Pods – Custom 500+ entry list

PODS does not import content; it only imports “build” (i.e., POD structure) information, but does export both content and build information. The build (only) import/export occurs as JSON code, while content export is available in four file types, including .csv and JSON.

Third-party plugins/methods are required to accomplish content import, such as the WP All Import plugin series, which imports .csv or JSON (and other) file types.

There are also several CSV-to-JSON converters available online (or JSON-to-CSV), in case you want to maintain both content and build information in one file format; just perform a search to find them.

Incidentally, your URL link does not seem to resolve as a webpage.

Here is a function I use that might be useful in your endeavor:

<?php
/**
 * Return a term_id, creating the term from $title in $taxonomy if none exists.
 *
 * @author ??δ??? <[email protected]>
 */
function maybe_create_taxonomy_term( $title, $taxonomy ) {
	$term_id = term_exists( $title, $taxonomy );
	if ( is_array( $term_id ) ) {
		$term_id = $term_id['term_id'];
	}
	if ( empty( $term_id ) ) {
		$term_arr = wp_insert_term( $title, $taxonomy );
		$term_id = $term_arr['term_id'];
	}

	return $term_id;
}

It would be used in a plugin which calls fgetcsv() (see examples on the docs page). An appropriate place to use it might be WP_CLI::add_command() or wp_ajax_{your-action}. The first is not prone to timeout errors.
