If you want to get the current URL in CodeIgniter then you can use uri_string from URI Class.
$this->uri->uri_string()
link_tag is an interesting helper function introduced recently in CodeIgniter that helps you build link HTML tags to include CSS files but also feeds or favicons in a header.
The helper function documentation is quite explanatory and you can see it here.
In particular, if you are planning to use a similar function for Javascript files, please check this forum post. A custom helper function that helps using the same approach but for JS files instead.
But if you want to go one step ahead, also notice that you can get a performance improvement by combining external resources in one single file. In CodeIgniter you can also do that, for example using the approach to combine JS and CSS files.
CSVReader is a library for CodeIgniter that can help you importing CSV files into database using CodeIgniter framework. The library uses fgetcsv function from PHP to get the content from CSV file and then iterates over the records returning an array as result.
Then, you can iterate the parsed results from the CSV file to insert them into the database easily using a foreach statement. For example, you can refer to Clooner’s proposal here.
This CSVReader library can be really helpful in case you need to import large CSV files into the database using a CodeIgniter application, but also can be useful to import Excel files into the database or any other database file that can be exported to CSV. For Excel, you can export the results using comma separated values and then use this approach.
MD_Image is a CodeIgniter Library that allows you to resize and crop images in CodeIgniter keeping a desired ratio. You can see the original thread here.
If you want to display avatar images in your CodeIgniter application, you can use this Gravatar helper that contains a simple function to retrieve the Gravatar image source for a given email.
The Gravatar helper was created by Dave_C as mentioned in Codeigniter Forums.
By using this helper you can easily integrate your application with Gravatars like this:
Follow the installation steps described here, and then just load the helper as usual and put this code in your view page passing the desired email as first parameter.
<?php echo gravatar( "you@domain.com" ); ?>
