PHP - Serverside Process Based Upon Url Request

Hey guys, I've hit a huge obstacle in my coding process of a script I am writing.

It is basically an uploading interface script and it works like this. I have files on my server and I want a user to click a button which fires a php script which in turn fires a bash script which IN TURN fires the uploading program (plowshare).

So to make it simple: user logs in, sees upload button. Clicks it, file starts uploading. I then want the user to see "upload initiated" and that's it. The problem is that with what I have now, the script just won't finish loading until the file has been uploaded and as a matter of fact I don't even think it is uploading anything :S

Here are the scripts:

PHP interface to call the bash script:
Code: [Select]
<?php

error_reporting(E_ALL);

function run_in_background($Command, $Priority = 0) {
if ($Priority)
$PID = shell_exec("nohup nice -n $Priority $Command 2> /dev/null & echo $!");
else
$PID = shell_exec("nohup $Command 2> /dev/null & echo $!");
return($PID);
}

function is_process_running($PID) {
exec("ps $PID", $ProcessState);
return(count($ProcessState) >= 2);
}

$file = $_GET['file'];
// Location of file relative to the index
$where = $_GET['where'];
// Absolute index location
$absolute = '/var/www/vhosts/animekyun.com/httpdocs/icarus/';
$where = $absolute . $where;
//$outfile ='log';
echo $where . $file . '<br>';

echo "<h2>The upload has been initiated!</h2>";

$ps = run_in_background("/bin/sh uploadparser.sh $file $where > $outfile");
while(is_process_running($ps))
//echo $output;
?>

Bash script to call uploading program:
Code: [Select]
#!/bin/sh
{
FILE=$1
WHERE=$2
FILENAME="/var/www/vhosts/animekyun.com/httpdocs/icarus/debug/debug_mu_$FILE"
FILENAME2="/var/www/vhosts/animekyun.com/httpdocs/icarus/debug/debug_multi_$FILE"
/usr/local/bin/plowup megaupload "$WHERE$FILE" >> "$FILENAME".txt 2>&1
/usr/local/bin/plowup multiupload "$WHERE$FILE" >> "$FILENAME2".txt 2>&1
} &

this works fine when I pass the variables as arguments in CLI

I hope i have been clear enough, it does seem rather confusing

I have been trying to figure out how this is done?  One php file and all that changes is the name of the brand and the logo.  This has to be clickable from a menu and also if a user changes the brand name it changes to the appropriate name and logo.  Any ideas as to how this is done?  If you can guide me in the right direction or give me an example of how this is done would be greatly appreciated.  Thanks.

i have a form for which the data is sent to a process page via jquery like so:

Code: [Select]
jQuery.post('<?php echo $this->site_root; ?>/modules/new_post_process.php',{
        message:jQuery("#message_contents").val() } ,function(data)
        {etc...

new_post_process checks the contents of message like so:


if (empty($message) && empty($error))
    {
        $is_error = true;
        $error = 'Please Enter A Message';
    }


the problem is that it always throws this message even when the textarea isnt empty. however after the error has appeared if i submit again it goes through fine. I suppressed the error and tried and the database gets populated with an empty value which means it is indeed empty. so why does it work on the second time around? I am using CKEditor for the textarea. everything else gets submitted normally but this textarea. heres the full code:


the textarea:

Code: [Select]
<textarea cols="80" rows="10" id="message_contents"></textarea> Code: [Select]
jQuery("#new_post_form").submit(function()
    {
jQuery.post('<?php echo $this->site_root; ?>/modules/new_post_process.php',{
        user_name:jQuery("#user_name").val(),
        redirect_url:jQuery("#redirect_url").val(),
        subject:jQuery("#subject_field").val(),
        forum_id:jQuery("#fid").val(),
        topic_id:jQuery("#tid").val(),
        method:jQuery("#method").val(),
        message:jQuery("#message_contents").val() } ,function(data)
        {
            if (data == 1)
                {
                    jQuery("#process_info").removeClass().addClass("subject_okay").html("<img src=\"<?php echo $this->template_path; ?>icons/small_tick.png\" alt=\"icon\" />Redirecting...").fadeIn("slow");
                    var URL = jQuery("#redirect_url").val();
                    document.location = URL;
                }
                else
                {
                    jQuery("#reply_btn").css("visibility", "visible");
                    jQuery("#draft_btn").css("visibility", "visible");
                    jQuery("#process_info").removeClass().addClass("subject_error").html('<img src="<?php echo $this->template_path; ?>icons/small_error.png" alt="icon" /> ' + data).fadeIn("slow");
                }
        });

and the process page:


if (isset($_POST['subject']))
{
$message = $_POST['message'];

if (empty($message) && empty($error))
    {
        $is_error = true;
        $error = 'Please Enter A Message';
    }
if (empty($error) && $is_error == false)
    {
        $query = $link->prepare("INSERT INTO 
                ".TBL_PREFIX."posts
                (p_fid, p_tid, p_poster, p_name,
                p_content, p_time_posted)
                VALUES
                ('$forum_id', '$topic_id', '$user_name',
                '$subject', '$message', '".$config['time_now']."')
                ") or die(print_link_error());

echo "1";
    }
    else
    {
        echo $error.'-'.$message;
    }

Hi guys,

I want my application to run a triggered process based on time to execute some tasks, what is the best approach?

Thanks

I have this code:
$shell = new COM('WScript.Shell');
$shell->Run("C:\WINDOWS\system32\cmd.exe /K ".$ini['indexer']['command'], 0, false);

When it runs, it opens the command line, but then when it is done, it leaves the process open. How can I close it when the process is complete?

I have a full working order form in PHP.  I process it and display it with a process page called "process.php."  Whenever this information is displayed on the web page "process.php" I also want it to send me an e-mail with all of the information that it just processed.  i.e. Checked checkboxes, text entered, etc. Whenever I try to send the contents of "process.php" to an email $message = include 'process.php';  the process page just goes through an infinite loop displaying itself over and over again instead of sending itself in an email.

hi there,

I have a chained combo boxes. I manage to get the values for the sub process using onchange event.My problem here is how can I retain the values in the sub process combo box after the page is loaded?

Hi

Im doing a login for a website I've built and Im having troubles,

The connection to the actual database works fine, no errors,  but when trying to verify data in the database to log on and get to a secure area i just get the incorrect username or password that i created for when details are incorrect.

heres the code where the problem lies

Any help would be appreciated

<?php
session_start();
require("db_connect.php");

$username = $_POST['uname'];  
$password = $_POST['pword'];

$sql = "SELECT * 
FROM login_details 
WHERE username='$username' 
AND password='$password'";
$results = mysql_query($sql, $connect);
$numofrows = mysql_num_rows($results);
if ($numofrows == 1) {
$_SESSION['username'] = $row['username'];
$_SESSION['loggedin'] = true;
header ("Location: secure_page.php");
die();
} else { 
$_SESSION['error']= "Icorrect Username Or Password"; 
header("Location: login.php");
die();
}

?>

this retrieves data from a webservice at Library of Congress
for example this here
http://www.loc.gov/standards/sru/simple.html

What I want to do is process the XML? into a string of usable text to put in a mysql database
Am I getting XML back or what?
save it and run it to see. In firefox, it shows xml headers, in chrome just the text elements.

Hi all,

Newb here with a few months of PHP experience.

I'm working on a project where if a web user signs up for a 30-day trial, they need to be notified near the end of that trial--let's say 25 days--that the trial is expiring. So I need some kind of batch process that runs in the background, perhaps every night at 1am, that looks at the signup date for all trial users and compares that date to the current date. If the difference is 5 days, then that user should be sent an email.

Does anyone know how to set up a nightly batch process that like this? I'm not concerned so much with the date comparison as I am with getting a daily process to run in the background. Coldfusion has something called a Scheduled Task, but being new to PHP, I don't know what would be comparable.

Any help welcome!

Thanks...

With the following code

<?php
extract($_POST);
include("database.php");
$sql=mysqli_query($conn,"SELECT * FROM register where Email='$email'");
if(mysqli_num_rows($sql)>0)
{
    echo "Email Id Already Exists"; 
    exit;
}
else(isset($_POST['save']))
{
    $file = rand(1000,100000)."-".$_FILES['file']['name'];
    $file_loc = $_FILES['file']['tmp_name'];
    $folder="upload/";
    $new_file_name = strtolower($file);
    $final_file=str_replace(' ','-',$new_file_name);
    if(move_uploaded_file($file_loc,$folder.$final_file))
    {
        $query="INSERT INTO register(First_Name, Last_Name, Email, Password, File ) VALUES ('$first_name', '$last_name', '$email', 'md5($pass)', '$final_file')";
        $sql=mysqli_query($conn,$query)or die("Could Not Perform the Query");
        header ("Location: login.php?status=success");
    }
    else 
    {
        echo "Error.Please try again";
    }
}

?>

There is still an error output of syntax error on line 11, please help, what's wrong with my code

I could use some suggestion on how to model the Checkout Process for my e-commerce site.

As I see it, when a person "checks out" there are 5 steps...

1.) Create an Account/Log-In
2.) Enter Addresses
3.) Choose Shipping Options
4.) Enter Payment Details
5.) Review & Place Order

I'm trying to avoid having gigantic "God classes" and struggling to figure out how to abstract things in good OOP terms.

My Head First: Design Patterns book talked about the "State Pattern" and I'm wondering if that might be a good approach?   

Maybe each of the 5 steps above could be a "state" in the Checkout Process?

What do you think?

I have this 3 tables users (id_user) music_styles (id_style, style) ex. (1) - (Blues) user_styles (id_user, id_style) I'm trying to create a form in which the user ($user = $_SESSION['id_user']) chooses through a multiple select the styles of preference to store them in the database using mysqli statements. If the styles prefered are selected they should be displayed in the select input later, how can i accomplish this? Thanks.
