Show cart item data

Hey Saravana!

I thank you for getting back to me this quick, I’m really really grateful!

When using your updated function I first got an error saying “Data has already been sent to output” after a quick google I found that using the ob_start/ob_clean could possibly help me solve this problem so I tried adding it to the function. This got the Pdf to be outputted again but it still says “Position: Array”

I tried to do some troubleshooting and maybe this information can help:
I had two items in the cart, one without any custom field and one with the text:Random but in the output error it said “RandomRandomData has already been sent to output” notice that it repeats 2 times even though I only have one item with the custom field. I then tried adding a third item also without any input in the custom field and the error returned the Random Text three times. This tells me we’re getting the value of the field but that maybe the foreach is not needed and the pdf generator is already running the function for each item in the cart? I might be wrong since like I said my knowledge of php is very limited but I hope this might make some sence to you.

I’ve been trying to find a solution by myself for a while but I’m stuck and I’m really sorry to be taking up your time. If it’s out of your scope of support I understand but if you would be willing to give it another try with this new information I wouldn’t be able to thank you enough.

This is the code from you with the ob_start/clean added to it:

function show_text_pdf ($html, $id) {
ob_start();	
 	if( count( WC()->cart->get_cart() ) > 0 ) {
    	foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
        	if( isset( $cart_item[ "wccpf_fritext" ] ) ) {
				/**
				 * 
				 * This $field has user value as well as some additional meta for other functionalities 
				 * So we cannot use it as a whole
				 * 
				 * */
				$field = $cart_item[ "wccpf_fritext" ];
				/* The user_val property inside $field has the actual user value */
				echo isset($field["user_val"]) ? $field["user_val"] : "";
            	
        	}
    	}       
	}
	$html = 'Position: ' . $cart_item;
	return $html;
ob_clean();
}
add_filter( 'woocommerce_pdf_catalog_before_product_information', 'show_text_pdf', 10, 2);

This is the original example i tried to incorperate your snippet in:

add_filter( 'woocommerce_pdf_catalog_before_product_information', 'show_case_pack_in_pdf', 10, 2);
 function show_case_pack_in_pdf ($html, $id) {
 	
 	$product = wc_get_product($id);
 	$pid= $product->get_id();

 	$case_pack = get_post_meta($pid,'case_pack',true); 

	$html = 'Case Pack: ' . $case_pack;

	return $html;
 }
