PHP - Php Compare Post Script Not Working?

Can I post my "Add a Comment" script here to get help improving it?

Users make entries into a form on my site which are then sent to a remote server which generates a variable length page of results for the users perusal.  I want the results to be displayed on my site but I discover that iframe height is a problem so I am trying PHP in a separate file to avoid an iframe.  Then maybe I can cache the result pages and display them without any height difficulties and not having to fiddle with javascript.

The first PHP code I try is prevented from working and I discover that the apparent cause is the issue of fopen and fsockopen etc. being set to off by the host that I use because of security concerns:

$url="http://remote_server.cgi";
foreach($_POST as $key => $value)
{$url .="$key=" . urlencode($value) . "&";}
$array = file($url);]

The host has cURL so I try that but the form entries are not being accepted as they are with a direct post from the form:

$URL="http://remote_server.cgi";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $URL); 
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $_POST);
curl_exec ($ch);    
curl_close ($ch);

In case useragent is a problem at the remote server, I added:

curl_setopt($ch,CURLOPT_USERAGENT,'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.13) Gecko/20080311 Firefox/2.0.0.13');

I know all entries are received by the separate file by using:

print_r($_POST);

But the remote server still says "Error in form found. You are not authorized etc. etc... "

Apparently the post data is not being sent like the form sends it.

Any suggestions?

Ive tried everything and cannot get this POST to work, page comes up blank. The output of curlgetinfo() shows:

As the title says session, post and get are not working. This is what i use to initialize them. For get just switch session with get.

Code: [Select]
foreach ($row as $val)
          { 
            $_SESSION[$rowcount] = $val;
//              echo "<td>$val</td>\n";
                $rowcount=$rowcount+1;
      }
when i was using session i would check to make sure that they were working with a couple of these lines in the same php document.

Code: [Select]
echo "Session row 1 = ".$_SESSION[0]."<br />";
echo "Session row 2 = ".$_SESSION[1]."<br />";
then on the next page where I was trying to receive the variables i was using this just to start off with and make sure i was getting the variables.

Code: [Select]
session_start();
if(!isset($_SESSION[1])){
echo "help1";}else{$var=$_SESSION[1];
}
echo $_SESSION[1];
echo $var;
if i switch to post and get i get the same results. if there is an easier way to pass variables between pages id love to hear them

I have a page, that upon post, does some logic, this logic can take 1-30 minutes...
Now sometimes I will get a "Page time out"....and others i wont... even if im requesting the same data.

I used it successfully everytime on my stock xp, with ie8
But cant get it to work on my VISTA WIN7 x64 machins, and another xp machine, after about 1-5 min it says "page time out", then i test it on my stock xp machine, and it can run for 45 min, or runs until everything is finsihed and shows the page.

Any ideas?

Is there a quick an easy way to test my php scripts without creating an html form and specifying values that I post to my php script? Maybe a firefox plugin or some tool that can be used to do it quicker?

In the long haul, quicker, not just one time

Hi all,
Since twitter changed the way they allow people to post, my simple php script to grab the $_POST data from an input and post it to my twitter profile has broken.

I've been reading up on Oauth, but none of the documentation is clear at all. It's quite complex, in fact - they assume you are creating a full app, which I am not - I just want to flick some text to twitter.

I just want to pass a simple string variable to my account - can anyone help me with how to do this?

All help appreciated.

Hi,

I'm trying to get HTTP post to work on my server but even the most basic script does not work. Can anyone help me?

PHP script:

<?php
echo 'Hello ' . htmlspecialchars($_POST["name"]) . '!';
?>



I try and POST data to the script using:
http://www.czoryk.co.uk/post_test.php?name=Chris

But when I try and do that only ' Hello ! ' is displayed. I'm sure this is just a simple error but I can't figure out what's wrong.

Thanks, Chris

I am working on a website where I have comments posted by users. I want to display 25 comments and if there are more, it will show a linke Older Posts similar to Facebook. Once I click on that, it will list down the next 25 comments and so on. This is something we can see in Facebook. Do you have any idea where I can find this script. I did search on google but couldn't find it. Probably bad keyword selection.

any ideas for the resource.

Thanks,

Faisal

I have a problem about Blog Post Categorization  Script. Can anyone review it ? Instead of showing how much posts that category have it just repeats.

Code: [Select]
<?
$sqlCategories = "SELECT * FROM blog_entry, categories where blog_entry.CategoryID=categories.CategoryID and blog_entry.UserID=".$_REQUEST['UserID']." order by Category asc";
$resultCategories = mysql_query($sqlCategories, $conn);
if (@mysql_num_rows($resultCategories)!=0){
$strcategory="";
while($row_categories = @mysql_fetch_array($resultCategories))
{
$categoryduplicate=0;
$arrcat = explode(",",$strcategory);
for($i=0;$i<strlen($arrcat);$i++)
{
if($arrcat[$i]==$row_categories['CategoryID'])
{
$categoryduplicate=1;
}
}
if($categoryduplicate==0)
{
if($strcategory=="")
{
$strcategory=$row_categories['CategoryID'];
}
else
{
$strcategory=$strcategory.",".$row_categories['CategoryID'];
}
$sqlCategories2 = "SELECT * FROM blog_entry where CategoryID=".$row_categories['CategoryID']." and UserID=".$_REQUEST['UserID'];
$resultCategories2 = mysql_query($sqlCategories2, $conn);
if($row_categories['CategoryID'] == $_REQUEST['CategoryID'])
{
echo "

}
else

Hey guys!
I have a site in flash that talks to a PHP file...
the flash site has some forms and those variables are sent to php.

I am having some trouble with this security code I implemented on php:


// Host name from where the form is authorized 
// to be posted from:  
$authHosts = array("mysite.com"); 

// Where have we been posted from? 
$fromArray = parse_url(strtolower($_SERVER['HTTP_REFERER'])); 

// Test to see if the $fromArray used www to get here. 
$wwwUsed = strpos($fromArray['host'], "www."); 

// Make sure the form was posted from an approved host name. 
if(!in_array(($wwwUsed === false ? $fromArray['host'] : substr(stristr($fromArray['host'], '.'), 1)), $authHosts)){     
   //logBadRequest(); 
   header("HTTP/1.0 403 Forbidden"); 
       exit;     
} 


On IE and Google Chrome the site works fine! but on FireFox Flash pops up an error message telling me that the php file has a sequence error.

Any ideas or suggestions on how to fix this?

Thanks in advance!
Cheers.

I've managed to isolate a problem I'm having with my php script. It would seem the script randomly restarts itself with blank post data while it's running.

I've managed to mimick the problem using a very basic php script which just pauses and writes to a log:

<?php

$q = $_POST['q'];

if ($q==""){
  writelog ("MISFIRE!!!");
  die;
}

writelog("\n*** Error check started ***");

for ($i = 1; $i <= 50; $i++) {
   writelog ($i);
     sleep(rand(2,20));
}

 function writelog($towrite)
{
  $tdate=date('d/m/Y H:i:s');
  $file = 'log/testlog.txt';
  $current = $towrite." --- ".$tdate."\n";
  file_put_contents($file, $current, FILE_APPEND);
}

writelog("*** Error check ended ***");
?>

To rule out any problems with my AJAX htmlhttp requests, I simply send the script some irrelevant post data using Chrome's Advanced Restful client.

This is the ouput of the log from an example test run:

*** Error check started *** --- 05/06/2014 18:27:30

1 --- 05/06/2014 18:27:30
2 --- 05/06/2014 18:27:44
3 --- 05/06/2014 18:27:49
4 --- 05/06/2014 18:27:59
5 --- 05/06/2014 18:28:04
6 --- 05/06/2014 18:28:22
7 --- 05/06/2014 18:28:33
8 --- 05/06/2014 18:28:39
9 --- 05/06/2014 18:28:52
10 --- 05/06/2014 18:29:08
11 --- 05/06/2014 18:29:22
12 --- 05/06/2014 18:29:30
13 --- 05/06/2014 18:29:43
MISFIRE!!! --- 05/06/2014 18:29:46
14 --- 05/06/2014 18:29:56
15 --- 05/06/2014 18:30:07
16 --- 05/06/2014 18:30:09
17 --- 05/06/2014 18:30:15
18 --- 05/06/2014 18:30:32
19 --- 05/06/2014 18:30:52
20 --- 05/06/2014 18:30:54

Note the logged "Misfire" after the 13th entry.  This shows the script tried to run again with blank post data, the same problem I'm having in my more complex script.

Why could this be happening? It's not anyone else calling the script, nobody knows about the site and I've ruled it out by logging the IP in my real script.

 <td> <button onclick="alertdialog()"><span class="glyphicon glyphicon-trash"> </span></button></td>
<script>
function alertdialog(){
    window.confirm("Are you sure you want to delete this post?");
}
</script>   This is my code. I need to have a callback to a PHP script when a user decides to delete a post. I think html POST is the most unobtrustive way to do this. What's the easiest / most robust way to send data to a script when the user clicks OK?   Appreciated. Mark  

ok..ive done this a million times..i have a working example here and i copied it and amended it for this new project but for some reason i cant get a form to post data to another page.

this is the error message i get

Notice: Undefined index: username in C:\wamp\www\uni\fyp\site\mobile\login.php on line 16

Notice: Undefined index: password in C:\wamp\www\uni\fyp\site\mobile\login.php on line 17

here is my form code:

                    <form method="post" action="login.php">
                        <table align="center" cellpadding="0" cellspacing="0">
                        <tr>
                            <td style="vertical-align:top;">Username:&nbsp; </td><td><input type="text" name="username" value="" /></td>
                        </tr>
                        <tr>
                            <td style="vertical-align:top;">Password:&nbsp; </td><td><input type="password" name="password" value="" /><br /><input type="submit" id="submit" value="Login" /></td>
                        </tr>
                        </table>
                    </form>


and here is the code within the login.php where the form should post to

$username = $_POST['username'];

$password = $_POST['password'];

// Help protect against MySQL injection

$username = stripslashes($username);

$password = stripslashes($password);

$username = mysql_real_escape_string($username);

$password = mysql_real_escape_string($password);

// Selecting data from database where correct username and password are found

$sql="SELECT * FROM customer WHERE username='$username' and password='$password'";

$result=mysql_query($sql) or die(mysql_error());



i cant see anything wrong..been looking for hours...please please help me

Hi all,

Thanks for reading. I'm hella frustrated at this script I wrote: for some reason, it will not work correctly.

Basically, it works. The first 4 names in the table on the database show up when searched. But, anything past these four names in the database will not show up as a result when searched! I'm pulling my hair out here!

It's really simple - take a gander:

Code: [Select]
if (isset($_POST['submit'])) {

$search = $_POST['search'];

$searchQuery = mysql_query("SELECT * FROM Accounts WHERE FullName='$search'");

if (mysql_num_rows($searchQuery) == 0) {
$result = "Your search returned no results. Please try again.";
} else {

$results = 1;

while ($getSearchResults = mysql_fetch_array($searchQuery)) {

$fullName = $getSearchResults['FullName'];

$result = "Name: ".$fullName."";

}

}

}

?>

...and the HTML form...

Code: [Select]
<form action="search.php" method="post">

<p>Search: <input type="text" name="search" size="35" maxlength="100" /></p>
<p><input type="submit" value="Search" name="submit" /></p>

<?php echo $result; ?>

</form>

Does anyone have any ideas?
