I have created a custom page on which all available courses are displayed. I have also uploaded the image for the course and now want to show the name of the course along with the image. I am able to get the names of courses from the database but how to get the image.
Try something like this
// Create a course_in_list object to use the get_course_overviewfiles() method.
require_once($CFG->libdir . '/coursecatlib.php');
$course = new course_in_list($courseid);
$outputimage = '';
foreach ($course->get_course_overviewfiles() as $file) {
if ($file->is_valid_image()) {
$imagepath = '/' . $file->get_contextid() .
'/' . $file->get_component() .
'/' . $file->get_filearea() .
$file->get_filepath() .
$file->get_filename();
$imageurl = file_encode_url($CFG->wwwroot . '/pluginfile.php', $imagepath,
false);
$outputimage = html_writer::tag('div',
html_writer::empty_tag('img', array('src' => $imageurl)),
array('class' => 'courseimage'));
// Use the first image found.
break;
}
}
echo $outputimage;
You may get course image directly from 'overviewfiles' files area.
function get_course_image()
{
global $COURSE;
$url = '';
require_once( $CFG->libdir . '/filelib.php' );
$context = context_course::instance( $COURSE->id );
$fs = get_file_storage();
$files = $fs->get_area_files( $context->id, 'course', 'overviewfiles', 0 );
foreach ( $files as $f )
{
if ( $f->is_valid_image() )
{
$url = moodle_url::make_pluginfile_url( $f->get_contextid(), $f->get_component(), $f->get_filearea(), null, $f->get_filepath(), $f->get_filename(), false );
}
}
return $url;
}

Please check this code for the custom block to be placed in the dashboard. We want to display an HTML table for the records. But it does not add up to the custom block, rather it appears on the top page.
enter image description here
class block_scorecard extends block_base {
function init() {
$this->title = get_string('pluginname', 'block_scorecard');
}
function get_content() {
global $DB;
if ($this->content !== NULL) {
return $this->content;
}
$content = '';
$courses = $DB->get_records('scorm_scoes_track', ['element' => 'cmi.core.total_time']);
$table=new html_table();
$table->head=array('No of attempts','Time modified','status');
foreach ($courses as $course) {
$attempt=$course->attempt;
$timemodified=userdate($course->timemodified, get_string('strftimerecentfull'));
$status=$course->value;
$table->data[]=array($attempt, $timemodified, $status);
}
echo html_writer::table($table);
$this->content = new stdClass;
$this->content->text = $content;
}}
echo html_writer::table($table);
Should be
$content .= html_writer::table($table);
My first Sphinx app almost works!
I successfully save path,title,content as attributes in index!
But I decided go to SphinxQL PDO from AP:
I found snippets() example thanks to barryhunter again but don't see how use it.
This is my working code, except snippets():
$conn = new PDO('mysql:host=ununtu;port=9306;charset=utf8', '', '');
if(isset($_GET['query']) and strlen($_GET['query']) > 1)
{
$query = $_GET['query'];
$sql= "SELECT * FROM `test1` WHERE MATCH('$query')";
foreach ($conn->query($sql) as $info) {
//snippet. don't works
$docs = array();
foreach () {
$docs[] = "'".mysql_real_escape_string(strip_tags($info['content']))."'";
}
$result = mysql_query("CALL SNIPPETS((".implode(',',$docs)."),'test1','" . mysql_real_escape_string($query) . "')",$conn);
$reply = array();
while ($row = mysql_fetch_array($result,MYSQL_ASSOC)) {
$reply[] = $row['snippet'];
}
// path, title out. works
$path = rawurlencode($info["path"]); $title = $info["title"];
$output = '<a href=' . $path . '>' . $title . '</a>'; $output = str_replace('%2F', '/', $output);
print( $output . "<br><br>");
}
}
I have got such structure from Sphinx index:
Array
(
[0] => Array
(
[id] => 244
[path] => DOC7000/zdorovie1.doc
[title] => zdorovie1.doc
[content] => Stuff content
I little bit confused with array of docs.
Also I don't see advice: "So its should be MUCH more efficient, to compile the documents and call buildExcepts just once.
But even more interesting, is as you sourcing the the text from a sphinx attribute, can use the SNIPPETS() sphinx function (in setSelect()!) in the main query. SO you dont have to receive the full text, just to send back to sphinx. ie sphinx will fetch the text from attribute internally. even more efficient!
"
Tell me please how I should change code for calling snippet() once for docs array, but output path (link), title for every doc.
Well because your data comes from sphinx, you can just use the SNIPPET() function (not CALL SNIPPETS()!)
$query = $conn->quote($_GET['query']);
$sql= "SELECT *,SNIPPET(content,$query) AS `snippet` FROM `test1` WHERE MATCH($query)";
foreach ($conn->query($sql) as $info) {
$path = rawurlencode($info["path"]); $title = $info["title"];
$output = '<a href=' . $path . '>' . $title . '</a>'; $output = str_replace('%2F', '/', $output);
print("$output<br>{$info['snippet']}<br><br>");
}
the highlighted text is right there in the main query, dont need to mess around with bundling the data back up to send to sphinx.
Also shows you should be escaping the raw query from user.
(the example you found does that, because the full text comes fom MySQL - not sphinx - so it has no option but to mess around sending data back and forth!)
Just for completeness, if REALLY want to use CALL SNIPPETS() would be something like
<?php
$query =$conn->quote($_GET['query']);
//make query request
$sql= "SELECT * FROM `test1` WHERE MATCH($query)";
$result = $conn->query($sql);
$rows = $result->fetchAll(PDO::FETCH_ASSOC);
//build list of docs to send
$docs = array();
foreach ($rows as $info) {
$docs[] = $conn->quote(strip_tags($info['content']));
}
//make snippet reqest
$sql = "CALL SNIPPETS((".implode(',',$docs)."),'test1',$query)";
//decode reply
$reply = array();
foreach ($conn->query($sql) as $row) {
$reply[] = $row['snippet'];
}
//output results using $rows, and cross referencing with $reply
foreach ($rows as $idx => $info) {
// path, title out. works
$path = rawurlencode($info["path"]); $title = $info["title"];
$output = '<a href=' . $path . '>' . $title . '</a>'; $output = str_replace('%2F', '/', $output);
$snippet = $reply[$idx];
print("$output<br>$snippet<br><br>");
}
Shows putting the rows into an array, because need to lopp though the data TWICE. Once to 'bundle' up the docs array to send. Then again to acully display rules, when have $rows AND $reply both available.
I am creating a custom theme for OpenCart 2.3 and I need to show some additional information in page header (header.tpl). So I added some variable to catalog/controller/common/header.php:
$data['some_var'] = 'some_value';
And then I am trying to use this data in the header.tpl:
<?php echo $this->data['some_var']; ?>
But I am always getting this error:
Notice: Undefined index: some_var in /var/www/store_com/public_html/catalog/view/theme/mystore/template/common/header.tpl on line 133
If I try to use this code:
<?php echo $some_var; ?>
Then I am getting another error:
Notice: Undefined variable: some_var in /var/www/store_com/public_html/catalog/view/theme/mystore/template/common/header.tpl on line 133
And even when I do echo print_r($this->data) in header.tpl I don't even see this variable in $data array.
What am I doing wrong? Please help.
EDIT
Here is the full code of my header.php controller file. I added my custom variable at the very end of the file.

I need to see your controller to get the full picture and then i will give you the full answer, but take a look on your controller and make sure that you bind your data like the sample below:
if (file_exists(DIR_TEMPLATE . $this->config->get('config_template') . '/template/common/header.tpl')) {
return $this->load->view($this->config->get('config_template') . '/template/common/header.tpl', $data);
} else {
return $this->load->view('default/template/common/header.tpl', $data);
}
Thanks
I finally found the solution of my problem, but I am not sure if it is the right way to do this. I found that I need to make changes in system/storage/modification/catalog/controller/common/header.php. It seems like after installing some extension via Vqmod the controller file have been copied to this folder. If I add my variables there then I can access them without any issues.
Gravity forms offers a way to attach files from the file uploader (See code below), but how would I change this code to simply attach my own PDF file from either a hidden field value or simply paste the pdf file within this code? I tried a few things but it didn't work. Any help would be appreciated!
add_filter( 'gform_notification', 'change_user_notification_attachments', 10, 3 );
function change_user_notification_attachments( $notification, $form, $entry ) {
//There is no concept of user notifications anymore, so we will need to target notifications based on other criteria, such as name
if ( $notification['name'] == 'User Notification' ) {
$fileupload_fields = GFCommon::get_fields_by_type( $form, array( 'fileupload' ) );
if(!is_array($fileupload_fields))
return $notification;
$attachments = array();
$upload_root = RGFormsModel::get_upload_root();
foreach( $fileupload_fields as $field ) {
$url = $entry[ $field['id'] ];
$attachment = preg_replace( '|^(.*?)/gravity_forms/|', $upload_root, $url );
if ( $attachment ) {
$attachments[] = $attachment;
}
}
$notification['attachments'] = $attachments;
}
return $notification;
}
Based on that code, something like this should work. Replace the $url value with the URL to your PDF.
add_filter( 'gform_notification', 'change_user_notification_attachments', 10, 3 );
function change_user_notification_attachments( $notification, $form, $entry ) {
if ( $notification['name'] == 'User Notification' ) {
$url = 'http://yoursite.com/path/to/file.pdf';
$notification['attachments'][] = $url;
}
return $notification;
}
I have am having trouble setting the basic values of a zend form element submit button (Zendframework1). I basically want to set a unique id number in it and then retrieve this number once the button has been submitted.
Below is my code. you will nots that I tried to use the setValue() method but this did not work.
$new = new Zend_Form_Element_Submit('new');
$new
->setDecorators($this->_buttonDecorators)
->setValue($tieredPrice->sample_id)
->setLabel('New');
$this->addElement($new);
I would also appreciate any advice on what I use to receive the values. i.e what method I will call to retrieve the values?
The label is used as the value on submit buttons, and this is what is submitted. There isn't a way to have another value submitted as part of the button as well - you'd either need to change the submit name or value (= label).
What you probably want to do instead is add a hidden field to the form and give that your numeric value instead.
It's a little bit tricky but not impossible :
You need to implement your own view helper and use it with your element.
At first, you must add a custom view helper path :
How to add a view helper directory (zend framework)
Implement your helper :
class View_Helper_CustomSubmit extends Zend_View_Helper_FormSubmit
{
public function customSubmit($name, $value = null, $attribs = null)
{
if( array_key_exists( 'value', $attribs ) ) {
$value = $attribs['value'];
unset( $attribs['value'] );
}
$info = $this->_getInfo($name, $value, $attribs);
extract($info); // name, value, attribs, options, listsep, disable, id
// check if disabled
$disabled = '';
if ($disable) {
$disabled = ' disabled="disabled"';
}
if ($id) {
$id = ' id="' . $this->view->escape($id) . '"';
}
// XHTML or HTML end tag?
$endTag = ' />';
if (($this->view instanceof Zend_View_Abstract) && !$this->view->doctype()->isXhtml()) {
$endTag= '>';
}
// Render the button.
$xhtml = '<input type="submit"'
. ' name="' . $this->view->escape($name) . '"'
. $id
. ' value="' . $this->view->escape( $value ) . '"'
. $disabled
. $this->_htmlAttribs($attribs)
. $endTag;
return $xhtml;
}
}
So, you assign the helper to the element :
$submit = $form->createElement( 'submit', 'submitElementName' );
$submit->setAttrib( 'value', 'my value' );
$submit->helper = 'customSubmit';
$form->addELement( $submit );
This way, you can retrieve the value of the submitted form :
$form->getValue( 'submitElementName' );
