Definition of CakePHP contain
CakePHP is an open-source framework that provides the dynamic behavior of programming. Additionally, CakePHP provides the containable behavior, which helps filter the operation and allows us to limit the model. In other words, we can say that as per our requirement, we can cut down the database into two-mode wear and tear. Furthermore, after the implementation of CakePHP contains, the application’s overall performance will be improved. Furthermore, by using CakePHP containers, we implement streamlining and binding during the software implementation, which can help improve the application’s performance.
What is CakePHP contain?
ContainableBehavior. This exemplary conduct permits you to channel and restrict model track-down tasks. Utilizing Containable will assist you with eliminating unnecessary mileage on your data set, speed up, and general execution of your application. In addition, the class will help you search and channel your information for your clients perfectly and predictably.
Containable permits you to smooth out and improve the procedure on your model ties. It works by briefly or forever modifying the relationship of your models. It does this by utilizing the provided controls to produce a progression of bindModel and unbindModel calls. However, since Containable changes existing connections, it won’t permit you to confine results by far-off affiliations. Rather you ought to allude to Joining tables.
How to Use CakePHP contains method?
Let’s see how we can use the contain method in CakePHP.
An essential inquiry in CakePHP 3.0 is not the same as the ones utilized in CakePHP 2.0. In 3.0, the ORM (Object-social planning) utilized for information base administration-related tasks has changed. For instance, if ‘Emp’ is a model and we need to bring a portion of the fields utilizing the inquiry manufacturer, the question would look as beneath:
$results=$emp->find() where(['id >'=>1]) toArray();
Using the above query, we will find all the records whose id is greater than or equal to 1. We illustrate the final result of the above implementation using the following screenshot.
Now let’s see another example as follows.
How about we take this model? There are two tables, for example, ‘Dept’ and ‘Emp,’ with numerous connections. On the off chance that we want to bring the Dept data related with Emp, then, at that point, we have a possibility for the ‘contain’ technique for CakePHP. In form 3.0, we have full command over the related models. Here is the inquiry:
$results=$emp->find() contain(['Emp', Dept]) where(['id >'=>1]) toArray();
In the above example, we try to implement the contain method as shown; here, we join two different and get results into a single table. The above implementation we illustrated by using the following screenshot as follows.
So in this way, we can implement the contain method, as well as we can also add more methods as per our requirement such as ascending, descending, or sometimes we need to filter the record that is associated with another table at that time we can also use the contain method.
CakePHP contains a find statement
Now let’s see how we can use find statements in CakePHP as follows.
As expressed previously, one of the Model layer’s jobs is getting information from different capacities. The CakePHP Model class accompanies a few capacities that will assist you with looking for this information, sorting it, paginating it, and channeling it. The most widely recognized work you will use in models is model:find()
find (string $specified type = 'specified type', array $params = array())
Using the above syntax, we can implement the find statement; Find is the multifunctional workhorse of all model information recovery capacities. $type can be ‘all’, ‘first’, ‘count’, ‘list’, ‘neighbors’ or ‘strung’, or any custom locater you can characterize. Remember that $type is case-delicate. Utilizing a capitalized character (for instance, all) won’t deliver the expected outcomes.
$params are utilized to pass all boundaries to the different kinds of find () and have the accompanying conceivable keys, of course, which are all discretionary:
Now let’s see different find methods as follows.
We can use this method if we need to print the first result or say that single result at that time.
find('first', $All parameter)
In the above syntax, we use the find method first; also, we need to pass all parameters.
$result = $this -> Emp-> find('first');
After executing the above statement, it returns the single record from the Emp table; the implementation of the above statement is illustrated by using the following screenshot.
It is used to return the integer value as per our requirement.
find('count', $All parameter)
In the above syntax, we use the find method with the count method, and also here, we need to pass all parameters.
$result = $this -> Emp-> find('count');
We illustrated the final result of the above statement using the following screenshot.
It is used to return a variety of different possible outcomes. Indeed, it is the component utilized by all find ( ) variations and paginates.
find ('all', $All parameter) find('list')
It is used to return an ordered cluster, helpful for any spot where you would need a rundown, for example, for populating input select boxes.
find ('list', $All parameter) find('threaded')
It is used to return a settled cluster and is fitting to utilize the parent_id field of your model information to fabricate settled outcomes.
find ('threaded', $All parameter)
So in this way, we can implement the find statement as per our requirement; we can also write the above statement inside the function, depending on the requirement.
