This function always returns TRUE whether or not it was able to save the image. Since the internal calls to imagegif(), imagejpg() and imagepng() are silenced in this function, no error is displayed. Then the function defaults to returning TRUE at the end of its call, so the function that called it has no idea that it wasn't able to do its job.

How to reproduce:
Attempt to resize an image to a non-existent folder. The resize() operation will pass with flying colors, but no resized image will be found.

Possible solutions:

1. Validate that the destination path is writeable before calling this function.
or
2. Return FALSE from this function and handle that in the calling code.

Note: this is not a function called directly from outside of the Image_lib. It's called internally, so the only way for a user of the library to fix it would be subclass the Image_lib class and put the fix in the subclass. The permanent fix needs to be part of a CodeIgniter update.

The user guide states the following:

If you prefer not to set preferences using the above method, you can instead put them into a config file. Simply create a new file called image_lib.php, add the $config array in that file. Then save the file in: config/image_lib.php and it will be used automatically. You will NOT need to use the $this->image_lib->initialize function if you save your preferences in a config file.


Which is great because you can seprate all your config values. Problem is what do you do if you want to store the config values for more than one image manipulation script?

Can you use a multi dimensional array for the $config

I tried to use my own config file and it didnt work, I had a controller called image_gallery.php and created a cofig file under the config folder called image_gallery.php I then loaded it, and the values were available using $this->config->item() but they were not automatically available like they are when you set them in a config file called image_lib.php.

Am I correct? has anyone else noticed this? Or did I make a mistake somewhere?

I've been working on this for a day and a half now and I'm about to pull my hair out. I know it has to be something simple, or I would have been able to work it out by now.

Basically, I'm using ajax to validate form fields inline and am hiding the submit button until all fields that are required are filled in (and validated when required), the problem is that $this->input->post('field') will absolutely *NOT* validate if empty. In fact, rather the opposite, like so:

What is the best way to trigger upload error messages? Like stop the upload process, if file is too large or wrong type? I was trying some things like if (!$this->upload->do_upload()), but that was causing all sorts of problems with my overall process of the controller, as well the upload is not required. Any ideas, or did I miss something in previous posts?

I am having considerable trouble getting my file field to be picked up by my controller. It is like the name field is not sending its value over to the controller. Every time I submit the form It gives me the same, "please fill in your file selection field". Ahh! Why does this happen?

If anyone has an explanation for this I would be very thankful.

Here is the controller:

I currently have a system where a user can update their name and avatar. The upload works great with images, etc, but if I do not upload an image, I get an error saying no file was chosen. Sometimes the user might just update their web address. What can I use to check "if there is a file being uploaded, then run my upload process" ?

Any help would be greatly appreciated.

Hi,

Before starting something, I am trying to plan how I will do that.

I need to do a blog where different registred users can add word tags to their posts, so when a visitor click on a tag he can retrieve all posts concerning a specific tag. Unfortunately I can't use a solution like wordpress or EE, I must to build it from scratch.

So my question is:
How would you plan the Database schema to manage this tags?

Hi

I am getting an error while running file upload function. I am uploading the file format same as defined under 'allowed_types'/'mimetypes' ie gif,png,jpg.

Also, if I run it independently then it works fine but when I embed it in my code then the following error occurs.

The error says:

Array ( [error] =>

The filetype you are attempting to upload is not allowed
)

My Code is: (Under 'controller' directory)

$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '100';
$config['max_width'] = '1024';
$config['max_height'] = '768';

$this->load->library('upload', $config);

if ( ! $this->upload->do_upload())
{
$error = array('error' => $this->upload->display_errors());

print_r($error);
}
else
{
$data = array('upload_data' => $this->upload->data());

echo "success";
}
