  1. I am getting Fatal error: Uncaught Error: Call to a member function real_query() on null with this code: public final function Retrieve($TABLE, $CRIT){ $_query = "SELECT * FROM `{$TABLE}` WHERE "; foreach($CRIT as $_field => $info){ $_query .= " `{$_field}` = `{$info}` &&"; } if($this->LINK->real_query(rtrim($_query, ' &'))){ return $this->LINK->store_result(); } else{ return json_encode(array("Error"=>$this->LINK->errno(), "Description"=>$this->LINK->error())); } } (LINK is my mysql_connect() result.) I have tried everything i can think of, ->query, going to mysqli_query, breaking it sown and using a $result variable, but nothing seems to work...
  2. This is my first oop php library and wanted to get advice on how I can improve what I wrote. This is what I needed to do: I'm also not sure on what it meant by "proportionally resize the shape up or down, given a floating-point scale factor" I think what I did might be right but I could be wrong. Also am I supposed to have a new class for each shape or is there a better solution? Any help is much appreciated. <?PHP echo "Circle (r=5) <br/>"; $circle = new circle(5); $circle->getArea(); $circle->getPerimiter(); $circle->scale(up, .5); echo "Scaled up .5<br/>"; $circle->getArea(); $circle->getPerimiter(); echo "<br/>Right Triangle (a=4, b=5) <br/>"; $rt = new RightTriangle(4, 5); $rt->getArea(); $rt->getPerimiter(); $rt->scale(down, .5); echo "Scaled down .5<br/>"; $rt->getArea(); $rt->getPerimiter(); echo "<br/>Equilateral Triangle <br/>"; $et = new EquilateralTriangle(6); $et->getArea(); $et->getPerimiter(); $et->scale(up, .; echo "Scaled Up .8<br/>"; $et->getArea(); $et->getPerimiter(); echo "<br/>Rectangle<br/>"; $r = new Rectangle(8, 7); $r->getArea(); $r->getPerimiter(); $r->scale(down, .; echo "Scaled Down .8<br/>"; $r->getArea(); $r->getPerimiter(); echo "<br/>Square<br/>"; $s = new Square(25); $s->getArea(); $s->getPerimiter(); $s->scale(up, 2.5); echo "Scaled Up 2.5<br/>"; $s->getArea(); $s->getPerimiter(); echo "<br/>Parallelogram<br/>"; $p = new Parallelogram(5.7, 6.; $p->getArea(); $p->getPerimiter(); $p->scale(up, 1); echo "Scaled Up 1<br/>"; $p->getArea(); $p->getPerimiter(); class Circle { public function __construct( $radius ) { $this->radius = $radius; } public function getArea() { echo number_format(pow($this->radius, 2) * M_PI, 2)."<br/>"; } public function getPerimiter() { echo number_format(2 * M_PI * $this->radius, 2)."<br/>"; } public function scale($direction, $scale) { if($direction == 'up') { $this->radius = $this->radius + ($this->radius * $scale); } else { $this->radius = $this->radius - ($this->radius * $scale); } } } class RightTriangle { public function __construct( $a, $b ) { $this->a = $a; $this->b = $b; } public function getArea() { echo number_format(($this->a*$this->b/2), 2)."<br/>"; } public function getPerimiter() { echo number_format($this->a + $this->b + sqrt(pow($this->a, 2) + pow($this->b, 2)), 2)."<br/>"; } public function scale($direction, $scale) { if($direction == 'up') { $this->a = $this->a + ($this->a * $scale); $this->b = $this->b + ($this->b * $scale); } else { $this->a = $this->a - ($this->a * $scale); $this->b = $this->b + ($this->b * $scale); } } } class EquilateralTriangle { public function __construct( $a ) { $this->a = $a; } public function getArea() { echo number_format((sqrt(3)/4)*pow($this->a,2),2)."<br/>"; } public function getPerimiter() { echo number_format(3 * $this->a, 2)."<br/>"; } public function scale($direction, $scale) { if($direction == 'up') { $this->a = $this->a + ($this->a * $scale); } else { $this->a = $this->a - ($this->a * $scale); } } } class Rectangle { public function __construct( $w, $l ) { $this->w = $w; $this->l = $l; } public function getArea() { echo number_format($this->w * $this->l,2)."<br/>"; } public function getPerimiter() { echo number_format(2 * ($this->w + $this->l), 2)."<br/>"; } public function scale($direction, $scale) { if($direction == 'up') { $this->w = $this->w + ($this->w * $scale); $this->l = $this->l + ($this->l * $scale); } else { $this->w = $this->w - ($this->w * $scale); $this->l = $this->l - ($this->l * $scale); } } } class Square { public function __construct( $a ) { $this->a = $a; } public function getArea() { echo number_format(pow($this->a,2),2)."<br/>"; } public function getPerimiter() { echo number_format(4 * $this->a, 2)."<br/>"; } public function scale($direction, $scale) { if($direction == 'up') { $this->a = $this->a + ($this->a * $scale); } else { $this->a = $this->a - ($this->a * $scale); } } } class Parallelogram { public function __construct( $a, $b ) { $this->a = $a; $this->b = $b; $this->h = $a/$b; } public function getArea() { echo number_format($this->b * $this->h,2)."<br/>"; } public function getPerimiter() { echo number_format(2 * ($this->a + $this->b), 2)."<br/>"; } public function scale($direction, $scale) { if($direction == 'up') { $this->a = $this->a + ($this->a * $scale); $this->b = $this->b + ($this->b * $scale); } else { $this->a = $this->a - ($this->a * $scale); $this->b = $this->b - ($this->b * $scale); } } } ?>
  3. I was practicing OOP and made a simple class to log logins. Does anyone see any problems with this or improvements that can be made? Any issue with using NOW() in the query string instead of a placeholder? In another thread, @Jaques1 said: How would I implement that? I rtfm and don't understand it as of yet. <?php // ---------------------------------------------------------------------------- // Database Connection // ---------------------------------------------------------------------------- $dbhost = 'localhost'; $dbname = 'test'; $dbuser = 'root'; $dbpass = ''; $charset = 'utf8'; $dsn = "mysql:host=$dbhost;dbname=$dbname;charset=$charset"; $opt = [PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION, PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC, PDO::ATTR_EMULATE_PREPARES => false, ]; $pdo = new PDO($dsn, $dbuser, $dbpass, $opt); //------------------------------------------------------------------------ // //------------------------------------------------------------------------ $valid_login = new LogLoginStatus($pdo); $valid_login->validLogin('goodusername'); $invalid_login = new LogLoginStatus($pdo); $invalid_login->invalidLogin('bad_username', 'bad_password'); //------------------------------------------------------------------------ // //------------------------------------------------------------------------ class LogLoginStatus { /** * Log Valid/Invalid logins * * @param string login_username * @param string login_password */ public function __construct($pdo) { $this->pdo = $pdo; } function validLogin($username) { $sql = "INSERT INTO user_login (login_status, login_ip, login_username,login_password, login_datetime) values(?, INET_ATON(?), ?, ?, NOW())"; $stmt = $this->pdo->prepare($sql); $stmt->execute(array( 1, $_SERVER['REMOTE_ADDR'], $username, '***' )); } function invalidLogin($username, $password) { $sql = "INSERT INTO user_login (login_status, login_ip, login_username,login_password, login_datetime) values(?, INET_ATON(?), ?, ?, NOW())"; $stmt = $this->pdo->prepare($sql); $stmt->execute(array( 0, $_SERVER['REMOTE_ADDR'], $username, $password )); } } ?> CREATE TABLE `user_login` ( `login_id` int(11) NOT NULL AUTO_INCREMENT, `login_status` tinyint(1) DEFAULT NULL, `login_ip` int(10) unsigned DEFAULT NULL, `login_username` varchar(255) DEFAULT NULL, `login_password` varchar(255) DEFAULT NULL, `login_datetime` datetime DEFAULT NULL, PRIMARY KEY (`login_id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
  4. Please see attached my bank account class files. The key guidance I need is how to instantiate a class from another class. For example, you can see in Customer.class.php, I instantiate a new Account, but am not sure how i pass in the balance and account number to Customer in order that they can instantiate the Account? This is the same as Account instantiate a BankCard object. I am a little confused - any help appreciated. BankAccountApp.zip
  5. Hi All, I've been interested in writing a PHP pdo configuration file so that I can include connections in various files on my site. While I was looking up some possible solutions I stumbled across an interesting post on stack overflow http://stackoverflow.com/questions/11369360/how-to-properly-set-up-a-pdo-connection The first responder suggested the code below. However, I don't understand how to access the connection and make query calls. I'm confused by how it's possible to return a variable name as an object { return new $name( $this->connection ) }. Also, If someone could explain what the author means by { $something = $factory->create('Something');}. Wouldn't the "Something" need to be a class? And how would that class get the db connection? All the best, Karma $provider = function() { $instance = new PDO('mysql:......;charset=utf8', 'username', 'password'); $instance->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); $instance->setAttribute(PDO::ATTR_EMULATE_PREPARES, false); return $instance; }; class StructureFactory { protected $provider = null; protected $connection = null; public function __construct( callable $provider ) { $this->provider = $provider; } public function create( $name) { if ( $this->connection === null ) { $this->connection = call_user_func( $this->provider ); } return new $name( $this->connection ); } } $factory = new StructureFactory( $provider ); $something = $factory->create('Something'); $foobar = $factory->create('Foobar');
  6. Hi all, I have just put together a tentative proof of concept MVC framework proposal. After many weeks of slogging through an array of PHP MVC tutorials and courses (some of which I paid for) I have decided to strip back all the frills, bells and whistles to try and put together a core proof of concept that uses best practices. In this simplified example I am trying to test the viability of the framework itself... so there is no routing code or query string management and the controller and action are hard coded. Here is the repository: https://github.com/JethroHazelhurst/psr-4-mvc I like this framework because it: Has clear seperation of concerns Is not cluttered with static functions Is clearly namespaced - thanks to the PSR-4 autoloading Has a clear way of passing data to and from the model - e.g. $this->_view->foo = $this->_model->getBar(); Below is the directory structure: and here is a print_r of my Object structure: Questions I am interested in hearing any feedback on the idea... I can't see any glaring issues at them moment. Some questions in the back of my mind are: Are there any dangers in heavily depending on the parent::__construct() function to call parent classes? In the controller, is passing data from Model to View using $this->_view->foo = $this->_model->getBar(); good practice? Are there any dangers in using Namespaces? I am also interested in reading up on MVC framework best practices so if anyone can recommend some resources I would be very grateful. It seems like there are a million ways to write an MVC framework, I am confused as to which way is best practice. EDIT: Hmm, can't seem to get a list to display here...
  7. I am really struggling with the logic aspect of my application. I can't picture the structure and get it clear in my mind. As a result, I can't code anything because I'm second-guessing myself at every turn. My application is pretty simple in reality. It's an application that keeps a record of all the different 'contracts'/'agreements' that my colleagues have signed. Some will have signed three or four depending on what systems they are working on. The application will run a cron, daily, and send out an email to anyone who's contract/agreement is about to expire with an invite for them to renew it. I have already built an application that has a login system and authentication (using Laravel). It was my first Laravel effort and I did it using a tutorial from YouTube. I figured I could use the one login from that to act as the administrator for this whole application. Once the administrator is in, they will be presented with a panel to do various things. This is the part I am stuck on. What do you all think of my "logic"? Here are the basic routes (forgetting the auth stuff which is already done); /contracts - to see a list of all the contact templates out there. /contracts/{contract-id} - to view the specific contract template /contracts/create - GET and POST to be able to add new contract templates for other systems /people - view all my colleagues on one page /people/{person-id} - view a specific colleague and all the contracts they have signed /people/create - GET and POST for this too to be able to add new colleagues to the system /people/{person-id}/create-new-contract - so this would add a record in to a third table which joins info from the people table and the contracts table to make a list of unique contract agreements for each person and their expiry date. GET and POST for this as well I suppose. Even as I'm writing this, I don't know if this will be needed because I might have an emailing class that might do this job better? Hence the writing of this post! /agreements/renew/{renew-code} - This will create a new record in the table and amend the old one to show that the previous agreement has expired and that a new one for the next 365 days is in place.As you can probably tell.. I am struggling a bit. Is there any advice you can give me to help me mentally map out my application before I start coding? I just want to get it right..
  8. I want to see your opinion about OOP and Procedural. Which method has more easier to code in PHP? I'm using Procedural, but I notice PHP can read OOP as C++. Which is better for PHP? Thanks, Gary
  9. Howdy, I am writing a forum from scratch because I like to play with fire. Moving on, I can't think of the best way to store table and column names in either variables or constants. And where to store them? Maybe in a new config.php file? I thought about it and not one sane idea entered my head. I really don't like to write them each time in my DB wrapper methods since if i change the name of a table or a column, the whole thing will fall apart. Currently i have it set like this: <?php class Posts extends DB { public function list_topics_based_on_category() { return $this->select_from_table_condition('posts_id, posts_title, posts_date, author_id', 'posts', 'posts_categories_id = 1'); } public function display_contributor_name_by_id($user_id_array) { $contributor_name = $this->select_from_table_condition_user_input('username', 'users', 'id = ', $user_id_array); return $contributor_name[0]['username']; } public function count_comments($topic_id) { return count($this->select_from_table_condition_user_input('comments_id', 'comments', 'comments_topic_id = ', $topic_id)); } public function select_single_topic($topic_id) { return $this->select_from_table_condition_user_input('*', 'posts', 'posts_id = ', $topic_id)[0]; } } Please help! Thank you very much!
  10. Hi, I'm quite new to OOP PHP and i'm trying to make a dynamic insert function , i've followed an example on Stackoverflow to do so since its my first try at making something dynamic.http://stackoverflow.com/a/13333344/3559635 It works but im still quite confused about the two foreach loops , and if possible could someone explain that part to me please and or is there an easier more clean way to do this for a new guy like me? Im sending my POST values from the index.php <?php include("Database.php"); $db = new Database(); var_dump($db); $table = "users"; $whitelist = array('username', 'password'); $data = array_intersect_key($_POST, array_flip($whitelist)); if(isset($_POST['username']) AND ($_POST['password'])) { $db->postTesting($data, $table); } else { echo "Please fill in everything!"; } Database.php <?php class Database { private $connection; private $typedb = "mysql"; private $host = "127.0.0.1"; private $dbname = "oopphp"; private $username = "root"; private $password = ""; public function __construct() { try{ $this->connection = new PDO($this->typedb. ":host=".$this->host. ";dbname=".$this->dbname, $this->username, $this->password); $this->connection->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); return $this->connection; } catch(PDOException $e) { throw new Exception("Connection failed: ".$e->getMessage()); } } public function postTesting($data, $table) { try{ //var_dump($table, $data); $columns = ""; $holders = ""; foreach ($data as $column => $value) { //var_dump($column); //var_dump($value); $columns .= ($columns == "") ? "" : ", "; $columns .= $column; $holders .= ($holders == "") ? "" : ", "; $holders .= ":$column"; //var_dump($columns); //var_dump($holders); } $sql = "INSERT INTO $table ($columns) VALUES ($holders)"; //return $sql; $stmt = $this->connection->prepare($sql); //var_dump($stmt); foreach ($data as $placeholder => $value) { $stmt->bindValue(":$placeholder", $value); //var_dump($stmt); //var_dump($placeholder); //var_dump($value); } //var_dump($sql); //var_dump($stmt); $stmt->execute(); } catch(PDOException $rError) { throw new Exception("Registering Failed: ".$rError->getMessage()); } } } Im seriously confused about this part. foreach ($data as $column => $value) { //var_dump($column); //var_dump($value); $columns .= ($columns == "") ? "" : ", "; $columns .= $column; $holders .= ($holders == "") ? "" : ", "; $holders .= ":$column"; //var_dump($columns); //var_dump($holders); } Thanks in advance for the help
  11. Hi I’m looking for a standalone PHP OOP framework or code that follows best practices using - PDO prepared statements - Singleton Design Pattern Not looking for a massive library, something short and sweat straight to the point Any comments, feedback would be appreciated
  12. I wrote a Token Generator class based off the code from the following thread. It works as expected. I just want to get some more eyes on it for any feedback on improvements or problems. http://forums.phpfreaks.com/topic/298729-forgotten-password/?hl=%2Bmcrypt_create_iv&do=findComment&comment=1524084 <?php /** * Class Token * * Generates a Cryptographically Secure Pseudo Random Number Generator (CSPRNG) */ class Token { /** * Generates a pseudo-random string of bytes * * @return string */ public function getRandomBytes() { return openssl_random_pseudo_bytes(16); } /** * Convert (Encodes) binary data into hexadecimal representation * * Returns an ASCII string containing the hexadecimal representation of $randomBytes * * @param $randomBytes * @return string */ public function getEncodedToken($randomBytes) { return bin2hex($randomBytes); } /** * Decodes a hexadecimally encoded binary string * * @param $encoded_token * @return string */ public function getDecodedToken($encoded_token) { return hex2bin($encoded_token); } /** * Generate a hash value * * @param $raw_token * @return string */ public function sha256Hash($raw_token) { return hash('sha256', $raw_token); } } //---------------------------------------------------------------------------- //Test //---------------------------------------------------------------------------- $token = new Token(); /** Encode token and hash it */ $raw_token = $token->getRandomBytes(); echo $encoded_token =$token->getEncodedToken($raw_token);// Sent to User echo '<br>'; echo $token_hash = $token->sha256Hash($raw_token);// Stored in DB echo '<br>'; /** Decode token and hash it */ $raw_token = $token->getDecodedToken($encoded_token); echo $token_hash = $token->sha256Hash($raw_token);// Compare user token to DB token
  13. I have been trying to figure out a somewhat complex set of functions to handle some product price calculations and display. I was thinking that building classes may be the best solution, but I don't completely know what I am doing with that either. I was hoping someone may be able to help me figure out the best solution for all this. This site is being built within wordpress. The pages load as follows, 1. Site determines client level: If no user is logged in, it defaults to client_lvl = high, if user is logged in, client_lvl may be set to an alternate value. (high, med, low) This should be loaded just once per site visit. I created this function: function get_client_lvl () {$user_id = get_current_user_id(); global $client_lvl; If ($user_id == 0) {$client_lvl= 'high';} Else {$client_lvl=get_user_meta($user_id, wpcf-client-lvl, true); } }//End function I tried converting it to a class, but I'm not sure I am doing it correctly. class ClientLvl { public $client_lvl ='high'; private $user_id; private function __construct() { $this->user_id= get_current_user_id(); } public function get_client_lvl () //check the client level from user meta- { $this->client_lvl If ($user_id != 0) {return get_user_meta($user_id, wpcf-client-lvl, true); } The rest of the functions are based on the following arrangement. Collections have multiple products which have multiple variations. The Products have a series of multiplier values attached to them. One for each client level. It also has a multiplier type (m_type) The variants then have the item specific details such as cost of goods sold (cogs), Area, sku, and name. 2. This function is used to determine which multiplier value will be used in the calculation. Used on collection and product pages to determine which multiplier value to use for calculation based on client level f unction get_multiplier($client_lvl) { $p_high= get_post_meta(get_the_ID(),'p_high','single'); $p_med= get_post_meta(get_the_ID(),'p_med','single'); $p_low =get_post_meta(get_the_ID(),'p_low','single'); if ($client_lvl == 'med') {$prices=array('high'=>$p_high,'med'=> $p_med);} elseif ($client_lvl == 'low') {$prices=array('high'=>$p_high,'low'=> $p_low);} else {$prices=array('high'=>$p_high);} }//End function I am assuminng that if I made this a class, I should just define the p_high (med, low) values and then display them with another object creation in another function? 3.These values will be used in another function to limit the number of images that a user can select for their product. $img_min= get_post_meta(get_the_ID(),'img_min','single'); $img_max= get_post_meta(get_the_ID(),'img_max','single'); 4. These are the formulas that are used to calculate the displayed price. I am not sure how to handle the image and image+commission options as they use the number of selected images to determine the price. But if no images are selected, I want it to display "This is the price/ image. One idea I thought of was to include the echo statements inside the switch options, but Im not sure how to handle the array. If the client level is High the function will only loop through once and will not have a was now price. but if it is anything else, then it will loop through twice and will have the was now echo statement. If I didnt have the special case in the image based calculations, then the was now function would work just fine. But I'm not sure where to put the conditional echo's for those functions. function calculate_price($m_type) { global $cogs; $cogs= get_post_meta(get_the_ID(),'cogs','single'); $img_cost=10; $prices= get_multiplier(); Foreach($prices as $multiplier) { switch ($m_type) { case 'Area': $area= get_post_meta(get_the_ID(),'area','single'); $total[]= $multiplier * $area; break; case 'Image': if(isset($img_count)) {$total[]= $multiplier * $cogs * $img_count;} else {$total[]= $multiplier * $cogs ;} // Displayed as $price/ Image using $img_count break; case 'Commission': $total[]= $multiplier + $cogs; break; case 'Flat': $total[]= $multiplier; break; case 'Commission+Image': if(isset($img_count)) {$total[]= $multiplier + ($img_cost*$img_count);} else {$total[]= $multiplier; } //Display "Price: ".$multiplier. "+".$img_cost ." /image" break; case 'Price': $total[]= $multiplier * $cogs; break; }}} 5. Function that displays the price result from the previous function. Does not currently account for the image or image+commission statements. I need to create a similar function that finds the lowest calculated price of a particular product group to display on the archive page for products. function was_now($client_lvl,$m_type) { $total=calculate_price($m_type); $p1=number_format($total[0],2,'.',','); If ($client_lvl == "high") { echo "is \${$p1}"; } else { $p2=number_format($total[1],2,'.',','); echo "WAS: \${$p1}<br/>"; echo "NOW: \${$p2}"; }} 6.This is the subloop of the product page that displays the variants for that product. Not fully coded yet. (This code is currently displayed in the template file itself opposed to a function. function uc_list_product($ID,$m_type) { get_page_children($ID); echo "<table> "; while ( have_posts() ) { the_post(); ?> <tr><?php if($m_type=='Image'){ $display= 'Price '. was_now($client_lvl,$m_type); //if images are selected display price*img count } elseif($m_type=='Commission+Image'){ $display= 'Price '. was_now($client_lvl,$m_type);} //display multiplier, img cost, img count else {$display= 'Price '. was_now($client_lvl,$m_type);} echo "<td>". the_title()."</td><td>Price ".$display ."</td><td><a href='#'>Select Product</a></td></tr>" ; } echo "</table>"; wp_reset_query(); } This will probably be doable with classes, but I I'm not entirely sure how to go about that. I hope someone can help me figure this out.
  14. Good evening I hope someone would be so kind as to help me. I am completely new too php oop and I just need help with one tiny problem. I have written some code and I understand most of the concepts concerning oop in php, it's just that I am struggling with interfaces and I don't really see why it should be used if I can just create methods, but anyway I was told it is a good practice to use interfaces because one of the main reasons of oop is to re-use code, So I have implemented an interface but I can call the method with and without the implementation of the interface so I was kind of wondering, what the purpose of interfaces are? or am I doing something wrong?
