PHP - Fluent Interface Method Call In An If Statement

class MyDisplay 
{

function displayToday()
	{
		
		$today = "Thursday";
		{
		echo $today;
		}
		
		
	}
function displayTomorrow()
	{
		
		$tomorrow = "Friday";
		{
		echo $tomorrow;
		}
		
		
	}

}


$disp = new MyDisplay();


echo $disp->displayToday();
echo displayTomorrow();//fails is I have $disp->

I simplified my code for explanation. One class with two methods. When I try to use the method I get this error. Fatal error: Call to undefined method MyDisplay::displayTomorrow()

HI guys,
 i am using 'Spreadsheet excel writer' to write form data into an excel sheet.

 below is my code snippet, uses to add worksheets, iam getting an error, which is really breaking me.
can u please have a look at this, and help me.
Code: [Select]
<?php
$xml = simplexml_load_file("featureDetail.xml");
require_once 'Spreadsheet/Excel/Writer.php';
$excel = new Spreadsheet_Excel_Writer();
$sheet =& $excel->addWorksheet('Home');
$sheet->setColumn(0,0,29);
foreach($xml->FEATURE as $feature)
{
global $excel;
$value=html_entity_decode($feature->NAME);
echo " Value = $value";
echo "<br>";
$sheet123 =& $excel->addWorksheet('$value');
$sheet123->setColumn(0,0,29);
}
foreach($xml->FEATURE as $feature)
{
$sheet =& $excel->addWorksheet(html_entity_decode($feature->NAME));
$sheet->setColumn(0,0,29);
}
?>

Fatal error: Call to undefined method PEAR_Error::setColumn() in D:\xampp\htdocs\Release9.0\example.php on line 14

So I have this code that generates a random ID

class Session
{
   var $username;     //Username given on sign-up
   var $userid;       //Random value generated on current login
...
...
   function Session(){
      $this->time = time();
      $this->startSession();
}

...
...

$this->userid    = $_SESSION['userid']   = $this->generateRandID();

...
...

   function generateRandID(){
      return md5($this->generateRandStr(16));
   }


and when it runs i get this error...
Fatal error: Call to undefined method Session::generateRandID()

Any ideas?

Hello,

I have no idea where to post this but basically I am trying to create a facebook application using a "Building Facebook Applications For Dummies" book but I am stuck on the first paragraph! This is the appinclude.php file:

Code: [Select]
<?php
require_once '../client/facebook.php';

// *** Add your Facebook API Key, Secret Key, and Callback URL here ***
$appapikey = '<xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx>';
$appsecret = '<xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx>';
$appcallbackurl = '<http://projectstratos.com/facebook/live/>';  

// Connect to Facebook, retrieve user 
$facebook = new Facebook($appapikey, $appsecret);
// $user = $facebook->require_login(); OLD 
$user = $facebook->get_loggedin_user(); 
$is_logged_out = !$user; 

// Exception handler for invalid session_keys 
try {
  // If app is not added, then attempt to add 
  if (!$facebook->api_client->users_isAppAdded()) {
    $facebook->redirect($facebook->get_add_url());
  }
} catch (Exception $ex) {
  // Clear out cookies for app and redirect user to a login prompt
$facebook->set_user(null, null);
$facebook->redirect($appcallbackurl);
}
?>
And this is the index.php file:
Code: [Select]
<h1>Watch Project Stratos Live!</h1>
<?php
require_once 'appinclude.php';

echo "<p>Your user id is: $user</p>";
echo "<p>Your name is: <fb:name uid=\"$user\" useyou\"false\" /></p>";

echo "<p>You have several freinds: </p>";
$friends = $facebook->app_client->friends_get();
echo "<ul>";
foreach ($friends as $friend) {
echo "<li><fb:name uid=\"$freind\" useyou\"false\" /></li>";
}
echo "</ul>";
?>
The facebook.php is the current fbml version (v2.1.2-4 I think) and the content in the h1 tag is echoed however after that there is the following errror message:

Code: [Select]
Fatal error: Call to undefined method Facebook::get_loggedin_user() in /xxxxxx/xxxxxx/xxxxxx/xxxx/xxxxxxxxxxxxxxxxxxxxxx/facebook/live/appinclude.php on line 12
I have mo idea what the problem could be! I have tried changing get_loggedin_user to getUser() but I just get another error, this is aparently (according to another forum) because I "forgot" to add get_loggedin_user.

Thanks in advance,
Cameron

Hello,

I've been following google maps with php/mysql turorial http://code.google.com/apis/maps/articles/phpsqlajax.html

I've come to my phpsqlajax_genxml.php file which as the google code has it like this:

<?php
require("phpsqlajax_dbinfo.php");

// Start XML file, create parent node
$doc = domxml_new_doc("1.0");
$node = $doc->create_element("markers");
$parnode = $doc->append_child($node);

// Opens a connection to a MySQL server
$connection=mysql_connect (localhost, $username, $password);
if (!$connection) {
  die('Not connected : ' . mysql_error());
}

// Set the active MySQL database
$db_selected = mysql_select_db($database, $connection);
if (!$db_selected) {
  die ('Can\'t use db : ' . mysql_error());
}

// Select all the rows in the markers table
$query = "SELECT * FROM markers WHERE 1";
$result = mysql_query($query);
if (!$result) {
  die('Invalid query: ' . mysql_error());
}

header("Content-type: text/xml");

// Iterate through the rows, adding XML nodes for each
while ($row = @mysql_fetch_assoc($result)){
  // ADD TO XML DOCUMENT NODE
  $node = $doc->create_element("marker");
  $newnode = $parnode->append_child($node);

  $newnode->set_attribute("name", $row['name']);
  $newnode->set_attribute("address", $row['address']);
  $newnode->set_attribute("lat", $row['lat']);
  $newnode->set_attribute("lng", $row['lng']);
  $newnode->set_attribute("type", $row['type']);
}

$xmlfile = $doc->dump_mem();
echo $xmlfile;

?>


I started with this but was getting errors at line 1!! I looked around abit on the net and found i should change

$doc = domxml_new_doc("1.0");

to this

$doc = new DOMDocument('1.0');

Then i got errors abour creating the elements, i looke on php.net and it looked like i needed to change

$node = $doc->create_element("markers");
$parnode = $doc->append_child($node);
$newnode->set_attribute("name", $row['name']);


To this:

$node = $doc->createElement('markers');
$parnode = $doc->appendChild($node);
$newnode->setAttribute ('name', $row['name']);

This at least got my code further down the page until the very last statment:

$xmlfile = $doc->dump_mem();

Here i'm getting this error "Fatal error: Call to undefined method DOMDocument::dump_mem()" along with "Warning: Cannot modify header information - headers already sent"

I havent even looked at the warning i just tried to fix the fatal error. Again i looked around the web and forums and php.net and thought maybe i need to set the value to "true" but it still got a fatal error.

I looked on php.net and in there examples for dump_mem() and they had the nodes set_attribute create_element and append_child.

Which confused me as that was what i used originally just following the google script and that got me the error right away "Fatal error to undefined method DOMDocument::create"


Can anybody point out whats going wrong? This is my script that I am using

<?php
require('connect.php');
?>

$newnode->setAttribute ('lat', $row['lat']);

$newnode->setAttribute ('type', $row['type']);
}

$xmlfile = $doc->dump_mem();
echo $xmlfile;
?>

</body>

</html>


And the google code is on the link in posted in the messge also but this is theres both of which fail for Fatal errors either on the dump_mem() or new DOMDocument respecitvaley :

<?php
require("phpsqlajax_dbinfo.php");

Thanks to anybody who can help me out 

Hi all,

I've been struggling to get an if statement to work. I'm new to PHP so bear with me!

I have an events listing page where I pull a value from a custom field to display a 'buy tickets' button. I can get the button to display and it works well but what I need to do is customise the code so if there is no ID present, then a piece of text displays. Any pointers appreciated.

This is one method Im using for custom fields which works well - the if statement works here also.
Code: [Select]
<div>
      <p><strong>Location:</strong>
        <?php $event_location = get_post_meta($post->ID, 'Event_Location', true);
if ($event_location) {
?>
        <?php echo $event_location; ?>
        <?php } else { ?>
      <p>No Location Available.</p>
      <?php } ?>
      </p>
    </div>
This code pulls in the buy tickets button but I cant figure out how to create an if statement with it! grrrr...

Code: [Select]
<div>
      <p>
    <?php
 $values = get_post_custom_values('Product_ID');
echo get_button_code_for_product($values[0]);
?>
      </p>
    </div>
I would like it to look for the ID and if it can't find it then displays ' No Product ID' or some such text.

If a class has a constructor but also has a static method, if I call the static method does the constructor run so that I can use an output from the constructor in my static method?

--Kenoli

I have two classes:

## Admin.php

<?php
class Admin
{
public function __construct()
{
include("Config.php");
}

/**
* deletes a client
* @returns true or false
*/
function deleteClient($id)
{
return mysql_query("DELETE FROM usernames WHERE id = '$id'");
}
}
?>


## Projects.php

<?php
class Projects
{
public function __construct()
{
include("Config.php");
$this->admin = $admin;
$this->dataFolder = $dataFolder;
}

/**
* Deletes a project
* @returns true or false
*/
function deleteProject($id)
{
$root  = $_SERVER['DOCUMENT_ROOT'];
$theDir  = $root . $this->dataFolder;
$sql  = mysql_query("SELECT * FROM projectData WHERE proj_id = '$id'");
while ($row = mysql_fetch_array($sql))
{
$mainFile = $row['path'];
$thumb = $row['thumbnail'];
if ($thumb != 'null')
{
unlink($theDir . "/" . substr($thumb,13));
}
unlink($theDir . "/" . substr($mainFile,13));
}
$delete = mysql_query("DELETE FROM projectData WHERE proj_id = '$id'");
$getDir = mysql_query("SELECT proj_path FROM projects WHERE id = '$id'");
$res = mysql_fetch_array($getDir);
rmdir($theDir . "/" . $res['proj_path']);
return mysql_query("DELETE FROM projects WHERE id = '$id'");
}
}
?>


How can I call deleteProject() from within Admin.php?

 

My script has 3 classes (that are relevant to this discussion): DB, User and Validate. They are all in independent files and loaded automatically, when required, by an autoloader.
Both the User class and the Validate class have a private variable $_db which is instantiated by their class constructor: $this->_db = DB::getInstance();
At the top of the script I declare new instances: $user = new User(); and $validate = new Validate();
I then call a method in $user: $found = $user->findInUsers ( .... )
From within the findInUsers method I then want to call the query method in the DB class. My problem is that I can't find a way to do this that works.
I have tried $this->_db->query( ... ), $_db->query( ... ), but neither works.

The error messages I am getting a
An error occurred in script '/srv/http/classes/User.php' on line 42: Undefined variable $_db
Uncaught Error: Call to a member function query() on null in /srv/http/classes/User.php:42

Any pointers as to what I am doing wrong, or what I should be doing, would be most welcome.

I am just starting out with PHP.  I have resorted to doing some custom PHP programming because the plug-INs for a CMS I am using need a little customization.

The question I have is very simple and I am sure PHP programmers can answer this instantly.  I have successfully declared a global PHP variable.  All I need to know how to do for now is how to declare a button or a hyperlink or an input form element such that it can change the assignment of this variable.

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.

Hello,
I use loads of different servers at work and they all run seperate services that I need to keep my stuff running.
I want to build a simple webpage that will poll the services and display the current state by colour.  EG have table that lists the services in green and have them turn red if the service stops unexpectedly.

I can build the tables and stuff, I just don't know how to retrieve the state of a service.  I've been messing about with some ideas but nothing is working.

eg lets say I have two servers each with one service:

service one | IP Address of server | RUNNING service two | IP Address of server | STOPPED
Has anyone got any ideas?

Thanks!!
