I closed everything down last night and it was all fine, website was working as normal etc, but I've turned on the Xxamp server today and I am getting this error. Seems very random as nothing has changed since it was last on? 

Does anyone know how to sort this out and why I'm now getting this error? Thanks!

would anyone know how to assign the value (value returned by some function in the class) of variable $temp in the class: source looks like:

class newRecord{
var $temp = listCat('gallery_menu', 'submenu', 'submenu_id'); ////// this line is not working, does not assign?

function listCat($table, $submenu, $submenu_id)
{
$return = '<select name="'.$submenu_id.'" id="'.$submenu_id.'">';
$result = mysql_query("SELECT * FROM $table");
while($row=mysql_fetch_object($result))
{
$return = $return.'<option value="'.$row->id.'">'.$row->$submenu.'</option>';
}
$return = $return.'</select>';
return $return;
}


}

if function is used out of the class and used in index.php directly, returns expected value of it (there is no doubts - works ok)

I have a basic pagination class, I have used on several pages of a site I am working on. It works fine on 3 of the pages, but when I try to use it on any other pages, or even a new blank page I wrote, it does not work.

class Pagination {

    public $current_page;
    public $per_page;
    public $total_count;

    public function  __construct($page=1, $per_page=20, $total_count=0) {
        $this->current_page = (int)$page;
        $this->per_page = (int)$per_page;
        $this->total_count = (int)$total_count;
    }

    public function offset(){
        return ($this->current_page - 1) * $this->per_page;
    }

    public function total_pages(){
        return ceil($this->total_count/$this->per_page);
    }

    public function previous_page(){
        return $this->current_page - 1;
    }

    public function next_page(){
        return $this->current_page + 1;
    }

    public function has_prev_page(){
        return $this->previous_page() >= 1 ? true : false;
    }

    public function has_next_page(){
        return $this->next_page() <= $this->total_pages() ? true : false;
    }
That is the pagination class, and this is the code I use to call it, along with some debugging information I am using.
      
        if(isset($_GET['order'])){ $order = $_GET['order']; } else { $order = "id"; }
        if(isset($_GET['orderby'])){ $order_by = $_GET['orderby']; } else { $order_by = "ASC"; }      
            $page = !empty($_GET['page']) ? (int)$_GET['page'] : 1;
            $per_page = 2;
            $sql = mysql_query("SELECT * FROM orders WHERE customerid = 4");
            $result = mysql_fetch_array($sql);
            $total_count = mysql_num_rows($sql);
            //$total_count = Order::count_by_cust(4);
            $pagination = new Pagination($page, $per_page, $total_count);
            $sql = "SELECT * FROM orders WHERE customerid = 4 ORDER BY {$order} {$order_by} ";
            $sql .= "LIMIT {$per_page} ";
            $sql .= "OFFSET {$pagination->offset()}";  
            $orders = Order::find_by_sql($sql); 
            echo "Page:" . $page . "<br />PerPage:" . $per_page . "<br />Total:" . $total_count . "<br />Total Pages:" . $pagination->total_pages();

The customer ID is dynamic, but for debugging sake I am using the customer ID of 4. The output of the page has the following informaton:
Page:1
PerPage:2
Total:15
Total Pages:8

Has Prev Page:
Total Pages:8
Has Next Page:1

So i know all the variables are right, the problem is, it only prints a bold "1". Thats all, no numbers, or Next Page option.
However i use the EXACT same code in another couple pages, and it works fine, but with this current page and a few others. It does not work.

I have also tryed extracting just this information into a blank file to just get the page numbers, taking out all the pages other code, and it still only gives me "1".

Any ideas?

I have an issue that with some testing on an Access  class with a method getControlAccess it should only return true or false but as soon as I place a string of any sort
into the return my tests always returns true. Any help to point out if it is the way I am testing or the way I have written the method would be great. In the example
below it would return true.


In one class I have this method
Code: [Select]
class Access{
public function getControlAccess(){

return   'I am stuffed';
}
}

In the second class I have this
Code: [Select]
class AccessTests extends Access{
public function controlAccessTest(){
$return = "<ul>";
 
if ($this->getControlAccess() == TRUE){

$return .= "<li>getControlAcess should be true and is returning:<b> ". $this->getControlAccess() ."</b></li>";

} elseif ($this->getControlAccess() == FALSE){

$return .= "<li>getControlAcess should be false and is returning:<b> ". $this->getControlAccess() ."<b></li>";
} else {

$return .= "<li>getControlAcess is really stuffed:<b>". $this->getControlAccess() ."<b></li>";
}

$return .= "</ul>";
return $return;
}

public function setAccessTest($set){
return $set;
}

}

I am doing some practice with classes. MY class below echoes out input and radio fields based on the instantiation of the Form class (the code below is working!), but I am trying to resolve how to get my form radio fields so they are not in between every other form field as they are supposed to be next to eachother. If you run the below, you will see what I mean. And also is my approach at all sensible? I am only doing this for learning experience, so any advice please.

<?php
  class Form
  {
      private $fields = array();
      private $radios = array();
      private $actionValue;
      private $submit = "Submit Form";
      private $Nradios = 0;
      private $Nfields = 0;
      function __construct($actionValue, $submit)
      {
          $this->actionValue = $actionValue;
          $this->submit = $submit;
      }
      function displayForm()
      {
          echo "<form action='{$this->actionValue}' method='post'>\n\n";
          for ($j = 1, $i = 1; $j <= sizeof($this->fields), $i <= sizeof($this->radios); $j++, $i++) {
              echo "<p>\n<label>{$this->fields[$j-1]['label']} : </label>\n";
              echo "<input type='text' name='{$this->fields[$j-1]['name']}'>\n</p>\n\n";
              echo "<p>\n<label>{$this->radios[$i-1]['rlabel']} : </label>\n";
              echo "\n<input type='radio' name='{$this->radios[$i-1]['rname']}' value='{$this->radios[$i-1]['rvalue']}'>\n</p>\n\n";
          }
          echo "\n\n<input type='submit' value='{$this->submit}'>\n</form>";
      }
      function addField($name, $label)
      {
          $this->fields[$this->Nfields]['name'] = $name;
          $this->fields[$this->Nfields]['label'] = $label;
          $this->Nfields = $this->Nfields + 1;
      }
      function addRadio($rname, $rvalue, $rlabel)
      {
          $this->radios[$this->Nradios]['rname'] = $rname;
          $this->radios[$this->Nradios]['rvalue'] = $rvalue;
          $this->radios[$this->Nradios]['rlabel'] = $rlabel;
          $this->Nradios = $this->Nradios + 1;
      }
  }
?>

<?php
  $contact_form = new Form("process.php", "Submit Data >>");
  $contact_form->addField("first_name", "First Name");
  $contact_form->addField("last_name", "Last Name");
  $contact_form->addRadio("gender", "male", "Male");
  $contact_form->addRadio("gender", "femail", "Female");
  $contact_form->displayForm();
?>

Hi

Still very new to PHP but getting some good use out of it with includes.

I'm currently using this code to check the file name of the page and then give the corresponding anchor tag a class of active in order to style my main menu.

This is all working for most of my pages but my problem is that I now have multiple files called index.php one in the root of my site and some are in folders.

Is there any way around this issue? Can PHP check to see if its the index file in the root of the site or is there a better way. I suppose I could create a second variable in the index file in my root ie my home page and then check to say if the current page is called index and has the variable of home but how would I write this?

My code

Code: [Select]
$currentPage = basename($_SERVER['SCRIPT_NAME'], '.php');

<li><a href="/" <?php if ($currentPage == 'index') {echo 'class="active"';} ?>>Home</a></li>

I have mysqli object in Database class base:

class Database {
  private $dbLink = null;
  
  public function __construct() {
    if (is_null($this->dbLink)) {
      // load db information  to connect
      $init_array = parse_ini_file("../init.ini.inc", true);
      $this->dbLink = new mysqli($init_array['database']['host'],
                           $init_array['database']['usr'],
                           $init_array['database']['pwd'],
                           $init_array['database']['db']);
  
      if (mysqli_connect_errno()) {
        $this->dbLink = null;
      }
    }
  }

  public function __destruct() {
    $this->dbLink->close();
  }
}


Class derived is Articles where I use object dBLink in base (or parent) class and I can't access to mysqli methods (dbLink member of base class):

Articles class:

require_once ('./includes/db.inc');

  public function getArticlesByPosition($numArticles) {

      $i = 0;
      while ($ret = $result->fetch_array(MYSQLI_ASSOC)) {
        $arts[$i] = $ret;
      }
      $result->close();
      return $arts;
    }
  }
}


In my front page php I use article class:


include_once('./includes/articles.inc');
$articlesObj = new articles();
$articles = $articlesObj->getArticlesByPosition(1);
var_dump($articles);


[color=]Error that go out is follow[/color]

Notice: Undefined property: Articles::$dbLink in articles.inc  on line 89

Fatal error: Call to a member function query() on a non-object in articles.inc on line 89

If I remove constructor on derived class Articles result don't change

I have an existing instance of my class Database, now I want to call that instance in my Session class, how would I go about doing this?

Hi

Can you call Class A's methods or properties from Class B's methods?

Thanks.

Ok. I know you can pass the object of a class as an argument. Example:


class A {
    function test() {
        echo "This is TEST from class A";
    }
}


class B {
    function __construct( $obj ) {
        $this->a = $obj;
    }

    function test() {
       $this->a->test();
    }

}


Then you could do:

$a = new A();
$b = new B($a);


Ok so that's one way i know of.

I also thought that you could make a method static, and do this: (assuming class A's test is 'static')

class B {
    function test() {
       A::test(); 
   }
}


But that is not working.


I'd like to know all possible ways of accomplishing this. Any hints are appreciated. thanks

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?

help please how can I solve this error?

I'm trying to show my friend my website and it's not letting him or me view it.

I am using my own IP-address. (dashed out for security, but it is correct)
http://--.---.--.---/index-1.php
When he and I type this into our browser, we can an error called "Resource Not Found".

But, when I use localhost address, it works fine.
http://localhost/index-1.php

Does anyone know what is wrong?
Do I need to open a specific port?
