  • how to get the value of an php array in jQuery

    - by user1933824
    i have a PHP code that will obtain the total images of a certain website via CURL, and put it inside an PHP loop. $z=1; for ($i=0;$i<=sizeof($images_array);$i++) { ....<img src = "$images_array[$i]" id="$z"> .. $z++; } a user can then scan through the array with a prev/next button and the current image being shown will be displayed in my $('$current_image').val(1); $.post("curl_fetch.php?url="+ extracted_url, { }, function(response){ $('#loader').html($(response).fadeIn('slow')); $('#current_image').val(1); // insert loop value in .val() when i click a button, i want to get the value of the array, and not the loop value $(function() { $(document).on('click','.submit', function () { var img = $('#current_image').val(); //get the array value, not the loop value alert(img); });}); now, how do i properly get the array value in my $('#current_image').val(1); in Jquery.

  • What are some ways to accomplish a dynamic array?

    - by Ted
    I'm going to start working on a new game and one of the things I'd like to accomplish is a dynamic array sort of system that would hold map data. The game will be top-down 2d and made with XNA 4.0 and C#. You will begin in a randomized area which will essentially be tile based. As such a 2 dimensional array would be one way to accomplish this by holding numerical values which would correspond to a list of textures and that would be how it would draw this randomly created map. The problem is I would kind of only like to create the area around where you start and they could venture in which ever direction they wanted to. This would mean I'd have to populate the map array with more randomized data in the direction they go. I could make a really large array and use the center of it and the rest would be in anticipation of new content to be made, but that just seems very inefficient. I suppose when they start a new game I could have a one time map creation process that would go through and create a large randomly generated map array, but holding all of in memory at all times seems also inefficient. Perhaps if there was a way that I'd only hold parts of that map data in memory at one time and somehow not hold the rest in memory. In the end I only need to have a chunk of the map somewhat close to them in memory so perhaps some of you might have suggestions on good ways to approach this kind of randomized map and dynamic array problem. It wouldn't need to be a dynamic array type of thing if I made it so that it pulled in map data nearby that is needed and then once off the screen and not needed it could somehow get rid of that memory that way I wouldn't have a huge array taking up a bunch of memory.

    I have something like this: var test = {}; function blah() { test[2] = 'filled'; } console.log(test); //result test -> 2:"filled" console.log(test[2]); //result undefined I don't understand why I'm getting 'undefined' in the second instance when according to the first instance, the property of that object clearly exists! Does anyone have any ideas? Thanks

  • Advance Query with Join

    - by user1462589
    I'm trying to convert a product table that contains all the detail of the product into separate tables in SQL. I've got everything done except for duplicated descriptor details. The problem I am having all the products have size/color/style/other that many other products contain. I want to only have one size or color descriptor for all the items and reuse the "ID" for all the product which I believe is a Parent key to the Product ID which is a ...Foreign Key. The only problem is that every descriptor would have multiple Foreign Keys assigned to it. So I was thinking on the fly just have it skip figuring out a Foreign Parent key for each descriptor and just check to see if that descriptor exist and if it does use its Key for the descriptor. Data Table PI Colo Sz OTHER 1 | Blue | 5 | Vintage 2 | Blue | 6 | Vintage 3 | Blac | 5 | Simple 4 | Blac | 6 | Simple =================================== Its destination table is this =================================== DI Description 1 | Blue 2 | Blac 3 | 5 4 | 6 6 | Vintage 7 | Simple ============================= Select Data.Table Unique.Data.Table.Colo Unique.Data.Table.Sz Unique.Data.Table.Other ======================================= Then the dual part of the questions after we create all the descriptors how to do a new query and assign the product ID to the descriptors. PI| DI 1 | 1 1 | 3 1 | 4 2 | 1 2 | 3 2 | 4 By figuring out how to do this I should be able to duplicate this pattern for all 300 + columns in the product. Some of these fields are 60+ characters large so its going to save a ton of space. Do I use a Array?

  • post__not_in only excluding first post in array

    - by fightstarr20
    I am using two query_posts loops to firstly display a set of posts with a custom field of '2012' and then the second loop to display everything else excluding the posts it returned in the first... <?php if( get_query_var('paged') < 2 ) { ?> <?php query_posts( array( 'post_type' => 'project', 'meta_key' => 'start_date_year', 'meta_value' => '2012' )); $ids = array(); ?> <?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?> <p>This is from Loop 1 - <?php the_title(); ?> - <?php the_id(); ?></p> <?php $ids[] = get_the_ID(); ?> <?php endwhile; endif; wp_reset_query(); ?> <?php } ?> <?php $paged = get_query_var( 'paged' ) ? get_query_var( 'paged' ) : 1; query_posts( array( 'post_type' => 'project', 'post__not_in' => $ids, 'orderby' => title, 'order' => ASC, 'paged' => $paged )); ?> <?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?> <p>This is from Loop 2 - <?php the_title(); ?> - <?php the_id(); ?></p> <?php endwhile; endif; wp_reset_query(); ?> <?php pagination(); ?> For some reason the 'post__not_in' = $ids is only excluding the first post ID in the array, I have print_r the array and it does contain all of the post IDs I want to exlcude. Anyone any ideas why only one ID is being excluded?

  • ArrayIndexOutOfBoundsException double array size

    - by Andy
    I'm going to preface this question with this statement: I know that I can easily handle this problem by reading the amount of lines in a file and making an array that size. I am not allowed to do this. Anyway, here is my question. I need to double my array's size whenever my program encounters an ArrayIndexOutOfBoundsException and then copy all the previous read in information into the larger array. Here is my code public static void main(String[] args) throws IOException { Scanner inScan, fScan = null; int [] A = new int[5]; inScan = new Scanner(System.in); System.out.print("Please enter the file to read from: "); while(true) { try{ String fName = inScan.nextLine(); fScan = new Scanner(new File(fName)); break; } catch (FileNotFoundException ex) { System.out.println("Your file is invalid -- please re-enter"); } } String nextItem; int nextInt = 0; int i = 0; while (fScan.hasNextLine()) { try { nextItem = fScan.nextLine(); nextInt = Integer.parseInt(nextItem); A[i] = nextInt; i++; } catch (NumberFormatException e) { System.out.println("Found an invalid int -- ignored"); } catch (ArrayIndexOutOfBoundsException e) { //double the size of array A until //copy all previous read in information to the larger array } } System.out.println("Here are your " + i + " items:"); for (int j = 0; j < i; j++) { System.out.println(A[j] + " "); } } }

  • Doubt regarding usage of array as a pointer in C

    - by Som
    For eg. I have an array of structs 'a' as below: struct mystruct{ int b int num; }; struct bigger_struct { struct my_struct a[10]; } struct bigger_struct *some_var; i know that the name of an array when used as a value implicitly refers to the address of the first element of the array.(Which is how the array subscript operator works at-least) Can i know do the other way around i.e if i do: some_var->a->b, it should be equivalent to some_var->a[0]->b, am i right? I have tested this and it seems to work , but is this semantically 100% correct?

  • Number of the different elements in an array.

    - by AB
    Is it possible to compute the number of the different elements in an array in linear time and constant space? Let us say it's an array of long integers, and you can not allocate an array of length sizeof(long). P.S. Not homework, just curious. I've got a book that sort of implies that it is possible.

  • Make array from $_POST values

    - by cbarg
    Let's start telling that I'm passing an x amount of variables via post from a form. Let's name them menu_category_1, menu_category_2, ..., menu_category_x, plus, maybe, menu_category_new (I'm using an if empty to check this last one variable). To make things easier I'm also sending the parameter $key (amount of variables starting from 0). Now I need to set them into a new variable $menu_category (array), which is going to be imploded and then update my database. How do I set up that new $menu_category variable to be an array containing all my variables named in the beginning? I was thinking of using a for loop but I can't come up with something useful. Thanks!!!

  • [Python] Best strategy for dealing with incomplete lines of data from a file.

    - by adoran
    I use the following block of code to read lines out of a file 'f' into a nested list: for data in f: clean_data = data.rstrip() data = clean_data.split('\t') t += [data[0]] strmat += [data[1:]] Sometimes, however, the data is incomplete and a row may look like this: ['955.159', '62.8168', '', '', '', '', '', '', '', '', '', '', '', '', '', '29', '30', '0', '0'] It puts a spanner in the works because I would like Python to implicitly cast my list as floats but the empty fields '' cause it to be cast as an array of strings (dtype: s12). I could start a second 'if' statement and convert all empty fields into NULL (since 0 is wrong in this instance) but I was unsure whether this was best. Is this the best strategy of dealing with incomplete data? Should I edit the stream or do it post-hoc?

  • Why does `Array(0,1,2) == Array(0,1,2)` not return the expected result?

    - by soc
    As far as I understand, Scala's == defines the natural equality of two objects. I expected that Array(0,1,2) == Array(0,1,2) compares the natural equality e. g. checks if all elements of the array return true when compared with the corresponding elements of the other array. People told me that Scala's Array is just a Java [] which only compares identity. But Scala's String is also just a Java String but Scala overrides equals to compare natural equality. I wonder why Array's equals method was not overridden, too. Thank you for your thoughts!

  • Selecting value from array results

    - by Swodahs
    Being new to learning PHP I am having trouble with understanding how to select/echo/extract a value from array result a API script returns. Using the standard: echo "<pre>"; print_r($ups_rates->rates); echo "</pre>"; The results returned look like this: Array ( [0] => Array ( [code] => 03 [cost] => 19.58 [desc] => UPS Ground ) [1] => Array ( [code] => 12 [cost] => 41.69 [desc] => UPS 3 Day Select ) [2] => Array ( [code] => 02 [cost] => 59.90 [desc] => UPS 2nd Day Air ) ) If I am only needing to work with the values of the first array result: Code 3, 19.58, UPS Ground --- what is the correct way to echo one or more of those values? I thought: $test = $ups_rates[0][cost]; echo $test; This is obviously wrong and my lack of understanding the array results isn't improving, can someone please show me how I would echo an individual value of the returned array and/or assign it to a variable to echo the normal way?

  • PHP Undefined index - Occuring when the variable has a value in it

    - by Adam
    I have the following code that is being used to successfully upload images: $fileName = $_FILES['file']['name']; $fileSize = $_FILES['file']['size']; $fileType = $_FILES['file']['type']; $fileTmp = $_FILES['file']['tmp_name']; list($origWidth, $origHeight) = getimagesize($fileTmp); The catch is I'm getting an 'Undefined index' on each line. I have print_r($_FILES) just before this code and each array variable exists and I've echo out varibles like $fileName and can see each has a value. Also I have put this before this code block and it makes no difference: $fileName = $fileSize = $fileType = $fileTmp = ''; Any suggestions how I can ensure these variables are defined? thankyou

  • Looping through array values using JQuery and show them on separate lines

    - by user3192948
    I'm building a simple shopping cart where visitors can select a few items they want, click on the "Next" button, and see the confirmation list of things they just selected. I would like to have the confirmation list shown on each line for each item selected. HTML selection <div id="c_b"> <input type="checkbox" value="razor brand new razor that everyone loves, price at $.99" checked> <input type="checkbox" value="soap used soap for a nice public shower, good for your homies, price at $.99" checked> <input type="checkbox" value="manpacks ultimate choice, all in 1, price at $99"> </div> <button type='button' id='confirm'>Next</button> HTML confirmation list <div id='confirmation_list' style='display:none;'> <h2>You have selected item 1</h2> <h2>Your have selected item 2 </h2> </div> JS $(function(){ $('#confirm').click(function(){ var val = []; $(':checkbox:checked').each(function(i){ val[i] = $(this).val(); }); }); }); I ultimately want to replace the words 'Your have selected item 2' in h2s with the values selected from each check box. With the code above I'm able to collect the values of each checkbox into an array val, but having difficulty looping through and displaying them. Any advice would be appreciated.
