Storing Data from a php form back to another php form already opened.

I have a form created using PHP and HTML. Within the form is a link to another form in PHP that opens and allows a file to be downloaded. See code for the MAIN FORM(This is opened first by user):

************************************************************************
<table width="99%" align="center" cellpadding="0" cellspacing="7" bgcolor=#ccccff style="border: solid #333399 1px; color: 000000;">

                          <tr align="center" valign="middle">
            <td colspan=4 nowrap><a href="attachment2.html" target="_blank"><img src="IMAGES/paperclip.jpg" alt="Download File" border="0"></a>
              Download Attachment &amp; Enter File Name below
              <input type="text" name="attachment"></td></tr>
                  </table>
************************************************************************

When they click the paperclip it opens attachment2.html file. This code allows the user to browse and download a file. See code below(This opens second):



************************************************************************
<form enctype="multipart/form-data" action="upload.php" method="post">
    <input type="hidden" name="MAX_FILE_SIZE" value="100000000" />
    Choose a file to upload: <input name="userfile" type="file" />
    <input type="submit" value="Upload File" />
      <input type="reset" value="Reset" />
</form>
************************************************************************


This then runs another php file (upload.php) and uploads the file. See code(code just runs, message is displayed and user can click close button):


************************************************************************
<?php
$uploadDir = 'uploads/';
$uploadFile = $uploadDir . $_FILES['userfile']['name'];
echo "<pre>";
if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadFile))
{
    echo "<h3>File is valid, and was successfully uploaded.</h3> ";
}
else
{
   
    echo "<h3>Upload conflict! File was not uploaded!</h3>" ;
}
echo '
<form>
<center><input type="button" value="Close" onClick="javascript:top.close()"></center>
</form>';
echo "</pre>";
?>

***********************************************************************
HERE IS THE QUESTION: How do I get it to pull the name of the file that is chosen in the ATTACHMENT2. html (userfile field) and enter it automatically in the MAIN FORM (attachment field)?

$_FILES['userfile']['name'] only gives you the file name... php does this so that you can add, for example, "uploads/" in front of it like in your example above.

if you do an "echo $_FILES['userfile']['name']" you will get just the filename printed to the screen....


<script>
window.opener.document.request.attachment.value = "<?php echo $_FILES['userfile']['name']; ?>";
</script>

If I understand you correctly, you wish to change a text-input value on a parent window from a child window.

The easiest way is to use "opener"
for info on "opener" see http://www.webreference.com/js/tutorial1/opener.html

on the form place an 'onSubmit' which uses opener to assign the value of the file input to the text input OR do the same thing from the page that uploads the file.

I wish to take the name of the file that is being defined (downloaded) in the userfile textbox from the attachment2.html file and send it back to the MAIN form and have it fill in and store in the attachment field within the MAIN FORM so that the user will not have to manually enter the name of the file he/she has downloaded. When the user actually submits the main form, the name of the file that was downloaded will then be added to the field in the MYSQL database via PHP.

an example:

first page:

<form name="myform" > 
  <input type="text" name="attachment">
  <a href="test2.php" target="_blank">test2</a>
</form>

click on test2 and ....
second page:
<head>
<script>

      function doit() {
            alert(document.myform2.myfile.value);
            window.opener.document.myform.attachment.value = document.myform2.myfile.value;
      }
</script>
</head>

<body>
<form name="myform2" onSubmit="doit();">
      <input name="myfile" type="file">
      <input type="submit">
</form>
</body>


Then the user picks a file, when they click submit, the filename goes into the original page's textbox

additionally:

you may want to only add it to the field after the upload is completed, in which case just move the code into the if statement assuring that the upload was successful.

Ok I got this working using alpha characters(see example "p" in code) in regards to storing a name of a file into a textbox on the previous page, but I can't get it to work when I am trying to use the \ character as in an example file name m:\test\allphy.jpg. I want to store just the file name, not the directory locations. Have tried various thing with no success. Your thoughts????


function carryvar(){
var name = document.attach.userfile.value;
var c = name.lastIndexOf("p");
var finalname = name.substring(c);
alert(finalname);

window.opener.document.request.attachment.value = finalname;





}

You could use regular expressions to separate the last name from the string OR

what I probably would do is store $_FILES['userfile']['name']  instead of the form field value.

window.opener.document.request.attachment.value = $FILES['userfile']['name']
(since the page that the uploader form submits to is in the same window - 'opener' should function the same)

This way you can also make sure that the file itself was uploaded successfully before transferring it over to the form.

Let me know if that does it.

I have already done this, but I want to manipulate the file name to just give me the actual file name and not the directory for information purposes. The directory will vary from user to user and I don't really care about that. I can code to eliminate this process on an unsuccessful download, but I need to recognize the last "\" to determine the actual file name....
