send to php function the number of the link clicked

Jac

Hi!

Could you help me something I cannot solve?

On a php page there are several link with downloadable
source code (*.zip). For example:
<a href="../source1.zip">source1.zip</a>
<a href="../source2.zip">source2.zip</a>

How could I send the number of the link to a php function that places this number into a mySQL database. I know the database handling, but clicking on a link how to send this number to php function? It would be graet if no further page apperared.

Please write me sort examples to understand!

(For example:

on page download.php:

<?php
function save($number)
{
...
//database handling gose here
...
}
?>
<body>
...
<a href="../source1.zip">source1.zip</a>
...
</body>

Thanks for your reply!

download.php would be another script to the one that has the form.

<a href="download.php?source=1">source1.zip</a>
<a href="download.php?source=2">source2.zip</a>

download.php would then look at the value of $_GET['source'] and, after making sure that it's there and valid, sets a bunch of [man]header[/man]s to say that the following response is a zip file with a certain name (Content-Type: application/zip, for example), and then follow those with the zip file itself ([man]fpassthru[/man] would be a reasonable choice for this).

Hi,

if you want to use the same script to update the counter you have to insert the filename into your database. After this its easy read the filename and use the rec. id to update the record of the downloaded file.

Of course you can use some file functions like Weedpacket suggested, but it is some new functionality.

Hi!

I found a code that seems to be ok, but when downloads the file, it displays the content not the usual Windows download form.

Would you look at the code?

<?php
$src=1;
echo $src;
switch ($src) {
case 1: $fname = "php1.xls"; break;
case 2: $fname = "php2.xls"; break;
}

header("Content-type: application/xls");
header("Content-Disposition: attachment; filename=$fname");
$fp = fopen($fname, 'rb');
fpassthru($fp);
?>
