  • Image upload not functioning correctly

    - by PurpleSmurf
    I'm still trying to get to grips with PHP, and I'm trying to make a form that uploads a picture to a database. I don't have permissions for move_uploaded_file so I'm using the copy() as an alternative. Everywhere I've seen experiencing similar problems have all been with move_uploaded_file so I'm rather stuck. Trying to copy the image from the desktop doesn't seem to be working, it's not throwing up any more PHP errors but is displaying the error message for if something goes wrong. The form sends data to two tables in the database but I'm mainly concerned with the upload not working. There's over 200 lines so I'll post a snippet of the upload code, thank you in advance: function getExtension($str) { $i = strrpos($str,"."); if (!$i) { return ""; } $l = strlen($str) - $i; $ext = substr($str,$i+1,$l); return $ext; } //This variable is used as a flag. The value is initialized with 0 (meaning no error found) and it will be changed to 1 if an errro occures. If the error occures the file will not be uploaded. $errors=0; //checks if the form has been submitted if(isset($_POST['submitted'])) { //reads the name of the file the user submitted for uploading $image=$_FILES['image']['name']; //if it is not empty if ($image) { //get the original name of the file from the clients machine $filename = stripslashes($_FILES['image']['name']); //get the extension of the file in a lower case format $extension = getExtension($filename); $extension = strtolower($extension); //if it is unknown extension, class as an error and do not upload the file, otherwise continue if (($extension != "jpg") && ($extension != "jpeg") && ($extension != "png") && ($extension != "gif")) { //print error message echo '<h1>Unknown extension!</h1>'; $errors=1; } else { //get the size of the image in bytes //$_FILES['image']['tmp_name'] is the temporary filename of the file in which the uploaded file was stored on the server $size=filesize($_FILES['image']['tmp_name']); //give an unique name, for example the time in unix time format $image_name=time().'.'.$extension; //the new name will be containing the full path where will be stored (images folder) $newname="/home/k0929907/www/uploads/".$image_name; //verify if the image has been uploaded, and print error instead $copied = copy($_FILES['image']['tmp_name'], $newname); if (!$copied) { echo '<h1>Copy unsuccessfull!</h1>'; $errors=1; } } } }

  • A good Java library for network math

    - by perilandmishap
    I'm looking for a Java library that is geared towards network math and already tested. Nothing particularly fancy, just something to hold ips and subnets, and do things like print a subnet mask or calculate whether an IP is within a given subnet. Should I roll my own, or is there already a robust library for this?

  • Multithreaded ActiveRecord requests in rspec

    - by jeem
    I'm trying to recreate a race condition in a test, so I can try out some solutions. I find that in the threads I create in my test, ActiveRecord always returns 0 for counts and nil for finds. For example, with 3 rows in the table "foos": it "whatever" do puts Foo.count 5.times do Thread.new do puts Foo.count end end end will print 3 0 0 0 0 0 test.log shows the expected query, the expected 6 times: SELECT count(*) AS count_all FROM `active_agents` Any idea what's going on here?

  • See socket options on existing sockets created by other apps?

    - by nailer
    I'd like to test whether particular socket options have been set on an existing socket. Ie, pretty much everything you can see in: #!/usr/bin/env python '''See possible TCP socket options''' import socket sockettypelist = [x for x in dir(socket) if x.startswith('SO_')] sockettypelist.sort() for sockettype in sockettypelist: print sockettype Anyone know how I can see the options on existing sockets, ie those created by other processes? Alas nearly all the documentation I read on Python socket programming is about making new sockets.

  • How can I compare two jpeg encoding and other inormations

    - by Subhen
    We have created a Driver programe which connect to a remote host using FTP and mount the remote host as a network drive. So when I try to copy some data it copies using FTP retrieve request and then paste it to the destination. The copy paste works fine as we can see the source file size and destination size are same. But while we try to open the .jpg file that is being copied , says no preview. I suspect there must be some bytes that is being corrupted while we try to copy and paste. Is there any tools so that I can compare both source and destination to get the differences.

  • Perl, "closure" using Hash

    - by Mike
    I would like to have a subroutine as a member of a hash which is able to have access to other hash members. For example sub setup { %a = ( txt => "hello world", print_hello => sub { print ${txt}; }) return %a } my %obj = setup(); $obj{print_hello}; Ideally this would output "hello world"

  • What should I learn & use to become a pro in PHP & Python Web development?

    - by pecker
    Hello, I'll just show some code to show how I do web development in PHP. <html> <head> <title>Example #3 TDavid's Very First PHP Script ever!</title> </head> <? print(Date("m/j/y")); require_once("somefile.php"); $mysql_db = "DATABASE NAME"; $mysql_user = "YOUR MYSQL USERNAME"; $mysql_pass = "YOUR MYSQL PASSWORD"; $mysql_link = mysql_connect("localhost", $mysql_user, $mysql_pass); mysql_select_db($mysql_db, $mysql_link); $result = mysql_query("SELECT impressions from tds_counter where COUNT_ID='$cid'", $mysql_link); if(mysql_num_rows($result)) { mysql_query("UPDATE tds_counter set impressions=impressions+1 where COUNT_ID='$cid'", $mysql_link); $row = mysql_fetch_row($result); if(!$inv) { print("$row[0]"); } } ?> <body> </body> </html> Thats it. I write every file like this. Recently, I learnt OOP and started using classes & objects in PHP. I hear that there are many frameworks there for PHP. They say that one must use these libraries. But I feel they are just making things complicated. Anyway, this is how I've been doing my web development. Now, I want to improve this. and make it professional. Also I want to move to Python. I searched SO archives and found everyone suggesting Django. But, can any one give me some idea about how web development in Python works? user (client) request for page --- webserver(-embedded PHP interpreter) ---- Server side(PHP) Script --- MySQL Server. Now, is it that instead of PHP interpreter there is python interpreter & instead of php script there is python script, which contains both HTML & python (embedded in some kind of python tags). Python script connects to database server and fetches some data which will be printed as HTML. or is it different in python world? Is this Django thing like frameworks for PHP? Can't one code in python without using Django. Because, I never encountered any post without django Please give me some kick start.

  • _REQUIREDNAME always nil

    - by Nali4Freedom
    I'm trying to use the method for naming a lua package after the filename mentioned here, however _REQUIREDNAME is never defined. For example I have these two files samplePackage.lua: print("_REQUIREDNAME: ", _REQUIREDNAME) return nil; packageTest.lua: require "samplePackage" And when I run packageTest.lua it outputs > _REQUIREDNAME: nil I also couldn't find any mention of _REQUIREDNAME in the Lua 5.1 Refrence manual, so was this removed from the language, or am I missing something?

  • Python 3.2: How to pass a dictionary into str.format()

    - by Robert Dailey
    I've been reading the Python 3.2 docs about string formatting but it hasn't really helped me with this particular problem. Here is what I'm trying to do: stats = { 'copied': 5, 'skipped': 14 } print( 'Copied: {copied}, Skipped: {skipped}'.format( stats ) ) The above code will not work because the format() call is not reading the dictionary values and using those in place of my format placeholders. How can I modify my code to work with my dictionary?
