PHP - Call Functions

This topic has been moved to Other Libraries and Frameworks.

http://www.phpfreaks.com/forums/index.php?topic=319682.0

OVERVIEW:

The code is about making call to the escreen web service using SOAP and Curl with client authentication required. Currently I am not getting any result only HTTP 403 and 500 errors.
The call requires client authenticate cert to be on the callng site.

CODE:

    $content = "<TicketRequest>
      <Version>1.0</Version>

QUESTIONS:

1. I need to call the RequestTicket method and pass the XML string to it.
   I don't know how to do it here(pass the method name to call).

2. For client authentication they gave us three certs, one root cert, one intermediate
   cert and a client authentication cert PROTPLUSSOL_SSOpem(it was a .pfx file). Since we are on linux we converted them to pem . In curl calls I could not find way to how to include both the root cert and the intermediate cert ,so I combined them by making a new pem file and copying the intermediate cert and them the root cert and naming it authority.pem .
I am not sure whether it works or not and would like your opinion.

3. For the current code Iam getting the error
   Error no : 77 Curl error: error setting certificate verify locations: CAfile: /home/pps/authority.pem CApath: /home/pps/

 
  If I disable the curl error message,I am getting blank page with page title 403 - Forbidden. Access is denied.

  If I comment out the CURLOPT_CAPATH and CURLOPT_CAINFO lines it gives http 500 error page with the message as content and the following at the top.

 > HTTP/1.1 500 Internal Server Error. Cache-Control: private Content-Type: text/html Server: Microsoft-IIS/7.5 X-AspNet-Version: 1.1.4322 X-Powered-By: ASP.NET Date: Thu, 02 Sep 2010 14:46:38 GMT Content-Length: 1208

If I comment out as above and also CURLOPT_SSLCERT and CURLOPT_SSLCERTPASSWD it gives 403 error with the message as content.

So I would request you to help me out by pointing out whats wrong with the current code.

Thank you.

I can call the following function successfully as a single php program

  // Acknowledge and clear the orders
   function ack($client, $merchant, $id) {
         $docs = array('string' => $id);
         $params = array('merchant' => $merchant, 'documentIdentifierArray' => $docs);
         $result = $client->call('postDocumentDownloadAck', $params);
         return $result;
         }
with

   $result = ack($t, $merchant,'2779540483');

successful output

    [documentDownloadAckProcessingStatus] => _SUCCESSFUL_
    [documentID] => 2779540483

I'm trying to figure out how to call this function as an object from another program.

Trying the following gives error  ***Call to a member function call() on a non-object***

  function postDocumentDownloadAck($t, $merchant, $id) {
     $this->error = null;
     $docs = array('string' => $this->id);
     $params = array('merchant' => $this->merchant, 'documentIdentifierArray' => $docs);

 **  I've tried the following which does nothing
     $result = $this->soap->call('postDocumentDownloadAck', $params);

** I've tried the following   -  which gives error "Call to a member function call() on a non-object"
     $result = $this->t->soap->call('postDocumentDownloadAck', $params);

     if($this->soap->fault) {
        $this->error = $result;
        return false;
     }

     return $result;
  }


***

calling program snippet for above function
   $merchant= array( "merchant"=> $merchantid, "merchantName" => $merchantname, "email"=> $login, "password"=> $password);
   $t = new AmazonMerchantAPI($merchantid, $merchantname, $login, $password);
   $documentlist= $t->GetAllPendingDocumentInfo('_GET_ORDERS_DATA_');
   $docid = $documentlist['MerchantDocumentInfo'][$i]['documentID'];
   $docs = array('string' => $docid);
   $ackorders = $t->postDocumentDownloadAck($t, $merchant,$docs);

Any ideas of what I'm doing wrong are greatly appreciated.

I have a script I am putting together that simulate a cricket game. The only issue is, that there are a huge number of functions because there doesn't seem to be any other way to do this properly. As well as this, there a while() loop and all this seems to be leading to the page reaching a max 30 second timeout when generating the result.

My code is attached below, it is quite messy at the moment because i've just be working on it, but I was wondering if anyone has any solutions of how I can speed this up or change to prevent a timeout:

Hello,

I've been trying this for hours now, looking at different examples and trying to change them to work for me, but with no luck...

This is what I am trying to do:

I have a simple form with:
- 1 input field, where I can enter a number
- 1 Submit Button

When I enter a number into the field and click submit, I want that number to be send to the php file that is in the ajax call, then the script will take that number and run a bunch of queries and then return a new number. I want that new number to be used to call the php script via ajax again, until no number is returned, or something else is returned like the word "done" or something like that, at which point is simply makes an alert or populated a div with a message...

The point is, that depending on the number entered it could take up to an hour to complete ALL the queries, so I want the script that is called to only run a fixed amount of queries at a time and then return the number it is currently at (+1), so that it can continue with the next number when it is called again.

I would like to use jquery, but could also be any other way, as long as I get this to work. I already have the php script completed that needs to be called by the ajax, it returns a single number when being called.

Thank you,
vb

I teaching myself php, but I am coming from java and other compiled languages, so the process has been a little bumpy. I am trying to do something like this:

Code: [Select]
class my_class
{

  function one ()
  {
     $two = two ();

     $three = three ();

     $five = $two + $three;

     return $five;
  }

  function two ()
  {
     $two = 2;

    return $two;
  }
 
  function three ()
  {
     $three = 3;

     return $three;
  }
}


Unfortunately, I keep getting an error message saying that my call to two () is an undefined function. I am gathering from this that the scope of one () is not aware of the existence of two (). Is there a way to get around this so I can call two () and three () from one ()?

When in OOP I have been watching tutorials and some have functions just written like Code: [Select]
class user
{
 public $user;

 public function __construct($u)
 {
   $this->user = $u;
 }

}
do I need to type public before the function or is it better practice to just put

Code: [Select]
class user
{
 public $user;

 function __construct($u)
 {
   $this->user = $u;
 }

}


Thanks!

Hi,

I've got 3 different upload forms in one form.  I'm making a function so it just one piece of code.

I'm having a bit of a problem changing some of the code so it works for all 3.

Here is the function




function loadImages ($action, $position)
{
 $link = mysql_connect("","","");
if (!$link)
{
die('Error: could not connect: ' . mysql_error());
}

$db_select = mysql_select_db("",$link);
if (!$db_select)
{
die ("Error: database selection failed: " . mysql_error());
}
$page = ($_POST["pageName"]);
if ((($_FILES["bfile"]["type"] == "image/gif")
|| ($_FILES["bfile"]["type"] == "image/jpeg")
|| ($_FILES["bfile"]["type"] == "image/pjpeg"))
&& ($_FILES["bfile"]["size"] < 9000000))
{
if ($_FILES["bfile"]["error"] > 0)
{
echo "Return Code: " . $_FILES["bfile"]["error"] . "<br />";
}
else
{
 $success = '<p style="font-weight: bold; color: #C00">Upload successful<br />';
// move uploaded temporary file to final destination
move_uploaded_file($_FILES["bfile"]["tmp_name"],
"uploads/" . $_FILES["bfile"]["name"]);

// update database with new filename
 $filename = $_FILES["bfile"]["name"];
 $sql = "UPDATE images 
 SET filename= '$filename'
 where page = '$page'
 and position = '$position'";

if (!mysql_query($sql,$link))
{
die('Error: ' . mysql_error());
}

}
}
else
{
 $fail = '<p style="font-weight: bold; color: #C00">Invalid file';
}
mysql_close($link);
}


Now the $action is the bit that will determine whether it's updateTop updateMiddle or updateBottom.  $position finds out if it's top middle or bottom


if (isset($_POST['updateTop'])) 
    {
loadImages ($_POST['updateTop'], "top");
}


Here is a sample of the html, it's in a switch

case "Products":
                              echo "<p>Image Top</p>
                                    <input type=\"file\" name=\"file\" id=\"file\" />  <input type=\"submit\" name=\"updateTop\" value=\"Update $page Top\" />
                                    <p>Image Middle</p>
                                    <input type=\"file\" name=\"mfile\" id=\"mfile\" />  <input type=\"submit\" name=\"updateMiddle\" value=\"Update $page Middle\" />
                                    <p>Image Bottom</p>
                                    <input type=\"file\" name=\"bfile\" id=\"bfile\" />  <input type=\"submit\" name=\"updateBottom\" value=\"Update $page Bottom\" />
                                    ";
                              break;


What I need to do is get $_FILES["bfile" into a variable to see whether it's "bfile" "mfile" or "file" but not sure how to write it.

Thanks for the help.

i am wondering what the '@' is used for when used in front of a function like


Function(@$VAR);


What is the benefit of the @?

OK, so if I've got this in my one of my class files:
public function userr($user)
{

$thisquery = mysql_query("SELECT * FROM users WHERE username='". $user ."'");
if(mysql_num_rows($thisquery) == 1)
{
return true;
}

return false;
}

Could I use something like this:
if($class->userr($user)) { // Something } 
If not, how would I go about doing something like it?

And is there any way I could use a mysql_fetch_assoc in a function?

Can someone tell me by looking at the following code why function pcust() does not work, I am new to programming? 


Code: [Select]
$firstname = "chris";
$surname = "reynolds";
$address1 = "12 birch end";
$town = "Wallington";
$county = "surrey"; 
$postcode = "wh20 3bg";
$telephone = "01372 854785";
$cust_details = fix_cust($firstname, $surname, $address1,$town, $county, $postcode,  $telephone   );
function fix_cust($n1, $n2, $n3, $n4, $n5, $n6, $n7)
{
$n1 = ucfirst(strtolower($n1));
$n2 = ucfirst(strtolower($n2));
$n3 = ucwords(strtolower($n3));
$n4 = ucfirst(strtolower($n4));
$n5 = ucfirst(strtolower($n5));
$n6 = ucfirst(strtoupper($n6));
$n7 = ucfirst(strtolower($n7));
return array($n1, $n2, $n3, $n4, $n5, $n6, $n7);


}


echo $cust_details[0] . " " . $cust_details[1];
echo "<br />";
echo $cust_details[2];
echo "<br />";
echo $cust_details[3];
echo "<br />";
echo $cust_details[4];
echo "<br />";
echo $cust_details[5];
echo "<br />";
echo $cust_details[6];
echo "<br />";

function pcust(){
$length = count($cust_details );
for ($i = 0; $i < $length; $i++) {
  echo $cust_details[$i];
  echo "<br />";
}
}
pcust();

As painfully simple as this may be, I seem to be doing something wrong as always. New to php and decided to start using functions. I'm trying to add functions from an external functions.php file to my other pages and then call the functions where necessary. How should I go about it? I tried something like this:

Functions.php:
Code: [Select]
<?php
function field() {
echo 'text heherh';
}
?>

and then when calling it to when needed for example:
include 'includes/functions.php'; // at the top of the page
Code: [Select]
<?php
// and when trying to call the function on a specific line 
if (!$sname)
$errorstring = $errorstring . "<b>Surname:" . field() ; //field being the function name
?>

I know this is very simple but I have never used functions before.. tried google, didn't help much and I'm pressed for time so decided to ask here. Thanks in advance

I have a function for mysqli_real_escape_string above this function and it works with no errors.

Have i done something wrong? as you can see i am including the file which holds the connection but it doesnt seem to use it. every other file that uses the connection works fine.

Hi, I could use a little guidance here. 1) is a function with
values to be sent to 2).

1) <!-- use ajax - OnCalc function to send data to your database. -->
function OnCalc(value1,op,value2,total)
  {

2) php file using above function values
<?php
  header( "refresh:5;url='http://localhost/hom...lcprint.php'");
  echo 'You\'ll be redirected in about 5 secs. If not, click <a

href="http://localhost/hom...hp">here</a>.';

echo '<script type="text/javascript">'
   , 'OnCalc();'
   , '</script>';
No error but code not working?

Hey guys.
Can anyone tell me what this means?
function foo 
{
}


It is basic php but I don't get it. Should it be called for execution, or does it work automatically, or both?
The php manual at w3schools and php.net are too tough for me. That's why I posted here.

Thanks!
