问题
I have a document that uses mail merge to display images that are retrieved as URLs from a spreadsheet pointing to the image and the code works well.
{ INCLUDEPICTURE "{ IF TRUE { MERGEFIELD my_photo_variable_name} }" \d }
The issue I have is that when there is no image URL for the current mail merge, an error message is displayed.
Error! Filename not specified.
I am trying to engineer the code so that it just leaves the mail merge field blank like it does for text fields rather than display the error message.
I tried tried using an IF clause to determine if there is an image:
{IF { INCLUDEPICTURE "{ IF TRUE { MERGEFIELD my_photo_variable_name} }" \d }}
but that didn't work so I tried using another IF clause determine if the variable was a null value (no image):
{IF {{MERGEFIELD my_photo_variable_name} <> ""}{ INCLUDEPICTURE "{ IF TRUE {{MERGEFIELD my_photo_variable_name} " \d }}
Both of these attempts do not even show the error message let alone the image. Anyone know a way around this or am I stuck with an error message?
回答1:
Turns out I was very close, incorrect curly bracket placement was what was causing my attempt to fail:
{IF {MERGEFIELD my_photo_variable_name} <> "" {INCLUDEPICTURE "{IF TRUE {MERGEFIELD my_photo_variable_name}}" \d} "Text to display if no picture available"}
Which translates as:
If there is no value for the image my_photo_variable_name, include the image in the mail merge.
If there is no value i.e no image, then display custom text Text to display if no picture available.
