  • Open page in Joomla

    - by dutt
    I'm using Jumi to echo php code and then showing that in a Joomla Article, and everythings working fine. Now I want to do this: The output is basically a list from a database like this: Name Price Type A 1 T1 B 2 T2 In this list I want to include links to only show items of the same type, so "T1" would like to a page only showing things of type T1. So I thought I would do this by making a new page that takes a type and then get all the items of that type from the database. Without Joomla this wouldv'e been a piece of cake, with Joomla I'm not quite sure where to begin. How should the a href=... tags in the html code printed by my php script look? Is my basic structure still correct, and if so, how do I make Joomla open the new page in the normal frame and not replace the whole Joomla page. some kind of target-frame attribute?

    I have 3 Tables in my DataBase CmsMasterPages CmsMasterPagesAdvSlots (Pure Juction Table) CmsAdvSlots Here a Picture of my EDM: I need find out all objects CmsAdvSlot connected with a CmsMasterPage (it is working in my code posted belove), and DELETE the result (CmsAdvSlot) from the DataBase. My Problem is I am not able to DELETE this Objects when I found theme. Error: The object cannot be deleted because it was not found in the ObjectStateManager. int findMasterPageId = Convert.ToInt32(uxMasterPagesListSelector.SelectedValue); CmsMasterPage myMasterPage = context.CmsMasterPages.FirstOrDefault(x => x.MasterPageId == findMasterPageId); var resultAdvSlots = myMasterPage.CmsAdvSlots; // It is working until here foreach (var toDeleteAdv in resultAdvSlots) { context.DeleteObject(myMasterPage.CmsAdvSlots.Any()); // ERORR HERE!! context.SaveChanges(); } Any idea how to solve it?

  • Insert Registration Data in MySQL using PHP

    - by J M 4
    I may not be asking this in the best way possible but i will try my hardest. Thank you ahead of time for your help: I am creating an enrollment website which allows an individual OR manager to enroll for medical testing services for professional athletes. I will NOT be using the site as a query DB which anybody can view information stored within the database. The information is instead simply stored, and passed along in a CSV format to our network provider so they can use as needed after the fact. There are two possible scenarios: Scenario 1 - Individual Enrollment If an individual athlete chooses to enroll him/herself, they enter their personal information, submit their payment information (credit/bank account) for processing, and their information is stored in an online database as Athlete1. Scenario 2 - Manager Enrollment If a manager chooses to enroll several athletes he manages/ promotes for, he enters his personal information, then enters the personal information for each athlete he wishes to pay for (name, address, ssn, dob, etc), then submits payment information for ALL athletes he is enrolling. This number can range from 1 single athlete, up to 20 athletes per single enrollment (he can return and complete a follow up enrollment for additional athletes). Initially, I was building the database to house ALL information regardless of enrollment type in a single table which housed over 400 columns (think 20 athletes with over 10 fields per athlete such as name, dob, ssn, etc). Now that I think about it more, I believe create multiple tables (manager(s), athlete(s)) may be a better idea here but still not quite sure how to go about it for the following very important reasons: Issue 1 If I list the manager as the parent table, I am afraid the individual enrolling athlete will not show up in the primary table and will not be included in the overall registration file which needs to be sent on to the network providers. Issue 2 All athletes being enrolled by a manager are being stored in SESSION as F1FirstName, F2FirstName where F1 and F2 relate to the id of the fighter. I am not sure technically speaking how to store multiple pieces of information within the same table under separate rows using PHP. For example, all athleteswill have a first name. The very basic theory of what i am trying to do is: If number_of_athletes 1, store F1FirstName in row 1, column 1 of Table "Athletes"; store F1LastName in row 1, column 2 of Table "Athletes"; store F2FirstName in row 2, column 1 of Table "Athletes"; store F2LastName in row 2, column 2 of table "Athletes"; Does this make sense? I know this question is very long and probably difficult so i appreciate the guidance.

  • array insert in db

    - by gloris
    Hi, How best to put the array (100 or more length) in the database (MySQL)? I do not want multiple access to the database because it is so loaded. So my solution is as follows: string insert = "INSERT INTO programs (name, id) VALUES "; for(int i = 0; i < name.Length; i++) { if (i != 0) { insert = insert + ",("; } else { insert = insert + "("; } insert = insert + "'" + name[i] + "','" + id[i] + "'"; insert = insert + ")"; } //INSERT INTO programs (name, id) VALUES ('Peter','32'),('Rikko','343') .... But maybe is a faster version? Thanks

  • What's the difference between /123 and /?123?

    - by BoltClock
    I've noticed that some sites (including http://jobs.stackoverflow.com) have query strings that look like this: http://somewebapp.example/?123 as compared to: http://somewebapp.example/123 or http://somewebapp.example/id/123 What are the reasons that developers choose to implement their web apps' URLs using the first example instead of the second and third examples? And as a bonus, how would one implement the first example in PHP, given that 123 is the primary key of some row in a database table? (I just need to know how to retrieve 123 from the URL; I already know how to query the database for a primary key of 123.)

  • How should I configure backup of my server?

    - by ed209
    I have just rented a dedicated server. If it helps this is the config I have: CPU1 Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz (Cores 8) RAM 15975 MB Disk /dev/sda doesn't contain a valid partition table (=> /dev/sda doesn't) Disk /dev/sdc doesn't contain a valid partition table (=> /dev/sdc doesn't) Disk /dev/sdb doesn't contain a valid partition table (=> /dev/sdb doesn't) Disk /dev/sda: 120.0 GB (=> 114 GIB) Disk /dev/sdc: 3000.6 GB (=> 2861 GIB) Disk /dev/sdb: 3000.6 GB (=> 2861 GIB) /dev/sda is a 120GB SSD. This is where I have Ubuntu/lamp installed. It's the drive that will run my site. With the account I got two other drives of 3000GB each which I really don't need but they came with the account. I figured I could use these to back up my main 120gb drive. So a couple of things I wondered were: Should I use these for backups? How should I back up. The data I want to back up is a user uploads directory full of images and the database. Everything else is either in a code repo or backed up some other way. For example, it would be nice to know there is a disk image of the 120gb drive somewhere that I can copy over should there be any problems but equally I don't mind doing a fresh install of all the software and copying over just the images and database dump. Thanks for your advice! (also, happy to not use the two other drives and backup elsewhere if it's more sensible)

  • Retain ViewData when editing variable length list

    - by Pieter
    I'm editing variable length lists and use ViewData to pass around information for filling a DropDownList. I use the method described here for editing these lists: http://blog.stevensanderson.com/2010/01/28/editing-a-variable-length-list-aspnet-mvc-2-style/ The data for this dropdownlist comes from the database. As the ViewData is not available across requests, I currently do a new query to the database each and every time. This also happens when the ModelState is not valid and the form is redisplayed. Of course, this is less then ideal even for a light-weight query as this one. How can I retain the information from that query across requests as long as the user is editing the page with that variable length list?

  • MySQL Prepared Statements vs Stored Procedures Performance

    - by amardilo
    Hi there, I have an old MySQL 4.1 database with a table that has a few millions rows and an old Java application that connects to this database and returns several thousand rows from this this table on a frequent basis via a simple SQL query (i.e. SELECT * FROM people WHERE first_name = 'Bob'. I think the Java application uses client side prepared statements but was looking at switching this to the server, and in the example mentioned the value for first_name will vary depending on what the user enters). I would like to speed up performance on the select query and was wondering if I should switch to Prepared Statements or Stored Procedures. Is there a general rule of thumb of what is quicker/less resource intensive (or if a combination of both is better)

  • I want to retrieve some information based on Caller ID

    - by Hassan Al-Jeshi
    Hello, my friend has a Real Estate company that receives a lot of phone calls everyday. He wants to have a solution such that when somebody call to his company, the operator sees all the information about the person who is calling based on the database he have right now and the caller ID. Is there a ready made software or solution that can do the job?? Since I'm a software engineer myself, I would never mind developing something from scratch or built on a ready made system (with a team of course), but I need some direction on how to start?? Notes: 1- cost is not an issue 2- the customers database is there but we never mind replacing it in a format to suit the new solution Best Regards,

  • How to write custom SQLite functions in Javascript inside a Webkit browser?

    - by Jay Godse
    I have just learned how to use the SQLite database for local storage in a Webkit web browser (e.g. Google Chrome or Apple Safari) using the Javascript API. For example the "Sticky Notes" application. However, I know that SQLite has a function called sqlite_create_function() that lets you add custom functions to your instance of SQLite on the fly which can then be used inside SQL queries. This function is described at sqlite.org. I also know that you can call an equivalent of this API in Ruby as described here. QUESTION: Can anybody show me how to do this in Javascript - i.e. write a custom function in Javascript that can be bound into the SQLite database at run time to be called by the SQLite engine, and all inside a Webkit browser?

  • Many-to-one relation exception due to closed session after loading

    - by Nick Thissen
    Hi, I am using NHibernate (version 1.2.1) for the first time so I wrote a simple test application (an ASP.NET project) that uses it. In my database I have two tables: Persons and Categories. Each person gets one category, seems easy enough. | Persons | | Categories | |--------------| |--------------| | Id (PK) | | Id (PK) | | Firstname | | CategoryName | | Lastname | | CreatedTime | | CategoryId | | UpdatedTime | | CreatedTime | | Deleted | | UpdatedTime | | Deleted | The Id, CreatedTime, UpdatedTime and Deleted attributes are a convention I use in all my tables, so I have tried to bring this fact into an additional abstraction layer. I have a project DatabaseFramework which has three important classes: Entity: an abstract class that defines these four properties. All 'entity objects' (in this case Person and Category) must inherit Entity. IEntityManager: a generic interface (type parameter as Entity) that defines methods like Load, Insert, Update, etc. NHibernateEntityManager: an implementation of this interface using NHibernate to do the loading, saving, etc. Now, the Person and Category classes are straightforward, they just define the attributes of the tables of course (keeping in mind that four of them are in the base Entity class). Since the Persons table is related to the Categories table via the CategoryId attribute, the Person class has a Category property that holds the related category. However, in my webpage, I will also need the name of this category (CategoryName), for databinding purposes for example. So I created an additional property CategoryName that returns the CategoryName property of the current Category property, or an empty string if the Category is null: Namespace Database Public Class Person Inherits DatabaseFramework.Entity Public Overridable Property Firstname As String Public Overridable Property Lastname As String Public Overridable Property Category As Category Public Overridable ReadOnly Property CategoryName As String Get Return If(Me.Category Is Nothing, _ String.Empty, _ Me.Category.CategoryName) End Get End Property End Class End Namespace I am mapping the Person class using this mapping file. The many-to-one relation was suggested by Yads in another thread: <id name="Id" column="Id" type="int" unsaved-value="0"> <generator class="identity" /> </id> <property name="CreatedTime" type="DateTime" not-null="true" /> <property name="UpdatedTime" type="DateTime" not-null="true" /> <property name="Deleted" type="Boolean" not-null="true" /> <property name="Firstname" type="String" /> <property name="Lastname" type="String" /> <many-to-one name="Category" column="CategoryId" class="NHibernateWebTest.Database.Category, NHibernateWebTest" /> (I can't get it to show the root node, this forum hides it, I don't know how to escape the html-like tags...) The final important detail is the Load method of the NHibernateEntityManager implementation. (This is in C# as it's in a different project, sorry about that). I simply open a new ISession (ISessionFactory.OpenSession) in the GetSession method and then use that to fill an EntityCollection(Of TEntity) which is just a collection inheriting System.Collections.ObjectModel.Collection(Of T). public virtual EntityCollection< TEntity Load() { using (ISession session = this.GetSession()) { var entities = session .CreateCriteria(typeof (TEntity)) .Add(Expression.Eq("Deleted", false)) .List< TEntity (); return new EntityCollection< TEntity (entities); } } (Again, I can't get it to format the code correctly, it hides the generic type parameters, probably because it reads the angled symbols as a HTML tag..? If you know how to let me do that, let me know!) Now, the idea of this Load method is that I get a fully functional collection of Persons, all their properties set to the correct values (including the Category property, and thus, the CategoryName property should return the correct name). However, it seems that is not the case. When I try to data-bind the result of this Load method to a GridView in ASP.NET, it tells me this: Property accessor 'CategoryName' on object 'NHibernateWebTest.Database.Person' threw the following exception:'Could not initialize proxy - the owning Session was closed.' The exception occurs on the DataBind method call here: public virtual void LoadGrid() { if (this.Grid == null) return; this.Grid.DataSource = this.Manager.Load(); this.Grid.DataBind(); } Well, of course the session is closed, I closed it via the using block. Isn't that the correct approach, should I keep the session open? And for how long? Can I close it after the DataBind method has been run? In each case, I'd really like my Load method to just return a functional collection of items. It seems to me that it is now only getting the Category when it is required (eg, when the GridView wants to read the CategoryName, which wants to read the Category property), but at that time the session is closed. Is that reasoning correct? How do I stop this behavior? Or shouldn't I? And what should I do otherwise? Thanks!

  • WebService Security

    - by LauzPT
    Hello, I'm developing an project, which consists in a webservice and a client application. It's a fair simple scenario. The webservice is connected to a database server, and the client consumes from the webserver in order to get information retrieved from the database. The thing is: 1. The client application can only display data after a previous authentication; 2. All the data transferred between Web Service and clients must be confidential; 3. Data integrity shouldn’t be compromised; I'm wondering what is the best way to achieve these requirements. The first thing I thought about, was sending the server a digital signature containing a client certificate, to be stored in the server, and used as comparison for authentication. But I investigated a little about webservice security, and I'm no longer certain that this is the best option. Can anyone give me an opinion about this? TIA

  • Using multiple databases within one application (ASP.NET MVC, LINQ to SQL)

    - by Alex
    I have a web application made for several groups of people not connected with each other. Instead of using one database for all of them, I'm thinking about making separate databases. This will improve the speed of the queries and make me free from checking to what group the user belongs. But since I'm working with LINQ to SQL, my classes are explicitly connected with the databases, so I will have to make separate DataContexts for all of the databases. So how can I solve this problem? Or should I just not bother and use one database only?

  • UTF8 issues on Linux

    - by user363808
    Hi, I have some code that fetches some data from the database, database codepage is UTF8. When I run the code on a linux box, some characters come out as question marks (?) but when I run the same code on a windows server, all characters appear correctly. When I do: $ $LANG Following is returned en_SG.UTF-8 en_SG is something that doesn't look correct, it should be en_US but the latter part of the returned string is UTF-8 which is good. Is there anything else that I can look into to fix the character corruption problem?

  • How do I effectively store a connection string in machine.config only?

    - by Scott Bedwell
    We are moving to an environment with multiple engines of MS SQL running on the same server (a test engine and a production engine). We also have separate test and production web servers, and would like for our asp.net applications to "magically" use the test database engine on the test web server and the production database engine on the production web servers. We would like to store the connection strings in machine.config rather than in web.config, but when we put it in machine.config, visual studio's IDE (particularly with datasets) does not recognize that the machine.config contains the connection. Does anyone know of a solution for displaying these machine.config connection strings in visual studio, or of a different solution that would accommodate for this? Thanks.

  • How to run a COM .dll on a remote server?

    - by PrgTrdr
    I have a legacy 3rd party COM .dll that is used to provide an Excel-callable interface to a proprietary database product. The .dll runs on the same physical machine as Excel. I have a need to execute the .dll (and the database it is calling) on a remote server while still maintaining simple Excel callability from the client. I'm totally confused by all the different MS technologies that seem to hint there is an easy way to do this. Can someone please point me in the right direction (easier is better)?

  • Understanding where an amazon ec2 instance run?

    - by kenzo450D
    I am currently using the aws api from my local desktop. I can successfully take backups of my amazon volumes, and even create an ami from it. Now when i wanted to run the instance to be built from this ami, where does the instance run? In their Elastic Cloud or the computer from which the command was issued. Suppose I want to create the new instance in a new region? (locations as defined in ec2-describe-regions) How would I do that? It seems i have a bad knowledge about how the relation between amazon volumes and instances? Please explain it. I am only allowed to use the CLI tools to do all of my work. I made a new snapshot of the existing instance, made an ami using ec2-register, made a keypair, and then followed these steps, http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/launching-an-instance.html#launching-an-instance-cli but i got an error as this Client.InvalidParameterValue: The requested instance type's architecture (i386) does not match the architecture in the manifest for aki-fc37bacc (x86_64) my local computer is 32bit. But I do not want to load instance on the local computer but on amazon servers?

  • Can a MAC address be used as a reliable part of a rights management (DRM) scheme?

    - by Jarrod Mosen
    We're currently writing some software that we want to protect. We thought that registering a user's MAC address in a database upon activation of the software seemed viable; we can profile and grab that with a Java applet, (is there a better way?) so getting it isn't too much of a problem. However, we want their computer to only run the application, and download application files/updates from the server when their MAC address has been verified with their one on-file. We understand that this means a lockdown to one computer, but special changes can be made on request. What would be the best way to verify their MAC address, to see if it exists in the database, and then serve them the files to run the application? (And to simply run it on subsequent requests, to prevent re-downloading.)

  • What is the fastest way to get the persisted object after calling Hibernate's saveOrUpdate?

    - by Dave
    I'm using Hibernate 3.2.1.ga, hibernate annotations 3.2.1.ga, and hibernate-jpa-2.0-api. I can't upgrade at this time as I'm working with legacy code. I have this generic method for saving or updating objects ... protected void saveOrUpdate(Object obj) { final Session session = sessionFactory.getCurrentSession(); session.saveOrUpdate(obj); } You can assume that every argument, "obj," will have a member field that is marked with the "@Id" annotation. I would like to change the return type to return an Object that represents the persisted object in the database (meaning if "obj" didn't contain an id before, what is returned is the database object with a populated id. What is the fastest way to do this given my versioning and generic constraints?

  • Using SSIS, how do you read a datetime field into a variable that is of Data Type string?

    - by Mark Kadlec
    This one has bugged me for the longest time and a great question to ask the Stackoverflow users I think. I have a rather large SSIS flow that uses a string variable to store the datetime. I would now like to dynamically read the datetime value from the database, but how would you construct the SSIS to do this? My first obvious thought would be to simply execute a SQL task to get the datetime and store it in the variable, but got the "differs from the current variable type" error. Is there a simple way to convert the database datetime into a String variable? Any help from the community would be appreciated,
