I've been trying to imitate / reverse engineer the add attachment
feature in gmail composer. I managed to do it to say about 80% but its
giving me trouble in IE on WinXP-Sp2. I am using PHP to do the upload.
It works well on Firefox/DeerPark, but in IE, the file selected just
vanishes. You can verify it by commenting the lines marked "//IE
Trouble". Commenting those lines will remove IE specific code, except
the el.click() whick sends the Click event to the newly added file
upload input element.
Please someone help me.
