如何使用Codeigniter自动添加？

Question

I want to apply addslashes() to all the post elements got through

$this->input->post('my_var');

How can I do that ? Is there any feature like filters under wordpress for this ?

I think you want something global. My idea is to edit the global post function in the codeigniter to use addslashes on everything. You can find that function in:

/yourfolder/system/core/Input.php

You can escape it by setting it global.

function post($index = NULL, $xss_clean = FALSE)
    {
        // Check if a field has been provided
        if ($index === NULL AND ! empty($_POST))
        {
            $post = array();

            // Loop through the full _POST array and return it
            foreach (array_keys($_POST) as $key)
            {
                $post[$key] = addslashes($this->_fetch_from_array($_POST, $key, $xss_clean));
            }
            return $post;
        }

        return addslashes($this->_fetch_from_array($_POST, $index, $xss_clean));
    }

Although I don't really find it as good solution to modify the global functions this should do the trick in your case.

Edit: I see that input->post already does that and you would not need to add that function additionally.
