You might find that the data is not rendering correctly. Instead of seeing the expected names and surnames, you observe garbled output in your browser.

Diagnosing the Issue

The primary problem stems from how you're passing data to the Vue component. When using @ json, if you do not escape the PHP code properly within Blade, it can cause issues when passing the JSON-encoded data as a prop.

Here are common symptoms of poor data handling:

The Vue component doesn't render as expected.

You observe strange characters or JSON formatting errors in the output.

The component's template, such as 'Items:', fails to appear.

The Solution

Correct Usage of Blade Syntax

There are a couple of ways to get around this issue effectively:

Understanding Vue Binding

When you define props in your Vue component, such as :items, it acts as a shortcut for v-bind—meaning it expects a JavaScript expression. This is crucial to remember, as putting quotes around a directive can lead to unexpected behavior.

Conclusion

By properly escaping PHP or using @ json without quotes, you can seamlessly pass a multidimensional PHP array from Laravel to a Vue component. This allows you to effectively utilize your data for dynamic rendering in your application.

If you encounter any further issues, double-check your Blade syntax and ensure the data format being passed aligns with what your Vue component expects. Happy coding!
