Get upload file name with upload file in image

Hello,

Unfortunately, there is no default function to get the file name. You can try to accomplish the task by adding a custom PHP filter to your themes functions.php or as a PHP snippet: https://codefile.io/f/Uip5ymJdJe

After the snippet is added, it must be possible to use the shortcode to output the filename:

[e2pdf-format-output explode="," explode_filter="array_filter" filter="trim" output="{0}" get_file_name="true"]{Upload:1},{Upload:2},{Upload:3},{Upload:4}[/e2pdf-format-output]

If under "image" caption you mean the data added to the file in WordPress directly - you can try to modify the code to get the attachment ID by the URL and output the caption from the attachment but unfortunately, we can't provide you with that code example directly.
