I need your help. I have an Active Form in my Yii2 application and when I submit my form it shows values (no matter empty or not) of every field of the form to the GET-string so it looks like
domain.com/index?ItemSearch%5Brooms_arr%5D=&ItemSearch%5Bprice_type%5D=& ItemSearch%5Bprice_type%5D=0&ItemSearch%5Barea_from%5D=&ItemSearch%5Barea_to%5D=&... etc.
I need to have cleaner query string which will contain only non-empty params?
For example domain.com/index?rooms_arr=12&price_type=normal.
Please suggest me what is the best way to do this?
This is not the yii2 problem. It is a native html form works like this. If you really do want to exclude all not filled inputs from the query string you could filter all this params via jQuery and set them to disable state, here is the code
$('form').submit(function(e){
var emptyinputs = $(this).find('input').filter(function(){
return !$.trim(this.value).length; // get all empty fields
}).prop('disabled',true);
});

I have a simple form that's in a dialog fragment used to submitting two fields for log-in auth.
For simplicity I was hoping to not have to use data binding, but rather use some method to gather all data inside my sap.ui.layout.form.SimpleForm.
I added a name property to each input element which says in the docs it is " Defines the name of the control for the purposes of form submission."
https://openui5.hana.ondemand.com/#/api/sap.m.InputBase/controlProperties#name
However hard as I try to find there doesn't seem to be any getFormData methods.
All SO questions and guides either use data binding to a model, or hard-code references to the individual input controls with .getValue() methods.
And looking further into the form API, there doesn't seem to be a Submit event either.
Given an arbitrary form, what would be the best way to gather all submission values without hard-coded references or data-binding?
Would a method that walks though all the children elements of a form looking for all submission values work? I think it might, but there are more submission input types then just the input component.
You can get the value of the fields by directly using;
var oField = sap.ui.getCore().byId('IdOfTheFieldAtTheDialog');
var sValue = oField.getValue();
But it's always better and convenient to use data binding which keep things neat.
And If I assume that you have the id of parent form container, you can iterate over the items and get the sap.m.Input elements in it without knowing the IDs of the individual inputs, and you may check the name property of the fields if you want. Check this snippet;

I have a problem with my front end admin update page. How can I retrieve values from a SiteTree page and populate it into a custom form? Is the setValue($values) function the only way? If yes, which is the best method to get the page variable?
I am using this:
$evens = Versioned::get_by_stage('PageCalendrierEvenement', 'Stage')->byID($evenID);
I'm getting values from an ID of a draft page. After I get variables and values like that:
$field = new TextField('Titre', 'Titre');
$field->setValue($evens->Titre);
or
new TextField('Titre','Titre', $evens->Titre);
Which is the better solution?
The solution is 2 part:
Use TextField::create($constructor, $args) instead of new (optional, but not doing so is a pet hate of mine).

I have a page where I need to display testimonials, In that page document type I have a field to assign testimonials by using page selection, so It will save the GUID of selected testimonial in the database,
I have used following code to display the description of Testimonial, But is there any other way to get the document fileds by passing the GUID,
One option I can use is write a custom macro.
{% Documents["/Page-Resource/Testimonial/Testimonial"].getValue("Description") #%}
Note: I have used the text/xml type transformation
Well it's not that easy but there is one way and that is to use loops:
r = ""; foreach (i in CMSContext.Current.Documents) {if(i.NodeGUID == "a88f82be-bb76-4b82-8faf-5253209f0f75"){r = i}}; r.Description
Notes:
Use NodeGUID or DocumentGUID based on what you store in your custom field.
Replace the hardcoded guid with something like CMSContext.Current.CurrentDocument.YourDescriptionFieldWithGuid
See the documentation if you have any doubts about K# syntax
I have multiple form fields in an angular view that count down characters as the user types. However, I have a button/link that should reset all the form fields and character counts. When clicked, the form is reset but the character counts are not updated to reflect the change. I know there has to be a model connection I am missing here (I'm an angular newbie). I also know it's probably best to rest the form using $setPristine();, but I am unable to get that to work.
Here's what I've got: http://embed.plnkr.co/5SGjqPhYYIZF1qp0QAAT/preview
I'd appreciate any help I can get! Thanks!
The problem is that your reset button isn't updating the Angular model values your character count calculations rely upon.
Instead of using reset on the form element, just clear the model values:
HTML:
<a href ng-click="clearForm()">RESET</a>
Controller:
$scope.clearForm = function() {
$scope.TA3 = '';
$scope.TA4 = '';
}

I'm creating my form using the Form helper, so the action of the form is specified automatically....
this form is used for editing a post..
so, the URL has the structure: mywebsite.com/posts/edit/id
and the form's action should be automatically generated as posts/edit/id
but the problem is, in some cases, I open the HTML code and I find that the form's action is only posts/edit without the id which causes the update to fail...
I spent a lot of time to figure out what situation brings this wrong action:
i'm generating fields dynamically (using javascript & ajax) depending on the post's category..
when the value of one of the dynamically generated fields is invalid, the generated action becomes posts/edit !!
I really need help, cuz I don't know why this is happening !!!
and I don't wanna waste more time digging into the core of cakephp...
so, if any of cakephp experts has an idea about this, plz help me !!
thank you in advance !
Use the url parameter, which allows you to explicitly define a url for the form:
echo $form->create('Post', array('url' => $html->url(array('action'=>'edit', $id))));
It sounds like $id probably isn't getting set, because it should be getting passed along if it is. You need to make sure it's set to edit the record in question. Make sure your javascript is including the hidden field with the record's id in it.
Normally done like this, with the form helper: echo $this->Form->input('id');
Also, if one of the fields is invalid, the form shouldn't actually be submitting properly, if you are using cake's validation, so this is to be expected.
