Using (array() in custom conditional functions - php

Question

How can I create an array of multiple endpoint for the below custom conditional code?
function is_single_with_endpoint( $endpoint ) {
global $wp_query;
if ( ! isset( $endpoint ) && ! empty( $endpoint ) ) {
return false;
}
if ( array_key_exists( $endpoint, $wp_query->query_vars ) ) {
return true;
} else {
return false;
}
}
This will work is I use
if ( ! is_single_with_endpoint('overview') && ! is_single_with_endpoint('analytics') ) {
but not as
if ( ! is_single_with_endpoint(array('overview','analytics')) ){

Answer 1

We can just step through the array of inputs and check each one for a failure. If none of them produce failure, then it passes at the end.
function is_single_with_endpoint($endpoints) {
global $wp_query;
// Iterate through set (can be set of one)
foreach ((array)$endpoints AS $endpoint) {
if (empty($endpoint)) {
return false;
}
if (!array_key_exists($endpoint, $wp_query->query_vars)) {
return false;
}
}
// Didn't fail, so it passes
return true;
}

I would do this, instead:
function is_single_with_endpoint($endpoint = null){
global $wp_query;
if($endpoint === null){
return false;
}
if(is_array($endpoint)){
foreach($endpoint as $k => $v){
if(!array_key_exists($k, $wp_query->query_vars)){
return false;
}
}
}
else{
if(!array_key_exists($endpoint)){
return false;
}
}
return true;
}
