I want to share my experience regarding display submitted images on the review page for the quiz if there is any submission (Specifically auto grade essay question or could be used on regular essay question as well)
we are using version 3.5.7 moodle installed on cpanel for your information.
you need to change this file called "renderer.php" under Moodle/question/type/essayautograde(or essay)
Before
public function files_read_only(question_attempt $qa, question_display_options $options) {
$files = $qa->get_last_qt_files('attachments', $options->context->id);
$output = array();
foreach ($files as $file) {
$output[] = html_writer::tag('p', html_writer::link($qa->get_response_file_url($file),
$this->output->pix_icon(file_file_icon($file), get_mimetype_description($file),
'moodle', array('class' => 'icon')) . ' ' . s($file->get_filename())));
}
return implode($output);
}
After
public function files_read_only(question_attempt $qa, question_display_options $options) {
$files = $qa->get_last_qt_files('attachments', $options->context->id);
$output = array();
foreach ($files as $file) {
$type=get_mimetype_description($file);
$extensions=array('Image (JPEG)','Image (PNG)','Image (BMP)','Image (GIF)','Image (PICT)','Image (SVG+XML)','Image (TIFF)');
if(in_array($type, $extensions)){
$output[] = html_writer::link($qa->get_response_file_url($file),
'<img src="'.$qa->get_response_file_url($file).'/>');
}
$output[] = html_writer::tag('p', html_writer::link($qa->get_response_file_url($file),
$this->output->pix_icon(file_file_icon($file), get_mimetype_description($file),
'moodle', array('class' => 'icon')) . ' ' . s($file->get_filename())));
}
return implode($output);
}
Result
