Hello Readers,

Below blog shows the call of the model from one component to another component.

For Example - We have a two different components in Joomla :

>> comp1

comp1->model->m1
  model: m1

comp1->controller->c1
  controller: c1
>> comp2

comp1->model->m2
  model: m2

comp1->controller->c2
  controller: c2

In the above component, call the one component model to another component model.

Then, we use the below code inside that component model m2 where we call the component model m1:

Code Example :

JModelLegacy::addIncludePath(JPATH_SITE . '/components/comp1/models', 'Comp1Model');
$model = JModelLegacy::getInstance('m1', 'Comp1Model');
$result = $model->name of the model function();
print_r($result); die;

In the above code,

Step 1 : We use the addIncludePath() method and adds a directory(JPATH_SITE . '/components/comp1/models', 'Comp1Model') means the path of the component model.

Parameter's are :

1. the path of the directory.
2. class prefix for models.

Step 2 : Then we use the getInstance() method. In this method parameters are:

1.$type
The model type to instantiate. (m1)

2.$prefix
Prefix for the model class name.(Optional) (Comp1Model)

3.$config
Configuration array for model. (Optional).

Step 3 : Lastly, we use the name of the model function ($model->name of the model function()) which we used inside the component.

Advantage of using one component model to another component :
1. Reusability of a certain function.(suppose if we reuse the certain function that belongs in a model outside of your current scope).
2. Helps to save time and reduce the duplicacy of the functions in both the components.
