SECURING OUTPUT
Securing output is the process of escaping output data.
This is done to prevent XSS attack and also to make sure that the data is displayed
the way the user expects it to be.
What is Escaping?
Escaping converts the special HTML characters to HTML entities so that they are
displayed, instead of being executed.
Escaping functions are:
------------------------------------------------
esc_html()
This functions escapes HTML specific characters.
esc_textarea()
Use esc_textarea() instead of esc_html() while displays text in textarea. Because
esc_textarea() can double encode entities.
esc_attr()
This function encodes the angularBrackets, &, " and ' characters. It will never double encode
entities. This function is used to escape the value of HTML tags attributes.
esc_url()
URLs can also contain JavaScript code in them. So, if you want to display a URL or a
complete a tag, then you should escape the href attribute or else it can cause an
XSS attack.
