Snippet works in functions.php but not in Snippets plugin

Resolved

(@beniellis)

I have a snippet for customizing my rss feed. It works fine when it is in my functions.php file, but breaks my website — the white screen of “oh s**t!” — when I add it via the Code Snippet plugin. Snippets are a bit beyond my comfort zone, so I don’t understand why they work in the functions file, but not via the plugin.

Any thoughts how to make this work? This is the code I used to create the snippet:

// add custom fields to rss feed

    function add_feed_content($content) {
    global $wp_query;
    $postid = $wp_query->post->ID;

    $city = get_post_meta($postid, 'property_city', true);
    if(is_feed()) {
    if($city !== '') {
    $content = $content."<div><h3>".$city." in ""</h3></div>
    ";
    }
    else {
    $content = $content;
    }
    }

    $area = get_post_meta($postid, 'property_area', true);
    if(is_feed()) {
    if($area !== '') {
    $content = $content."<div><h3>".$area."</h3></div>
    ";
    }
    else {
    $content = $content;
    }
    }

    return $content;
    }
    add_filter('the_excerpt_rss', 'add_feed_content');
    add_filter('the_content', 'add_feed_content');

// edit excerpt to 45 words
    function custom_excerpt_length( $length ) {
	return 45;
}
add_filter( 'excerpt_length', 'custom_excerpt_length', 999 );

// add featured image to rss feed
function featuredtoRSS($content) {
global $post;
if ( has_post_thumbnail( $post->ID ) ){
$content = '' . get_the_post_thumbnail( $post->ID, 'medium', array( 'style' => 'float:left; margin:0 15px 15px 0;' ) ) . '' . $content;
}
return $content;
}

add_filter('the_excerpt_rss', 'featuredtoRSS');
add_filter('the_content_feed', 'featuredtoRSS');

// ----- end rss custom fields ------------------

Hi
(Sorry i’m french and my english is very bad) 🙂

I have the same “issue” with a (maybe too complex ?) code that use with WC Vendors plugin (for remove all” Sold by)

// Put this in your themes functions.php
// Remove all existing actions and filters
remove_action( 'woocommerce_after_shop_loop_item', 	array( 'WCV_Vendor_Shop', 'template_loop_sold_by'), 9, 2);
remove_filter( 'woocommerce_get_item_data', 		array( 'WCV_Vendor_Cart', 'sold_by' ), 10, 2 );
remove_action( 'woocommerce_product_meta_start', 	array( 'WCV_Vendor_Cart', 'sold_by_meta' ), 10, 2 );
remove_filter( 'woocommerce_order_product_title', 	array( 'WCV_Emails', 'show_vendor_in_email' ), 10, 2 );
remove_action( 'woocommerce_add_order_item_meta', 	array( 'WCV_Vendor_Shop', 'add_vendor_to_order_item_meta'), 10, 2 );
remove_action( 'woocommerce_after_shop_loop_item',  array( $wcvendors_pro->wcvendors_pro_store_controller, 'loop_sold_by' ), 8  );
remove_action( 'woocommerce_product_meta_start',  	array( $wcvendors_pro->wcvendors_pro_store_controller, 'product_sold_by' ), 8 );
remove_filter( 'woocommerce_get_item_data',  		array( $wcvendors_pro->wcvendors_pro_store_controller, 'cart_sold_by' ), 8, 2 );
// Hook into the product loop
add_action( 'woocommerce_after_shop_loop_item', 'custom_loop_sold_by', 9 );
function custom_loop_sold_by($product_id) {

	$vendor_id = WCV_Vendors::get_vendor_from_product( $product_id );

	if ( WCV_Vendors::is_vendor( $vendor_id) ) { 

		$shop_url 	=  '';
		$store_id 	= WCVendors_Pro_Vendor_Controller::get_vendor_store_id( $vendor_id );
		$sold_by 		= apply_filters( 'wcv_loop_sold_by',

		echo $sold_by[ 'wrapper_start' ];
		echo $sold_by[ 'title' ] .'<a href="'.$sold_by[ 'shop_url' ].'">'. $sold_by[ 'shop_name' ] .'</a>';
		echo $sold_by[ 'wrapper_end' ];
	}
} //custom_loop_sold_by()
// Hook into the cart data
add_filter( 'woocommerce_get_item_data', 'custom_cart_sold_by', 10, 2 );
function custom_cart_sold_by( $values, $cart_item ) {
	$vendor_id = $cart_item[ 'data' ]->post->post_author;
	if ( WCV_Vendors::is_vendor( $vendor_id ) ) {
		$is_vendor 	= WCV_Vendors::is_vendor( $vendor_id );
		$store_id 	= $is_vendor ? WCVendors_Pro_Vendor_Controller::get_vendor_store_id( $vendor_id ) : 0;
		$shop_url 	= ( $store_id 	!= 0 ) ? get_the_permalink( $store_id ) : '';
		$sold_by 	= '';
		if ( $is_vendor ) {
			$sold_by = sprintf( '<a href="%s" target="_TOP">%s</a>', $shop_url, WCV_Vendors::get_vendor_sold_by( $vendor_id ) );
		} else {
			$sold_by =  get_bloginfo( 'name' );
		}

		$values[] = array(
			'name' => apply_filters( 'wcv_cart_sold_by', __( 'Sold by', 'wcvendors-pro' ) ),
			'display' => $sold_by,
		);
		return $values;
	}
	return $values;
} // custom_cart_sold_by()
// Hook into the single product meta template
add_action( 'woocommerce_product_meta_start', 'custom_product_sold_by_meta', 10, 2 );
function custom_product_sold_by_meta() {
	$vendor_id = get_the_author_meta( 'ID' );

	if ( WCV_Vendors::is_vendor( $vendor_id ) ) {
		$shop_url 	=  '';
		$store_id 	= WCVendors_Pro_Vendor_Controller::get_vendor_store_id( $vendor_id );
		$sold_by 		=  array(
				'vendor_id'			=> $vendor_id,
				'shop_url' 			=> get_the_permalink( $store_id ),
				'shop_name'			=> WCV_Vendors::get_vendor_sold_by( $vendor_id ),
				'wrapper_start'		=> '<small class="wcv_sold_by_in_loop">',
				'wrapper_end'		=> '</small><br />',

		);
		echo $sold_by[ 'wrapper_start' ];
		echo $sold_by[ 'title' ] .'<a href="'.$sold_by[ 'shop_url' ].'">'. $sold_by[ 'shop_name' ] .'</a>';
		echo $sold_by[ 'wrapper_end' ];
	}
} // custom_product_sold_by_meta()

Best regards,

Your snippet fails to save because there is an error. On like 10, you have an extra "" double quote mark. Remove this so the line 10 looks like this:

$content = $content."<div><h3>".$city." in </h3></div>

MoiMM:

Your problem is actually a bit different. It’s because remove_action() calls don’t always work when places directly before snippets, as snippets run before functions.php code. Try using this code instead:

// Remove all existing actions and filters
add_action( 'init', function () {
	remove_action( 'woocommerce_after_shop_loop_item', 	array( 'WCV_Vendor_Shop', 'template_loop_sold_by'), 9, 2);
	remove_filter( 'woocommerce_get_item_data', 		array( 'WCV_Vendor_Cart', 'sold_by' ), 10, 2 );
	remove_action( 'woocommerce_product_meta_start', 	array( 'WCV_Vendor_Cart', 'sold_by_meta' ), 10, 2 );
	remove_filter( 'woocommerce_order_product_title', 	array( 'WCV_Emails', 'show_vendor_in_email' ), 10, 2 );
	remove_action( 'woocommerce_add_order_item_meta', 	array( 'WCV_Vendor_Shop', 'add_vendor_to_order_item_meta'), 10, 2 );
	remove_action( 'woocommerce_after_shop_loop_item',  array( $wcvendors_pro->wcvendors_pro_store_controller, 'loop_sold_by' ), 8  );
	remove_action( 'woocommerce_product_meta_start',  	array( $wcvendors_pro->wcvendors_pro_store_controller, 'product_sold_by' ), 8 );
	remove_filter( 'woocommerce_get_item_data',  		array( $wcvendors_pro->wcvendors_pro_store_controller, 'cart_sold_by' ), 8, 2 );
} );

// Hook into the product loop

The rest of the code underneath `
// Hook into the product loop` is the same.
