to ensure that this data must be valid and safe to avoid future complications.
The _sanitize_template_id() function is designed to clean template identifiers received as input. This function can include checking the type of data, template style, and other related attributes. In this way, we can prevent any contamination or invalid identifiers.
Furthermore, we will review the code for using this function and how to implement it. This code indicates how we can utilize it in our projects and how to configure template names.
$template_id = $this->_sanitize_template_id( $input_id );
if ( ! empty( $template_id ) ) {
// The template is valid, proceed.
} else {
// Error, the template is invalid.
}
Code Explanation
Code:
$template_id = $this->_sanitize_template_id( $input_id );This line of code uses the
_sanitize_template_id() function to sanitize the template identifier and stores the result in the variable $template_id.Code:
if ( ! empty( $template_id ) ) {This line checks whether
$template_id is not empty.Code:
// The template is valid, proceed.If the template is valid, we can execute the subsequent code, such as actions related to the template.
Code:
// Error, the template is invalid.If the identifier is invalid, this section of the code is executed, and we can send an error message.
