• PHP MYSQL Insert Data in Arabic Language

  - by h_a86

  I am trying to insert some Arabic Language data into MySQL using PHP and an HTML form. When I insert the data in to MYSQL table, the table field represents data as مرحبا العالم. But when I access the same data with PHP and show it in my webpage, it shows the correct data. I am using: http-equiv="Content-Type" content="text/html; charset=utf-8" meta tag in my web page to show Arabic data. My question is why my data looks like this: مرحبا العالم in MySQL table, and how should I correct it.

• Output of Iterable.sliding as Tuple

  - by ziggystar

  The method sliding on collections returns a sliding window of given size in the form of X[Iterable[A]] with X being the type of the collection and A the element type. Often I need two or three elements and I prefer to have them named. One ugly workaround for sliding(2) is the following: points.sliding(2).foreach{ twoPoints => val (p1,p2) = (twoPoints.head,twoPoints.last) //do something } This sucks and only works for two elements. Also note that (a,b) = (twoPoints(0),twoPoints(1)) doesn't work. Help me!

• JQuery .get() only passing first two data parameters in url

  - by The.Anti.9

  I have a $.get() call to a PHP page that takes 4 GET parameters. For some reason, despite giving the $.get() call all 4, it only passes the first two. When I look at the dev console in chrome, it shows the URL that gets called, and it only passes action and dbname. Heres the code: $.get('util/util.php', { action: 'start', dbname: db, url: starturl, crawldepth: depth }, function(data) { if (data == 'true') { status = 1; $('#0').append(starturl + "<ul></ul>"); $('#gobutton').hide(); $('#loading').show("slow"); while(status == 1) { setTimeout("update()",10000); } } else { show_error("Form data incomplete!"); } }); and heres the URL that I see in the developer console: http://localhost/pci/util/util.php?action=start&dbname=1hkxorr9ve1kuap2.db

• Updating cached counts in MySQL

  - by phleet

  In order to fix a bug, I have to iterate over all the rows in a table, updating a cached count of children to what its real value should be. The structure of the things in the table form a tree. In rails, the following does what I want: Thing.all.each do |th| Thing.connection.update( " UPDATE #{Thing.quoted_table_name} SET children_count = #{th.children.count} WHERE id = #{th.id} " ) end Is there any way of doing this in a single MySQL query? Alternatively, is there any way of doing this in multiple queries, but in pure MySQL? I want something like UPDATE table_name SET children_count = ( SELECT COUNT(*) FROM table_name AS tbl WHERE tbl.parent_id = table_name.id ) except the above doesn't work (I understand why it doesn't).

• file_get_contents not working

  - by DCD

  I am trying to read a file in with file_get_contents () - it's a remote HTTP file, and I've checked the URL and it's fine. Only it doesn't work. More to the point the the error message is the standard Firefox server error: The connection was reset The connection to the server was reset while the page was loading. ... rather than any form of PHP error. It also only took a couple of seconds to come back so it can't be hitting the script runtime limit - any ideas on what is going wrong here? It's PHP 5 on Apache 2, running on Windows btw.

• Storing SQL Tables for use in visual studio

  - by Raven Dreamer

  Greetings. I'm trying to create a windows form application that manipulates data from several tables stored on a SQL server. 1) What's the best way to store the data locally, while the application is running? I had a previous program that only modified one table, and that was set up to use a datagridview. However, as I don't necessarily want to view all the tables, I am looking for another way to store the data retrieved by the SELECT * FROM ... query. 2) Is it better to load the tables, make changes within the C# application, and then update the modified tables at the end, or simply perform all operations on the database, remotely (retrieving the tables each time they are needed)? Thank you.

• Network license control for a Java application

  - by user1461615

  I have been tasked with providing some form of network license control for a Java application. The app would be stored on a network drive and run from a client machine. The basic idea is that it will be able to work out how many times it is being run concurrently and prevent the N+1th user from running the software where N is the number of concurrent licenses the customer has purchased. Is this possible somehow with a Java application? I implemented a "solution" which relied on multi-cast UDP communication between the running instances of the application but this didn't work because on most networks this kind of communication is blocked by security measures. Is there a better way? I don't even mind if it requires JNI/JNA. N.B. The solution does not have to be that sophisticated or highly secure.

• Empty data was able to be stored to the Database in CakePHP even if "Not Null" had been specified.

  - by kwokwai

  Hi all, I was doing some self learning on CakePHP 1.26 with Mysql 5. I got a simple table with only one field and had applied "Not Null" to this field. This field in the table was corresponding to a Input text box in a HTML form. I tried not to enter anything into the Input text field, and then I saw that empty data was able to be stored into the Table even if "Not Null" had been applied to this field. I am confused of this result. Could you help me please?

• PHP - login to a remote server, trough my own server, with HTTPS, cookies and proxy, and downloading the html

• IE7 and IE8 change event not being thrown for text input

  - by Sam

  I have a form that I auto focus at startup of the page with jquery. I also have change event handlers in place for whenever an input changes. If I change the value of the first field that was autofocused, and then move to the next field, the change event handler doesn't fire. If I remove the autofocusing, and just focus manually, then change it then move to the next field, the change event does fire. This only happens on IE. It works fine on firefox and chrome. Anyone experience this before?

• Using a database with C#

  - by Mike

  I have been trying to do something that I think would be really easy but have never used C# before and am having trouble with the details. I simple want to use a sql database with Visual C# Express 2008. For testing purposes I have a datagrid on my form that can reflect changes to the db. If i use this: codesTableAdapter.Fill(dataSet1.codes); The datagrid(dataset) will fill with the info from the sql database. If i then do something like this: codesTableAdapter.InsertQuery(txtCode.Text,txtName.Text); codesTableAdapter.Fill(dataSet1.codes); codesTableAdapter.Update(dataSet1); dataSet1.AcceptChanges(); The datagrid reflects the changes but if close the program and go to the database the changes are not there. When I open the program again the changes are not there. I have a feeling this isn't too clear as my understanding here is very low so please let me know what other info is needed. Thanks

• How do I gather a class' css attributes given nothing but the className?

  - by user1128571

  For example I might have some css stuff that looks like this: .divType1 { position: absolute; width: 60px; height: 60px; left: 400px; top: 100px; border: 1px solid #89B; z-index: 0; } Now within Javascript I want to gather div class divType1' css attributes, but am provided only with the div class, so I can't do something of form ( pseudo-code ): selectDivWithClass( divType1 ).getCss(left). I could hack something by instantiating a div with class divType1 and grab its css attributes, and then destroy it, but is there a better way?

• How to overwrite virtual fnc in good style? [C++]

  - by atch

  Hi, guys I know this question is very basic but I've met in few publications (websites, books) different style of overwriting virtual function. What I mean is: if I have base class: class Base { public: virtual void f() = 0; }; in some publications I saw that to overwrite this some authors would just say: void f(); and some would still repeat the virtual keyword before void. Which form of overwriting is in good style? Thank you for your answers.

• Bible reference books (PHP / MySQL / Unix)

  - by Josh K

  I'm looking for some nice heavy books to liter around my desk and make it look like I'm a hard core programmer. On the occasion that I might want to look something up they will also need to be useful dependable books. I'm looking for the equivalent bible in PHP, MySQL, and Unix. Should be laid out with some chapters I can actually read, along with having an in-depth reference to that particular subject. I know that the majority of this can be found on Google, but I would prefer it in book form.

• Django model data consistency

  - by Mark

  When creating a form, you can define a bunch of methods, clean_xyz, to make sure the data gets forced into the correct format. Is there any way to do this on a model level? Perhaps I can override the field setters somehow? I want it so that if I write something like my_address.postal_code = 'a1b2c3' It will automatically get formatted into A1B 2C3. Perhaps throw an exception if it can't be converted. That way I know I'll never have any malformed data in the database.

• mysql querying age from dob

  - by Confused

  My MySQL database has date of birth stored in the format yyyy-mm-dd, how do I query the database - without using php code - to show me results of people born within x years of now, and/or, who are y years of age? The table is called users, the colum is called dob. I've spent a while viewing the MySQL manual but I can't work out precisely how to form my query. So far I went for select * from users where dob... but I don't think that's the way to go.

• How to encode content to send them via jquery to a php file?

  - by phpheini

  I am trying to send a form to a php file via jquery. The problem is, that the content, which has to be sent to the php file, contains slashes (/) since there is bb code inside. So I tried the following: $.ajax( { type: "POST", url: "create.php", data: "content=" + encodeURIComponent(content), cache: false, success: function(message) { $("#somediv").html(message); } }); In the php file I use rawurldecode to decode the content and get my bb codes back which I can then transform into html. The problem is as soon as I put the encodeURIComponent() it will ouput: [object HTMLTextAreaElement] What does that mean, where is my mistake? Thanks for your help! phpheini

• Preventing SQL injecting in a database class

  - by Josh

  I'm building a database class and thought it'd be a good idea to incorporate some form of SQL injection prevention (duh!). Here's the method that runs a database query: class DB { var $db_host = 'localhost'; var $db_user = 'root'; var $db_passwd = ''; var $db_name = 'whatever'; function query($sql) { $this->result = mysql_query($sql, $this->link); if(!$this->result) { $this->error(mysql_error()); } else { return $this->result; } } } There's more in the class than that but I'm cutting it down just for this. The problem I'm facing is if I just use mysql_real_escape_string($sql, $this->link); then it escapes the entire query and leads to a SQL syntax error. How can I dynamically find the variables that need to be escaped? I want to avoid using mysql_real_escape_string() in my main code blocks, i'd rather have it in a function. Thanks.
