In the following examples it is assumed that you are using an HTML form field <input type="file" name="f" /> in order to upload files. For example:
HTML form for simple file upload
The following form can be used in order to test the single file upload example.
<?php // sample code from below goes here ?> <html> <head> </head> <body> <form name="fileuploadexample" method="post" enctype="multipart/form-data" action="<?php echo htmlspecialchars($_SERVER['PHP_SELF']) ?>"> <input type="file" name="f" /> <input type="submit" name="submit" value="Submit" /> </form> </body> </html>
Simple file upload
The following code looks at the request and checks if a valid file was uploaded through the form. If that is the case, the file is moved to the subdirectory uploads.
<?php
require_once "HTTP/Upload.php";
$upload = new HTTP_Upload("en");
$file = $upload->getFiles("f");
if ($file->isValid()) {
$moved = $file->moveTo('uploads/');
if (!PEAR::isError($moved)) {
echo 'File was moved to uploads/' . $file->getProp('name');
} else {
echo $moved->getMessage();
}
} elseif ($file->isMissing()) {
echo "No file was provided.";
} elseif ($file->isError()) {
echo $file->errorMsg();
}
?> Internally, HTTP_Upload_File::moveTo() calls $file->setName('safe'); which replaces special characters in the name with an underscore. You should always use $file->getProp('name') after moving to retrieve the new filename.
HTML form for multiple file upload
The following form can be used in order to test the multiple file upload example.
<?php // sample code from below goes here ?> <html> <head> </head> <body> <form name="fileuploadexample2" method="post" enctype="multipart/form-data" action="<?php echo htmlspecialchars($_SERVER['PHP_SELF']) ?>"> <input type="file" name="f1" /> <input type="file" name="f2" /> <input type="submit" name="submit" value="Submit" /> </form> </body> </html>
Multiple files, more extensive checks
Multiple files can uploaded by replacing the name of the form field (f) with f[] and creating multiple <input /> fields with this name.
<?php
$upload = new HTTP_Upload("en");
$files = $upload->getFiles();
foreach($files as $file){
if (PEAR::isError($file)) {
echo $file->getMessage();
}
if ($file->isValid()) {
$file->setName("uniq");
$dest_name = $file->moveTo("uploads/");
if (PEAR::isError($dest_name)) {
echo $dest_name->getMessage();
}
$real = $file->getProp("real");
} elseif ($file->isMissing()) {
echo "No file was provided.";
} elseif ($file->isError()) {
echo $file->errorMsg();
}
print_r($file->getProp());
}
