I have a form (HTML) which submits a file to a PHP script which renames the file to ZIP, stores it in a folder (random name) and then extracts that file.
The file gets uploaded. The folder is created correctly. The file gets renamed correctly.
The extraction of the zip fails.
Here is my form:
<form action="up.php" method="post" enctype="multipart/form-data" name="form1" id="form1">
Select file
<input name="ufile" type="file" id="ufile" size="50" />
<input type="submit" name="Submit" value="Upload" />
</form>
Here is the PHP script - up.php
$file_name = $HTTP_POST_FILES['ufile']['name'];
$random_digit=rand(0000,9999);
$new_file_name=$random_digit.".zip";
mkdir($random_digit, 0777, true);
$path= $random_digit.'/'.$new_file_name;
if($ufile !=none)
{
if(copy($HTTP_POST_FILES['ufile']['tmp_name'], $path))
{
echo "The upload is successful<BR/>";
echo "File Renamed to: ".$new_file_name." for processing.<BR/>";
echo "File Size :".$HTTP_POST_FILES['ufile']['size']."<BR/>";
echo "<strong><a style='color:#6A8DBC; text-decoration:none' href='".$link_address."'>Proceed to the next phase of the importation of data to the system</a></strong></br>";
}
else
{
echo "Error";
}
}
$zip = new ZipArchive;
$res = $zip->open($new_file_name);
if ($res === TRUE) {
$zip->extractTo($random_digit.'/');
$zip->close();
echo 'extraction successful';
} else {
echo 'extraction error';
}
Is it the mode of the folder which prevents extraction? As far as I can see, there is no syntax error.

As you have moved the file to $path you then need to operate on the file at $path
