  • mysql_fetch_object on complex objects

    - by Arsenal
    Say for example I have the follwoing DB structure Table book id title ... Table Author id name ... Table BookAuthor id bookid authorid And in PHP I have the following object class Book { var $id; var $title; var $authors = array(); function Book() {} } class Author { var $id; var $name; function Author(){} } Now, would it be possible using mysql_fetch_object to retrieve the bookobject including the authors as an array of author objects? If it's possible I'm pretty sure you'll need the basic inner join query SELECT * FROM tblbook INNER JOIN tblbookauthor on ... (wel you get the point) Is it possible? thanks!

  • Can a function/class know the context from where it is being invoked or instantiated?

    - by vrode
    Let's take this class as example and assume that get_context() returns the source of the call: class A { public function __construct( ) { if( get_class( get_context( ) ) == B ) { return true; } else { return false; } } } class B { function __construct( ) { $a = new A( ); } } $a = new B( ); // returns true, as B is the invoking class of A $a = new A( ); // returns false, as B is invoked outside of any class So, my questions are: 1) can a function know the context that calls it? 2) can a object know context from where it has been instantiated? Or am I dreaming up new features not implementable in PHP?

  • include() Why should I not use it?

    - by aliov
    I am working through an older php mysql book written in 2003. The author uses the include() function to construct html pages by including header.inc, footer.inc, main.inc files, etc. Now I find out that this is not allowed in the default ini settings, (allow_url_include is set to Off) after I got many warnings from the server. I noticed also that you can use include without the parenthesis. I tried this and it works and I get no error messages or warnings. Are the two different? That is, is include() different from include ?

  • usage of intval & real_escape_string when sanitizing integers

    - by paulus
    dear All. I'm using integer PKs in some tables of mysql database. Before input from PHP script, I am doing some sanitizing, which includes intval($id) and $mysqli-real_escape_string(). The queries are quite simple insert into `tblproducts`(`supplier_id`,`description`) values('$supplier_id','$description') In this example, $description goes through real_escape_string(), while $supplier_id only being intval()'ed. I'm just curious, if there're any situations, when I need to apply both intval and real_escape_string to integer I'm inserting into DB? So basically do I really need to use? $supplier_id = intval($mysqli->real_escape_string($supplier_id)); Thank you.

  • How do I make a multiple file upload?

    - by Bluemagica
    I am trying to make a multiple image uploader. The file upload fields are being added in the form dynamically using jquery. I tried making an array of the fields since I don't want to have a hidden field. so my generated upload fields look like <input type="file" id="img0" name="img[]"/> <input type="file" id="img1" name="img[]"/> <input type="file" id="img2" name="img[]"/> ..... .. And on the php side I did something like if(isset($_FILES['img'])) { foreach($_FILES['img'] as $k=>$v) { if($v!="") { uploadImage($k,0,0,0,"content/gallery/"); } } } Now I know I am way too wrong, since in that code I am looping through the 'img' file's properties instead of all images....but I have no idea how to fix this. PS: uploadImage is a function I wrote which expects the file input field's name as the first parameter.

  • server side of adsense

    - by dole
    Hi there Google ask you to add a javascript code to your page and it will generate the links. The script has some id which are sent to the server, but I don't know how. <script type="text/javascript"><!-- google_ad_client = "ca-pub-1234567890123456"; /* snipet_name */ google_ad_slot = "123456789"; google_ad_width = 728; google_ad_height = 90; //--></script><script type="text/javascript" src="http://pagead2.googlesyndication.com/pagead/show_ads.js"></script> I'm curious to know how the client and slot ids are send to the server. Javascript is client side and I wish to know how those parameters are sent to the server in order to query a db and to return the links. A link, sample, explanation related to PHP will work great for me. TY

  • Command Prompt closes on Windows, using Wamp Server commands

    - by Sid
    Hey guys, I am following the tutorial on PHP with MySQL. In that tutorial ebook, they recommend us to use commands to set password for the MySQL. The command goes something like this, "mysqladmin -u root -p status" Now, I am using Windows XP and whenever I enter the command, the dos screen flashes and terminates. I am unable to note down the results, so the question: is there any way to stop command prompt from terminating on Windows machine? Looking forward to hear from you guys, thank you!

  • Send data to server with GET

    - by coderjoe
    I have made a site where all my highscores from my game are shown. I send the scores from my iphone game to my site using a script made with php. The script works, because if I enter the link produced by my app in my browser the score is added. However I want to send the scores from my app. The script is using the GET method to get name, scores etcetera. This is what i have now: NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:urlString]]; NSError * e; NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:&e]; But it's not sending data to my server. The urlString is correct, because if I enter the link produced by my app in my browser the score is added. How can i solve this problem, Thanks in advance

  • How do I modify a string printed by a script?

    - by Liso22
    I'm having problems with wordpress mishandling accented characters, or maybe the problem is with some plugin. Whichever the case I need to "translate" some strings, removing accents which i do with: $value = strtr($value, $trans); I really need to change this string which renders the user's location but it's printed with a script so I have no idea how to do it: <script language="javascript"> document.write('' + geoip_city() +''); </script> Is there a way to assign it's result to a php value beforehand or something? Maybe removing the accents with a script. I really need to modify it, how could I manage to do it? Thanks

  • Getting ftp_put progress

    - by Billiam
    I have a php script on a web server that uploads a file to another remote server via ftp_put. How can I display the current upload progress to the user? The only similar system I've seen is for file uploads from the user, with ajax requests to check the local size of the uploaded file on the server. The equivalent system would be ajax requests to the web server, that then checked file sizes on the remote server and returned that data to the user's clientscript. This seems horribly inefficient to me. Is there a better way?

  • Static variable for optimization

    - by keithjgrant
    I'm wondering if I can use a static variable for optimization: public function Bar() { static $i = moderatelyExpensiveFunctionCall(); if ($i) { return something(); } else { return somethingElse(); } } I know that once $i is initialized, it won't be changed by by that line of code on successive calls to Bar(). I assume this means that moderatelyExpensiveFunctionCall() won't be evaluated every time I call, but I'd like to know for certain. Once PHP sees a static variable that has been initialized, does it skip over that line of code? In other words, is this going to optimize my execution time if I make a lot of calls to Bar(), or am I wasting my time?

  • Suggest encoding which removes slashes which I can use as the format for REST-style URL-paramteters

    - by Binary255
    Given a path to a REST style URL: http://site.com/rest/customer/foo/robot/bar/1 When you GET it, it returns a PDF to the foo-customer containing page 1 of the bar-URL. While foo is the name of the customer bar is an URL. The URL usually contains slashes and might look something like this: http://anothersite.com/interestingarticle.html As REST URL's separate arguments by slashes I can't just put it into the REST URL above. Which encoding should I use? I can't use Base 64 as it utilizes the slash as well. As a technical note I will encode the URL in a .NET-application and decode it in PHP.

  • CakePHP: How do I change page title from helper?

    - by Zeta Two
    Hello! I'm using a helper for static pages to add a part to the title on every page. Currently I have the following code at the top of every static page: <?php $this->set('title_for_layout', $title->output('Nyheter')); ?> The purpose of $title-output is to append " :: MY WEB SITE NAME". This works fine, but for simplicity I would rather just call: $title->title('Nyheter'); At the top of every page to set the title. The problem is that I can't call $this-set() from within the helper. Is there a way to something like this or am I completely on the wrong path here?

    - by Zegnhabi
    First of all, I have some time reading this page and I find very interesting, the content also has many questions and are very entertaining. My question is about handling my incoming mail server, no matter if you use PHP, Perl, or Python. I do not care, what if I want is the result which should be as close to: I send an email to [email protected], this post will add a case such as photos, then when the mail reaches the server, the server takes to process mail and copy the attached files, in this case the photos to a folder / home / public_html / photos and then, if possible notify you if it was successful or not. In advance thank you very much. And I hope and can be done. ñ_ñ

  • 3-clique counting in a graph

    - by Legend
    I am operating on a (not so) large graph having about 380K edges. I wrote a program to count the number of 3-cliques in the graph. A quick example: List of edges: A - B B - C C - A C - D List of cliques: A - B - C A 3-clique is nothing but a triangle in a graph. Currently, I am doing this using PHP+MySQL. As expected, it is not fast enough. Is there a way to do this in pure MySQL? (perhaps a way to insert all 3-cliques into a table?)

  • How can I determine what text on a webpage will render the largest?

    - by TMG
    I'd like to write a function (ideally in PHP) where I can input a url and return a string corresponding to the hypertext from that webpage which would render the largest in a browser (any standard browser is fine). Getting the webpage and tokenizing things with DOM is pretty straightforward, but what's the best way to calculate ultimate size of the rendered text tokens - how do you account for CSS that includes px, em, % etc. for different font sizes. Anyone done something like this before I go and re-invent the wheel? Thanks in advance.
