Difference between @yield and @include in Laravel Blade

  • 772

Hello people, I wanted to know if there is any technical difference, in principle and for the function that I give them, they would be working the same.

It seems clearer to use @include. but I would like to know if there is any detail that I should know so as not to abuse it.

  1. What I see as a difference is how it is implemented in the code, for example.

    If you have a @includelike to implement in PHP is that it is only for a specific code that you call from another site, instead @yieldyou put a "name" to put it in some way. That is, @yield('contenido')and that content can be displayed from other views that are referenced to that @yield.

    Obviously in code you make the extension to where that yield.

    That's how I see it. The one @yieldfor many calls and the @includeone for a specific one.

    @yieldit will look for a section established in the current page (or view) and it will show it in that place, it can also add a default value in case there is nothing in said section.

    This @yield('titulo', 'Mi sitio')will include whatever is defined in @section Blog @endsectiona view (the Blog text in this case), if nothing is defined, it will display the My Site text.

    The source code for @yield is:

    protected function compileYield($expression)
{
    return "<?php echo \$__env->yieldContent{$expression}; ?>";
}

public function yieldContent($section, $default = '')
{
    $sectionContent = $default;

    if (isset($this->sections[$section])) {
        $sectionContent = $this->sections[$section];
    }

    $sectionContent = str_replace('@@parent', '--parent--holder--', $sectionContent);

    return str_replace(
        '--parent--holder--', '@parent', str_replace('@parent', '', $sectionContent)
    );
}

    @includeit will simply include another view in the current one, in such a way that it @include('blog.articulo')will search for the file views\blog\articulo.blade.phpand include it in the current view, all its content.

    The source code for @include is:

    protected function compileInclude($expression)
{
    if (Str::startsWith($expression, '(')) {
        $expression = substr($expression, 1, -1);
    }

    return "<?php echo \$__env->make($expression, array_except(get_defined_vars(), array('__data', '__path')))->render(); ?>";
}
