  • Using AJAX to POST data to PHP database, then refresh

    - by cb74656
    Currently I have a button: <ul> <li><button onclick="display('1')">1</button></li> <li><button onclick="display('2')">2</button></li> <li><button onclick="display('3')">3</button></li> </ul> That when pressed, calls a javascript function, and displays PHP based on which button is pressed using AJAX. I figured this out all on my own. The AJAX gets a PHP file with a postgres query that outputs a table of data to a div. Now I want to be able to add, via form, new data and have it refresh (without reloading the page, yannknow?). I've tried a couple of things, and have hit roadblocks every time. My initial idea was to have the form submit the data using a javascript function and AJAX, then call my "display()" function after the query to reload the content. I just can't figure it out using GoogleFu. Based on my current idea, I'd like help with the following: How do I pass the form data to a javascript function. How do I use POST to pass that data to PHP using AJAX? I'm super new to javascript and AJAX. I've looked into jquery as it seems like that's the way to go, but I can't figure it out. If there's a better way to do this, I'm open to suggestions. Please forgive any misuse of nomenclature. EDIT: Once I solve this problem..., I'll have all the tools needed to finish the project preliminarily.

  • question about permutation problem

    - by davit-datuashvili
    i have posted similar problem here http://stackoverflow.com/questions/2920315/permutation-of-array but i want following we know that with length n there is n! possible permutation from which one such that all element are in order they are in sorted variant so i want break permutation when array is in order and print result but something is wrong i think that problem is repeated of permutation here is my code import java.util.*; public class permut{ public static Random r=new Random(); public static void display(int a[],int n){ for (int i=0;i<n;i++){ System.out.println(a[i]); } } public static void Permut(int a[],int n){ int j=0; int k=0; while (j<fact(n)){ int s=r.nextInt(n); for (int i=0;i<n;i++){ k=a[i]; a[i]=a[s]; a[s]=k; } j++; if (sorted(a,n)) display(a,n); break; } } public static void main(String[]args){ int a[]=new int[]{3,4,1,2}; int n=a.length; Permut(a,n); } public static int fact(int n){ if (n==0 || (n==1) ) return 1; return n*fact(n-1); } public static boolean sorted(int a[],int n ){ boolean flag=false; for (int i=0;i<n-1;i++){ if (a[i]<a[i+1]){ flag=true; } else{ flag=false; } } return flag; } } can anybody help me? result is nothing

  • PasswordFiled char[] to String in Java connection MySql?

    - by user1819551
    This is a jFrame to connect to the database and this is in the button connect. My issue is in the passwordField NetBeans make me do a char[], but my .getConnection not let me insert the char[] ERROR: "no suitable method found for getConnection(String,String,char[])". So I will change to String right? So when I change and run the jFrame said access denied. when I start doing the System.out.println(l) " Give me the right answer" Like this: "Alex". But when I do the System.out.println(password) "Give me the Array spaces and not the value" Like this: jdbc:mysql://localhost/home inventory root [C@5be5ab68 <--- Array space . What I doing wrong? try { Class.forName("org.gjt.mm.mysql.Driver"); //Load the driver String host = "jdbc:mysql://"+tServerHost.getText()+"/"+tSchema.getText(); String uName = tUsername.getText(); char[] l = pPassword.getPassword(); System.out.println(l); String password= l.toString(); System.out.println(host+uName+l); con = DriverManager.getConnection(host, uName, password); System.out.println(host+uName+password); } catch (SQLException | ClassNotFoundException ex) { JOptionPane.showMessageDialog(this, ex.getMessage()); } }

  • Multi-user job/task tracking/queue software

    - by Bmsgaffer86
    Background: I test and repair electronic products with a team. There are many 'jobs' going through my lab at any point in time. It is getting difficult to track whats coming in and going out because I don't do every test or repair myself. Target: User can enter a job when they drop it off in my lab, and it will appear on the master list or queue. Needs to have priorities and due dates that can be adjusted by users. Ideally this would be web based and open-source, but I am flexible. Dream: A large monitor displaying a list of jobs in the master queue with details. This is very optional though, and would be in the best case scenario. I have done MANY hours of Google-ing and I am not sure if I have been using the right terminology, but I have not found anything that is simple enough to stand alone yet complex enough to be multi-user based. I am mildly proficient in VB, and have the drive to piece anything together that I have to. I am open to ANY help or suggestions.

  • Can somebody please explain this recursive function for me?

    - by capncoolio
    #include <stdio.h> #include <stdlib.h> void reprint(char *a[]) { if(*a) { printf("%d ",a); reprint(a+1); printf("%s ",*a); } } int main() { char *coll[] = {"C", "Objective", "like", "don't", "I", NULL}; reprint(coll); printf("\n"); return EXIT_SUCCESS; } As the more experienced will know, this prints the array in reverse. I don't quite understand how! I need help understanding what reprint(char *a[]) does. I understand pointer arithmetic to a degree, but from inserting printf's here and there, I've determined that the function increments up to the array end, and then back down to the start, only printing on the way down. However, I do not understand how it does this; all I've managed to understand by looking at the actual code is that if *a isn't NULL, then call reprint again, at the next index. Thanks guys!

  • Removing random object from parent CCprite

    - by Natty
    probably this is a simple problem to solve, since I'm quite new. I have a scene with a waiter holding a tray of food (the food is a random CCSprite choosen from an array) each time he comes onscreen he holds a new piece of food (the user touches the food and the waiter walks off to return again with a new piece of food however I cant seem to delete the old peice of food from the screen as it says the child is already added... any help would be great -(id) init { ///other code then... waiterOnSCreen = [CCSprite spriteWithSpriteFrameName:@"CatUP.png"]; waiterOnSCreen.position = ccp(CatOffSCreenPosX, catXpos); [self addChild:waiterOnSCreen z:0]; //moving the waiter // the random food sprite is added later to the waiter // [waiterOnSCreen addChild:myRandomSprite]; } -(void)LoadRandomFood { ///I make my array here then... int i = arc4random() % [RandomFood count]; myRandomSprite = (CCSprite *)[RandomFood objectAtIndex:i]; //waiterOnSCreen is a CCSprite added on the init [waiterOnSCreen addChild:myRandomSprite]; myRandomSprite.position=ccp(290,220); myRandomSprite.tag = RandomFoodTag; } } later in if(CGRectContainsPoint(waiterOnSCreen.boundingBox, location)) { //trying to remove the food here //Ive already tried to remove the sprite using [self removeChildByTag:RandomeObjectTag]; //and also CCSprite *wantedSprite = (CCSprite *)[self getChildByTag:RandomFoodTag]; [wantedSprite removeFromParentAndCleanup:YES]; } }

  • Using an objects date (without time) for a table header instead of an objects date and time (iphone)

    - by billywilliamton
    I've been working on an iphone project and have run into an issue. Currently In the table view where it displays all the objects, I use headers based on the objects datePerformed field. The only problem is that my code apparently creates a header that contains both the date and time resulting in objects not being grouped solely by their date as I intended, but rather based on their date and time. I'm not sure if it matters, but when an object is created I use a date picker to pick the date, but not the time. I was wondering if anyone could give me any suggestions or advice. Here is the code where i set up the fetchedResultsController - (NSFetchedResultsController *)fetchedResultsController { if (fetchedResultsController != nil) { return fetchedResultsController; } // Create and configure a fetch request with the Exercise entity. NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Exercise" inManagedObjectContext:managedObjectContext]; [fetchRequest setEntity:entity]; // Create the sort descriptors array using date and name NSSortDescriptor *dateDescriptor = [[NSSortDescriptor alloc] initWithKey:@"datePerformed" ascending:NO]; NSSortDescriptor *nameDescriptor = [[NSSortDescriptor alloc] initWithKey:@"name" ascending:YES]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:dateDescriptor, nameDescriptor, nil]; [fetchRequest setSortDescriptors:sortDescriptors]; // Create and initialize the fetch results controller NSFetchedResultsController *aFetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:managedObjectContext sectionNameKeyPath:@"datePerformed" cacheName:@"Root"]; self.fetchedResultsController = aFetchedResultsController; fetchedResultsController.delegate = self; // Memory management calls [aFetchedResultsController release]; [fetchRequest release]; [dateDescriptor release]; [nameDescriptor release]; [sortDescriptors release]; return fetchedResultsController; } Here's where I set up the table header properties - (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section { // Display the exercise' date as section headings. return [[[fetchedResultsController sections] objectAtIndex:section] name]; } Any suggestions welcome. Thanks for your time. -Billy Williamton

  • Java: How ArrayList memory management

    - by cka3o4nik
    In my Data Structures class we have studies the Java ArrayList class, and how it grows the underlying array when a user adds more elements. That is understood. However, I cannot figure out how exactly this class frees up memory when lots of elements are removed from the list. Looking at the source, there are three methods that remove elements: [code] public E remove(int index) { RangeCheck(index); modCount++; E oldValue = (E) elementData[index]; int numMoved = size - index - 1; if (numMoved 0) System.arraycopy(elementData, index+1, elementData, index, numMoved); elementData[--size] = null; // Let gc do its work return oldValue; } public boolean remove(Object o) { if (o == null) { for (int index = 0; index < size; index++) if (elementData[index] == null) { fastRemove(index); return true; } } else { for (int index = 0; index < size; index++) if (o.equals(elementData[index])) { fastRemove(index); return true; } } return false; } private void fastRemove(int index) { modCount++; int numMoved = size - index - 1; if (numMoved 0) System.arraycopy(elementData, index+1, elementData, index, numMoved); elementData[--size] = null; // Let gc do its work } {/code] None of them reduce the datastore array. I even started questioning if memory free up ever happens, but empirical tests show that it does. So there must be some other way it is done, but where and how? I checked the parent classes as well with no success.

  • Custom punctuation function making script run over the php's 60s runtime limit

    - by webmasters
    I am importing allot of product data from an XML file (about 5000 products). When I run the script I can make it work in about 10-12 seconds. Now, when I add this punctuation function which makes sure each product description ends with a punctuation sign, the code runs until the php 60 seconds loadtime on my server but I'm not getting any errors. I have error reporting turned on. I just get a final error that the script could not load in 60 seconds. The question is, looking at this function, is it that resource consuming? What can I do to make it faster? function punctuation($string){ if(strlen($string) > 5){ // Get $last_char $desired_punctuation = array(".",",","?","!"); $last_char = substr($string, -1); // Check if $last_char is in the $desired_punctuation array if(!in_array($last_char, $desired_punctuation)){ // strip the $mytrim string and get only letters at the end; while(!preg_match("/^[a-zA-Z]$/", $last_char)){ $string = substr($string, 0, -1); $last_char = substr($string, -1); } // add "." to the string $string .= '.'; } } return $string; } If the function is ok, the long runtime must come from something else which I'll have to discover. I just want your input on this part.

  • How to start x-axis labels(dates) from 0th position without using set_range(..)

    - by Rishi2686
    Hi there, First of all, I am really a newbie for flash charts. I have problem in using it. I am developing an app which gets values from database for chart. I have a line on chart, there are dates on x-axis starting from 0th position. I have dates 03-06-2010 and 05-06-2010 right now and may increase in future. When I set range of 1 month i.e 1st jun to 30th jun , it does not show lines but show values on y-axis. When I use range, i am not able to pass array of above two dates from database to chart, and viceversa. Here is my code-snippet can you give some hint. $x = new x_axis(); $x->set_range( mktime(0, 0, 0, 6, 1, date('Y')), // <-- min == 1st Jan, this year mktime(0, 0, 0, 6, 16, date('Y')) // <-- max == 31st Jan, this year ); $x->set_steps(86400); $labels = new x_axis_labels(); $labels->text('#date: jS, M Y#'); $labels->set_steps(86400); $labels->visible_steps(1); $labels->rotate(90); //$labels->set_labels($data_4); // date_4 is array of database values $x->set_labels($labels);

  • JSONP not firing on IPad

    - by Gemtag
    After trying everything possible I've come to the conclusion this is an issue with IPad Safari. This works in FF, IE, Chrome, and Safari on MacBook. Below is my dumbed-down code. I have 2 separate JSONP calls, This first one works in all browsers including IPad. This simply calls a function based on a blur event $('#gender').blur(function() { reTarget(); }); function reTarget() { $.getJSON("http://host.com/Jsonpgm?jsoncallback=?", function() { } ); } Below is where things break. On the same page as the above code is the following, which calls a function based on a submit button click. $(':submit').bind('click', function(event) { if (checkThis() == false) { return false; }; }); $('form').bind('submit', function(event) { if (checkThis() == false) { return false; }; }); function checkThis() { $.getJSON("http://host.com/Jsonpgm.aspx?jsoncallback=?", function() { } ); } This code will not fire. I've put alerts right before it and they fire. I look at the web logs and there is no entry for this json call. I would take any suggestions on this. At this point I fear it's a problem with firing jsonp from a submit event.

  • How to randomly assign a partner?

    - by David
    I asked a question some time ago about creating a random circular partner assignment using php and mysql. This is a related issue. I am working from the following code to try to give two users new, randomly selected partners: $q = "SELECT user_id FROM users WHERE partner='$quit_partner' AND status='1'"; $r = mysqli_query ($dbc, $q) or trigger_error("Query: $q\n<br />MySQL Error: " . mysqli_error($dbc)); while ($row = mysqli_fetch_array($r)) { $users[] = $row[0]; } $current = end($users); $partners = array(); foreach ($users as $user) { $partners[$user] = $current; $current = $user; $q = "UPDATE users SET partner='{$partners[$user]}' WHERE user_id='{$user}'"; mysqli_query ($dbc, $q) or trigger_error("Query: $q\n<br />MySQL Error: " . mysqli_error($dbc)); } Basically, a particular user (lets say user #4) quits the activity, leaving multiple other users without a partner (hypothetically, users # 5,6,7). I need to find out who those users are, hence the first query. Once I find them, I throw them into an array. Then comes the difficult part. I want those newly partnerless users (5,6,7) to be randomly assigned new partners from everyone in the table. The current code is flawed in that it only assigns the newly partnerless users eachother. Thanks for your help.

  • Compression Program in C

    - by Delandilon
    I want to compress a series of characters. For example if i type Input : FFFFFBBBBBBBCCBBBAABBGGGGGSSS (27 x 8 bits = 216 bits) Output: F5B7C2B3A2B2G5S3 (14 x 8 bits = 112bits) So far this is what i have, i can count the number of Characters in the Array. But the most important task is to count them in the same sequence. I can't seem to figure that out :( Ive stared doing C just a few weeks back, i have knowledge on Array, pointers, ASCII value but in any case can't seem to count these characters in a sequence. Ive try a bit of everything. This approach is no good but it the closest i came to it. #include <stdio.h> #include <conio.h> int main() { int charcnt=0,dotcnt=0,commacnt=0,blankcnt=0,i, countA, countB; char str[125]; printf("*****String Manipulations*****\n\n"); printf("Enter a string\n\n"); scanf("%[^'\n']s",str); printf("\n\nEntered String is \" %s \" \n",str); for(i=0;str[i]!='\0';i++) { // COUNTING EXCEPTION CHARS if(str[i]==' ') blankcnt++; if(str[i]=='.') dotcnt++; if(str[i]==',') commacnt++; if (str[i]=='A' || str[i]=='a') countA++; if (str[i]=='B' || str[i]=='b') countA++; } //PRINT RESULT OF COUNT charcnt=i; printf("\n\nTotal Characters : %d",charcnt); printf("\nTotal Blanks : %d",blankcnt); printf("\nTotal Full stops : %d",dotcnt); printf("\nTotal Commas : %d\n\n",commacnt); printf("A%d\n", countA); }

  • Is there any well-known paradigm for iterating enum values?

    - by SadSido
    I have some C++ code, in which the following enum is declared: enum Some { Some_Alpha = 0, Some_Beta, Some_Gamma, Some_Total }; int array[Some_Total]; The values of Alpha, Beta and Gamma are sequential, and I gladly use the following cycle to iterate through them: for ( int someNo = (int)Some_Alpha; someNo < (int)Some_Total; ++someNo ) {} This cycle is ok, until I decide to change the order of the declarations in the enum, say, making Beta the first value and Alpha - the second one. That invalidates the cycle header, because now I have to iterate from Beta to Total. So, what are the best practices of iterating through enum? I want to iterate through all the values without changing the cycle headers every time. I can think of one solution: enum Some { Some_Start = -1, Some_Alpha, ... Some_Total }; int array[Some_Total]; and iterate from (Start + 1) to Total, but it seems ugly and I have never seen someone doing it in the code. Is there any well-known paradigm for iterating through the enum, or I just have to fix the order of the enum values? (let's pretend, I really have some awesome reasons for changing the order of the enum values)...

  • C# What is the best way to determine the type of an inherited interface class?

    - by Martijn
    In my application I work with criterias. I have one base Criteria interface and and other interfaces who inherits from this base interface: ICriteria | | ---------------------- | | ITextCriteria IChoices What I'd like to know is, what is the best way to know what Type the class is? In my code I have a dropdown box and based on that I have to determine the type: // Get selected criteria var selectedCriteria = cmbType.SelectedItem as ICriteria; if (selectedCriteria is IChoices) { //selectedCriteria = cmbType.SelectedItem as IChoices; Doesn't work IChoices criteria = selectedCriteria as IChoices;//cmbType.SelectedItem as IChoices; SaveMultipleChoiceValues(criteria); //_category.AddCriteria(criteria); } else { //ICriteria criteria = selectedCriteria; //cmbType.SelectedItem as ICriteria; if (selectedCriteria.GetCriteriaType() == CriteriaTypes.None) { return; } //_category.AddCriteria(criteria); } _category.AddCriteria(selectedCriteria); selectedCriteria.LabelText = txtLabeltext.Text; this.Close(); My question is, is this the best way? Or is there a better way to achieve this? The chance is big that there are coming more interfaces based on ICriteria.

  • UITableView populating EVERY OTHER launch

    - by Joshmattvander
    I am having a problem that I cant seem to get to the bottom of. In my view did load code, I am creating an array and attempting to populate the table. For some reason it only populates the data on EVERY OTHER time the app is run. I put logs in viewDidLoad which runs as does viewWillAppear and outputs the correct count for the array. Also, the UITableView specicic methods get called when it works and they just don't get called when it doesnt work. I cant figure out the root of this problem. Again this occurrence happens exactly 50% of the time. Theres no dynamic data that could be tripping up or anything. #import "InfoViewController.h" @implementation InfoViewController - (void)viewDidLoad { NSLog(@"Info View Loaded"); // This runs infoList = [[NSMutableArray alloc] init]; //Set The Data //Theres 8 similar lines [infoList addObject :[[NSMutableDictionary alloc] initWithObjectsAndKeys: @"Scrubbed", @"name", @"scrubbed", @"url", nil]]; NSLog(@"%d", [infoList count]); // This shows the count correctly every time [super viewDidLoad]; } -(void) viewWillAppear:(BOOL)animated { NSLog(@"Info Will Appear"); // This Runs } - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { // This WILL NOT RUN when it doesnt work, and DOES show the count when it does run NSLog(@"Counted in numberOfRowsInSection %d", [infoList count]); return [infoList count]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { NSLog(@"ROW"); static NSString *CellIdentifier = @"infoCell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease]; } cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; cell.textLabel.text = [[infoList objectAtIndex:indexPath.row] objectForKey:@"name"]; return cell; } @end

  • Java: How do I implement a method that takes 2 arrays and returns 2 arrays?

    - by HansDampf
    Okay, here is what I want to do: I want to implement a crossover method for arrays. It is supposed to take 2 arrays of same size and return two new arrays that are a kind of mix of the two input arrays. as in [a,a,a,a] [b,b,b,b] ------ [a,a,b,b] [b,b,a,a]. Now I wonder what would be the suggested way to do that in Java, since I cannot return more than one value. My ideas are: - returning a Collection(or array) containing both new arrays. I dont really like that one because it think would result in a harder to understand code. - avoiding the need to return two results by calling the method for each case but only getting one of the results each time. I dont like that one either, because there would be no natural order about which solution should be returned. This would need to be specified, though resulting in harder to understand code. Plus, this will work only for this basic case, but I will want to shuffle the array before the crossover and reverse that afterwards. I cannot do the shuffling isolated from the crossover since I wont want to actually do the operation, instead I want to use the information about the permutation while doing the crossover, which will be a more efficient way I think.

    My iPhone app has the following problem: Freshly installed, when I read out my "Play Sound" preference with the following code: defaults = [NSUserDefaults standardUserDefaults]; NSLog(@"Play Sounds? %d", [defaults boolForKey:@"play_sounds_preference"]); The setting always reads out as false, even though the default setting is set to true. Any ideas? Here is my Root.plist: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>StringsTable</key> <string>Root</string> <key>PreferenceSpecifiers</key> <array> <dict> <key>Type</key> <string>PSGroupSpecifier</string> <key>Title</key> <string>General Settings</string> </dict> <dict> <key>Type</key> <string>PSToggleSwitchSpecifier</string> <key>Title</key> <string>Sounds</string> <key>Key</key> <string>play_sounds_preference</string> <key>DefaultValue</key> <true/> </dict> </array> </dict> </plist> When the user opens the Settings.app and navigates to my app's name, THEN the setting reads out as true, even if the user doesn't change anything.

  • Planning a programming project by example (C# or C++)

    - by Lunan
    I am in the last year of undergraduate degree and i am stumped by the lack of example in c++ and c# large project in my university. All the mini project and assignment are based on text based database, which is so inefficient, and console display and command, which is frustrating. I want to develop a complete prototype of corporate software which deals in Inventory, Sales, Marketing, etc. Everything you would usually find in SAP. I am grateful if any of you could direct me to a books or article or sample program. Some of the question are : How to plan for this kind of programming? should i use the concept of 1 object(such as inventory) have its own process and program and have an integrator sit for all the program, or should i integrate it in 1 big program? How to build and address a database? i have little bit knowledge in database and i know SQL but i never address database in a program before. Database are table, and how do you suppose to represent a table in a OOP way? For development type, which is better PHP and C++ or C# and ASP.NET? I am planning to use Web Interface to set form and information, but using a background program to handle the compute. .NET is very much integrated and coding should be much faster, but i really wonder about performance if compared to PHP and C++ package thank you for the info

  • retrieve only sub-pages (wordpress)

    - by Radek
    I want to list all sub-pages only one level though of one particular page. I was reading Function Reference/get pages and thought that $pages = get_pages( array( 'child_of' => $post->ID, 'parent' => $post->ID)) ; will do the trick but it is not working. It lists all pages on the same level like the page I call that code from. If I omit parent option I will get all pages even with sub-pages that I want. But I want only sub-pages. The whole function is like function about_menu(){ if (is_page('about')){ $pages = get_pages( array( 'child_of' => $post->ID, 'parent' => $post->ID)) ; foreach($pages as $page) { ?> <h2><a href="<?php echo get_page_link($page->ID) ?>"><?php echo $page->post_title ?></a></h2> <?php } } } and mine is second one

  • C# xml serializer - serialize derived objects

    - by gln
    Hi, I want to serialize the following: [Serializable] [DefaultPropertyAttribute("Name")] [XmlInclude(typeof(ItemInfo))] [XmlInclude(typeof(ItemInfoA))] [XmlInclude(typeof(ItemInfoB))] public class ItemInfo { private string name; [XmlArray("Items"), XmlArrayItem(typeof(ItemInfo))] private ArrayList arr; private ItemInfo parentItemInfo; } [Serializable] [XmlInclude(typeof(ItemInfo))] [XmlInclude(typeof(ItemInfoA))] [XmlInclude(typeof(ItemInfoB))] public class ItemInfoA : ItemInfo { ... } [Serializable] [XmlInclude(typeof(ItemInfo))] [XmlInclude(typeof(ItemInfoA))] [XmlInclude(typeof(ItemInfoB))] public class ItemInfoB : ItemInfo { ... } The class itemInfo describes a container which can hold other itemInfo objects in the array list, the parentItemInfo describes which is the parent container of the item info. Since ItemInfoA and ItemInfoB derive from ItemInfo they can also be a member of the array list and the parentItemInfo, therefore when trying to serialize these objects (which can hold many objects in hierarchy) it fails with exception can't generate the xml file - innerexception. My question is: What attributes do I need to add the ItemInfo class so it will be serializable? Note: the exception is only when the ItemInfo[A]/[B] are initialized with parentItemInfo or the arrayList. Help please! Thanks!

  • Zend Metadata Cache in file

    - by Matthieu
    I set up a metadata cache in Zend Framework because a lot of DESCRIBE queries were executed and it affected the performances. $frontendOptions = array ('automatic_serialization' => true); $backendOptions = array ('cache_dir' => CACHE_PATH . '/db-tables-metadata'); $cache = Zend_Cache::factory( 'Core', 'File', $frontendOptions, $backendOptions ); Zend_Db_Table::setDefaultMetadataCache($cache); I can indeed see the cache files created, and the website works great. However, when I launch unit tests, or a script of the same application that perform DB queries, I end up with an error because Zend couldn't read the cache files. This is because in the website, the cache files are created by the www user, and when I run phpunit or a script, it tries to read them with my user and it fails. Do you see any solution to that? I have some quickfix ideas but I'm looking for a good/stable solution. And I'd rather avoid running phpunit or the scripts as www if possible (for practical reasons).
