Notes set in the upload_max_filesize field in your php.ini file that defaults to 2MB. The MAX_FILE_SIZE
field is obeyed at the browser’s discretion, so you should rely on the php.ini setting to cap
unreasonable uploads. After the MAX_FILE_SIZE field has been entered, you’re ready to add
the upload field itself. This is simply an INPUT element with a TYPE argument of “file”. You
can give it any name you want. Listing 13 brings all this together into an HTML upload form.

Listing 13 A Simple File Upload Form

<?php
$uploaddir = ‘/var/www/uploads/’;

$uploadfile = $uploaddir . basename($_FILES[‘userfile’][‘name’]);
echo “<p>”;

if (move_uploaded_file($_FILES[‘userfile’][‘tmp_name’], $uploadfile))

{
echo “File is valid, and was successfully uploaded.\n”;
}

else

{

echo “Upload failed”;

}
echo “</p>”;

echo ‘<pre>’;
echo ‘Here is some more debugging info:’;

print_r($_FILES);

print “</pre>”;
?>

9.10 Summary

• The more standard HTML you can leave in your pages, the easier they are for designers
and page builders to amend without reference to you.

• A hidden field behaves exactly the same as a text field, except that the user cannot see it
unless he views the HTML source of the document that contains it.

• After making any changes to php.ini on any platform, you must restart the web server
process for the changes to take effect.
