How Can I Efficiently Chain WHERE Clauses for Complex Queries in Laravel Eloquent?

Chaining Where Clauses for Complex Queries with Laravel Eloquent

In Laravel Eloquent, defining complex queries often involves chaining multiple where clauses. While this approach is functional, it can appear tedious and unorganized.

However, there are better ways to structure such queries.

Nested Array Approach (Laravel 5.3 )

Laravel introduced the ability to pass a nested array to the where method, allowing you to specify multiple conditions granularly.

$query->where([
    ['column_1', '=', 'value_1'],
    ['column_2', '<>', 'value_2'],
    // ... additional conditions
]);

Array Variable Approach (Pre-Laravel 5.3)

In earlier versions of Laravel, you could pass an array of conditions directly to the where method. However, this approach only works if all conditions require the AND operator.

$matchThese = ['field' => 'value', 'another_field' => 'another_value'];
$results = User::where($matchThese)->get();

Alternative Array Wheres (Pre-Laravel 5.3)

Another option in pre-Laravel 5.3 versions was to use the orWhere method to combine multiple groups of conditions. This resulted in an OR condition between the groups.

$matchThese = ['field' => 'value', 'another_field' => 'another_value'];
$orThose = ['yet_another_field' => 'yet_another_value'];
$results = User::where($matchThese)
    ->orWhere($orThose)
    ->get();

By utilizing these techniques, you can write more efficient and readable queries, even when dealing with complex WHERE conditions.
