PHP - Question Regarding Client/server
I have a client and a server solution setup at the moment. We are currently creating an API that will be run on the clients end that will allow their clients to connect to them. On our end, we want to log the number of attempts are API is being used so that we may charge the clients appropriately.
My question is this. How is the most efficient way of doing this? Do I call mysql_connect from the client and just shoot the insert log statements across the web. Should I create a php script on our end that looks for post/get input and takes the data and inserts it? What if the client can't connect to our server; should I cache the data and send it off all at once? Should I create a job that every hour shoots up x records API requests happened? Relatively confused at what angle I should be taking when approaching this. I want this to be scalable to a point where we can have thousands of requests an hour, and not horribly slow down apache/mysql running at either end (Specially if the server is talking with several clients). Similar TutorialsI wish to create validation rules once which are used both on the client and on the server.
For instance, I will start off with the following PHP object:
stdClass Object
(
[rules] => stdClass Object
(
[email] => stdClass Object
(
[required] => 1
[email] => 1
[remote] => stdClass Object
(
[url] => check-email.php
[type] => post
[data] => stdClass Object
(
[username] => function() {return $( '#username' ).val();}
)
)
)
)
[messages] => stdClass Object
(
[email] => stdClass Object
(
[required] => an email is required
)
)
)
When the edit page is downloaded to the client, I will include this object in some format suitable to the client.
The client will then use the jQuery Validation plugin (http://jqueryvalidation.org/) along with the validation object, and client side validate the page.
When the form passes client side validation and is uploaded, PHP will use the same validation object to serverside validate the form (I have this part working as desired).
My question is how should I pass this data to the client? Originally, I would just use PHP to write some JavaScript.
exit('var myObj='.json_encode($myObj));
Note that when I json_encode the object, the value of $myObj->rules->email->remote->data->username is a string with quotes around it, however, I can easily use PHP to strip these tags before sending it to the client.
As Jacques1 pointed out in http://forums.phpfre...ascript-client/, I should never ever use PHP to generate JavaScript, and should use AJAX to download the JSON directly. I tried doing the later, but found that a callback function could not be included in the JSON.
Please advise on the best way to accomplish this.
Thank you
Hi, I need to make web site, which will get requests from users that log in and activate those scripts. But, the problem is that the server has to, when the script is activated, send request to another PC with the static IP address. Then, that PC should execute the script, send its results to server, and then the server will notice user who activated it (clicked on the link). So, the main problem is that server - client (static ip) communication, when the server is the first who sends request, not the client. Any instructions would be appreciated, thanks in advance. Hello; I know there is a way but I just can't get it out of my head. I have my code that i want to show to the user and then i have code i want to execute but not show anything to user. I no am not making my self clear which i am sorry for so ill give you an example. <? show_my_site(true); // Now i have code which will never output anything but the webbrowser will always wait for it to complete my_function_that_takes_time(true, 'Very Long'); ?> So what i want is some code to tell the browser thats it! You have everything. I cant use die; or exit; because i want to execute the code. Thank-you Paul I designed a web form that takes as input a file and that should upload that file on the server. The file is located on the client machine. The page containing the web form is handled by PHP script. I found out (reading 9483658954 forum topics so far) that there are 2 methods for getting a file uploaded. The first one is using FTP, and the second one using $_FILES variable. Unfortunately i have complains regarding both of the methods. Firstly, when attempting to upload the file using FTP it seems that rather the FTP server is calling "upload" a simple copy action (because the only successful thing i could do with FTP was to copy a file from location A to location B, both A and B being on the server) or I don't know to use FTP (which is probably the right answer). Then, when using $_FILES variable, I was forced to include ' enctype="multipart/form-data" ' in the form tag. After a long documentation I finally figured out that by including the enctype blah blah, the $_POST and $_FILES variables were NULL after the form was submitted.Still can't understand why! Are there any other methods for uploading a file from the client machine to the server? Can I get a competent script for this?
i have php at server side and c++ at client side.what i am trying to do is to constantly look for files on server in folder on server if there’s a file in folder then download it on client side and delete it from server folder Can someone please help me in setting up OAuth server and client implementation in PHP? Even after lots of googling I could only find very basic and raw examples which are very difficult to understand. Thanks in advance. Hi All - I'm trying to see if the below is possible using PHP. is it possible for php to allow a user to check if a port is open/listening on a remote server/PC, from their local machine. I've seen scripts on the web that talk about opening cmd.exe - this won't work as not all of my users will be on windows. Also saw fsock.. but the remote server is not serving http page(s). Also saw telnet, but again, some of my users may not have that windows feature enabled. Desired workflow: 1. user enters the server hostname/IP and a port 2. my php webapp will emulate checking if that hostname and port is open from the local user's computer.
thanks! This topic has been moved to Miscellaneous. http://www.phpfreaks.com/forums/index.php?topic=347977.0 I have a web portal which is scripted using client side scripting language i.e HTML. I want to create a login page in .php and want the other pages to be in .hmtl. Can i do so? I want to do this because i want the login password to be stored in a database. Also I want the password to get encrypted (by either MD5 javascript or OpenSSL ) when user enters it inside the login form. I cannot create the entire portal in php because my portal makes use of C code. And php doesn't have an interface with C language. Can a user get directed to a .html page after a secure login from login.php page ? My main aim is to secure the access to my web portal using a password. I tried to authenticate the login using javascript where the password was stored in an array. But i feel any one having moderate knowledge can easily break that password. Any help would be greatly appreciated!! I have to some how get data from my sql data to a clients sql db server. They suggested using xml which is great i can output the required fields as xml but how then do i push this so it goes into the clients sql db.. We cant just do a db insert this has been ruled out. Im happy using xml just have no idea how to push it at a particular host / sql db any ideas or suggestions would be really welcome.. Anyone know how I can print a file (specifically a PDF) that is stored on the server to the clients computer with a button? I don't want them to be able to view it, just print it. I've done some research and understand that there is no way to print directly without popping up the Windows Print dialog. And that is fine. I just want them to print this file, but not no where it is or be able to type in a URL to access it. Thanks Mike Hi.., I use below method to export data to excel. header('Content-type: application/ms-excel'); header('Content-Disposition: attachment; filename=abc.xls'); if I run the script from the server. (http://localhost/export.php) it is work. (pop-up window if i want save or open the file) but if i run the script from the client (http://192.168.1.5/export.php) it is not work. (nothing happen) any idea how to solve this? Nonsense question, but still... Is there any method to detect gmail client timezone setting? Like mobile app and web gmail client? Not browser or IP or similar, but gmail. Thank you for your answers. is it true that all the server side code runs before the client side code when accessing a webpage? if that is true, what about PHP code that is embedded inside HTML tags? wouldn't that result in an error a lot of times? I have been trying to learn how to build a php/mysql website using my local computer for testing. I'm at the point now where I need to move my files over to our server so I can give an update and show how much I have done. On my computer I have been setting up my include lines like this. include $_SERVER['DOCUMENT_ROOT'] . '/includes/head.inc.php'; the problem is that when I move my files over to the server I want to put them in a .htpassword protected directory called dbsite until the new site is ready to go live at which point I will move the files out of that directory and put them in the root dir. (there is currently I live site which I am replacing with this new one in the root right now, but until I'm ready I can't delete/overwrite the current one) My question is, is there a way to make $_SERVER['DOCUMENT_ROOT'] = the dbsite dir instead of the actual root dir? Just temporarily while the site is in the testing directory on the server. Otherwise I have to change all of my lines on my local computer from include $_SERVER['DOCUMENT_ROOT'] . '/includes/head.inc.php'; to include $_SERVER['DOCUMENT_ROOT'] . '/dbsite/includes/head.inc.php'; which will then cause the files on my local computer to not work correctly. Am I making sense as to my dilemma? Is there an easier/better solution? Thanks. Hi all. I have a video upload page utilizing ffmpeg to convert to .flv format via ajax with progress bar. Currently I am having an issue where the user uploads the video however the same upload script also converts to .flv format (exec("ffmpeg -i etc..")) after the file is uploaded. This is working fine however if the user selects to move away from the page after the video is uploaded it is causing the users browser to lockup (and sometimes crash). How can I make the exec() command to convert the video format strictly run server side and allow the user to move away from the page even though the conversion is still processing? Thanks for any advise on how to handle this issue. Before reading, just know I am NOT a PHP programmer and have no experience with PHP. I am just trying to install a premade php based website.
My questions is: How do I make .php pages connect to my database?
I know the question is very broad and probably doesn't really make sense but I've been having errors trying to install/configure a php website. The php website has a config which I have filled out correctly and seems to work on my PC via localhost using XAMPP fine but it doesn't work on my Windows Server 2012 Apache machine whenever the .php configuration tries to alter or conenct to the MySQL database it displays errors like this:
Fatal error: Call to undefined function mysql_connect() in C:\Apache24\htdocs\includes\classes.php on line 378
That's just an example of one predefined PHP website errors that I've received they are all very similar. What I think is happening is the PHP code is trying to connect to the database but there's some sort of configuration variable on Apache that I have not correctly filled out. I have tried this twice with two different CMS and searched google far and wide to find an answer to my problem. I hope the answer is something simple. If you need anything because you think you know what is happening then I will provide any information needed to fix this problem.
Thank you.
This may be a stupid question so forgive me if it sounds like a dumb question. I have my own server set up and I was wondering if it was at all possible to have a script running that is hosted on my server, while my PC is off or possibly just without having to load it within my web browser. I have a few scripts I wish to run forever without lagging my old PC. Is there a way to do this? Thanks. P.S All the scripts will be using the file_get_contents function to open HTTP streams, and a few explode functions here and there. I have a PHP web system that store in a windows server. In the system, there is a function for user to upload files to another server (Shared server in Unix). When i try to upload a file, it gives warning: Warning: move_uploaded_file(\\unixserver/sharedfolder/upload/test.txt) [function.move-uploaded-file]: failed to open stream: Permission denied in C:\wamp\www\upload\index.php on line 40 For your information, my username has been assigned in xxx's group that has access to read and write on that folder. Besides, i'm able to open,create and delete files on that folder's server manually (samba). The safe mode setting is off. Does anybody has any idea why this thing happen? I'm trying to make a simple website where people register to my website. When the user doesn't fill anything inside the boxes they get a message "Please fill all required fields" on the register.php page On my local host require_once works good. It shows up.
But when i upload the files to my sever the require_once does not show up on the register.php It just refreshes and i dont get the message "Please fill all required fields"
This is the code that works in local host but not in a live server <?php require_once 'messages.php'; ?>
Here is my full code
Register page: <html> <?php require_once 'messages.php'; ?> <br><br> <form action="register-clicked.php" method="POST"> Username:<br> <input type="text" name="usernamebox" placeholder="Enter Username Here"> <br><br> Email:<br> <input type="text" name="emailbox" placeholder="Enter email here"> <br><br> Password:<br> <input type="password" name="passwordbox" placeholder="Enter password here"> <br><br> Confirm Password:<br> <input type="password" name="passwordconfirmbox" placeholder="Re-enter password here"> <br><br> <input type="submit" name="submitbox" value="Press to submit"> <br><br> </form> </html>
Register clicked <?php
session_start();
$data = $_POST;
if( empty($data['usernamebox']) ||
empty($data['emailbox']) ||
empty($data['passwordbox']) ||
empty($data['passwordconfirmbox'])) {
$_SESSION['messages'][] = 'Please fill all required fields';
header('Location: register.php');
exit;
}
if ($data['passwordbox'] !== $data['passwordconfirmbox']) {
$_SESSION['messages'][] = 'Passwords do not match';
header('Location: register.php');
exit;
}
$dsn = 'mysql:dbname=mydatabase;host=localhost';
$dbUser='myuser';
$dbPassword= 'password';
try{
$connection = new PDO($dsn, $dbUser, $dbPassword);
} catch (PDOException $exception){
$_SESSION['messages'][] = 'Connection failed: ' . $exception->getMessage();
header('Location: register.php');
exit;
}
messages.php <?php
session_start();
if (empty($_SESSION['messages'])){
return;
}
$messages = $_SESSION['messages'];
unset($_SESSION['messages']);
?>
<ul>
<?php foreach ($messages as $message): ?>
<li><?php echo $message; ?></li>
<?php endforeach; ?>
</ul>
