  • How to get a nicely formatted PHP Web Service response?

    - by Bruno
    I called an API like this: $service = new Class_Service(); $parameters = new GetClasses(); $parameters->Request = new GetClassesRequest(); $parameters->Request->SourceCredentials = new SourceCredentials(); $parameters->Request->SourceCredentials->SourceName = "Name"; $parameters->Request->SourceCredentials->Password = "Pass"; $parameters->Request->SourceCredentials->SiteIDs = array( 12 ); $classes = $service->GetClasses($parameters); var_dump($classes); And received a response like this: object(GetClassesResponse)#7 (1) { ["GetClassesResult"]=> object(GetClassesResult)#8 (6 { ["Classes"]=> object(stdClass)#9 (1) { ["Class"]=> array(25) { [0]=> object(Mi_Class)#10 (21) { ["ClassScheduleID"]=> int(15) ["Visits"]=> NULL ["Clients"]=> NULL ["Location"]=> object(Location)#11 (30) { ["BusinessID"]=> NULL ["SiteID"]=> int(12) ["BusinessDescription"]=> NULL ["AdditionalImageURLs"]=> object(stdClass)#12 (0) { } ["FacilitySquareFeet"]=> NULL Does a response normally look like this? How do I go about getting the data in a formatted manner?

  • Using Dom Objects in PHP, the default namespace is redeclared in some nodes.

    - by TomcatExodus
    I'm working on a template engine, having migrated from regex driven to DOM driven. It appears though, that whenever I create a DomDocumentFragment to encapsulate some portion of a document temporarily, the namespace attribute is added to each node in the fragment. Since my default namespace for a given document will 99% of the time be XHTML, it's adding the XHTML namespace declaration. Being the default namespace, this seems fruitless, and ultimately nodes in any other namespace will be stripped out at render time anyways. Aside from iteratively removing namespace attributes, is there some way I can prevent this from occurring to begin with? Its quite problematic, as this will likely increase render time filesize considerably, as large portions of a given document may be stored in a fragment. I've tried $doc->normalizeDocument(), but as I assumed, it did nothing.

  • How can I overlay a watermark on an already resampled image in PHP (using GD) ?

    - by Rick
    Here's my current code: define('IMG_WIDTH', (isset ($_GET['width'])) ? (int) $_GET['width'] : 99); define('IMG_HEIGHT', (isset ($_GET['height'])) ? (int) $_GET['height'] : 75); $image = imagecreatefromjpeg($_GET['image']); $origWidth = imagesx($image); $origHeight = imagesy($image); $croppedThumb = imagecreatetruecolor(IMG_WIDTH, IMG_HEIGHT); if ($origWidth > $origHeight) { $leftOffset = ($origWidth - $origHeight) / 2; imagecopyresampled($croppedThumb, $image, 0, 0, $leftOffset, 0, IMG_WIDTH, IMG_HEIGHT, $origHeight, $origHeight); } else { $topOffset = ($origHeight - $origWidth) / 2; imagecopyresampled($croppedThumb, $image, 0, 0, 0, $topOffset, IMG_WIDTH, IMG_HEIGHT, $origWidth, $origWidth); } It basically takes an image and re-sizes it to create a thumbnail. It works quite nicely. What I would like to do now is add a watermark to the bottom right corner. I've seen the imagecopymerge function used for this... However, that doesn't seem to allow me to supply a resampled image as the source. How can I take my already modified image and add a watermark? :/ I've thought of saving the image to /tmp and then unlink()'ing it once I've added the watermark but that seems like a bit of a mess...

  • How to prevent users to change url parameter in PHP?

    - by Sachin
    I am developing a site where I am sending parameters like ids by url. I have used urlencode and base64encode to encode the parameters. My problem is that how can I prevent the users or hackers to play with url paramenters Or give access only if the parameter value is exist in database? I have at least 2 and at most 5 parameter in url so is this feasible to check every parameter is exist in database on every page? Thanks

  • Drawing up a session value within SQL query? PHP and MySQL

    - by Derek
    Hi, on one of my web pages I want my manager user to view all activities assigned to them (personally). In order to do this, I need something like this: $sql = "SELECT * FROM activities WHERE manager = $_SESSION['SESS_FULLNAME']"; Now obviously this syntax is all wrong, but because I am new to this stuff, is there a way I can call up the full name from the user's session within a query? This is so that when I call up the database values to be displayed within the web page, only the activities for the manager who is logged in is displayed. For example, the activities table has a manager column of a full name entry. Any help is much appreciated. Thanks.

  • PHP export to text file - Only saving first line.

    - by wertz8090
    I'm trying to export some extracted $_POST information into a text file, however my code is only capturing the first variable and ignoring the rest. I'm saving the information to the text file in this manner: $values = "First Name: $fName\r\n"; $values .= "Last Name: $lName\r\n"; $values .= "Address: $address\r\n"; etc. This is the code I use to write to the text file: $fp = @fopen("person.data", "w") or die("Couldn't open person.data for writing!"); $numBytes = @fwrite($fp, $values) or die("Couldn't write values to file!"); @fclose($fp); Any ideas on why it would only save the first $values ($fName) variable but not the rest of them? It actually saves the first part of the $values string for all of them (so I see Last Name:, Address:, etc. on separate lines in the text file) but the called variables $lName and $address do not appear.

  • Scalably processing large amount of comlpicated database data in PHP, many times a day.

    - by Eph
    I'm soon to be working on a project that poses a problem for me. It's going to require, at regular intervals throughout the day, processing tens of thousands of records, potentially over a million. Processing is going to involve several (potentially complicated) formulas and the generation of several random factors, writing some new data to a separate table, and updating the original records with some results. This needs to occur for all records, ideally, every three hours. Each new user to the site will be adding between 50 and 500 records that need to be processed in such a fashion, so the number will not be steady. The code hasn't been written, yet, as I'm still in the design process, mostly because of this issue. I know I'm going to need to use cron jobs, but I'm concerned that processing records of this size may cause the site to freeze up, perform slowly, or just piss off my hosting company every three hours. I'd like to know if anyone has any experience or tips on similar subjects? I've never worked at this magnitude before, and for all I know, this will be trivial to the server and not pose much of an issue. As long as ALL records are processed before the next three hour period occurs, I don't care if they aren't processed simultaneously (though, ideally, all records belonging to a specific user should be processed in the same batch), so I've been wondering if I should process in batches every 5 minutes, 15 minutes, hour, whatever works, and how best to approach this (and make it scalable in a way that is fair to all users)?

  • CodeIgniter -- unable to use an object

    - by Smandoli
    THE SUMMARY: When I call .../index.php/product, I receive: Fatal error: Call to a member function get_prod_single() on a non-object in /var/www/sparts/main/controllers/product.php on line 16 The offending Line 16 is: $data['pn_oem'] = $this->product_model->get_prod_single($product_id); Looks like I don't know how to make this a working object. Can you help me? THE CODE: In my /Models folder I have product_model.php: <?php class Product_model extends Model { function Product_model() { parent::Model(); } function get_prod_single($product_id) { //This will be a DB lookup ... return 'foo'; //stub to get going } } ?> In my /controllers folder I have product.php: <?php class Product extends Controller { function Product() { parent::Controller(); } function index() { $this->load->model('Product_model'); $product_id = 113; // will get this dynamically $data['product_id'] = $product_id; $data['pn_oem'] = $this->product_model->get_prod_single($product_id); $this->load->view('prod_single', $data); } } ?>

  • PHP extend a class method that is called from another class which extends it and calls the method wi

    - by dan.codes
    I am trying to extend a class and override one of its methods. lets call that class A. My class, class B, is overiding a protected method. Class C extends class A and Class D extends class C. Inside of Class D, the method I am trying to overwrite is also extended here and that calls parent::mymethodimoverriding. That method does not exist in class C so it goes to it in class A. That is the method I am overiding in class B and obviously you can't extend A with B and have those changes show up in D since it does not fall in line with the class hierarchy. I might be wrong, so correct me please. so if my class b is called and ran then class D gets called it runs the method in A and overwrites what I had set. I am thinking there must be a way to get this to work, I am just missing something. here is an example, as you can see in class A there is a call to setTitle and it is set to "Example" In my class I set it to "NewExample". My class is getting called before class D so when class D is called it goes back to the parent and sets the title back to "Example" class A{ protected function _thefunction(){ setTitle("Example"); } } class B extends A{ protected function _thefunction(){ My new code here setTitle("NewExample"); } } class C extends A{ nothing that matters in here for what I am doing } class D extends C{ protected function _thefunction(){ parent::_thefunction(); additional code here } }

  • codeigniter cron job with http access

    - by user1313850
    Sorry if this is a duplicate question...I've searched around and found similar advice but nothing that helps my exact problem. And please excuse the noob questions, CRON is a new thing for me. I have a codeigniter script that scrapes the html DOM of another site and stores some of that in a database. I'd like to run this script at a regular interval. This has lead me to looking into cron jobs. The page I have is at myserver.com/index.php/update I realize I can run a cron job with curl and run this page. If I want to be a bit more secure I can put a string at the end like: myserver.com/index.php/update/asdfh2784fufds And check for that in my CI controller. This seems like it would be mostly secure, but doesn't seem like the "right" way to do things. I've looked into running CI from the command line, and can execute basic pages like: php index.php mycontroller But when I try to do: php index.php update It doesn't work. I suspect this is because it needs to use HTTP to scrape the DOM of the outside page. So, my question: How do I securely run a codeigniter script with a cron job that needs HTTP access?

  • PHP Access property of a class from within a class instantiated in the original class.

    - by Iain
    I'm not certain how to explain this with the correct terms so maybe an example is the best method... $master = new MasterClass(); $master->doStuff(); class MasterClass { var $a; var $b; var $c; var $eventProccer; function MasterClass() { $this->a = 1; $this->eventProccer = new EventProcess(); } function printCurrent() { echo '<br>'.$this->a.'<br>'; } function doStuff() { $this->printCurrent(); $this->eventProccer->DoSomething(); $this->printCurrent(); } } class EventProcess { function EventProcess() {} function DoSomething() { // trying to access and change the parent class' a,b,c properties } } My problem is i'm not certain how to access the properties of the MasterClass from within the EventProcess-DoSomething() method? I would need to access, perform operations on and update the properties. The a,b,c properties will be quite large arrays and the DoSomething() method would be called many times during the execuction of the script. Any help or pointers would be much appreciated :)

  • Can I use string concatenation to define a class CONST in PHP?

    - by selfsimilar
    I know that you can create global constants in terms of each other using string concatenation: define('FOO', 'foo'); define('BAR', FOO.'bar'); echo BAR; will print 'foobar'. However, I'm getting an error trying to do the same using class constants. class foobar { const foo = 'foo'; const foo2 = self::foo; const bar = self::foo.'bar'; } foo2 is defined without issue, but declaring const bar will error out Parse error: syntax error, unexpected '.', expecting ',' or ';' I've also tried using functions like sprintf() but it doesn't like the left paren any more than the string concatenator '.'. So is there any way to create class constants in terms of each other in anything more than a trivial set case like foo2?

  • checking is username exists on two tables PHP PDO?

    - by PHPLOVER
    Me again. I have a users table and a users_banlist table. On my registration form i want to check all in one query whether the username someone entered on form exists in the users table and see if it also exists on the users_banlist table. I can do them on there own in individual queries but would rather do it all in one. Here is what i got, but even thou i enter a username that is taken it does not tell me its already taken. $stmt = $dbh->prepare(" SELECT users.user_login, users_banlist.user_banlist FROM users , users_banlist WHERE users.user_login = ? OR users_banlist.user_banlist = ?"); // checker if username exists in users table or users_banlist table $stmt->execute(array($username, $username)); if ( $stmt->rowCount() > 0 ) { $error[] = 'Username already taken'; } Basically i think it is something to do with the execute or rowCount(), could anyone tell me where i am going wrong ? being new to pdo im finding it a little confusing at the moment until i get my pdo book delivered to learn pdo. Thank you as always, phplover
