How to set value of <INPUT type=file...> element programmatically?

Recommended Posts



I need to simulate send POST data ( - file upload) as it was submitted in Browser


echo "<form enctype=\"multipart/form-data\" action=\"uploader.php\" method=\"POST\" name=\"f\">";

echo "<input name=\"uploadedfile\" type=\"file\">";

echo "<input name=\"f\" type=\"submit\" value=\"up\"></form>";


#include <IE.au3>

$oIE = _IECreate ("")

$oForm = _IEFormGetObjByName ($oIE, "f")

$oQuery = _IEFormElementGetObjByName ($oForm, "uploadedfile")

_IEFormElementSetValue ($oQuery, "c:\b.png")

_IEFormSubmit ($oForm)


--> IE.au3 Error from function _IEFormElementSetValue, $_IEStatus_InvalidObjectType (Browser securuty prevents SetValue of TYPE=FILE)

See the Remarks for _IEFormElementSetValue for a workaround.

SciTe Debug mode - it's magic: #AutoIt3Wrapper_run_debug_mode=Y Doesn't work needs to be ripped out of the troubleshooting lexicon. It means that what you tried did not produce the results you expected. It begs the questions 1) what did you try?, 2) what did you expect? and 3) what happened instead?
