Finally got round to editing our PDF invoice template and I am having some issues. I understand basic PHP but can not see what is wrong here - I have followed all the documentation at:
<td><?php echo 'Event Date' . ':'; ?></td> <td><?php echo $custom_fields['Event Date']; ?></td>
But when generating the PDF I get a ‘Undefined Index’ error, the custom field “Event Date” definitely exists as i can prove this by printing the custom fields array to the screen, please see the attached screen shots.
Any ideas why it is unable to pull through this custom field?
