• How do I make a multiple file upload?

  - by Bluemagica

  I am trying to make a multiple image uploader. The file upload fields are being added in the form dynamically using jquery. I tried making an array of the fields since I don't want to have a hidden field. so my generated upload fields look like <input type="file" id="img0" name="img[]"/> <input type="file" id="img1" name="img[]"/> <input type="file" id="img2" name="img[]"/> ..... .. And on the php side I did something like if(isset($_FILES['img'])) { foreach($_FILES['img'] as $k=>$v) { if($v!="") { uploadImage($k,0,0,0,"content/gallery/"); } } } Now I know I am way too wrong, since in that code I am looping through the 'img' file's properties instead of all images....but I have no idea how to fix this. PS: uploadImage is a function I wrote which expects the file input field's name as the first parameter.

• How to test obtaining a list of files within a directory using RSpec?

  - by John Topley

  I'm pretty new to the world of RSpec. I'm writing a RubyGem that deals with a list of files within a specified directory and any sub-directories. Specifically, it will use Find.find and append the files to an Array for later output. I'd like to write a spec to test this behaviour but don't really know where to start in terms of faking a directory of files and stubbing Find.find etc. This is what little I have so far: it "should return a list of files within the specified directory" do end Any help much appreciated!

• why assert_equal() in Ruby on Rails sometimes seem to compare by Identity and sometimes by value?

  - by Jian Lin

  it was very weird that yesterday, I was do an integration test in Rails and assert_equal array_of_obj1, array_of_obj2 # obj1 from db, obj2 created in test and it failed. The values shown inside the array and objects were identical. If I change the test to assert array_of_obj1 == array_of_obj2 Then it will pass. But today, the first test actually passed. What reason could it be? Is assert_equal always using == or .equal? in Rails 2.2 or 2.3.5?

• Creating a PHP web page that enables you to reboot the server in Linux?

  - by Stuart

  I want to create a web page that allows the user to initiate a reboot on the linux server. Obviously this would only be avaliable for system admins and would also be controlled by using iptables. Below is a sample of code that I was thinking of using but I wanted to know if there is another way to do this and how also to use this in a web page? Also is there any thing else that I should consider? $command = "cat $pass | su -c 'shutdown -r now'"; $output = array(); try{ echo shell_exec($command); exec($command, $output); system($command, $output); } catch(Exception $e) { print "Unable to shutdown system...\n"; } foreach ($output as $line) { print "$line<br>"; } Thanks in advance.

• Should Perl's opendir always return . and .. first?

  - by ojblass

  opendir MYDIR, "$dir"; my @FILES = readdir MYDIR; closedir MYDIR; It appears that 99.9 % of the time the first two entries in the array are always “.” and “..”. Later logic in the script has issues if it is not true. I ran into a case where the directory entries appeared later. Is this indicative of the file system being corrupt or something else? Is there a known order to what opendir returns?

• UITableViewController executes delate functions before network request finishes

  - by user1543132

  I'm having trouble trying to populate a UITableView with the results of a network request. It seems that my code is alright as it works perfectly when my network is speedy, however, when it's not, the function - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath- still executes, which results in a bad access error. I presume that this is because the array that the aforesaid function attempts to utilize has not been populated. This brings me to my question: Is there anyway that I can have the UITableView delegate methods delayed to avoid this? - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"AlbumsCell"; //UITableViewCell *basicCell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath]; AlbumsCell *cell = (AlbumsCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (!cell) { **// Here is where the Thread 1: EXC_BAD_ACCESS (code=2 address=0x8)** cell = [[[AlbumsCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } Album *album = [_albums objectAtIndex:[indexPath row]]; [cell setAlbum:album]; return cell; }

• using a tileset with canvas

  - by Anonymous

  Yeah so I'm lost from the get-go. Alright let's say I have a big image with every tile for a 2D top-down RPG game. They're all the same width and everything. What I don't know is how would I save every individual tile from that image to their own image data for use on the canvas? Basically I want to take a big image with all my tiles, choose squares throughout it to make images out of the tiles, and store each image as a variable in an array. So, how would I do this?

• Parse boolean values in strings for use with Function.apply

  - by as3cmdline

  I'm using String.split to parse a command line string into an array of strings. The result is then used to call a function using the Function.apply API. If apply(null, ["17"]) is called with this function: static function test(foo:int):void { trace(foo, typeof(foo)); } it works as expected (output: 17 number). However, calling apply(null, ["false"]) or apply(null, ["0"]) with this function: static function test(foo:Boolean):void { trace(foo, typeof(foo)); } does not work (expected output: false Boolean; actual output: true Boolean). Is there a way to make it recognize "true" and "false" (or anything else) as Boolean values, just like it does with numerical strings? Ideally "true" and "false" should also remain valid string values.

• (C++) While reading a file (ifstream), is there any way to direct it to make a new line?

  - by Enzo

  While reading a file (ifstream), is there any way to direct it to make a new line? For instance, I would like for THIS to happen: myfilearray[1]array[2]endl; Obviously, the "endl" just isn't allowed. Is there another way to do this? Edit---thanks for the quick responses guys! From a text file, I'm trying to store two strings from that file into arrays and then do the same with the next line (or until I desire, using a for loop) Using strings is important to me as it will make my future program a lot more flexible.

• perl negative look behind with groupings

  - by user1539348

  I have a problem trying to get a certain match to work with negative look behind example @list = qw( apple banana cherry); $comb_tlist = join ("|", @tlist); $string1 = "include $(dir)/apple"; $string2 = "#include $(dir)/apple"; if( string1 =~ /^(?<!#).*($comb_tlist)/) #matching regex I tried, works The array holds a set of variables that is matched against the string. I need the regex to match $string1, but not $string2. It matches $string1, but it ALSO matches $string2. Can anyone tell me what I am attempting wrong here. Thanks!

• Swap byte 2 and 4 from integer

  - by czar x

  I had this interview question - Swap byte 2 and byte4 within an integer sequence. Integer is a 4byte wide i.e. 32 bits My approach was to use char *pointer and a temp char to swap the bytes. For clarity i have broken the steps otherwise an character array can be considered. unsigned char *b2, *b4, tmpc; int n = 0xABCD; b2 = &n; b2++; b4 = &n; b4 +=3; ///swap the values; tmpc = *b2; *b2 = *b4; *b4 = tmpc; Any other methods?

• Android ListView Item Visibility

  - by user1478754

  I'm trying to create a screen that displays multiples items. For this, I've created a listview but I'm not sure how to approach how to add/remove items from it. Since I'm using custom listview items, I've created my own listadapter but now I need a way to add items on a button click. Is there a way to create listview that can take an indefinite amount of items (instead of passing it in an fixed length array of View objects)? Also what's the best way to remove items from listviews? setVisibility?

• Wordpress SQL_CALC fix causes PHP error

  - by ok1ha

  I'm looking for some followup on an older topic for Wordpress where SQL_CALC was found to slow things down when you have a large DB in Wordpress.

• ruby: sum corresponding members of two arrays

  - by jjnevis

  I've got two (or more) arrays with 12 integers in each (corresponding to values for each month). All I want is to add them together so that I've got a single array with summed values for each month. Here's an example with three values: [1,2,3] and [4,5,6] = [5,7,9] The best I could come up with was: [[1,2,3],[4,5,6]].transpose.map{|arr| arr.inject{|sum, element| sum+element}} #=> [5,7,9] Is there a better way of doing this? It just seems such a basic thing to want to do.

• Seeking assistance with Escaping Data for MySQL queries

  - by JM4

  Please don't send me a link to php.net referencing mysql_real_escape_string as the only response. I have read through the page and while I understand the general concepts, I am having some trouble based on how my INSERT statement is currently built. Today, I am using the following: $sql = "INSERT INTO tablename VALUES ('', '$_SESSION['Member1FirstName'], '$_SESSION['Member1LastName'], '$_SESSION['Member1ID'], '$_SESSION['Member2FirstName'], '$_SESSION['Member2LastName'], '$_SESSION['Member2ID'] .... and the list goes on for 20+ members with some other values entered. It seems most people in the examples already have all their data stored in an array. On my site, I accept form inputs, action="" is set to self, php validation takes place and if validation passes, data is stored into SESSION variables on page 2 then redirected to the next page in the process (page 3) (approximately 8-10 pages in the whole process). thanks!
