I'm trying to customize the quick create view to add a default value of a field in Sugar Community Edition 6.5.24
Similar code works fine for ViewEdit, but it seems never called in subpanels.
Current file is
custom/modules/Opportunities/views/view.quickcreate.php
Unfortunately the constructor is not invoked.
Any help very appreciated.
<?php
require_once('include/MVC/View/views/view.quickcreate.php');
class OpportunitiesViewQuickcreate extends ViewQuickcreate {
function OpportunitiesViewQuickcreate(){
parent::ViewQuickcreate();
}
function preDisplay() {
parent::preDisplay();
$_REQUEST['custom_field_c'] = "a value for this field";
}
}
After tens of trying, I've found solution.
The right way is to extend SubpanelQuickCreate in the file custom/modules/Opportunities/views/view.subpanelquickcreate
require_once('include/EditView/SubpanelQuickCreate.php');
class OpportunitiesSubpanelQuickcreate extends SubpanelQuickCreate {
function OpportunitiesSubpanelQuickcreate() {
$_REQUEST['custom_field_c'] = "a value for this field";
parent::SubpanelQuickCreate("Opportunities");
}
}
Going from memory, so I may be wrong, but try adding $this->useForSubpanel = true; in your constructor.

I have a question about Codeigniter: Is there any way to check function exists In the controller file and then route to the function path or else route it to a specific url?
I don't know what kind of Dashboard mean in your question.
I just answer how to check function exist or not in controller and route to that function.
In some case, you may need to add a route rule in config/routes.php.
$route['/programme/(.*)$'] = 'programme/programmes/$2';
Use method_exists() to check if function exist.
class Programme extends CI_Controller {
public function programmes($sub_part = NULL) {
if (!empty($sub_part) and method_exists($this, 'programmes_'. $sub_part)) {
return $this->{'programmes_'. $sub_part}(array_slice(func_get_args(), 1));
}
die('bar')
}
private function programmes_foo() {
die('foo')
}
}
When a visitor go to https://www.foobar.com/programme/foo (foo is something affect which function to call), your website should able to show foo. If the function is not exist, it show bar.
You can use
$route['product/(:any)'] = 'yourcontroller/your_function';
Source : https://codeigniter.com/userguide3/general/routing.html
i think you can change your route into this
$route[‘produk/(:num)/(:any)’] = ‘HomeControl/detail_produk/$1/$2’;
result from that route it's like this
http://www.localhost.com/produk/1/nama-produk-1
or maybe you can read the documentation CI 3 in this link or you can read my reference this link
i hope i can help you, thanks.
I am trying to know which class has called a specific function. I've been looking through the docs for this, but without success. I already know how to get the name of a class, but that is something different of what I'm looking for. I found already something related for java but for dart I haven't. Maybe I'm missing something.
Let's say for example that I have a print function like so:
class A {
void printSomethingAndTellWhereYouDidIt() {
// Here I would also include the class where this function is
// being called. For instance:
print('you called the function at: ...');
//This dot-dot-dot is where maybe should go what I'm looking for.
}
}
class B {
A a = A();
void test() {
a.printSomethingAndTellWhereYouDidIt();
}
}
The output should be something like:
you called the function at: B
Please let me know if there are ways to achieve this. The idea behind is to then use this with a logger, for instance the logging package. Thank you in advance.
You can use StackTrace.current to obtain a stack trace at any time, which is the object that's printed when an exception occurs. This contains the line numbers of the chain of invocations leading up to the call, which should provide the information you need.
class A {
void printSomethingAndTellWhereYouDidIt() {
print(StackTrace.current);
}
}
class B {
A a = A();
void test() {
a.printSomethingAndTellWhereYouDidIt();
}
}
If you are doing this for debugging purposes, you can also set a breakpoint in printSomethingAndTellWhereYouDidIt to check where it was called from.
I am confused by how dart handles its class variables.
Consider the below snippet.
double income = 0.0;
printer() {
print(this.income);
print(income);
}
}
void main() {
Testing testing = Testing();
testing.printer();
}
Can someone enlighten me please.
Actually both prints 0. This is to refer to the class variable, if there is a name conflict.
Use this only when there is a name conflict. Otherwise, Dart style omits the this.
I'm sorry if this sounds like an extremely foolish question but it's really been bugging me.
What is the "this." that I see? Whenever I see the documentation in flutter I see it used in things like the following in the documentation:
this.initialRoute,
this.onGenerateRoute,
this.onGenerateInitialRoutes,
this.onUnknownRoute,
this.navigatorObservers
I'll be more than happy to also read up any links or documentation regarding it.
The 'this' keyword refers to the current instance.
You only need to use this when there is a name conflict. Otherwise, Dart style omits the this.
class Car {
String engine;
void newEngine({String engine}) {
if (engine!= null) {
this.engine= engine;
}
}
}
So you can be consistent with the name of your parameters, either in the constructor or in some function in the class.
class Car {
String engine;
void updateEngine({String someWeirdName}) {
engine = someWeirdName;
}
}
If you don't have a name conflict, you don't need to use this.
In other languages like Python and Swift, the word 'self' will do the same thing as 'this'.
Basically, this keyword is used to denotes the current instance. Check out the below example.
void main() {
Person mike = Person(21);
print(mike.height);
}
class Person {
double height;
Person(double height) {
height = height;
}
}
When we run this dart code, it outputs null as the height. Because we have used height = height inside the Person constructor, but the code doesn't know which height is the class property.
Therefore, we can use this keyword to denotes the current instance and it will help the code to understand which height belongs to the class. So, we can use it as below and we will get the correct output.
void main() {
Person mike = Person(21);
print(mike.height);
}
class Person {
double height;
Person(double height) {
this.height = height;
}
}
Use of this keyword
The this keyword is used to point the current class object.
It can be used to refer to the present class variables.
We can instantiate or invoke the current class constructor using this keyword.
We can pass this keyword as a parameter in the constructor call.
We can pass this keyword as a parameter in the method call.
It removes the ambiguity or naming conflict in the constructor or method of our instance/object.
It can be used to return the current class instance.
I'm trying to add some functionality from a plugin I have made into a Wordpress theme but I am having little joy. The documentation doesn't really help me solve the problem so perhaps someone here can help.
I have a plugin in Wordpress that is activated and working fine. The class for this plugin has a function called generateHtml which I would like to access from a Wordpress Theme. But whatever I try, I cannot seem to access my plugin's code.
Can either give me a summary of what I need to do to get a theme accessing code from a plugin and/or point out there I am going wrong in my code:
Plugin:
<?php
/** Usual comments here **/
if (!class_exists("ImageRotator")) {
class ImageRotator {
private $uploadPath = '';
private $pluginPath = '';
private $options;
function __construct() {
$this->uploadPath = dirname(__file__).'\\uploads\\';
// add_shortcode('imagerotator', array(&$this, 'generateHtml'));
}
// Various functions for plugin
function generateHtml() {
echo '<p>Hello World</p>';
}
}
}
/**
* Create instance of image rotator
*/
$imageRotator = new ImageRotator();
/**
* Create actions & filters for Wordpress
*/
if (isset($imageRotator)) {
// Actions
add_action('admin_menu', array(&$imageRotator, 'createMenu'));
add_action('admin_init', array(&$imageRotator, 'registerSettings'));
add_action('imagerotator_show', array(&$imageRotator, 'generateHtml'));
}
Portion from theme header page:
<?php if (isset($imageRotator)) {
$imageRotator->generateHtml();
} else if (isset($ImageRotator)) {
print_r($ImageRotator);
} else {
echo '<p>Nope!</p>';
}
if (function_exists("imagerotator_show")) {
echo 'Function found';
} else {
echo 'Function NOT found';
}
?>
Currently all I ever see is "Nope" and "Function NOT found". Thanks for any input.
Lee,
For starters, "imagerotator_show" is not a function; it's the name of a type of action. When you use the add_action() function, Wordpress just adds your method to the list of functions/methods to call when a particular action is triggered. Thus your second test will always respond with 'Function NOT found'.
The most likely cause of the first problem is failing to declare the method you want to call as a public method. You're also making the code harder than it needs to be.
The best practice I've seen for declaring methods and registering hooks from a class looks something like this:
if ( ! class_exists( 'Foo' ) ):
class Foo {
function __construct() {
add_action( 'hook_name', array( &$this, 'my_hook_implementation' ) );
}
function my_hook_implementation() {
// does something
}
public function my_special_method() {
// does something else
}
}
if ( class_exists( 'Foo' ) ):
$MyFoo = new Foo();
This allows your class to keep all of its implementation details private. When you need to call my_special_method(), you do it as follows:
$MyFoo->my_special_method();
#andrew since I can't comment I thought I would answer your ancillary question. See:
http://net.tutsplus.com/tutorials/wordpress/create-wordpress-plugins-with-oop-techniques/
Where it is explained that when defining a callback function from an object you have to use the array function. It's basically saying get the function 'my_hook_implementation' from the object $this and use it as the callback parameter to the add action hook. It is because you defined the function within the scope of the object and you have to define the scope in order for PHP to know what function you are talking about. The scope being the object referred to by the variable $this.
You just need to use do_action() function, inside your theme.
If you want the function generateHtml to appears inside your header.php you just need to open the header.php file and paste <?php do_action('imagerotator_show'); ?> where you want and then your function will be called there.
