PHP - Filter Items That Have Common Properties In Js

If I have three files such as the following, and put session_start() in each, the session cookie will be domain: "mydomain.com" and path "/".  As such, the session will be shared between all three files.

http://mydomain.com/index.php
http://mydomain.com/folder1/index.php
http://mydomain.com/folder1/folder2/index.php

If I want the cookie to be unique to each file, then it seems I have several options. I could use session_name() to give the cookie a unique name for each file. I could use session_set_cookie_params() to set a unique path for each (/, /folder1, /folder1/folder2), however, the index files in the children directories will also be sent the root directories session cookie, right?  Will this cause problems? Should both approaches be implemented? Or is there another approach? Thanks

Hello,

I have two arrays:
 $questions, which has 'question_id' as one of its keys and
$assignment_questions which is a subset of $questions, pulled off my database.

Using php, I'd like to construct a 3rd array which takes my $questions array and removes from it any question that has a question_id which can be found in both $questions and $assignment_questions, in addition to the other values associated with a particular question_id.
 

For example, $questions has: question_id, solution, author (and other keys).  Is there any way to check if a particular key matches and then zap out all of the corresponding fields (solution, author, etc.)?

Thanks!

Hi,    I have the following query 

SELECT 
user_details.User_club_ID, 
user_details.fname, 
user_details.lname, 
user_details.email, 
user_details.club_No 
club.CLUBCODE, 
club.club_id
FROM user_details, club
WHERE club_id = $cid AND user_details.club_No = club.CLUBCODE AND user_status = 'active'";

which I converted to a prepared statement as 

SELECT 
user_details.User_club_ID, 
user_details.fname, 
user_details.lname, 
user_details.email, 
user_details.club_No 
club.CLUBCODE, 
club.club_id
FROM user_details, club
WHERE club_id = ? AND user_details.club_No = club.CLUBCODE AND user_status = ?";

Please note that user_status is a field in the table user_details. The original query (non -PDO) works correctly.   I want to know if this is correct and that the comparison in the WHERE clause  i.e. user_details.club_No = club.CLUBCODE is security safe. If not then how should this be modified.   Also if there is a better way to write this statement, kindly show that as well.  Thanks    Thanks all !

I'm showcasing user avatars and nicknames on the page, the mistake I did was I used session variables for that which are being set after login, now obviously those will be deleted as soon as the session is over.

So I thought of inserting the values into scalar variables instead of session variables. The problem I'm encountering is, how to make those variables available at the necessary spots on other pages?

Let's say I fetch data off the database after login inside login.php and I put the data into scalar variables, what would be common practice to make those scalar variables accessible in index.php?

Is this solution a good solution at all to make the avatar and nickname of the user permanent visible?

What would be common practice?

Hello

I have a from that updates a few things in the db, and uses "<?php echo $PHP_SELF;?>".

The form does update everything fine, however that page does not reflect it. If I refresh the page manually
I can see the new values.

Is this a common thing, and can anything be done to fix this?

__call is used when a method has been called, is there anything similar to __call but for properties?

I wanted to use __get, but that is only for private properties...

I am working on a header for a website and the code below pulls the file location for the image. I am wondering how (if possible) I could apply the repeat-x tag to the image. I know it can be done with html/css but I'm not sure how to go about it in PHP. Thanks in advance.


Code: [Select]
<?php

include 'db.php';

$result=mysql_query("SELECT location FROM header WHERE page='home'");

$row = mysql_fetch_row($result);


    echo "<img src=images/".$row[0] . "> ";
    
?>

I'm doing some basic object coding to get my head around OOP PHP, but I've come across something I can't get to work.

I've got two identical peices of code, MyClass is defined, MyClass2 is then defined as an extension of MyClass.  MyClass has three properties Public, Private and Protected.

In my first example I can access Public and Protected via a method in MyClass2, this class does NOT have a constructor.  The second example has a constructor but I cannot access Public:

Code: [Select]
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<body>
<?php
ECHO "MyClass2 does not have a constructor, Public & Protected both echo correctly from MyClass2->printHello!!!<BR>";
/**

 */
class MyClass
{
    public $public;
    protected $protected;
    private $private;
protected $varXXX;

function __construct() {
$this->public = "Public";
        $this->protected = "Protected";
        $this->private = "Private";
//$this->printHello();
}


    function printHello()
    {
echo $this->public . "!!!<BR>";
        echo $this->protected . "!!!<BR>";
        echo $this->private . "!!!<BR>";
    }
}




/**

    // We can redeclare the public and protected method, but not private
    protected $protected = 'Protected2';

        echo $this->public . "#<BR>";
        echo $this->protected . "#<BR><BR>";
        //echo $this->private . "???<BR>";
}
*/
    function printHello()
    {
        echo $this->public . "???<BR>";
        echo $this->protected . "???<BR><BR>";
        //echo $this->private . "???<BR>";
    }
}

$obj = new MyClass();
//echo $obj->public . "<BR>"; // Works
//echo $obj->protected; // Fatal Error
//echo $obj->private; // Fatal Error
//$obj->printHello(); // Shows Public, Protected and Private

$obj2 = new MyClass2();
//echo $obj2->public; // Works
//echo $obj2->private; // Undefined
//echo $obj2->protected; // Fatal Error
$obj2->printHello(); // Shows Public, Protected2, Undefined

Any ideas why I cannot access the property's contents in the second example when the only difference is that it has a constructor?

I have a bunch of quasi-static values that must be available to the application.  Most of them are set based on settings in a configuration file.  Others are based on GET, COOKIE, or SESSION values, and utilize the database to get the actual values.  The values will never be written to or modified by the application, only read.   It seems to me that I could create some sort of superclass which includes static methods and properties, and I could access any value by something like superclass::get('some.value');  I could design the class so that the values are queried from the DB or obtained from a parsed file only the first time they are requested, and for future requests, retrieved from a static property.   That being said, I have been told from more than one person that I am just doing it "wrong".   Please let me know what is wrong about it.   Thank you

Hi,

I'm not 100% sure if this is HTML, PHP or Javascript, but my best guess is PHP.

When you upload an image on Facebook, it automatically gathers the data about the image, i.e. size, device used (i.e. Canon, iPhone), title and description. It then outputs this on the page.

Is there anyway to do this with PHP, instead of having to type all the information out again and upload that with the photo to a database?

Cheers.

I need to set a deep property if it is undefined or NULL such as shown below:

function setProperty($value, stdClass $config, $p1, $p2, $p3, $p4) {
    if(!isset($config->$p1->$p2->$p3->$p4) || is_null($config->$p1->$p2->$p3->$p4)) {
        $config->$p1->$p2->$p3->$p4=$value;
    }
}

$config=json_decode(json_encode(['a'=>['b'=>['c'=>['x'=>null, 'y'=>123]], 'x'=>123],'x'=>['x'=>123], 'x'=>123]));

setProperty(321, $config, 'a','b','c','x');
setProperty(321, $config, 'a','b','c','y');

But I wish the function to work regardless of property depth and came up with the following.  Recommendations for a cleaner way?  Maybe I should be working with arrays and array_merge_recursive()?

function setProperty($value, stdClass $config, array $properties) {
    $property=array_shift($properties);
    if(!count($properties)){
        if(!isset($config->$property) || is_null($config->$property)) {
            $config->$property=$value;
        }
    }
    else {
        if(empty($config->$property) || !is_object($config->$property)) {
            $config->$property=new \stdClass();
        }
        setProperty($value, $config->$property, $properties);
    }
}

$config=json_decode(json_encode(['a'=>['b'=>['c'=>['x'=>null, 'y'=>123]], 'x'=>123],'x'=>['x'=>123], 'x'=>123]));

setProperty(321, $config, ['a','b','c','x']);
setProperty(321, $config, ['a','b','c','y']);

 

I implemented an endpoint which receives name/value pairs:

PUT someresource/123 {"name": "description", "value": "Some new description"}

I think I made a mistake, and should have implemented it as:

PUT someresource/123 {"description": "Some new description"}

The reason I think so is updating multiple properties is only (easily) possible using the later:

PUT someresource/123 {"description": "Some new description", "otherProperty": "bla bla bla"}

Assuming I am not using some 3rd party client library which only works with name/value pairs, any compelling reason why one shouldn't default to the later approach with key/values?
