I had am error like this, dose anyone know what caused it ? It says [error] => 0 ? That should mean that there was no error but still it dosent upload. Possible file upload attack! Here is some more debugging info:Array ( [userfile] => Array ( [name] => up2.php [type] => application/octet-stream [tmp_name] => /home/venx/tmp/phpEGtTsm [error] => 0 [size] => 477 ) ) ---- Manual Page -- http://www.php.net/manual/en/features.file-upload.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+58022 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+58022&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+58022&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+58022&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+58022&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+58022&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+58022&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+58022&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+58022&report=yes Search -- http://master.php.net/manage/user-notes.php
