I'm currently working on a Wicket 6.20 project which already has dozens of pages with TextFields and DropDownChoices. Now the requirement came up to change the default '${label}' is required. message to something more specific, depending on whether a TextField or a DropDownChoice doesn't have a value.
I know I can put Required=My Text in a properties file of the application, but that changes the message for all FormComponents. And specifying the full component path to either the TextFields or the DropDownChoices in the form of myform.mycontainer.mydropdownchoice.Required=My Text isn't feasible, since of course the structure of the Forms can differ on each page.
Ideally I'd like to put something like
org.apache.wicket.markup.html.form.DropDownChoice.Required=Please select a value for '${label}'
org.apache.wicket.markup.html.form.TextField.Required=Please enter a value in '${label}'
in my application's property file, either with or without FQCN.
Is there a way to achieve this with any of the default IStringResourceLoader that come with Wicket?
It is not necessary to provide the complete path to the components. It could be a path with just few parents:
mycontainer.mydropdownchoice.Required=My Text
mydropdownchoice.Required=My Text
If this still is not an option then you can override org.apache.wicket.markup.html.form.FormComponent#reportRequiredError() for any instance or type (e.g. MyDropDownChoice).

I want to know how to change/replace the user/contact form in Sulu i.e. https://sulu.rocks/admin/#/contacts/1/details.
I want to remove the fields for Addresses, Bank accounts, etc.
I tried to copy the vendor/sulu/sulu/src/Sulu/Bundle/ContactBundle/Resources/config/forms/account_details.xml into config/forms and removed the unnecessary fields. But that not working.
I can't find something to this in the documentation or it's hidden :D
If you add a form with the exact same key as the form you want to override, the contents of both forms are merged. In your case, the key would be contact_details. Now you can add completely new properties to the form or override existing ones by just creating a property with the same name. If you want to hide a property, you have to override it and set visibleCondition="false".
You can also have a look at this example pull request.
When creating a form in Orbeon Form Builder, you can define a list of values for a dropdown list box.
When running the form in form runner, is it possible to remove the "[Select...]" value from this dropdown list box?
I would like to restrict the possible values only to the given ones and restricting the user from selecting an "[Select...]" value when filling in the form. I hope you understand what I mean :)
Here is a screenshot
It's not possible without changes to Orbeon Forms to remove the empty option.
The best way to achieve what you want is to make the field required. When that's the case, the user will have to select a value or validation won't pass.
(The rationale for adding/keeping an empty option at the top is to force the user to make a selection. Otherwise it is possible that users might not even look at the option selected by default, and involuntarily select an incorrect option.)
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
I'm working with Symfony2 to set up a form, where a Shelf-Entity can be edited.
A shelf contains a collection of Readable-Entities (e.g. Book, Magazine, etc. - all inherit from Readable).
The user has the possibility to add more Readable-Entities (the form is extended via JavaScript) and from a dropdown he can select the type of Readable he wants to add. Depending on the selected dropdown-value, different form fields are rendered. So far so good.
Now, when the form is submitted to the server, depending on the Readable-Type the user selected in the form, a different entity-type should be instantiated.
If I don't do anything, Symfony just instantiates the base class Readable (and not Book, Magazine, etc.).
How can I tell Symfony to instantiate the correct type of Readable depending on the selected value from the dropdown?
I tried with FormEvent-Listeners, but:
in PRE_SUBMIT I only get an array containing the "raw" form data with $event->getData(), i.e. no entities have been instatiated so far. However, at this stage, I still have access to value of the dropdown.
in SUBMIT the form data was already assigned to the appropriate entities. Also the new Readable was already instatiated with the base Readable-Class. But now, I cannot access anymore the value from the dropdown.
What is the correct way to do this?
EDIT
Added a minimal Code-Example for the Shelf FormType:

Code for infinite_form_polycollection:
https://gist.github.com/anonymous/b5f0ed10ca9c52177f01
Have you tried looking at this part of the doc? As "embedding a form" seems to fit your needs.
It seems that there was something wrong with the PHP-Files of the PolyCollection in the vendor-directory, because after removing everything related to the Infinite Form Bundle from the vendor-dir and reinstalling it with composer, everything is working now. But thanks for your efforts YoannCh
I'm creating a multilingual Drupal site and trying to implement a search function, that only displays results in the current language, that the user is viewing the site through.
Using Drupals own searchfunction at /search/node it is possible to select which language to search for through the "Advanced search" options, and it works perfectly. However, I dont want to expose these language selectboxes, I just want it to only search in the current language automatically.
What's the best option to do this?
I have one solution where I create a hook_form_alter function, that sets the #default_value in the language selectboxes to the current language, and then I hide the whole "advanced options" with in css. This doesnt seem very right though.
I think the most clean solution would be to hook into Drupals form-processing process and append ex "language:en" to the input text, but I cannot get this to work.
Does anyone know if it is possible via one of the Drupal form related alter functions, to get a hold of the input text and alter it before drupal does its final processing of it?
To answer your question specifically, while using 'hook_form_alter', you have a referenced variable called '$form_state'. This stores the values in the form, and any change there will be passed further.
Also,
I think setting a default value and hiding the field is a good solution as any, only, if you are hiding it you should do it server side, while altering the form. The same field you are setting the default value to. like this:
$fieldname['#type'] = 'hidden'.
