Theming “field collection” in node pages drupal 7

collectionsdrupaldrupal-7drupal-themingfield

Drupal 7 "field collection" – If I want to theme a node page which has a "field collection", how do I go about separating the fields for customization? It seems thus far that only print render($content['field_collection_name']); outputs the result. The problem is that I can't figure out how to isolate the fields for theming.

I've created a node–content_type.tpl.php for this purpose but now stuck dead in the water. Would really appreciate someone saving the day for me.

Solved as follows:

Some of the links from below are really very helpful so do look, though, I've done something like this –
Enter dsm(print_r($variables));on node to be rendered in my case node--content_type.tpl.php with field collection to find out the arrays and field values needed, then hide of course.

The styling part then would look something like this

<div>class="class-for-label-here">My Desired Label - <span class="my-field-class-here"><?php print render($content['my_desired_field_here']['#items'][0]['value']); ?></span></div>

Best Answer

There's a fairly good conversation about this same thing going on here:

Main answer is theming with template field--your-field-collection-name.tpl.php

After that you just need to figure out how to retrieve the contents from the arrays and/or objects!

Java – Iterating through a Collection, avoiding ConcurrentModificationException when removing objects in a loop

Iterator.remove() is safe, you can use it like this:

List<String> list = new ArrayList<>();

// This is a clever way to create the iterator and call iterator.hasNext() like
// you would do in a while-loop. It would be the same as doing:
//     Iterator<String> iterator = list.iterator();
//     while (iterator.hasNext()) {
for (Iterator<String> iterator = list.iterator(); iterator.hasNext();) {
    String string = iterator.next();
    if (string.isEmpty()) {
        // Remove the current element from the iterator and the list.
        iterator.remove();
    }
}

Note that Iterator.remove() is the only safe way to modify a collection during iteration; the behavior is unspecified if the underlying collection is modified in any other way while the iteration is in progress.

Source: docs.oracle > The Collection Interface

And similarly, if you have a ListIterator and want to add items, you can use ListIterator#add, for the same reason you can use Iterator#remove — it's designed to allow it.

In your case you tried to remove from a list, but the same restriction applies if trying to put into a Map while iterating its content.

C# – the difference between a field and a property

Properties expose fields. Fields should (almost always) be kept private to a class and accessed via get and set properties. Properties provide a level of abstraction allowing you to change the fields while not affecting the external way they are accessed by the things that use your class.

public class MyClass
{
    // this is a field.  It is private to your class and stores the actual data.
    private string _myField;

    // this is a property. When accessed it uses the underlying field,
    // but only exposes the contract, which will not be affected by the underlying field
    public string MyProperty
    {
        get
        {
            return _myField;
        }
        set
        {
            _myField = value;
        }
    }

    // This is an AutoProperty (C# 3.0 and higher) - which is a shorthand syntax
    // used to generate a private field for you
    public int AnotherProperty { get; set; } 
}

@Kent points out that Properties are not required to encapsulate fields, they could do a calculation on other fields, or serve other purposes.

@GSS points out that you can also do other logic, such as validation, when a property is accessed, another useful feature.
