Very difficult. The value is hard coded in wp-admin/js/post.js
. See wp-admin/js/post.dev.js
tagBox.init()
for more readable code:
$(this).suggest( ajaxurl + '?action=ajax-tag-search&tax=' + tax,
{
delay: 500, minchars: 2, multiple: true, multipleSep: postL10n.comma + ' '
} );
The only solution I can see: Unregister the script with the handle 'post'
(see wp-includes/script-loader.php
) and register a custom copy where you change the minchars
value.
