Could anyone advice on the correct way to retrieve and check the value of a textfield with Zend_Test_PHPUnit_ControllerTestCase? The assert conditions are fine for css selectors, but I cannot see a way of checking that a textfield or other form element is correctly populated? any clues much appreciated!
you should validate data entry with Zend_Validate (which is part of the production code). you then would unit test that the value is retrieved correctly after it was stored in the DB.

I'm trying to implement a live search combo. It suppose to work like this:
When I enter a character into the combo field I read the current value and send it as a parameter to the store's url. In the backend the parameter is used to return any value from the database that contains it, so the store behind the combo gets filled only with those filtered values.
As I continue to enter characters into the combo, the parameter should be updated and sent again to the backend and so on, getting like this a smaller and smaller store.
I tryied to achieve this behaviour using the combo's event keypress, even keyup, but the problem is it's impossible for me to get access to the current value from the combo field.
For example, when I entered the "for" string into the combo, how can I obtain this value using the combo object? comboName.getValue() doesn't work, it returns nothing "".
I already saw the live combo example here: http://docs.sencha.com/extjs/4.2.2/#!/example/form/forum-search.html but doesnt help me at all.
So my big question is: how do i get the current value while still editing the combo's field?
Any help would be appreciated, thanks.
You should be able to use
comboName.getValue();
or
comboName.getRawValue();
Where comboName is your combo box. Are neither working- I note in your post you state getValues() which is an improper method. You may want to also check whether when you're referring to your combo box object, that the reference is actually correct. The first argument from the key events is actually the object itself, so you should be able to do, e.g.
listeners:{
keyup:function(comboBox){
var value = comboBox.getValue() || comboBox.getRawValue();
console.log(value);
}
}
Swapping you the value getting method as appropriate.
I found that the combo already has a quick search behaviour, I just have to set queryMode on 'remote' and some other small configurations. More details here:

In an angular form with pre-populated value, I would want to create an object that is consist of fields that are dirty and valid, that is when user change the holder value and that change is valid.
I have no problem with simple validation, as I found some examples in the doc, but how can one handle such an object that is conditioned on dirty and valid?
I found good example where we can see validation status:

Hope it will help you,
I would like to display a default value (that I already set using setDefaultSuggestionsFromText()) when there is no suggestion displayed for the user entered value. Thanks for your help!
You need a SuggestOracle that always returns a suggestion. You could easily build one that wraps your current SuggestOracle and returns your canned suggestion when the wrapped oracle returns none.
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.
OK, let's start with the Html.Textbox. It is supposed to contain text read from a file. The file read is based on what the user picks from a dropdown list.
The first time it is fine. The user picks a value from the dropdown list. The controller uses that value to read some text from a file, and returns that text to the view via the view model. Everything is fine.
THen the user picks another value from the dropdown list. The controller reads a new value from a file and returns it via the view model. Debugging to the LINE BEFORE THE HTML.TEXTBOX is set in the view shows that the model contains the correct value. However, the textbox itself still shows the PREVIOUS value when the page displays!
If I switch from Html.Textbox to a plain input, type="text" html control, everything works fine. That's not so hard, but the same thing happens with my dropdown list -- I can't set the selected value in code. It always reverts to whatever was chosen last. Rendering a "select" tag with a dynamically-generated option list is a pain. I would love to be able to use Html.Dropdown.
What am I missing here?? This is such a simple thing in webforms!
When you post a form, the values that are posted are put into ModelState. When the HtmlHelper renders an html iunput element, e.g. Html.TextBoxFor(x => x.FirstName), it'll search various locations to get the value for the textbox... ModelState is before ViewData.Model in the list of locations. So there for, the previously posted value will appear in your textbox.
To fix this you could clear the ModelState value or update the ModelState value. BUT I would kinda view that as a hacky way of getting around the problem.
The real issue has more to do with the flow of the posts and requests. I would personally look into that and maybe implement the PRG (Post Redirect Get) pattern.
HTHs,

Following on from what Charles/Charlino said:
Model binding updates the ModelState object, which contains validation and model binding errors that are collected during model binding.
Inside an action method, model binding has occurred already to update the model, and generated the ModelState object. If you now update the value on the model inside the action, you must also manually update the model state (since the helpers use it to generate their HTML). Below is an example:
model.CaptchaIsValid = CaptchaService.ValidateAndExpireCaptcha(model.CaptchaAttempt);
if (!model.CaptchaIsValid)
{
ModelState.AddModelError("CaptchaAttempt", "Incorrect - please try again");
}
// I'll clear the value on each attempt, to force them to re-enter a CAPTCHA.
model.CaptchaAttempt = string.Empty;
// Since I updated the model, I must create a new ValueProvider result...
ValueProviderResult clearedValue = new ValueProviderResult(
model.CaptchaAttempt,
model.CaptchaAttempt,
CultureInfo.CurrentCulture);
// ... and update the ModelState's value.
ModelState.SetModelValue("CaptchaAttempt", clearedValue);
The biggest issue I see here is that you are trying to do a postback within MVC. That model is really not supported, and is actually way more trouble than it is worth (as it seems you are finding out). I would recommend using Ajax to update the contents of the dropdown dynamically.
