/* notes from Dan Potter: |
| 3 |
|
|
Sure. I changed a few other things in here too though. One is that I let |
| 4 |
|
|
you specify what the destination filename is (i.e., what is shows up as in |
| 5 |
|
|
the attachment). This is useful since in a web submission you often can't |
| 6 |
|
|
tell what the filename was supposed to be from the submission itself. I |
| 7 |
|
|
also added my own version of chunk_split because our production version of |
| 8 |
|
|
PHP doesn't have it. You can change that back or whatever though =). |
| 9 |
|
|
Finally, I added an extra "\n" before the message text gets added into the |
| 10 |
|
|
MIME output because otherwise the message text wasn't showing up. |
| 11 |

/* |
| 12 |
|
|
note: someone mentioned a command-line utility called 'mutt' that |
| 13 |
|
|
can mail attachments. |
| 14 |
|
|
*/ |
| 15 |
|
|
/* |
| 16 |
|
|
If chunk_split works on your system, change the call to my_chunk_split |
| 17 |
|
|
to chunk_split |
