  • Setting up DomainKeys/DKIM in a PHP-based SMTP client

    - by Alex
    It looks like there are some great libraries out there to do DomainKeys signing of emails on C#/.NET, but I'm having a really hard time finding the same kind of support for PHP. Maybe I'm not looking in the right place? The only one I found is http://php-dkim.sourceforge.net/; it looks incredibly hacky and supports PHP4 only. Considering how popular PHP is, and how critical DomainKeys are for email classification as non-spam, I'd expect better tools; do you know of any? Any other tricks you'd recommend?

  • showing errors from actions in table-based views

    - by enashnash
    I have a view where I want to perform different actions on the items in each row in a table, similar to this (in, say, ~/Views/Thing/Manage.aspx): <table> <% foreach (thing in Model) { %> <tr> <td><%: thing.x %></td> <td> <% using (Html.BeginForm("SetEnabled", "Thing")) { %> <%: Html.Hidden("x", thing.x) %> <%: Html.Hidden("enable", !thing.Enabled) %> <input type="submit" value="<%: thing.Enabled ? "Disable" : "Enable" %>" /> <% } %> </td> <!-- more tds with similar action forms here, a few per table row --> </tr> <% } %> In my ThingController, I have functions similar to the following: public ActionResult Manage() { return View(ThingService.GetThings()); } [HttpPost] public ActionResult SetEnabled(string x, bool enable) { try { ThingService.SetEnabled(x, enable); } catch (Exception ex) { ModelState.AddModelError("", ex.Message); // I know this is wrong... } return RedirectToAction("Manage"); } In the most part, this is working fine. The problem is that if ThingService.SetEnabled throws an error, I want to be able to display the error at the top of the table. I've tried a few things with Html.ValidationSummary() in the page but I can't get it to work. Note that I don't want to send the user to a separate page to do this, and I'm trying to do it without using any javascript. Am I going about displaying my table in the best way? How do I get the errors displayed in the way I want them to? I will end up with perhaps 40 small forms on the page. This approach comes largely from this article, but it doesn't handle the errors in the way I need to. Any takers?

  • WP plugin based on useragent

    - by jake
    I am writing a plugin which does some js stuff, but does not work for other browsers than FF . I've thought why not execute the plugin for the browsers which support it. I've added the code, but for some reason when I activate the plugin and check the site with a FF all I get is blank page. If I visit with a IE the site is shown correctly. Basically my code is like this $agent= strtolower($_SERVER['HTTP_USER_AGENT']); if (preg_match('/firefox/',$agent)){ include(plugins_url('script.js',FILE)); some more code } So when I visit with FF I get blank page, when I visit with IE the blog loads normally

  • Custom iterator for a class based on two sets

    - by Dan Hook
    I have a class that contains two sets. They both contain the same key type but have different compare operations. I would like to provide an iterator for the class that iterates through the elements of both sets. I want to start with one set, then when I increment an iterator pointing to the last element of the first set, I want to go to the first element of the second set. How do I do this? I would like to preserve the bidirectional iterator semantics of std::set, but if it turns out that implementing a forward iterator is much easier, so be it. I'm willing to use the Boost Iterator library if that would help.

  • Calculate order price by date selection value

    - by albatross
    Alright, I know there's a simple way to do this, but it's been years since I've done much javascript My client has an online order form for event registration (developed by previous web dev.). Currently the order total is just a hidden field: <INPUT value=78.00 type=hidden name=amount /> But I need the total to calculate based on what date they choose: <SELECT style="BACKGROUND-COLOR: #ffff99" name=altDate1> <OPTION value=04/09> Friday, April 9 </OPTION> <OPTION value=04/14> Wednesday, April 14 </OPTION> <OPTION value=04/16> Friday, April 16 </OPTION> <OPTION value=04/19> Monday, April 19 </OPTION> <OPTION value=04/29> Thursday, April 29 </OPTION> </SELECT> This is the javascript that process the form: <SCRIPT language=Javascript> function PaymentButtonClick() { document.addform.Product_Name.value = document.Information.StudentLastName.value + ","+ document.Information.StudentFirstName.value+","+ document.Information.StudentID.value+","+ document.Information.altDate1.name+","+","+ document.Information.Guests.value+ "," + document.Information.StudentType.value; document.addform.Product_Code.value = document.Information.StudentID.value; if ((document.Information.UCheck.checked==true) && (document.Information.altDate1.value != "") && (document.Information.altDate1.value != "x")) { if (document.Information.StudentLastName.value != "" || document.Information.StudentFirstName.value != "" || document.Information.StudentID.value != "" ) { document.addform.submit(); } else { alert("Please enter missing information"); } } } </SCRIPT>

  • mySQL removes first digit

    - by kielie
    Hi guys, I am inputting data into a mySQL database via a PHP script, but for some reason when I check the database, all of the phone numbers have their first digit removed, like so, 0123456789 shows up as 123456789 in the database, but if I change the data type from INT to TEXT, it shows correctly, I am very hesitant to keep it as TEXT though, as I am sure this will cause complications further down the road as the database app starts to become more complicated, here is the PHP code. <?php $gender = $_POST['gender']; $first_name = $_POST['first_name']; $second_name = $_POST['second_name']; $id_number = $_POST['id_number']; $home_number = $_POST['home_number']; $cell_work = $_POST['cell_work']; $email_address = $_POST['email_address']; $curDate = date("Y-m-d"); mysql_connect ("server", "user", "pass") or die ('Error: ' . mysql_error()); mysql_select_db ("database"); $query = "INSERT INTO table (id,gender,first_name,second_name,id_number,home_number,cell_work,email_address,date) VALUES('NULL','".$gender."','".$first_name."','".$second_name."','".$id_number."','".$home_number."','".$cell_work."','".$email_address."','".$curDate."' )"; mysql_query($query) or die (mysql_error()); ?> Thanx in advance!

  • Restoring database with SMO - Reporting progress problems

    - by madlan
    I'm using the below to restore a database in VB.NET. This works but causes the interface to lockup if the user clicks anything.

  • zabbix monitoring mysql database

    - by krisdigitx
    I have a server running multiple instances of mysql and also has the zabbix-agent running. In zabbix_agentd.conf i have specified: UserParameter=multi.mysql[*],mysqladmin --socket=$1 -uzabbixagent extended-status 2>/dev/null | awk '/ $3 /{print $$4}' where $1 is the socket instance. From the zabbix server i can run the test successfully. zabbix_get -s ip_of_server -k multi.mysql[/var/lib/mysql/mysql2.sock] and it returns all the values However the zabbix item/trigger does not generate the graphs, I have created a MACRO for $1 which is the socket location {$MYSQL_SOCKET1} = '/var/lib/mysql/mysql2.sock' and i use this key in items to poll the value multi.mysql[{$MYSQL_SOCKET1},Bytes_sent] LOGS: this is what i get on the logs: 3360:20120214:144716.278 item [multi.mysql['/var/lib/mysql/mysql2.sock',Bytes_received]] error: Special characters '\'"`*?[]{}~$!&;()<>|#@' are not allowed in the parameters 3360:20120214:144716.372 item [multi.mysql['/var/lib/mysql/mysql2.sock',Bytes_sent]] error: Special characters '\'"`*?[]{}~$!&;()<>|#@' are not allowed in the parameters Any ideas where the problem could be?

  • Best practice for assigning A/B test variation based on IP address

    - by mojones
    I am starting to write some code for A/B testing in a Grails web application. I want to ensure that requests from the same IP address always see the same variation. Rather than store a map of IP-variant, is it OK to simply turn the IP address into an integer by removing the dots, then use that as the seed for a random number generator? The following is taking place in a Grails Filter: def ip = request.remoteAddr def random = new Random(ip.replaceAll(/\./, '').toInteger()) def value = random.nextBoolean() session.assignment = value // value should always be the same for a given IP address I know that identifying users by IP address is not reliable, and I will be using session variables/cookies as well, but this seems to be useful for the case where we have a new session, and no cookies set (or the user has cookies disabled).

  • Slow performance of MySQL database on one server and fast on another one, with similar configurations

    - by Alon_A
    We have a web application that run on two servers of GoDaddy. We experince slow preformance on our production server, although it has stronger hardware then the testing one, and it is dedicated. I'll start with the configurations. Testing: CentOS Linux 5.8, Linux 2.6.18-028stab101.1 on i686 Intel(R) Xeon(R) CPU L5609 @ 1.87GHz, 8 cores 60 GB total, 6.03 GB used Apache/2.2.3 (CentOS) MySQL 5.5.21-log PHP Version 5.3.15 Production: CentOS Linux 6.2, Linux 2.6.18-028stab101.1 on x86_64 Intel(R) Xeon(R) CPU L5410 @ 2.33GHz, 8 cores 120 GB total, 2.12 GB used Apache/2.2.15 (CentOS) MySQL 5.5.27-log - MySQL Community Server (GPL) by Remi PHP Version 5.3.15 We are running the same code on both servers. The Problem We have some function that executes ~30000 PDO-exec commands. On our testing server it takes about 1.5-2 minutes to complete and our production server it can take more then 15 minutes to complete. As you can see here, from qcachegrind: Researching the problem, we've checked the live graphs on phpMyAdmin and discovered that the MySQL server on our testing server was preforming at steady level of 1000 execution statements per 2 seconds, while the slow production MySQL server was only 250 executions statements per 2 seconds and not steady at all, jumping from 0 to 250 every seconds. You can clearly see it in the graphs: Testing server: Production server: You can see here the comparison between both of the configuration of the MySQL servers.Left is the fast testing and right is the slow production. The differences are highlighted, but I cant find anything that can cause such a behavior difference, as the configs are mostly the same. Maybe you can see something that I cant see. Note that our tables are all InnoDB, so the MyISAM difference is (probably) not relevant. Maybe it is the MySQL Community Server (GPL) that is installed on the production server that can cause the slow performance? Or maybe it needs to be configured differently for 64bit ? I'm currently out of ideas...

  • product suggestion based on user data

    - by Enkay
    I'm trying to add suggestions to product pages along the lines of : "Customers who purchased this item also purchased x and y". The way the data is compiled right now is a mysql table with 3 rows. PRODUCT | CUSTOMER |QUANTITY Product is the product ID. Customer is the customer ID. Quantity is the number of time that product was bought by that customer. For each product description page, the system needs to figure out which users bought that product, what other products those users bought, in what quantity and then return the 2 products that were bought the most by people who bought the current product. Hopefully this makes sense and someone can point me in the right directions as to what the mysql query should look like. Thanks.

  • Using the ASP.NET membership provider database with your own database?

    - by Shaharyar
    Hello everybody, We are developing an ASP.NET MVC Application that currently uses it's own databse ApplicationData for the domain models and another one Membership for the user management / membership provider. We do access restrictions using data-annotations in our controllers. [Authorize(Roles = "administrators, managers")] This worked great for simple use cases. As we are scaling our application our customer wants to restrict specific users to access specific areas of our ApplicationData database. Each of our products contains a foreign key referring to the region the product was assembled in. A user story would be: Users in the role NewYorkManagers should only be able to edit / see products that are assembled in New York. We created a placeholder table UserRightsRegions that contains the UserId and the RegionId. How can I link both the ApplicationData and the Membership databases in order to work properly / having cross-database-key-references? (Is something like this even possible?) All help is more than appreciated!

  • SQL Server: position based on marks

    - by Rhys
    I am using SQL Server 2008. I have a Student table in which there are following fields: 1. StudentId, 2. StudentName, 3. Marks . I want to get a resultset in which there should be a column named “Position”. Something like “Select StudentId,StudentName,Marks, as Position from Student...” so that, depending on the marks a student scored, i can evaluate them as the 1st, 2nd or 20th position. If students have the same marks, then they have the same position. Thanks. Rhys

    Hi, again I have Java AST which is created from public class Test { String o = new String("hh"); public void wrong1() { synchronized(o) { // huhu } } } I try to create a XPath query which finds the synchronized block in which the defined String variable o is used. As the definition is above it is an ancestor of the SynchronizedStatement, but I dont get it working //SynchronizedStatement[Expression/PrimaryExpression/PrimaryPrefix/Name[@Image=ancestor::ClassOrInterfaceBody[ClassOrInterfaceBodyDeclaration/FieldVariableDeclaratorId/@Image]]] I know that /SynchronizedStatement[Expression/PrimaryExpression/PrimaryPrefix/Name[@Image= is correct, my problem is how to address the ancestor ClassOrInterfaceBody part. Hope its clear what i mean ;-) Thanks

  • a better way to initialize database ONCE when rail server starts

    - by Hadi
    i would like to initialize database the first time the server is started, that involve calling a class method. Given the class name is: Product At first i put an .rb file config\initializers\init.rb as it gets automatically called. Everything works ok, until the database is deleted, and i am trying to do rake db:migrate. rake db:migrate fails saying that cannot find 'product' table. inside init.rb = Product.populate_db The solution i came up is: I took out init.rb do rake db:migrate put back init.rb run the server. My rails application is mainly for reporting and the data is seeded from other application, so i have to do the above step everyday Is there a better way to do the initialization?

  • ProductListing based on Attribute in Magento

    - by Keenora Fluffball
    I would like to show "Suggestions" in my product listing in Magento. I made an attribute "Suggestion" which is Yes/No and global active. Now in the listing I would like to show the suggestions first, then some text and stuff, and then the rest of products. I tried it like this: $_productCollection=$this->getLoadedProductCollection() /* .... */ $_productCollection->clear()->addAttributeToFilter('suggestion', 1)->load(); But this ends in an exception: You cannot define a correlation name '_price_rule' more than once Now the question is, how to solve this?

  • create table based on a user defined type

    - by Glen
    Suppose I have a user defined type: CREATE OR REPLACE TYPE TEST_TYPE AS OBJECT ( f1 varchar2(10), f2 number(5) ); Now, I want to create a table to hold these types. I can do the following: create table test_type_table ( test_type_field test_type ); This gives me a table with one column, test_type_field. Is there an easy and automated way to instead create a table such that it has 2 columns, f1 and f2?. So that it's the equivilent to writing: create table test_type_table ( f1 varchar2(10), f2 number(5) );

  • difficulty based time estimation software

    - by Frankie
    Some months ago I found a project-management / time-estimation software that would ask you to sort out your tasks in terms of difficulty (1, 2 or 3) and would then estimate the time you would take to deploy. The system would auto-adapt as you were working. I've forgot the software name. For the past days I've been digging emails and searching Google with no results. Can anyone pin the software name by my description? Its not http://www.fogcreek.com (though I've found it to be a great piece of software. Thank you in advance.

  • File system to choose for NAS box based on FreeNAS or OpenFiler [closed]

    - by Chris
    I'm a photographer and I have a requirement find a better method of storing my photos other than multiple USB2 drives via USB hubs. Currently I use a Macbook Pro and 6 external drives connected via USB2 or FW800. 3 are a copy of the first three, kept up to day manually by running an rsync backup. I'd like to run a FreeNAS or OpenFiler NAS box using 2TB drives mirrored via software RAID. But - I would like to have the flexibility of also plugging into the drive physically for the faster throughput when necessary. So. My question is, is there a file system that both *nix and Mac OSX will play nice with? Many thanks, Chris.

  • Caching view-port based Geo-queries

    - by friism
    I have a web app with a giant Google Map in it. As users pan and zoom around on the map, points are dynamically loaded through AJAX call which include the viewport bounds (NE and SW corner coordinates) and some other assorted parameters. How do I cache these request for points? The problem is that the parameters are highly variable and (worst) not discrete i.e. floats with a lots of decimal places. I'm using ASP.NET-MVC/C#/LINQ2SQL/SQL-Server but the problem is not tied to that platform. This is the signature of the the relevant method: [AcceptVerbs(HttpVerbs.Post)] public JsonResult Data(string date, string categories, string ne_lat, string ne_lng, string sw_lat, string sw_lng)

  • WCF REST based services authentication schemes

    - by FlySwat
    I have a simple authentication scheme for a set of semi-public REST API's we are building: /-----------------------\ | Client POST's ID/Pass | | to an Auth Service | \-----------------------/ [Client] ------------POST----------------------> [Service/Authenticate] | /-------------------------------\ | Service checks credentials | [Client] <---------Session Cookie------- | and generates a session token | | | in a cookie. | | \-------------------------------/ | [Client] -----------GET /w Cookie -------------> [Service/Something] | /----------------------------------\ | Client must pass session cookie | | with each API request | | or will get a 401. | \----------------------------------/ This works well, because the client never needs to do anything except receive a cookie, and then pass it along. For browser applications, this happens automatically by the browser, for non browser applications, it is pretty trivial to save the cookie and send it with each request. However, I have not figured out a good approach for doing the initial handshake from browser applications. For example, if this is all happening using a AJAX technique, what prevents the user from being able to access the ID/Pass the client is using to handshake with the service? It seem's like this is the only stumbling block to this approach and I'm stumped.
