PHP - Ajax Failing With 406

I've got an autodownloader for a file that I want my users to download when they click a link and the file is right but when a user downloads the file, the file is corrupted.

Code: [Select]
<?php
header('Content-Type: application/x-rar');
header('Content-Length: ' . strlen($data));
header('Content-Disposition: attachment; filename=Addypk.rar');
header('Content-type: application/octet-stream');
?>
It's not downloading the actual content of the file, rather, it's downloading the shell. Any ideas?

Can anyone explain this?

Warning: get_browser() [function.get-browser]: browscap ini directive not set in /home/albany/public_html/players_dir/dirupdate.php on .....

I'm trying to determine the browser so I can juggle my html a little bit.

Good evening!

Another bizzare thing that stopped working all of a sudden...

I have a registration form and this code no longer works...

// Check for First Name.
// Allow letters, space, period, apostrophe, and hyphen.
if (preg_match('/^[A-Z\'.-]{2-20}$/i', $_POST['first_name'])){
$fn = mysqli_real_escape_string($dbc, $_POST['first_name']);
} else {
// Add error-message to array.
$reg_errors['first_name'] = 'Please enter your first name!';
}


All day when I typed in a two letter answer - to speed up typing and testing - things worked fine, but now I get a built-in error message off to the side of the input box.

I typed 'ee' and that always worked before but no luck now.

The Reg Ex hasn't changed.

Could it be that there is a database connectivity issue that is screwing up my RegEx??

If I comment out all of the RegEx stuff then it works and my INSERT works - thanks to AlexWD

Hi

I.m trying to load an RSS feed from a google calendar. I'm using a script from the w3schools website which works with the demo RSS feeds. I changed the URL to my google calendar and for some reason it can't open the feed. I get an error:

Warning: DOMDocument::load() [domdocument.load]: I/O warning : failed to load external entity

I changed the calendar to a shared one and tried that URL but same result.

I found another script specifically for google calendar feed but same results.

The scripts open with other feeds but not google calendar.

ANy ideas?

Code: [Select]
<?php
//get the q parameter from URL
$q=$_GET["q"];

//find out which feed was selected
if($q=="Google")
  {
  $xml=("https://www.google.com/calendar/feeds/...group.calendar.google.com/private-313f84595f6e8dbfc7dc80f450d3e8be/basic");
  }
elseif($q=="MSNBC")
  {
  $xml=("http://rss.msnbc.msn.com/id/3032091/device/rss/rss.xml");
  }

$xmlDoc = new DOMDocument();
$xmlDoc->load($xml);
I removed the unique id for the calendar for now

Any help appreciated

My application just broke about 2 hours ago and for the life of me I don't know what I did to it?!     (I was coding a different file, and when I tried to run the main - unrelated index.php - things stopped working?!)

Here is a snippet of the suspect code...

if ($rows == 0){
// Email and Username are available.
// Add User to the database.
$q = "INSERT INTO users(username, email, pass, first_name, last_name, date_expires)
VALUES('$u', '$e', '" . get_password_hash($p)
. "', '$fn', '$ln', ADDDATE(NOW()), INTERVAL 1 MONTH))";
$r = mysqli_query($dbc, $q);


When I step through my code in NetBeans, the INSERT is failing and I don't know why because I haven't touched this code since this morning and it was working all day...

Please help!

i am using PHRETS ( http://dangodesign.n...h-rets-for-php/ ) to pull data off of a MLS RETS server.  i am successfully connecting to the server so the conditional is passing.  but my queries are pulling no results.  the provider tells me DMQL2 is the database. ive only ever worked with MySQL so im in the dark. 

if($connect) 
     {
           $sixmonths = date('Y-m-d\TH:i:s', time()-15778800); // get listings updated within last 6 months
           /* Search RETS server */
           $search = $rets->SearchQuery
           (
                'Property', // Resource
                //6, // Class
                'ResidentialProperty',
                '((Lud='.$sixmonths.'+),(Status=A))', // DMQL, with SystemNames

           );

OK, so I dont think this is a code issue as such, but I am completely stumped as to where the issue could be.

I have a page with some standard include() functions at the top. When I access the page from home, everything operates as it should, when I access it from work (on multiple machines), I get the standard "unable to open stream" and "unable to access" warnings for the include statements. I have tried hard refreshing and deleting cache (not that it should make a shred of difference) etc, but the error is still there after a week or so.

Does anyone know what could be causing this issue?

adding photo,Array ( [name] => profilepic.jpeg [type] => image/jpeg [tmp_name] => C:\xampp\tmp\phpB923.tmp [error] => 0 [size] => 152127 )

Hi,

We have been using this code for ages, but suddenly for some reason we cannot upload an image using the code below.

When we try to Print_r the $profilephoto variable, I get this error.

The filename is correct, but what is that [error]??  And how do I resolve it?

Oddly it does upload it locally, but LIVE, it won't 

This is the code.

if (isset($updatephoto))
{
echo "adding photo,";
print_r($profilephoto);
 define ("MAX_SIZE","5000");
 function getExtension($str) {
         $i = strrpos($str,".");
         if (!$i) { return ""; }
         $l = strlen($str) - $i;
         $ext = substr($str,$i+1,$l);
         return $ext;
 }

 $errors=0;

 if($_SERVER["REQUEST_METHOD"] == "POST")
 {
    $image =$_FILES["profilephoto"]["name"];
    $uploadedfile = $_FILES['profilephoto']['tmp_name'];

    if ($image) 
    {

        $filename = stripslashes($_FILES['profilephoto']['name']);
        $extension = getExtension($filename);
        $extension = strtolower($extension);


 if (($extension != "jpg") && ($extension != "jpeg") && ($extension != "png") && ($extension != "gif")) 
        {
            echo "Unknown Extension..!";
        }
        else
        {

 $size=filesize($_FILES['profilephoto']['tmp_name']);


if ($size > MAX_SIZE*1024)
{
    echo "File Size Excedeed..!!";
}


if($extension=="jpg" || $extension=="jpeg" )
{
$uploadedfile = $_FILES['profilephoto']['tmp_name'];
$src = imagecreatefromjpeg($uploadedfile);

}
else if($extension=="png")
{
$uploadedfile = $_FILES['profilephoto']['tmp_name'];
$src = imagecreatefrompng($uploadedfile);

}
else 
{
$src = imagecreatefromgif($uploadedfile);
echo $scr;
}

list($width,$height)=getimagesize($uploadedfile);
$newwidth=600;
$newheight=($height/$width)*$newwidth;
$tmp=imagecreatetruecolor($newwidth,$newheight);

imagecopyresampled($tmp,$src,0,0,0,0,$newwidth,$newheight,$width,$height);

i have a simple class which sees if there are any members in the database with the supplied details, then returns a simple number to show how many results there are, but it isnt working and throwing the error:

Code: [Select]
Warning: mysql_num_rows() expects parameter 1 to be resource, boolean given in C:\wamp\www\classTest\classes\user_process.php on line 52
here is the class:

and here is the call:

$user->login("username", "password");


All of the database details are correct and the values do match in the database. Where am i going wrong?

Note that this class is just for testing and not actually used.

Hello everyone:   I'm having trouble with code that compares a Form value ($uname) to Field values (username) from my database. In testing, I'm using the same Form data over and over, and I now have several identical records instead of just one unique record for this user.

  if (empty($_POST["uname"])) {
    $unameErr = "* Username is required";

  } else {
    $uname = test_input($_POST["uname"]);
    if (!preg_match("/^[a-zA-Z0-9]*$/",$uname)) {
      $unameErr = "* Only letters and numerals are allowed";

  } else {
      // Now sure the username is legit, we check to see if it's a
      // unique username by comparing it to all usernames already in member table.

      require_once 'login.php'; // This file contains database access credentials

      $db_conn = new mysqli($db_hostname, $db_username, $db_password, 'login');
      if($db_conn->connect_error) die ('Connect Error: ('.$db_conn->connect_errno.')'.$db_conn->connect_error);

      $query = "select username from member"; // Only selecting the field to compare to
      $result = $db_conn->query($query);
      if(!$result) die ('Database access failed: ('.$db_conn->connect_errno.')'.$db_conn->connect_error);	    

      $rows = $result->num_rows;
      for($i = 0; $i <= $rows; $i++) {
        if(mysqli_fetch_assoc($result) == $uname) { 
	$unameErr = "* Username already in use. Please choose another.";
	mysql_close($db_conn);
	exit;			
        }
     }
     $query = "insert into member values(NULL, '$uname', '$pwd1', '$fname', '$lname')";
     $result = $db_conn->query($query);
     if(!$result) die ("Database insertion failed: ".mysql_error());
    }
  }

This is my first attempt at this using PHP and am pleased that I can at least access my db. But I just can't figure out how to make this comparison check.   Thanks in advance for any help you offer.   ~Landslyde

I'm compiling and running C++ applications from PHP. I'm using backticks to capture the output of the applications ran. The output is just some simple text. In my case "Miles per gallon = x" where x is just a number. I cannot for the life of me get the comparison to return true. For example

Code: [Select]
$command1="./a.out1 <input1";
$a = `$command1`;

$command2="./a.out2 <input2";
$b = `$command2`;

if(strcmp($a,$b)==0){
...
}
else{
// this is always executing
...
} 
The two strings $a and $b are both "Miles per gallon = 10".

I have checked both variables using var_dump(bin2hex($a)) and get
dump1= string(42) "4d696c6573207065722067616c6c6f6e203d203130"
dump2= string(42) "4d696c6573207065722067616c6c6f6e203d203130"

Any idea on what's happening?

Now I'm having this strange issue with my website

I'm currently working on a tester system and I've encountered a problem that I'm unable to find the issue, tho I'm thinking my ajax php part of the script to be the thing causing it even tho it seems strange that it would cause it.

The first part which is connected to where the problem occurs is the echo"<form>"; and from there, It should take you to index.php?page=tester&select=answer, now that is where it in the browser goes there tho it still shows the page stuff from the last page which is index.php?page=tester&select=applications, so it's like showing both &select=answer and &select=applications on the same page.
<?php
$q=$_GET["q"];
include'../config/connection.php';
$result = mysql_query("SELECT * FROM applications WHERE id = '$q'");

echo "<center><table border='1'>
<tr>
<th>Account Name</th>
<th>Character Name</th>
<th>Gender</th>
<th>Skin Color</th>
</tr>";

$row = mysql_fetch_array($result);
  echo "<tr>";
  echo "<td>" . $row['name'] . "</td>";
  echo "<td>" . $row['charactername'] . "</td>";
  echo "<td>" . $row['gender'] . "</td>";
  echo "<td>" . $row['race'] . "</td>";
  echo "</tr></table></center>";
  echo"<br/>";
  echo"<table><tr>
  <th>Description</th>
<th>Metagaming</th>
<th>Powergaming</th></tr>";
echo"<tr>";
  echo "<td><textarea readonly='readonly' style='width:22em; height:20em;'>".$row['description']."</textarea></td>";
  echo "<td><textarea readonly='readonly' style='width:22em; height:20em;'>".$row['mg']."</textarea></td>";
  echo "<td><textarea readonly='readonly' style='width:22em; height:20em;'>".$row['pg']."</textarea></td>";
  echo"</tr></table><table><br/><center><h1>Answer</h1><br/><form action='index.php?page=tester&select=answer' method='post'>";
  echo"<textarea name='why' style='height:10em; width:60em;'></textarea><br/>";
  echo"<input type='submit' name='answer' value='Accept' /><a/>";
  echo"<input type='submit' name='answer' value='Decline' /></center>";
  echo"<input type='hidden' name='id' value='$q'/>";
  echo"</form></table>";
?>
Now on &select=answer it included a page which the script of that include consist of the stuff below, it outputs that the query was successfully, and all that.
<?
if(!empty($_POST['why']))
   {

   $why = mysql_real_escape_string($_POST['why']);

   $answer = trim($_POST['answer']);

   $id = $_POST['id'];

   if($answer == "Accept")

   {

   $query1 = mysql_query("UPDATE characters SET accepted = '1' WHERE id = '".$id."'");

   echo"Successfully accepted";

   $answer = 1; 

   }

   elseif($answer == "Decline")

   {

   echo"Successfully declined";

   $answer = 0;

   }

   $query = mysql_query("UPDATE applications SET answer = '$why' AND tester = '".$_COOKIE['Username']."' AND accepted = '$answer' AND answered = '1' WHERE cid = '".$id."'") or die('Could not connect: ' . mysql_error());

   if($query)

   {

   

echo"<br/>Query went through without problems";

  

header("Refresh: 5;url=index.php?page=tester");

   }
   }
?>
This is the ajax part javascript of it which gets the information for index.php?page=tester&select=applications
Code: [Select]
<script type="text/javascript">
function showApplication(str)
{
if (str==""||str==0)
{
  document.getElementById("txtHint").innerHTML="";
  return;
  }
if (window.XMLHttpRequest)
  {// code for IE7+, Firefox, Chrome, Opera, Safari
  xmlhttp=new XMLHttpRequest();
  }
xmlhttp.onreadystatechange=function()
  {
  if (xmlhttp.readyState==4 && xmlhttp.status==200)
    {
    document.getElementById("txtHint").innerHTML=xmlhttp.responseText;
    }
}
xmlhttp.open("GET","tester/applications.php?q="+str,true);
xmlhttp.send();
}
</script>If you need any more information feel free to ask for it.
Thanks in advance.

I've got a basic form for users on the site to fill out a form and upload a single image which is resized and saved to a directory on the server. I've tried the form numerous times and with images usually under 1MB the form successfully submits, data is queried and the image uploaded is resized and saved. However, recently I tried uploading larger sized images (1.2mb, 2.4mb, 3mb) and the script would seem to break. It wouldn't query any information, save any images, etc.

If you check my code attached, I have errors ready to output at all levels and not even any errors show up. When I hit submit after attempting to upload a larger file usually over 1MB, the page refreshes back to PHP_SELF as if it submitted but returns absolutely no message, alert or error and the form which was on the page is now gone.

I checked my PHP.ini file and my max file size upload is set at 32mb. Is there anything else with file size restrictions that I could be missing that is allowing this script to crash without even sending me any errors?

when i insert this code into my php script my cron job wont work

include($_SERVER['DOCUMENT_ROOT'] . DIRECTORY_SEPARATOR . 'facebook' . DIRECTORY_SEPARATOR . 'globalFunctions.php');

it is giving this error

Warning: include(/facebook/globalFunctions.php) [function.include]: failed to open stream: No such file or directory in /home/cork/public_html/facebook/fbFriendAdder/all/addFrndOfFrnd.php on line 13 Warning: include() [function.include]: Failed opening '/facebook/globalFunctions.php' for inclusion (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/cork/public_html/facebook/fbFriendAdder/all/addFrndOfFrnd.php on line 13

what is causing this problem and why does it work fine when i run the script manually??
