Hello,

I have created a set of fields and one of those fields is a select which should auto populate with a list of blocks on the page. The issue i am running into is that it seems that the field is generated before i can get the post ID please see code below

public function tabbed_navigation_fields() {
		$block_ids = array();

		if ( ! is_admin() ) {
			global $post;
			$post_id = $post->ID;
		} else {
			if ( isset( $_GET['post'] ) ) {
				$post_id = $_GET['post'];
			} elseif ( isset( $_POST['post_ID'] ) ) {
				$post_id = $_POST['post_ID'];
			}
		}

		if ( isset( $post_id ) ) { //phpcs:ignore
			$current_post = get_post( $post_id ); //phpcs:ignore
			if ( has_blocks( $current_post->post_content ) ) {
				$blocks = parse_blocks( $current_post->post_content );
				foreach ( $blocks as $key => $block ) {
					if ( ( $block['blockName'] && 'acf/tabbed-navigation' !== $block['blockName'] ) && ( $block['attrs']['id'] ) ) {
						$name                               = str_replace( 'acf/', '', $block['blockName'] );
						$name                               = str_replace( '-', ' ', $name );
						$block_ids[ $block['attrs']['id'] ] = ucfirst( $name );
					}
				}
			}
		} else {
			$block_ids['no_id'] = 'no post id ' . $post_id;
		}

		$tabbed_navigation_fields = new \StoutLogic\AcfBuilder\FieldsBuilder(
			'tabbed_navigation_fields',
			array(
				'title' => 'Tabbed Navigation',
			)
		);
		$tabbed_navigation_fields->addRepeater(
			'tabbed_nav_links',
			array(
				'label'        => 'Links',
				'button_label' => 'Add Link',
			)
		)
		->addSelect(
			'link_block',
			array(
				'label'         => 'Block',
				'instructions'  => 'Select block to link to.',
				'choices'       => $block_ids,
				'allow_null'    => 0,
				'return_format' => 'key',
				'wrapper'       => array(
					'width' => '50',
				),
			)
		)
		->addText(
			'link_text',
			array(
				'label'    => 'Link Text',
				'required' => false,
			)
		);

		$tabbed_navigation_fields->setLocation( 'block', '==', 'acf/tabbed-navigation' );
		add_action(
			'acf/init',
			function() use ( $tabbed_navigation_fields ) {
				acf_add_local_field_group( $tabbed_navigation_fields->build() );
			}
		);
	}

So my select box always returns “no id”, but if i var_dump my array the array is complete but this seems to be running after the field is made.
