  • Why PHP Error: Call to a member function set_prefix() on a non-object

    - by Rebol Tutorial
    I got this error Fatal error: Call to a member function set_prefix() on a non-object in /home/reboltutorial/reboltutorial.com/wp-settings.php on line 254 line 254 contains: $prefix = $wpdb->set_prefix($table_prefix); // set up global tables This occurs if I try to call index_wordpress() instead of calling these two lines define('WP_USE_THEMES', true); require('./wp-blog-header.php'); so this doesn't work: <?php function index_wordpress() { define('WP_USE_THEMES', true); require('./wp-blog-header.php'); } ?> <?php if(!function_exists('apache_request_headers')) { function apache_request_headers() { $headers = array(); foreach($_SERVER as $key => $value) { if(substr($key, 0, 5) == 'HTTP_') { $headers[str_replace(' ', '-', ucwords(str_replace('_', ' ', strtolower(substr($key, 5)))))] = $value; } } return $headers; } } function getCurrentPageUrl() { $pageURL = 'http'; if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";} $pageURL .= "://"; if ($_SERVER["SERVER_PORT"] != "80") { $pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"]; } else { $pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"]; } return $pageURL; } $a = apache_request_headers(); $pos = strrpos($a["User-Agent"], "REBOL"); if ($pos === false) { index_wordpress(); } else { if ($_SERVER['REMOTE_ADDR'] != "69.163.203.14") { $command= './cgi-bin/index.cgi '. '"' . getCurrentPageUrl() . '"'; echo system($command); } else { index_wordpress(); } } ?> while this works: <?php if(!function_exists('apache_request_headers')) { function apache_request_headers() { $headers = array(); foreach($_SERVER as $key => $value) { if(substr($key, 0, 5) == 'HTTP_') { $headers[str_replace(' ', '-', ucwords(str_replace('_', ' ', strtolower(substr($key, 5)))))] = $value; } } return $headers; } } function getCurrentPageUrl() { $pageURL = 'http'; if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";} $pageURL .= "://"; if ($_SERVER["SERVER_PORT"] != "80") { $pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"]; } else { $pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"]; } return $pageURL; } $a = apache_request_headers(); $pos = strrpos($a["User-Agent"], "REBOL"); if ($pos === false) { define('WP_USE_THEMES', true); require('./wp-blog-header.php'); } else { if ($_SERVER['REMOTE_ADDR'] != "69.163.203.14") { $command= './cgi-bin/index.cgi '.

  • Binding a collection to Listbox

    - by Blub
    Hi, I basically started today with WPF, and I'm astounded by how difficult it is to do binding. I have an array of Textboxes, in an ObservableCollection, and just want to bind that in my Listbox, so that they arrange themselves vertically. I have fiddled around with this for 3 already, can you help? I'm working in a Wpf "UserControl", not a window as so many tutorials seem to rely on.

  • Can PHP and Oracle pass complex types to each other?

    - by RenderIn
    I want to pass/bind an array of (key1, key2) to an Oracle PL/SQL stored procedure using PHP. I'm able to bind primitive types and arrays of primitive types, but haven't found a way to pass complex datatypes back and forth. Is this unsupported? So far I've been having to pass along multiple arrays -- one for each subtype in my complex type -- and then depend on their indexes to reconstitute them in the procedure.

  • C++ - 3 possible values in Variable?

    - by noryb009
    I need to store a 30 letter combination, but each letter can only be "0", "1" or "2". When I use sizeof(myString), it returns 32. I want to use this 30 letter combination to access a row of an array, so I'm wondering if it is possible to use a 3 value bool of some sort to store 1 of 3 values in.

  • Form filter in symfony: imposible when a field is type "date"

    - by user248959
    Hi, anyone has tried to create a symfony form filter from a class which has a field of type "date" ? When i do it, i get this error: 500 | Internal Server Error | Doctrine_Connection_Mysql_Exception SQLSTATE[HY093]: Invalid parameter number: number of bound variables does not match number of tokens stack trace I think the error dependens on this command: 'SELECT b.id AS b_id, b.day AS b_day FROM birthday b WHERE b.day = ? AND b.day <= ?', array('month' = '1','day' = '2', 'year' = '2014') but i dont know how can i solve it.. Any idea? Javi

  • Bulk update & occasional insert (coredata) - Too slow

    - by Andrew
    Update: Currently looking into NSSET's minusSet links: http://stackoverflow.com/questions/1475636/comparing-two-arrays Hi guys, Could benefit from your wisdom here.. I'm using Coredata in my app, on first launch I download a data file and insert over 500 objects (each with 60 attributes) - fast, no problem. Each subsequent launch I download an updated version of the file, from which I need to update all existing objects' attributes (except maybe 5 attributes) and create new ones for items which have been added to the downloaded file. So, first launch I get 500 objects.. say a week later my file now contains 507 items.. I create two arrays, one for existing and one for downloaded. NSArray *peopleArrayDownloaded = [CoreDataHelper getObjectsFromContext:@"person" :@"person_id" :YES :managedObjectContextPeopleTemp]; NSArray *peopleArrayExisting = [CoreDataHelper getObjectsFromContext:@"person" :@"person_id" :YES :managedObjectContextPeople]; If the count of each array is equal then I just do this: NSUInteger index = 0; if ([peopleArrayExisting count] == [peopleArrayDownloaded count]) { NSLog(@"Number of people downloaded is same as the number of people existing"); for (person *existingPerson in peopleArrayExisting) { person *tempPerson = [peopleArrayDownloaded objectAtIndex:index]; // NSLog(@"Updating id: %@ with id: %@",existingPerson.person_id,tempPerson.person_id); // I have 60 attributes which I to update on each object, is there a quicker way other than overwriting existing? index++; } } else { NSLog(@"Number of people downloaded is different to number of players existing"); So now comes the slow part. I end up using this (which is tooooo slow): NSLog(@"Need people added to the league"); for (person *tempPerson in peopeArrayDownloaded) { NSPredicate *predicate = [NSPredicate predicateWithFormat:@"person_id = %@",tempPerson.person_id]; // NSLog(@"Searching for existing person, person_id: %@",existingPerson.person_id); NSArray *filteredArray = [peopleArrayExisting filteredArrayUsingPredicate:predicate]; if ([filteredArray count] == 0) { NSLog(@"Couldn't find an existing person in the downloaded file. Adding.."); person *newPerson = [NSEntityDescription insertNewObjectForEntityForName:@"person" inManagedObjectContext:managedObjectContextPeople]; Is there a way to generate a new array of index items referring to the additional items in my downloaded file? Incidentally, on my tableViews I'm using NSFetchedResultsController so updating attributes will call [cell setNeedsDisplay]; .. about 60 times per cell, not a good thing and it can crash the app. Thanks for reading :)

  • wav file manupalation

    - by kaushik
    I want get the details of the wave such as its frames into a array of integers. Using fname.getframes we can ge the properties of the frame and save in list or anything for writing into another wav or anything,but fname.getframes gives information not in integers some thing like a "/xt/x4/0w' etc.. But i want them in integer so that would be helpful for manupation and smoothening join of 2 wav files
