So I have 4 pages. They are very simple.
index.php (WORKS)
<html>
<form action="upload.php" method="POST" enctype="multipart/form-data">
<input type="file" name="file"><br />
<input type="submit" value="Now upload it!">
</form>
</html>
upload.php (WORKS)
<?php
if ($_FILES["file"]["error"] > 0)
{
echo "Error: " . $_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 "Stored in: " . $_FILES["file"]["tmp_name"];
echo 'Are you sure you want to continue saving this file';
echo '<a href="yes.php">Yes, continue</a>
<br />
<br />
<a href="no.php">No thanks</a>'
}
?>
no.php (WORKS)
<?php
echo 'Thanks anyway';
?>
yes.php (ERROR)
<?php
if ($_FILES["file"]["error"] > 0)
{
echo "Error: " . $_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 "Stored in: " . $_FILES["file"]["tmp_name"];
echo 'We will now save this document:';
//Save document code
}
?>
Output of yes:
Notice: Undefined index: file in /home/public_html/test/yes.php on line 2 Invalid file
We will now save this document:?
As you can see I never save it. But I would like to save it in the yes.php page. Is it still possible to retrieve that original doc that was uploaded? Thanks in advance.
Uploaded files are only available for a single PHP instance/request cycle.
Uploaded files are stored in the temp directory. If they’re still there when the script finishes executing, PHP will delete them assuming you didn’t need them.
If you want to persist the file, you’ll have to move it elsewhere in the same request that the file was uploaded.
