Hi Jim,
How PHP handle's uploaded files is quite different to normal variable
submission (which isn't mentioned in the PHP documentation very well).
$fupload won't be a variable containing the contents of the file you've
uploaded, but an array of file information in the global $_FILES array
(I don’t code PHP with global variables on).
So for:
<FORM method="POST" enctype="multipart/form-data" action="./up.php">
<input type="hidden" name="MAX_FILE_SIZE" value="1000000000">
<input type="file" name="fupload">
<INPUT type="submit">
</form>
To check if a person has selected a file, and submitted, then print the
file contents out, you would require the following PHP (for example).
<?php
//
// Check if a file has attached ('none' needed for IE compatability)
//
if ( (!empty($_FILES['fupload']['tmp_name']) ) &&
$_FILES['fupload']['tmp_name'] != 'none' )
{
$file_content = addslashes(fread(fopen($_FILES['fupload']['tmp_name'],
'r'), filesize($_FILES['fupload']['tmp_name']) )); // Read File
echo $file_content; // Echo it
}
else
{
echo 'No file was submitted';
}
?>
Btw, $_FILES['fupload']['tmp_name'] returns the name/path of the file as
it's temporarily stored on the servers FS, so having a
echo $_FILES['fupload']['tmp_name'];
would return something like
/tmp/php8329x9
Ovbiously in the $_FILES['fupload'], the 'fupload' corresponds to the
name of the form file bit in your form, so you could have multiple
uploads on the one form with $_FILES['fuploadwhatever'],
$_FILES['fupload3'] etc.. corresponding to a:
<input type="file" name="fupload3">
<input type="file" name="fuploadwhatever">
Hope this helps.
