PHP - This Class Is Killing Me. Constructor Runs, Does Not Set Values To Variables.

Hi,

I need to be able to call a class based on variables.  E.G.

I would normally do:
Code: [Select]
$action = new pattern1()
but i would like to be able to do it dynamicaly:
Code: [Select]
$patNum = 1;
$action = new pattern.$patNum.()
Im wondering if that's possible?  If so what would the correct syntax be?

Many Thanks.

I am getting the following error:

Parse error: parse error, expecting `T_OLD_FUNCTION' or `T_FUNCTION' or `T_VAR' or `'}'' in /Library/WebServer/Dev/classtest/lib/class_userdata.php on line 5

on this class code:

Code: [Select]

class userdata {

public $name = "";
public $city = "";
public $phone = "";

function setData($n, $c, $p) {

$name = $n;
$city = $c;
$phone = $p;

}

function getData() {

$userdata=array('name'=>$name, 'city'=>$city, 'phone'=>$phone);
return $userdata;

}

}


I thought that was a proper way to set up some class variables. (http://www.victorchen.info/accessing-php-class-variables-and-functions/). Thanks.

Does anyone know if it's possible to call a class with an arbitrary number of variables?  I'll explain what I mean.
Here is my class construct definition:
Code: [Select]
function __construct($file, $outFile = 'newpdf.pdf', $fontSize = 70, $alpha=0.6, $overlayMsg = 'N O T  F O R  S H O P', $degrees = 45) {
I know that I have to pass over the $file variable for it to work now.  But can I create the class passing just the $file var and the $overlayMsg var?  Everything else I would want to leave as default.  How would I do that?
Thanks
Mike

I think I need to use $this, but I need to be able to add the two values returned from both of my functions.  How would I do that?

Code: [Select]
public function get_users_edge($uid)
{
$users_primary->get_users_primary_edge($uid);
$users_dynamic->get_users_dynamic_edge($uid);

echo $users_primary + $users_dynamic;
}

I keep running into a bunch of error when I  declare the page variable in my model.  What syntax do I need to use throughout the class?

Code: [Select]
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Header_Model extends CI_Model{

var $page = substr(end(explode(DIRECTORY_SEPARATOR, $_SERVER['PHP_SELF'])), 0, -4);

function get_page_name()
{
$this->load->library('common');

$page_names = $this->common->page_names();

$title = (array_key_exists($page, $page_names) !== false) ? $page_names[$page]: '';

if (array_key_exists($page, $page_names) !== false)
{
$title .= " | Jason Biondo";
}

return $title;
}

function get_js_page_file()
{
if (file_exists("./assets/js/pages/${page}.js"))
{
$javascript = "<script type=\"text/javascript\" src=\"./js/pages/${page}.js\"></script>";
}

return $javascript;
}

}

What would be the simplest way? Do you use a method in the child class?

Personally I use

Code: [Select]
parent::$this->whatever;

But I was wondering what you guys do.

I'm looking for a more efficient way of declaring variables within a class. What I normally use is a class which is actually a database object. Every time I make a new table in my database I make a new class and new attributes to match the fields in the db table. Looks something like this:

    Code: [Select]
protected static $table_name="myTable";
protected static $db_fields=array('id', 'name', 'address', 'tel_number', 'fax_number');

public $name;
public $address;
public $tel_number;
public $fax_number;

//etc. etc.
At the moment I am manually adding the attribute, everytime I add a field to the db table. I'm guessing there should be a way to loop through the $db_fields array and add an attribute in the loop? Can anyone help me with the syntax for this. Is there also a way that I don't have to list the fields everytime in $db_fields....can $db_fields not just look at the relevant db table and pull out the field names in some kind of clever method?

I'm confused as to why assigning these variables in the class causes the page not to load...


var $RootFolder = '/shyid/';
var $PagePath = str_replace($this->RootFolder, '', dirname($_SERVER['PHP_SELF']));
var $PageSections = explode('/', $this->PagePath);


but when i set them on the page, everything works correctly?


$head->RootFolder = '/shyid/';
$head->PagePath = str_replace($head->RootFolder, '', dirname($_SERVER['PHP_SELF']));
$head->PageSections = explode('/', $head->PagePath);


Insight? Thanks.

All my code is returning is the username... Please help.   index.php

<?php

include('user.class');
$user = new user("Jbonnett", "0", "Admin", "Jamie", "Bonnett", "jbonnett@site.co.uk", "01/09/1992");

echo "username: " . $user->getUsername() . "<br/>";
echo "id: " . $user->getId() . "<br/>";
echo "level: " . $user->getLevel() . "<br/>";
echo "Forename: " . $user->getForename() . "<br/>";
echo "Surname: " . $user->getSurname() . "<br/>";
echo "Email: " . $user->getEmail() . "<br/>";
echo "Dob: " . $user->getDob() . "<br/>";


?> 

user.class 

<?php

class user {
	
	private $username;

hi,
i have a class file that have all values from a database fields.
for example:


 class mospedidos extends mosDBTable {
id = null;
date =null;
}

 class mosunder extends mosDBTable {
id = null;
name =null;
}

each time i creat a new field in the database i need add the same field in the
class file, what i want is a way using  php to add that new field to the class file.
i just need a way to open the file and the class name that i give and add the value
and save the file.
how can i do this?
thanks for your help

Hi,

I have a string with the value of

{ "success": true, "delivered": true, "contactDetailsRequired": false, "message": "Signed For by: D ANDERSON ", "signature": "https://webservices.thedx.co.uk/PodImage/ImageHandler.ashx?tn=906732192165", "date": "21-07-2020", "serviceLevelName": "Consigned", "time": "13:33:19", "trackedProductName": "DataExchange" }

How do i go about placing the values into variables so for example:

$success = "true";
$delivered = "true";
$message = "Signed for by: D ANDERSON";
etc....

My mind has gone blank and im having one of those days, any help would be greatly appreciated. Thanks

Hi guys, I am trying something fairly simple but I'm not sure if this would be a good practice. Basically I am using a big class called CommonLibrary that holds common functions as methods and common variables as static variables. But I have some variables here and there like $allAlphabet = range ('a' , 'z'), that cannot be declared as a property because it gives me a parse error.

I don't want to call an object for this class because instancing it is of no use. Values will never change with regards to instances. So the next best thing that I tried was declaring all static variables first, and then changing thei property values inside the class __construct with self::$variable = 'somevalue', and then using this code below to assign values to the empty static variables.


$dummyObject = new CommonLibrary;
unset($dummyObject);
echo CommonLibrary::$staticVariable; // This property is NULL before the constructer is triggered.


Anyone recommend any better ways of doing this?

Thanks in advance!

Hi I am adapting Jeffery Ways Mysql class to accept multiple where statements however I have got stuck on the final hurdle.
It is when I try to do the bind_results() and I pass in the parameter types and the parameters. Here is that part of the code:

if ($this->_where)
            $values = array_values($this->_where);

         $str = "'";
             $str .= implode('\', \'', $values);
            $str .= "'";
            // echo $str;
         $count = count($this->_where);

         foreach($this->_where as $key => $value){
             $key = $value;
         }
         $user = 'matt25';
         $pass = '6722853cacc4a9649dc75abc852f23c35b1f75cb';

         $stmt->bind_param($this->_paramTypeList, $user, $pass);
      }

It works how it is by setting the parameters as variables, but that obviously isn't practical. as you can see I also tried to make a string with the values from the array which brought up the error:
 Warning: mysqli_stmt::bind_param() [mysqli-stmt.bind-param]: Number of elements in type definition string doesn't match number of bind variables in C:\wamp\www\trick_tips\admin\includes\MysqlDb.php on line 260,

the same as when I try to put the array into there.

So I need some way of setting each value in the array as a variable to then put into the function, or another Idea that I have completely missed.

Any help would be much appreciated.

Cheers,
Matt

Hi all,

I am having some trouble with a script.. all works fine except for the calculation part. It isn't adding up, but the reason for this is because when I echoed all the variable it seems that they are blank, the problem is I can't figure out why?

<?php
    # you don't display errors on in-use scripts, do you?
    ini_set('display_errors',0);

            </label>
    </li>
";
}

// remainder of script here
?> 

The ones that are returning blank a

$result and $votes

$results should be the number of votes a specific option has received while $votes is the total number of votes in the whole poll.

My database contains the following data...

QID AID votes
685b9628ca340529fa54208c65721dd7 2 205
685b9628ca340529fa54208c65721dd7 0 5
685b9628ca340529fa54208c65721dd7 1 2

It's from the following tutorial - http://net.tutsplus.com/tutorials/ph...poll-with-php/

Can anyone advise me here?

Many thanks,

I want to create an application for sending mails using PHPMailer by placing it on my website

server (using SMTP),
but I can not get object of class phpmailer to change its properties of:

to_name
to_email
ContentType

from default (i.e. null).
Why are the properties keeping default values from the PHPMailer class, and not accepting my

once, though I check values i get from DB and they are good. ContentType is set in a config file.


Here is part of var_dump ($mailer); object of my extended class:
object(MyMailer)#2 (56) { ["priority"]=> int(3) ["to_name"]=> NULL ["to_email"]=> NULL ...
["ContentType"]=> string(10) "text/plain"...

also I get value of ["Port"]=> int(26) but ["SMTP_PORT"]=> int(25).
I need to use smtp port  26.


And here is the extended class of phpmailer

require_once './PHPMailer/class.phpmailer.php';
require_once 'mailer-config.php';

class MyMailer extends PHPMailer
{
    var $priority = 3;
    var $to_name = null;
    var $to_email = null;
    var $From = null;
    var $FromName = null;
    var $Sender = null;
    var $ContentType = null;
   
    function MyMailer()
       {
       global $eSlanje;
       
       // Comes from mailer-config.php $eSlanje array
       
        if($eSlanje['smtp_mode'] == 'enabled')
           {
            $this->Host = $eSlanje['smtp_host'];
            $this->Port = $eSlanje['smtp_port'];
            if($eSlanje['smtp_username'] != '')
               {
                $this->SMTPAuth = true;
                $this->Username = $eSlanje['smtp_username'];
                $this->Password = $eSlanje['smtp_password'];
               }
            $this->Mailer = "smtp";
           }
        if(!$this->From)
           {
            $this->From = $eSlanje['from_email'];
           }          
        if(!$this->FromName)
           {
            $this->FromName = $eSlanje['from_name'];
           }
        if(!$this->Sender)
           {
            $this->Sender = $eSlanje['from_email'];
           }
        $this->Priority = $this->priority;
        //echo "<br>eSlanje[content_type]";
        //var_dump ($eSlanje['content_type']);
       $this->ContentType = $eSlanje['content_type'];   
       }
}

and here is the cofig file:

mailer-config.php

<?php
$eSlanje['from_email'] = "hi@mysite.com";
$eSlanje['from_name'] = "Joe Blog";
$eSlanje['title'] = "hi there";
$eSlanje['content_type'] ="text/html";

$eSlanje['smtp_username'] = null;
$eSlanje['smtp_mode'] = "enabled";
$eSlanje['smtp_port'] = 26;
$eSlanje['smtp_host'] = "mail.mysite.com";



Here is where I insert values of email and name into the object:
<?php session_start();
   include ("password.php");
   require_once 'class_lib/MyMailer.php';
   require "class_lib/MySQL_Database.php";
   require "get_email_template.php";
   
   $db = new MySQL_Database ();
   
   $id = isset($_GET['id']) ?  $_GET['id'] : false;
   $sql = "select email,ime from ".TABLE." where id = $id";
   $query = mysql_query ($sql);
   $toClient = mysql_fetch_array($query);
   
   $to = isset($toClient['email']) ? $toClient['email'] : false;

   var_dump($to); // here I get a valid email address

   $to_name = isset($toClient['ime']) ? $toClient['ime'] : false;

   //var_dump($to_name); // here I get a valid preson's name
   
   $mailer = new MyMailer();
   $mailer->AddAddress($to, $to_name);
   $mailer->Body = get_htmlBody();
   $mailer->AltBody = get_txtBody();
   if(!$mailer->Send())
      {
      echo "<br> Mailer Error: " . $mailer->ErrorInfo."&nbsp";   
      }
      else {
         echo "<br>message not sent &nbsp";
         }
   $mailer->ClearAddresses();
            
   var_dump($mailer); // this is where the object trace comes from
?>
