Moodle: custom CSS in Essential theme

When you want to custom a moodle instance, you could need to modify Essential theme, for example, I don't want to see headers in SCORM content. The best option is use customcss property.

We go to admin/settings.php?section=theme_essential_generic in our site and we search for customcss textarea. To avoid seeing headers in SCORM, we add:

#page-mod-scorm-player div[role=main] h2 {display: none;}
#page-mod-scorm-player header[role=banner] {display: none;}


Best regards!

Install MAMP + Laravel 4

Hello,

Today I installed in Mac OS X (10.7.5) server MAMP (3.0.4) + Laravel 4. I did these steps:
  • First, I downloaded and installed MAMP from http://www.mamp.info. I modified default conf changin ports to 80 and 3306.
  • Next, I modified file bash_profile (vim ~/.bash_profile): export PATH=/Applications/MAMP/bin/php/php5.5.10/bin:$PATH alias composer="php /usr/bin/composer.phar" alias laravel="~/.composer/vendor/bin/laravel"
  • Then, I reset terminal and downloaded composer: curl -sS getcomposer.org/installer | php.
  • Next step, move composer.phar: sudo mv composer.phar /usr/bin/
  • I donwloaded Laravel 4 installer: composer global require "laravel/installer=~1.1"
  • I went to /Applications/MAMP/htdocs and I created a new Laravel project: laravel new ibancardonasubiela.tk
  • Then, I created a new virtual host in my MAMP. To do that, I edited file Applications/MAMP/conf/apache/httpd.conf and I uncommented "Include /Applications/MAMP/conf/apache/extra/httpd-vhosts.conf". Then I edited file Applications/MAMP/conf/apache/extra/httpd-vhosts.conf and I added: <VirtualHost *:80>                     DocumentRoot /Applications/MAMP/htdocs/ibancardonasubiela.tk/public                                   ServerName wwww.ibancardonasubiela.local </VirtualHost>
  • I restarted MAMP service.
  • I edited file  /etc/hosts (sudo vim /etc/hosts) adding: 127.0.0.1 www.ibancardonasubiela.local
  • And, finally, Laravel installed in http://www.ibancardonasubiela.local/

Moodle: Delete one file in moodle filesystem

Hola,

After seeing how to add files and how to list them. Today we will see how to delete them:

$fs = get_file_storage();

// Prepare file record object
$fileinfo = array(
'component' => 'backup',
'filearea' => 'course',
'itemid' => 0,
'contextid' => 0,
'filepath' => '/',
'filename' => 'filename.xlsx'
); 


// Get file
$file = $fs->get_file($fileinfo['contextid'], $fileinfo['component'], $fileinfo['filearea'], $fileinfo['itemid'], $fileinfo['filepath'],
$fileinfo['filename']);

// Delete it if it exists
if ($file) {
if ($file->delete()) {
return true;
} else {
return false;
}
}


Best regards!

Moodle: list files in moodle filesystem

Hello,

Last day we saw how to create an excel file in modle: http://icsbcn.blogspot.com/2014/11/moodle-create-and-save-excel-file-in.html

If we want to list that files, we can do this:

// List excel files
$table = new html_table();
$table->head = array('filename', 'filedate', 'filesize', '');
$table->align = array('left', 'left', 'left','left');


// Get files
$fs = get_file_storage();
$files = $fs->get_area_files(0,  'backup', 'course', 0, 'timemodified DESC', false);
foreach ($files as $file) {
$filename = $file->get_filename();


$row = array();
$row[] = $filename; // filename
$row[] = date('d/m/Y H:i:s', $file->get_timecreated()); // creation date
$row[] = $this->formatSizeUnits($file->get_filesize()); // file size as human view


// Download link
$url = moodle_url::make_pluginfile_url($file->get_contextid(), $file->get_component(), $file->get_filearea(), $file->get_itemid(), $file->get_filepath(), $filename);
$row[] = html_writer::link($url, get_string('downloadfile', 'moodle'));


$table->data[] = $row;
}
// End get files


$content .= html_writer::start_tag('div', array('id' => 'list_files'));
$content .= html_writer::table($table);
$content .= html_writer::end_tag('div');
// End list excel files

Best regards!

Moodle: Create and save an excel file in moodle filesystem

Hello,

Moodle filesystem is powerful but it's hard to understand too. In this code we will see how to create an excel file and save it in the moodle filesystem:

Documentation:
https://docs.moodle.org/dev/File_API_internals
https://docs.moodle.org/dev/File_API

// Create excel file
require_once("$CFG->libdir/phpexcel/PHPExcel.php");
$filenameTmp = tempnam(sys_get_temp_dir(), time());

$objPHPExcel = new PHPExcel();

// Excel metadata $objPHPExcel->getProperties()->setCreator("www.ibancardonasubiela.tk") ->setLastModifiedBy("www.ibancardonasubiela.tk") ->setTitle("www.ibancardonasubiela.tk") ->setSubject("www.ibancardonasubiela.tk") ->setDescription("www.ibancardonasubiela.tk")

// Crear the first sheet

$objPHPExcel->setActiveSheetIndex(0);
$objPHPExcel->getActiveSheet()->setTitle("www.ibancardonasubiela.tk");


// Header
$arrayHeader = array('aaa', 'bbb');
$countHeader = count($arrayHeader);
foreach ($arrayHeader as $pos => $value) {
$excelLetter = PHPExcel_Cell::stringFromColumnIndex($pos);
$objPHPExcel->getActiveSheet()->getStyle($excelLetter.'1')->getFont()->setSize(14);
$objPHPExcel->getActiveSheet()->getStyle($excelLetter.'1')->getFont()->setBold(true);
$objPHPExcel->getActiveSheet()->setCellValue($excelLetter.'1', $value);
$objPHPExcel->getActiveSheet()->getColumnDimension($excelLetter)->setAutoSize(true);
}

// Add content

// Save excel in a temporal file
$objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel);
$objWriter->save($filenameTmp);

// Copy excel to moodle filesystem
$fs = get_file_storage();
$file_record = array(
'contextid' => 0,
'component' => 'backup', // "mod_forum", "course", "mod_assignment", "backup"...
'filearea' => 'course', // "submissions", "intro" and "content" , "blogs","userfiles"...
'itemid' => 0,
'filepath' => '/',
'timecreated' => time(),
'timemodified' => time(),
'filename' => 'excel'.'_'.time().'.xlsx'
);
$fs->create_file_from_pathname($file_record, $filenameTmp);

// Delete temp file
unlink($filenameTmp);


Best regards!

Datatables in a bootstrap 3 modal window

Datatables is an important javascript plugin for jQuery to improve behaviour of our website tables.

Recently I saw that using tables (datatables tables) in a bootstrap modal window, after init the table, part of table was shown outside of the window.

I'm using version 1.9.3 of datatables, version 1.10.2 of jQuery and versio 3.0.1 of bootstrap.

My solution was use "fnDrawCallback" function in order to change the window's size after "drawing" the table:

tableObject = $('#idTable').dataTable({
"bProcessing": true,
"bServerSide": true,
"sAjaxSource": "ajaxSource",
"fnDrawCallback": function( oSettings ) {
$('#idTable').find('.modal-dialog').css(
{
width:'auto',
height:'auto',
'max-height':'100%'
});
},
'aaSorting': [[ 0, "asc" ]]
});


Kind regards!

Moodle: get top category from course data

Hello!

If we have course data and we want to get top category from that, we can do this:

$category = $DB->get_record('course_categories', array('id' => $courseObj->category));
$arrCats = explode("/", ($category->path));
$topCategory = $DB->get_record('course_categories', array('id' => intval($arrCats[1])));


Best regards!
