Before : http://www.example.com/?a=3&id=5&start=0 After : http://www.example.com/?a=3 Before : http://www.example.com/?id=5&start=0 After : http://www.example.com/ Before : http://www.example.com/?alpha=1&id=5&start=0&beta=2 After : http://www.example.com/?alpha=1&beta=2Thank you Edited by Dareros, 11 August 2014 - 04:06 PM. I know this one is probably super easy for you programmer types.. but I just need to know.. If a string ends with a dash (and not all of them will), how do I remove it? Thanks! I have sen this function before but can not remember what it is or how to code it. It allows you remove only defined characters from the end of the string. I am not looking to replace any occurrence anywhere in the phrase, just the end. For example lets say I want to remove"ld!" from phrase "Hello World!" That function would return "Hello Wor" Thanks I have a form with some dropdownlist that get populated dynamically(depends on what the user chooses) with jquery and an xml file. In the form I have a button that takes the info and populates another form with the values of the ddl. I have coded script which populates the second form with jquery and the name of each input get dynamically added like so: Code: [Select] <input type="text" value="'+model+'" name="Model_'+model+'" id="'+model+'" readonly size="'+model.length+'" /> <input type="text" value="'+model+'" name="Model'+model+'" id="'+model+'" readonly size="'+model.length+'" />> <input type="text" value="'+color+'" name="Color'+color+'" id="'+color+'" readonly size="'+color.length+'" /> <input type="text" value="'+part+'" name="Part'+part+'" id="'+part+'" readonly size="'+part.length+'" /> <input type="text" value="$'+price+'" name="Price'+price+'" id="'+price+'" readonly size="'+price.length+'" /> <input type="text" value="'+qty+'" name="Quantity'+qty+'" id="'+qty+'" readonly size="'+qty.length+'" /> <input type="text" value="'+total+'" name="Total'+total+'" id="'+total+'" readonly size="'+total.length+'" /> What I want to do is grab the name of the element and remove the underscore and everything else form rileft to right so I am left with just the word before the underscore. I tried using substr($key,0,-28) but that wont work since everything after the underscore will have a different length. I was wondering if there is a way i can keep everything before the underscore and remove the underscore and everything after that. Thanks in advance for any input I get. I have some data in a table and some of it is Artist names stored as "Last, First" I need to be able to have the script search weather or not someone types "last, first" or "first last". Any ideas? Here's my code: <html> <head> <title>search script</title> </head> <body> <form name="form" action="search.php" method="get"> <input type="text" name="q" /> <input type="submit" name="Submit" value="Search" /> </form> <?php // Get the search variable from URL $var = @$_GET['q'] ; $trimmed = trim($var); //trim whitespace from the stored variable // rows to return $limit=100; // check for an empty string and display a message. if ($trimmed == "") { echo "<p>Please enter a search...</p>"; exit; } // check for a search parameter if (!isset($var)) { echo "<p>We dont seem to have a search parameter!</p>"; exit; } //connect to your database ** EDIT REQUIRED HERE ** mysql_connect("localhost","username","password"); //(host, username, password) //specify database mysql_select_db("mydb") or die("Unable to select database"); //select which database we're using // Build SQL Query $query = "select * from songs where Title like \"%$trimmed%\" or Artist like \"%$trimmed%\" order by Title"; // EDIT HERE and specify your table and field names for the SQL query $numresults=mysql_query($query); $numrows=mysql_num_rows($numresults); // If we have no results, offer a google search as an alternative if ($numrows == 0) { echo "<h4>Results</h4>"; echo "<p>Sorry, your search: "" . $trimmed .

Ie, my string is the following: These are my favorite foods: <ul> <li id="1"> Pizza </li> <li id="2"> Burgers </li> <li id="three"> Hot Dogs </li> </ul> I need to get the ID of each list item, i know they will always follow "<li id=". I also need to get the text of each list item, i know they will always be before "</li>" Thanks! hey guys, i have my code set up to run substrings through a db to check for matches...even when there is a match it wont insert correctly Code: [Select] $result = mysql_query("select * from friends where userid=$userid"); while($row = mysql_fetch_assoc($result)) { $first_name = $row['first_name']; $last_name = $row['last_name']; $strpos_1 = strpos($friend_1, ' '); $substr_1 = substr($friend_1, 0, $strpos_1); $substr_2 = substr($friend_1, $strpos_1); if($substr_1 == $first_name && $substr_2 == $last_name) { $sql = "insert into fav_friends values('', '$userid', '$friend_1', '$friend_2', '$friend_3', '$friend_4', '$friend_5', '$friend_6')"; $query = mysql_query($sql); } } and i don't receive any errors, any thoughts? Hey guys. So I'm trying to write a script that replaces footnote citations in one format with footnote citations in another format. For example, the text will read: "Then he went down the street.[1] That is where the police found him [2]. They immediately arrested him at the house. [3]" And I would like the script to find the [ #] strings and replace them with {#} ... so that the string reads: "Then he went down the street.{1} That is where the police found him {2}. They immediately arrested him at the house. {3}" Note that there will be double, and even tripple, digit footnotes, so the script has to be able to recognize [##] or [###] and replace the brackets with {} accordingly. I'm not really sure how to do this, since the "pattern" is constantly changing depending on the number between the brackets. Ideas? Thanks! First problem fixed. My second problem is if the result is 0X.XX,0 or 0X.XX,1 I would like to remove the first 0 The X.XX are numbers, but the 0 is not always there. Can anyone help please Thanks Hi, I am trying to make some adjustments to uploadify.php which comes with the latest version of uploadify (3.0 beta), so that it works with a session variable that stores the login username and adds it to the path for uploads. Here is uploadify.php as it currently looks: Code: [Select] <?php session_name("MyLogin"); session_start(); $targetFolder = '/songs/' . $_SESSION['name']; // Relative to the root if (!empty($_FILES)) { $tempFile = $_FILES['Filedata']['tmp_name']; $targetPath = $_SERVER['DOCUMENT_ROOT'] . $targetFolder; $targetFile = rtrim($targetPath,'/') .'/'. $_FILES['Filedata']['name']; // Validate the file type $fileTypes = array('m4a','mp3','flac','ogg'); // File extensions $fileParts = pathinfo($_FILES['Filedata']['name']); if (in_array($fileParts['extension'],$fileTypes)) { move_uploaded_file($tempFile,$targetFile); echo '1'; } else { echo 'Invalid file type.'; } } echo $targetFolder; ?> I added Code: [Select] echo $targetFolder; at the bottom so that I could make sure that the string returned was correct, and it is, i.e. '/songs/nick'. For some reason though, uploads are not going to the correct folder, i.e. the username folder, but instead are going to the parent folder 'songs'. The folder for username exists, with correct permissions, and when I manually enter Code: [Select] $targetFolder = '/songs/nick';all works fine. Which strikes me as rather strange. I have limited experience of using php, but wonder how if the correct string is returned by the session variable, the upload works differently than with the manually entered string. Any help would be much appreciated. It's the last issue with a website that was due to go live 2 days ago! Thanks, Nick Hey there, Thanks for taking the time to read my thread. My issue is that I can't think of a way to edit a XML file using PHP's XML functionality and then assign the edited contents to a string instead of saving the file. Because my issue is that I have to edit the XML file based upon a string brought from a remote location then give it back to that remote location using a string again, to be exact I am doing it via Linux command line utilizing SSH2. This is what I managed to complete on my own. function CheckIVMPConfig($ServerID) { global $Panel; if(is_numeric($ServerID) && $this->IsValidServer($ServerID)) { // We select the game server that the FTP account was created for. $Servers = mysql_query("SELECT * FROM control_servers WHERE server_id = '".mysql_real_escape_string($FTPAccount['ftp_server'])."'"); $Server = mysql_fetch_array($Servers); // Here we select the Box ID that the game server is on. $Boxs = mysql_query("SELECT * FROM control_machines WHERE machine_id = '".$Server['server_machine']."'"); $Box = mysql_fetch_array($Boxs); // Now we select the required package for the box. $Packages = mysql_query("SELECT * FROM control_packages WHERE package_id = '".$Server['server_package']."'"); $Package = mysql_fetch_array($Packages); // Retrive the file. $Config = $CProtocol->exec("cat /home/{$Server['server_id']}/{$Package['package_config']}"); $Parse = SimpleXMLElement($Config); foreach($Parse as $Entry) // loop through our books { if($Entry->port != $Server['server_port']) { // edit the value } else if($Entry->maxplayers > $Server['server_slots']) { // edit the value } } } } This topic has been moved to PHP Regex. http://www.phpfreaks.com/forums/index.php?topic=326004.0 |
