Image not found or type unknown

Hello @dynamek

Could you try to enable the HTML output under the Status tab and inspect the image URL?

Let me know what you find.

When showing using html output the image shows fine.

Output is

<p class="wcpa_image"><img style="width:90px" src="https://www.atlantic-shore.co.uk/wp-content/uploads/2021/01/Pink-Polka-Dot.png" width="90">Pink<span class="wcpa_cart_price">(<span class="wcpa_price"><span class="woocommerce-Price-currencySymbol">￡</span><span class="price_value">1.00</span></span>)</span></p>

Hi @dynamek

Could you provide us the information below?

• A screenshot of the ‘Write Permissions’ panel in the Status tab of the PDF invoice settings
• The exact code you used for the image URL

Write permissions sent by email.

I’m not sure what you want for the ‘Exact code used for image URL’. I am using the Woocommerce Custom Product Addons plugin so I’m just adding an image to their form builder.

Image URL I am adding is what automatically would be added in media admin – https://www.atlantic-shore.co.uk/wp-content/uploads/2021/01/Blue-Polka-Dot.png for example

Hi @dynamek

If this is a custom template, how are you pulling the “Woocommerce Custom Product Addons” data?

I haven’t changed anything from the Simple Template other than added a returns address. So I’m guessing it is using the standard meta code within the Simple Template?

The html shows inside
<span class="item-meta"><ul class="wc-item-meta"><li>

which is
<span class="item-meta"><?php echo $item['meta']; ?></span>

Hi @dynamek

Could you please try the code snippet below?

add_filter( 'wpo_wcpdf_get_html', function ( $html, $document ) {
	if ( !class_exists('DOMDocument') || stripos( $html, "</html>" ) === false ) {
		return $html;
	}
	$dom = new DOMDocument();
	$dom->loadHTML( $html );

	foreach ( $dom->getElementsByTagName( 'img' ) as $image ) {
		$image->setAttribute( 'src', str_replace( trailingslashit( content_url() ), trailingslashit( WP_CONTENT_DIR ), $image->getAttribute( 'src' ) ) );		
	}

	return $dom->saveHTML($dom);
}, 10, 2);

If you never worked with actions/filters please read this documentation page: How to use filters

Thanks that’s looking like it will work now!
Styling isn’t ideal but will do if there’s nothing that can be done.

Hi @dynamek

Glad it worked!

Styling can be done using custom styles.

Ah great, thanks! ??

Just to say I’m getting PHP warnings from this code:

mod_fcgid: stderr: PHP Warning: DOMDocument::loadHTML(): Tag bdi invalid in Entity

Do you have a fix?

Constant apache errors from this code you suggested… and could be causing issues with another plugin. Fix please!

mod_fcgid: stderr: PHP Warning: DOMDocument::loadHTML(): Tag bdi invalid in Entity, line: 391 in /functions.php on line 359 Apache error

Also we to have a problem where the PDF does show the images correctly but they don’t print out – they print the square crossed box. Help!
