method_check_array_key()

method_check_array_key( $item, $key )

Checks whether an array key exists and has a non‑empty value.

Description

A safe, concise way to verify that $item is an array, that $key exists within it, and that the value at that key is not empty. This is the most frequently used utility function in Method — it appears in virtually every block render callback and helper function.

Parameters

$item (mixed) :
The variable to check. If not an array, returns false.

$key (string|int) :
The array key to check.

Return

(bool) true if $item is an array, $key exists, and $item[$key] is non‑empty. false otherwise.

Source

function method_check_array_key( $item, $key ) {
    return is_array( $item ) && isset( $item[ $key ] ) && ! empty( $item[ $key ] );
}

function method_check_array_key( $item, $key ) {
    return is_array( $item ) && isset( $item[ $key ] ) && ! empty( $item[ $key ] );
}

File: lib/helper-functions.php

Usage

if ( method_check_array_key( $block_attributes, 'link' ) ) {
    $url = $block_attributes['link']['url'];
}

if ( method_check_array_key( $options, 'bc_home' ) ) {
    // Include home link in breadcrumb
}

if ( method_check_array_key( $block_attributes, 'link' ) ) {
    $url = $block_attributes['link']['url'];
}

if ( method_check_array_key( $options, 'bc_home' ) ) {
    // Include home link in breadcrumb
}

Notes

• Replaces the deprecated method_check_key() for array contexts.
• Uses empty() internally, so values like 0, '', null, false, and [] all return false.
