  • ASP.NET or PHP: Is Memcached useful for storing user-state information?

    - by hamlin11
    This question may expose my ignorance as a web developer, but that wouldn't exactly be a bad thing for me now would it? I have the need to store user-state information. Examples of information that I need to store per user. (define user: unauthenticated visitor) User arrived to the site from google/bing/yahoo User utilized the search feature (true/false) List of previous visited product pages on current visit It is my understanding that I could store this in the view state, but that causes a problem with page load from the end-users' perspective because a significant amount of non-viewable information is being transferred to and from the end-users even though the server is the only side that needs the info. On a similar note, it is my understanding that the session state can be used to store such information, but does not this also result in the same information being transferred to the user and stored in their cookie? (Not quite as bad as viewstate, but it does not feel ideal). This leaves me with either a server-only-session storage system or a mem-caching solution. Is memcached the only good option here?

  • Basic class returns object reference instead of Array

    - by php-b-grader
    I have very basic class: class Customer { protected $id; protected $customer; public function __construct($customer_id) { $this->id = $customer_id; return $this->set_customer(); } protected function set_customer() { $query = mysql_query("SELECT * FROM customer WHERE id = '$this->id'"); $this->customer = mysql_fetch_row($query); return $this->customer; } } $customer = new Customer($order->customer->id); print_r($customer); This is not doing what I want it to but I understand why... $customer returns a reference to the Customer Object... What I want is the MySQL row array from the mysql_fetch_row() - How do I return the array? What am I missing?

  • 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); } } ?>

  • 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?

  • transforming flat php array into multidimensional one based on key value?

    - by PopRocks4344
    I have a flat array that I'm trying to make multidimensional. Basically, I want to find the items that have parents and create a subarray for that parent id. Right now (and this is simplified), it looks like this: Array ( [0] => stdClass Object ( [id] => 1 [parent] => 0 [name ] => Parent1 ) [1] => stdClass Object ( [id] => 7 [parent] => 1 [name] => Child1 ) [2] => stdClass Object ( [id] => 9 [parent] => 1 [name] => Child2 ) [3] => stdClass Object ( [id] => 2 [parent] => 0 [name ] => Parent2 ) [4] => stdClass Object ( [id] => 88 [parent] => 2 [name] => Childof2 ) ) I'm trying to make this: Array ( [0] => stdClass Object ( [id] => 1 [parent] => 0 [name ] => Parent1 [children] => stdClass Object ( [1] => stdClass Object ( [id] => 7 [parent] => 1 [name] => Child1 ) [2] => stdClass Object ( [id] => 9 [parent] => 1 [name] => Child2 ) ) ) [1] => stdClass Object ( [id] => 2 [parent] => 0 [name ] => Parent2 [children] => stdClass Object ( [0] => stdClass Object ( [id] => 88 [parent] => 2 [name] => Childof2 ) ) ) )

  • .tpl files and website problem

    - by whitstone86
    Apologies if the title is in lowercase but it's describing an extension format. I've started using Dwoo as my template engine for PHP, and am not sure how to convert my PHP files into .tpl templates. My site is similar to, but not the same as, http://library.digiguide.com/lib/programme/Medium-319648/Drama/ with its design (except colour scheme and site name are different, plus it's in PHP - so copyright issues are avoided here, the design arguably could be seen as parody even though the content is different. The database is called tvguide, and it has these tables: Programmes House M.D. Medium Police Stop! American Dad! The tablenames of the above programmes are: housemdonair mediumonair policestopair americandad1 Episodes The tablenames for the above programmes' episode guides are: housemdepidata mediumepidata policestopepidata americandad1epidata All of them have the following rows: id (not an auto-increment, since I wish to dynamically generate a page from this) episodename seriesnumber episodenumber episodesynopsis (the above four after id do exactly as stated) I have a pagination script that works, it displays 20 records per page as I want it to. This is called pmcPagination.php - but I won't post it in full since it would take up too much space. However, I'm trying to get it so that variables are filled in like this: (ok, so the examples below are ASP.NET, but if there's a PHP/MySQL equivalent I would gratefully appreciate this!!): http://library.digiguide.com/lib/episode/741168 http://library.digiguide.com/lib/episode/714829 with the episode detail and data. My site works, but it's fairly basic, and it's not online yet until my bugs are fixed. Mod_rewrite is enabled so my site reads as http://mytvguide.com/episode/123456 or http://mytvguide.com/programme/123456 http://mytvguide.com/WorldInAction/123456/Documentary/ I've tried looking on Google, but am not sure how to get this TV guide script to work at its best - but I think .tpl, and .php/MySQL is the way to go. Any advice anyone has on making this project into a fully workable, ready to use site would be much appreciated, I've spent months refining this project! P.S. Apologies for the length of this, hope it describes my project well.

  • PHP mysql - ...AND column='anything'... ?

    - by Nike
    Is there any way to check if a column is "anything"? The reason is that i have a searchfunction that get's an ID from the URL, and then it passes it through the sql algorithm and shows the result. But if that URL "function" (?) isn't filled in, it just searches for: ...AND column=''... and that doesn't return any results at all. I've tried using a "%", but that doesn't do anything. Any ideas?

  • 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

    Hey, I have two tables in one DB, one called Cottages and one called Hotels. In both tables they have the same named fields. I basically have a search bar that i want it to search in both of the fields in both of the tables.

  • Why did I get a 400 Bad Request when getting a page with PHP Curl?

    - by user307272
    Hi, I was trying to access a page using curl. I could access it perfectly using the browser and using "static" strings as the URL, like: $url = "http://www.example.com/?q=1234" But when I tried to access the page using a variable in the URL string like: $url = "http://www.example.com/?q=$param" I got a 400 error code. I checked out on the web and found some comments here in this stackoverflow thread: Then, just for curiosity I did the following: $url = "http://www.example.com/?q=" . trim($param); and it worked! And no, $param did NOT contain any spaces. To me, it seems that it can be some encoding error, but I really can't find an explanation for it. Does anyone here in stackoverflow know what it can possibly be? Thanks in advance :)

  • 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.

  • How to generate all permutations of a string in PHP ?

    - by Johan
    I need an algorithm that return all possible combination of all characters in one string. I've tried: $langd = strlen($input); for($i = 0;$i < $langd; $i++){ $tempStrang = NULL; $tempStrang .= substr($input, $i, 1); for($j = $i+1, $k=0; $k < $langd; $k++, $j++){ if($j > $langd) $j = 0; $tempStrang .= substr($input, $j, 1); } $myarray[] = $tempStrang; } But that only returns the same amount combination as the length of the string. Say the $input is = "hey", the result would be: hey, hye, eyh, ehy, yhe, yeh.
