In this short snippet, you will learn how to create multiple where clause queries using Laravel Eloquent to construct a more complex condition the easy way so let's get started.
Method 1: Laravel Basic Query Multiple WHERE Condition
To basic way to query with multiple where clauses are to chain the "where" method continuously and passing in the condition as follows.
<?php
$results = Post::query()
->where('post_status', '=', 1)
->where('user_id', '=', 1)
->where('published_code', '=', 1)
->get();Method 2: Laravel Query Multiple WHERE Condition With Array
Another approach is to pass in an associative array that contains the different types of conditions.
<?php
$results = Post::query()
->where([
['post_status', '=', 1],
['user_id', '<>', 1]
])
->get();Or if you want to check for "greater" and "lower" operators then you can use the "whereColumn" like below.
<?php
$users = DB::table('users')
->whereColumn([
['first_name', '=', 'last_name'],
['updated_at', '>', 'created_at']
])->get();Method 3: Multiple WHERE Condition with Model Scopes
The next method is to define your condition from within the Model class itself, this way you will be able to have a more expressive and elegant syntax.
<?php // app/Models/Post.php
class Post extends Model
{
public function scopeActivePost($query)
{
return $query
->where('post_status', '=', 1)
->where('user_id', '=', 1);
}
public function scopeMainUser($query)
{
return $query
->where('post_status', '=', 1)
->where('user_id', '=', 1);
}
}Now in your controller or other parts of your application, you can call the scope while building the query.
<?php Post::activePost()->mainUser()->get();
Method 4: Laravel Multiple WHERE Condition With Sub Query
The next method is to use a sub-query to define the WHERE condition and it will like below.
<?php
Post::query()
->where('post_status', '=', 1)
->whereNotNull('created_at')
->whereNotNull('updated_at')
->where(function($query){
return $query
->whereNotNull('user_id')
->where('your_condition_here', '=', 'your_value_here');
});
