[RESOLVED] Download Count - First script

EvansLight

Well im new to the world of php, been reading documentation and an ebook for about 2 days, so i wanted to test some of the stuff ive read, and actually doing is the best form of learning for me. So i made a simple download count script for my site. It should take the user to a pop-up and then after 5 seconds automatically download the file. The pop-up window also contains the code that should increase the download count of that file. Well its not working. Its not giving an error, but its not showing the download count on the page were you click the link to download the file.

If this doesnt make sense, well heres the coding. Its just the php, you can view the html directly at were i have the script at testing it:
http://phpstuff.stoneddevilinc.com/test.php

The php that is supposed to show the current amount of downloads:

<?php
// Opens the file that stores the downloads count
@ $file = fopen("count.txt","r+");
if (!$file)
{ 
  echo 'File Unavalible. Please Contact an Administrator.';
}

// Reads from the file the information, and Unserialize's it
@ $s_entry = file("count.txt");
if(!s_entry)
{ 
  echo 'File Unavalible. Please Contact an Administrator.';
}
$the_count = unserialize($s_entry);

//Echos the downloads count
if(!$the_count[0])
{
echo 'File has not been downloaded yet';
}
else
{
echo 'Downloaded: ' . $the_count[0] . ' times';
}

//Closes the file
fclose($file);

?>

This is the coding that is on download.php Its what is supposed to modify the download count then refresh the page to download the file:

<?php 

// Sets the diffrent files
$f_id= array('test.txt');

// Gets the ID of the download
$d_id = $_GET['d_id'];

// Opens the file that stores the downloads count
$file = @fopen("count.txt","r+");
if (!$file)
{ 
  echo 'File Unavalible. Please Contact an Administrator.';
}

// Reads from the file the information, and Unserialize's it
$s_entry = @file("count.txt");
if(!s_entry)
{ 
  echo 'File Unavalible. Please Contact an Administrator.';
}
$the_count = unserialize($s_entry);

// Increases the count for the downloads ID in the array
$the_count[$d_id] += 1;

//Seralizes the data for the count then writes it to the file
$f_entry = array(serialize($the_count));
fwrite($file,$f_entry);
fclose($file);

//Sets and gets the file for download
$url = $f_id[$d_id];
echo '<meta http-equiv="refresh" content="5;url='.$url.'">';
echo 'If Download Does Not Start, <a href='.$url.'>Click Here</a>';

?>

any and all help would rock. As i said, only been at this a few days, and cant figure out for the life of me whats going wrong 😕

It seems that your popup javascript function is missing ...

lol yea i kept forgettin to fix that. i always run javscript from seperate files, and i keep forgetting to add in the code in the head.

Fixed. Granted that shouldnt be stopping it from showing the count. I had the link set up to do it temp by just opening download.php in the page normally.

bogu

what is this line suppose to do?

$the_count = unserialize($s_entry);

is it correct?

lol i think it should be, i was told be another php developer to use serialize() and unserialize() as the functions to store the array containing the download count.

i was using the php.net documentation. Im just guessing that how i have it set up works right. I mean i get no errors, just the download count isnt increasing.

had 3 other php coders try, none can find whats wrong. Its normal for me a n00b to be stumped, but come on 😛

U shouldn't use something, because someone told u to use it, specially if u don't know how to use them, lets take a look unserialize() functions from php manual ...

mixed unserialize ( string str [, string callback] )

the first param of this function is a string, what is your param?

EvansLight wrote:
unserialize($s_entry); 

Did u ever look into your "count.txt" file to see how the content is stored, is it how u wanted to look?
And u should add this as your first line of code:

error_reporting (E_ALL);

because u should see a notice in this line:

fwrite($file,$f_entry);

looking into php manual:

int fwrite ( resource handle, string string [, int length] )

second param of this function is a string, what type of param do u have?
If your friends tells u what function u should use, I think they should explain u how to use them ...

I suggest u take a good look at your code, debug it, look into php manual to see everything how is working and what u are doing wrong, you still have a lot to work, if u have more question, don't hesitate to come here, search for them and if u cant find them create a new thread ...

GL and HF coding. 😃
