How can I check if any of the fields in the model are empty or empty?
I have a model $userModel
. I want to check if any fields for this model are empty or null
.
I am currently doing this with a large if statement.
if(!empty($userModel->name) && !empty($userModel->address) ... && !empty($userModel->email))
{
// All fields have values
}
This way works, but if later I need to add another field to the model, then I need to go back to the if and add another condition &&
.
How can I do this in one check?
Is there something like: $userModel::model()->areAllFieldsFilled();
Additional info: The model is already saved in the db and the user doesn't need to enter data. This is just me, checking how complete a particular model is, by no means will it be mandatory for all these fields in the database, just a few. Usually things like $userModel->bio
, stay null
.
I want to avoid checking 5-10 fields. I don't want to be giant if it needs to be saved when the model changes.

PHP allows you to iterate over the properties of an object . Validation for each property can be simplified with empty () :
$allHaveValues = TRUE;
foreach ($userModel as $key => $value) {
if (empty($value)) {
$allHaveValues = FALSE;
break;
}
}
if ($allHaveValues) {
// Do something...
}

Use empty()
if(!empty($userModel->name)) { .. }
- "" (empty line)
- 0 (0 as integer)
- 0.0 (0 as float)
- "0" (0 as string)
- NULL
- FALSE
- array () (empty array)
- $ var; (declared variable, but no value)
Update
$modelData = array($userModel->name, $userModel->address, $userModel->email);
if(!in_array('', $modelData) && !in_array(null, $modelData)) { .. }
Or you can use array_intersect
-
if(empty(array_intersect(array('', null), $modelData))) { .. }

I guess you don't need to do this.
All you need to do is specify your validation rules.
For example:
<?php
class Brand extends CActiveRecord
{
public function tableName()
{
return 'brand';
}
public function rules()
{
return [
['name, country', 'on' => 'insert'],
['name', 'type', 'type' => 'string', 'on' => 'insert'],
['name', 'length', 'max' => 100, 'on' => 'insert'],
['name', 'type', 'type' => 'array', 'on' => 'search'],
['country', 'type', 'type' => 'string'],
['country', 'length', 'max' => 50],
];
}
}
When you use this model, you just need to check this model for $model->validate()
, and if it fails, show errors with $model->getErrors()
. In addition, you can specify which rule script you want to use. For example: a $model->senario = 'search';
validation rule will be used search
and the property name
should be an array. But when the script name insert
should be a string no longer than 100.
In my examples the fields: name, country - are required for insert ( ['name, country', 'on' => 'insert']
).
