I needed a file uploader for a client a little while ago, then the client didn't want it, so
I'll share with all of you. I know I hated coding it, it was confusing (for me anyway), but I
made it fairly simple to use:
<?php
function uploader($num_of_uploads=1, $file_types_array=array("txt"),
$max_file_size=1048576, $upload_dir=""){
if(!is_numeric($max_file_size)){
$max_file_size = 1048576;
}
if(!isset($_POST["submitted"])){
$form = "<form action='".$PHP_SELF."' method='post'
enctype='multipart/form-data'>Upload files:<br /><input
type='hidden' name='submitted' value='TRUE'
id='".time()."'><input type='hidden'
name='MAX_FILE_SIZE' value='".$max_file_size."'>";
for($x=0;$x<$num_of_uploads;$x++){
$form .= "<input type='file' name='file[]'><font
color='red'>*</font><br />";
}
$form .= "<input type='submit' value='Upload'><br
/><font color='red'>*</font>Maximum file length (minus extension) is 15
characters. Anything over that will be cut to only 15 characters. Valid file type(s): ";
for($x=0;$x<count($file_types_array);$x++){
if($x<count($file_types_array)-1){
$form .= $file_types_array[$x].", ";
}else{
$form .= $file_types_array[$x].".";
}
}
$form .= "</form>";
echo($form);
}else{
foreach($_FILES["file"]["error"] as $key => $value){
if($_FILES["file"]["name"][$key]!=""){
if($value==UPLOAD_ERR_OK){
$origfilename = $_FILES["file"]["name"][$key];
$filename = explode(".", $_FILES["file"]["name"][$key]);
$filenameext = $filename[count($filename)-1];
unset($filename[count($filename)-1]);
$filename = implode(".", $filename);
$filename = substr($filename, 0, 15).".".$filenameext;
$file_ext_allow = FALSE;
for($x=0;$x<count($file_types_array);$x++){
if($filenameext==$file_types_array[$x]){
$file_ext_allow = TRUE;
}
}
if($file_ext_allow){
if($_FILES["file"]["size"][$key]<$max_file_size){
if(move_uploaded_file($_FILES["file"]["tmp_name"][$key],
$upload_dir.$filename)){
echo("File uploaded successfully. - <a
href='".$upload_dir.$filename."'
target='_blank'>".$filename."</a><br />");
}else{
echo($origfilename." was not successfully uploaded<br />");
}
}else{
echo($origfilename." was too big, not uploaded<br />");
}
}else{
echo($origfilename." had an invalid file extension, not uploaded<br
/>");
}
}else{
echo($origfilename." was not successfully uploaded<br />");
}
}
}
}
}
?>
uploader([int num_uploads [, arr file_types [, int file_size [, str upload_dir ]]]]);
num_uploads = Number of uploads to handle at once.
file_types = An array of all the file types you wish to use. The default is txt only.
file_size = The maximum file size of EACH file. A non-number will results in using the default 1mb
filesize.
upload_dir = The directory to upload to, make sure this ends with a /
This functions echo()'s the whole uploader, and submits to itself, you need not do a thing but
put uploader(); to have a simple 1 file upload with all defaults.
