  • Using array instead of lots of db queries in PHP

    - by Tural Teyyuboglu
    My function looks like that. It works but does lots of work (recursively calls itself and does lots of db queries.). There must be another way to do same thing but with array (with one query). I can't figure out how to modify this function to get it work with array. Please help. function genMenu($parent, $level, $menu, $utype) { global $db; $stmt=$db->prepare("select id, name FROM navigation WHERE parent = ? AND menu=? AND user_type=?") or die($db->error); $stmt->bind_param("iii", $parent, $menu, $utype) or die($stmt->error); $stmt->execute() or die($stmt->error); $stmt->store_result(); /* bind variables to prepared statement */ $stmt->bind_result($id, $name) or die($stmt->error); if ($level > 0 && $stmt->num_rows > 0) { echo "\n<ul>\n"; } while ($stmt->fetch()) { echo "<li>"; echo '<a href="?page=' . $id . '">' . $name . '</a>'; //display this level's children genMenu($id, $level+1, $menu, $utype); echo "</li>\n\n"; } if ($level > 0 && $stmt->num_rows > 0) { echo "</ul>\n"; } $stmt->close(); }

  • JSON to javaScript array

    - by saturn_research
    I'm having a problem handling JSON data within JavaScript, specifically in regards to using the data as an array and accessing and iterating through individual values. The JSON file is structured as follows: { "head": { "vars": [ "place" , "lat" , "long" , "page" ] } , "results": { "bindings": [ { "place": { "type": "literal" , "value": "Building A" } , "lat": { "datatype": "http://www.w3.org/2001/XMLSchema#float" , "type": "typed-literal" , "value": "10.3456" } , "long": { "datatype": "http://www.w3.org/2001/XMLSchema#float" , "type": "typed-literal" , "value": "-1.2345" } , "page": { "type": "uri" , "value": "http://www.example.com/a.html" } } , { "place": { "type": "literal" , "value": "Building B" } , "lat": { "datatype": "http://www.w3.org/2001/XMLSchema#float" , "type": "typed-literal" , "value": "11.3456" } , "long": { "datatype": "http://www.w3.org/2001/XMLSchema#float" , "type": "typed-literal" , "value": "-2.2345" } , "page": { "type": "uri" , "value": "http://www.example.com/b.html" } } , { "place": { "type": "literal" , "value": "Building C" } , "lat": { "datatype": "http://www.w3.org/2001/XMLSchema#float" , "type": "typed-literal" , "value": "12.3456" } , "long": { "datatype": "http://www.w3.org/2001/XMLSchema#float" , "type": "typed-literal" , "value": "-3.2345" } , "page": { "type": "uri" , "value": "http://www.example.com/c.html" } } ] } } I want to be able to convert this into a JavaScript array as follows in order that I can iterate through it and pull out the values for each location in order: var locations = [ ['Building A',10.3456,-1.2345,'http://www.example.com/a.html'], ['Building B',11.3456,-2.2345,'http://www.example.com/b.html'], ['Building C',12.3456,-3.2345,'http://www.example.com/c.html'] ]; Does anyone have any advice on how to achieve this? I have tried the following, but it picks up the "type" within the JSON, rather than just the value: $.each(JSONObject.results.bindings, function(i, object) { $.each(object, function(property, object) { $.each(object, function(property, value) { value; }); }); }); Any help, suggestions, advice or corrections would be greatly appreciated.

  • Storing Result set into an array

    - by OVERTONE
    i know this should be simpel and im probably staring straight at the problem but once again im stuck and need the help of the code gurus. im trying too take one row from a column in jdbc, and put them in an array. i do this as follows: public void fillContactList() { createConnection(); try { Statement stmt = conn.createStatement(); ResultSet namesList = stmt.executeQuery("SELECT name FROM Users"); try { while (namesList.next()) { contactListNames[1] = namesList.getString(1); System.out.println("" + contactListNames[1]); } } catch(SQLException q) { } conn.commit(); stmt.close(); conn.close(); } catch(SQLException e) { } creatConnection is an already defined method that does what it obviously does. i creat my result set while theres another one, i store the string of that column into an array. then print it out for good measure. too make sure its there. the problem is that its storing the entire column into contactListNames[1] i wanted to make it store column1 row 1 into [1] then column 1 row 2 into [2] i know i could do this with a loop. but i dont know too take only one row at a time from a single column. any ideas? p.s ive read the api, i jsut cant see anything that fits.

  • Declaring an array of character pointers (arg passing)

    - by Isaac Copper
    This is something that should be easy to answer, but is more difficult for me to find a particular right answer on Google or in K&R. I could totally be overlooking this, too, and if so please set me straight! The pertinent code is below: int main(){ char tokens[100][100]; char str = "This is my string"; tokenize(str, tokens); for(int i = 0; i < 100; i++){ printf("%s is a token\n", token[i]); } } void tokenize(char *str, char tokens[][]){ //do stuff with string and tokens, putting //chars into the token array like so: tokens[i][j] = <A CHAR> } So I realize that I can't have char tokens[][] in my tokenize function, but if I put in char **tokens instead, I get a compiler warning. Also, when I try to put a char into my char array with tokens[i][j] = <A CHAR>, I segfault. Where am I going wrong? (And in how many ways... and how can I fix it?) Thanks so much!

  • Find messages from certain key till certain key while being able to remove stale keys.

    - by Alfred
    My problem Let's say I add messages to some sort of datastructure: 1. "dude" 2. "where" 3. "is" 4. "my" 5. "car" Asking for messages from index[4,5] should return: "my","car". Next let's assume that after a while I would like to purge old messages because they aren't useful anymore and I want to save memory. Let's say at time x messages[1-3] became stale. I assume that it would be most efficient to just do the deletion once every x seconds. Next my datastructure should contain: 4. "my" 5. "car" My solution? I was thinking of using a concurrentskiplistset or concurrentskiplist map. Also I was thinking of deleting the old messages from inside a newSingleThreadScheduledExecutor. I would like to know how you would implement(efficiently/thread-safe) this or maybe use a library?

  • Windows Macro + Hot Key - Paste Without Formatting

    - by JasonStoltz
    Not sure if this appropriate to put as a question or not? It's sort of a scripting question I think. Just down vote me if not :p Basically, what I'm looking for is a way to push a windows hotkey and have whatever text is in the clipboard be stripped of formatting. An example of what the macro could do: I push (whatever hotkey combo here) open notepad.exe Paste to notepad from clipboard Select all text in notepad Copy/Cut all text from notepad Close notepad I'm just wondering if someone has done something like this before, or knows how it could be accomplished. I think this could be a huge time-saver for almost anyone. I find myself doing this all the time when cutting and pasting between different office applications, etc.

  • Ruby - Nokogiri - Need to put node.value to an array

    - by r3nrut
    What I'm trying to do is read the value for all the nodes in this XML and put them into an array. This should be simple but for some reason it's driving me nuts.

  • Hibernate Many-To-One Foreign Key Default 0

    - by user573648
    I have a table where the the parent object has an optional many-to-one relationship. The problem is that the table is setup to default the fkey column to 0. When selecting, using fetch="join", etc-- the default of 0 on the fkey is being used to try over and over to select from another table for the ID 0. Of course this doesn't exist, but how can I tell Hibernate to treat a value of 0 to be the same as NULL-- to not cycle through 20+ times in fetching a relationship which doesn't exist? <many-to-one name="device" lazy="false" class="Device" not-null="true" access="field" cascade="none" not-found="ignore"> <column name="DEVICEID" default="0" not-null="false"/>

  • Entity Framework EntityKey / Foreign Key problem.

    - by Ronny176
    Hi, I keep getting the same error: Entities in 'VlaamseOverheidMeterEntities.ObjectMeter' participate in the 'FK_ObjectMeter_Meter' relationship. 0 related 'Meter' were found. 1 'Meter' is expected. I have the following table structure: Meter 1 <- * ObjectMeter * - 1 VO_Object It is always the same scenario: The first meter is added to the database, the second meter gives the error above. I have the following code in my manager: public List<string> addTemporary(string username, string meterNaam, string readingType, string parentID) { Meter meter = new Meter(); VO_Object voObject = objectManager.getObjectByID(parentID); ObjectMeter objMeter = new ObjectMeter(); meter.readingType = (int)Enum.Parse(typeof(ReadingType), readingType); meter.isActive = true; meter.name = meterNaam; meter.startDate = DateTime.Now; meter.endDate = DateTime.Now.AddYears(6000); meter.uniqueIdentifier = "N/A"; meter.meterType = (int)Enum.Parse(typeof(MeterType), "NA"); meter.meterCategory = (int)Enum.Parse(typeof(MeterCategory), "NA"); meter.energyType = (int)Enum.Parse(typeof(EnergyType), "NA"); meter.utilityType = (int)Enum.Parse(typeof(UtilityType), "NA"); meter.unitOfMeasure = (int)Enum.Parse(typeof(UnitOfMeasure), "NA"); objMeter.valid_from = meter.startDate; objMeter.valid_until = meter.endDate; objMeter.Meter = meter; objMeter.VO_Object = voObject; createMeter(meter); List<String> str = new List<string>(); str.Add("" + meter.meterID); str.Add(meter.name); return str; } and this in my Dao Class which links to the database: internal void CreateMeter(Meter _meter) { _entities.AddToMeter(_meter); _entities.SaveChanges(); } Can someone please explain this error?

  • "2d Search" in Solr or how to get the best item of the multivalued field 'items'?

    - by Karussell
    The title is a bit awkward but I couldn't found a better one. My problem is as follows: I have several users stored as documents and I am storing several key-value-pairs or items (which have an id) for each document. Now, if I apply highlighting I can get the first n items. If you have several hundreds of such items this highlighting is necessary and works nicely. But there are two problems: The highlighted text won't contain the id and so retrieving additional information of the highlighted item text is ugly. E.g. you need to store the id in the text so that the highlighter returns it. Adding the id to the hl.fl parameter does not help. You will not get the most relevant n-items. You will get the first n items ... So how can I find the best items of a documents with multiple such items? I will now add my own findings as answers, but as I will point out. Each of them has its drawbacks. Hopefully anyone of you can point me to a better solution.

  • A better way of getting a data table with various column types into string array

    - by Vlad
    This should be an easy one, looks like I got myself too confused. I get a table from a database, data ranges from varchar to int to Null values. Cheap and dirty way of converting this into a tab-delimited file that I already have is this (shrunken to preserve space, ugliness is kept on par with original): da.Fill(dt) ' da - DataAdapter ' ' dt - DataTable ' Dim lColumns As Long = dt.Columns.Count Dim arrColumns(dt.Columns.Count) As String Dim arrData(dt.Columns.Count) As Object Dim j As Long = 0 Dim arrData(dt.Columns.Count) As Object For i = 0 To dt.Rows.Count - 1 arrData = dt.Rows(i).ItemArray() For j = 0 To arrData.GetUpperBound(0) - 1 arrColumns(j) = arrData(j).ToString Next wrtOutput.WriteLine(String.Join(strFieldDelimiter, arrColumns)) Array.Clear(arrColumns, 0, arrColumns.GetLength(0)) Array.Clear(arrData, 0, arrData.GetLength(0)) Next Not only this is ugly and inefficient, it is also getting on my nerves. Besides, I want, if possible, to avoid the infamous double-loop through the table. I would really appreciate a clean and safe way of rewriting this piece. I like the approach that is used here - especially that is trying to solve the same problem that I have, but it crashes on me when I apply it to my case directly.

  • SQL return ORDER BY result as an array

    - by EarthMind
    Is it possible to return groups as an associative array? I'd like to know if a pure SQL solution is possible. Note that I release that I could be making things more complex unnecessarily but this is mainly to give me an idea of the power of SQL. My problem: I have a list of words in the database that should be sorted alphabetically and grouped into separate groups according to the first letter of the word. For example: ape broom coconut banana apple should be returned as array( 'a' => 'ape', 'apple', 'b' => 'banana', 'broom', 'c' => 'coconut' ) so I can easily created sorted lists by first letter (i.e. clicking "A" only shows words starting with a, "B" with b, etc. This should make it easier for me to load everything in one query and make the sorted list JavaScript based, i.e. without having to reload the page (or use AJAX). Side notes: I'm using PostgreSQL but a solution for MySQL would be fine too so I can try to port it to PostgreSQL. Scripting language is PHP.

  • Disable Foreign Key Exposure in Entity Framework?

    - by davemackey
    When I originally created a Dynamic Data project I told it to expose the foreign keys, but now I can't make mappings between two entities b/c of the foreign keys. When I click on mapping details while focused on my association I receive the message: Mappings are not allow for an association over exposed foreign keys. So I'd like to disable the exposure of the foreign keys but am unsure how to do this without creating a new Entity Model from scratch. I'm not far along - so that wouldn't be hard, but I imagine there must be a programmatic switch for this?

  • GPG - why am I encrypting with subkey instead of primary key?

    - by khedron
    When encrypting a file to send to a collaborator, I see this message: gpg: using subkey XXXX instead of primary key YYYY Why would that be? I've noticed that when they send me an encrypted file, it also appears to be encrypted towards my subkey instead of my primary key. For me, this doesn't appear to be a problem; gpg (1.4.x, macosx) just handles it & moves on. But for them, with their automated tool setup, this seems to be an issue, and they've requested that I be sure to use their primary key. I've tried to do some reading, and I have the Michael Lucas's "GPG & PGP" book on order, but I'm not seeing why there's this distinction. I have read that the key used for signing and the key used for encryption would be different, but I assumed that was about public vs private keys at first. In case it was a trust/validation issue, I went through the process of comparing fingerprints and verifying, yes, I trust this key. While I was doing that, I noticed the primary & subkeys had different "usage" notes: primary: usage: SCA subkey: usage: E "E" seems likely to mean "Encryption". But, I haven't been able to find any documentation on this. Moreover, my collaborator has been using these tools & techniques for some years now, so why would this only be a problem for me?

  • PHP: parse $_FILES[] data in multidimesional array

    - by superUntitled
    I having been looking around for an answer to this and have not found an answer anywhere, I am hoping someone has done this before! I have a form that allows for dynamic duplication of the form fields. The form allows for file uploads and text input, so the data is sent in both $_POST and $_FILES arrays. The the initial set of inputs look like this: <input type="text" name="primary[1][text]" /> <input type="file" name="primary[1][file]" /> <input type="text" class="a" name="secondary[1][text][]" /> <input type="file" name="secondary[1][file][]" /> When duplicated the fields are incremented, they look like this: <input type="text" name="primary[2][text]" /> <input type="file" name="primary[2][file]" /> <input type="text" class="a" name="secondary[2][text][]" /> <input type="file" name="secondary[2][file][]" /> To complicate matters, the "secondary" form fields can also be duplicated (thus the [] at the end of the secondary name array. How can I parse the posted $_FILES array? I have tried something like this: foreach ($_FILES['question'] as $f_num) { echo $f['file']['name']; } but I get an "Undefined index: file... " error.

  • Holding variables in memory, C++

    - by b-gen-jack-o-neill
    Today something strange came to my mind. When I want to hold some string in C (C++) the old way, without using string header, I just create array and store that string into it. But, I read that any variable definition in C in local scope of function ends up in pushing these values onto the stack. So, the string is actually 2* bigger than needed. Because first, the push instructions are located in memory, but then when they are executed (pushed onto the stack) another "copy" of the string is created. First the push instructions, than the stack space is used for one string. So, why is it this way? Why doesn't compiler just add the string (or other variables) to the program instead of creating them once again when executed? Yes, I know you cannot just have some data inside program block, but it could just be attached to the end of the program, with some jump instruction before. And than, we would just point to these data? Because they are stored in RAM when the program is executed. Thanks.

  • php - using file() incrementally?

    - by NeedBeerStat
    I'm not sure if this is possible, I've been googling for a solution... But, essentially, I have a very large file, the lines of which I want to store in an array. Thus, I'm using file(), but is there a way to do that in batches? So that every,say, 100 lines it creates, it "pauses"? I think there's likely to be something I can do with a foreach loop or something, but I'm not sure that I'm thinking about it the right way... Like $i=0; $j=0; $throttle=100; foreach($files as $k => $v) { if($i < $j+$throttle && $i > $j) { $lines[] = file($v); //Do some other stuff, like importing into a db } $i++; $j++; } But, I think that won't really work because $i & $j will always be equal... Anyway, feeling muddled... Can someone help me think a lil' clearer?
