In CodeIgniter, you can use the xss_clean()
function to sanitize input data and prevent cross-site scripting (XSS) attacks. This function is provided by the Security
library, which is loaded by default in CodeIgniter.
Here's an example of how to use xss_clean()
:
1 2 |
$input = $this->input->post('input_field'); $clean_input = $this->security->xss_clean($input); |
The xss_clean()
function takes a string as an argument and returns the sanitized version of the string. It removes any potentially malicious code or scripts from the input data.
You can also use the xss_clean()
function on arrays of data by using the xss_clean_array()
function, like this:
1 2 |
$input_array = $this->input->post(); $clean_input_array = $this->security->xss_clean_array($input_array); |
It's important to note that the xss_clean()
function is not 100% foolproof and cannot completely protect against all types of XSS attacks. It's always a good idea to also validate and filter your input data as part of your overall security strategy.
