Why does my form keep calling itself?

woodsonoversoul · November 20, 2008

Hi all,

Firstly; I know that my code looks shabby. This is just a hobby project to see if I can create a multi-file upload script. The direction I'm trying to take is, initial information about a group of files -> a broken down list of each file with it's specific information(generated by the script, ie. new file names, etc.) and a place to select the file for upload -> the actual invisible upload script. My current problem is the second script/form doesn't access the upload script, but calls itself again with all the file information blank. Can you guys see why it's doing this?

Initial File: archiver.php

<html>
<head>
<title>Music Archiver</title>
</head>
<body>
<form name="archive_input" action="array_processing.php" method="post">

  <table>
    <tr><td><b>Enter Show Information:</b></td></tr>
    <tr>
      <td>Band:</td>
      <td><input type="text" name="band"></td>
    </tr>
    <tr>
      <td>Date:</td>
      <td><input type="text" name="date"></td>
    </tr>
    <tr>
      <td>Location:</td>
      <td><input type="text" name="loc"></td>
    </tr>
    <tr>
      <td>Set 1:</td>
      <td><textarea name="setOne" rows="4" cols="45"></textarea></td>
    </tr>
    <tr>
      <td>Set 2:</td>
      <td><textarea name="setTwo" rows="4" cols="45"></textarea></td>
    </tr>
    <tr>
      <td>Encore:</td>
      <td><input type="text" name="encore" size="39"></td>
    </tr>
    <tr><td></td>
      <td><input type="submit" value="Archive">
    </tr>
  </table>
</form>

echo "<input type=\"submit\" value=\"Everything looks satisfactory! Begin upload\" /></p>";
echo"</table>";
echo"</form>";
    
    ?>
    </body>
    </html>

and finally, the upload script: upload_script.php

<?php
//set variables
$x = 0;
$set_one = $_POST['set_one'];
$numOfFiles = count($set_one);

while($x<$numOfFiles)
{

echo "numOfFiles = " . numOfFiles;
echo $_FILES[upload_file][name][$x];
if(!empty($_FILES[upload_file])){   // this will check if any blank field is entered
$filename = $_FILES[upload_file][name][$x];    // filename stores the value

$filename=str_replace(" ","_",$filename);// Add _ inplace of blank space in file name, you can remove this line

$add = "/home/dan/MusicDataBase/$filename";   // upload directory path is set
//echo $_FILES[images][type][$key];     // uncomment this line if you want to display the file type
// echo "<br>";                             // Display a line break
copy($_FILES[upload_file][tmp_name][$x], $add);     //  upload the file to the server
//chmod("$add",0777);                 // set permission to the file.
unlink($_FILES[upload_file][tmp_name][$x]);
}
$x++;
}
?>

Now again, I know this is very poor code (it's a first attempt) but I still feel like it should at least try to open upload_script.php or throw an error. Any ideas?

Try removing this line from array_processing.php:

echo "<form>";

Forms can't nest, so that will probably take priority over any later form tags.

Awesome!! I commented that line out and it worked fine. Well, it didn't upload the file, but it did call upload_script.php. Thanks. Now to work out actually uploading files...
