laravel (1) routing, parameter passing, blade laravel how to read laravel development tutorial laravel framework

1. Every time you access laravel, you will be directed to the routes.php file
2. Usually a route will be handed over to a controller method for processing

controller

1. Create controller
｀php artisan make:controller controllername｀
Note: ｀php artisan make:controller controllername　–plain｀does not carry custom methods
2.Use controller
Routes: Route::get('/','SitesController@index');
SC:

<code><span>public</span><span><span>function</span><span>index</span><span>()</span> {</span><span>return</span><span>"sjming"</span>;
    }</code>

3. Parameter passing
(1)Single value:
SC:

<code><span>public</span><span><span>function</span><span>index</span><span>()</span> {</span><span>$name</span> = <span>'sjming'</span>;
        <span>return</span> view(<span>'welcome'</span>)->with(<span>'name'</span>,<span>$name</span>);
    }</code>

(2) array

<code><span>return</span> view<span><span>(<span>'welcome'</span>)</span>-></span><span>with</span>([
    <span>'name'</span><span>=></span>$name,
    <span>'first'</span><span>=></span><span>'su'</span>
]);</code>

(3) as a parameter of view

<code><span>$data</span>=[];
    <span>$data</span>[<span>'first'</span>]=<span>'123'</span>;
    <span>$data</span>[<span>'second'</span>]=<span>'456'</span>;
    <span>return</span> view(<span>'sites.about'</span>,<span>$data</span>);</code>

(4) php’s compact

<code><span>$fir</span>=<span>'123'</span>;
   <span>$sec</span>=<span>'456'</span>;
   <span>return</span> view(<span>'sites.about'</span>,compact(<span>'fir'</span>,<span>'sec'</span>));</code>

4. Parameter usage
Escape method: {{}} //The html in it is not interpreted
Unescaping method: {!! !!} //The html explanation

blade template

1. ＠yield('xxx'),@extends('xxx')
2. @section('xxx'),@ stop

').addClass('pre-numbering').hide(); $(this).addClass('has-numbering').parent().append($numbering); for (i = 1; i ').text(i)); }; $numbering.fadeIn(1700); }); });

The above has introduced laravel (1) routing, parameter passing, and blade, including the content of laravel and blade. I hope it will be helpful to friends who are interested in PHP tutorials.
