Question

        @foreach ($modules as $module)

                @if ($module->name === "h_car_positions")   $module_name == "history_car_positions";    @endif


            <tr>
                <td>{{ $module->id }}</td>
                <td><a href="{{ url(config('laraadmin.adminRoute') . '/modules/'.$module->id) }}">{{ $module->name }}</a></td>
                <td>{{ $module->name_db }}</td>

                <td>{{ Module::itemCount( $module_name ) }}</td>
                <td>
                    <a href="{{ url(config('laraadmin.adminRoute') . '/modules/'.$module->id)}}#fields" class="btn btn-primary btn-xs" style="display:inline;padding:2px 5px 3px 5px;"><i class="fa fa-edit"></i></a>

                    <a href="{{ url(config('laraadmin.adminRoute') . '/modules/'.$module->id)}}#sort" class="btn btn-success btn-xs" style="display:inline;padding:2px 5px 3px 5px;"><i class="fa fa-sort"></i></a>
                    <a module_name="{{ $module->name }}" module_id="{{ $module->id }}" class="btn btn-danger btn-xs delete_module" style="display:inline;padding:2px 5px 3px 5px;"><i class="fa fa-trash"></i></a>
                </td>
            </tr>
        @endforeach

i want to assign history_car_positions to $module name when the if statment is true how to do that in blade

Answer 1

I should first note that your syntax is incorrect - you're comparing ( == ), not assigning ( = ).

But Blade, being an interpreter, has its own control structure for raw PHP.

However, if you're simply passing this variable into itemCount , you may want to evaluate and assign this in your view, rather than directly in the template. It'll be much cleaner for you to maintain.

Answer 2

You could try the php directive laravel docs

@if ($module->name === "h_car_positions")
   @php
      $module_name = "history_car_positions"; // use = instead of ==
   @endphp
@endif

Answer 3

使用php标签

@if ($module->name === "h_car_positions")  <?php $module_name = "history_car_positions"; ?> @endif
