Also, replace $this->validation with $this->form_validation in the rest of your code.

In other words, you’re mixing old and new versions of the validation libraries

my code is :
$this->load->library(‘form_validation’);

and…

public function insert_student()
{
$this->load->helper(array(‘form’, ‘url’));
$this->load->library(‘validation’);
$this->load->helper(array(‘form’));
$this->form_validation->set_rules(‘sname’, ‘username’, ‘required’);
$this->form_validation->set_rules(‘email’, ‘Email’, ‘required’);
$this->form_validation->set_rules(‘password’, ‘password’, ‘required’);
$rules['vpassword'] = “required”;
$rules['address'] = “required”;
$rules['gender'] = “required”;
$rules['hobbies'] = “required”;
$rules['class'] = “required”;

$this->validation->set_rules($rules);
if ($this->validation->run() == FALSE)
{
$this->load->view(‘form_view’);
}
else
{
$this->load->model(‘student_insert_model’);
$this->student_insert_model->add_student();
$this->load->helper(‘url’);
redirect(“/index”);

}

Deny from all

Otherwise, submits inside Ajax.BeginForm do a full submit and not Ajax Html submit.

$('a[href*="://"]').attr('target','_blank');

Now all links that contain ‘://’ (http://, https://, ftp://, etc) will open in a new window!

In order to control caching for linked objects (scripts, css, images, etc) you need to pass them through a loader that calls this function before kicking out the file’s content. Or, you modify the tags (see below) to prevent caching. This method will impact load times as the example image and stylesheet are never cached…

<link rel="stylesheet" href="mystylesheet.css?<?php echo time(); ?>">
<img src="myimage.jpg?<?php echo time(); ?>">

Try it like this…

$config = array(
    'source_image' => 'usermedia/pictures/currently_processing/' . $uploaded['file_name'],
    'new_image' => $userid . '_' . time() . '.jpg'
);
$this->load->library('image_lib', $config);
$this->image_lib->convert();

The following methods natively support $config['new_image']

$this->image_lib->resize()
$this->image_lib->crop()
$this->image_lib->rotate()
$this->image_lib->watermark()

Feel free to modify the convert() method to ‘new_image’ by examining it’s usage in the above methods.

Note: I can revisit the code and add renaming support, but it will have to be when I have some more free time.

Picture::convert(array(
‘source_image’ => ‘usermedia/pictures/currently_processing/’ . $uploaded['file_name'],
));

So, I upload the image first into the directory called “currently_processing”, and then I convert it to .JPG using your function. I was hoping I’d be able to rename the converted version to the ID of the user, concatenated with an underscore, concatenated with the current UNIX timestamp, concatenated with “.jpg”, which would look something like this: “7442_1319280674.jpg”.

However, I am unsure how this would be done using your function.

Note: My example assumes the first button is the “default” (eg: Ok, Save, etc), so adjusting the selectors may be necessary if you need to fire the action of an alternate button

This is the code that helped me out

$(‘.ui-dialog-buttonpane button:first’).click();

tricky I say, very tricky

// manually preload an image
preloadedImages[preloadedImages.length] = new Image();
preloadedImages[preloadedImages.length - 1].src = 'path/to/someimage.gif';
preloadedImages[preloadedImages.length] = new Image();
preloadedImages[preloadedImages.length - 1].src = 'path/to/anotherimage.jpg';
