Im new for PHP and Moodle..., I want set "Max enrolled users" in the page "Add a new course".
In this moment i did this code in archive(moodle\course\edit_form.php):
$mform->addElement('text', 'customint3', get_string('maxenrolled', 'enrol_self'));
$mform->addHelpButton('customint3', 'maxenrolled', 'enrol_self');
$mform->setType('customint3', PARAM_INT);
but i know miss something for use Self Enrolment in this page... like active the table "enrol_self"...
For use "Self Enrolment" , first need to get "CourseID". Because in the page of "Self Enrolment" need a foreign key for updating the format of a course.
So... how can I do in the code "edit_form.php" for creating a course and updating Enrolment Self(maxenrolled) immediately after click the button?? Have function of moodle for easy edit it??
Need your advice please!! And thanks!!
You can set the default for max enrolled in the plugin settings. Go to site admin -> plugins -> enrolment -> self enrolment
or go directly to yoursite.com/admin/settings.php?section=enrolsettingsself
If you want to use a different value each time, then in /enrol/self/edit.php look for this code (this is the code in Moodle 2.5 it might be slightly different in other versions):
} else {
require_capability('moodle/course:enrolconfig', $context);
// No instance yet, we have to add new instance.
navigation_node::override_active_url(new moodle_url('/enrol/instances.php', array('id'=>$course->id)));
$instance = (object)$plugin->get_instance_defaults();
$instance->id = null;
$instance->courseid = $course->id;
$instance->status = ENROL_INSTANCE_ENABLED; // Do not use default for automatically created instances here.
}
and insert this line
$instance->courseid = $course->id;
$instance->customint3 = $yourdefault; // Your new default.
$instance->status = ENROL_INSTANCE_ENABLED;

I have a problem with my Laravel crud application for Registrations.
There are these tables: Registration, ExtraRegistration (with a registration_id, extra_id and extraoptions_id),
Extra and ExtraOptions (with the Extra_id).
In the RegistrationController when i add a Registration it makes a new record in the ExtraRegistration with the extraoptions_id and the extra_id. the extra_id is the name of the option and the extraoptions_id is the id of the option you selected.
But now, when you click on edit a record, it shows all the information. the problem is that when you change the extraoption, it makes another record, and not change the select.
And when you have edited something and you look at it again, it still shows the option before you edited it.
RegistrationController
$options = Extra::where("exa_form_id", $distance->asd_form_id)->get();
foreach($options as $option){
$input_name = "option_" . $option->exa_id;
$input_option = $request->$input_name;
if(!is_null($input_option)){
$input_name_extra = "extraoptions_" . $option->exa_id;
$input_option_extra = $request->$input_name_extra;
$registrationextra = new ExtraRegistration();
$registrationextra->iea_registration_id = $registration->isg_id;
$registrationextra->iea_extra_id = $input_option;
$registrationextra->iea_extraoption_id = $input_option_extra;
$registrationextra->iea_price = $option->exa_price;
$registrationextra->save();
}
}
$registration->isg_options = $input_option;
$registration->isg_option_extra_id = $input_option_extra;
I want a check before it makes a new ExtraRegistration. that it only makes a new registration if the registration_id with that extra_id doesn't already exists. (Not 100% sure though).
Thanks in advance!
you make a new object of ExtraRegistration so its always make a new entry for update first get object of those id after that update
check the below link
https://laravel.com/docs/5.8/eloquent#updates
This happens because you're creating a new ExtraRegistration record:
$registrationextra = new ExtraRegistration();
If you want to update it, you need to find the related $registrationextra for your $options, and then update them (assuming you have relations set up):
$registrationextra = ExtraRegistration::where('options_id', $option->id);
$registrationextra->update([
'your_fields' => value
// etc...
]);
If you want to check if ExtraRegistration exists, and depending on that, create or update it, you can do something like this:
$registrationextra = App\ExtraRegistration::updateOrCreate(
['your_fields' => 'value'],
);
You can read more on official documentation.
I'm developing a Joomla 3.x plugin, and want to be able to change the plugin parameter set in the plugin's manifest file programmatically. I believe I need to use a JRegistry object, but I'm not sure about the syntax.
Here's the issue:
// token A is set in plugin params as defined in plugin's XML manifest
var_dump($this->params->get('token')); // prints token "A" as expected
// do some stuff to get a fresh access token, called token "B"
$tokenB = $function_to_get_fresh_token();
// set the new token
if ($tokenB) $this->params->set('token', $tokenB);
var_dump($this->params->get('apptoken')); // prints token "B" as expected
the problem is that on subsequent page reloads, the token reverts to tokenA rather than what I assumed would be the stored value of tokenB.
How do I store the tokenB value in the plugin's parameters in the database?
This is a working example of how to change plugin params from within the plugin (J! 3.4):
// Load plugin called 'plugin_name'
$table = new JTableExtension(JFactory::getDbo());
$table->load(array('element' => 'plugin_name'));
// Params can be changed like this
$this->params->set('new_param', 'new value'); // if you are doing change from a plugin
$table->set('params', $this->params->toString());
// Save the change
$table->store();
Note: If new params are added by plugin dynamically and the plugin is saved afterwards, these new params gets deleted. So one way to deal with it is to add those params as hidden fields to plugin's config XML.
This is just an outline, but something along these lines
$extensionTable = new JtableExtension();
$pluginId = $extensionTable->find('element', 'my_plugin');
$pluginRow = $extensionTable->load($pluginId);
// Do the jregistry work that is needed
// do some stuff to get a fresh access token, called token "B"
$tokenB = $function_to_get_fresh_token();
// set the new token
if ($tokenB) $this->params->set('token', $tokenB);
// more stuff
$extensionTable->save($pluginRow);
I spent a lot of time googling and reading and found no real answer to this. Oddly enough this doesn't seem to have been provided for in Joomla. So here's what I ended up doing:
1) build a function to get your plugin ID, since it will change from one installation to another
private function getPlgId(){
// stupid hack since there doesn't seem to be another way to get plugin id
$db = JFactory::getDBO();
$sql = 'SELECT `extension_id` FROM `#__extensions` WHERE `element` = "my_plugin" AND `folder` = "my_plugin_folder"'; // check the #__extensions table if you don't know your element / folder
$db->setQuery($sql);
if( !($plg = $db->loadObject()) ){
return false;
} else {
return (int) $plg->extension_id;
}
}
2) use the plugin id to load the table object:
$extension = new JTableExtension($db);
$ext_id = $this->getPlgId();
// get the existing extension data
$extension->load($ext_id);
3) when you're ready to store the value, add it to the params, then store it:
$this->params->set('myvalue', $newvalue);
$extension->bind( array('params' => $this->params->toString()) );
// check and store
if (!$extension->check()) {
$this->setError($extension->getError());
return false;
}
if (!$extension->store()) {
$this->setError($extension->getError());
return false;
}
If anyone knows a better way to do this please let me know!
I've been looking for this like everywhere now ;)
I want to add the product image to the popup, but I can't figure out how to achieve this!
I've been searching for hours and hours now and next to that tried to code this myself but it won't work.
So now I'm asking for help... if anyone has some ideas on this please let me know.
Afaik there's more people on the net that would like to see a "add to cart"-popup with some more informations given on it.
Sincerly Thomas
I just recently customised the add to cart popup on a site myself. The file you need to edit is components/com_virtuemart/controllers/cart.php (the function is called addJS if I remember correctly).
You can find the API documentation for VirtueMart here: http://docs.virtuemart.net/api-vm2/ however I wrote my own plugin to fetch the VM data.
Then you can just use standard PHP rather than getting your head round the VM API.
If you decide to do it my way you can call custom classes from your plugin and output the image like so:
$cart_image = plgMyCoolPlugin::_getImage($this->product->virtuemart_product_id);
echo '<img src='.$cart_image.'/>';
Remember you need to import your plugin type if you don't make it a system plugin:
JPluginHelper::importPlugin( 'mynewplugintype' );
Here's the function I use in my plugin:
function _getImage($id)
{
$db =& JFactory::getDBO();
$sql = " SELECT
b.`file_url`
FROM
".$db->nameQuote('#__virtuemart_product_medias')." AS a
INNER JOIN
".$db->nameQuote('#__virtuemart_medias')." AS b ON a.`virtuemart_media_id` = b.`virtuemart_media_id`
WHERE
a.".$db->nameQuote('virtuemart_product_id')." = ".$id."
AND
b.".$db->nameQuote('file_mimetype')." = 'image/jpeg'
AND
b.".$db->nameQuote('file_type')." = 'product'
AND
b.".$db->nameQuote('file_is_forSale')." = '0'";
$query = $db->setQuery($sql);
$row = $db->loadResultArray();
if($db->getErrorNum()) {
JError::raiseError( 500, $db->stderr());
}
if(empty($row)) $row[] = JURI::base().'images/defaultimage.jpg';
return $row;
}
Hope this helps :)
I have created a Link DataObject to automatically let users create a reference to a different page in the Frontend. I use two languages in the frontend, German and English. In the popup I create a dropdown to select the pages
public function getCMSFields_forPopup()
{
return new FieldSet(
new TextField('Titel'),
new TextField('URL', 'Externer Link'),
new SimpleTreeDropdownField('PageLinkID', 'Interner Link', 'SiteTree')
);
}
But I only get the German pages in the dropdown. Tried to change the admin language to English but no change. The database seems to only return the German pages...
Any clue?
Edit: I did some more digging and found out how to do this. You need to call "disable_locale_filter" before you get your SiteTree objects:
Translatable::disable_locale_filter();
Then call "enable_locale_filter" once you've retrieved them:
Translatable::enable_locale_filter();
These are other approaches which I'll leave here as I think they are still useful...
I believe you may have to do this using Translatable::get_by_locale() - I assume you only want people to be able to select a page to link to within their language??
Perhaps something like this?
public function getCMSFields_forPopup()
{
$member = Member::currentUser();
if($member && $member->Locale) {
$pagesByLocale = Translatable::get_by_locale('SiteTree', $member->Locale);
$pagesByLocale = $pagesByLocale->map('ID', 'Title', '(Select one)', true);
return new FieldSet(
new TextField('Title'),
new TextField('URL', 'Externer Link'),
new DropdownField('PageLinkID', 'Interner Link', $pagesByLocale);
);
} else {
// Handle non-member
}
}
Edit: see comments below but another option is to use the Translatable::get_current_locale() function to find all pages in the Site Tree for that locale... if the user is viewing an english page then the locale should be set to english etc...
public function getCMSFields_forPopup()
{
$pagesByLocale = Translatable::get_by_locale('SiteTree', Translatable::get_current_locale());
$pagesByLocale = $pagesByLocale->map('ID', 'Title', '(Select one)', true);
return new FieldSet(
new TextField('Title'),
new TextField('URL', 'Externer Link'),
new DropdownField('PageLinkID', 'Interner Link', $pagesByLocale);
);
}
You can also get the locale from the current page e.g.
$this->Locale; // From within the model
$this->dataRecord->Locale; // from within the controller
Director::get_current_page()->Locale; // If you're outside the context of the page altogether i.e. code inside your DataObject.
Ok, its possible to add a new attribute set in magento using something like the following:
$entitySetup = new Mage_Eav_Model_Entity_Setup;
$entitySetup->addAttributeSet('catalog_product', $setName);
But how can i base the set on an existing set like the default. This option is available in the admin section so its possible.
I did this 6 months ago, I do not have the code anymore, but I know you have to use the initFromSkeleton() method on your attribute set. You can search Magento's code for calls to this function, there are very few calls (just one perhaps). It will show you its usage.
EDIT: I remember I had the very same problem you are talking about, and I mailed about it. Here is the usage I was advised:
$attrSet = Mage::getModel('eav/entity_attribute_set');
$attrSet->setAttributeSetName('MyAttributeSet');
$attrSet->setEntityTypeId(4);//You can look into the db what '4' corresponds to, I think it is for products.
$attrSet->initFromSkeleton($attrSetId);
$attrSet->save();
The initialization is done before the save.
// create attribute set
$entityTypeId = Mage::getModel('eav/entity')
->setType('catalog_product')
->getTypeId(); // 4 - Default
$newSet = Mage::getModel('eav/entity_attribute_set');
$newSet->setEntityTypeId($entityTypeId);
$newSet->setAttributeSetName(self::ATTRIBUTE_SET_NAME);
$newSet->save();
$newSet->initFromSkeleton($entityTypeId);
$newSet->save();
This is what worked for me.
$i_duplicate_attribut_set_id = 10; // ID of Attribut-Set you want to duplicate
$object = new Mage_Catalog_Model_Product_Attribute_Set_Api();
$object->create('YOUR_ATTRIBUT_SET_NAME', $i_duplicate_attribut_set_id);

Here you can find useful information about working with attribute sets.
Here:
$entityTypeId = Mage::getModel('eav/entity')
->setType('catalog_product') // This can be any eav_entity_type code
->getTypeId();
$attrSet = Mage::getModel('eav/entity_attribute_set');
$attrSetCollection = $attrSet->getCollection();
$attrSetCollection
->addFieldToFilter('entity_type_id', array('eq' => $entityTypeId))
->addFieldToFilter('attribute_set_name', array('eq' => 'Default')); // This can be any attribute set you might want to clone
$defaultAttrSet = $attrSetCollection->getFirstItem();
$defaultAttrSetId = $defaultAttrSet->getAttributeSetId();
$attrSet->setAttributeSetName('Assinaturas'); // This is the new attribute set name
$attrSet->setEntityTypeId($entityTypeId);
$attrSet->initFromSkeleton($defaultAttrSetId);
$attrSet->save();
