PHP - Moved: Need Tutorial On Comet (reverse Ajax) For Polling Client From Server

I 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 am calling the sms service provider server with the following code


$url = $urlAccount_home."?username=".$userAccount."&password=".$passAccount."&number=".$number."&sender=".$userSenderSMS."&msg=".$msg;


             if (!($fp =fopen($url,"r")))
echo "<br><center>خطا في الاتصال </center><br>";

$result =fread($fp,10);
fclose($fp);








When sending sms to 1 person no problem, but when sending sms to more than 1 person example for a group,

i will poll the serve in loop...

what am afraid is calling the server more than once continuously, wont affect the service?

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).

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.

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?
