Introduce esc_attr() reverted function

[alexvorn2]

A function that will decode

< > & " '

to

< > & " '

(less than, greater than, ampersand, double quote, single quote).

Sounds like you're after html_entity_decode()

Replying to dd32:

Sounds like you're after html_entity_decode()

this function does not work for single quote.

If a such function exists - esc_attr() then logically it should also exist a reverted function like capture_attr() or cap_attr() for such task.

function esc_attr():

function esc_attr( $text ) {
	$safe_text = wp_check_invalid_utf8( $text );
	$safe_text = _wp_specialchars( $safe_text, ENT_QUOTES );
	return apply_filters( 'attribute_escape', $safe_text, $text );
}

function cap_attr():

function cap_attr( $text ) {
	$safe_text = wp_specialchars_decode( $text, ENT_QUOTES );
	return apply_filters( 'attribute_capture', $safe_text, $text );
}

No?

esc_attr() is designed for escaping data to be used in HTML attributes, There are very rare cases where you should need to convert the data back, If you're saving something using esc_attr() and then later need to convert it back, you're probably doing it wrong, or using the wrong form of sanitization.

When used in it's compatibility mode (default) it doesn't, however, like most PHP functions, it has a range of configuration parameters.

echo html_entity_decode( '&lt; &gt; &amp; &quot; &#039;', ENT_QUOTES ); // outputs < > & " '
