PHP code inside Laravel 5 Blade Template

Question

I have to place some PHP code inside Laravel 5 Blade Template. Like below

@foreach ($farmer->tasks as $task)
    @if ($task->pivot->due_at) < date(now))
        $style = 'alert alert-danger';
    @elseif ($task->pivot->due_at) > date(now))
        $style = 'alert alert-success';
    @else
        $style = '';
    @endif
@endforeach

Which is the actual procedure to place PHP code inside Laravel 5 Blade Template ??

Answer 1

According to documentation, in Laravel 5.2 and newer you can use the following code:

@php
{{-- php code here --}}
@endphp

Alternatively, you can extend the Blade templating engine as it's described here.

If neither of the above solutions is suitable, you are stuck with the answers given by @Armen and @Gonzalo

Answer 2

Just open and close php tags: <?php $style = '...'; ?>

Answer 3

Laravel recipes suggest a simple but effective way to do it without including the php tags

{{--*/ $var = 'test' /*--}}

{{-- --}} works as a blade comment / and / reverts the effect of comment resulting on

<?php $var = 'test' ?>

The problem is that is longer than including php tags :-(

Answer 4

The following new NewBladeCompiler will use @{ }} for accepting all php codes like variable assigning, class declaration etc. e.g. @{ $variable = 0; }} will be compiled to <?php $variable=0; ?>

    <?php

use Illuminate\View\Compilers\BladeCompiler;

class NewBladeCompiler extends BladeCompiler
{

    /**
     * Get the echo methods in the proper order for compilation.
     *
     * @return array
     */
    function getEchoMethods()
    {
        $methods = [
            'compileRawEchos'     => strlen(stripcslashes($this->rawTags[0])),
            'compileEscapedEchos' => strlen(stripcslashes($this->escapedTags[0])),
            'compileRegularEchos' => strlen(stripcslashes($this->contentTags[0])),
            'compilePhpEchos'     => strlen(stripcslashes("@{"))
        ];

        uksort($methods, function ($method1, $method2) use ($methods) {
            // Ensure the longest tags are processed first
            if( $methods[$method1] > $methods[$method2] )
            {
                return -1;
            }
            if( $methods[$method1] < $methods[$method2] )
            {
                return 1;
            }
            // Otherwise give preference to raw tags (assuming they've overridden)
            if( $method1 === 'compilePhpEchos' )
            {
                return -1;
            }
            if( $method2 === 'compilePhpEchos' )
            {
                return 1;
            }
            if( $method1 === 'compileRawEchos' )
            {
                return -1;
            }
            if( $method2 === 'compileRawEchos' )
            {
                return 1;
            }
            if( $method1 === 'compileEscapedEchos' )
            {
                return -1;
            }
            if( $method2 === 'compileEscapedEchos' )
            {
                return 1;
            }
        });

        return $methods;
    }

    function compilePhpEchos( $value )
    {
        $pattern  = sprintf('/(@)?%s\s*(.+?)\s*%s(\r?\n)?/s', "@{", "}}");
        $callback = function ($matches) {
            $whitespace = empty($matches[3]) ? '' : $matches[3] . $matches[3];
            return $matches[1] ? substr($matches[0], 1) : '<?php ' . $matches[2] . ' ?>' . $whitespace;
        };
        return preg_replace_callback($pattern, $callback, $value);
    }

}

?>
