Using custom characters in JCE Editor can be challenging, especially if you want to use symbols, not on the JCEs default list. There are two ways to do this.

Special characters are often used in content to show something, but could you please explain how a field is inserted into an article? You know it's by inserting curly brackets { and }, but you can't insert the field number in between because you will then show the field instead of the text.

The two methods

There are two ways to do this. One is by overriding/adding the characters to the Character Map in JCE; how come this method requires you to add each code separately in each of your JCE profiles using an HTML entity? Using this way, you must ensure that JCE does not strip your code. The other way is by using CSS and pseudo-elements

Method 1: Override the Character Map

 Adding special characters to the Character Map is very time-consuming. First, you'll need to find the HTML entities you want to add. Here is a list of them. Now go into your JCE profile of choice; go into "Plugin Parameters" and find Character Map. There you need to add all your entities.

Method 2

<span class="special-chars curly-backets">field 1</span>

// Curly Brackets
span.special-chars {
	display: inline-block;
	background-color: 777;
}

span.curly-brackets:before {
	content: "{";
}

span.curly-brackets:after {
	content: "}";
}

Now we will add a CSS file to JCE.

 Go to Components → JCE Editor → Profiles → [YOUR PROFILE] usually "Default" → Editors Parameters ↔ Typography → Write your file path and name in "Custom CSS Files"

Now add the styles to the Plugin Parameters.

 Go into your Profile (as above) → Plugin Parameters → Style Select (scroll down to find)

Now you can add the Styles directly into

Here you add your styles

There are three places to make sure you add the styles. Give it a Name, Tag, and Classes (for Tag, it is helpful to use "span").

In your article, select the test to have, like the Styles dropdown, and your "Curly Brackets" will appear.

REMEMBER TO ADD YOUR STYLES TO THE TEMPLATE!

JCE Editor is more than a basic Editor for Joomla. You can give access to specific folders on the ROOT or even subfolders using the “Filesystem” in the JCE Profiles.

Published: 09 July 2023

Icons have a significant visual effect to have on your website. Did you know that using an icon as a Custom Field is possible? - Creating an override for the Field layout is done in minutes.

Since Font Awesome is included in Joomla's Cassiopeia template, we will use a template override for the Field layout.

 How do we create a Joomla override in Joomla 4?

Creating overrides in Joomla 4 is relatively easy. It is easier if you can read code and know HTML. Just follow these steps:

Go to System  Site Templates  [YOUR TEMPLATE NAME] Details and Files

Select the "Site Template" to go into the area for creating overrides of Joomla 4. 

Joomla 4 left menu

Select "System" from the left menu. 

What are the differences between "Site Templates" and "Site Template Styles"?

The difference between Site Templates and Site Template Styles is that the overrides for the Template that is put on the Site Templates place, here you put all your customization of the site. The Styles are set in the separate Site Template Styles, which you only use to change the site's primary colors and add a custom logo and the template's name. 

Joomla 4 select "Site Templates"

This opens the place where you create the overrides. There is a selection called "Create Overrides"; go into it.

You will now come into the selection area where all your Modules, Components, Plugins, and Layout overrides are shown.

 Now let's create the override

The override we are looking for is a "Layout"-override, and the field, this is located under Layouts ⇒ com_fields, select "Field".

Now go into the editor under HTML ⇒ layouts ⇒ com_fields ⇒ field ⇒ render.php. 

REMEMBER TO RENAME THE render.php FILE!

Original code for Custom Field

defined('_JEXEC') or die;

use Joomla\CMS\Language\Text;

if (!array_key_exists('field', $displayData)) {
    return;
}

$field = $displayData['field'];
$label = Text::_($field->label);
$value = $field->value;

if ($value == '') {
    return;
}

<?php if ($showLabel == 1) : ?>
    <span class="field-label <?php echo $labelClass; ?>"><?php echo htmlentities($label, ENT_QUOTES | ENT_IGNORE, 'UTF-8'); ?>: </span>
<?php endif; ?>
<?php if ($prefix) : ?>
    <span class="field-prefix"><?php echo htmlentities($prefix, ENT_QUOTES | ENT_IGNORE, 'UTF-8'); ?></span>

<?php if ($suffix) : ?>
    <span class="field-suffix"><?php echo htmlentities($suffix, ENT_QUOTES | ENT_IGNORE, 'UTF-8'); ?></span>
<?php endif; ?>

Code for Font Awesome Custom Field

<?php

 */

defined('_JEXEC') or die;

use Joomla\CMS\Language\Text;

if (!array_key_exists('field', $displayData)) {
    return;
}

$field = $displayData['field'];
$label = Text::_($field->label);
$value = $field->value;
$showLabel = $field->params->get('showlabel');
$prefix = Text::plural($field->params->get('prefix'), $value);
$suffix = Text::plural($field->params->get('suffix'), $value);
$labelClass = $field->params->get('label_render_class');
$valueClass = $field->params->get('value_render_class');

if ($value == '') {
    return;
}

?>
<?php if ($showLabel == 1) : ?>
    <span class="field-label <?php echo $labelClass; ?>"><?php echo htmlentities($label, ENT_QUOTES | ENT_IGNORE, 'UTF-8'); ?>: </span>
<?php endif; ?>
<?php if ($prefix) : ?>
    <span class="field-prefix"><?php echo htmlentities($prefix, ENT_QUOTES | ENT_IGNORE, 'UTF-8'); ?></span>
<?php endif; ?>
<span class="field-value <?php echo $valueClass; ?>"><i class="fa fa-<?php echo $value; ?>"></i></span>
<?php if ($suffix) : ?>
    <span class="field-suffix"><?php echo htmlentities($suffix, ENT_QUOTES | ENT_IGNORE, 'UTF-8'); ?></span>
<?php endif; ?>

 Now Create a field

The best field to use is the "radio-button" field. On the options tab - Go to layouts, and select the desired override.
