How to display value from other table using primary key - php

Question

I have implemented my project in Yii. I displaying search results in view part.
I wrote a search query for fetching the results from one table which is Recipe.
In this table name, course_id, cuisinename,type, colorie_count respectively, course_id,cuisinename, type are columns respectively.
In my controller i write code like this:
$result="SELECT * FROM recipe WHERE name LIKE '%$name%' AND `cuisinename` LIKE '$cuisine1%' AND course_id LIKE '%$course1%' AND `type` LIKE '%$type1%' AND `calorie_count` LIKE '%$calorie1%' ORDER BY recipe_id DESC LIMIT 15";
values are getting. if i give condition based to display the search result text. not displaying all name.
but those are displaying based on names.
I added below my view part condition and code:
$query= Course::model()->find("course_id=$as1");
$course2=$query->course_name;
$query1= Cuisine::model()->find("id=$as4");
$cuisine2=$query1->cuisinename;
$query3= RecipeType::model()->find("id=$as3");
$type2=$query3->recipeType_name;
<?php echo '<p align="center"> Showing results for&nbsp:&nbsp'.'Name'.$getval.',&nbsp'.'Course-'.$course2.',&nbsp'.'Cuisine-'.$cuisine2.',&nbsp'.'Type-'.$type2;',&nbsp';'</p>';
echo ',&nbsp'.'Calories-'.$calorie;
?>

Answer 1

You need to create relations between tables look there. For Recipe model it should be
public function relations()
{
return array(
'cuisine'=>array(self::BELONGS_TO, 'Cuisine', 'cuisine_id'),
'type'=>array(self::BELONGS_TO, 'RecipeType', 'type_id'),
);
}
Then you can get values as $model->cuisine->name. If you don't understand creating relations, generate models (it tables must be correct foreign keys) with gii.

Answer 2

check this article: http://www.yiiframework.com/doc/guide/1.1/en/database.arr about relations in AR
class Recipe extends CActiveRecord
{
......
public function relations()
{
return array(
'course'=>array(self::BELONGS_TO, 'Course', 'course_id'),
'cuisine'=>array(self::BELONGS_TO, 'Cuisine', 'cuisine_id'),
'type'=>array(self::BELONGS_TO, 'RecipeType', 'type_id'),
);
}
}
and related Models
class RecipeType extends CActiveRecord
{
......
public function relations()
{
return array(
'recipes'=>array(self::HAS_MANY, 'Recipe ', 'type_id'),
);
}
}
and your search query will be smth like this in controller file:
$criteria=new CDbCriteria;
$criteria->with=array(
'course',
'cuisine',
'type',
);
$criteria->addCondition('course.course_id = :filter_course'); // for ID compares
$criteria->addSearchCondition('cuisine.name', $cuisinename) //for LIKE compares
...
$criteria->params = array(':filter_course' => intval($course1));
$searchResults = Receipe::model()->findAll($criteria);
and in your view you can get related tables values:
foreach ($searchResults as $result){
echo $result->cuisine->name;
}
check also http://www.yiiframework.com/doc/api/1.1/CDbCriteria for details
you can also use this $criteria to create DataProdier for CListView or CGridView helpers in your view file
$dataProvider=new CActiveDataProvider( Receipe::model()->cache(5000),
array (
'criteria' => $criteria,
'pagination' => array (
'pageSize' => 10,
)
)
);
$this->render('search',array(
'dataProvider'=>$dataProvider
));
