PHP - New Class From Return Value Of A Method

Any thoughts as to why I'm getting an error for this line of code?

Code: [Select]
if (isset($this->input->post('bcc[]')))
Error reads: Fatal error: Can't use method return value in write context

If someone knows can they explain it to me so I understand it please.

Hi people!

class FirstOne{

public function FunctionOne($FirstInput){
//do stuff and output value
return $value1;
}

}


Then:-


class SecondOne{

public function FunctionTwo($AnotherInput){
//do stuff and output value
return $value2;
}

}


What I want to know is this, if I want to use FunctionOne() in Class SecondOne do I do it like this:-

(Assume as I have instantiated the first class using $Test = new FirstOne(); )


class SecondOne{

function SecondedFunction(){
global $Test;
return $Test->FunctionOne();
}

public function FunctionTwo($AnotherInput){
//do stuff and output value
return $value2;
}

public function FunctionThree(){

//some code here
$this->Test->SecondedFunction();<--I think as I can omit the $this-> reference
}
}


My point is: Do I have to do it this way or is there way of having this done through __construct() that would negate the need for a third party function?

I have a version working, I just think that it is a little convoluted in the way as I have done it, so I thought I would ask you guys.

Any help/advice is appreciated.

Cheers

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?

I am trying to do the following. Except I know that 'return' is not the right method to use, as it stops the script, so what ends up happening is only one row is returned, instead of the three that are there. With return, the data is being passed without being immediately printed, and I end up with the data (but not all of it, because the script stops) in correct place in the page.

If I replace return () with echo(), it works fine, in terms of returning the correct data.

However, with the way things are setup, if I use echo, the results print at the head of my page. I am using function CreateSideMenu to establish the values for content, and then another function, later on the index.php page, actually creates the page. So what I need is to have something, similar to return (), that passes the information on, but does not immediately print it.

Do I make sense?

see code below:


function CreateSideMenu ()

{ // open CreateSideMenu function

include ('/Users/max/Sites/rdbase-llc/hidden/defin/kinnect01.php');

$query = "SELECT content_element_title, content_element_short_text FROM content_main";

$result = mysql_query ($query, $dbc);

while ($row = mysql_fetch_array ($result, MYSQL_ASSOC))

{

return ("<p>" . $row[content_element_title] . "</h2>\n<p>" . $row[content_element_short_text] .  "</p>");

}


Thanks ahead of time.

I've done pretty much everything I can come up with.
The method itself works fine, if I print_r(); just before returning it, it successfully returns the array.
But once returned, it's empty.
Heres my code:

Any ideas?

I have a class ServerBridge which is used to proxy browser ajax requests received by a web server to another API server.  To update a record (or create a record is similar):

Browser client makes PUT request to web server. Web server modifies the uri path and passes the body plus headers connection, accept, accept-encoding, accept-language, content-type, content-length only to the API server. The API server does work and returns the location of the resource on itself to the web server. The web server modifies the location header to point to the resource location on itself, and returns all received headers except Date, Server, X-Powered-By, Access-Control-Allow-Origin, Access-Control-Allow-Methods, Access-Control-Allow-Headers to the browser client. Browser client makes another undesired PUT request to web server.

Why is step 5 occurring and how do I prevent it?  I don't really mind the browser client making another request to the resource, but it would need to be GET and not PUT.  Also, is my white-list headers to forward to api server and black-list headers to return to browser client appropriate?

I haven't posted the ServerBridge script (but can if needed), but did include the requests and headers related to the browser client, web server, and api server below.

Browser client JavaScript

$('.edit-record').simpleEdit('/api/accounts');

jQuery.fn.extend({
    simpleEdit: function(url, options) {
        var dOptions={type: 'text', ajaxOptions: {type: "PUT"}, placement: 'right', send: 'always' };
        options=options?options:{};
        return this.each(function() {
            var $t=$(this);
            var o=Object.assign({
                url: url+'/'+$t.closest('tr').data('id'),
                title: 'Enter '+$t.data('name')
            }, dOptions, options);
            $t.editable(o);
        });
    }
});

            }
            return $headers;
        }
    );

I found class on the net, and i am having a bit of a problem to understand how does update method works. Here is the code:
Code: [Select]
public function update() {
  global $database;
// Don't forget your SQL syntax and good habits:
// - UPDATE table SET key='value', key='value' WHERE condition
// - single-quotes around all values
// - escape all values to prevent SQL injection
$attributes = $this->sanitized_attributes();
$attribute_pairs = array();
foreach($attributes as $key => $value) {
  $attribute_pairs[] = "{$key}='{$value}'";
}
$sql = "UPDATE ".self::$table_name." SET ";
$sql .= join(", ", $attribute_pairs);
$sql .= " WHERE id=". $database->escape_value($this->id);
  $database->query($sql);
  return ($database->affected_rows() == 1) ? true : false;
}

I have form like this to deal with update:
Code: [Select]
<form action="index.php?page=languages" enctype="multipart/form-data" method="POST">
    <?php foreach($language as $lang){ ?>
    <input type="hidden" name="MAX_FILE_SIZE" value="<?php echo $max_file_size; ?>" />
    <label>Jezik</label><input type="text" size="50" name="language" value="<?php  echo $lang->lang; ?>" /><br>
    <input type="hidden" name="id_lang" value="<?php echo $lang->id_lang; ?>"  />
<label>Slika</label><input type="file" name="image"><?php 
echo "<img src=\"../images/";
echo $lang->image;
echo "\">";
?> <br>
    <label>Pozicija</label><input type="text" name="pozicija" value="<?php echo $lang->pozicija; ?>" size="2" /></p> <br>
<input type="submit" name="submit_update" value="Unesi">
    <?php } ?> 
    </form>
and code to start the function:
Code: [Select]
if(isset($_POST['submit_update'])) {
$language = new Jezik();
$language->update();
}
What next???

Script:

<?php

class Article{
    public function fetch_all(){
        global $pdo;

        $query = $pdo->prepare("SELECT * FROM `articles` ORDER BY `article_timestamp` DESC");
        $query->execute();

        return $query->fetchAll();
    }

    public function fetch_data($article_id){
        global $pdo;

        $query = $pdo->prepare("SELECT * FROM `articles` WHERE `article_id` = ?");
        $query->bindValue(1, $article_id);
        $query->execute();

        return $query->fetch();
    }

    /*
     * These have gotten added later on.
     */
    
    public function delete($id){
        global $pdo;

        $query = $pdo->prepare("DELETE FROM `articles` WHERE `article_id` = ?");
        $query->bindValue(1, $id);
        $query->execute();

        // The "return" here.

    }

    public function edit_page($title, $content, $aticle_id){
        global $pdo;

        $query = $pdo->prepare("UPDATE `articles` SET `article_title` = ?, `article_content` = ? WHERE `article_id` = ?");

        $query->bindValue(1, $title);
        $query->bindValue(2, $content);
        $query->bindValue(3, $article_id);

        $query->execute();

        // The "return" here.
    }

}


?>

I have this from a tutorial. In the function "fetch_all()" it uses "fetchAll()" at the spot where the "return" is, and in the function "fetch_data()" it uses "fetch()" at the spot where the "return" is.   My Question: What may have to use for the function "delete()" and the function "edit_page()" at the spot where "return" would be?

Hey,

I've not used PHP for a while and never really used classes!

I was reading some code today and I saw a statement something like:

Code: [Select]
$s = &MyClass::("Something");
From reading the PHP Manual it has an example which looks like this for 5.3, however my server still uses 5.2 (.9), how do I do similar using that?

Preferably something along these lines...

Code: [Select]
class spook{
function __construct($n){
if($n==1){
return "hello";
} else {
return "goodbye";
}
}
}
$a=spook::();
print $a;
Cheers!

i.e. What was the old method before the Scope resolution operator?

Using this locally works fine:


$html = $name::add_content($name, $html);


but i get the double colon error whe using it live.
$name is a name of a valid class.

What could throw this error when it works locally?

Well in the class UserValidator I have a public method validate(), which checks the validation type and then calls specific private methods to execute the validation script. It gets a bit tricky here since the method validate() has to decide what private method to call. I am thinking about using call_user_func_array(), the script currently looks like this below:

Code: [Select]
public function validate(){
      // The core method validate, it sends requests to different private methods based on the type
      if(empty($this->type)) throw new Exception('The validation type is empty, something must be seriously wrong...');
      if(is_array($this->type) and !is_array($this->value)) throw new Exception('Cannot have scalar value if the type is an array.');
      if(!is_array($this->type) and is_array($this->value)) throw new Exception('Cannot have scalar type if the value is an array.');
     
      // Now we are validating our user data or input!
      $validarray = array("register", "login", "password", "session", "email", "reset", "profile", "contacts", "friends");
      foreach($this->type as $val){
         $method = "{$val}validate";
         if(in_array($val, $validarray)) call_user_func_array(array($this, $method), array());
      }     
  }

The method to execute depends on the validation type passed into the validator class, so it is somewhat like a dynamic function call. The problem is, well, I am not sure if I am using call_user_func_array() properly. I read it from php manual that it needs to accept a class instance, but there is no such instance inside a class method so I use $this in the argument. Is this the correct way of using call_user_func_array()? If not, how am I supposed to do this? thanks.

Hi

I have created a Database class that uses the singleton method.

I have a query method within this class so i would call this to return an array of results.

What i need to know is what would be the best way to use this returned array

Database Class:
Code: [Select]
<?php

class Database
{
private static $dbInstance;
private $hostname;
private $username;
private $password;
private $database;

private function __construct()
{
$this->hostname = 'localhost';
$this->username = 'user';
$this->password = 'pass';
$this->database = 'test';

mysql_connect($this->hostname, $this->username, $this->password);
mysql_select_db($this->database);
}

public static function getDBInstance()
{
if (!self::$dbInstance) 
     { 
         self::$dbInstance = new Database(); 
      } 

      return self::$dbInstance; 
}


public function query($q)
{
return mysql_query($q);
}


}

?>

Person Class:
Code: [Select]
<?php
require_once('Database.php');

class person
{
public function getName($id)
{
$con = Database::getDBInstance();
$query = $con->query("select name from data where id = ".$id);
$result = mysql_fetch_assoc($query);
echo $result['name'];

}


}

?>

Index page:
Code: [Select]
<?php

require_once('person.php');

?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<?php

$person = new person();
$person->getName(1);
echo "<br />";
$person->getName(2);


?>

</body>

Hey guys,

So im building a Content Management System for my A2 project in Computing, and i have a dataBase class. Now, i can return one thing, or do things like inserts however im having a problem returning a list of things such as:

dataBase.class.php

Code: [Select]

          public static function getNYCPost($table, $limit)
{
dataBase::_dbConnect();
if($limit == 0)
{
//debug: echo 'in as 0';
$data = mysql_query("SELECT id, linklabel FROM ".$table." WHERE showing='1' AND id >= 2");
}

if($limit == 1)
{
//debug: echo 'in';
$data = mysql_query("SELECT id, linklabel FROM ". $table ." WHERE showing='1' AND id >= 2 ORDER BY id DESC LIMIT 5");
return $data;
}
}

When i try to do this in the main code:

index.php

Code: [Select]
<?php
  $list = dataBase::getNYCPost($pages,1);
//  echo $list;
  while ($row = mysql_fetch_array($list)) 
{ 
 $pageId = $row["id"];
 $linklabel = $row["linklabel"];
 $menuDisplay .= '<a href="index.php?pid=' . $pid . '">' . $linklabel . '</a><br />';
}
echo $menuDisplay;
  ?>
$list doesnt return anything, the previous method i used in the class was to make a list and an array and put the contents of the query in an array like:

Code: [Select]
list($list[] = $row);
or something i cant quite remember i saw a youtube video tutorial and it worked for them, but it wasnt for me.


If anyone knows how i can return various rows from a database it would be appreciated

Thanks.

json_decode returns a stdClass Object.
Is there any way where I can get instance of my class instead of the same?

I mean If I json_decode the below string then it will provide me instance of stdClass and not instance of Person class
{"name":"a"}

How to achieve the same?

Thanks in advance
