I started on developing custom form elements and decorators. I save them to the zend/library/form folder is that right?
And how do I use this custom elements?
$d = new My_Form_Element_Date('dateOfBirth');
$d->setLabel('Geburtsdatum:')
->setValue('20 April 2009');
$this->addElements(array($d));
Gives me the error that the location of the class could not be specified.
Any ideas?
I need to register the namespace:
Zend_Loader_Autoloader::getInstance ()->registerNamespace('My_');
That's all!

I am just learning Symfony and maybe I am doing something wrong.
I created a simple form with the possibilty to upload a file. After choosing the file the filename doesn't show up in the form.
Screen 1 - Choose picture
Screen 2 - Filename isn't shown
The picturename is correctly saved to the database, so it must be there :)
I used ->add('picture', FileType::class, ['required' => false])
Can someone push me in the right direction. I am trying to figure this out for the last 2 hours.
There is a "bug" with that type of field in Symfony when using the Bootstrap form theme.
If you are using Symfony's Boostrap form theme
# config/packages/twig.yaml
twig:
default_path: '%kernel.project_dir%/templates'
form_themes:
- 'bootstrap_4_horizontal_layout.html.twig'
I would recommend adding some Javascript to fix this issue.
$('.custom-file-input').on('change', function(event) {
let inputFile = event.currentTarget;
$(inputFile).parent().find('.custom-file-label').html(inputFile.files[0].name);
});
Note that I'm using ES6 syntax here, for better compatibility with old browsers, you might want to use ES5 if you are not using a transpiler. Also, I using the custom-file-label class since I'm using Symfony's Bootstrap 4 form theme, you might want to adjust if you are using another theme.
..files[0].name is used since your FileType could accept multiple files.
I have same problem as of How to add standard field to custom layout of SugarCRM 7
I have created a custom view(followed these steps http://www.insightful.com.au/sugarcrm-how-do-i/creating-custom-button-sugar-7) in SugarCRM7 but not getting how should I add standard fields to this layout
I am new to SugarCRM7 and seeking for help :(
You can use metadata to provide the list of fields and then use the {{field}} Handlebars helper in your template to insert them into your HTML.
To see examples of how to use field helper see dashablelist.hbs or preview.hbs in Sugar 7.5.
I am creating a Joomla 2.5 component. In the backend I created a model/view/controller 'Members' which shows a grid. I also created an MVC 'Member' which is used to add or edit a member from the grid. So far so good.
Now, I would like to add a frontend view that is very similar to the 'Member' view in the backend, but this one is meant for visitors so they can subscribe themselves. It has to look more user friendly than the backend form, so I will create a slightly different 'Member' view in the frontend, but I would really like to reuse the form file (/administrator/components/mycomponent/models/forms/member.xml) from the backend!
So, my question is how my frontend view can find and use that backend form?
You definitely have to load it in the model. Your model has to extend JModelAdmin and then the getForm function has to load the form
public function getForm($data = array(), $loadData = true) {
// Get the form.
JForm::addFormPath(JPATH_COMPONENT_ADMINISTRATOR . '/models/forms');
JForm::addFieldPath(JPATH_COMPONENT_ADMINISTRATOR . '/models/fields');
$form = $this->loadForm('com_dpattachments.attachment', 'attachment', array('control' => 'jform', 'load_data' => $loadData));
if (empty($form)) {
return false;
}
....
}
I'm using the same approach in my DPAttachments component, it is for Joomla 3.1 but the main code, to use the same model and form on the front and back, should also run on Joomla 2.5. Here is the link to the getForm function
https://github.com/Digital-Peak/DPAttachments/blob/master/com_dpattachments/admin/models/attachment.php#L102
If you are following Joomla MVC guidance your frontend should be able to pick-up the forms automatically.
In your view (though it should request it from the model actually) you can write:
$formsPath = JPATH_ADMINISTRATOR.DS.'components'.DS.'com_mycom'.DS.'models'.DS.'forms';
$this->form = JForm::getInstance('myform', $formsPath.DS.'myform.xml');
You can also look at the summer of code cm_config project which pulls the config forms and the templateDetails form to the front end using JSON. https://github.com/Buddhima/joomla-cms/tree/gsoc_com_config or the com_services branch.
I have been attempting to create a form where a user can simply press a button and the form will add a new field for the user to use. I have 2 of these dynamically added field types.
Firstly a field where a user can upload files, by pressing the add button another field is pasted underneath the current field and is ready for use.
I have followed an old guide on how to get this done with a bit of ajax and jQuery.
This guide to be exact: http://www.jeremykendall.net/2009/01/19/dynamically-adding-elements-to-zend-form/
As you can see it's from 2009 and a bit outdated yet it still works under the current Zend Framework version 1.11.11
The problem however arises now that i want an edit / update version of the form. I need to populate it's fields but first of all i need to create enough fields for the data to be stored in. So when there's 3 files that have been uploaded it should create 2 additional fields and place the 3 file names in these fields ready to be edited and updated. Simply using $form->populate($stuff) is not going to work
I just have no idea how to accomplish this and the tutorial on dynamically added fields only goes as far as the addAction and not how to create the editAction under these conditions.
Is there any tutorial out there on how to create and manage forms such as these? I'm sure i am not the only one who's had the idea to builds these kind of forms?
I can add my code if there's a request for it but it's the same as the example from the guide, just a different set of elements in the form.
Adding a small example of it's use.
A user adds an item with 3 files, these files are uploaded along with a filename so in the database it appears like this : File_Id : '1' , File_Name : 'SomeFile' , File_location : 'somewhere/on/my/pc/SomeFile.txt'.
Now the user realizes he forgot a file or wants to delete a file from that list, he goes to the edit page and here i want the form to display the previously added filenames. So if there's 3 files it shows 3 and when there's 2 it shows 2 etc. How do i build a form to dynamically add fields based on the number of uploaded files and then populate them?
Any advice on how to handle this is well appreciated :)
You can make use of the semi-magic setXxx() methods of the form.
Inside the form:
public function setFiles($files) {
foreach ($files as $file) {
$this->addElement(/* add a file element */);
//do other stuff, like decorators to show the file name, etc.
}
}
In your controller:
$files = $model->getFiles();
$form = new Form_EditFiles(array('files' => $files));
By passing an array with key files you will make the form try to call the method named setFiles(), which you have conveniently provided above.
This should push you in the right direction, or so I hope at least.
If I understand you correctly you want to populate file upload fields, which is not possible because of security reasons.
Edit:
You can add Elements inside of the Controller via $form->addElement() (basicly just like the $this->addElement() statements in the Tutorial)
I have a need to create a <br/> tag in the display label for a menu item generated using Zend_navigation, but don't seem to be able to find a way to do so.
My navigation item is defined in the XML config as:
<registermachine>
<label>Register your Slitter Rewinder</label>
<controller>service</controller>
<action>register</action>
<route>default</route>
</registermachine>
I want to force a tag in the output HTML between 'your' and 'slitter', such that it appears on two line as below:
Register your
Slitter Rewinder
However, I can't seem to do it. obviously using in the XML breaks parsing, and using html entities means that the lable is displayed as:
Register your <br/>Slitter Rewinder
Has anyone had experience of this that can offer advice?
Thanks in advance!
there is no such option built-in you have to use a partial
$partial = array('menu.phtml', 'default');
$this->navigation()->menu()->setPartial($partial);
echo $this->navigation()->menu()->render();
http://framework.zend.com/manual/en/zend.view.helpers.html#zend.view.helpers.initial.navigation.menu
you may also try a hack with <label><![CDATA[Menu label<br/>Second line]]></label>
I found a (hacky) solution:
I updated my navigation.xml to use {br} tokens wherever a <br/> tag is required, and then amended the base Zend/View/Helper/Navigation/Menu.php file as follows:
within htmlify function, changed
$this->view->escape($label)
to
str_replace("{br}", "<br/>", $label)
I could (and probably will) override the Zend Library Menu View Helper with my own at some point, but this at least cover it for now.
there is a escapeLabels boolean used to convert html tags and it's true by default.
You can set your navigation like this
$this->navigation()
->menu()
->escapeLabels(false)
->...
