Upload script

GsXtAsY · August 19, 2008

I have 3 total files so far and what i am wanting to do is instead of uploading the files into the main directory where the .php files are stored how would i go about having the files upload into a "upload" folder? Also I want to be able to display the files uploaded on one page without looking like a directory listing.

Here is the code:

<form name="form1" method="post" action="uploadForm2.php">
  <p>Enter the amount of boxes you will need below. Max = 9.</p>
  <p>
    <input name="uploadNeed" type="text" id="uploadNeed" maxlength="1">
  </p>
  <p>
    <input type="submit" name="Submit" value="Submit">
  </p>
</form>

<form name="form1" enctype="multipart/form-data" method="post" action="processFiles.php">
  <p>
  <?
  // start of dynamic form
  $uploadNeed = $_POST['uploadNeed'];
  for($x=0;$x<$uploadNeed;$x++){
  ?>
    <input name="uploadFile<? echo $x;?>" type="file" id="uploadFile<? echo $x;?>">
  </p>
  <?
  // end of for loop
  }
  ?>
  <p><input name="uploadNeed" type="hidden" value="<? echo $uploadNeed;?>">
    <input type="submit" name="Submit" value="Submit">
  </p>
</form>

<?
$uploadNeed = $_POST['uploadNeed'];
// start for loop
for($x=0;$x<$uploadNeed;$x++){
$file_name = $_FILES['uploadFile'. $x]['name'];
// strip file_name of slashes
$file_name = stripslashes($file_name);
$file_name = str_replace("'","",$file_name);
$copy = copy($_FILES['uploadFile'. $x]['tmp_name'],$file_name);
// check if successfully copied
if($copy){
echo "$file_name | uploaded sucessfully!<br>";
}else{
echo "$file_name | could not be uploaded!<br>";
}
} // end of loop
?>

here is an upload script I have written:

$sql = mysql_query("SELECT * FROM $TBL-NAME") or die(mysql_error());

				$results = mysql_fetch_array($sql);

				$upload_dir = "PATH-TO-UPLOAD-DIR";
				$upload_name = $_FILES['uploadedfile']['name'];

				$target_path = "uploads/";

				$target_path = $target_path . basename($_FILES['uploadedfile']['name']); 

				if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {

					$sql = mysql_query("INSERT INTO table_name (column1, column2, column3) VALUES ('$column1', '$column2', '$column3')") or die(mysql_error());

					echo '<h2>Upload successful!</h2>';
					echo '<p>Thanks for your contribution. Here is the information on <strong>' . $_FILES['uploadedfile']['name'] . '</strong>!</p>';
					echo '<p>Name of Ad: ' . $_FILES['uploadedfile']['name'] . '</p>';
					echo '<p>File width and height: ' . $ad_size . '</p>';
					echo '<p>Company: ' . $company . '</p>';

						if($comments) {
							echo '<p>Comments: ' . $comments . '</p>';
						}

					echo '<h2><a href="upload.php?action=upload">Upload another file?</a></h2>';

				} else {
					echo '<h2>Upload failed!</h2>';
					echo $_FILES['uploadedfile']['error'];
				}

Thank you I will try that...now for displaying the uploads on the page allowing users to download the files...how would i go about doing that?

You would assemble your download link like this:

<a href="uploads/download.php?id=' . $id . '"><img src="uploads/image.jpg" border="0" /></a>

here is a script I use for my downloads, now the download.php file must be in the uploads directory

<?php

$base_dir = "PATH_TO_UPLOAD_DIR""; //The place you'll store the files

$id = $_GET['id'];

include "../includes/sql.php";

$query = mysql_query("SELECT column_name from table_name where upload_id = '$id'") or die("ERROR: " . mysql_error());

$row = mysql_fetch_array($query);

$file = $row['upload_name'];

$file_extension = strtolower(substr(strrchr($file,"."),1));

$filename = $base_dir . $file;

if ( ! file_exists( $file ) ) 
{
  echo "<html><title>eLouai's Download Script</title><body>ERROR: File not found. USE force-download.php?file=filepath</body></html>";
  exit;
}

switch( $file_extension )
{
  case "pdf": $ctype="application/pdf"; break;
  case "exe": $ctype="application/octet-stream"; break;
  case "zip": $ctype="application/zip"; break;
  case "doc": $ctype="application/msword"; break;
  case "xls": $ctype="application/vnd.ms-excel"; break;
  case "ppt": $ctype="application/vnd.ms-powerpoint"; break;
  case "gif": $ctype="image/gif"; break;
  case "png": $ctype="image/png"; break;
  case "jpeg":
  case "jpg": $ctype="image/jpg"; break;
  default: $ctype="application/force-download";
}
// required for IE, otherwise Content-disposition is ignored
if(ini_get('zlib.output_compression'))
  ini_set('zlib.output_compression', 'Off');
header("Pragma: public"); // required
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false); // required for certain browsers 
header("Content-Type: $ctype");
// change, added quotes to allow spaces in filenames, by Rajkumar Singh
header("Content-Disposition: attachment; filename=\"".basename($file)."\";" );
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".filesize($file));
readfile($file);
exit();

?>

Can anyone tell me what i need to change in my script so I can have these files save to an Upload folder on my first post script

Thanks

make sure you have enctype="multipart/form-data" in the form tag
