  • SQL return error within PHP

    - by Luke
    I use GET to get the id of a result. $id = $_GET['id']; I then use the following code: <? $q = $database->friendlyDetails($id); while( $row=mysql_fetch_assoc($q) ) { $hu = $row['home_user']; $ht = $row['home_team']; $hs = $row['home_score']; $au = $row['away_user']; $at = $row['away_team']; $as = $row['away_score']; $game = $row['game']; $name = $row['name']; $match = $row['match_report1']; $compid = $row['compid']; $date = $row['date_submitted']; $sub = $row['user_submitted']; } ?> And friendDetails- function friendlyDetails($i) { $q = "SELECT * FROM ".TBL_SUB_RESULTS." INNER JOIN ".TBL_FRIENDLY." ON ".TBL_FRIENDLY.".id = ".TBL_SUB_RESULTS.".compid WHERE ".TBL_SUB_RESULTS.".id = '$i'"; return mysql_query($q, $this->connection); } For some reason, the code will only return what is under id =1. Can anyone see anything obvious I am doing wrong?

  • Return REF CURSOR to procedure generated data

    - by ThaDon
    I need to write a sproc which performs some INSERTs on a table, and compile a list of "statuses" for each row based on how well the INSERT went. Each row will be inserted within a loop, the loop iterates over a cursor that supplies some values for the INSERT statement. What I need to return is a resultset which looks like this: FIELDS_FROM_ROW_BEING_INSERTED.., STATUS VARCHAR2 The STATUS is determined by how the INSERT went. For instance, if the INSERT caused a DUP_VAL_ON_INDEX exception indicating there was a duplicate row, I'd set the STATUS to "Dupe". If all went well, I'd set it to "SUCCESS" and proceed to the next row. By the end of it all, I'd have a resultset of N rows, where N is the number of insert statements performed and each row contains some identifying info for the row being inserted, along with the "STATUS" of the insertion Since there is no table in my DB to store the values I'd like to pass back to the user, I'm wondering how I can return the info back? Temporary table? Seems in Oracle temporary tables are "global", not sure I would want a global table, are there any temporary tables that get dropped after a session is done?

  • Determining presence of prototype with correct return type

    - by R..
    Here's a random problem in C black magic I just came up with: Write a function that returns 1 if malloc has been prototyped to return a pointer type and 0 if malloc has a return type of int (either implicitly or due to wrong prototype), without invoking any implementation-defined or undefined behavior. I believe it's solvable, but I haven't worked out the solution. Note that calling the function cannot be necessary and in fact is not possible since calling a function with the incorrect prototype is undefined behavior. I have some ideas for ingredients but I think it makes for a better puzzle (and possibly more diverse ideas) if I leave them out for now. I don't need the solution for any immediate use, but it could be handy in configure scripts and such. Update: A better example of the usefulness (with strdup instead of malloc): #undef strdup #define strdup(x) (strdup_has_proto ? strdup((x)) : my_strdup((x))) i.e. being able to implement X_has_proto as an expression at the source level could be a portable way to use functions which a system might or might not have, and fall back on a local replacement, without needing any separate configure step.

  • Distinct() to return List<> returning Duplicates

    - by KDM
    I have a list of Filters that are passed into a webservice and I iterate over the collection and do Linq query and then add to the list of products but when I do a GroupBy and Distinct() it doesn't remove the duplicates. I am using a IEnumerable because when you use Disinct it converts it to IEnumerable. If you know how to construct this better and make my function return a type of List<Product> that would be appreciated thanks. Here is my code in C#: if (Tab == "All-Items") { List<Product> temp = new List<Product>(); List<Product> Products2 = new List<Product>(); foreach (Filter filter in Filters) { List<Product> products = (from p in db.Products where p.Discontinued == false && p.DepartmentId == qDepartment.Id join f in db.Filters on p.Id equals f.ProductId join x in db.ProductImages on p.Id equals x.ProductId where x.Dimension == "180X180" && f.Name == filter.Name /*Filter*/ select new Product { Id = p.Id, Title = p.Title, ShortDescription = p.ShortDescription, Brand = p.Brand, Model = p.Model, Image = x.Path, FriendlyUrl = p.FriendlyUrl, SellPrice = p.SellPrice, DiscountPercentage = p.DiscountPercentage, Votes = p.Votes, TotalRating = p.TotalRating }).ToList<Product>(); foreach (Product p in products) { temp.Add(p); } IEnumerable temp2 = temp.GroupBy(x => x.Id).Distinct(); IEnumerator e = temp.GetEnumerator(); while (e.MoveNext()) { Product c = e.Current as Product; Products2.Add(c); } } pf.Products = Products2;// return type must be List<Product> }

  • How to loop through an array return from the Query of Mysql

    - by Jerry
    This might be easy for you guys but i could't get it. I have a php class that query the database and return the query result. I assign the result to an array and wants to use it on my main.php script. I have tried to use echo $var[0] or echo $var[1] but the output are 'array' instead of my value. Anyone can help me about this issue? Thanks a lot! My php class <?php class teamQuery { function teamQuery(){ } function getAllTeam(){ $connection = mysql_connect(DB_SERVER,DB_USER,DB_PASS); if (!$connection) { die("Database connection failed: " . mysql_error()); } $db_select = mysql_select_db(DB_NAME,$connection); if (!$db_select) { die("Database selection failed: " . mysql_error()); } $teamQuery=mysql_query("SELECT * FROM team", $connection); if (!$teamQuery){ die("database has errors: ".mysql_error()); } $ret = array(); while($row=mysql_fetch_array($teamQuery)){ $ret[]=$row; } mysql_free_result($teamQuery); return $ret; } } ?> My php on the main.php $getTeam=new teamQuery(); $team=$getTeam->getAllTeam(); //echo $team[0] or team[1] output 'array' string! // while($team){ // do something } can't work either // How to loop through the values?? Thanks!

  • Action on each method's return value

    - by RobGlynn
    What I'd like to do is take some action using the value returned by every method in a class. So for instance, if I have a class Order which has a method public Customer GetCustomer() { Customer CustomerInstance = // get customer return CustomerInstance; } Let's say I want to log the creation of these - Log(CustomerInstance); My options (AFAIK) are: Call Log() in each of these methods before returning the object. I'm not a fan of this because it gets unwieldy if used on a lot of classes with a lot of methods. It also is not an intrinsic part of the method's purpose. Use composition or inheritance to layer the log callon the Order class similar to: public Customer GetCustomer() { Customer CustomerInstance = this.originalCustomer.GetCustomer(); Log(CustomerInstance); return CustomerInstance; } I don't think this buys me anything over #1. Create extension methods on each of the returned types: Customer CustomerInstance = Order.GetCustomer().Log(); which has just as many downsides. I'm looking to do this for every (or almost every) object returned, automatically if possible, without having to write double the amount of code. I feel like I'm either trying to bend the language into doing something it's not supposed to, or failing to recognize some language feature that would enable this. Possible solutions would be greatly appreciated.

  • SLRequest return nil before block complete

    - by jaytr0n
    I'm having a little trouble thinking through this and deciding if it's a design flaw on my behalf or if I'm missing a piece that could make this work. Basically I'm using the new SLRequest to make a Twitter API call. After the data is returned, I'd like to put it into an object and return that object: -(AUDSlide *) getFollowerSlide { SLRequest *getRequest = [SLRequest requestForServiceType:SLServiceTypeTwitter requestMethod:SLRequestMethodGET URL:[NSURL URLWithString:[NSString stringWithFormat:@"https://api.twitter.com/1.1/followers/ids.json?user_id=%@", [[self.twitterAccount valueForKey:@"properties"] valueForKey:@"user_id"]]] parameters:nil]; getRequest.account = twitterAccount; AUDSlide *slide = [[AUDSlide alloc] init]; [getRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) { if ([urlResponse statusCode] == 200) { NSError *jsonError = nil; NSDictionary *list = [NSJSONSerialization JSONObjectWithData:responseData options:0 error:&jsonError]; NSLog(@"Number of Followers: %u", [[list objectForKey:@"ids"] count]); slide.title = @"Followers"; slide.number = [NSString stringWithFormat:@"%u",[[list objectForKey:@"ids"] count]]; } else{ slide.title = @"Error"; slide.number = [NSString stringWithFormat: @"E%u", [urlResponse statusCode]]; } }]; return slide; } Of course the slide is returned before the call is complete and returns a nil object. So I'm not sure if I should try to force this into a synchronous request (that seems like it could be a bad idea) or rethink the design. Does anyone have any advice?

  • jQuery - Cancel form submit (using "return false"?)?

    - by Nike
    Hey there. I'm running into a bit of trouble while trying to cancel the submit of a form. I've been following this tutorial (even though i'm not making a login script), and it seems to be working for him. Here's my form: <form action="index.php" method="post" name="pForm"> <textarea name="comment" onclick="if(this.value == 'skriv här...') this.value='';" onblur="if(this.value.length == 0) this.value='skriv här...';">skriv här...</textarea> <input class="submit" type="submit" value="Publicera!" name="submit" /> </form> And here's the jquery: $(document).ready(function() { $('form[name=pForm]').submit(function(){ return false; }); }); I've already imported jQuery in the header and i know it's working. My first thought was that it might be outdated, but it's actually "just" a year ago. So do anyone see what's wrong? Thanks in advance. EDIT: From what i've read the easiest and most appropriate way to abort the submit is to return false? But i can't seem to get it working. I've searched the forum and i've found several helpful threads but none of them actually works. I must be screwing something up.

  • Javascript - Wait for function to return

    - by LoadData
    So, I am working on a project which requires me to call upon a function to get data from an external source. The issue I am having, I call upon the function - However the code after the function call is continuing before the function has returned a value. Here is the function - function getData() { var myVar; var xmlLoc = $.get("http://ec.urbentom.co.uk/StudentAppData.xml", function(data) { $xml = $(data); myVar = $xml; console.log(myVar); console.log(String($xml)); localStorage.setItem("Data", $xml); console.log(String(localStorage.getItem("Data"))); return myVar; }); return myVar; console.log("Does this continue"); } And here is where it is called upon - $(document).on("pageshow","#Information",function() { $xml = $(getData()); //Here is the function call console.log($xml); //However, it will instantly go to this line before 'getData' has returned a value. $xml.find('AllData').each(function() { $(this).find('item').each(function() { if ($(this).find('Category').text()=="Facilities") { console.log($(this).find('Title').text()); //Do stuff here } else if ($(this).find('Category').text()=="Contacts" || $(this).find('Category').text()=="Information") { console.log($(this).find('Title').text()); //Do stuff here too } }); $('#informationList').html(output).listview().listview("refresh"); console.log("Finished"); }); }); Right now, I'm unsure of why it is not working. My guess is that it is because I am calling a function within a function. Does anyone have any ideas on how this issue can be fixed?

  • recvfrom() return values in Stop-and-Wait UDP?

    - by mavErick
    I am trying to implement a Stop-and-Wait UDP client-server socket program in C. As known, there are basically three possible scenarios for Stop-and-Wait flow control. i.e., After transmitting a packet, the sender receives a correct ACK and thus starts transmitting the next packet; the sender receives an incorrect ACK and thus retransmits this packet; the sender receives no ACK within a TIMEOUT and thus retransmits this packet. My idea is to differentiate these three scenarios with the return value of recvfrom() on the sender side. For scenario 1&2: recvfrom() just returns the length of the received ACK. Since in my implementation the incorrect ACK is of the same length of the correct one, so I will have to go deeper and check the contents of the ACK. It's not a big deal. I know how to do. Problems come when I am trying to recognize scenario 3 where no ACK is received. What confuses me is that my recvfrom() is within a while loop, so the recvfrom() will be called constantly. What will it return when the receiver is not actually sending the sender ACK? Is it 0 or 1?

  • regex return conditional group

    - by priyank.mp
    Hi , I spent lot time figuring out a simple regex to return a group (only 1st group). So the string can be - "No purchase required" or "Purchase of $50.00 worth groceries is required." I am trying to write a regex which can parse "No" or "50" based on the given string. This is what I have written. (?:(No) monthly maintenance|Purchase of \$([\d\.]+ worth groceries) This works fine but I want my output as 1st group/group 1 only.

  • Facebook API call with email to return UID

    - by Jackson
    I'm trying to do a simple API call with facebook, with a user-given email to return their uid. Do I really need to auth them before this call is made? Thanks! :) I'm not doing anything else with the UID besides displaying to the user, which is why I don't really think it's worth authenticating them.

    I have a jquery post function that returns a response on success after the click of a div. However, I would like to return multiple variables on success. Do I have to use JSON, and if so, is it possible to integrate it into the $.ajax function after success? $.ajax({ type: "POST", data: "action=favorite&username=" + username + "&topic_id=" + topic_id + "&token=" + token, url: "favorite.php", success: function(response) { } });

  • can ServiceLocator.Current.GetInstance return null?

    - by mauricio076
    I have this piece of code (or similar) in many of our views: private IEventAggregator eventAggregator; Constructor() { eventAggregator = ServiceLocator.Current.GetInstance<IEventAggregator>(); ... } I read from this post that ServiceLocator.Current can throw NullReferenceException (bad thing on a constructor) but I was wondering if the GetInstance<() method can return null (or some other inconsistent object) making eventAggregator dangerous to use later in other methods. NOTE: I'm quite new to MVVM and WPF

  • How does fork() return for child process

    - by EpsilonVector
    I know that fork() returns differently for the son and father processes, but I'm unable to find information on how this happens. How does the son process receive the return value 0 from fork? And what is the difference in regards to the call stack? As I understand it, for the father it goes something like this: father process--invokes fork--system_call--calls fork--fork executes--returns to--system_call--returns to--father process. What happens in the son side?

  • Zend Mail - bouncing mails not returning to the specified "Return-Path"

    - by Leprosy
    Hi, i'm working on a simple mail list app in PHP using Zend Mail. The idea is that all mail that bounce is redirected to a script which processes them and a report is generated. The script is running ok in direct tests, but I've testing it with fake mail address to test the mail list app, and it appears that the mail is not being redirected to the correct email address. Zend Mail provides the setReturnPath method to set the "Return-Path" header, it's ok to use this header for this purpose? Thanks

  • jquery function to convert datetime, split date time "2010-10-18 10:06" to return "18/10/2010" and

    - by Cesar Lopez
    Hi I was wondering if there is any jquery function around which can take this dateTime "2010-10-18 10:06" and convert and split it returning "2010/10/18" and "10:06". It would be also nice if the same function could either receive "2010-10-18 10:06" or "2010-10-18" only and return as mentioned above, or different formats besides "2010/10/18" like 18-10-2010" or and 18th of October 2010, giving the option but not that important, just curious about jQuery power dealing with dates. Thanks.

  • DateTime.Now.Millisecond always return 0 on compact framework

    - by Sachin
    I need some way to find the elapsed time or time taken in milliseconds for a function to execute in compact framework. For the same I tried DateTime.Now.Millisecond. But DateTime.Now.Millisecond always return 0. Also I tried with Now.Tick. But it also returns the value in multiplication of 1,00,00,000 which means it always returns seconds part ignoring the milliseconds. My question is how to determine the time elapsed in millisecond on compact framework.

  • Access external xml using xslt document function return 401

    - by Ciprian Grosu
    On MOSS2007, I have a webpart that display the content of a xml feed. I use a xslt with parameters for transforamtions. There is a situation when I receive a 401 Authorisation exception. I realize that this happen when a document() function from my xslt try to open an external xml. If I try to open this xml in browser all work ok. I provided my admin credentials to the web part and to the XmlSecureResolver. Same problem. The webpart is on server1 and the xml feed and external xml required by xslt is on server2. What can be ? protected override void RenderContents(HtmlTextWriter writer) { base.RenderContents(writer); if (string.IsNullOrEmpty(this.xmlUrl) || this.xmlResponseStream == null) return; try { XslCompiledTransform transform = new XslCompiledTransform(); if (UseXslt) { XmlTextReader stylesheet = null; try { SPSite site = new SPSite(xsltlUrl); SPWeb web = site.OpenWeb(); SPFile file = web.GetFile(xsltlUrl); if (file != null) { stylesheet = new XmlTextReader(file.OpenBinaryStream()); } } catch(Exception ex) { stylesheet = new XmlTextReader(xsltlUrl); } if (stylesheet != null) { transform.Load(stylesheet, new XsltSettings(true, true), GetAResolver()); } using (XmlReader reader = new XmlTextReader(this.xmlResponseStream)) { string theParams = xsltProperties; XsltArgumentList xslAgrs = GetXsltArgumentList(xsltProperties); XmlTextWriter results = new XmlTextWriter(writer.InnerWriter); if (UseProperties) { transform.Transform(reader, xslAgrs, results, GetASecureResolver()); } else { transform.Transform(reader, results); } reader.Close(); } } else { string feedAsString = null; using (StreamReader rssReader = new StreamReader(this.xmlResponseStream)) { feedAsString = rssReader.ReadToEnd(); writer.InnerWriter.Write(SPHttpUtility.HtmlEncode(feedAsString)); } } } catch (Exception ex) { writer.Write(ex.Message); if (this.xmlResponseStream != null) { this.xmlResponseStream.Close(); this.xmlResponseStream.Dispose(); } } } private static XmlSecureResolver GetASecureResolver() { // Create a secure resolver XmlSecureResolver resolver = new XmlSecureResolver(new XmlUrlResolver(), "http://externalservername.com/thesite/"); string proxyUserName = RssFeedUtility.GetConfigFileReader().ProxyUserName; string proxyUserPwd = RssFeedUtility.GetConfigFileReader().ProxyUserPassword; string proxyUserDomain = RssFeedUtility.GetConfigFileReader().ProxyUserDomain; resolver.Credentials = new NetworkCredential(proxyUserName, proxyUserPwd, proxyUserDomain); return resolver; }
