if ($_POST['variable'] == '')

$uploadpath = $uploadpath . basename( $_FILES['fileup']['name']);
$sepext = explode('.', strtolower($_FILES['fileup']['name']));
$type = end($sepext);
list($width, $height) = getimagesize($_FILES['fileup']['tmp_name']);
$err = '';
if(!in_array($type, $allowtype)) $err .= 'The file: <b>'. $_FILES['fileup']['name']. '</b> not has the allowed extension type.';
if($_FILES['fileup']['size'] > $max_size*1000) $err .= '<br/>Maximum file size must be: '. $max_size. ' KB.';
if(isset($width) && isset($height) && ($width >= $alwidth || $height >= $alheight)) $err .= '<br/>The maximum Width x Height must be: '. $alwidth. ' x '. $alheight;
if($err == '') {
if(move_uploaded_file($_FILES['fileup']['tmp_name'], $uploadpath)) {
echo 'File: <b>'. basename( $_FILES['fileup']['name']). '</b> successfully uploaded:';
echo '<br/>File type: <b>'. $_FILES['fileup']['type'] .'</b>';
echo '<br />Size: <b>'. number_format($_FILES['fileup']['size']/1024, 3, '.', '') .'</b> KB';
if(isset($width) && isset($height)) echo '<br/>Image Width x Height: '. $width. ' x '. $height;
echo '<br/><br/>Image address: <b>http://'.$_SERVER['HTTP_HOST'].rtrim(dirname($_SERVER['REQUEST_URI']), '\\/').'/'.$uploadpath.'</b>';
else echo '<b>Unable to upload the file.</b>';

<div style="margin:1em auto; width:333px; text-align:center;">
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="POST" enctype="multipart/form-data">

<select name="variable" />
<option value="" selected="selected">Select a folder</option>

<form name="input" action="upload.php" method="post" onchange="this.form.submit()">

foreach($dirs as $val){
echo '<option value="'.$val.'">'.$val."</option>\n";
<input type="submit" name='submit' value="Upload" />

add the extension to

$imagetype = array( 'bmp', 'gif', 'jpg', 'jpe', 'png');
$file_type = array('txt','html');

PHP file should not be allowed to be upload in your server due to security reason.

find what is the extension of the upload and then check if it is an image or a file. If image use the image validation on your script, if it is a file validate the file accordingly.


showing file type not allowed! my changes are giving below

    $allowtype = array("$imagetype,$file_type");
    $imagetype = array( '.bmp', '.gif', '.jpg', '.jpe', '.png');
    $file_type = array('.txt','.html');

Edited by kaakka: mistake

$allowtype = array_merge($imagetype, $file_type);

Because you're using a double quote, your two variables aren't being inserted into the array. Use array_merge(), it will combine both of your arrays accurately.
