PHP - Temporary Download Files

Hi, how much bandwidth is used for 1000 downloads per day or for each download? Is it safe to have no download limits? Thanks

I have a Joomla website having one folder for audio files in it and their links are saved in database.

Now I want to show two calendars to the user at front end, so that they can choose that from when to from he want to download the audio files?

for e.g he can select june-2-2014 in one calendar and august-2-2014 in second calendar, now on clicking download button the files residing between the two specific dates must get archived into one zip file and then start downloading...
  i have a reference link for creating a zip and downloading the zip :http://coursesweb.ne...-archive-php_cs   now i am stuck that how to get the selection of user from calendar , save it into the array , and from the array get the files from the folder matching the array indexes and then zip , download them.   please tell me how to achieve this task ?

My users table on my forum is what gets checked everytime a user refreshes to authentic them.    When killing a monster, I want users to be able to grab items and it will insert them into their inventory. I have this part done already. But I want them to have a plethora of loot available that drops from a mob, and once they click the specific item it will then be inserted into their inventory (server database).   I'm storing the Temporary Item Data in a PHP session variable. Once they kill a monster, the Tempory Item Data variable get's filled with the specific loot and then the user will have the option to choose what items they want to go into their inventory.   My problem is, if they open the game in a new browser they will get a new session id. Since I'm authenticating them through my users table, can I just make a new column called session_id and just use php's session_id() before every session start so no matter which browser they're on they will have the same session right?    You might think, well why dont you just store the temporary item data in a mysql field or rows instead? I want to try to minimize mysql usage as much as possible, as players will be CLICKING a lot to kill mobs, it is most likely very mysql demanding as well and I want to be intuitive about it. I just want to use temporary session data for the loot. Then once the user clicks an item they want, it is EXTRACTED from their tempory item data variable, then I will use MYSQL to insert those items into their inventory.    Is this a fair and intuitive way to do temporary data for item loot? For example, in action RPG's like Path of Exile you kill a group of mobs and you see a shit ton of loot on the floor. (I imagine that loot is just temporary waiting for someone to pick it up right?) Once you do pick it up, mysql is then called to save it right? That's the same logic I have with my web based game. Is using a session variable to store that temporay loot.   Is this an intuitive way to do this, or are there other ways?

I'm using a popular PHP script for my web site, which uses main_1.htm for the header and footer, and inner_index.htm for the main part of the home page. Also, of course it has index.php.

How can I set up a duplicates of these files to work on and test changes to the home page, before I actually deploy the changes on to my live site's home page?

Thanks

After the file gets uploaded, I intend the file to become renamed, and then moved to its destination folder.

Though to move the file, I need the newly renamed file name and also its location, which is the temporary folder, and the latter describes my question.

This is the script as follows:
Code: [Select]


$avatar_tmp = $_FILES['avatar_upload']['tmp_name'];



                                // Rename the file into a more usable file name
                                $new_file_name = $user_name . '_' . rand(111111, 999999) . '.jpg';   
                               
                                rename($avatar_tmp, $new_file_name);     
                                   
       
                           
                                                                                         
                                // Move the uploaded file on the disk to its folder
                                 
                                // The directory of the temporary folder is needed in front of the new_file_name variable
                                                             
move_uploaded_file ($new_file_name, $target);

The directory of the temporary folder is needed in front of the new_file_name variable and my question is, is there any function, to get the directory of the temporary folder for the uploaded file? So I can insert it in front of the new_file_name variable and move it out of the folder to its destination folder?

Can anyone tell me, how the temporary file names (name of the file which is created in the 'tmp' dir  ) generated by PHP when the files are uploaded ?

Are there any algorithms used ?

Basically I would like to place a link on my website and have the user download a file, but rather than just right clicking and choosing save target as, the link must be clicked, on the next page the file is fetched and then the client can download the file. How would I go about setting this up please?

When the download appears the link that is produced doesn't show the actual download either, so users can't leech of it.

Thanks

I have this interesting problem, I think I know how to do it.   In a java class I took there was a lab on swapping the values of variables and if there were two variables, you needed a third temporary value holder.   So this project I'm working on has a row output, currently the individual values are outputted as a concatenated string but ideally they would be independent rows with accompanying buttons.   One of those buttons is a ^ symbol, when you press this, ideally the row is moved up in ID putting the previous ID in front or ahead.   The problem is that the ID's / rows are not necessarily in sequential order.   So, when I recall a set of rows that have random sequential values for example, 2, 5, 27, 41, 43   and those are outputted by themselves, now becoming 0,1,2,3,4 respectively or 1,2,3,4,5   So when I try to move 43 to position 2, that's 4 positions away or 4 clicks of the ^ button.   Now how do you deal with that 4 difference and the difference of 41... ? thereby, when the initial set of rows are recalled again, the order is now, 43, 5, 27, 41, 2 Of course the ID I think remains the same but the data is switched... ? yeah I have to draw some pictures, but this isn't a current problem to fix, later on down the road after I update the interface.   here is a drawing to explain, I'm more of a visual person    wp_20150112_05_27_16_pro.jpg   59.67KB   0 downloads   Any ideas would be appreciated, otherwise I will post my solution when I come to it. Or I don't figure it out and find one. thanks

Ok here is what i got so far and now I am stuck.  The user enters a number of how many squares (rectangles is note accurate) they wish to calculate.  If its between 1 and 100 it continues, if its any other number it tells you to put in a number between 1 and 100.  That was easy for me to do.

If the number is between 1 and 100 it creates and input for length, width and height of each rectangle. creating the variables as it goes, i.e. "length$i" when $i is the while counter and increases to the ammount of rectangles you wished to view.  Again, not that hard for me.

 So I am at the point where is I put in 50 I get length1 - through length30, width1 - width50, and height1 - height50.  THis works great.  However I now what to store those variables and calculate the area of each one via a while look which again creates an area$i variable which can be added (it would create area1 - area50 which I then wish to add together)

Here is what I have so far.

<?php

    if ($_REQUEST['numpack'] <= 0 || $_REQUEST['numpack'] > 100 ) {

Now I was reading up on session data and think this might be the best way to go, but again how do I do this? and two I want to make sure that if there are 2 people accessing it at the same time, it does not change the variables on them... (i.e. user one puts in 50 values, and user two puts in 50 different values I do not want cross contamination)

Any ideas on how to proceed?

Hello folks, well what I mean by temporary variables are variables like error messages or success messages that appear after a form has been submitted.  I want to be able to kill these variables when the page is refreshed and return the page to its defualt state.  For example, I'm making this simple page which is basically a form that ask users for some information, then upon submit, stores the  in a database and prints a success message.  If the form is filled out incorrectly or some form fields are left blank, then error messages are printed. What I really want is for these messages to disappear when the page is refreshed.  My current model uses a second page to handle the form, and then upon succes or upon encountering an error, redirects to the form page, passing the error or success variables via the url to the form page where they are printed out.  What can I do differently to achieve what I want (ie kill variables upon page refresh)? Below are the form page, and the page that handles the form respectively.

Also, another problem I just noticed is that, the errors[3] variable isn't getting passed back to the form page.  I don't know if it's because the url can only pass so much info to a second page. The page in question can be located he

Bear with me, as I'm still quite new at PHP.

I'm trying to figure out the best way to build a search function for a database that will eventually be quite large.

The path of the search I'm building is to go from a straight-forward javascript and html search page, to a paginated search result. Then the user can narrow down those query results based on a new search of their results.

In trying to get the pagination to work across several pages(unsuccessfuly, I might add), I've been learning about sessions and temporary tables. But, because the database will be very large, I'm wondering if they are the wrong way. Sessions have a time limit, and temporary tables delete once the connection is closed.

Is it possible/feasible to build a permanent table that puts in the search variables, with a unique id and use this to manage the searches, pagination and all that? Then, at some point in the process, I can put code to delete the corresponding row (or even make it a saveable search). Maybe somebody sees where I'm going with this and  can describe it better than me? I'm just thinking off the cuff at the moment. Maybe there's some terminology that will help me find a tutorial. Any bit helps.
thanks!

I have made a Php program that downloads an Inno setup installation file for installing a program. However, if I for one or another reason want to make a new download of the same Inno setup installation file, the previous file will still be found in the Download folder. Each of the downloads get a number in parenthesis, setup(1), setup(2), setup(3) etc. However, I wondered if it is posible to erase the previous file in the same process as I download a new one, so that however many downloads I do, there will all the time only be one occurence of this file in the Download folder.

The download code is as follows:

$exe = "Inno script/Test_setup.exe";
	header("Content-Type: application/octet-stream"); 
	header("Content-Disposition: attachment; filename=\"Test_setup.exe\""); 
	header("Content-Length: " . filesize($exe)); 
	readfile($exe); 

Thanks in advance.

Sincerely

 

Hello


I have a simple question about file handling...


Is it possible to list all files in directories / subdirectories, and then read ALL files in those dirs,
and put the content of their file into an array?

Like this:

array:
[SomePath/test.php] = "All In this php file is being read by a new smart function!";
[SomePath/Weird/hello.txt = "Hello world. This is me and im just trying to get some help!";

and so on, until no further files exists in that rootdir.

All my attempts went totally crazy and none of them works... therefore i need to ask you for help.


Do you have any ideas how to do this?
If so, how can I be able to do it?


Thanks in Advance, pros

So far I have managed to create an upload process which uploads a picture, updates the database on file location and then tries to upload the db a 2nd time to update the Thumbnails file location (i tried updating the thumbnails location in one go and for some reason this causes failure)

But the main problem is that it doesn't upload some files

Here is my upload.php

<?php
include 'dbconnect.php';

$statusMsg = '';

$Title = $conn -> real_escape_string($_POST['Title']) ; 
$BodyText = $conn -> real_escape_string($_POST['ThreadBody']) ; 
	 

// File upload path
$targetDir = "upload/";
$fileName = basename($_FILES["file"]["name"]);
$targetFilePath = $targetDir . $fileName;
$fileType = pathinfo($targetFilePath,PATHINFO_EXTENSION);
$Thumbnail = "upload/Thumbnails/'$fileName'";

if(isset($_POST["submit"]) && !empty($_FILES["file"]["name"])){
    // Allow certain file formats
    $allowTypes = array('jpg','png','jpeg','gif','pdf', "webm", "mp4");
    if(in_array($fileType, $allowTypes)){

        // Upload file to server
        if(move_uploaded_file($_FILES["file"]["tmp_name"], $targetFilePath)){

            // Insert image file name into database
            $insert = $conn->query("INSERT into Threads (Title, ThreadBody, filename) VALUES ('$Title', '$BodyText', '$fileName')");
            if($insert){
               $statusMsg = "The file ".$fileName. " has been uploaded successfully."; 

		$targetFilePathArg = escapeshellarg($targetFilePath);
		$output=null;
		$retval=null;
		 //exec("convert $targetFilePathArg -resize 300x200 ./upload/Thumbnails/'$fileName'", $output, $retval);
		 exec("convert $targetFilePathArg -resize 200x200 $Thumbnail", $output, $retval);
		echo "REturned with status $retval and output:\n" ; 
		if ($retval == null) { 
		echo "Retval is null\n" ;
		echo "Thumbnail equals $Thumbnail\n" ; 
		}

            }else{
                $statusMsg = "File upload failed, please try again.";
            } 
        }else{
            $statusMsg = "Sorry, there was an error uploading your file.";
        }
    }else{
        $statusMsg = 'Sorry, only JPG, JPEG, PNG, GIF, mp4, webm & PDF files are allowed to upload.';
    }
}else{
    $statusMsg = 'Please select a file to upload.';
}

//Update SQL db by setting the thumbnail column to equal $Thumbnail
$update = $conn->query("update Threads set thumbnail = '$Thumbnail' where filename = '$fileName'");
            if($update){
               $statusMsg = "Updated the thumbnail to sql correctly.";
		echo $statusMsg ;  } 
else 
{ echo "\n Failed to update Thumbnail. Thumbnail equals $Thumbnail" ; } 


// Display status message
echo $statusMsg;
?>

And this does work on most files however it is not working on a 9.9mb png file  which is named "test.png" I tested on another 3.3 mb gif file and that failed too?

For some reason it returns the following

Updated the thumbnail to sql correctly.Updated the thumbnail to sql correctly.

Whereas on the files it works on it returns

REturned with status 0 and output: Retval is null Thumbnail equals upload/Thumbnails/'rainbow-trh-stache.gif' Failed to update Thumbnail. Thumbnail equals upload/Thumbnails/'rainbow-trh-stache.gif'The file rainbow-trh-stache.gif has been uploaded successfully.

Any idea on why this is?
