  • Using a function found in a different file in a loop

    - by Anders
    This question is related to BuddyPress, and a follow-up question from this question I have a .csv-file with 790 rows and 3 columns where the first column is the group name, second is the group description and last (third) the slug. As far as I've been told I can use this code: <?php $groups = array(); if (($handle = fopen("groupData.csv", "r")) !== FALSE) { while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) { $group = array('group_id' = 'SOME ID', 'name' = $data[0], 'description' = $data[1], 'slug' = groups_check_slug(sanitize_title(esc_attr($data[2]))), 'date_created' = gmdate( "Y-m-d H:i:s" ), 'status' = 'public' ); $groups[] = $group; } fclose($handle); } foreach ($groups as $group) { groups_create_group($group); } With http://www.nomorepasting.com/getpaste.php?pasteid=35217 which is called bp-groups.php. The thing is that I can't make it work. I've created a new file with the code written above called groupgenerator.php uploaded the .csv file to the same folder and opened groupgenerator.php in my browser. But, i get this error: Fatal error: Call to undefined function groups_check_slug() in What am I doing wrong?

  • Presenting collection of structures of strings in grid or similar in WPF - Example? Ideas?

    - by Andrew
    Hi, I have a collection of structures. The structure is just some strings. Example public struct ReportLine { public string Name; public string Address; public string Phone; ...// about 10 other strings } I can't change this part. What I want to do is display it in a simple grid or simlar in WPF. My only requirements are: a) need column headers b) rows must alternate in color c) columns big enough to hold largest datum (which is not know until run time) Can someone point me to an example to get me started? Is the GridView the way to go? Or DataGrid? Or perhaps just the grid? I have the book Pro WPF in C# 2008 and it covers binding ListBox's to collections, but the collections always seem to be collections of one field (ex. a collection of 40 names). Here I have a collection (an array in fact) of a structure. How do I setup the databinding? As you can see, I'm new to this and probably would most benefit from a reference to an article. I've found articles covering collections of 1 field, but no examples covering binding to an array of structures. Also, my intitial research indicates c) can't be easily done, if you demand that the column is big enough for all the data in that column, not just the visible data. Thanks, dave

  • Running a Model::find in for loop in cakephp v1.3

    - by Gaurav Sharma
    Hi all, How can I achieve the following result in cakephp: In my application a Topic is related to category, category is related to city and city is finally related to state in other words: topic belongs to category, category belongs to city , city belongs to state.. Now in the Topic controller's index action I want to find out all the topics and it's city and state. How can I do this. I can easily do this using a custom query ($this-Model-query() function ) but then I will be facing pagination difficulties. I tried doing like this function index() { $this->Topic->recursive = 0; $topics = $this->paginate(); for($i=0; $i<count($topics);$i++) { $topics[$i]['City'] = $this->Topic->Category->City->find('all', array('conditions' => array('City.id' => $topics[$i]['Category']['city_id']))); } $this->set(compact('messages')); } The method that I have adopted is not a good one (running query in a loop) Using the recursive property and setting it to highest value (2) will degrade performance and is not going to yield me state information. How shall I solve this ? Please help Thanks

  • Objective C map view delegate viewForAnnotation for MKAnnotation gets just called after click

    - by user1185486
    I have a simple Map view. It has a method -(void)loadAndDisplayPois{ NSLog(@"loadAndDisplayPois"); if(mapView.annotations.count > 0) [mapView removeAnnotations:mapView.annotations]; self.pois = [self loadPoisFromDatabase]; NSLog(@"self.pois.count: %i", self.pois.count); [mapView addAnnotations:self.pois]; NSLog(@"mapView.annotations.count: %i",mapView.annotations.count);} This method gets called, and I am sure that the method gets called because of the Log, after I downloaded data and saved it into the database. The class which handles the download executes after saving the data to the database [self.senderObj performSelector:@selector(loadAndDisplayPois)]; Where senderObj is the MapViewControlller. The count Log from the pois array shows 4 after the first time I clicked. But no Annotations on the view, because viewForAnnotation is not called (one Annotation in the array ( my current position)). After I execute the method again by clicking a TEST button shows everything on the map. The viewForAnnotation method gets called after viewWillAppear and after I clicked the TEST button. It is driving me nuts since 2 days. I cant anymore ...

  • removing phone number from a document.

    - by Grant Collins
    Hi, I've got a challenge that I am hoping that the SO community is able to help me with. I trying to parse a lot of html documents in my PHP application to remove personal details, such as names, addresses and phone numbers. I can remove most of these details without too much trouble, however the phone number is a real problem for me. My idea is to take the text from these documents and the use a regex to identify the phone numbers and replace them with another value such as 'xxxx'. I've got 2 regex that I am using one for UK landline numbers and one for UK cell/mobile numbers. However when I try and run them against the text it just returns an empty string. I am using the following preg_replace code: $pattens = array( '/^(((\+44\s?\d{4}|\(?0\d{4}\)?)\s?\d{3}\s?\d{3})|((\+44\s?\d{3}|\(?0\d{3}\)?)\s?\d{3}\s?\d{4})|((\+44\s?\d{2}|\(?0\d{2}\)?)\s?\d{4}\s?\d{4}))(\s?\#(\d{4}|\d{3}))?$/', '/^(\+44\s?7\d{3}|\(?07\d{3}\)?)\s?\d{3}\s?\d{3}$/' ); $replace = array('xxxxx', 'xxxxx'); //do the search for the numbers. $updatedContents = preg_replace($pattens, $replace, $htmlContents); At the moment this is causing me a lot of head scratching as I thought that I had this nailed, but at the moment I can't see what's wrong?? I am sure that it is something really simple. Thanks, Grant

  • How to change value inside a JSON string.

    - by Jeremy Roy
    I have a JSON string array of objects like this. [{"id":"4","rank":"adm","title":"title 1"}, {"id":"2","rank":"mod","title":"title 2"}, {"id":"5","rank":"das","title":"title 3"}, {"id":"1","rank":"usr","title":"title 4"}, {"id":"3","rank":"ref","title":"title 5"}] I want to change the title value of it, once the id is matching. So if my variable myID is 5, I want to change the title "title 5" to new title, and so on. And then I get the new JSON array to $("#rangArray").val(jsonStr); Something like $.each(jsonStr, function(k,v) { if (v==myID) { this.title='new title'; $("#myTextArea").val(jsonStr); } }); Here is the full code. $('img.delete').click(function() { var deltid = $(this).attr("id").split('_'); var newID = deltid[1]; var jsonStr = JSON.stringify(myArray); $.each(jsonStr, function(k,v) { if (v==newID) { // how to change the title jsonStr[k].title = 'new title'; alert(jsonStr); $("#rangArray").val(jsonStr); } }); }); The above is not working. Any help please?

  • d3: Coloring Multiple Lines from Nested Data

    - by diet_coke
    I'm currently assembling some line graphs with circles at the datapoints from arrays of JSON objects formatted like so: var data = [{ "name": "metric1", "datapoints": [ [10.0, 1333519140], [48.0, 1333519200] ] }, { "name": "metric2", "datapoints": [ [48.0, 1333519200], [12.0, 1333519260] ] }] I want to have a color for each metric, so I'm trying to color them based on the index of the object within the array data. The code I have currently for just placing the circles looks like: // We bind an svg group to each metric. var metric_groups = this.vis.selectAll("g.metric_group") .data(data).enter() .append("g") .attr("class", "metric_group"); // Then bind a circle for each datapoint. var circles = metric_groups.selectAll("circle") .data(function(d) { return d.datapoints; }); circles.enter().append("circle") .attr("r", 3.5); Now if I change that last bit to something like: circles.enter().append("circle") .attr("r", 3.5); .style("fill", function(d,i) { return i%2 ? "red" : "blue"; } I get alternating red and blue circles, as could be expected. Taking some advice from Nested Selections : 'Nesting and Index', I tried: circles.enter().append("circle") .attr("r", 3.5); .style("fill", function(d,i,j) { return j%2 ? "red" : "blue"; } Which doesn't work (j is undefined), presumably because we are in the named property datapoints, rather than an array element. How might I go about doing the coloring that I want without changing my data structure? Thanks!

  • Referencing not-yet-defined variables - Java

    - by user2537337
    Because I'm tired of solving math problems, I decided to try something more engaging with my very rusty (and even without the rust, very basic) Java skills. I landed on a super-simple people simulator, and thus far have been having a grand time working through the various steps of getting it to function. Currently, it generates an array of people-class objects and runs a for loop to cycle through a set of actions that alter the relationships between them, which I have stored in a 2d integer array. When it ends, I go look at how much they all hate each other. Fun stuff. Trouble has arisen, however, because I would like the program to clearly print what action is happening when it happens. I thought the best way to do this would be to add a string, description, to my "action" class (which stores variables for the actor, reactor, and the amount the relationship changes). This works to a degree, in that I can print a generic message ("A fight has occurred!") with no problem. However, ideally I would like it to be a little more specific ("Person A has thrown a rock at Person B's head!"). This latter goal is proving more difficult: attempting to construct an action with a description string that references actor and reactor gets me a big old error, "Cannot reference field before it is defined." Which makes perfect sense. I believe I'm not quite in programmer mode, because the only other way I can think to do this is an unwieldy switch statement that negates the need for each action to have its own nicely-packaged description. And there must be a neater way. I am not looking for examples of code, only a push in the direction of the right concept to handle this.

  • unable to return 'true' value in C function

    - by Byron
    If Im trying to check an input 5 byte array (p) against a 5 byte array stored in flash (data), using the following function (e2CheckPINoverride), to simply return either a true or false value. But it seems, no matter what I try, it only returns as 'false'. I call the function here: if (e2CheckPINoverride(pinEntry) == 1){ PTDD_PTDD1 = 1; } else{ PTDD_PTDD1 = 0; } Here is the function: BYTE e2CheckPINoverride(BYTE *p) { BYTE i; BYTE data[5]; if(e2Read(E2_ENABLECODE, data, 5)) { if(data[0] != p[0]) return FALSE; if(data[1] != p[1]) return FALSE; if(data[2] != p[2]) return FALSE; if(data[3] != p[3]) return FALSE; if(data[4] != p[4]) return FALSE; } return TRUE; } I have already assigned true and false in the defines.h file: #ifndef TRUE #define TRUE ((UCHAR)1) #endif #ifndef FALSE #define FALSE ((UCHAR)0) #endif and where typedef unsigned char UCHAR; when i step through the code, it performs all the checks correctly, it passes in the correct value, compares it correctly and then breaks at the correct point, but is unable to process the return value of true? please help?

  • Calculating and saving space in Postgresql

    - by punkish
    I have a table in Pg like so CREATE TABLE t ( a BIGSERIAL NOT NULL, -- 8 b b SMALLINT, -- 2 b c SMALLINT, -- 2 b d REAL, -- 4 b e REAL, -- 4 b f REAL, -- 4 b g INTEGER, -- 4 b h REAL, -- 4 b i REAL, -- 4 b j SMALLINT, -- 2 b k INTEGER, -- 4 b l INTEGER, -- 4 b m REAL, -- 4 b CONSTRAINT a_pkey PRIMARY KEY (a) ) The above adds up to 50 bytes per row. My experience is that I need another 40% to 50% for system overhead, without even any user-created indexes to the above. So, about 75 bytes per row. I will have many, many rows in the table, potentially upward of 145 billion rows, so the table is going to be pushing 13-14 Terabytes. What tricks, if any, could I use to compact this table? My possible ideas below -- Convert the REAL values to INTEGERs. If they can stored as SMALLINT, that is a saving of 2 bytes per field. Convert the columns b .. m into an array. I don't need to search on those columns, but I do need to be able to return one column's value at a time. So, if I need column g, I could do something like SELECT a, arr[5] FROM t; Would I save space with the array option? Would there be a speed penalty? Any other ideas?

  • How do I get a less than in a javascript for loop in XSL to work?

    - by Kyle
    I am using CDATA to escape the script but in IE8's debugger I still get this message: "Expected ')'" in the for loop conditions. I am assuming it still thinks that the ; in the &lt; generated by CDATA is ending the loop conditions. Original script in my XSL template: <script type="text/javascript" language="javascript"> <![CDATA[ function submitform(form){ var oErrorArray = new Array(); for (i=0;i<form.length;i++) eval("oErrorArray["+i+"]=oError"+i); var goForm = true; for(i=0;i<form.length;i++) { oErrorArray[i].innerHTML = ""; if(form[i].value="")){ oErrorArray[i].innerHTML = "Error - input field is blank"; goForm = false; } } if(goForm == true) form.submit(); } function resetform(form){ form.reset(); } ]]> </script> Code generated after transformation (from IE8 debugger): <script type="text/javascript" language="javascript"> function submitform(form){ var oErrorArray = new Array(); for (i=0;i&lt;form.length;i++) eval("oErrorArray["+i+"]=oError"+i); goForm = true; for(i=0;i&lt;form.length;i++) { oErrorArray[i].innerHTML = ""; if(form[i].value="")){ oErrorArray[i].innerHTML = "Error - input field is blank"; goForm = false; } } if(goForm == true) form.submit(); } function resetform(form){ form.reset(); } </script> Error reported by IE8 debugger: Expected ')' login.xml, line 29 character 30 (which is right after the first "form.length")

  • Avoid an "out of memory error" in Java(eclipse), when using large data structure?

    - by gnomed
    OK, so I am writing a program that unfortunately needs to use a huge data structure to complete its work, but it is failing with a "out of memory error" during its initialization. While I understand entirely what that means and why it is a problem, I am having trouble overcoming it, since my program needs to use this large structure and I don't know any other way to store it. The program first indexes a large corpus of text files that I provide. This works fine. Then it uses this index to initialize a large 2D array. This array will have nXn entries, where "n" is the number of unique words in the corpus of text. For the relatively small chunk I am testing it on(about 60 files) it needs to make approximately 30,000x30,000 entries. this will probably be bigger once I run it on my full intended corpus too. It consistently fails every time, after it indexes, while it is initializing the data structure(to be worked on later). Things I have done include: revamp my code to use a primitive "int[]" instead of a "TreeMap" eliminate redundant structures, etc... Also, I have run eclipse with "eclipse -vmargs -Xmx2g" to max out my allocated memory I am fairly confident this is not going to be a simple line of code solution, but is most likely going to require a very new approach. I am looking for what that approach is, any ideas? Thanks, B.

  • Creating a RESTful API - HELP!

    - by Martin Cox
    Hi Chaps Over the last few weeks I've been learning about iOS development, which has naturally led me into the world of APIs. Now, searching around on the Internet, I've come to the conclusion that using the REST architecture is very much recommended - due to it's supposed simplicity and ease of implementation. However, I'm really struggling with the implementation side of REST. I understand the concept; using HTTP methods as verbs to describe the action of a request and responding with suitable response codes, and so on. It's just, I don't understand how to code it. I don't get how I map a URI to an object. I understand that a GET request for domain.com/api/user/address?user_id=999 would return the address of user 999 - but I don't understand where or how that mapping from /user/address to some method that queries a database has taken place. Is this all coded in one php script? Would I just have a method that grabs the URI like so: $array = explode("/", ltrim(rtrim($_SERVER['REQUEST_URI'], "/"), "/")) And then cycle through that array, first I would have a request for a "user", so the PHP script would direct my request to the user object and then invoke the address method. Is that what actually happens? I've probably not explained my thought process very well there. The main thing I'm not getting is how that URI /user/address?id=999 somehow is broken down and executed - does it actually resolve to code? class user(id) { address() { //get user address } } I doubt I'm making sense now, so I'll call it a day trying to explain further. I hope someone out there can understand what I'm trying to say! Thanks Chaps, look forward to your responses. Martin p.s - I'm not a developer yet, I'm learning :)

  • MSForms.ListBox Type Mismatch in Access

    - by Jason
    I have an Access database where I use a Tab control (without tabs) to simulate a wizard. One of the tab pages has an MSForms.ListBox control called lstPorts, and a button named cmdAdd which adds the contents of a textbox to the List Box. I then try to keep the contents of the ListBox sorted. However, the call to the Sort method causes a type mismatch. Here is the cmdAdd_Click() code behind: Private Sub cmdAdd_Click() Dim test As MSForms.ListBox lstPorts2.AddItem (txtPortName) Call SortListBox(lstPorts2) End Sub Here is the SortListBox Sub: Public Sub SortListBox(ByRef oLb As MSForms.ListBox) Dim vaItems As Variant Dim i As Long, j As Long Dim vTemp As Variant 'Put the items in a variant array vaItems = oLb.List For i = LBound(vaItems, 1) To UBound(vaItems, 1) - 1 For j = i + 1 To UBound(vaItems, 1) If vaItems(i, 0) > vaItems(j, 0) Then vTemp = vaItems(i, 0) vaItems(i, 0) = vaItems(j, 0) vaItems(j, 0) = vTemp End If Next j Next i 'Clear the listbox oLb.Clear 'Add the sorted array back to the listbox For i = LBound(vaItems, 1) To UBound(vaItems, 1) oLb.AddItem vaItems(i, 0) Next i End Sub Any help out there?

  • sql statement question. Need to query 3 tables in one go!

    - by Stefan
    Hey there, I have an sql database. In this database is 3 tables I need to query. The first table has all the item info called item and the other two tables has data for votes and comments called userComment and the third for votes called userItem I currently have a function which uses this sql query to get the latest more popular (in terms of both votes and comments): $sql = "SELECT itemID, COUNT(*) AS cnt FROM ( SELECT `itemID` FROM `userItem` WHERE FROM_UNIXTIME( `time` ) >= NOW() - INTERVAL 1 DAY UNION ALL SELECT `itemID` FROM `userComment` WHERE FROM_UNIXTIME( `time` ) >= NOW() - INTERVAL 1 DAY AND `itemID` > 0 ) q GROUP BY `itemID` ORDER BY cnt DESC"; I know how to change this for either by votes alone or comments.... HOWEVER - I need to query the database to only return the itemID's of the ones which have specific conditions in only the item table these are WHERE categoryID = 'xx' AND typeID = 'xx' If the sql ninja could please help me on this one? Do I have to first return the results from the above query and the for each in the array fetched then check each against the item table and see if it fits the conditions to build a new array - or is that overkill?

For example i need a Function CreateDynArray(Dimensions:array of integer; Kind:TTypeKind):TValue; and the function will return a TValue which is a dynamic array how contain the dimenssions for example: Return=CreateDynArray([2,3],tkInteger); will return a TValue as tkDynArray and if i will show(Return) will list 0 0 0 0 0 0 Thank you very much, and have a nice day!

  • Rand(); with exclusion to and already randomly generated number..?

    - by Stefan
    Hey, I have a function which calls a users associated users from a table. The function then uses the rand(); function to chose from the array 5 randomly selected userID's however!... In the case where a user doesnt have many associated users but above the min (if below the 5 it just returns the array as it is) then it gives bad results due to repeat rand numbers... How can overcome this or exclude a previously selected rand number from the next rand(); function call. Here is the section of code doing the work. Bare in mind this must be highly efficient as this script is used everywhere. $size = sizeof($users)-1; $nusers[0] = $users[rand(0,$size)]; $nusers[1] = $users[rand(0,$size)]; $nusers[2] = $users[rand(0,$size)]; $nusers[3] = $users[rand(0,$size)]; $nusers[4] = $users[rand(0,$size)]; return $nusers; Thanks in advance!

  • Php - divide time period into equal intervals

    - by experc
    Hi! I am working on my php course project and for the past few days I have stucked at the point where I have to create php function which gets 5 parameters which represents information about the working time of some department - when the work starts/ends, when the lunchtime (or any other break) starts/ends and integer representing minutes into how small piecies we should divide time period. Besides - it's possible that there are not any breaks in the working time. The function should return all intervals from working time. function split_time_into_intervals($work_starts,$work_ends,$break_starts=null; $break_ends=null,$minutes_per_interval=60){ $intervals=array(); //all of the function code return $intervals; } So if I have the following parameters for the function function split_time_into_intervals("8:30","14:50","11:45"; "12:25"){ .. } I would like to retrieve the following array: $intervals[0]['starts']="8:30"; $intervals[0]['ends']="9:30"; $intervals[1]['starts']="9:30"; $intervals[1]['ends']="10:30"; $intervals[2]['starts']="10:30"; $intervals[2]['ends']="11:30"; $intervals[3]['starts']="11:30"; $intervals[3]['ends']="11:45"; //this interval was smaller than 60 minutes - because of the break (which starts at 11:45) $intervals[4]['starts']="12:25";//starts when the break ends $intervals[4]['ends']="13:25"; // interval is again 60 minutes $intervals[5]['starts']="13:25"; $intervals[5]['ends']="14:25"; $intervals[6]['starts']="14:25"; $intervals[6]['ends']="14:50"; //this period is shorter than 60 minutes - because work ends Any advises? I would apriciate any php (or C#) code regarding to this problem!

  • figuring out which field to look for a value in with SQL and perl

    - by Micah
    I'm not too good with SQL and I know there's probably a much more efficient way to accomplish what I'm doing here, so any help would be much appreciated. Thanks in advance for your input! I'm writing a short program for the local school high school. At this school, juniors and seniors who have driver's licenses and cars can opt to drive to school rather than ride the bus. Each driver is assigned exactly one space, and their DLN is used as the primary key of the driver's table. Makes, models, and colors of cars are stored in a separate cars table, related to the drivers table by the License plate number field. My idea is to have a single search box on the main GUI of the program where the school secretary can type in who/what she's looking for and pull up a list of results. Thing is, she could be typing a license plate number, a car color, make, and model, someone driver's name, some student driver's DLN, or a space number. As the programmer, I don't know what exactly she's looking for, so a couple of options come to mind for me to build to be certain I check everywhere for a match: 1) preform a couple of SELECT * FROM [tablename] SQL statements, one per table and cram the results into arrays in my program, then search across the arrays one element at a time with regex, looking for a matched pattern similar to the search term, and if I find one, add the entire record that had a match in it to a results array to display on screen at the end of the search. 2) take whatever she's looking for into the program as a scaler and prepare multiple select statements around it, such as SELECT * FROM DRIVERS WHERE DLN = $Search_Variable SELECT * FROM DRIVERS WHERE First_Name = $Search_Variable SELECT * FROM CARS WHERE LICENSE = $Search_Variable and so on for each attribute of each table, sticking the results into a results array to show on screen when the search is done. Is there a cleaner way to go about this lookup without having to make her specify exactly what she's looking for? Possibly some kind of SQL statement I've never seen before?

  • Matching innermost braces with regex or strpos?

    - by rich97
    I have a sort of mini parsing syntax I made up to help me streamline my view code in cakephp. Basically I have created a table helper which, when given a dataset and (optionally) a set of options for how to format the data will render out a table, as opposed to me looping though the data and editing it manually. It allows the user to be as complex or as simple as they like, it can get pretty powerful. However, In order to achieve this I had to make a simple parsing syntax. As a quick example the user would do something like so: $this->Table->data = $userData; $this->Table->elements['td']['data'] = array( '{:User.username:}', '{:User.created:}' => array('Time::nice') ); echo $this->Table->render(); And when rendering the table would then generate: <table> <tbody> <tr><td>rich97</td><td>Sun 21st 02:30pm</td></tr> </tbody> </table> The problem occurs then I try to nest the braces like so: {:User.levels.iconClasses.{:User.access:}:} Is there anyway I can only get the inner most brackets on the first time round and loop though until there are no matches? Or even do it in one go? Or even better use strpos? Here is my regex as it stands: '/\{\:([^}]+)\:\}/'
