  • MySQL One to Many order by number found in joined table

    - by Finbarr
    Two tables: table_a ------- table_a_id: (primary, int) table_b ------- table_a_id: (index, int, from table_a) table_b_value: (varchar) A one to many relationship between table_a_id and table_b_value. Given a query like this: SELECT DISTINCT(table_a_id) FROM table_a JOIN table_b ON table_a.table_a_id=table_b.table_a_id I want to order by the number of occurrences of table_a_id in table_b. I'm not really sure how to write this in MySQL.

  • Duplicate array but maintain pointer links

    - by St. John Johnson
    Suppose I have an array of nodes (objects). I need to create a duplicate of this array that I can modify without affecting the source array. But changing the nodes will affect the source nodes. Basically maintaining pointers to the objects instead of duplicating their values. // node(x, y) $array[0] = new node(15, 10); $array[1] = new node(30, -10); $array[2] = new node(-2, 49); // Some sort of copy system $array2 = $array; // Just to show modification to the array doesn't affect the source array array_pop($array2); if (count($array) == count($array2)) echo "Fail"; // Changing the node value should affect the source array $array2[0]->x = 30; if ($array2[0]->x == $array[0]->x) echo "Goal"; What would be the best way to do this?

  • For securing forms, when do I issue the token?

    - by AQuestionADayKeepsTheDrAway
    So, I have a form, to make it a little more secure and potentially help prevent CSRF attacks I want to add a random token value in a hidden field that value is also stored server side in my session data. When should I issue a new token? Per form? Per page load where there is any form? Per session? I can render it invalid as soon as a form is successfully submitted but I'm wondering when to generate one. I ask as if I issue it per form or per page do I not risk the chance of a duplicate token value overwriting the existing (valid) token if a user opens a separate window but submitting the first form (with the now overwritten value)?

  • can I put the break on the same line

    - by brett
    I have a switch statement that has over 300 case statements. case 'hello': { $say = 'some text'; } break; case 'hi': { $say = 'some text'; } break; Why is it that the break is always on a separate line? Is this required? Is there anything syntactically incorrect about me doing this: case 'hello': { $say = 'some text'; } break; case 'hi': { $say = 'some text'; } break;

  • Wordpress Hooks vs. includes?

    - by Chris J. Lee
    This is somewhat a subjective question. Noticed themes like thematic and carrington use hooks to display their themes. Trying to figure out which works best for a more efficient workflow. Which seems more efficient at theming? Trying to weigh in the cons and pros of hooks vs. just including static files.

  • Best way to save info in hash

    - by qwertymk
    I have a webpage that the user inputs data into a textarea and then process and display it with some javascript. For example if the user types: _Hello_ *World* it would do something like: <underline>Hello</underline> <b>World</b> Or something like that, the details aren't important. Now the user can "save" the page to make it something like site.com/page#_Hello_%20*World* and share that link with others. My question is: Is this the best way to do this? Is there a limit on a url that I should be worried about? Should I do something like what jsfiddle does? I would prefer not to as the site would work offline if the full text would be in the hash, and as the nature of the site is to be used offline, the user would have to first cache the jsfiddle-like hash before they could use it. What's the best way to do this?

  • How to remove background of a image and copy into another?

    - by Gustavo Pinent
    I'm researching about captchas. In this idea, the task is: create a image from a JPEG and remove the white background, than create another image from another JPEG, than create the final image by adding the second as a background, and copying the first one over this background preserving the transparent area created, of course. Here is the code: header("Content-Type: image/jpeg"); $nFundo = rand(0,4); $Dirs = array(rand(0,7), rand(0,7), rand(0,7), rand(0,7)); // Will be four times all $_SESSION["form_captcha"] = $Dirs; $image = ImageCreatetruecolor(320, 80); ImageAlphaBlending($image, FALSE); ImageSaveAlpha($image, TRUE); $image_seta = ImageCreateFromJPEG("_captcha-seta.jpg"); // Image do copy over $image_fundo = ImageCreateFromJPEG("_captcha-fundo-".$nFundo.".jpg"); // Image to make the background for($i=0; $i<4; $i++){ ImageCopy($image, $image_fundo, $i*80, 0, 0, 0, 80, 80); } // So far so good, a background with a pattern repeated four times $color_white = ImageColorAllocate($image_seta, 255, 255, 255); ImageColorTransparent($image_seta, $color_white); ImageSaveAlpha($image_seta, TRUE); for($i=0; $i<4; $i++){ $image_seta_rot = imageRotate($image_seta, $Dirs[$i]*45, $color_white); ImageCopyResampled($image, $image_seta_rot, $i*80, 0, 0, 0, 80, 80, 80, 80); // Try } echo(imagejpeg($image)); imagedestroy($image); I tried to replace $image_seta_rot by $image_seta ("Try" line) to see if the rotation is the problem, but even without rotation, the white wasn't removed and the image just "erase" the background created before. So the copy is failing or the white were never removed... I may create a PNG with transparent background, but will be interesting to learn how to make it dynamically, don't you think? Any ideas?

  • WP_Insert_Post and GUID Issue [Wordpress]

    - by morningglory
    Hello, I have a posting form at my theme. I used wp_insert_post there. My code looks like this $post = array( 'ID' => '', 'post_author' => $post_author, 'post_category' => $post_category, 'post_content' => $post_content, 'post_title' => $post_title, 'post_status' => 'publish', ); $post_id = wp_insert_post($post); $fullpost = get_post($post_id); wp_redirect($fullpost->guid); Everything works fine. But when it's inserted to the database, at the GUID field, the entry format is like this permalinks_structure/id. So if my permalinks_structure is like /category/id , it become like http://www.example.com/uncategorized/1. So the problem is, if i post through wordpress admin panel, GUID of the post is http://www.example.com?p=1 . So my post database GUID become mess, because if i want to change permalinks_structure , the post which becomes from outside form will follow the structure. What I want to do is, I want to get the GUID like that I posted through admin panel which is http://www.example.com?p=1 How can i do it ? Please point me out. Thank you.

  • preg_replace replacing with array

    - by Scott
    What I want to do is replace the "[replace]" in input string with the corresponding vaule in the replace array. The total number of values will change but there will always be the same number in the replace array as in input string. I have tried doing this with preg_replace and preg_replace_callback but I can't get the pattern right for [replace], I also tried using vsprintf but the % in <table width="100%"> was messing it up. All help is greatly appreciated! Replace Array: $array = array('value 1','value 2','value 3'); Input String $string = ' <table width="100%"> <tr> <td>Name:</td> <td>[replace]</td> </tr> <tr> <td>Date:</td> <td>[replace]</td> </tr> <tr> <td>Info:</td> <td>[replace]</td> </tr> </table> '; Desired Result <table width="100%"> <tr> <td>Name:</td> <td>value 1</td> </tr> <tr> <td>Date:</td> <td>value 2</td> </tr> <tr> <td>Info:</td> <td>value 3</td> </tr> </table>

  • Should I change $_REQUEST to $_POST

    - by Scarface
    Hey guys quick question, I have a checkbox system where a list of items can be checked and deleted on the click of a button. I currently use request and it does the job but I was wondering if $_REQUEST was some sort of security risk or improper. If anyone has any advice I would appreciate it. Should I change to $_POST? If so, what is the best way to go about it? foreach ($_REQUEST as $key=>$value) { if (substr($key,0,3)==="img") { $id = substr($key,3); if(isset($_REQUEST['Delete'])) { $sql = 'SELECT file_name,username FROM images WHERE id=?'; $stmt = $conn->prepare($sql); $result=$stmt->execute(array($id)); while ($row = $stmt->fetch(PDO::FETCH_ASSOC)) { $image=$row['file_name']; $user=$row['username']; $myFile = "$user/images/$image"; unlink($myFile); } <input id=\"img".$id."\" name=\"img".$id."\" type=\"checkbox\">

  • Hide 'Would you like to remember password' iFrame

    - by nsilva
    Basically I have a website called http://yellow-taxis.uk/ which features an online booking system that is placed on the web site within an iFrame. On the online booking, it automatically logs the user in as a 'Guest' for credit card payments. When the site loads it comes up with a window asking the viewer if they 'would like to remember the password'. I was wondering if there was anyway possible to not display this window as it would be a much simpler option than changing a lot of the code within the online booking. Just to add, the iFrame is hosted on the same server as the web site (not sure if this makes a difference) Any help would be much appreciated.
