Question

I have a table that displays the data from my database. at the end of each row I have an Edit/Update Button. I would like it when clicking on the edit button it reference the the Edit Form.

My edit form works. I can access the data when visiting computers/{id}/edit, The form displays the current data and I can edit the data and submit the updates and it updates in the database (mysql).

This is my index.blade.php, which displays the table with the update button

@extends('layout')


@section('content')
    <h1>Inventory</h1>

        <table class="table table-striped">
            <thead>
                <tr>
                    <th>Last Name</th>
                    <th>First Name</th>
                    <th>Department</th>
                    <th>Building</th>
                    <th>Room</th>
                    <th>Manufacturer</th>
                    <th>Device</th>
                    <th>Model</th>
                    <th>Service Tag</th>
                    <th>Mac Address</th>
                    <th>Status</th>
                    <th>Comments</th>


                </tr>
            </thead>

            <tbody>

                @foreach($inventories as $inventory)
                    <tr>
                    <td>{{$inventory->lastName}}</td>
                    <td>{{$inventory->firstName}}</td>
                    <td>{{$inventory->department}}</td>
                    <td>{{$inventory->building}}</td>
                    <td>{{$inventory->room}}</td>
                    <td>{{$inventory->manufacturer}}</td>
                    <td>{{$inventory->device}}</td>
                    <td>{{$inventory->model}}</td>
                    <td>{{$inventory->tag}}</td>
                    <td>{{$inventory->macAddress}}</td>
                    <td>{{$inventory->status}}</td>
                    <td>{{$inventory->comments}}</td>
                    <td>
                        {{--Need the button to open up my edit form--}}
                        <button formaction="computers/{id}/edit">{{ trans('computers.edit') }}</button>
                        {{--<input type="submit" name="update" id="update" value="Update" class="btn btn-primary">--}}
                    </td>
            </tr>
                @endforeach
            </tbody>
        </table>


@stop

This is my form.blade.php - which is a partial that I include in my create.blade.php and edit.blade.php and both of these pages work.

Answer 1

我不使用按钮而是使用<a>标签。

<a href="{{ url('computers/'.$inventory->id.'/edit') }}>{{ trans('computers.edit') }}</a>

url()函数是Laravel helper function

此外..我确信有足够的例子可以说明这一点，所以请务必先查看你的问题。

Answer 2

试试这个：

<button href="computers/{id}/edit">{{ trans('computers.edit') }}</button>

或者您可以使用表格（Laravel Collective方式）：

{!! Form::open(['method' => 'Get', 'route' => ['computers.edit', $inventory->id]]) !!}
{!! Form::submit(trans('computers.edit')) !!}
{!! Form::close() !!}

Answer 3

对不起，我晚答复

如果您要创建bigger project，并且不想在每个{p

write the code文件，用于生成index.balde.php按钮

只需使用我的助手功能

例如：

Laravel 5.7 打开您的模型，它可能是Edit,Show,Delete或Computer

只需将以下代码粘贴到其中

SomeModel

现在全部设置完毕，然后打开index.blade.php

并替换您的代码

public static  function tableActionButtons($fullUrl,$id,$titleValue,$buttonActions = ['show', 'edit', 'delete'],$buttonOptions='')
    {

            //Value of the post Method
            $postMethod = 'POST';
            //if the application is laravel then csrf is used
            if (function_exists('csrf_token'))
            {
              $token = csrf_token();    
            }elseif (!function_exists('csrf_token')) 
            //else if the mcrypt id is used if the function exits
                {
                    if (function_exists('mcrypt_create_iv')) 
                    {
                        // if the mcrypt_create_iv id is used if the function exits the set the token
                        $token = bin2hex(mcrypt_create_iv(32, MCRYPT_DEV_URANDOM));
                    }
                    else{
                        // elseopenssl_random_pseudo_bytes is used if the function exits the set the token
                        $token = bin2hex(openssl_random_pseudo_bytes(32));
                    }
                }        

            //action button Value 
            //(url()->full()) will pass the current browser url to the function[only aplicable in laravel]

                }

            }                       
        }

有了这个

<td>
     {{--Need the button to open up my edit form--}}
     <button formaction="computers/{id}/edit">{{ trans('computers.edit') }}</button>
     <input type="submit" name="update" id="update" value="Update" class="btn btn-primary">
</td>

如果您发现按钮中有任何错误或问题，请在以下部分中进行评论，以改善我的帮助脚本

非常注意，如果您现在{!! Computer::tableActionButtons(url()->full(),$inventory->id,$inventory->firstName,['edit',delete,delete],'dropdown'); !!}

，这是拉拉尔语EXPERTS
