Use Ajax to submit form instance sharing in the Lavarel framework

Because Laravel will need to add {{Csrf_field ()}} to prevent cross-site attacks when submitting data as a post, this article is mainly to share the method of using AJAX to submit forms in the Lavarel framework, let's look at it and hope to help everyone.

Laravel Introduction:

Laravel is a simple, elegant PHP Web development Framework (PHP Web framework). It frees you from the messy code of noodles, and it helps you build a perfect web app, and every line of code can be concise and expressive. "Development" should be a creative mental work, not a dull "base code".

Come to the point, because Laravel will need to add {{Csrf_field ()}} to prevent cross-site attacks when submitting data as a post, so it's natural to add the form when you use Ajax.

On the internet to see a lot of solutions, I use the following method to solve:

1, first add a meta in the template:

<meta name= "_token" content= "{{Csrf_token ()}}"/>

2, and then in the Ajax method add

Headers: {' X-csrf-token ': $ (' meta[name= ' _token "] '). attr (' content ')},

This is the Ajax method, found a very useful jquery function, $ (). Serialize () and $ (). Serializearray (), I use the latter in the code, can get the data in the form form, and can be transmitted directly through AJAX, it is AMAZING!!! (Ignorant let everyone laughed at)

$ (form[1]). Submit (Function (event) {    var data = $ (form[1]). Serializearray ();    Console.log (data);    $.ajax ({      type: ' Post ',      URL: '/basic ',      data:data,      headers: {  ' X-csrf-token ': $ (' meta[name= ' _ Token "]). attr (' content ')},      success:function (msg) {        if (msg) {          $ ('. Basicedit '). Hide ();          $ ('. Basicshow '). Show ();          $ ('. Basicshow span '). HTML (data[1].value+ ' | ' +data[2].value+ ' | ' +data[3].value+ ' | ' +data[4].value+ ' <br> ' +data[5].value+ ' | ' +data[6].value+ ' | ' +data[7].value}        ,}    );    Event.preventdefault ();    return false;  });

3 then get the data in the Controller method, just $req-> your form name is OK.

Public Function Basic (Request $req) {   //return $req->gender;   $uid = Auth::user ()->uid;   return $uid;   $inf = new \app\info;   $inf = Info::where (' uid ', $uid)->first ();   return $inf;   $inf->name = $req->name;   $inf->gender = $req->gender;   $inf->topdegre = $req->topdegre;   $inf->workyear = $req->workyear;   $inf->tel = $req->tel;   $inf->email = $req->email;   return $inf->save ()? " OK ":" Fail ";  }

Summary below:

I think every step I say must be!!!, my callback function is written in the code is to get the form inside the data re-printed out, do not need to ignore it, and then the code will see it, a PHP beginner to serve.
