PHP - How To Block A Video From Being Accessed Via Url?

how to block someone from visiting my page using ip adress ?
this is the case
if someone come to my site then we record the ip address and put it into database.
when the visitor come again with the same IP they cannot see my page (block them) and redirect it to somewhere page.

How is it that a site can forward to my site without a trace?

www.2mysite.com is forwarding traffic to www.mysite.com but

$page_name = $_SERVER['HTTP_REFERER'];
echo $page_name;

does not show www.2mysite.com as the referring site...how does one hide this?

Help?

I draw contents from a database. Some of the texts contain a footnote, which is formatted using a div class. Following the HTML of this:

<div class=""footnotes"">
<br>
<hr align=""left"" noshade=""noshade"" size=""1"" width=""150"" />
      <blockquote> <a href=""#f1"" name=""fn1""> <span class=""superscript""> * </span>

        </a>Some footnotetext</blockquote></div>

Since my bibliography uses data from the database as well, the footnote now appears before the references, but I would like it at the very bottom of the page. I was thinking of using preg_replace in order to separate the textfield into two variables, one for the text itself, the other one for the footnote (it is always just one) and integrate after the bibliography is compiled.    Unfortunately, it seems that the preg_replace does not work. It always displays the whole content of the textfield. Here's the PHP:

$text = preg_replace('/(.*)(\div class=\"footnotes\"\>.*?\<\/div\>)/s', '$1', $result['text']);$footnote = preg_replace('/(.*)(\div class=\"footnotes\"\>.+?\<\/div\>)/s', '$2', $result['text']);

echo '<div align="justify"><span style="font-family:Georgia;font-size:16px;">' . $text;

...

echo $footnote; 

Maybe someone has an idea how to deal with that. I tried it on phpliveregex. There search string works fine. Many thanks for any help.

It's one of those days after a long weekend and a rainy morning.

Simply trying to get the correct message depending on the variable's value

if($a = 'one'){
echo "POOR";}
if($a = 'two'){
echo "GOOD";}
if($a = 'three'){
echo "VERY GOOD";}
if($a = 'four'){
echo "EXCELLENT";}

Not sure if I need to use ==, extra quotes, or ELSEIF for the best result.

 

I'm trying to clean up some past coding for a project of mine and this block keeps standing out like a sore thumb, but it works and i can understand it.

What it's doing is comparing each of the users submitted data to the admin-set data and then flagging if there any errors or not.

Any suggestions on a different approach?

Code: [Select]
foreach ($_SESSION['usersData'] as $k => $v) {
foreach ($this->info as $m => $n) {
if ($m == $k) {
if ( ($n['required'] && ( empty($v) || !isset($v) ) ) ) {
$_SESSION['errors'][$k] = TRUE;
} elseif ( (!$this->escape_data($v,$n['type'])) && ($n['required']) ){
$_SESSION['errors'][$k] = true;
} elseif ($n['required'] && ($v == $n['default'])) {
if ($n['readonly'] != true)
$_SESSION['errors'][$k] = true;
} elseif ($n['required'] && $n['readonly'] && ($v != $n['default']) ) {
# Box is required, set to readonly and has a default value, if this triggers then the user has tampered with our form.
$_SESSION['usersData'][$k] = $n['default'];
} elseif (isset($_SESSION['errors'][$k])) {
unset($_SESSION['errors'][$k]);# = false;
}
} elseif ( isset($this->info['file']) ) {
if ($this->info['file']['required'] && $_FILES['file']['size'] == 0) {
$_SESSION['errors']['file'] = TRUE;
} else {
unset($_SESSION['errors']['file']);
}
}
}
}

Say I have a server written in PHP (don't ask ). Let's say I have 10 users connected to my script and one of those users, for the sake of the example, needs 10MB of data sent to them. If I send that data via socket_write(), does my program execution stop (therefor locking up every other user) until the data has gone through, or is the actual task of sending data over the tubes passed on to some lower level OS function so my program can get on with its flow?

Hi,
I want that user can only read my article but can't download it. neither with save page as or with view source, even not with selecting text. and copy and paste. is there any solution in php to do that.
Please help
Thanks

So I'm debating whats the best method. I'm aware that catch/blocks should be used in exceptional cases but what if it saves me from having 4 nested if/else conditions? The following is code for an xbox registration site
Code: [Select]
try {
    // check code is valid
    $c1 = $this->input->post('code1',true);
    $c2 = $this->input->post('code2',true);
    $c3 = $this->input->post('code3',true);
    $gt = $this->input->post('gamertag',true);
    $pass = $this->input->post('password',true);
    if(
    $c1 == '' || $c2 == '' || $c3 == '') {
        throw new FormError("Authorization code invalid.");
    }
    // check db for code validation
    $q = $this->db->query("select * from `codes` where `activated` = 0 and `code` = ".$c1.$c2.$c3." limit 0,1");
    if($q->num_rows() != 1) {
        throw new FormError("Authorization code invalid.");
    }
    $r = $q->row_array();
    $email = $r["recipient_email"];
    $codeGt = $r["gamertag"];
    // check valid gamertag
    $q = $this->db->query("select * from `users` where `gamertag` = '".$gt."'");
    if($q->num_rows() > 0) {
        throw new FormError("Gamertag already exists.");
    }
    // validate gamertag /w inputted gamertag
    if(strtolower($codeGt) != strtolower($gt)) {
        throw new FormError("Gamertag Invalid");
    }
    $this->_createAccount($email,$pass,$gt);
    // show register-thanks screen
    $this->load->view("register-thanks",$data);
    $success = true;
} catch (Exception $e) {
    $data['error'] = $e->getMessage();
}

Hey   Need help i am having a mental block   when I fill in the form and click send it sends the form but looks like this

Name: , 
Email: , 
Subject: , 
Message:

<?php
$name = $_POST['name'];
$email = $_POST['email'];
$subject = $_POST['subject'];

$formContent = "From: $name, \n Email: $email, \n Subject: $subject, \n Message: $message";
$recipient = "email@email.com";
$subject = "Website Request";
$mailheader = "Website \r\n";
mail($recipient, $subject, $formContent, $mailheader);
echo "Your message was sent" . " - " . "<a href='index.html' style='text-decoration: none; color: #d03837;'>Return Home</a>";
?>

Anyone with any ideas

Guys/Gals;

This below block outputs a very simple progress bar, i'm curious if anyone would see a solution to perform a task when this bar reaches the end as you can see it's set to countinue until width<400 when that 400 is true I and in essence the process is done (even though nothing in reality) i want to display countinue but only when it's done

echo "<table width='100%' border='1' cellpadding='1' cellspacing='1' bgcolor='#666666'><tr><td width='506' height='52' valign='top'><script type='text/javascript'>function progress(){if(document.images['bar'].width<400){document.images['bar'].width+=5;document.images['bar'].height=5; 
   }else{clearInterval(ID);}}var ID;window.onload=function(){ID=setInterval('progress();',$cpuspeed);}</script><img src='images/white.gif' name='bar'/><br /><font color='#ffffff'>Cracking....</font></td></tr></table>";

any dideas

In PHP?

Let's say I'm going off of:
width x height





So this is 2x1

2x1

2 blocks across, 1 block height.

How do I check this against other blocks in php to see if the 2x1 will overlap another set of dimensions dynamically?

Am I over thinking this?

I have the code below working perfectly, but I was wondering if there is a more eloquent way to write this, specifically handling the exceptions...

This creates an object of a Router Class that parses my clean URLs into a Controller name, method name and the rest are arguments.

So for example: www.domain.com/users/view/profile/bobsmith would route to the Users Controller, and find the viewUsers
method and pass the arguments "profile" and "bobsmith" to it, and the method would take it from there... works great.

That explains what this code does. My only question is if there is a cleaner way to handle the exceptions, so I don't have
"throw new exception" written four times. Thoughts? Or is it good to go?



$rawURL = getPageURL();
$router = new Router($rawURL,$rootDIR);
$controller = $router->getController();
$method = $router->getMethod();
$arguments = $router->getArguments();

try {
// check controller exists and set controller path //
if ((isset($controller) && ($controller != ''))) {
$controllerPath = APPLICATION_PATH . "controllers/" . $controller . ".class.php";

// check controller path exists //
if (file_exists($controllerPath)) {
    
// set method name and check method exists //
if ((isset($method) && ($method != ''))) {
$methodName = $method . ucfirst($controller);

if (method_exists($controller, $methodName)) {
// test it out //
$test = new $controller();
$response = $test->$methodName($arguments[0]);
echo $response;
}
else {
// method_exists failed //
throw new Exception("That method does not exist foo!");
}
}
else {
// method was not found in URL //
throw new Exception("No method name was given foo!");
}
}
else {
// file_exists failed //
throw new Exception("That controller does not exist foo!");
}
}
else {
// controller was not found in URL //
throw new Exception("No controller name was given foo!");
}
}
catch (Exception $e) {
// spit it out foo //
echo $e->getMessage();
}

Hey Guys,
 
Hope you are all having a great day

I was hoping somebody could help me with preventing my blog from being attacked by SQL Injection. I made a simple blog in using PHP and MySQL but I keep getting spam comments (even though I use re-captcha) and some files were overwritten on my web server. For all my input I use mysql_real_escape_string but I still get the problem.

I found a video on youtube that showed how to enter stuff on the address bar like "order by 2--" and "union all select...." after passing a variable etc, and all of the things in the video could be replicated on my site   I am guessing that is my problem, but the video did not tell me how to resolve the issue and I am sick of having to delete hundreds of spam comments per day and check my web server for uploaded files.
 
How can I stop people adding these commands to the address bar and getting data from my database?  I really need your help
 
Thanx,
 
Jen

Hi the

I have a PDF form that generates an XFDF file (form field valies in XML form) and I am passing it to PHP for processing. I am having trouble pulling a specific value from the XML block because of the way that the XML data is generated and organized. Please see a sample of the XML block below:

'test.xml' file:
Code: [Select]
<?xml version="1.0" encoding="UTF-8"?>
<xfdf xmlns="http://ns.adobe.com/xfdf/" xml:space="preserve">
<annots/><fields>

<field name="Non">
<value>Off</value>
</field>

<field name="PayRequest">
<value>XYZ</value>
</field>


From the above XML snip it, once it's sent to PHP, I would like to somehow reference the "PayRequest" field value and retrieve the value "XYZ" and assign it to a variable. I have been kicking around some code that I thought should work, but doesn't appear to. If anyone could offer any insight to get it working that would be greatly appreciated.

PHP Code:
Code: [Select]
$prq_ret = simplexml_load_file('test.xml');
foreach($prq_ret->xpath("//field[@name='PayRequest']") as $item) {
 
 $row = simplexml_load_string($item->asXML());
 //print $item->value;
 print $row;
 }
