openTBS remove image when replace not found

问题:

How do you remove the image in OpenTBS if the one you are replacing it with does not exist?

I have a bit of code that loops through and replaces pics in a table, but sometimes the client will not have the pictures. I tried leaving out the default=current tag but it shows a missing image box("This image cannot currently be displayed").

UPDATE:

I thought Skrols answer would work but I couldnt get it to work. I have an image followed by the following tag.

[field.p5;ope=changepic;from=’[val]’;adjust]

Whats tags following this would i have to use to say if the field variable p5 is not set or empty ect then remove the image.

If your first need is to not change the picture in the Docx if the target picture is a not found file, then they are two solutions:

1. First try with the latest OpenTBS version (1.7.4) because it claims to fix a bug about "default=current"
2. If it does not work, then you have to check at the PHP side if the target picture does exist using file_exists(). If it doesn't exist then change the target picture path with a new file that you are sure it does exist.

If you prefer to delete the picture box in the document if the file is missing, then you can add a TBS field that will delete the picture box depending to a global variable.

PHP:

$picok = (file_exists($the_picture)) ? 1 : 0;

[onshow;block=w:drawing;when [var.picok]=1]
