Check if Array is Empty in Blade using Laravel

Blade is the simple, yet powerful templating engine that is included with Laravel. It allows you to easily create reusable templates with concise, secure syntax. In this article, we'll explore how to check if an array is empty in Blade using Laravel.

Checking if Array is Empty

1. Using Empty() Function

The empty() function in PHP returns true if the variable has an empty value, and false otherwise. Therefore, we can use this function to check if an array is empty in Blade.

Syntax

@if(empty($array))
    <p>The array is empty.</p>
@endif

Example

@php
    $users = [];
@endphp

@if(empty($users))
    <p>No users found.</p>
@else
    <table>
        <thead>
            <tr>
                <th>Name</th>
                <th>Email</th>
            </tr>
        </thead>
        <tbody>
            @foreach($users as $user)
            <tr>
                <td>{{ $user->name }}</td>
                <td>{{ $user->email }}</td>
            </tr>
            @endforeach
        </tbody>
    </table>
@endif

Output

If the $users array is empty, the output will be:

No users found.

If the $users array is not empty, the output will be a table of users.

Explanation

The PHP empty() function checks if the $users array is empty, and if it is, the text "No users found." is displayed. If the array is not empty, the table is displayed with the user information.

Use

You can use this method to check if a variable is an empty array before displaying a table, list, or other element on your page that depends on that array having values.

Important Points

• The empty() function is used to check if a variable is empty.
• If the array is empty, the message "No users found." is displayed.
• If the array is not empty, the table with user information is displayed.

Summary

In this article, we explored how to check if an array is empty in Blade using Laravel. By using the empty() function in PHP, we can easily check if an array is empty and display an appropriate message to the user. Blade is a powerful templating engine that makes it easy to create reusable templates with concise, secure syntax. By using these two technologies together, we can create elegant, dynamic web applications that are easy to maintain and extend.
