I am creating a new Joomla Component. I am able to create custom fields for the component backend forms - but I am not able to create Dynamic Custom Fields.
What I would like to do is have a field that is dynamical populated based on the value of a previous field. The easiest way to explain this is the simple country,state,city breakdown.
Field 1 = Country
Field 2 = State (Based on what the user selected as as Country in Field 1)
Field 3 = City (Based on what the user selected as State in Field 2)
The fields would of course need to be refreshed, reset as the user picks a different country etc.
The data to populate the fields would also all need to come from a database based on the previous fields value.
I am guessing this needs to be done via ajax or javascript or something? But wondering if there is an official way? Especially since there are database calls involved.
Please let me know if there is anything I can explain better..

I ended up just creating text fields but then validating the input to make sure the values added are correct.

In Dynamics CRM 2016 (on-prem), I've custom child entity Partiesthat have a look of type order. Currently it is working properly and it is showing order name but I want it to show Order ID.
I tried to resolve by creating my own view, adding order id field only and making it default view for the look up but it don't meet my requirements.
This is controlled by the lookup view for Orders. The first three fields in the lookup view are shown when selecting records from the lookup field.
You cannot change the position of (or remove) the Name field from the lookup view. That still leaves you with two additional fields to be shown, one of which could be the Order ID.
I know no supported ways around this (except creating a workflow to copy the Order ID to the Name field and adding a custom name field instead, if you really insist).
Changing what appears on the form after you make a selection in a lookup field is not possible, unfortunately. The primary attribute is always what gets displayed after a user specifies a lookup value (which, for the Order entity, is the Name attribute). As Henrik's answer mentions, people commonly get around this by copying the value they want to see into the primary attribute using a workflow or a plugin.
In CRM Online on a customer form is there anyway that you can check if the Associated View for Assets is blank? And if its blank change a field value based on it.
Using JavaScript, 2 ways:
The associated grid is showing records related to your primary record. You can perform the same query the grid is doing using REST which will tell you if there are any records. You can then count the records, and change the field value as required. This approach is better if there are records in the database but which aren't shown in the view for some reason, e.g. view filters.
Access the Grid objects data using getRows(). As above you can then count the records, and change the field value as required. The downside of this is I believe those methods only give you access to the records shown on the form (and not any hidden by filters but still in the database) - but I don't think that that will be a problem here.
Worth bearing in mind that this approach only works client side, e.g. someone has to be actually looking at the form.
If you need to cover the a non-client side approach, e.g. workflows creating records, then you should probably look at plugin development so the changes can be performed server side.
As a side if you just want a simple count shown on form you then you should probably look at Calculated Fields and in particular Rollup fields. You might also be able to run further client side JavaScript from the count.
We have a requirement to pre-populate the Contact Form with user information on load if the user is a logged in user. So that, user need not fill his information using the webform.
Is there any way to do this using webforms for marketers?
Data is coming from a service api in json format. Need to figure out a way to bind it to fields either in server side or in client side.
Sitecore Version 7.1 140117 WFFM Version "Web Forms for Marketers
2.4.0 rev. 140117"
Have a look at Sitecore - Webforms For Marketers Form - Use ReadQueryString Option. Basically, there is a checkbox, ReadQueryString, in presentation details that gives you the option to fill in the default values from the query string. If checked, you use the item names of the fields (not the display name or title) as keys and the values you want to set the fields to as the values in key-value pair in the querystring.
Create a new rule based on use default value from user profile [fieldname] field and amend it to pick up the value from your service API.
This will be your best way and simplest option in my opinion.
I use this same approach prepopulating ucommerce data from its API.
Create custom field and then you can pre-populate values as per your need.
Like if you want to populate any value in Single line text field the create custom field for this and then reflect forms dll and copy code then update code as per your need.

I followed this tutorial on how to build a component for joomla 2.5, but now I am stuck.
What I want to do:
Besided thoses field defined in admin\models\forms\.xml I want to dynamically add form fields. The field list should be read from database.
I have a:
main table #__tours(id, title),
field list table #__tourfields(id,lable,description,position)
field value table #__tourfieldvalues(tourid,fieldid,fieldvalue)
#__tourfields contains a list of additional fields, that the user may want to specify for each entry in #__tours. #__tourfieldvalues would contain the values for the additional fields.
So now I need to figure out how to add input boxes to the edit form for each row in #__tourfields, read the values in #__tourfieldvalues for the currently to display entry of #__tours.
How can I do this?
This is very complex question. Subject to small book :)
In general you have to create class for every field type and initiate this class for every field in #__tourfields. This class have to extend JFormField and have getInput() method overridden.
Then in cycle you fetch your fields.
Something like this. But I believe you have to have more specific question. This one sounds like "How to create CMS like Joomla from scratch?"
I have a MS CRM 4 form where when certain fields are changed, I need those fields to be written to an excel sheet.
So, I edited the form field onchange event to call crmform.save() which triggers a plugin to run that writes the field value to a named range (1 cell) of an excel sheet.
However, I don't know which field caused the save. Is there a way to get that information? (Not all fields on the form need to go to the excel sheet)
If I use this: DynamicEntity target = (DynamicEntity)Context.InputParameters[ParameterName.Target];
I can look at specific fields, but I have no way of knowing which ones changed.
Any suggestions?
It's my experience that only the changed fields will have value (in the DynamicEntity) when you update an entity. So let's say you have an entity with a FirstName and Lastname. If you only change the LastName and save. The LastName will have a value however FirstName with be null (unless you have som javascript code that forces the FirstName to be submitted).
If your plugin is triggered on the Pre-Event of the Update on your entity, you should be able to compare the IPluginExecutionContext.PreEntityImages to your DynamicEntity that you've fetched from the Target.
Or if your plugin is triggered on the Post-Event of the Update, you should be able to compare the IPluginExecutionContext.PreEntityImages with IPluginExecutionContext.PostEntityImages.
Looks like you are already going a different way, but another suggestion is to create a hidden field - "FieldThatChanged." In your field on-change javascript, set that field to the name of the field that changed, then access that in your plugin.
Yep, totally changed the way I approached this. I'm using jquery in an iframe to pass all the exact fields (name/value pairs) I want to a method of an ASPX file running in the ISV folder that takes the neccesary action. Thanks for the suggestions all!
I recommend using the Pre and Post Images as suggested by #Forgotten Semicolon. And in addition set the Filtering Attributes so the Plugin is triggered only on the change of the fields you care about.
