<html><body><form action="upload_file.php" method="post"enctype="multipart/form-data"><label for="file">Filename:</label><input type="file" name="file" id="file" /><br /><input type="submit" name="submit" value="Submit" /></form></body></html> |
upload_file.php：
<?phpif ((($_FILES["file"]["type"] == "application/vnd.ms-excel")|| ($_FILES["file"]["type"] == "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"))){if ($_FILES["file"]["error"] > 0){echo "Return Code: " . $_FILES["file"]["error"] . "<br />";}else{echo "Upload: " . $_FILES["file"]["name"] . "<br />";echo "Type: " . $_FILES["file"]["type"] . "<br />";echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />";if (file_exists("upload/" . $_FILES["file"]["name"])) { echo $_FILES["file"]["name"] . " already exists. "; }else { move_uploaded_file($_FILES["file"]["tmp_name"], "upload/" . $_FILES["file"]["name"]); echo "Stored in: " . "upload/" . $_FILES["file"]["name"]; }}}else{echo "Invalid file";}?> |
