  • mySQL php query - news/ friends feed

    - by rpsep2
    I want to show a user the recent uploads from their friends. I have the users friends id's in an array: $friends A user could have, potentially, thousands of friends. I can select the uploads from 1 of a users friends with: $row = $mysqli->query("SELECT * FROM photos WHERE uploader_id = ".$friend." ORDER BY date_uploaded DESC LIMIT ".$page.", 25"); But I need to find all of a users friends uploads. I thought about doing this in a loop iterating over the $friends array, but then I'd be potentially running thousands of mysql queries. How can I do this most efficiently? so to clarify: search a 'photos' table for photos which are uploaded by specific users(friends), held in $friends variable, sort by date_uploaded and limit to x results so I can have pages 1, 2, 3 etc.

  • Check variable if explode-able in PHP

    - by ZaneDeFazio
    Not sure if there is a way to check a variable if it is explode-able or not... I have a database of city names some are one word cities and some are multiple word cities EX: Chicago, Los Angeles I keep getting an error when use "implode" when a city name is one word, so I tried using "count" and using an if statement... not having any luck $citi = explode(' ', $row['city']); $count = count($citi); if ($count > 1) { $city = implode('+', $citi); } else { $city = $citi; }

  • PHP readdir() not returning files in alphabetical order

    - by Buggabill
    I am reading through a directory with some pictures and such using a pretty simple implementation of readdir() like the following: if ($handle = opendir($path)) { while (false !== ($szFilename = readdir($handle))) { if ($szFilename[0] !== '.') { if (is_file($path.$szFilename)) { // do stuff } } } } The problem that I am having is that the files are not being read in alphabetical order as the docs for readdir() state: Returns the filename of the next file from the directory. The filenames are returned in the order in which they are stored by the filesystem. Another weird thing is that, on the local testing server, the same code works great. This is running on a server using the LAMP stack in both cases. I know that I can build an array and just sort it, but I was wondering if I was missing something in what I was doing. Thanks for any insight!

Currently I'm sending the message as a parameter through the URL, however this makes it look quite ugly. Is there a way to pass this value as a post variable instead? Any advice appreciated. Thanks.

When I run the function I end up with two records stacked on top of each one second apart here is the function: function generate_signup_token(){ $connection = new DB_Connect(); // <--- my database connection class $ip = mysql_real_escape_string($_SERVER['REMOTE_ADDR']); $sign_up_token = uniqid(mt_rand(), true); $_SESSION['signup_token'] = $sign_up_token; $sign_up_token = mysql_real_escape_string($sign_up_token); $query = "INSERT INTO `token_manager` (`ip_address`, `signup_token`) VALUES ('$ip', '$sign_up_token')"; mysql_query($query); } generate_signup_token();

  • second sorting with php usort

    - by bluedaniel
    So Ive got a pretty big array of data and need to sort them by two criteria. There is variable $data['important'] and $data['basic']. They are simple numbers and I am using uasort to sort $data firstly by important and then by basic. So Important | Basic 10 | 8 9 | 9 9 | 7 7 | 9 The usort function is a simple public function sort_by_important($a, $b) { if ($a[important] > $b[important]) { return -1; } elseif ($b[important] > $a[important]) { return 1; } else { return 0; } } How can I re-sort the array to the second variable and keep the Important ordering? Thanks everyone. EDIT How about adding a third sorting option after this even? So Important Basic Less

    - by Ramesh
    i have an paragraph and user will search inside that and if the search term has 3 matches inside but all are in 3 different places ex World War II, or the Second World War[1] (often abbreviated WWII or WW2), was a global military conflict lasting from 1939 to 1945 which involved most of the world's nations, including all of the great powers, organised into two opposing military alliances: the Allies and the Axis. It was the most widespread war in history, with more than 100 million military personnel mobilised. In a state of "total war," the major participants placed their entire economic, industrial, and scientific capabilities at the service of the war effort, erasing the distinction between civilian and military resources. Marked by significant action against civilians, including the Holocaust and the only use of nuclear weapons in warfare, it was the deadliest conflict in human history,[2] with over seventy million casualties. i have to search "war" so that it should display like World War II, or the Second World War[1].....In a state of "totalwar,".... some thing like this ///

  • How to add a suffix at the end of a string in PHP

    - by Golem
    I am trying to add a .html suffix at the end of all strings supplied by the user before it is entered into the database. Here's my code so far: strtolower(str_replace(" ", "_", $postTitle)); The above takes the title of the post the user it trying to make, turns it to lower case, replaces all white spaces with underscores and makes it ready to be entered into a database column called post_url. I just need it to do one more thing and that's to add a .html at the end of each post url. What is the function to do this?
