  • Duplicate Blob field with foreach

    - by JGSilva
    I have some fields (blob) where I have uploaded some images. The images display correctly and I can open it without problem in Photoshop for example. I created a button where user can duplicate the product and everything works fine, but when it comes to duplicate the image entry I got some errors, like 1064 and others ones that I can't remember cause I am working 3 days inside this. Because de original product have 3 or more images I select then and gave an foreach. What I notice when a print de blob is that in the end it eats the next array, like if don't have an end. In other words, the next item got inside that utf-8 character in the print. That gave me some clue. The next approach was to save it in somewhere, and reupload it. The problem is that only the first one works. When I download the image saved, it opens normally so, it is not a saving in disk problem. When I gave a print in the $result, the same happens, is like the image is hungry and ate the next one. Here is the code. Notice = I created the [$count] to see if was not an rewrite in array error. Even tried to , in beging of the foreach, kind of clean the vars… $count=0; foreach ($original_image as $key => $val) { $count++; //$arquivo = ''; //$image = ''; //$file = ''; //$this->image = ''; //$return = ''; $arquivo[$count] = $val['pi_id'].'.'.$val['pi_type']; $image[$count] = $caminho_url.$arquivo[$count]; if (file_exists($image[$count])) { $this->image = Image::factory($image[$count]); $this->image->save($image[$count]); $file[$count]=mysql_real_escape_string(addslashes(fread(fopen($image[$count], "r"), filesize($image[$count])))); $return[$count] = Product::add_image($id_prod, $file[$count], $val['pi_type'],$val['pi_main']); }else { die('no'); } }

  • PHP Captcha without session

    - by Anton N
    Ok, here is an issue: in the project i'm working on, we can't rely on server-side sessions for any functionality. The problem is that common captcha solutions from preventing robotic submits require session to store the string to match captcha against. The question is - is there any way to solve the problem without using sessions? What comes to my mind - is serving hidden form field, containing some hash, along with captcha input field, so that server then can match these two values together. But how can we make this method secure, so that it couldn't be used to break captcha easily.

  • need help on php if statement

    - by user225269
    <?php if (!isset($_SESSION['loginAdmin']) || ($_SESSION['loginAdmin'] == '')) { header ("Location: loginam.php"); } else { include('head2.php'); } if (!isset($_SESSION['login']) || ($_SESSION['login'] == '')) { header ("Location: login.php"); } else { include('head3.php'); } ?> I'm really stuck at this problem. What I want to do is to be able to redirect the user to another page base on the information entered. My problem is: if this statement is true: else { include('head3.php'); } This one would also be true: if (!isset($_SESSION['loginAdmin']) || ($_SESSION['loginAdmin'] == '')) { header ("Location: loginam.php"); } Leading me to the login page whether I'm admin or just ordinary user. Is it possible two separate the two if statements so that if this is true: else { include('head3.php'); } Then this statement shouldn't get in the way and redirect me back to the login page: if (!isset($_SESSION['loginAdmin']) || ($_SESSION['loginAdmin'] == '')) { header ("Location: loginam.php"); }

  • iPhone - Cannont access to an IBOutlet (nil valued)

    - by Oliver
    Hello, I have a problem acessing a IBOutlet. I have a NIB inside which there is a tableview, a toolbar and an UILabel (encasulated into a view). The controller (that is the file's owner) is defined as : @interface ChoixPeriodeController : UIViewController <UITableViewDelegate> { IBOutlet UILabel* __periodeInitialeLabel; } @property(nonatomic, retain) UILabel* periodeInitialeLabel; - (void) setSelectedPeriode:(Tache_TypePeriode)typePeriode; In the .m file, this function is called by the parent window to init the Label : - (void) setSelectedPeriode:(Tache_TypePeriode)typePeriode { NSMutableString* tmpString = [NSMutableString string]; [tmpString appendFormat:bla bla bla;....]; self.periodeInitialeLabel.text = tmpString; } Into this function, I can see that self.periodeInitialeLabel is at nil. I can't see why ? Everything is connected into IB... Do you see what can be the problem ?

  • What are the most likely reasons an application would fail on only one of my servers?

    - by Rising Star
    I have several servers to test new code on. I primarily push out asp.NET web applications. Last week, I had an issue where I installed a newly developed web application on three servers. The three servers all run in separate environments. The application worked fine on two of them, but consistently crashed on the third server with each web request. The problem was eventually traced to an in-house developed .dll file being out of date on the third server. I'm certain that this kind of thing happens all the time. However, there are numerous things that could go wrong to cause this kind of behavior. I spent quite a bit of time tracing this problem. I would like to make a list of things to be suspicious of next time this happens? What are the most likely reasons that a web application would crash on one of my servers while identical code runs fine on another server.

  • Storing datetime in database?

    - by Curtis White
    I'm working on a blog and want to show my posts in eastern time zone. i figured that storing everything UTC would be the proper way. This creates a few challenges though: I have to convert all times from UTC to Eastern. This is not a biggie but adds a lot of code. And the "biggie" is that I use a short-date time to reference the posts by passing in a query, ala blogger. The problem is that there is no way to convert the short date time to the proper UTC date because I'm lacking the posted time info. Hmm, any problem to just storing all dates in eastern time? This would certainly make it easier for the rest of the application but if I needed to change time zones everything would be stored wrong.

  • CodeIgniter Validation in Library does not accept callback.

    - by Lukas Oppermann
    Hey guys, my problem is the following: I am writing a login library. This library has a function _validation() and this uses the validation library to validate the data. With using normal validation methods it works just fine, but using a callback function just does not work. It is not called. I call it like this. $this->CI->form_validation->set_rules('user', 'Username', 'required|callback__check_user'); The functions name is _check_user and it uses the username _check_user($user). The function itself works fine and I can also call it in the class ($this-_check_user('username')) with a working result. I am guessing, there might be a problem because I am not workin in a controller so I have a CI instance $this-CI instead of just the original instance $this- Does anyone have a clue how to fix this? Thanks in advance.

  • Manipulating the case of the build macros in Visual Studio: $(TargetDir)

    - by miked
    I've come across a weird problem today in Visual Studio 2005. If I create a new configuration "NewConfiguration" for one of my projects. The output directory referred to by the project in $(TargetDir) is "/path/to/build/area/newconfiguration". Note the loss of capital letters, I'd expect it to be in "/path/to/build/area/NewConfiguration". In another project that I created yesterday, the capital letters are there. Normally this would be a problem, but it's part of a fairly complicated build system where some of it's on unix and we need to worry about case sensitive filename. Does anyone know where the source string for the Visual Studio macros like $(TargetDir) are stored so that I can get the case to be consistent and match what we need for our build system?

  • n*n blocks and polygons

    - by OSaad
    Hi, this is actually meant to be for a function called roipoly in matlab but it can be considered a general case problem. Roipoly is a function which lets u select a polygon over an image, and returns a binary mask where u can use it to get indices of the desired polygon. (It is just a normal polygon after all). My application (K-Nearest Neighbor) requires that i make n*n blocks out of the data i have (the polygon), i.e. If i have a polygon (a road or a piece of land), i want a n*n square moving over it while avoiding intersection with edges and putting those n*n pixels into some variable. This problem would be a lot easier if i had all my shapes in the form of rectangles, but that unfortunately isn't the case. I might have something going diagonal, circular or just irregular.

  • Browser Compatablitiy, Support, Modern Browsers and older Versions.

    - by smoop
    This is a question to all web-developers working in the industry more than a few years. Today the server guy at my work told me that his browser didnt render a google font I used on a site properly, so I checked his browser - it was firefox 3.5. (google font Raleway).. This made me think.. I know for some of our sites its a requirement to support IE6 (larger corperate sites) but for the rest (personal sites) should I be looking at developing for all incrments of firefox, chrome, IE and safari???? Does your company still support IE6? Does your company support previous versions of modern browsers or just the latest ones? and finally, has anyone else had this problem with FF 3.5 and Google Hosted font Raleway..(the font displays extra extra thing so the font is almost unreadable) If anyones interested I found a working solution to my font problem here: http://www.jshsolutions.net/google-webfonts-cross-browser-fix-howto/ Sam

  • openmp vs opencl for computer vision

    - by user1235711
    I am creating a computer vision application that detect objects via a web camera. I am currently focusing on the performance of the application My problem is in a part of the application that generates the XML cascade file using Haartraining file. This is very slow and takes about 6days . To get around this problem I decided to use multiprocessing, to minimize the total time to generate Haartraining XML file. I found two solutions: opencl and (openMp and openMPI ) . Now I'm confused about which one to use. I read that opencl is to use multiple cpu and GPU but on the same machine. Is that so? On the other hand OpenMP is for multi-processing and using openmpi we can use multiple CPUs over the network. But OpenMP has no GPU support. Can you please suggest the pros and cons of using either of the libraries.

  • Eager loading in EF1.0

    - by Dave Swersky
    I have a many-to-many relationship: Application - Applications_Servers - Server This is set up in my Entity Data Model and all is well. My problem is that I'd like to eager-load the whole graph of Applications so that I have an IEnumerable<Applications>, each Application member populated with the Servers collection associated by the many-to-many relationship. Normally this wouldn't be a problem, but according to my research there must be a navigation property between Application and Server. This is not the case for me because my Applications_Servers join table has more in it than just the two keys. Therefore, there is no navigation property directly between Application and Server, and this doesn't work: var apps = (from a in context.Application.Include("Server") select a).ToList(); I get an error saying there is no navigation property on Application called "Server", and that's correct, there is none. How do I write the query to eager-load my Applications with their Servers in this case?

  • How to practically customize IE context menu?

    - by bionicoder
    I need to add one menu item in IE context menu. It is similar with Google customized context menu "Search Google for xxx" when you right click on IE. I did a research and found that overriding IDocHostUIHandler::ShowContextMenu in a IE BHO can customized IE context menu. The sample project can be found in Popup blocker project published in codeproject. It works well and is easy to implement. However this approach has a problem. The problem is it will conflict with other add-ons' context menu customization per MSDN. In MSDN Internet Explorer Center forum, there are some discussions about this topic. However there is not a proper implementation posted. If anybody has experience on this, please share your idea. Thanks!

  • Can I send a ESC d command to a POS printer from perl?

    - by Bradleyb
    I have a Star TSP100 printer and I'm having few problems with it really. My problem is that I'm not as familiar with programming as I should be - but I'm learning! The programmers reference for the Star printer says that if I send a ESC d to the printer - that will activate the built-in cutter - which I would like to do very much. My problem is that I have no idea how to send an escape code like that from within PERL - if it's even possible. I really appreciate any advice on this one.
