Update a counter when a link is clicked

[Ian Davies]

Hello

I have seen some tutorials to put a update a counter field in a record. I
have the counter field in a table that also has a field for a path to file.

I display the records in a table on a web page e.g.

IndexNo ............Tit le............. ............... .... Link
............... ............... ...... Count
......1........ .....MyFileName ........www.mysite/files/MyFileName.doc........
......0
etc

User can click on the Link field in the table to download the file.

The problem is I can't find a way that will run an update query along the
lines of

$Query = mysql_query("UP DATE Resources SET Count = Count + 1 WHERE IndexNo
= '$IndexNo');

when the user clicks the link

Can anyone suggest a way or direct me to a tutorial

Thanks
Ian

Hi,

Your question is very clear, but if I understand right, this may help:

1) Make a link to a increasecounter .php and add the filename:
<a href="increasec ounter.php?file name=MyFileName .doc">

2) In increasecounter .php:
$filename = $_GET["filename"];
// do your update in the db here

3) Redirect to the file
header("Locatio n: MyFileName.doc" );
exit;

Thanks for your advice
Your code was just what I was looking for
It is updating the table with the counter but it is not bringing up the file
to download any more

The modified code is as follows

<a href="increasec ounter.php?file name=<?php echo $Link; ?>"

The $Link returns the full path to the file (from the same table as the
count field)

In my increase counter.php I have

*************** *************** *********
$filename = $_GET["filename"];
echo $filename;
$Query = mysql_query("UP DATE Resources SET count = count + 1 WHERE Link =
'$filename'");
header("Locatio n: $filename");
exit;
*************** *************** *********
I put the echo in just to check the file name is correct
which it is as it is used in the SQLs WHERE clause and it updates the record
as I mentioned earlier
But the file to download is not appearing. Can you see what is wrong
The address in the browser window is as follows if it helps
http://www.mysite.co.uk/increasecoun...ers/MyFile.doc

which appears to be wrong
when the file was downloading previously the address would have been

http://www.mysite.co.uk/Resources/Others/MyFile.doc

Any clues
Thanks
Ian

You cannot have anything printed before header(). Remove echo filename;
and try running the script.

Hope this helps.

Thanks and God Bless!!
