  • Approaches for memcached sessions

    - by Industrial
    Hi everybody, I was thinking about using memcached to store sessions instead of mySQL, which seemed like a good idea, at first. When it comes to the failover part of utilizing memcached servers, It's a bit worrying that my sessions will stop working if the memcached would go offline. It will certainly affect my users. There's a few techniques that we already utilize to reduce failover, including having a pool of servers available to compensate in the event of downtime, utilizing sharding/consistent hashing across the server pool and so on. We would also do some sort of graceful degradation that tells the users that something have gone wrong and they are welcome to login again, in the event of them being kicked out due to memcached server failover. So how does people generally deal with these issues when storing sessions on memcached servers?

  • Adding Parameters to Zend_Navigation

    - by Grant Collins
    I have a problem with Zend_Navigation that I am hoping for a little guidance on. I'm in the process of adding a Zend_Navigation to a legacy app as described [here on SO].1 The thing that I am not sure of is how to add parameters to the navigation menu after the data is loaded from the xml file. What I want to do is get 2 identifying parameters from the url and add them to the Zend_Navigation so that they are included in things such as the breadcrumb bar, so that if a user selects the previous item in the breadcrumb they are returned with the correct params in the url. The parameters, I believe need to be set at the Action level rather than the controller. Any help would be appreciated. Many thanks.

  • CodeIgniter - Post multiple arrays to controller

    - by Bobe
    I have a dynamically generated form that allows users to enter new data and edit existing data. When the form is submitted, it collates the input values and groups them according to whether they are new or not, the former being denoted by class="new-entry". So the function generates two arrays: updateData and insertData. Both arrays are of similar formats: [ 0: { 'id' = 1, 'value' = foo }, 1: { 'id' = 1, 'value' = 'bar' }, etc... ] I am combining them into a new array object to send via ajax to the controller: var postData = { 'update_data': updateData, 'insert_data': insertData }; Then in the ajax call: $.post(url, postData, function() { // some code }); However, in the controller, doing print_r($this->input->post()) or print_r($_POST) as a test only returns Array(). Even $this->input->post('update_data') returns nothing. How can I retrieve these arrays in the controller?

  • WHERE clause confusion with PDO

    - by Greg
    I'm having some trouble understanding how to use prepared statements, when you need to match one value against several columns at once. In other words what instead of doing this: $stmt = $dbh-prepare("SELECT * FROM REGISTRY where name = ?"); $stmt-bindParam(':name', $name); I wanted to do this: $stmt = $dbh-prepare("SELECT * FROM REGISTRY where firstname = ? or lastname = ?"); with both '?' representing the same string.

  • Panoramio API access using AJAX - error "Origin hxxp://foo.bar is not allowed by Access-Control-Allow-Origin."

    - by Marko
    Hello there! I am currently experiencing this issue, and am wondering why...? The error message is: "XMLHttpRequest cannot load http://www.panoramio.com/wapi/data/get_photos?v=1&key=dummykey&tag=test&offset=0&length=20&minx=-30&miny=0&maxx=0&maxy=150&callback=?. Origin hxxp://foo.bar is not allowed by Access-Control-Allow-Origin. test_panoramio.html:59Uncaught SyntaxError: Unexpected token )" "hxxp://foo.bar" refers to the site I am running the script from. The "test_panoramio.html" on the site contains e.g. the following : var url = "http://www.panoramio.com/wapi/data/get_photos? v=1&key=dummykey&tag=test&offset=0&length=20&minx=- 30&miny=0&maxx=0&maxy=150&callback=?"; function myScriptFn() { if (window.XMLHttpRequest) { myAjax = new XMLHttpRequest(); if ( typeof myAjax.overrideMimeType != 'undefined') { myAjax.overrideMimeType('text/xml'); } } else if (window.ActiveXObject) { myAjax = new ActiveXObject("Microsoft.XMLHTTP"); } else { alert('The browser does not support the AJAX XMLHttpRequest!!!'); } myAjax.onreadystatechange = function() { handleResponse(); } myAjax.open('GET', url, true); myAjax.send(null); } function handleResponse() { if (myAjax.readyState == 4){ // Response is COMPLETE if ((myAjax.status == 200) || (myAjax.status = 304)) { // do something with the responseText or responseXML processResults(); }else{ alert("[handleResponse]: An error has occurred."); } } } function processResults() { myObj = eval( '(' + myAjax.responseText + ')' ); ... doSomething() ... } The Panoramio URL works if typed directly to the browser. Please could you help me with this, I am running out of hope...:( Thank you in advance, Yours Marko

  • Anyone have experience integrating with MYOB?

    - by 1nsane
    Looking to integrate a web application with MYOB. There's not much in terms of documentation out there. I've found a couple of companies that provide middleware, but nothing promising. Just thought I'd see if anyone else out there has had experience with this and might be able to save me a bit of time. Cheers

  • Getting OpenID to work on an existing MyBB Install

    - by Djdoubt03
    I am the administrator for a forum,The Vortex. It operates on the latest version of MyBB ver1.6.3. I would like to know how I can get OpenID to become the login for the forums, and also add the users to the MyBB Sql file and overwrite any users that are already registered. This must work on an existing install as I will not be dumping my SQL database to do a fresh install just to get OpenId to work. Any Thought?

  • paypal IPN sends two different twice

    - by Patrick
    I've come across something a bit strange I was hoping someone with more experience with Paypal can explain, Specifically the IPN feature. It seems I'm getting two very different hits to my IPN listener. The first one always fails, The second one passes. Now I know Paypal tends to send duplicates, But what I've noticed is two very different $_POST arrays being recieved. Here's the respones : [2014-06-08 23:51:19] RAW POST DATA : Array ( [transaction] => Array ( [0] => ILS 20.00 ) [payment_request_date] => Sun Jun 08 13:52:12 PDT 2014 [return_url] => MY_URL [fees_payer] => EACHRECEIVER [ipn_notification_url] => MY_URL [sender_email] => [email protected] //fake email [verify_sign] => ANp5TpLat3.2ylx.cECtVZ..5HejAsVcs05tdVC7RldmeYNJ91SKaqFJ [test_ipn] => 1 [cancel_url] => MY_URL [pay_key] => AP-04B74091M7083584A [action_type] => PAY [transaction_type] => Adaptive Payment PAY [tracking_id] => 13 // This is a number I passed, But it doesn't exist in the 2nd POST [status] => COMPLETED [log_default_shipping_address_in_transaction] => false [charset] => windows-1252 [notify_version] => UNVERSIONED [reverse_all_parallel_payments_on_error] => false ) [2014-06-08 23:51:19] RAW POST DATA : Array ( [transaction_subject] => [payment_date] => 13:52:28 Jun 08, 2014 PDT [txn_type] => web_accept [last_name] => test [residence_country] => US [item_name] => .... (this continues for quite a bit more) .... [payment_fee] => [mc_fee] => 1.78 [mc_gross] => 20.00 [custom] => [charset] => windows-1252 [notify_version] => 3.8 [ipn_track_id] => f93ce8bdd4382 ) My problem The first IPN with the juicy tracking_id fails, the 2nd IPN is verified, But once the IPN is verified I no longer have access to the tracking_id. My questions Why does paypal send two different IPN's Why are they different? Why isn't any of this documented on Paypal? :(

  • preg_replace only part of match

    - by Tony Vipros
    Hi, I'm using preg_replace to create urls for modrewrite based paging links. I use: $nextURL = preg_replace('%/([\d]+)/%','/'.($pageNumber+1).'/',$currentURL); which works fine, however I was wondering if there is a better way without having to include the '/' in the replacement parameter. I need to match the number as being between two / as the URLs can sometimes contain numbers other than the page part. These numbers are never only numbers however, so have /[\d]+/ stops them from getting replaced.

  • \n not working in my fwrite()

    - by brett
    Not sure what could be the problem. I'm dumping data from an array $theArray into theFile.txt, each array item on a separate line. $file = fopen("theFile.txt", "w"); foreach ($theArray as $arrayItem){ fwrite($file, $arrayItem . '\n'); } fclose($file); Problem is when I open theFile.txt, I see the \n being outputted literally. Also if I try to programmatically read the file line by line (just in case lines are there), it shows them as 1 line meaning \n are really not having their desired effect.

  • PHP4: Send XML over HTTPS/POST via cURL?

    - by starmonkey
    I wrote a class/function to send xml over https via PHP4/cURL, just wondering if this is the correct approach, or if there's a better one. Note that PHP5 is not an option at present. /** * Send XML via http(s) post * * curl --header "Content-Type: text/xml" --data "<?xml version="1.0"?>...." http://www.foo.com/ * */ function sendXmlOverPost($url, $xml) { $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); // For xml, change the content-type. curl_setopt ($ch, CURLOPT_HTTPHEADER, Array("Content-Type: text/xml")); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, $xml); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // ask for results to be returned if(CurlHelper::checkHttpsURL($url)) { curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0); } // Send to remote and return data to caller. $result = curl_exec($ch); curl_close($ch); return $result; } cheers!

  • MySQL SET and ENUM types in CakePHP framework

    - by Andrew Bashtannik
    Hi! I need to use SET and ENUM types in my CakePHP 1.3 project. I found some advices, but all them are too old (2004-2006) and full of crazy methods, like modifying cake's core files. Also, CakePHP developers said that SET and ENUM types are not supported. Example: I have SET('alpha','beta') field, and I need to use this data as checkboxes in add & edit actions. Is there any way to add normal support (Form helpers etc.) of SET and ENUM fields?

  • Email Tracking - GMail

    - by Abs
    Hello all, I am creating my own email tracking system for email marketing tracking. I have been able to determine each persons email client they are using by using the http referrer but for some reason GMAIL does not send a HTTP_REFERRER at all! So I am trying to find another way of identifying when gmail requests a transparent image from my server. I get the following headers print_r($_SERVER);: DOCUMENT_ROOT = /usr/local/apache/htdocs GATEWAY_INTERFACE = CGI/1.1 HTTP_ACCEPT = */* HTTP_ACCEPT_CHARSET = ISO-8859-1,utf-8;q=0.7,*;q=0.3 HTTP_ACCEPT_ENCODING = gzip,deflate,sdch HTTP_ACCEPT_LANGUAGE = en-GB,en-US;q=0.8,en;q=0.6 HTTP_CONNECTION = keep-alive HTTP_COOKIE = __utmz=156230011.1290976484.1.1.utmcsr=(direct)|utmccn=(direct)|utmcmd=(none); __utma=156230011.422791272.1290976484.1293034866.1293050468.7 HTTP_HOST = xx.xxx.xx.xxx HTTP_USER_AGENT = Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US) AppleWebKit/534.10 (KHTML, like Gecko) Chrome/8.0.552.237 Safari/534.10 PATH = /bin:/usr/bin QUERY_STRING = i=MTA= REDIRECT_STATUS = 200 REMOTE_ADDR = xx.xxx.xx.xxx REMOTE_PORT = 61296 REQUEST_METHOD = GET Is there anything of use in that list? Or is there something else I can do to actually get the http referrer, if not how are other ESPs managing to find whether gmail was used to view an email? Btw, I appreciate it if we can hold back on whether this is ethical or not as many ESPs do this already, I just don't want to pay for their service and I want to do it internally. Thanks all for any implementation advice. Update Just thought I would update this question and make it clearer in light of the bounty. I would like to find out when a user opens my email when sent to a GMail inbox. Assume, I have the usual transparent image tracking and the user does not block images. I would like to do this with the single request and the header details I get when the transparent image is requested.

  • Exclude rows with Doctrine ORM DQL (NOT IN)

    - by Sheriffen
    I'm building a chat application with codeigniter and doctrine. Tables: - User - User_roles - User_available Relations: ONE user have MANY roles. ONE user_available have ONE user. Users available for chatting will be in the user_available table. Problem: I need to get all users in in user_available that hasn't got role_id 7. So I need to express in DQL something like (this is not even SQL, just in words): SELECT * from user_available WHERE NOT user_available.User.Role.role_id = 7 Really stuck on this one EDIT: Guess I was unclear. The tables are already mapped and Doctrine does the INNER JOIN job for me. I'm using this code to get the admin that waited the longest but now I need the user: $admin = Doctrine_Query::create() ->select('c.id') ->from('Chat_available c') ->where('c.User.Roles.role_id = ?', 7) ->groupBy('c.id') ->orderBy('c.created_at ASC') ->fetchOne(); Now I need to get the user that waited the longest but this does NOT work $admin = Doctrine_Query::create() ->select('c.id') ->from('Chat_available c') ->where('c.User.Roles.role_id != ?', 7) ->groupBy('c.id') ->orderBy('c.created_at ASC') ->fetchOne();

  • Xpath fails if an element has a a xmlns attribute

    - by Callum Lamb
    Im trying to use xml to parse a .COLLADA file. The problem is I can't seem to use xpath() to access elements if the root tag has a xmlns attribute. For example this works: $string = <<<TEST <?xml version="1.0" encoding="utf-8"?> <COLLADA version="1.4.1"> <library_materials> <material id="Material" name="Material"> <instance_effect url="#Material-effect"/> </material> <material id="Material2" name="Material"> <instance_effect url="#Material-effect2"/> </material> </library_materials> </COLLADA> TEST; $lol = new SimpleXMLElement($string); print_r($lol->library_materials->xpath("material[@id='Material2']")); But this doesn't: $string = <<<TEST <?xml version="1.0" encoding="utf-8"?> <COLLADA xmlns="http://www.collada.org/2005/11/COLLADASchema" version="1.4.1"> <library_materials> <material id="Material" name="Material"> <instance_effect url="#Material-effect"/> </material> <material id="Material2" name="Material"> <instance_effect url="#Material-effect2"/> </material> </library_materials> </COLLADA> TEST; $lol = new SimpleXMLElement($string); print_r($lol->library_materials->xpath("material[@id='Material2']")); How does the xmlns suddenly make the xml tree unusable? I thought it just defined the namespace so you could tell it apart from other identical tags in other namespaces. What am I missing?

  • Ignore duplicates in regex pattern

    I have a regex pattern that searches for words in a text file. How do I ignore duplicates? For instance, take a look at this code $pattern = '/(lorem|ipsum|daboom|pahwal|ababaga)/i'; $num_found = preg_match_all( $pattern, $string, $matches ); echo "$num_found match(es) found!"; echo "Matched words: " . implode( ',', $matches[0] ); If I have more than one say lorem in the article, the output will be something like this 5 matches found! Matched words: daboom,lorem,lorem,lorem,lorem I want the pattern to only find the first occurrence, and ignore the rest, so the output should be: 2 matches found! Matched words: daboom,lorem
