PHP - Run Command After Process Initialization
hello,
I have this problem in running a specific command after using shell_exec or exec to execute a certain process. The process I am running is unimrcpclient, after initialization, it expects some command to be entered in order to communicate with the mrcp server. however, passing the command as an attribute is not an option. Is there a way in PHP to execute a process, wait for initialization and then pass the command automatically? thank you. Similar TutorialsHello! I am executing an external command from a PHP script, using the exec function. Since this program can take more than 1-2 minutes to run, I thought I should use a "Loading page...please wait". What I need is to be able to get the process id from the external program that is being run and, when this finishes, I'll start outputting the results. Is there a way to do this? The SOAP request initialization is taking too long to execute. We have analyzed the system and application logs which suggest that the issue resides with SOAP request initialization. We are using PHP5.3 to call .net web service using SOAP. Please suggest. 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; } 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 hi, is there a way to tell php to do a process again? example: Code: [Select] $draft_number=rand(1, 15); if($draft_number == 5){ START OVER AT TOP } else { $sql1 = "UPDATE names SET draft = '$draft_number' WHERE id = '$uid'"; $result1 = mysql_query($sql1) or die('Error, Check you fields and try again.'); } This may spill over into java, just not quite sure yet! Basically what I am trying to do, is fill a box with text, click a button which runs a function which send the text in the box via a JSON request to an external server. The JSON works fine, I just want a way of submitting the string which hopefully doesnt involve a form, but its the only way I can think of! Any other ideas? 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.
Edited by AP_King7, 20 August 2014 - 10:51 AM. 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.

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?

I have here a script that allows a GSM/ Remote receipt printer to poll for data in a specific format. The issue is that I will be deploying a few 100 of these damn things and need to know what ones are on or off! I can get the time I polls the file and have it writing to a DB table. The only issue is that even with only two printers running its filling up the table fast! Over 600 rows in 30 mins for only two printers! I need to find out a better way to do this but have the same flexibility in knowing what exact times it was on and off and then to take this data and put into a nice viewable format! This should be safe with a few hundred printers at once. Hope someone can help me with this as I am totally stumped! =/ Hi all,
I am building a website for my local motorclub.
we are wanting to start taking online payments for membership and events. I have built a members only area - the way to get access is for a member of staff to accept the registration. this is all fine for members who pay via cheque or simular.
I am wanting a sign up process to include the payment page, was going to use paypal as the merchant. So if people want to join the club they are able to do so and get immediate access to the members only page instead of waiting for staff to check if the payment has cleared then set up there account etc.
so basically i need a sign-up form (which is done) then a purchase button at the bottom, which takes the payment and then redirects to the website but 'tells my website the payment has been taken and to give full access'.
I cant really explain how i want it, but i hope you understand from what i have said.
With the following code
<?php ?> There is still an error output of syntax error on line 11, please help, what's wrong with my code 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.
