[RESOLVED] Should this script work??

Lee_W

Should this script display whatever is selected in the drop down box once the submit button has been pressed: -

<form`action="" method="post" name="download_pricelist" id="download_pricelist">

    <select name="pricelist" id="pricelist">

      <option value="Pricelista">PricelistA</option>
      <option value="Pricelistb">PricelistB</option>

    </select>

    <input type="submit" value="submit" />

</form>

<?php
if (isset($_POST['pricelist']))
{
echo ($_POST['pricelist']);
}
?>

</body>
</html>[/B]

When I click the submit button nothing happens.

It will work after you replace the back-tick between <form and action= with a space. 😉

php_dev

The action of the form should be set to the page you are on. That way the form knows to post to itself.

Hope it helps,

Thanks for the reply guys.

However, I have now amended the code to this: -

<form action="downloadtest.php" method="post" name="download_pricelist" id="download_pricelist" enctype="multipart/form-data">

    <select name="pricelist" id="pricelist">

      <option value="">Lola</option>
      <option value="">Lee</option>

    </select>

    <input type="submit" value="submit" />

</form>

<?php
if (isset($_POST['pricelist']))
{
echo ($_POST['pricelist']);
}
?>

</body>
</html>[/B]

When I click submit it's looking for a page that doesn't exist as I get the 'HTTP 404 not found' error message.

if you click on the submit button, its action is to send all the variables into downloadtest.php ...

So put the form and php code into downloadtest.php ...

Lee_W

This is all in the same script which looks like: -

<form action="downloadtest.php" method="post" name="download_pricelist" id="download_pricelist" enctype="multipart/form-data">

    <select name="pricelist" id="pricelist">

      <option value="">Lola</option>
      <option value="">Lee</option>

    </select>

    <input type="submit" value="submit" />

</form>

<?php
if (isset($_POST['pricelist']))
{
echo ($_POST['pricelist']);
}
?>

</body>
</html>[/B]

The php script is on the same page as the form.

djjjozsi

you forget to add a value in your options...

if i open a file called: downloadtest.php and put this code, it shows what is set as value.
(please use the [ php ] [ /php ] around your php code.)


<form action="downloadtest.php" method="post" name="download_pricelist" id="download_pricelist" enctype="multipart/form-data">

<select name="pricelist" id="pricelist">

<option value="VALUE1">Lola</option>
<option value="VALUE2">Lee</option>

</select>

<input type="submit" value="submit" />

</form>

<?php
if (isset($_POST['pricelist']))
{
echo ($_POST['pricelist']);
}
?>

</body>
</html>

Thank you very much for helping me with this.

I have learnt more on this forum than I have reading the 2 books I have on PHP.

Your help is appreciated.

Now, I know how to action the selection from a dropdown list I want to take this to the next level if you can help me.

I have designed a dropdown list which automatically populates itself when you upload a file.

I now want to download whichever file is selected using the submit button.

Thanks.

djjjozsi

i have an easy way to make files selected from a bounch of checkboxes,

it make a zip file, and collect the selected files into one zip file,
and then makes an url to download it.

watch this method here:

hello,

This is the script I have written which is saved as an include file: -

<?php

if (isset($POST['pricelist']))
{
$getfile = $POST['pricelist'];

// define error handling
$nogo = 'Sorry, download unavailable.';

if (!$getfile)
{
// go no further if filename not set
echo $nogo;
}
else
{
// define the pathname to the file
$filepath = 'C:/htdocs/panasonic_system_pricing/'.$getfile;
// check that it exists and is readable
if (file_exists($filepath) && is_readable($filepath))
{
// get the file's size and send the appropriate headers
$size = filesize($filepath);
header('Content-Type: application/octet-stream');
header('Content-Length: '.$size);
header('Content-Disposition: attachment; filename='.$getfile);
header('Content-Transfer-Encoding: binary');
// open the file in binary read-only mode
// suppress error messages if the file can't be opened
$file = @ fopen($filepath, 'rb');
if ($file)
{
// stream the file and exit the script when complete
fpassthru($file);
exit;
}
else
{
echo $nogo;
}
}
else
{
echo $nogo;
}
}
}
?>

I want this script to open the file which is selected in the dropdown box once the submit button has been selected.

In the next post I will post the form page.

Lee_W

This is the actual main script: -

<?php include('includes/title.inc.php'); ?>

<?php include('includes/panasonic_system_pricelist_upload.inc.php'); ?>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN"
"http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">
<head>
<title>Trust Distribution Intranet<?php echo "—($title)"; ?></title>
<link rel="stylesheet" type="text/css" href="trust intranet.css" />
</head>

<body>
	<?php include('includes/header.inc.php'); ?>

	<?php include('includes/menu.inc.php'); ?>

	<?php
	//if the form has been submitted, display result
	if (isset($result))
  {
  echo "<p>$result</p>";
  }
?>

<form action="" method="post" enctype="multipart/form-data" name="upload_pricelist" id="upload_pricelist">

  <p>
    <label for="panasonic_system_pricelist">Upload pricelist:</label>
    <input type="hidden" name="MAX_FILE_SIZE" value="<?php echo MAX_FILE_SIZE; ?>" />
    <input type="file" name="panasonic_system_pricelist" id="panasonic_system_pricelist" />
  </p>

  <p>
    <input type="submit" name="upload" id="upload" value="upload" />
  </p>

</form>

<form action="" method="post" name="download_pricelist" id="download_pricelist">

  <p>
    <label for="panasonic_system_pricelist">download pricelist:</label>
    <select name="pricelist" id="pricelist">
      <option value="">Select a pricelist</option>

<?php 
include('includes/dropdown_menu.inc.php');
pricelist('c:/htdocs/panasonic_system_pricing');
?>

    </select>

  </p>

  <p>
    <input type="submit" name="download" id="download" value="download" />
  </p>

</form>

<?php
include('includes/panasonic_system_pricelist_download.inc.php');
?>

	<?php include('includes/footer.inc.php'); 
	?>

</body>
</html>[/B]

When I run the script I get the following error messages: -

Warning: Cannot modify header information - headers already sent by (output started at C:\htdocs\Panasonic_system_pricing.php:3) in C:\htdocs\includes\Panasonic_system_pricelist_download.inc.php on line 20

I have found the solution to this error message.

I have put <?php ob_start(); ?>

at the start of the main script & <?php ob_flush(); ?>

at the end of the main script.

However, when I select a file & click submit it opens a window asking me if I want to save or open but I get an error when trying to open a PDF file as it says:

Acrobat could not open 'tda15_spec_sheet[1].pdf' becuase it is either not a supported file type or because the file has been corrupted(for example, it was sent as an email attachment and wasn't correctly decoded).

Any idea's?

Lee_W

Any suggestions on this would be appreciated.
