  • Generating ul from array with php fails

    - by Toni Michel Caubet
    Given a $files array I am trying to generate a list, like this: <ul class=""> <? for($i=0;$i < count($files); $i++) { $text = str_replace("http://domain.com/files/uploads/", "", $files[$i]); $file = $files[$i]; $notme = sesion()>0 && $obj['id'] != sesion(); ?> <li> <a target="_blank" href="<?=$file?>"><?=$text?></a> <? if($notme){ ?> <span class="add_to_files" data-file="<?=$file?>">Agregar al gestor</span> <? } ?> </li> <? } ?> </ul> This is the output: Please note how the span html is wrong, <ul class=""> <li> <a href="http://domain.com/files/uploads/388400967232883.jpg" target="_blank">388400967232883.jpg</a> <span target="_blank" href="http://domain.com/files/uploads/388400967232883.jpg" url"="" data-file="&lt;a class=" class="add_to_files">http://domain.com/files/uploads/388400967232883.jpg"&gt;Agregar al gestor</span> </li> </ul> Any idea why?

  • C# Implicit array declaration

    - by The.Anti.9
    Basically, I want to be able to use string.Split(char[]) without actually defining a char array as a separate variable. I know in other languages you could do like string.split([' ', '\n']); or something like that. How would I do this in C#?

  • CakePHP - Sorting using HABTM Join Table Field

    - by Ashok
    Hello Cake Gurus, here's my problem: Table1: Posts id - int title - varchar Table2: Categories id - int name - varchar HABTM JoinTable: categories_posts id - int post_id - int category_id - int postorder - int As you can see, the join table contains a field called 'postorder' - This is for ordering the posts in a particular category. For example, Posts: Post1, Post2, Post3, Post4 Categories: Cat1, Cat2 Ordering: Cat1 - Post1, Post3, Post2 Cat2 - Post3, Post1, Post4 Now in CakePHP, $postpages = $this->Post->Category->find('all'); gives me a array like Array ( [0] => Array ( [Category] => Array ( [id] => 13 [name] => Cat1 ) [Post] => Array ( [0] => Array ( [id] => 1 [title] => Post2 [CategoriesPost] => Array ( [id] => 17 [post_id] => 1 [category_id] => 13 [postorder] => 3 ) ) [1] => Array ( [id] => 4 [title] => Post1 [CategoriesPost] => Array ( [id] => 21 [post_id] => 4 [category_id] => 13 [postorder] => 1 ) ) ) ) ) As you can see [Post], they are not ordered according to [CategoriesPost].postorder but are ordered according to [CategoriesPost].id. How can I get the array ordered according to [CategoriesPost].postorder? Thanks in advance for your time :) Edit: The Queries from Cake's SQL Log are: SELECT `Category`.`id`, `Category`.`name` FROM `categories` AS `Category` WHERE 1 = 1 SELECT `Post`.`id`, `Post`.`title`, `CategoriesPost`.`id`, `CategoriesPost`.`post_id`, `CategoriesPost`.`category_id`, `CategoriesPost`.`postorder` FROM `posts` AS `Post` JOIN `categories_posts` AS `CategoriesPost` ON (`CategoriesPost`.`category_id` IN (13, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52) AND `CategoriesPost`.`post_id` = `Post`.`id`) What I am looking for is how to make cake put a Order By CategoriesPost.postorder in that second SELECT SQL Query.

  • Deleting an element from an array in perl

    - by Flamewires
    Hey I'm wondering how i can get this code to work, basically i want to keep the lines of $filename as long as they contain the $user in the path. Sry, perl noob. open STDERR, ">/dev/null"; $filename=`find -H /home | grep $file`; @filenames = split(/\n/, $filename); for $i (@filenames) { if ($i =~ m/$user/) { #keep results } else { delete $i; # does not work. } } $filename = join ("\n", @filenames); close STDERR; I know you can delete like delete $array[index] but I don't have an index with this kind of loop that I know of.

  • Weird compile-time behavior when trying to use primitive type in generics

    - by polygenelubricants
    import java.lang.reflect.Array; public class PrimitiveArrayGeneric { static <T> T[] genericArrayNewInstance(Class<T> componentType) { return (T[]) Array.newInstance(componentType, 0); } public static void main(String args[]) { int[] intArray; Integer[] integerArray; intArray = (int[]) Array.newInstance(int.class, 0); // Okay! integerArray = genericArrayNewInstance(Integer.class); // Okay! intArray = genericArrayNewInstance(int.class); // Compile time error: // cannot convert from Integer[] to int[] integerArray = genericArrayNewInstance(int.class); // Run time error: // ClassCastException: [I cannot be cast to [Ljava.lang.Object; } } I'm trying to fully understand how generics works in Java. Things get a bit weird for me in the 3rd assignment in the above snippet: the compiler is complaining that Integer[] cannot be converted to int[]. The statement is 100% true, of course, but I'm wondering WHY the compiler is making this complaint. If you comment that line, and follow the compiler's "suggestion" as in the 4th assignment, the compiler is actually satisfied!!! NOW the code compiles just fine! Which is crazy, of course, since like the run time behavior suggests, int[] cannot be converted to Object[] (which is what T[] is type-erased into at run time). So my question is: why is the compiler "suggesting" that I assign to Integer[] instead for the 3rd assignment? How does the compiler reason to arrive to that (erroneous!) conclusion?

  • Fastest PHP Routine To Match Words

    - by Volomike
    What is the fastest way in PHP to take a keyword list and match it to a search result (like an array of titles) for all words? For instance, if my keyword phrase is "great leather shoes", then the following titles would be a match... Get Some Really Great Leather Shoes Leather Shoes Are Great Great Day! Those Are Some Cool Leather Shoes! Shoes, Made of Leather, Can Be Great ...while these would not be a match: Leather Shoes on Sale Today! You'll Love These Leather Shoes Greatly Great Shoes Don't Come Cheap I imagine there's some trick with array functions or a RegEx (Regular Expression) to achieve this rapidly.

  • Retrieving data from a JSON sub array in javascript, where identifier starts with an integer

    - by Archie Ec
    I must be missing something simple here, but I'm having trouble retrieving data from a JSON array response. I can access objects with identifiers that start with letters, but not ones that start with numbers. For example, I can access data.item[0].specs.overview.details But I can't access data.item[0].specs.9a99.details If anyone can point me in the right direction, I'd really appreciate it. Thanks.

  • What happens to a class in PHP once its been instantiated?

    - by Caylem
    Hi I'm just playing around with some PHP and was wondering what happens when an object from a class is created within another PHP script? I assume once its created and been processed their is no way of then going back and 'playing' around with it from another script? The idea is i'm trying to create a kind of deck of cards using a card class, each card has specific data that is added to each individual object to make it unique, suit, value etc. Once its created i need to be able to go back to specific cards to use them. In java i'd have an arraylist of card objects, i'm not sure how to approach the same area in PHP. Thanks.

  • How can i pass a single additional argument to array_map callback in PHP?

    - by Gremo
    How can i pass a single additional argument to array_map callback? In my example i'd like to pass $smsPattern (as a second argument, after current element in $featureNames) to the function array_map with $getLimit closure: $features = $usage->getSubscription()->getUser()->getRoles(); // SMS regular expression in the form of ROLE_SEND_SMS_X $smsPattern = '/^ROLE_SEND_SMS_(?P<l>\d+)$/i'; // Function to get roles names and X from a role name $getNames = function($r) { return trim($r->getRole()); }; $getLimit = function($name, $pattern) { if(preg_match($pattern, $name, $m)) return $m['l']; }; // Get roles names and their limits ignoring null values with array_filter $featuresNames = array_map($getNames, $features); $smsLimits = array_filter(array_map($getLimit, $featureNames, $smsPattern)); With this code i'm getting a weird warning: Warning: array_map() [function.array-map]: Argument #3 should be an array. Of course di reason is for reusing $getLimit closure with another regular expression like $smsPattern. Thanks.

  • Check if key exists in $_SESSION by building index string

    - by Kim
    I need to check if a key exists and return its value if it does. Key can be an array with subkeys or endkey with a value. $_SESSION['mainKey']['testkey'] = 'value'; var_dump(doesKeyExist('testkey')); function doesKeyExist($where) { $parts = explode('/',$where); $str = ''; for($i = 0,$len = count($parts);$i<$len;$i++) { $str .= '[\''. $parts[$i] .'\']'; } $keycheck = '$_SESSION[\'mainKey\']' . $str; if (isset(${$keycheck})) { return ${$keycheck}; } // isset($keycheck) = true, as its non-empty. actual content is not checked // isset(${$keycheck}) = false, but should be true. ${$var} forces a evaluate content // isset($_SESSION['mainKey']['testkey']) = true } What am I doing wrong ? Using PHP 5.3.3.

  • Need help setting up json array

    - by torr
    A database query returns several rows which I loop through as follows: foreach ($query->result() as $row) { $data[$row->post_id]['post_id'] = $row->post_id; $data[$row->post_id]['post_type'] = $row->post_type; $data[$row->post_id]['post_text'] = $row->post_text; } If I json_encode the resulting array ($a['stream']) I get { "stream": { "1029": { "post_id": "1029", "post_type": "1", "post_text": "bla1", }, "1029": { "post_id": "1030", "post_type": "3", "post_text": "bla2", }, "1029": { "post_id": "1031", "post_type": "2", "post_text": "bla3", } } } But the json should actually look like this: { "stream": { "posts": [{ "post_id": "1029", "post_type": "1", "post_text": "bla1", }, { "post_id": "1030", "post_type": "3", "post_text": "bla2", }, { "post_id": "1031", "post_type": "2", "post_text": "bla3", }] } } How should I build my array to get this json right?

  • jQuery Grouping Similar Items and Counting When Repeated

    So I have this structure setup: <ul> <li>http://www.youtube.com/watch?v=dw1Vh9Yzryo</li> (Vid1) <li>http://www.youtube.com/watch?v=bOF3o8B292U</li> (Vid2) <li>http://www.youtube.com/watch?v=yAY4vNJd7A8</li> (Vid3) <li>http://www.youtube.com/watch?v=yAY4vNJd7A8</li> <li>http://www.youtube.com/watch?v=dw1Vh9Yzryo</li> <li>http://www.youtube.com/watch?v=bOF3o8B292U</li> <li>http://www.youtube.com/watch?v=yAY4vNJd7A8</li> <li>http://www.youtube.com/watch?v=dw1Vh9Yzryo</li> </ul> Vid1 is repeated 3 times, Vid2 is repeated 3 times, and Vid3 is repeated 2 times. I want to put them into a structure where I can reference them like this: Vid1 - 3 (Repeated), http://www.youtube.com/get_video?video_id=dw1Vh9Yzryo&fmt=36 (Download) Vid2 - 3 (Repeated), http://www.youtube.com/get_video?video_id=bOF3o8B292U&fmt=36 (Download) Vid3 - 2 (Repeated), http://www.youtube.com/get_video?video_id=yAY4vNJd7A8&fmt=36 (Download) "This video was repeated " + [Vid1][Repeated] + " times and you can download it here: " + [Vid1][Download]; How can I set this structure up? I think I should be using an array to achieve the above but I'm not sure how I would set it up or how to reference certain things in the array. The other question is how can I get how many times something was repeated? The URL I have no problem with. Can anyone help me out?

  • PHP in_array() can't even match a single character. Strict is set to true.

    - by solefald
    I've seen a million of these threads here already, and read through every single one already. Including some serious time Googling. Nothing complicated. All I have to do is check if a single character in a loop matches my alphabet array. print_r($alphabet); // all 26 letters Array ( [0] => a [1] => b [2] => c ... [23] => x [24] => y [25] => z ) print_r($emptyLetters); // dynamic array. Array ( [0] => b [1] => s ) foreach($alphabet as $letter): { echo $letter . '<br />' // Correctly prints out every letter from $alphabet. if(in_array($letter, $emptyLetters, true)): // $strict is set // do something endif; } What the hell is going on??? I do not understand what i am doing wrong.... I tried every combination and option possible, but for some reason even array_search() is bit working...

  • PHP: Use a string as an array index path to retreive a value.

    - by Charles
    Say I have an array like: Array ( [0] => Array ( [Data] => Array ( [id] => 1 [title] => Manager [name] => John Smith ) ) [1] => Array ( [Data] => Array ( [id] => 1 [title] => Clerk [name] => ( [first] => Jane [last] => Smith ) ) ) ) I want to be able to build a function that I can pass a string to that will act as the array index path and return the appropriate array value without using eval(). Is that possible? function($indexPath, $arrayToAccess) { //$indexPath would be something like [0]['Data']['name'] which would return //"Manager" or it could be [1]['Data']['name']['first'] which would return //"Jane" but the amount of array indexs that will be in the index path can //change, so there might be 3 like the first example, or 4 like the second. return $arrayToAccess[$indexPath] <-obviously wont work }

  • Chrome extension javascript array bug?

    - by Wayne Werner
    Hi, I'm working on a Google Chrome extension. In the popup I have the following code: var bookmarks = []; function appendBMTnode(node){ bookmarks.push([node[0].title, node[0].id]); } function addchildren(results){ for(x = 0; x < results.length; x++){ bookmarks.push([results[x].title, results[x].id]); chrome.bookmarks.getChildren(results[x].id, addchildren); } } function getallbookmarks(){ chrome.bookmarks.get('0', appendBMTnode); chrome.bookmarks.getChildren('0', addchildren); } console.debug(bookmarks.length); console.debug(bookmarks); Now, I would assume that the first command would issue the # of bookmarks I have. Indeed, when I use Chrome's debugger and add bookmarks.length to the watch list, 418 is the value. In the console of the debugger I can write bookmarks.length and it will give me the correct length. I can type for(x = 0; x < bookmarks.length; x++){ console.debug(bookmarks[x]); } and I get string representations of each inner array. However, that original console.debug(bookmarks.length) gives an output of zero. And if I add console.debug(bookmarks[0]); to the popup.html it tells me that the value is undefined. This seems like a bug to me, but my real question is how can I iterate over this list? Thanks

  • Ruby: how to know depth of multidemensional array

    - by hqt
    This is my problem I have met in my assignment. Array A has two elements: array B and array C. Array B has two elements: array D and array E At some point, array X just contains two elements: string a and string b. I don't know how to determine how deep array A is. For example: arrA = [ [ [1,2] ] ] I have tested by: A[0][0][0] == nil which returns false. Moreover, A[0][0]..[0] == nil always returns false. So, I cannot do this way to know how deep array A is.

  • Send mail to multiple recipient

    - by Ahmad Maslan
    Hi, i have already research on using the mail() to send to multiple recipient's but i just cant get it to work. What im trying to do is, for every order that i have, order 1,2,3, each having their own email addresses, when i change their order status from pending to confirm, the mail() will use that id to refer to the db table and send the email of those 3 orders. But for my case, it mailed just the latest order which is order 3. This is the form that i use to change the order status. <form action="results-action" method="post" enctype="multipart/form-data"> <fieldset> <table id ="table_id" class="display"> <thead> <tr><td><h2>Pending Order</h2></td></tr> <tr> <th scope="col">Order ID</th> <th scope="col"> </th> <th scope="col">Name</th> <th scope="col">Address</th> <th scope="col">Product Name</th> <th scope="col">Produt Quantity</th> <th scope="col">Price</th> <th scope="col">Order status</th> </tr> </thead> <tbody> <?php while ($row = mysqli_fetch_array($result)) { ?> <tr> <td><input type="text" value='<?=$row['virtuemart_order_id']?>' name="orderid" id="virtuemart_order_id"></td> <td><input type="hidden" value='<?=$row['virtuemart_product_id']?>' name="productid" id="virtuemart_product_id"></td> <td><?=$row['first_name']?></td> <td><?=$row['address_1']?></td> <td><?=$row['order_item_name']?></td> <td><?=$row['product_quantity']?></td> <td><?=$row['product_final_price'] ?></td> <td><select name='change[<?=$row['virtuemart_order_id']?>]'> <option value='C'> Confirmed</option> <option value='X'> Cancelled</option></select></td> </tr> <?php } ?> </tbody> </table> </fieldset> <fieldset> <table> <tr> <td><input type="submit" value="Update status" name="update status"> </td> </tr> </table> </fieldset> </form> This is the php, using the order id from the form to select the email addresses. <?php $orderid = $_POST['orderid']; // build SQL statement to select email addresses $query3 = "SELECT email from ruj3d_virtuemart_order_userinfos where virtuemart_order_id = '$orderid'"; // execute SQL statement $result3 = mysqli_query($link, $query3) or die(mysqli_error($link)); $subject = "Order confirmed by Home and decor"; $message = "Hello!
