How to Make Simple Custom Page Moodle (moodle plugins chapter 1)

 The first thing you have to know to become a Moodle developer is know the program structure in Moodle.

And a simple example is to create a custom page that is connected with Moodle application.

There are several variables of the Moodle system that you need to know.

$CFG = for information website like baseurl etc.
$DB = conntecting to database moodle.
$OUTPUT = for calling strutur in template moodle like header footer.
$PAGE= set information page like title breadcrump etc.

I will try to practice making a simple page with the structure we already know . Create a new folder in the root directory of moodle for example newcustompage and create a file with the name index.php put this code :

<?php

//CALL CONFIG DATABASE
require_once('../config.php');


//TITLE AND BREADCRUMB
$PAGE->set_title('New Custom Page');

$PAGE->navbar->add("New Custom Page");

//CALL HEADER PAGE
echo $OUTPUT->header();

//LINE FOR CONTENT PAGE
echo "Content";
echo $CFG->wwwroot;


//CALL FOOTER PAGE
echo $OUTPUT->footer();

Then try to run

Next I try to display data from the database into the page. Before that we must know how to use the $DB variable.

// SELECT multiple data
$DB->get_records_sql("SELECT * FROM {course}");

//SELECT row
$DB->get_record_sql("SELECT * FROM {course} WHERE id=1");

And let's to try

<?php

//CALL CONFIG DATABASE
require_once('../config.php');


//TITLE AND BREADCRUMB
$PAGE->set_title('New Custom Page');

$PAGE->navbar->add("New Custom Page");

//CALL HEADER PAGE
echo $OUTPUT->header();

//LINE FOR CONTENT PAGE

//SELECT multiple data
$data = $DB->get_records_sql("SELECT * FROM {course} LIMIT 5");

$content = '<table class="table">
<tr>
<td>ID COURSE</td>
<td>COURSE NAME</td>
</tr>';

foreach ($data as $key => $value) {
	

	$content .= '

	<tr>
	<td>'.$value->id.'</td>
	<td>'.$value->fullname.'</td>
	</tr>';

}

$content .='

</table>';

echo $content;


//SELECT row

$data = $DB->get_record_sql("SELECT * FROM {course} WHERE id=1");

echo $data->fullname;


//CALL FOOTER PAGE
echo $OUTPUT->footer();

If you want to develop better please go to the official Moodle website and read the documentation.

Good luck !
