PHP - Passing $_post To Object
I'm practicing my OOP skills and want to pass $_POST values to an Object's Instance Variables when a form is submitted.
This is what I have so far... index.php Code: [Select] <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> </head> <body> <!-- Registration Form --> <form method="post" action="results.php"> <!-- Registration Fields --> <div> <label for="email">E-mail:</label> <input type="text" name="email" class="txt" id="email" /> </div> <div> <label for="password">Password:</label> <input type="password" name="password" class="txt" id="password" /> </div> <div> <input type="submit" name="btnSubmit" value="Register" class="btn" id="btnSubmit" /> </div> </form> </body> </html> results.php Code: [Select] <?php include ('classes/FormHandler.class.php'); ?> FormHandler.class.php Code: [Select] <?php class HandleForm { // Define Variables. private $email; private $password; public function __construct($email, $password){ $this->email = $email; $this->password = $password; } } ?> I'm a little stuck on how I initialize the Instance Variables in the Constructor?!

I have a hidden field that holds it in each step... what am I overlooking? ok so here the deal. i have to write a script that searches a giant database of school and returns the contact info for all schools matching the search term. no big deal it's cake to code something that simple... but wait there more! the search must be executed by a joomla page... we crap. joomla doesn't allow me to run php scripts... so i found a little plugin called jumi that lets me do just that. and it works great minus all the errors joomla spits out because the mysql_connect statement and the mysql_query statment are connecting to a different database than the one joomla is installed onand thus joomla thinks the tables i am searching don't exist so joomla outputs this 4 page long error code in a bright red box a the top of the page. so i tried turning off joomls error reporting.. no bueno. so i figured no problemo i'll just have the script call out to a .php file hosted else where on the server and pass the search terms to that file via $_POST. then have said file execute a quick search of the database and return the results back to the original joomla page from whence the search commenced via a nice tidy $_POST array. one problem how in hades do you pass around php arrays via $_POST? Hi, I need to pass value of variable to another php file. I thought it is possible to do it as following: <form action="products.php"> <INPUT TYPE=hidden NAME='id' . VALUE='$id'> </form> But the problem is like that. The php file inside which I want to write above html code has not using <form> tag and it has no buttons. So how to initiate the transfer of variable into another php file? Is the above idea is not the good idea? Are there any another ways? I've been poking around the Internet for the answer to this without any success. This query APPEARS to run, but NOTHING GETS INSERTED. The QuestionID in the Questions table is set to auto-increment, so I only need the QuestionText data for this table. the QuestionID in the Answers table is not because there might be four or five options per question. The snippets of code under consideration is pasted below snipped from index.php: Code: [Select] <form action="./newquestion.php" method="post"> Question Text:<br><input type="text" size=100 name="QuestionText" /><br><br> <input type="submit" value="Enter next question"/> </form> Then snipped from newquestion.php mysql_select_db(quiz); $query = mysql_query("INSERT INTO Questions VALUES ('$_POST[QuestionText]'"); $result = mysql_query($query); Thank you all. I'm sure I'll learn this pretty fast, but I still need a little help. There's probably an obvious reason but I can't seem to find it... I start with the $_POST array, received from a form: Code: [Select] array(9) { ["Name"]=> string(3) "KTN" ["SQLServer"]=> string(24) "10.6.11.20\VSQLI028,1433" ["Username"]=> string(2) "GF" ["Password"]=> string(2) "GF" ["MasterDB"]=> string(11) "GFMaster_KN" ["Version"]=> string(3) "4.9" ["Prod"]=> string(1) "1" ["Monitored"]=> string(1) "0" ["button"]=> string(38) "updateColumnName=EnvironmentID;Value=1" } I get the button value from the array, and unset the button array value. Code: [Select] function load_POST($name) { //returns value and removes it from $_POST array. returns NULL if not existing. $debug = 0; if ( $debug == 1 ) { $backtrace = backtrace(); echo __FUNCTION__."()"; echo " <i>called by ".basename($backtrace[1]['file'])."</i><br/>\n"; } $post = NULL; if( array_key_exists($name, $_POST) ) { $post = urldecode($_POST[$name]); if ( $debug == 1 ) { echo "post $name, value: $post<br/>\n"; } } else { if ( $debug == 1 ) { echo "post $name: doesn't exist<br/>\n"; } } unset($_POST[$name]); return $post; } $_POST is now: Code: [Select] array(8) { ["Name"]=> string(3) "KTN" ["SQLServer"]=> string(24) "10.6.11.20\VSQLI028,1433" ["Username"]=> string(2) "GF" ["Password"]=> string(2) "GF" ["MasterDB"]=> string(11) "GFMaster_KN" ["Version"]=> string(3) "4.9" ["Prod"]=> string(1) "1" ["Monitored"]=> string(1) "0" } Then I create the object to assign the values to: Code: [Select] object(Environment)#1 (9) { ["EnvironmentID"]=> NULL ["Name"]=> NULL ["SQLServer"]=> NULL ["Username"]=> NULL ["Password"]=> NULL ["MasterDB"]=> NULL ["Version"]=> NULL ["Prod"]=> int(0) ["Monitored"]=> int(0) } So far so good Then, for each remaining $_POST value, I update the Object accordingly: First one, parametername: Name, parameter: KTN Code: [Select] object(Environment)#1 (10) { ["EnvironmentID"]=> NULL ["Name"]=> string(3) "KTN" ["SQLServer"]=> NULL ["Username"]=> NULL ["Password"]=> NULL ["MasterDB"]=> NULL ["Version"]=> NULL ["Prod"]=> int(0) ["Monitored"]=> int(0) ["ColumnName=EnvironmentID;Value=1"]=> object(stdClass)#3 (1) { ["ColumnName"]=> string(1) "1" } } And there we have the problem, for some reason the button value is added to the object somehow... Any ideas? Thanks in advance! Hi Guys, I'm new to OOP. I've mastered some basic syntax, but am wondering about an issue of design. To clarify in this example, I'm simply looking to pull Team data from a Database (I've not included my db class (PDO wrapper) although I know it is working. Although I have seen this sort of method below in a book (I believe and on the net) and it does work, I cannot help thinking coupling the DB class so tightly with the Team Class isn't a great approach. Can anyone give me feedback as to whether my approach is valid? While I can see the negative issue of tight coupling (i.e. changes to any database method would require multiple changes in Team (as team methods were added), I cannot really see an alternative way of doing this? I guess this is an issue of a design pattern or more advance OOP. Can anyone suggest an alternative way and/or more reading on making the coupling looser while still achieving my objectives? Should, for example, all DB functionality in getName be done during implementation? I initally thought pushing all db related functionality inside a Team method was wise and the best way then to add further methods, i.e. getResults method would be similar to getName but obviously with a different query and processing afterwards inside Team, but now I wonder if all should be in the implementation, or is there another approach? Thanks in advance.
// create team class
class Team {
private $db;
private $team_name;
private $team_id;
private $result;
// in constructor lets pass DB object
public function __construct($db) {
$this->db = $db;
}
//function to get team name
public function getName($team_id) {
$this->team_id = $team_id;
$this->db->query("SELECT team_name, nickname, founded FROM club WHERE team_id=:teamid");
$this->db->bind(':teamid', $this->team_id);
if ($result = $this->db->single());
{
return $result[];
}
}
}// end class
// Implementation
$team_id=1; //passed from user input
// First Create Db Object with correct passed variables
$database = new Database($server,$db_type);
// Invoke DB connect method
$database->connect();
// Now create Team object, pass it database object
$team = new Team($database);
// call Team method
$team_display = $team->getName($team_id);
// close db
$database->closedb();
function chk_error($site_mode, $obj)
{
if( $site_mode == 'dev' )
{
echo'Error : ('. $obj->errno .') '. $obj->error;
}
}
chk_error($site_mode, $stmt);
the above is not working for me. it echos out the text but no values for errno and error. what am i doing wrong?
I don't know why it won't work.. as the topic titles says that I am trying to pass a mysqli object to a property in another class but it keeps me getting an error.
here's the code for the mysqli object that i want to pass to another class
class ConnectMe2Db
{
public $dbname = 'somedatabase';
public $dbuname = 'root';
public $dbpass = '';
public $dbhost = 'localhost';
function __construct()
{
$mysqli = new mysqli($this->dbhost,$this->dbuname,$this->dbpass,$this->dbname)
or die ('ERROR: '.$mysqli->connect_errno);
return $mysqli;
}
# OTHER CODES...
}
and here is the class that i want the Mysqli object to pass to:
class DatabaseUsers
{
private $dbconnection;
function __construct()
{
$this->dbconnection = new ConnectMe2Db();#mysqli object will be passed to this attribute '$dbconnection'
}
public function session($username, $password)
{
$UserName = mysqli_real_escape_string($this->dbconnection,$username);
$Password = mysqli_real_escape_string($this->dbconnection,md5($password));
$querry = "SELECT * FROM trakingsystem.login WHERE username='$username' and password='$password'";
$result = mysqli_query($this->dbconnection,$querry) or die (mysqli_error($this->dbconnection));
$count = mysqli_num_rows($result);
$row = mysqli_fetch_array($result);
if ($count > 0)
{
#some code here
}
}
#some other code here
}
and this outputs 4 errors:
#outputs 2 of these: Warning: mysqli_real_escape_string() expects parameter 1 to be mysqliand some mysqli_query() expects parameter 1 to be mysqli mysqli_error() expects parameter 1 to be mysqliis there something wrong with the logic that I've made? please help thanks I everyone, I'm developing a small MVC framework for my personal work, now, in order to have access from all the classes to certain variables I've created a registry class, for this to work I have 2 options: 1.- passing every time the registry object to the constructor class(controllers, models, etc) or 2.- create in the registry static set and get so I can reach the variables by Registry::set(name, value) and Registry::get(name) My question is, which one of this two options takes less resources(is faster)? I hope anyone can help me with this, thanks in advance I work with a large codebase and I have this situation come up fairly often:
the legacy class has large objects such as:
$design->motor->dimensions->a; $design->motor->dimensions->bd; $design->specifications->weight; $design->data->height; //etcWhen I create a new class, that class sometimes operates on the specific data, so say:
class MyClass
{
public function compute($weight, $height, $a)
{
//stuff
}
}
//and I call this for example as such:
(new MyClass())->compute($design->specifications->weight, $design->data->height, $design->motor->dimensions->a);
CONS: Potential issue: if design specs change and I need to change things parameters in "compute" function, I need to "re-key" the variables I pass to the function, and adjust things accordinly in MyClass as wel.
PROS: only the exact data is being passed, and this data can come from anywhere it is viable, so in effect the function is fairly well separated, I think.
Alternative option for me is to pass the entire design object, i.e
class MyClass
{
public function compute(&$design) //can also be done via DI through a setter or constructor.
{
print $design->specifications->weight;
print ($design->data->height + $design->motor->dimensions->a);
//stuff
}
}
(new MyClass())->compute($design);
PROS: In this case when things change internally in which variables are needed and how things are computed, I only need to change the code in compute function of the class itself.
CONS: MyClass now needs to be aware of how $design object is constructed.
When it comes to this parameter passing, and Dependency Injection like this in general, does Computer Science advocate a preference on this issue? Do I pass the entire object, or do I pass only the bits and pieces I need?
Hey all, I want to have an object that has a property which is an object containing instances of other objects. I try this: Code: [Select] class Blog extends Posts { public $has_posts; public function __construct($a,$b,$c){ $has_posts = (object) array_merge((array) $a, (array) $b, (array) $c); } } class Posts { public $b; public function __construct($b){ $this->b = $b; } } $post1 = new Posts(1); $post2 = new Posts(2); $post3 = new Posts(3); $blog = new Blog($post1,$post2,$post3); var_dump($blog->has_posts); //null foreach($blog->has_posts as $post){ //Invalid argument supplied for foreach() echo $post->b; } But as you see, has_posts is null, not an object containing other objects. Thanks for response. I have a Soup object in a Bowl object in a Microwave object. The Microwave object has the methods: receiveItem(Bowl $b) cookItem(???) I want the Microwave to be able to set the Soup->temperature but I'm not how to do that? Make sense? TomTees Code: [Select] <?php $parentesco .=' <ul><li><a href="children.php?category_id='.$idc.'&name= '. $name2 . '">'. $name. ' </a></li></ul>'; ?> in the url string $idc is passing but $name2 is not. $name2 is pickup from a query, I echo that value everywhere in the code and it echo its value but is not passing so how. Help I have some function or method. Is there a better design patter to implement this?
function myFunction($a=null,$b=null,$c=null,$d=null,$e=null,$f=null,$g=null,$h=null)
{
//Do a bunch of stuff
}
Maybe the second function?
function myNewFunction($data=array())
{
$data=array_merge(array('a'=>null,'b'=>null,'c'=>null,'d'=>null,'e'=>null,'f'=>null,'g'=>null,'h'=>null),$array);
//Do a bunch of stuff
}
Please provide decision making factors why you would use one approach over the other.

For the radio button, lets just say i have the id name as 'rim' + number eg; rim0, rim1, rim2.... When i post the data to another file to execute the data collected, naturally i would use the: Code: [Select] $rim0=$_POST['rim0']; $rim1=$_POST['rim1']; .... $rim10=$_POST['rim10']; i tried to shorten this process using this method: Code: [Select] //$q is part of the post variable. for($x = 0; $x < count($q); $x++){ $rim[]=$_POST['"rim"."$x"']; } But i get this error Code: [Select] Notice: Undefined index: "rim"."$x" in D:\Apache Software Foundation\Apache2.2\htdocs\.....\#####.php on line 20 Notice: Undefined index: "rim"."$x" in D:\Apache Software Foundation\Apache2.2\htdocs\.....\#####.php on line 20 Notice: Undefined index: "rim"."$x" in D:\Apache Software Foundation\Apache2.2\htdocs\.....\#####.php on line 20 Notice: Undefined index: "rim"."$x" in D:\Apache Software Foundation\Apache2.2\htdocs\.....\#####.php on line 20 Notice: Undefined index: "rim"."$x" in D:\Apache Software Foundation\Apache2.2\htdocs\.....\#####.php on line 20 Notice: Undefined index: "rim"."$x" in D:\Apache Software Foundation\Apache2.2\htdocs\.....\#####.php on line 20 Notice: Undefined index: "rim"."$x" in D:\Apache Software Foundation\Apache2.2\htdocs\.....\#####.php on line 20 Notice: Undefined index: "rim"."$x" in D:\Apache Software Foundation\Apache2.2\htdocs\.....\#####.php on line 20 Notice: Undefined index: "rim"."$x" in D:\Apache Software Foundation\Apache2.2\htdocs\.....\#####.php on line 20 Notice: Undefined index: "rim"."$x" in D:\Apache Software Foundation\Apache2.2\htdocs\.....\#####.php on line 20 Is there something wrong with my POST syntax?
