Help with Joomla params

[Giorgi_964758]

Hi ! I'm doing template on Joomla 3.7. I'm reading Dan Rahmel - Advanced Joomla. And I met the problem. I don't understand what I'm doing wrong. I'm creating a param (for Inject jQuery library reference into head section) in templateDetail.xml file in sublime text 3.

Code: Select all

<config>
				<fields name="params">
					<fieldset name="advanced">
						<field name="include_jquery" type="radio"
							default="1" label="Include jQuery"
							description="Inject jQuery library reference into head section">
							<option value="1">Yes</option>
							<option value="0">No</option>
						  <?php if($this->params->get('include_jquery')): ?>
							<script type="text/javascript"
						  	  src="<?php echo $template_path;?>/js/jquery-3.2.1.min.js"></script>
						  <?php endif;?>
						</field>

						<field name="background_color" type="text" default="white"
							label="Background color"
							description="Set the background color of the body tag"
							filter="string" />
					</fieldset>
				</fields>
			</config>

PHP tag colored in red. Why ? Please see the picture

You are using php in an .xml file. I am pretty sure that's not allowed.

Attached fragment from the book

you are mixed 2 different files.
first part was about xml (no js/php allowed), second - its template index.php

Yes. From "Figure 3-10" is about how to show params in index.php of template.
