PHP - Server Side Code: Uploads

I have a text box and a submit button. I want that when the submit button is pressed, the value on the text box will be checked if it matches the values that are on my server before proceeding, and if they don't match it should give an error report and stop.

All I can make myself is the text box and the submit button, I have tried for hours to find a way to do the rest, but all I can find on the internet are vague explanations and information that a novice like me cannot use. It would be a shame to let me web site that I have worked hard on to go to waste because I cannot do this myself 

Thank you in advance

I'm trying to learn how to validate a form using the php server side method. Everything I search is very different and old. Anyone have knowledge of a good tutorial or source that I could use? None of my books have anything about it either!

Thanks!

hello,

since php is run server side, can i launch a program (.exe) on the server from a link?

Hello,   I want to grab some data using a script from this site. But I am stuck right at the beginning. If you make a selection with the drop down boxes you get some output. For example you select: Selecteer competitienaam:  Najaarscompetitie 2014
Selecteer competitiegroep:  Eredivisie dames
Selecteer weergave: Programma (incl. uitslagen en stand)
Optioneel poule filter:  De Treffers R
Selecteer poule(s): Eredivisie - Poule A   I want to grab this output. When I look at the page source it is inside an iframe:

<iframe src="http://www.nttb-competitie.nl/" width="100%" height="1200" scrolling="yes" frameborder="0" name="NTTB_Competitie"></iframe>

I figured out: The script on the site first it gets url:

http://www.nttb-competitie.nl/selectie.php?anr=0

And after last selection it gets url:

http://www.nttb-competitie.nl/web_programma.php?reset=0&pidString=1009267&sc=0&vastgesteldeAfdelingsnr=0&cnid=10085&cid=10704&view=programma&pf=1269&pid=1009267

My problem is when I copy those URL's in a webbroser I get a page with only the words:

Ongeldige aanroep!

Which means "Invalid Call!"   So my question is: How can I grab the data instead of this stupid message. Is it even possible or is it somehow protected?   Please help!    

Basically what I am trying to achieve is making sure any $page called originates from my server, but if no $page is defined, to include a default page I have set up. This is my code, and I cannot figure out what's wrong with it.

Code: [Select]
<?php
  $path = 'pages/';
  $extension = '.txt';
 
  if ( preg_match("#^[a-z0-9_]+$#i",$page) ){
    $filename = $path.$page.$extension;
    include($filename);
  }
if (!$page)
include 'pages/main.txt';
?>
An example URL I am using is www.mywebsite.com/index.php?$page=pages/tester
What am I doing wrong?

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.   

Hey guys just thought I'd introduce myself as it's a polite thing to do. My name is Nick I am currently a front end developer and love learning new technologies so it looks like PHP is my next step.   I hope to learn and give whatever knowledge I can back

Hi I am presently writing a code which does the following steps given a site
1) get some keywords (written a function for it)
2) search google for these keywords (I have used curl and getURL functions for these)
3) perform keyword search in the first page of googles results.

Presently I have used curl and curl_multi_getcontent but when i run the code it consumes 100% of my server.
My server will not respond in this case if someone else pings.

I have been trying to do pcntl_fork, but could you let me know how to optimize this code by threading and forking.

I am a newbe in PHP please let me know the structure of how to invoke multiple threads and process the same.
If you have someother suggestions please let me know that too.

I have a javascript code that displays a monster hitting my character via client side only. It runs every 2 seconds via a setTimeout function.   My problem is... A user could just disable javascript all together, or craft their own code to disable the monster attack function.     I want to detect serverside if anything is being altered.  If that makes sense.     This is EXTREMELY hard for me to explain, I have no idea but my game is essentially turn based at this point. THE MONSTER ONLY DOES DMG if a player HITS IT. That way, I can safely, and change the values serverside with MYSQL.   What I want is the monster to attack the player every 2 seconds or so (Which I have javascript code for already), but a user could just manipulate that code and then attack the mob and receive only that damage. I want it to be more of an action attack game, where the monster's attack automatically, but securely... If that makes sense, any idea?   Would I have to implement some type of timing mechanism or something serverside? Or once the player spawned that mob..? Not sure. (You only have XX Seconds to kill!), but that doesn't really fix the problem..   TLDR: Autoattack mob system serverside.

Sorry if this is a silly question lol.

I want to know if there is an online tool I can use to check and see what PHP code will ouput server side.

For example:

<?php
$tomorrow  = mktime(0, 0, 0, date("m")  , date("d")+1, date("Y")); ?>

Hello I am using JSONP as dataType on my AJAX, but there's  an incident that a Transaction was successfully complete but a PHP error text occured while trying pass the data.   E.g.

SMTP Error: Data not accepted.
Unable to send Mail: SMTP Error: Data not accepted.<p>SMTP server error: Requested action aborted: This mail account has sent too many messages in a short amount of time. Please try later.
</p>

jQuery111001592713373247534_1407318091484({"result":11308,"err":"no"})

There was an unexpected error happen, SMTP Error. So in my javascript  jquery ajax the response will go to 

.error(function(xhr,status,error){
 console.log(xhr);
});

But the thing here is that the transaction  was successfully complete. So how do I tell the to the client side about the transaction process and the error happen? 

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!

Hi,
I have made a basic html site and it has two forms on it. I have the forms linking to a file called process.php.
Basically i need to know what code to put in the php file in order for the forms to save whatever is entered in them to a txt file on my server or computer.
Or any other easier way to do the same thing, save the content of two forms on my site.
Hope i posted this in the right forum subject.
Thanks very much for anyone that helps.

Hi All,

My goal is to process all redirects serverside and simply return the user to the 'final' URL.

Here's my function to get the final URL:
PHP Code:
function get_final_url($url){ 
    global $final_host; 
        $redirects = get_all_redirects($url); 
        if (count($redirects)>0){ 
          $final_url = array_pop($redirects); 
          if(substr($final_url,0,7) != 'http://' && !empty($final_host)) 
            { $final_url = 'http://'.$final_host.$final_url; } 
                return $final_url; 
        } else { 
                return $url; 
        } 

Here's the cURL execution:

$ch2 = curl_init();      
                        curl_setopt($ch2,CURLOPT_URL,$url); 
                        curl_setopt($ch2, CURLOPT_FOLLOWLOCATION, true); 
                        curl_setopt($ch2,CURLOPT_POST,''); 
                        curl_setopt($ch2,CURLOPT_POSTFIELDS,''); 
                        curl_exec($ch2); 
                        curl_close($ch2); 

For some reason, this works no problem, posts any data over to the URLs serverside, redirects serverside, and passes the client to the final URL, with none of the redirection displayed via HTTPWatch or any similar debug utility. Sometimes, however, it does show phases of redirection.

Any insight into what I might be doing incorrectly?

Thanks SO much in advance.
