I prefer to use SVN it is fast, easy to use and its support is build in in NetBeans IDE. Since I use hosting at 1and1 I tried to install my own SVN repository there. It is very easy and it worked almost instantly.

First step: create svn repository on the server.

Just SSH to your account and create a new directory and svn repository in it:

cd /
mkdir svn
svnadmin create /kunden/homepages/……/htdocs/svn

to get a full path to your home directory call “pwd” command and replace ……. with your information

Now your svn repository is set up – we can procees to the second step: netbeans configuration

from putty download page (here) get plink.exe and place it in c:\Program Files\Putty\ (you can choose different path)
now in your Project window right click on your project name and select Versioning->Import into subversion repository
for Repository URL select svn+ssh:// and enter:svn+ssh://your.domain.com/kunden/homepages/……./htdocs/svn (same path that you have used for svnadmin command)
then as Tunnel Command enter: C:/Program Files/Putty/plink.exe -l ssh_username -pw ssh_password
click Next
now in “Repository Folder” enter desired name like “my_project”
enter a message – for example “initial import”
click Next again
after a while you will be prompted what files you want to import – usually you want to import whole project so just click Finish

And you are done – enjoy your SVN on 1and1 account

the only thing that I don’t like is having open text password for my ssh account in netbeans – it I find a way to hide somewhere I will share it with you

You can find plenty of similar functions but this one is a little bit different. As a parameter you specify new MAX dimensions so image will be scaled based on its height or width. I believe I have enough comments in the code.

public function resize($source_image, $target_image, $new_width, $new_height) {
  // get current size
  list($width, $height) = @getimagesize($source_image);
 
  if ($width > $new_width || $height > $new_height) {
    $scale1 = $width / $new_width;
    $scale2 = $height / $new_height;
 
    // check if we should scale using width or height
    $scale = $scale1 > $scale2 ? $scale1 : $scale2;
 
    // make sure we scale correctly
    $new_height = floor($height / $scale);
    $new_width = floor($width / $scale);
 
    // Load
    $thumb = imagecreatetruecolor($new_width, $new_height);
    $source = imagecreatefromjpeg($source_image);
 
    // Resize
    imagecopyresampled($thumb, $source, 0, 0, 0, 0, $new_width, $new_height, $width, $height);
 
    // Save the file at 95% quality
    imagejpeg($thumb, $target_image, 95);
  } else {
    // image small already - don't resize
    copy($source_image, $target_image);
  }
}

If you ask me six months ago I would say “I heard about it but I don’t see any benefit in using it. I know javascript well enough to write my own code”.

And I was sooooo WRONG.

I just finished small project for my friend www.jardinsdesreves.pl and I decided to give it a try.
The benefit: my js file is only 170 lines long.

I just want to show you couple benefits of this wonderfull framework.

FORMS:

I have never seen a simpler way to submit forms via ajax.

Just look at the simple example:

<form>
  <input type="hidden" name="id" value="2">
  <input type="hidden" name="save" value="1">
  Title: <input type="text" name="form_title"><br>
  Content: <textarea name="form_content" cols="25" rows="8"></textarea>
  <input type="button" value="Save changes" onclick="sendForm('text_save.php');">
</form>

function sendForm(post_url) {
  var request = $("form").serialize();
  $.post(post_url, request, function(data) {
    formResponse(data);
  });
}
 
function formResponse(resp_data) {
  $("#message").text(resp_data);
}

As you can see jQuery does all job for us.
There is only one requirement – each form element needs to have a name (not id).

serialize() function does great job and will post all form to ‘text_save.php’ where we can do processing and show response to the user.

In the next article I will show you how to use great jQuery plugin ‘ajaxfileupload.js’ to upload files.

I hope to find enough time to write some articles about web development (PHP, Javascript, CSS, Flex …) and my hobby photography.

I spend a lot of time writing code and even more time googling around for help and solutions. I know how difficult it is to find something useful. That’s why on my blog I will post only useful information and I will try not to copy anything that is already posted on other blogs.

Don’t expect to find a new post every day but if you have any questions or comments to my articles I will respond ASAP

Lets get started
