Example how to use the wppfm_feed_item_value filter for woocommerce product feed manager

Alter feed items

<?php

function alter_feed_item( $attributes, $feed_id, $product_id ) {

	// The $attributes variable is an array that contains all the product data that goes into the feed. Each item
	// can be accessed by it's feed key. So if in the feed file an item has a key like 'description', you
	// can access that specific item by $attributes['description'].
	// The $feed_id (string) makes it possible to only edit a specific feed. You can find the id of a feed in the
	// url of the Feed Editor, right after id=.
	// The $product_id (string) makes it possible to select a specific product id that you want to filter.
	
	// The following example only changes the data of a feed with ID 7
	if( $feed_id === '7' ) {
		
		// this line changes the title data and removes the " <prompt> " string
		$attributes['title'] = str_replace( " <prompt> ", "", $attributes['title'] );
		
		// this lines puts the text Dollar behind the price data
		$attributes['price'] = $attributes['price'] . " Dollar";
		
		// And you can be more specific by using the $product_id
		if ( $product_id === '13' ) {
			$attributes['availability'] = 'unknown';
		}
	}
	
	// or you can just make a simple change that will influence all feeds
	// If you have shortcodes in your product description you can remove them with het next code
	// Remove WordPress shortcodes from Description
	$attributes['description'] = strip_shortcodes( $attributes['description'] );
	
	// If you use Visual Composer markup in your product descrioptions you can remove Visual Composer markup with the next code.
	$attributes['description'] = preg_replace("/\[(\/*)?vc_(.*?)\]/", '', $attributes['description'] );
	
	// To remove Divi markup in your product description use the below preg replace.
	$attributes['description'] = preg_replace("/\[\/?et_pb.*?\]/", '', $attributes['description'] );
	
	// IMPORTANT! Always return the $attributes
	return $attributes;
}

add_filter( 'wppfm_feed_item_value', 'alter_feed_item', 10, 3 );

@Auke1810 does this overwrite settings from within plugin? (Hopefully)

If you’re not familiar with using filters in your wp-admin, the best and easiest way to do this is by using the “My Custom Functions” plugin (https://wordpress.org/plugins/my-custom-functions/). And here you can find a great video explaining the use if this plugin https://www.youtube.com/watch?v=R8dZ-mSRNOg.

Not fully understand what your asking. The function alters the feed and feed settings after the settings in the plugin. So if you set the price in a certain way in the feed settings this filter will alter it again.
