我的文件上传表单有问题。表单上传所有文件详细信息，但不上载文件名本身。 $file变量不会与表单的其余部分一起发送，这是我的大部分问题所在。

在checkUpload中，return $file位置错误。它位于else块中，因此只有在文件类型无效时才会执行。此外，如果函数检测到错误，则需要退出，因为没有文件可以返回给调用者。
function checkUpload() //check whether everything is OK before uploading the file
{
//check for an uploaded file
if(isset($_FILES['epreuve'])){
//Validate the type
$allowed_extensions = array('application/pdf','application/pdf','application/doc','application/docx','application/ppt','application/pptx');
if(in_array($_FILES['epreuve']['type'], $allowed_extensions)){
print "Uploading files...";
//move the file over
if(move_uploaded_file($_FILES['epreuve']['tmp_name'], "../../assnet/uploads/{$_FILES['epreuve']['name']}")){
echo "<p><em>The file has been uploaded</em></p>";
$file = "{$_FILES['epreuve']['name']}";
print "$file"; //the file name is normally displayed here
} //End of move... IF
} else{ //invalid type
echo '<p class="error">Please upload a pdf, doc, docx, ppt or pptx document</p>';
exit;
}
if($_FILES['epreuve']['error'] > 0){
echo '<p class="error">The file could not be uploaded because : </strong>';
//Print a message upon the error. NB: There is no error message 5
switch($_FILES['epreuve']['error']){
case 1:
print 'The file exceeds the upload_max_file_size setting in php.ini.';
break;
case 2:
print 'The file exceeds the MAX_FILE_SIZE setting in the HTML form';
break;
case 3:
print 'The file was only partially uploaded';
break;
case 4:
print 'No file was uploaded';
break;
case 6:

break;
case 8:

break;

break;
} //End of switch
exit;

//Delete the file if it still exists
if(file_exists($_FILES['epreuve']['tmp_name']) && is_file($_FILES['epreuve']['tmp_name'])){
print 'File already exists';
unlink($_FILES['epreuve']['tmp_name']); //delete the file from the temporary folder if it still exists
}
return $file; //returns the file from where it comes from
//i.e from the addData function "[$image=checkUpload()]"
