PHP Warning: Trying to access array offset on value of type bool

It is better to save all required setting options first. These errors may be caused by this.

Settings saved and server restarted. No sign of the warnings so far, however inside the plugin PDF Invoices & Packing Slips for WooCommerce v3.9.0, one of documents ( receipt ) no longer displays and shows 200: parsererror

using the “display receipt” button inside an order throws an error…

<table class=”head container receipt1″><tbody><tr><td class=”header”>

Try to check the Document -> Receipt options of PDF Invoices & Packing Slips.

And also, try to specify a Logo for your invoices.

The options are set for both the invoice and receipt, and the logo is set. The invoice document works properly, the receipt document does not.

Under PHP v8.1.29, PDF Invoices & Packing Slips for WooCommerce v3.9.0 & WooCommerce PDF Invoices Italian Add-on v0.7.4 both work

Under PHP v8.1.29, PDF Invoices & Packing Slips for WooCommerce
v3.9.0 & WooCommerce PDF Invoices Italian Add-on v0.7.6 the receipt does not work

try to deactivate and remove WooCommerce PDF Invoices Italian Add-on plugin and reinstall it.

Same results, and if I roll-back to WooCommerce PDF Invoices Italian Add-on v0.7.4 both work

maybe you are using a customized version of receipt.php ?

In this case you should copy the original corresponding invoice.php to receipt.php

Comparison of the original to the custom, there is only one difference. We removed the meta section Lines 90, 91 & 92.

<?php $description_label = __( 'SKU', 'woocommerce-pdf-italian-add-on' ); // registering alternate label translation ?>
					
<?php if( !empty( $item['sku'] ) ) : ?><dt class="sku"><?php _e( 'SKU:', 'woocommerce-pdf-italian-add-on' ); ?></dt><dd class="sku"><?php echo $item['sku']; ?></dd><?php endif; ?>
					
<?php if( !empty( $item['weight'] ) ) : ?><dt class="weight"><?php _e( 'Weight:', 'woocommerce-pdf-italian-add-on' ); ?></dt><dd class="weight"><?php echo $item['weight']; ?><?php echo get_option('woocommerce_weight_unit'); ?></dd><?php endif; ?>

Original template in the above post = the template from WooCommerce PDF Invoices Italian Add-on v0.7.4

There is only 1 template file in the folder under WooCommerce PDF Invoices Italian Add-on v0.7.6, it is named receipt.php and it has only a few lines of code.

<?php 
if(defined("WP_PLUGIN_DIR") && file_exists(WP_PLUGIN_DIR . "/woocommerce-pdf-invoices-packing-slips/templates/Simple/invoice.php")){	
include WP_PLUGIN_DIR . "/woocommerce-pdf-invoices-packing-slips/templates/Simple/invoice.php";
}

The code of receipt.php must be the same of the corresponding invoice.php.
The last invoice.php template file must be used for the receipt also.

I duplicated the last invoice.php template, named it receipt.php and uploaded it to yourtemplates. This resolved any PHP errors, HOWEVER the Receipt Number & Receipt Date fields are now empty.

OK… If I change relevant code from invoice_number() & invoice_date() to receipt_number() & receipt_date() respectively, it appears to function correctly.

Tried to display a few different orders and received this PHP Warning

PHP message: PHP Warning: Undefined array key “txtVatExemptUE” in /var/www/html/wp-content/plugins/woocommerce-pdf-invoices-italian-add-on/includes/class-wcpdf-integration3.php on line 448″

Maybe the last error happens because of some options not are saved correctly.
txtVatExemptUE is in the first page of options of WooCommerce PDF Invoice Italian Add-on

I saved the options page first, but just to double check I saved them again and ran the tests, same PHP Warning
