PHP - Loading Self Made Objects In Php

Hello everyone
For a site of one of our customers our programmer created his own CMS which works OK at the site, but now the customer wants to shorten the URLS which are generated by the system. Is this easily possible? The programmer doesn't have the time to help us with it so that's why I try my luck here...
I hope somebody can help me. Thanks! 

I have this query that fully works the way it is, but I am wondering if I am overdoing some things in it.  I know this may be hard to tell without knowing the full relationship between all the tables in the query.  I'm basically running 3 subqueries mostly based on a timestamp value and other specific clauses per subquery.  Where the main query is only gathering based on the timestamp.   Like I said it works perfect from what I can verify by cross referencing the tables manually and checking the results the query returned.  I just want to know if there is a better way to do all this.

SELECT `products`.`id` AS `pid`, `products`.`prod_name`,
 
(SELECT COUNT(*) FROM `products` 
INNER JOIN `quote_deposits` ON `quote_deposits`.`product_id` = `products`.`id`
INNER JOIN `quote_responses` ON `quote_responses`.`id` = `quote_deposits`.`q_id`
WHERE `quote_responses`.`purchased` = 0 AND `quote_deposits`.`dep_date` >= $committed_start
) AS `committed`, 

(SELECT COUNT(`products`.`id`) FROM `products` 
  INNER JOIN `quote_deposits` ON `quote_deposits`.`product_id` = `products`.`id`
  INNER JOIN `quote_responses` ON `quote_responses`.`id` = `quote_deposits`.`q_id`
  WHERE `quote_responses`.`purchased` = 1 AND `products`.`id` = `pid` AND `quote_deposits`.`dep_date` >= $committed_start
) AS `total_per_item`,

(SELECT COUNT(`products`.`id`) FROM `products` 
  INNER JOIN `quote_deposits` ON `quote_deposits`.`product_id` = `products`.`id`
  INNER JOIN `quote_responses` ON `quote_responses`.`id` = `quote_deposits`.`q_id`
  INNER JOIN `schedule` ON `schedule`.`deposit_id` = `quote_deposits`.`id`
  WHERE `quote_responses`.`purchased` = 0 AND `schedule`.`cancelled` != '' AND `products`.`id` = `pid` AND `quote_deposits`.`dep_date` >= $committed_start
) AS `total_cancelled`

FROM `products`
INNER JOIN `quote_deposits` ON `quote_deposits`.`product_id` = `products`.`id`
WHERE `quote_deposits`.`dep_date` >= $committed_start
GROUP BY `products`.`prod_name` ORDER BY `products`.`prod_name` ASC

Hey guys basically with a simple script that I made I need some help with it's doing my head in.

What i'm trying to do is allow multiple filetypes to be shown by readdir, i want both .zip and .rar to be in the list, not just .zip how would i add .rar in this method as well to be visible on readdir?

<?php
$dirname = "/home/test/";
$dir = opendir($dirname);
$extension = array_pop(explode(".", $file));

?>

<?php
while(false != ($file = readdir($dir)))
{
 if ($file != "." && $file != ".." && array_pop(explode(".", $file)) == "zip") {
echo("





<b>&raquo; <a href='$dirname$file'>$file - Download</a> <br />     </b>



");
}
}

?>

Hello people! Well, I'm working on a site that has a financing simulator that asks for your data and a value related to cars, real estate and motorcycles. When simulating, it sends you to a page, calculating the closest result and sends your data to the database. However, he has a problem now. When you try to simulate, it no longer shows the result, it even loads the table but has no content, and the simulator form quickly pops up again. Check out an example at http://vitorconsorcios.com.br/simulador.php, below has the source code of the site. I've tried everything, but this is my last solution. What could be the cause of this?

 

<?php

/* if (isset($_POST['valorcon']) */
$valorcon = (int) tira_virgula_para_ponto( $_POST['valorcon'] );
$plano=anti_injection($_POST["plano"]);
$tipo=anti_injection($_POST["tipo"]);
$nomecon=anti_injection($_POST["nomecon"]);
$telefone=anti_injection($_POST["telefone"]);
$emailcon=anti_injection($_POST["emailcon"]);
$cidadecon=anti_injection($_POST["cidadecon"]);

if ($valorcon>0) {        
    // Inseri a procura

Hello,

Where can i find the source of the pre made php functions?

Greets,
Scuar.

Hi,
I have a form with a submit button (Delete button). after I click the button I do few changes in database.
Problem is that in this form, after the submit made, it still shows me old data that deleted....

So, I guess I need somehow to make a page refresh through a GET method.
How do I do this?
Thank u!

So I made a template class, it's very simple, pretty much allows the usage like so:

 $template = new template("blogpost");
 $template->fillBraces(array(
    "TITLE"  => "How to bathe your chimpanzee",
    "AUTHOR" => "Jim Bo James"
 ));
 $template->render();


Simple, uses tpl files, similar to what phpbb used a long time back, not sure if they still do.

My main goal for this is to have a file that has something like this:
{HEADER}
{MAIN_CONTENT}
{FOOTER}

and the above usage to stay the same, however that would fill the main_content part, and the header and footer would be grabbed from header/footer tpl files. Any idea on suggestions? The full class is posted below.



class template
{
    protected $_viewContents;

    function __construct($viewName)
    {
        $this->_viewContents = file_get_contents(TEMPLATE.$viewName.TEMPLATE_EXT);
        return;
    }

    function sourceOf($fileName)
    {
        return @file_get_contents(TEMPLATE.$fileName.TEMPLATE_EXT);
    }

    function fillLayout()
    {
        
    }

    function fillBraces($information, $replacement=NULL)
    {
        if (is_array($information))
        {
            foreach ($information as $key => $val)
            {
                $this->_viewContents = str_ireplace("{".$key."}", $val, $this->_viewContents);
            }
            return;
        } elseif ($replacement!=NULL)
        {
            $this->_viewContents = str_ireplace("{".$information."}", $replacement, $this->_viewContents);
            return;
        }
    }

    function render()
    {
        echo $this->_viewContents;
    }
}



Thanks!

I have a list names in a database table in MySQL that I need to repeat the same search for on my system to get the associated information. Is there a Loop command or some type of trick to making a php script search table1.row1 then table1.row2 then table1.row3 etc.

Basically using the row in the table as a variable for the other commands in the code.

I really need some direction. Thanks.

Hello, I need help with php, I don't understand what that could be , otherwise I run the page via a wampserver, I would be grateful for any kind of help.

Hi I am new to PHP and I need to create an array and add both books to the array and than loop through the array this is where I am having trouble if the price of a book is less than $20.00 output the book’s name and price if the book’s title comes after the letter R in the alphabet output the book’s title.

I am getting these error:

My code is:

<?php
class Book {
  // Properties

foreach ($book as $bookItem) {
    $price = $bookItem->price;
    // Right now $price is a string ('$xx.xx'), we need it to be numeric
    $price = (float) substr($price, 1);
    if ($price < 20) {
        echo $bookItem->title;
        echo $bookItem->price;
    }
    if (ord(strtoupper($bookItem->get_first_char())) > ord('R')) {
        echo $bookItem->title;
    }
}
 ?>

Any help will be very much appreciated

Thank you

I found it helpful to configure all my objects in one or several bootstrap scripts.  Before doing so, I would often find myself forgetting that I already had written some class which is located deep in some script and recreating it for some other need (granted, composer definitely helped in this regard, but using it wasn't always applicable).

<?php

$c=new Pimple\Container(getMySettings());

$c['pdo'] = function ($c) {
    $db = $c['settings']['mysql'];
    return new \PDO(bla);
};

$c['foo'] = function ($c) {
    return new Foo(
        $c->get('pdo')
    );
};

$c['bar'] = function ($c) {
    return new Bar(
        $c->get('foo')
    );
};

It is all good until I find myself needing to create some new instance of some class instead of just passing some common instance to whoever needs it.

class Foo
{
    private $pdo;

    public function __construct(\PDO $pdo)
    {
        $this->pdo=$pdo;
    }

    public function getSomething():SomeClass
    {
        return new SomeClass($this->getAllDataFromDB($GET['id']));
    }
}

class SomeClass
{
    private $arr;

    public function __construct(array $records)
    {
        foreach($records as $record) {
            $arr[]=new SomeOtherClass($record);
        }
    }
}

I've read that one shouldn't create new objects in a given class's constructor, and while I could instead do so in some class's method and pass the object to the given class's constructor, to me it seems to really be the same thing.  The three issues I have with this scenario a

Needing to remember that these classes exist as they are hidden deep in some classes. Makes it more difficult to replace one of the classes with some other class in the future. Some duplication of code.

Are there other compelling reasons not to do so?  Is it worth the effort to do differently?

If so, how would you recommend doing so?  My thoughts would either to use Pimple's factory() method are create my only factory which also relies on anonymous functions.  Maybe something else?

$c['someClass'] = $c->factory(function (array $record, Container $c) {
    return new SomeClass($record);
});

Thanks

In a relational database, you "link" tables together.  For example, Customer (parent) ---> Product (child)

How do you do that with Objects?

I have a "User" class and an "AddressBook" class.  A User can have zero or more Addresses (in their AddressBook).

If I create a User object and an AddressBook object, I need a way to link them up similar to how they are linked up in the database.

Make sense?!

Hi all,   I am working with the following 2 page script: https://github.com/k...hi/php-riot-api. All works well and the data is pulled via the API as intended. However, depending on the data I'm trying to display on screen, the object contains multiple values.   For example:

$r = $test->getSummoner($summoner_id,'name');
print_r($r);

outputs their ID and name: {"585897":"TheirName"}   Just as the following:

$r = $test->getSummonerByName($summoner_name);
print_r($r);

outputs username, ID, Name, profile icon ID, level, and timestamp: {"theirname":{"id":585897,"name":"TheirName","profileIconId":642,"summonerLevel":30,"revisionDate":1405652924000}}   Depending on which function I am calling (on example.php), I would like to be able to split the values so I can echo them throughout a page:   Name: <value> ID: <value> Level: <value> etc...   Any guidance would be appreciated.

I know it is often frivolous, but sometimes I can't help trying to optimize things, and use the following two methods to create either an object injected with a string or one of a set of objects.  For both cases, the class has no setters so there is no chance that the object will later be changed.  I first stated doing this in continuously running server applications which I believe makes sense, however, it has leaked over to standard HTTP requests.

Please commit good or bad on this approach. Thanks
