I've written a shortcode and its functioning like it should. Now the hard part:
I would like to show the user a preview already in the tinyMCE editor. Loading CSS in the editor is not a problem for me, but i would love to know if it is possible to already process the shortcode within TinyMCE.
Thanks!
WordPress is bundled with the open source HTML WYSIWYG editor TinyMCE by Moxiecode Systems, AB.
Log in to your WordPress Dashboard, click Plugins, then Add New. Search for the Advanced TinyMCE Configuration plugin, then click Install Now. Once the plugin is installed, click Activate.
This plugin adds a preview button to the toolbar. Pressing the button opens a dialog box showing the current content in a preview mode. It also adds a menu item Preview under the File and View menu dropdowns.
Use the checkbox to toggle between the "design" and "readonly" modes.
Let the code talk: I'll put a code to add a visual icon for highlight content word(s) shortcode, and you can then implement any other shortcode you want with the same logic,
class spot_shortcodes {
function spot_shortcodes()
{
add_action('init', array(&$this, 'init'));
}
function init(){
// Enable shortcodes in text widgets
add_filter( 'widget_text', 'do_shortcode' );
// Fix for large posts, http://core.trac.wordpress.org/ticket/8553
@ini_set( 'pcre.backtrack_limit', 500000 );
// init process for button control
add_filter( 'tiny_mce_version', 'my_refresh_mce');
// Add only in Rich Editor mode
if ( get_user_option('rich_editing') == 'true') {
add_filter('mce_buttons_3', array(&$this, 'register_highlight_button'));
}
}
// Add your button plugin js code to tinyMCE
// codex: wp_register_script( $handle, $src, $deps, $ver, $in_footer );
wp_register_script( 'effects-highlight', SPOT_SHORTCODES_URL . '/js/jquery.effects.highlight.js', false ,SPOT_SHORTCODES_URL, true );
function add_youtube_button() {
// Don't bother doing this stuff if the current user lacks permissions
if ( ! current_user_can('edit_posts') && ! current_user_can('edit_pages') )
return;
// Add only in Rich Editor mode
if ( get_user_option('rich_editing') == 'true') {
add_filter("mce_external_plugins", array(&$this, "add_youtube_tinymce_plugin"));
add_filter('mce_buttons', array(&$this, 'register_highlight_button'));
}
}
// function to register you button to tinyMCE dashboard
function register_highlight_button($buttons) {
array_push($buttons, "|", 'highlight_button');
return $buttons;
}
function add_youtube_tinymce_plugin($plugin_array) {
// your icon image(highlight.png) which will be displayed in the tinyMCE dashboard
$plugin_array['highlight'] = SPOT_TINYMCE_URL . '/icons-lib-custom.js';
return $plugin_array;
}
} // class end
// Finally make an object from your button
$spot_shortcodes = new spot_shortcodes();
Our js code for the highlight button option make an dot js file put the followin code in it and put it in the tinyMCE plugin directory
// dont forget to change the paths
tinymce.create('tinymce.plugins.highlight', {
// creates control instances based on the control's id.
// our button's id is "highlight_button"
createControl : function(id, controlManageradel) {
if (id == 'highlight_button') {
// creates the button
var button = controlManageradel.createButton('highlight', {
title : 'Add a Hightlight Text', // title of the button
image :spotShortcodes.plugin_folder +"/tinymce/images/highlight.png", // path to the button's image
onclick : function() {
// triggers the thickhighlight
var width = jQuery(window).width(), H = jQuery(window).height(), W = ( 720 < width ) ? 720 : width;
W = W - 80;
H = H - 84;
tb_show( 'Insert text box shortcode', '#TB_inline?width=' + W + '&height=' + H + '&inlineId=highlight-form' );
}
});
return button;
}
return null;
}
});
// registers the plugin. DON'T MISS THIS STEP!!!
tinymce.PluginManager.add('highlight', tinymce.plugins.highlight);
// executes this when the DOM is ready
jQuery(function(){
// creates a form to be displayed everytime the button is clicked
// you should achieve this using AJAX instead of direct html code like this
var form = jQuery('<div id="highlight-form"><table id="highlight-table" class="form-table" style="text-align: left">\
\
\
<tr>\
<th><label class="title" for="highlight-bg">Highlight color</label></th>\
<td><select name="bg" id="highlight-bg">\
<option value="#f02d33">Red</option>\
<option value="#b6bbbd">Grey</option>\

<option value="#fcc016">Yellow</option>\
<option value="#f65e0e">Orange</option>\
</select><br />\
<div class="info"><small>Select box type.</small></div></td>\

<tr>\
<th><label class="title" for="highlight-contet">Conent</label></th>\
<td><textarea rows="7"\ cols="45"name="content" id="highlight-content">hightlight text</textarea>\
<br />\
<div><small>this text displayed in box.</small></div></td>\
</tr>\
</table>\
<p class="submit">\
<input type="button" id="highlight-submit" class="button-primary" value="Insert shortcode" name="submit" style=" margin: 10px 150px 50px; float:left;"/>\
</p>\
</div>');
var table = form.find('table');
form.appendTo('body').hide();
// handles the click event of the submit button
form.find('#highlight-submit').click(function(){
// defines the options and their default values
// again, this is not the most elegant way to do this
// but well, this gets the job done nonetheless
var options = {
'bg' : '#f02d33',
'content' : 'hightlight text',
};
var shortcode = '[highlight ';
for( var index in options) {
var value = table.find('#highlight-' + index).val();
// attaches the attribute to the shortcode only if it's different from the default value
if ( value !== options[index] & index !== 'content')
shortcode += ' ' + index + '="' + value + '"';
}
shortcode += ']'+ value + '[/highlight]'
// inserts the shortcode into the active editor
tinyMCE.activeEditor.execCommand('mceInsertContent', 0, shortcode);
// closes Thickhighlight
tb_remove();
});
});
