Adding readonly function to wp-includes/general-template.php

A quite simple improvement, really.

Just like the checked, selected and disabled function, readonly would be a shortcut to checked_selected_helper.

I was doing a theme option page and realized that disabling fields removes the data from the data submission.

I have a bunch of fields that gets used (or not) in the theme, depending on a on/off switch. At first, depending on the switch, I was disabling the fields, but all the data is removed on submit if the switch is at off. Meaning that the user would have to reenter every fields if he wants to activate the functionality.

Putting the fields on readonly gives a nice feedback to the user that those fields are not use, depending on the switch, AND the data is kept if the user changes his mind.

So, here's the patch.

 * Outputs the html readonly attribute.
 * Compares the first two arguments and if identical marks as readonly
 * @since 3.1.#
 * @param mixed $disabled One of the values to compare
 * @param mixed $current (true) The other value to compare if not just true
 * @param bool $echo Whether to echo or just return the string
 * @return string html attribute or empty string
function readonly( $readonly, $current = true, $echo = true ) {
    return __checked_selected_helper( $readonly, $current, $echo, 'readonly' );

The function name is overly broad, what about renaming the function to output_html_readonly_attribute()?

Next to that what is the need of the aliasing here? You could do in your own plugin which would spare you the typing as well (or even better you can create a DSL and then even more easily write your code).

Going to echo azaozz's sentiment on #20110:

Don't see a point in replacing simple HTML attributes with PHP functions that generate them. This type of functions would always need lots of args to be able to cover the more common cases which makes the code a lot harder to read. On top of that they usually don't cover all possible cases making them redundant.

Can we try again? Seems like a useful thing. We have disabled which is almost the same but readonly will submit the fields. I think there's a legitimate use case here. It's not like we're asking for required() :)

Replying to soulseekah:

Seems like a useful thing. We have disabled which is almost the same but readonly will submit the fields.

Agreed, readonly isn't that much different from disabled, makes sense to have both for consistency.
