Laravel：如何在 {{ }} 内实现 if 语句

Question

I'm having to pass search filters in links in my laravel app on various occasions. The following statement was working fine in laravel 4, but now I'm converting it to laravel 8 and its giving me error now.

{{ link_to_route('workprocess.edit', 'Edit Work Process', array($workprocess->id, json_encode($searchFilters)), array('class' => 'btn btn-sm btn-warning')) }}

Error

Missing required parameters for [Route: workprocess.edit] [URI: workprocess/edit/{workprocess}/{search?}]. (View: D:\xampp\htdocs\compliance.local\resources\views\home.blade.php)

Reason $searchFilters is empty sometimes since the same template is being used for searching as well. $searchFilters = array('fromdate' => '', 'todate' => '', 'name' => '', 'type' => '');

I want to put an if statement inside {{ }} for json_encode($searchFilters) so that I don't have to write code for two links as there are quite a few other such occurances.

Answer 1

This would be my solution;

Where $searchFilters is set:

if (empty($searchfilters)) {
    $searchfilters = 1;
};

and add a ternary inside json_encode method:

json_encode(empty($searchFilters)?= 1: $searchFilters; '');

Answer 2

You can add an if statement using shorthand for example:

{{ $var === "hello" ? "Hi" : "Goodbye" }}
