How do i create a image uploaing page?
I want the user to be able to select multiple pictures with just one window (ctlr click on pics, or drag for selected ones.)
And then upload them all to the server..

I could only find out how to get 1 picture working..

imageupload.php

CODE
<html>
<head>
<title>HTML Form for uploading image to server</title>
</head>
<body>
<form action="upload_file.php" method="post" enctype="multipart/form-data">
<p>Pictures:
<input type="file" name="file" />

<input type="submit" value="Send" />
</p>
</form>


</body>
</html>


upload_file.php
CODE
<?php


  /*
   foreach ($_FILES['file']['name'] as $i => $name) {
      
        if ($_FILES['file']['error'][$i] == 4) {
            continue;
        }
      
        if ($_FILES['file']['error'][$i] == 0) {
          
             if ($_FILES['file']['size'][$i] > 99439443) {
                $message[] = "$name exceeded file limit.";
                continue;  
             }
                $target_path = getenv("DOCUMENT_ROOT")."/Civic Association/upload/";
echo $target_path;
                $target_path = $target_path .basename( $name);

                if(move_uploaded_file($i, $target_path)) {
                    echo "The file ".  $name.
                    " has been uploaded";
                } else{
                    echo "<br><b>There was an error uploading the file, please try again!</b>";
                }
            echo "<br>";
             $uploaded++;
        }
  
   }
  
   echo $uploaded . ' files uploaded.';
  
   foreach ($message as $error) {
      echo $error;
   }
*/
/*foreach ($_FILES['file'] as $position => $file) {
    // should output array with indices name, type, tmp_name, error, size
    var_dump($file);
*/
    
    
if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/png")
|| ($_FILES["file"]["type"] == "image/pjpeg"))
&& ($_FILES["file"]["size"] < 200000000000000000000000000000))
  {
  if ($_FILES["file"]["error"] > 0)
    {
    echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
    }
  else
    {
    echo "Upload: " . $_FILES["file"]["name"] . "<br />";
    echo "Type: " . $_FILES["file"]["type"] . "<br />";
    echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
    echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />";

    if (file_exists("upload/" . $_FILES["file"]["name"]))
      {
      echo $_FILES["file"]["name"] . " already exists. ";
      }
    else
      {
      move_uploaded_file($_FILES["file"]["tmp_name"],
      "upload/" . $_FILES["file"]["name"]);
      echo "Stored in: " . "upload/" . $_FILES["file"]["name"];
      }
    }
  }
else
  {
  echo "Invalid file";
  }
?>

Note sure about HTML4. HTML5 apparently allows multiple files, but only together with the MULTIPLE attribute, and I have no idea about browser support.

QUOTE
ctlr click on pics, or drag for selected ones.

That might require that the files where in the same directory, which may not always be the case.

How about using several file INPUT elements instead?

I have tried the several inputs. But I have no clue how to get them to upload. I can get one using the code posted before. I just can't get anymore.

Do you use "[]" in the form field name(s), as explained here:
http://www.php.net/manual/en/faq.html.php#faq.html.arrays (and the following FAQ entry)?

Haven't done this for a long time, but this seems to work for me:

CODE
<?php
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past
?>
<!doctype html>
<title>multiple file upload test</title>
<?php
if(
isset($_FILES['file'])
&& $_FILES['file']['error']!=4 // error 4: no file was uploaded
&& $_FILES['file']['size']>0
)
{
    echo '<pre>';
    print_r($_FILES);
    echo '</pre>';
}
?>
<form action="" method="post" enctype="multipart/form-data">
<input type="file" name="file[]"><br>
<input type="file" name="file[]"><br>
<input type="submit" value="Upload">
</form>


The manual mentions multiple file uploads here: http://www.php.net/manual/en/features.file...ad.multiple.php
