show products in preview

[gregoriopellegrino]

Hi, I'm setting-up this plugin. I have some problems in showing the products in preview mode. I've created a function in my theme's functions.php file.

In preview mode wcng_get_value( $block_id, 'product', 'product_id', 0 ) returns always 0; instead if I publish the newsletter it returns the correct product_id.

Can you elaborate more about "in preview mode"? How can I replicate that issue?

[gregoriopellegrino]

I mean when the newsletter is editable in (the post is in draft state).

Can you share the screenshot? I seem not to have this kind of issue. Also, can you elaborate more on I've created a function in my theme's functions.php file.? A snippet of what you're doing will really help.

Sure. Here it is the screenshot.

Here the function of my snippet:

function effata_product_block( $block_id = '', $product_image_size = 'medium' ){

    // Get product data
    $product_id = wcng_get_value( $block_id, 'product', 'product_id', 0 );
    /*$permalink  = wcng_permalink( wcng_get_value( $block_id, 'product', 'permalink', '#' ) );
    $title      = wcng_get_value( $block_id, 'product', 'title', __( 'Product Name', 'woocommerce-newsletter-generator' ) );
    $price      = wcng_get_value( $block_id, 'product', 'price', '-' );
    $image      = wcng_get_value( $block_id, 'product', 'image', WC_NEWSLETTER_GENERATOR_URL . 'assets/default-product-image.png' );*/

    // Print wrapper for admin
    if( wcng_is_previewing() && wcng_current_user_can_edit_newsletter() ){
        echo "<div class='edit-content-block' data-type='product' data-id='$block_id' data-product-id='$product_id' data-product-image-size='$product_image_size'>";
        echo "<button class='toggle-edit-block'>". __( 'Edit', 'woocommerce-newsletter-generator' ) ."</button>";

        if($product_id == 0) {
    ?>
        <table>
            <tr>
                <td>
                    segnaposto per prodotto <?php echo $block_id; ?>

    if($product_id != 0) {
        $product = new WC_Product( $product_id );

                            $new_height = (int) ($image_metadata["sizes"]["medium"]["height"] * $new_width / $image_metadata["sizes"]["medium"]["width"]);
