I have a simple feedback form in a Kentico CMS site.
There are two inputs and a submit button. One of the inputs is a yes/no radio button selection and the other is a text area input. (please see screenshot).
I want the user to be able to submit the form only when at least one of the following 3 criteria are met:
'Was this page helpful?' was answered.
The text area value is not blank and the value does not equal the default text value which is 'How can we improve this page? Providing feedback helps us to improve this information'
Or, both criteria in 1 and 2 are met.
Basically, I want them to answer at least one of the inputs.
Is this type of validation possible using Kentico forms/online form web part?
Screenshot of form (may be of use):
I contacted Kentico about this functionality and their response is below:
Regrettably, this type of validation is not provided. Kentico CMS
perform validation for each built-in control separately.
In general, you have two options. The first one is to implement the
OnBeforeValidate or OnAfterValidate events which give you the ability
to perform a custom validation if necessary. You can access each field
as follows:
string answerText =
ValidationHelper.GetString(viewBiz.BasicForm.Data.GetValue("answerText"),
"");
If the validation fails, you need to set the StopProcessing of the
BizForm control to true:
viewBiz.StopProcessing = true;
More information about customization possibilities related to BizForm
can be found here:
http://devnet.kentico.com/docs/devguide/index.html?api_bizforms_customization_possibilities.htm
Another way would be creating a custom form control just as it is
described in the documentation:
http://devnet.kentico.com/docs/devguide/developing_form_controls.htm
The form control would allow users to specify both fields and
therefore you can peform the custom validation (IsValid method)
according to your requirements.
To set a field other than the field for which the for control is used,
you need to implement the GetOtherValues method.
Then, just disable the other field so that it is not displayed on the
form twice.

I want to make two sperate check box groupe. Lets say
Front end courses
-Bootstrap
-React Js
-Angular js
Back end courses
-C#
-Node
-PHP
on submitting form I want to make sure at least one course is selected by the user. Lets say a student selects ReactJs.
I have tried below code but it makes one option mandatory for all checkbox groups
[Checkbox* checkbox-11 ",Bootstrap" "React Js" "Angular JS"]
[Checkbox* checkbox-12 ",C#" "Node" "PHP"]
How can I make at least one option selected mandatory from any of the checkbox groups
field validation takes place post form submission. To solve this problem you need to make neither field mandatory, and then do a custom validation on the server side. CF7 plugin allows you to add custom validation to individual field but does not allow you to validate a field wrt to the value of other fields in the form.
To do this you need an extension such as the Smart Grid-layout plugin which has a validation hook that gives you access to the entire form's submitted data and therefore cross-validate your fields,
add_filter('cf7sg_validate_submission', 'cross_validate_submission',10,3);
function cross_validate_submission($validation, $submission, $form_key){
if(empty($submission['fe-courses']) && empty($submission['be-courses'])){
$validation['fe-courses']='You need to select at least 1 course!';
}
return $validation;
}
I want to create a validator for an angular2 form that involves several controls. So far, all I have found is how to create validators for controls inside a form, in an isolated way, like this:
this.myControl = new FormControl('',Validators.Required);
but I didn't find any example of a validator that involves the state of several controls at the same time.
To explain my case, here is a simple example.
In this example, what I want is:
IF the checkbox is selected, I want the two input boxes to be NOT REQUIRED.
IF the checbox is NOT selected, I want the two input boxes to be REQUIRED.
I could to this programmatically, but I wanted to know if there is an elegant solution that involves validators at a form level, not only at FormControl level.
I have a custom page type, and the editor will have the option to enter the following
Image (from media library)
Video (from media library)
YouTube video ID
The field names are as follows
SlideImage
SlideVideo
YouTubeVideoID
So, if an editor ads a SlideImage, SlideVideo and YouTubeVideoID should not be usable. Same for SlideVideo and YouTubeVideoID.
Within the Visibility Condition fields, i'm going to assume a macro is needed for this. My logic is:
This field visible if Field A or B have data.
A possible approach can be to add an additional field, which determines the field that should be used.
Create a text field (let's say, SlideType) and use a radio button form control with your options:
image;Image
video;Video
youtube;YouTube
Tick the "Has depending fields" checkbox for this field, and tick the "Depends on another field" checkbox for the SlideImage, SlideVideo and YouTubeVideoID fields.
Your visibility conditions would then be simplified, instead of checking the values of multiple fields.
For example, the visibility condition for the SlideVideo field would be:
SlideType == "video"
This has a few benefits:
Easy to add new fields and configure the visibility conditions
Easy to check what needs to be rendered in the front-end - in your repeaters and other webparts, you can simply have conditional statements on the SlideType field to determine which field to use
Intuitive for the end user - the interface makes it clear which field is being used
Add this to Visibility condition in Page type field edit:
Fields.SlideImage.Value == String.Empty
Do not forget to set proper Has depending fields and Depends on another field properties depending on your needs. You can learn more about these properties here.
Let's say the column name on which this value of your depending field is "FirstName", so you can write in the dependent field -> Visibility Condition as
FirstName.value != ""
or
FirstName.value
You can twist the conditions for as many conditions as possible and can club more than one condition too.
I am also sharing links with you having a lot of examples from Kentico support

I'm looling for a way to change the text above the form in a same manner as the fields use the progressive profiling.
At the bottom of this page " http://www.pardot.com/faqs/forms/setting-progressive-profiling/ " it says:
If you would like to have multiple progressive questions per “phase” of the form then use the same logic as designated above for all fields in that “phase”.
But no further explanation or example is given ( if this even applies to the 'above form' text )
The text above (or below) the form can not be changed by actions in the form. Your best bet to change this text above the form is to use dynamic content, which only works on populated fields for known prospects when the page is loaded. Dynamic content is useless for anonymous visitors..
Multiple questions per 'phase' allows you to have several fields appear after a single selection. For example, you ask for 'delivery' preferences - email, download, mail - and the user selects 'mail' you can have a full contact field set appear.
In Drupal 7, is there a way to change the standard edit form for a content type based on a certain content?
For example:
I have a content type with a checkbox...once it it checked and the form is saved, I do not want this checkbox to be visible anymore...therefore based on the checkboxes value in the Database I want to hide form fields when showing the form.
I am building a small specific project site, where a company wants to add projects, and their customers are supposed to follow certain steps (upload some content, provide information etc.), and also should be able to check off certain requirements, and once these are checked off, they should not be visible/editable to them.
Also the displayed form fields should depend on an user's role, and then FURTHER be limited depending on the content's database entries.
Is there a module, which could achieve this behaviour? "rules" and "field/permissions" come close to what I need, but are not sufficient. Or did I just miss the option to change a form field's accessibility based on conditions?
What I need is some place to define a logic like "IF (VALUEOF(CHECKBOX_1) == TRUE) THEN DO_NOT_SHOW(CHECKBOX_1)"
hook_form_alter is the way to do this, as explained by Mihaela, but what options do you have inside that function?
If you want just to disable field (it will be visible, but user can't change it) you can do it like this:
$form['field_myfield']['#disabled'] = TRUE;
And if you want it to be hidden, but to keep value it has before editing the way to do that is:
$form['field_myfield']['#access'] = FALSE;
I.e. hiding it (somewhere I saw someone suggesting that):
hide($form['field_myfield']);
really hides the field, but after that, when form is saved this field has empty value, validation fails, etc, so that's not a good way to do this. Hiding makes sense only if you want to print separately that field later, at some other place.
function your_module_form_alter(&$form, &$form_state, $form_id){
switch($form_id) {
case 'nameOfTheNode_node_form':
//your code here. check the value from from_state.
break;
}
}
In this case, I use module Conditional Fields https://www.drupal.org/project/conditional_fields
For example: If my Dependees field has a value, Dependent field can be visible/invisible, enabled/disabled, required/optional, checked/unchecked
