PHP - Do Exceptions Span All Functions And Methods?

Hi guys. I have a record shop online.

The following URL example shows the product info page without a problem:

http://www.mysite.com/tp/html/product/33/record1.html

Im using an .htaccess file as follows:

RewriteEngine On
RewriteRule ^product/([0-9]+)/(.*).html$ detail.php?id=$1 [L]

My problem is that the sound files are in a different folder on the server :

www.mysite.com/sf/soundfile.mp3

The mp3 sound files are not found or shown on the detail.page as they are in a different folder which doesnt have a rule associated with it. It doesnt need one as the mp3 file doesnt need SEO referencing.

How do i tell the .htaccess file to look in the sf  folder to find the mp3 files on my detail.php page?

thanks!

Well the title may seem a bit confusing, but heres an example:

Code: [Select]
<?php
class User{
   public $uid;
   public $username;
   protected $password;
   protected $email;
   public $usergroup;
   public $profile;
   

  public function __construct($id){
      // constructor code inside
  }

  public function getemail(){
      return $this->email;
  } 
   
  public function getusergroup(){
      return $this->usergroup;
  }

  public function getprofile(){
      $this->profile = new UserProfile($this->uid);
  }
}

class UserProfile(){
   protected $avatar;
   protected $bio;
   protected $gender;
   protected $favcolor;
   

  public function __construct($id){
      // constructor code inside
  }

  public function formatavatar(){
      // avatar formatting code inside
  }

  public function formatusername(){
      // format username?
  } 
}
?>

As you can see, the User class(an outer class) has a property called Profile, which can be instantiated as a UserProfile object(an inner class). The two objects have distinct functionalities, but there are times when the UserProfile object needs to access property and methods from the user object. I know its easy for outer class to access methods from inner class by using the single arrow access operator twice, but how about the other way around?

Lets say from the above example the userprofile can format the username displayed to the screen by adding a sun to the left of the username if the usergroup is admin, a moon if the usergroup is mod, and nothing if its just a member. The usergroup property is stored in the outer class, and can be accessed with this $user->getusergroup() method only. I know I can always do the hard way by passing a user object to the method's argument, but is there an easier way for the inner class UserProfile to access properties/methods for outerclass User? If so, how can I achieve that?

I recently had a need to check several arrays, and if an index wasn't set, set a variable to a given value.  The code was such that I couldn't perform the isset check all at once.  I then thought "wouldn't it be great if I could try the script, and catch the error or warning". Searching a bit, I came across the following script.  I am a little nervous, however, that there might be negative consequences of doing so.  Thoughts?

set_error_handler(function($errno, $errstr, $errfile, $errline, array $errcontext) {
// error was suppressed with the @-operator
if (0 === error_reporting()) {
return false;
}

throw new ErrorException($errstr, 0, $errno, $errfile, $errline);
});

try {
dns_get_record();
} catch (ErrorException $e) {
// ...
}

Hello

It's about exception handling...

I have two if statements, one inside the other. And I want to throw an exception from each, if one of them is FALSE. What "technique" should I use? I think throwing same exception with the same message within two if's is a bit messy.

like:
if $x is true
  //go to 2nd if:
  if $y is true
     return value
  if $y is false: throw exception "Invalid number"
if $x is false: throw exception "Invalid number"

Thanks,

Hi,

I am a php newbie, who has a page that relies on some php scripts, and to which I am trying to add a login page written in php.  I took the example from he

http://www.howtodothings.com/computers-internet/how-to-make-a-login-system-for-your-website

Basically it consists of adding:

<?
require("log.php");
?>

to the top of any page I want to protect, a log.php file which performs the actions of the form, linking to a mySQL database, and a login.php file which contains the form.

I have the login working fine, but it breaks one of the PHP scripts on the page that is protected.  It is an upload script, called Weaverbox, based on FancyUpload.  The uploads which are handled by a file called upload.php, aren't happening.  The progress shows that they are being uploaded, but nothing is uploaded, and there is no success message.  As soon as I remove the code from the top of the page requiring log.php all works fine again.

I think I may have to add some rules/extensions to resolve this conflict, but I don't know how to go about this.  Would someone be able to help me get it sorted?

Thanks

Nick

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:

I don't know if this belongs here; sorry if it doesn't.

I'm using a method=get on a form as I need to pass information through a URL once the form has been submitted.
But I also need to INSERT some data from that form to multiple tables.

- How can I stop the GET from passing my other variables into the URL?
- How do I make the form submit to itself? I need to use the 'index.php?p=checkout' as this matches with a switch statement, which matches to the checkout page. The function PHP_SELF will just refresh to the index.php page, which will not have any of this checkout's page validation.

Here's my code:
Code: [Select]
<h2>Please enter your details</h2>
<h3>All fields required</h3>
<div id="checkout">

<?php

if (isset($_GET['checkout'])){
require_once ('./includes/connectvars.php');

$service = $_GET['cardAuth'];

what are magic methods? when do we need to use magic methods? what are the advantages of using magic methods? thanks in advanced.

hey guys im wdondering if there's a magic method which works like  

__GET()

    but allows you to put a parameter in...thank you

<?php

class test
{
      public function run()
      {
              $this->object->('string');
              // __get with parameter?
       }

       public function __get($value)
       {
              return $this->{$value}
       }
}

?>

I have a class that has the __get and __set magic methods defined.  The idea is to use those to communicate with the __get and __set methods in a database table object which is a protected attribute of this class.  Then I can quickly build out models without having to bother with method definitions aside from those that need modifications made to the data before saving.

The problem is, they don't seem to be doing anything.  I get an undefined function error the first time I call getVarx().   I don't actually have any of the attributes I'm trying to get and set defined in the object, but I thought that was the point of these magic methods.  Am I missing something here?

Thanks,
Brandon

So, I'm starting a new project and thought I would try a new approach at loading files and classes to process output.  I think my logic is correct, but for some reason I'm getting a blank page.  Basically instead of having seperate pages to output different functions and such, I store everything in one page.  It's the same deal as the switch case approach, but it uses a foreach loop to cycle through the actions, classes, and functions which are stored in an array.

Here's my index.php file:
Code: [Select]
<?php

require('config.php');
include('languages/english.php');
include('classes/Template.php');

$template = new Template;

$viewPages = array( 
'category' => array('classfile' => 'Category.php', 'classname' => 'category', 'functions' => array('create', 'delete', 'modify', 'merge')),
'questions' => array('classfile' => 'Question.php', 'classname' => 'Question', 'functions' => array('create', 'delete', 'modify', 'votegood', 'votebad'))
);


$currentPage = $_REQUEST['action'];

foreach($viewPages as $action => $settings){

if($currentPage == $action){
require(INCLUDE_ROOT.'/classes/'.$settings['classfile']);

$class = new $settings['classname'];
$function = $_REQUEST['do'];
$class->$function();

$template->loadTemplate($settings['classname']->viewFile, $vars = array());
if($template->message == FALSE){
die($template->message);
}

}

}

?>
Here's the Template class file:
Code: [Select]
<?php

class Template {

var $file;
var $vars;
var $message;

function loadTemplate($file, $vars){

if(empty($file) || empty($vars)){
$this->message = LANG_ERR_7;
} else if($file = file_get_contents(INCLUDE_ROOT.'/'.$file)){
$this->message = LANG_ERR_7;
} else {
foreach($vars as $key => $val)
$file = str_replace('{'.$key.'}', $val, $file);
}

$this->message = FALSE;
return $file;

}

}

?>
I tried visiting the category action(index.php?action=category;do=create).  This is the classfile for that
Code: [Select]
<?php

class category {

var $id;
var $title;
var $description;
var $uri;
var $message = array();

if($_POST['submit']){

//Review the user input and make ure everything is ok
$messages = array();
if($this->title == FALSE){
$messages['title'] = LANG_ERR_1;
} else if(strlen($this->title) > 30 || strlen($this->title < 5)){
$messages['title'] = LANG_ERR_2;
} else if($this->description == FALSE){
$messages['description'] = LANG_ERR_3;
} else if(strlen($this->description) > 400 || strlen($this->description) < 10){
$messages['description'] = LANG_ERR_4;
} else {
$messages = FALSE;
}

if($messages != FALSE){
$this->messages = $messages;
$this->viewFile = INCLUDE_ROOT.'/template/index_body.tpl';
} else {
$this->title = htmlentities($this->title);
$this->title = stripslashes($this->title);
$this->title = htmlspecialchars($this->title);

$this->description = htmlentities($this->description);
$this->description = htmlspecialchars($this->description);
$this->description = nl2br($this->description);

$query = "

VALUES('".$this->title."', '".$this->desscription."')";

if(mysql_query($query)){
$this->message['succes'] = LANG_ERR_5;
} else {
$this->message['fail'] = LANG_ERR_6;
}

$this->viewFile = INCLUDE_ROOT.'/template/message_body.tpl';

}

} else {

$this->viewFile = INCLUDE_ROOT.'/template/create_category.tpl';

}

}

}

?>
Now if you look at the Category class, the template file it sets is the "category_create.tpl" file, which I haven't created yet.  I'm expecting there to be an error associated with the template class and the file_get_contents function that calls the file, but like I said, I'm just getting a blank page.

I've never tried this approach before, so I have no idea what's causing this.  Any help would be greatly appreciated.

Hi, I'm new to php and am attempting to build a site where the navigation and content is built with query functions. 
My current tables in my database are Categories, Products, and Variation.  So a person chooses a category -> then a product -> then a product page shows variations for that product. The problem I am currently having is after when a person selects a section the previous section selected is reset.  So lets a person selects a category the product list is shown, but when a person selects a product, the category is no longer selected in the navigation.  Or if someone selects product and sees all the variations, if he selects a variation the product ID is reset.  I've tried to comb through the internet for some type of solution.  I came across concatenating URL encode, but am not sure if this is the correct solution.  I tried concatenating one of my urls
with Code: [Select]
"<a href=\"product_detail.php?cat=" . urlencode($sel_cat["id"]) . '&' . "product=" . urlencode($sel_product['id']) . '&' . "var=" . urlencode($var["id"]) . "\"
its a bit of a stab in the dark. 

My $_GET function is
Code: [Select]
function find_selected_product() {
global $sel_cat;
global $sel_product;
global $sel_var;
if (isset($_GET['cat'])) {
$sel_cat = get_cat_by_id($_GET['cat']);
} elseif (isset($_GET['product'])) {
$sel_cat = NULL;
$sel_product = get_product_by_id($_GET['product']);
} elseif (isset($_GET['product'])) {
$sel_product = get_product_by_id($_GET['product']);
$sel_var = get_default_var($sel_product['id']);
} elseif (isset($_GET['var'])) {
$sel_product = NULL; //test
$sel_var = get_variation_by_id($_GET['var']);
} else {
$sel_cat = NULL;
$sel_product = NULL;
$sel_var = NULL;

}
}
My navigation code is
Code: [Select]
function public_navigation($sel_cat, $public = true) {
$output = "<td class=\"c1\"><div class=\"sidenav\"><ul>";
$cat_set = get_all_cats($public);
while ($cat = mysql_fetch_array($cat_set)) {
$output .= "<li>";
if ($cat["id"] == $sel_cat['id']) { $output .= "<a class=\"current\""; }
$output .= "<a href=\"index.php?cat=" . urlencode($cat["id"]) . "\">{$cat["cat_name"]}</a></li>";

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

return $output;
}
My product is divided into gender and is written like

Code: [Select]
function cat_content_ladies($sel_cat, $sel_product, $female = true)
{
$output = "<ul class=\"regions\">";
$cat_set = get_all_cats($female);
while ($cat = mysql_fetch_array($cat_set))
{ if ($cat["id"] == $sel_cat['id'])
{
$product_set = get_products_for_female($cat["id"], $female);
$output .= "<tr>";
while ($product = mysql_fetch_array($product_set))
{
if ($cat["id"] == $sel_cat['id'])
{
$output .= "<tr>";
$output .= "<div class=\"pre\"><a href=\"product_detail.php?product=" . urlencode($product["id"]) . "\"></li>";
$output .= "<img src=\"{$product["img_src"]}\" height=\"121\" width=\"121\">";
$output .= "<div>{$product["prod_name"]}</a></div>";
}
}
$output .= "</tr>";
}
}
return $output;
}
My variation table is set up in thumb nails and is written in this function
Code: [Select]
function show_thumb($sel_product, $sel_var, $public = true)
{
$output = "<ul class=\"subjects\">";
$product_set = get_all_products($public);
while ($product = mysql_fetch_array($product_set)) {
$output .= "<li";
if ($product["id"] == $sel_product['id']) { $output .= " class=\"selected\""; }
//$output .= "><a href=\"product_detail.php?product=" . urlencode($product["id"]) .
//"\">{$product["id"]}</a></li>";
if ($product["id"] == $sel_product['id']) {
$var_set = get_variations_for_product($product["id"], $public);
$output .= "<ul class=\"pages\">";
while ($var = mysql_fetch_array($var_set)) {
$output .= "<li";
if ($var["id"] == $sel_var['id']) { $output .= " class=\"selected\""; }
$output .= "><a href=\"product_detail.php?var=" . urlencode($var["id"]) .
"\">{$var["id"]}</a></li>";

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

 


any light on this subject would be greatly appreciated.

Hi, I am trying to get my head around classes, interfaces and methods for different animals

 

this is what I have so far:

<?php 
interface animal {
  function walk();
  function fly();
  function swim();
}
class monkey implements animal{
  const interface1 = "I am from test class";

  function noise() {
    echo "ooh ooh ah ah!";
  } 

  function walk() { 
    echo "monkey is walking";
  }
  function fly() { 
    echo "monkey is Flying";
  }
  function swim() { 
    echo "monkey is Swimming";
  }
  public function display() {
    echo monkey::interface1;
    echo PHP_EOL;
  }

}

class bear implements animal{
  const interface1 = "I am from test class";

  function noise() {
    echo "Grrr!";
  } 

  function walk() { 
    echo "Bear is walking";
  }
  function fly() { 
    echo "Bear is Flying";
  }
  function swim() { 
    echo "Bear is Swimming";
  }
  public function display() {
    echo bear::interface1;
    echo PHP_EOL;
  }

}
$Obj = new monkey();
$Obj->display();
$Obj1 = new bear();
$Obj1->display();
?>

I'm a bit stumped as  animal interface not calling all functions?! please help

hello,

i have been following the php.net oop manual but im having a little trouble understanding something.

on this page in the manual: http://uk3.php.net/manual/en/language.oop5.basic.php
it shows this code and if i seperate it out i cant get it to echo the results i want. what am i doing wrong?
i have added a little extra code .

class Bear
Code: [Select]
class Bear {
    // define properties
    public $name;
    public $weight;
    public $age;
    public $sex;
    public $colour;

    // constructor
    public function __construct() {
       
                $this->name = "winny the poo";
$this->weight = 100;
$this->age = 0;
$this->sex = "male";
$this->colour = "brown";
    }

    // define methods

    public function eat($units) {
        echo $this->name." is eating ".$units." units of food... <br/>";
        $this->weight += $units;
    }

    public function run() {
        echo $this->name." is running... <br/>";
    }

    public function kill() {
        echo $this->name." is killing prey... <br/>";
    }

    public function sleep() {
        echo $this->name." is sleeping... <br/>";
    }


}

class PolarBear
Code: [Select]
class PolarBear extends Bear {

    // constructor
    public function __construct() {
        parent::__construct();
        $this->colour = "white";
        $this->weight = 600;
    }

function polarbar()
    {
        // Note: the next line will issue a warning if E_STRICT is enabled.
        Bear::bear();
    }

    // define methods
    public function swim() {
        echo $this->name." is swimming... ";
    }
}


now if i try to get back the results i have trouble.

this is fine
Code: [Select]
$bear = new Bear();

$bear->eat($units);
$bear->eat();
$bear->run();
$bear->kill();
$bear->sleep();

that echos back
Quote

//THE BEAR
winny the poo is eating 5 units of food...
winny the poo is eating units of food...
winny the poo is running...
winny the poo is killing prey...
winny the poo is sleeping...

//THE POLAR BEAR
winny the poo is eating 5 units of food...
winny the poo is eating units of food...
winny the poo is running...
winny the poo is killing prey...
winny the poo is sleeping...
winny the poo is swimming...



THAT FINE but how come i can echo out each of the properties?
why do these ways not work?

Code: [Select]
Bear::eat($units);
Bear::eat();
Bear::run();
Bear::kill();
Bear::sleep();

or

Code: [Select]
$bear = new Bear();
$bear->$name;
$bear->$weight;
$bear->$age;
$bear->$sex;
$bear->$colour;

or

Code: [Select]
echo Bear::eat($units);
echo Bear::eat();
echo Bear::run();
echo Bear::kill();
echo Bear::sleep();

or

Code: [Select]
$bear = new Bear();
echo $bear->$name;
echo $bear->$weight;
echo $bear->$age;
echo $bear->$sex;
echo $bear->$colour;

and the same goes for PolarBear

if i try and get back any of the properties on a page i get nothing ???

i even tried putting it in a loop and that didnt work
Code: [Select]
$bear = new Bear();

foreach ($bear as $bears){
echo $bears->$name;
echo $bears->$weight;
echo $bears->$age;
echo $bears->$sex;
echo $bears->$colour;
}

whats wrong.
why cant i get any results from these ?
thanks
