Tips: Protect method to remove empty i tag with CKEditor4 plugin

Tue, 14 Oct 2014 20:38:40 +0000

We use sometimes i tag on Bootstrap themes such as FlexArmor2 for vector icons (e.g. font awesome, GLYPHICONS).

Example of HTML code:

<i class="fa fa-book"></i>

However, because CKEditor removes empty tag, i tag is lost.

Solution1 (recommended):

You can evade this by adding a lower line to CKEditor4 Other configuration option.

protectedSource:[/<i[^>]*><\/i>/g],

Solution2:

You can deal by adding space.

<i class="fa fa-book"> </i>

Reference:

CKEditor4
CkEditor4 for admin <<< This Tips will be particularly effective in this plugin.

Why does function q_view($q_view) checks if (!empty($q_view))?

Sun, 15 Sep 2013 14:53:17 +0000

qa-theme-base.php

function q_view($q_view) {

if (!empty($q_view)) {

Why do we check if q_view is not empty? I cannot think of any scenario where it is not empty, as question view needs to have question content?

qa_postmetas Table: Why adding record if empty

Sun, 07 Jul 2013 14:58:47 +0000

Just wonder why it is creating record for qa_q_extra in qa_postmetas even if field is empty. Isn't that better to add record only if question has qa_q_extra value? Or any reson to store empty record? Just curious to know.

Update Plugin: Empty Tag Cleaner (V1.0)

Tue, 28 May 2013 00:17:49 +0000

This is tiny tool plugin for removing empty HTML tag. This plugin removes also HTML tag including white-space and new-line in text-node as empty tag. Although empty tag can be erased by CSS, "empty" pseudo class of CSS3 does not work effectively, when the text node of tag has whitespace or newline. This plugin deletes empty tag, after removing whitespace and newline of tag which were specified in option by jQuery.

Why empty tables in database (qa_postmetas, qa_tagmetas, qa_usernotices)?

Fri, 24 May 2013 07:49:05 +0000

By curiosity, which of these tables (having 0 rows/entries) can be considered unnecessary?

I know that some were created by plugins, some are there be default:

qa_categories ← I am not using categories, that's why this is empty.

qa_categorymetas ← same

qa_messages ← I am not using PN that's why this is empty.

qa_postmetas ← what for?

qa_tagmetas ← what for?

qa_usermetas ← "Plugins etc... can use qa_usermetas for any meta information relating to users - see qa-db-metas.php." Clarified.

qa_usernotices ← what for?

Why meta tables are empty?

Thu, 16 Aug 2012 05:27:02 +0000

These tables
