How to Search for Emails Within a JSON Column in Laravel?

Eloquent Queries for Searching JSON Columns

In Laravel, searching JSON columns can be a challenge. This article will delve into a specific scenario involving a "To" column that stores email addresses in a JSON format.

The Problem

Given a "To" column with JSON data like this:

<code class="json">[
    {
        "emailAddress": {
            "name": "Test", 
            "address": "test@example.com"
        }
    }, 
    {
        "emailAddress": {
            "name": "Test 2", 
            "address": "test2@example.com"
        }
    }
]</code>

The goal is to retrieve emails sent to "test@example.com." Using whereJsonContains('to->emailAddress->address', 'test@example.com') returns no results.

The Solution

The issue lies in the use of the arrow operator (->). In JSON arrays, the arrow operator is not supported. Instead, the double square bracket notation ([['emailAddress' => ['address' => 'test@example.com']]]) should be used.

The corrected query is:

<code class="php">DB::table('emails')
   ->whereJsonContains('to', [['emailAddress' => ['address' => 'test@example.com']]])
   ->get()</code>

This query will return all emails that include "test@example.com" in the "To" column.
