PHP - Where Do I Find The Class Objects That Can Be Used With An Update Command?

I think this is what it is called...
I having a brain fart...
And I don't play with classes that much...
Plus I have been playing with trying to get pdf's to output correctly so my brain is toasty....

I'm trying to parse DICOM (medical file format) files and I have this class and I want to setup an array to pull what fields I want.


Code: [Select]
<?php
require '../dicomparser/nanodicom.php';
$filename = 'B4IBG5A0';
// 5) Load simple and print certain value
try
{
//echo "5) Load simple and print certain value\n";
$dicom = Nanodicom::factory($filename);
$dicom->parse();
//echo $dicom->profiler_diff('parse').'<br>';
echo 'Patient Name: '.$dicom->value(0x0010, 0x0010).'<br>';
echo 'Operators Name: '.$dicom->value(0x0010, 0x0040).'<br>';
echo 'Patient ID: '.$dicom->value(0x0010,0x0020).'<br>';

unset($dicom);
}
catch (Nanodicom_Exception $e)
{
echo 'File failed. '.$e->getMessage()."\n";
}
//}

?>

So what I want to do is have the array contain 'Patient Name' => '(0x0010, 0x0010)' etc...
And have it something like this so I don't have to echo all the lines I want.

Code: [Select]
foreach ($array as $key => $value) {
echo $key': '.$dicom->value.$value.'<br>';
}


I can't get it to work... I remember figuring it out once before but that was over a year ago... And I don't have the code I wrote. I know it's something simple stupid. like $$ or [] i'm not getting the combination right.

Thanks in advance...

I can post some code once I am back at my laptop but for now thinking about this is keeping me awake in bed and all I have handy is my phone.

Anyway, I am new to OOPHP. I have a class that I created. I have two objects/instances of it, each using some of the same and some different methods within the class.

When I run the page either of the instances works great alone but I get the white screen of death when I try to use both instances at the same time. Any ideas or places I should start?

Well in my script exist certain objects being used everywhere, in main script files and class library files. A good example is this Page class:

Code: [Select]
<?php
class Page{
  public $type;
  public $name;
  private $title = "";
  private $content = "";
  private $date = "";
  private $links;
  private $sidebar;
  private $ads;

  public function __construct($page = ""){
      // Constructor method of page class
  }

    public function gettitle(){
     if(empty($this->title)) throw new Exception('The page has no title.');
     return $this->title;
  }
  
  public function settitle($title){
     $title = secure($title);
     if(empty($title)) throw new Exception('Cannot set title for this page.');
 else $this->title = $title;
  }
  
  public function getcontent(){
     if(empty($this->title)) throw new Exception('The page has no content.');
     return $this->content;
  }
  
  public function addcontent($content, $overwrite = FALSE){
     $content = secure($content);
     if(empty($this->content) or $overwrite == TRUE) $this->content = $content;
 else $this->content .= $content;
  }

  public function getlinks(){
     // the method that grabs user links
  }

  public function getsidebar(){
     // the method that loads sidebar
  }

  public function getads(){
     // the method that shows ads
  }

  public function display(){
     // the method that format pages and brings everything together
  }
}
?>

Now lets say I have other classes such as User, Message and Item, a page object will need to be used inside some of their methods so that the page title/content can be modified when necessary. This seems to be quite problematic to me, since I have to declare this Page object global in every method that uses it.

Similar problem occurs with my database object, and its even more annoying since almost half of my class methods need to use database queries and commands.

So I was wondering... Is there a better way for me to handle these system objects such as Page and Database rather than having to declare them as global inside every single method that deals with them? Please help...

Hello!
I am executing an external command from a PHP script, using the exec function. Since this program can take more than 1-2 minutes to run, I thought I should use a "Loading page...please wait". What I need is to be able to get the process id from the external program that is being run and, when this finishes, I'll start outputting the results.

Is there a way to do this?

Hello all!   I have this array of objects:

Array
(
    [0] => stdClass Object
        (
            [first_name] => test
            [last_name] => test
            [title] => test
            [id] => 34
            [type] => 4
            [manager] => 4
            [email] => p@yahoo.com
            [date] => 2014-09-21 07:23:12
            [status] => 2
            [approval_date] => 2014-09-21 07:31:10
            [assessment_id] => 1
            [supervisor_approval] => 1
            [manager_approval_date] => 2014-09-21 07:31:27
            [mainmanger] => 3
        )

    [1] => stdClass Object
        (
            [first_name] => test
            [last_name] => test
            [title] => test
            [id] => 34
            [type] => 4
            [manager] => 4
            [email] => p@yahoo.com
            [date] => 2014-09-20 07:39:55
            [status] => 2
            [approval_date] => 2014-09-20 07:40:41
            [assessment_id] => 3
            [supervisor_approval] => 1
            [manager_approval_date] => 2014-09-20 07:41:07
            [mainmanger] => 3
        )

    [2] => stdClass Object
        (
            [first_name] => jimmy john john
            [last_name] => john
            [title] => Lorad and Master
            [id] => 32
            [type] => 4
            [manager] => 3
            [email] => j@j.com
            [date] => 2014-09-21 07:38:50
            [status] => 2
            [approval_date] => 2014-09-19 07:39:25
            [assessment_id] => 2
            [supervisor_approval] => 1
            [manager_approval_date] => 2014-09-19 07:39:25
            [mainmanger] => 0
        )

)

Where "id" = the user ID.    If there are two or more entries for a user, I want to remove all but the most recent by the "approval_date",... So for the above example it would return:

Array
(
    [0] => stdClass Object

            [last_name] => test

            [id] => 34
            [type] => 4
            [manager] => 4
            [email] => piznac@yahoo.com
            [date] => 2014-09-21 07:23:12
            [status] => 2
            [approval_date] => 2014-09-21 07:31:10
            [assessment_id] => 1
            [supervisor_approval] => 1
            [manager_approval_date] => 2014-09-21 07:31:27
            [mainmanger] => 3
        )

    [1] => stdClass Object
        (
            [first_name] => jimmy john john
            [last_name] => john
            [title] => Lorad and Master
            [id] => 32
            [type] => 4
            [manager] => 3
            [email] => j@j.com
            [date] => 2014-09-21 07:38:50
            [status] => 2
            [approval_date] => 2014-09-19 07:39:25
            [assessment_id] => 2
            [supervisor_approval] => 1
            [manager_approval_date] => 2014-09-19 07:39:25
            [mainmanger] => 0
        )

)

I'm having a hard time wrapping my head around this concept, so I don't have any example code. And I don't really need or expect someone to code this for me,. just a push in the right direction would be awesome.

I was looking over some code that someone else had written when I noticed a line with "$this->entity" in it.  "Entity" is recognized as PHP syntax in my text editor but I cannot find any reference to it in any documentation that I've looked through.

Where can I find more information about the "entity" class?

Thanks in advanced!

I have the following three tables (and also delta_point and hist_point which are purposely left out and just mentioned for context).  Before going down the Doctrine ORM long curvy road, aggrType was just used to restrict possible values so that I didn't need to use MySQL's ENUM, but now I am thinking there may be value to making it an entity and include some methods (and a second reason because I still can't figure out how to make Doctrine create a FK constraint yet not populate the parent entity with a AggrType object).

point
-id (int PK)
-data
-dType /* descriminator.  Options are AggregatePoint, DeltaPoint, and HistoricPoint */

aggr_point
-id (int PK, FK to point)
-aggrType (char FK to aggrType)
-data

aggrType
-type (char PK) /* there are about five types */

I have a service to create a new point based on the provided desired type and user data.  I don't like the switch statement to determine which type of point to create, but don't know a better way.  Also my entity is responsible to provide the appropriate validation rules for the given point type which might not be considered proper but it seems to work for me.  Any constructive criticism is welcomed.

<?php
namespace NotionCommotion\PointMapper\Api\Point;
use NotionCommotion\PointMapper\Domain\Entity\Point;
class PointService
{
    public function create(string $type, array $params):integer {
        $class=[
            'aggr'=>'AggregatePoint',
            'delta'=>'DeltaPoint',
            'hist'=>'HistoricPoint',
        ][$type];
        //$class='Point\\'.$class;  //This doesn't seem to be possible and I needed to use the fully qualifed name without the short cut used namespace.
        $class='\\Greenbean\Datalogger\Domain\Entity\Point\\'.$class;
        $point=new $class();
        $validator=$this->getValidator($point);
        $params=$validator->sanitize($params);
        $validator->validate($params);
        $point->setAccount($this->account);
        $point->populate($params, $this->em); //Will be addressed later
        $this->em->persist($point);
        $this->em->flush();
        $point->setIdPublic($this->em->getRepository(Point\Point::class)->getPublicId($point->getId()));
        return $point->getIdPublic();
    }
}

Now, this is the part I am struggling with the most.  I only have one service to create any type of point, so I do wish to put a bunch of if/thens in it and instead move logic to the individual point type being created.  The AggrPoint in question requires a sub-point and I don't think it is appropriate to inject the entity manager into a point entity and as an alternative solution find an existing point which is associated with the account which resides in the new AggrPoint.  Maybe not appropriate, but it works.  This type of point also has a sub-object AggrType as discussed at the very beginning of this post, so I first attempt to create a new one from scratch, but that doesn't work and I need to set $aggrType with an existing one.  As an alternative, I passed the entity the entity manager, but as stated I think this is a bad idea.

Any recommendations where to go from here?  Thank you

namespace NotionCommotion\PointMapper\Domain\Entity\Point;
class AggregatePoint extends Point
{
    public function populate(array $params, \Doctrine\ORM\EntityManager $em):\NotionCommotion\PointMapper\Domain\Entity\Entity{
        $criteria = \Doctrine\Common\Collections\Criteria::create()
        ->where(\Doctrine\Common\Collections\Criteria::expr()->eq("id_public", $params['pointId']));
        if(!$subpoint = $this->getAccount()->getPoints()->matching($criteria)->current()){
            throw new \Exception("Invalid subpoint ID $params[pointId]");
        }
        $this->setSubpoint($subpoint);

        //This won't work since I must use an existing AggregateType and not create a new one
        $aggrType=new AggregateType();
        $aggrType->setType($params['aggrType']);

        //This just seems wrong and I shouldn't be passing the entity manager to an entity
        $aggrType=$em->getRepository(AggregateType::class)->findOneBy(['type'=>$params['aggrType']]);

        $this->setAggregateType($aggrType);

        unset($params['pointId'], $params['aggrType']);
        // parent::populate($params) not shown, but it basically calles appropriate setters based on the property name
        return parent::populate($params);
    }

    public function getValidatorRules():array
    {
        return $this->filesToArr(['/point/base.json', '/point/aggr.json']);
    }

}

 

I have mysqli object in Database class base:

Please help me

Can anyone post a generic update function to update mysql table.
The manual approach:

update $tablename
set $column1='a', $column2='b'
where $id=$value;

Hi i have this simple update form and scrip but somehow it doesnt seem to be update the field on the database can someone help out please.
The html form is the second form bellow where the action send to status_update.php

Hi

Can you call Class A's methods or properties from Class B's methods?

Thanks.

If a class has a constructor but also has a static method, if I call the static method does the constructor run so that I can use an output from the constructor in my static method?

--Kenoli

I have an existing instance of my class Database, now I want to call that instance in my Session class, how would I go about doing this?

Ok. I know you can pass the object of a class as an argument. Example:


class A {
    function test() {
        echo "This is TEST from class A";
    }
}


class B {
    function __construct( $obj ) {
        $this->a = $obj;
    }

    function test() {
       $this->a->test();
    }

}


Then you could do:

$a = new A();
$b = new B($a);


Ok so that's one way i know of.

I also thought that you could make a method static, and do this: (assuming class A's test is 'static')

class B {
    function test() {
       A::test(); 
   }
}


But that is not working.


I'd like to know all possible ways of accomplishing this. Any hints are appreciated. thanks

what Im basically trying to do is just like a phpmyadmin function... you select rows you want to update with a checkbox and then it takes you to a page where the rows that are clicked are shown in forms so that you can view and edit info in them... and then have 1 submit button to update them all at once.
