Pass PHP array onto Vue component using props

  • Building a Laravel app with a few Vue components
  • Want to pass a PHP array onto a Vue component using props

Here's an example of such PHP array:

["Foo" => 100, "Bar" => 50]

Great. Here's my attempt at passing them onto the Chart component:

<Chart points="{!! json_encode($points) !!}"></Chart>

This looks fine, but the strings (Foo and Bar) inside the $points array get encapsulated with " (double quotes) when using json_encode(). This means that whenever the 1st string appears in the array, the browser thinks that the " is meant to close the points attribute.

Here's what you get to see in the browser:

<Chart points="{">Foo":100,"Bar":50}"</Chart>

How do I go about this? I have been struggling with this for hours now, and I can't wrap my head around it.

  • Can't use " (double quotes) since the browser interprets it as the closing quote for an attribute and messes up the HTML
  • Can't use ' (single quotes) since that's invalid JSON (and json_encode doesn't support it)

<Chart points='{!! json_encode($points) !!}'></Chart>

Just use singular quotes.

Starting with Laravel 5.5 you can use the @json directive.

<Chart points=@json($points)></Chart>
