Linking edit button from table to Laravel Edit form
提问by Afonte
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.
我有一个表格显示我的数据库中的数据。在每一行的末尾我有一个编辑/更新按钮。当单击编辑按钮时，我希望它引用编辑表单。
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).
我的编辑表单有效。我在访问computers/{id}/edit时可以访问数据，表单显示当前数据，我可以编辑数据并提交更新，它在数据库（mysql）中更新。
This is my index.blade.php, which displays the table with the update button
这是我的 index.blade.php，它显示带有更新按钮的表格
@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>

@endforeach

@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.
这是我的 form.blade.php - 这是我包含在我的 create.blade.php 和 edit.blade.php 中的一个部分，这两个页面都可以工作。

Try this:
尝试这个：
<button href="computers/{id}/edit">{{ trans('computers.edit') }}</button>
Or you could use form (Laravel Collective way):
或者您可以使用表单（Laravel 集体方式）：
{!! Form::open(['method' => 'Get', 'route' => ['computers.edit', $inventory->id]]) !!}
{!! Form::submit(trans('computers.edit')) !!}
{!! Form::close() !!}
回答by Rick
Instead of using a button I would use an <a>tag.
我会使用<a>标签而不是使用按钮。
<a href="{{ url('computers/'.$inventory->id.'/edit') }}>{{ trans('computers.edit') }}</a>
the url()function is a Laravel helper function
该url()函数是一个Laravel 辅助函数
Also.. I'm sure there are enough examples of things like this, so make sure you google your question first.
另外..我相信有足够多的这样的例子，所以一定要先用谷歌搜索你的问题。

index.balde.phpfile for generarting the Edit,Show,DeleteButtons
index.balde.php用于生成Edit,Show,Delete按钮的文件
just use my helper function
只需使用我的辅助功能
For Eg:
例如：
Laravel 5.7
Open Your Model it may be Computeror SomeModel
Laravel 5.7 打开你的模型它可能是Computer或SomeModel
Just Paste the following Code into it
只需将以下代码粘贴到其中
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]
$urlWithId =$fullUrl.'/'.$id;
//Charset UsedByFrom
$charset = 'UTF-8';
// Start Delete Button Arguments

'.$actionButtons.'
</div>
</div>
';
return $dropDownButton;
}else

}
Now all are set then open your index.blade.php
现在一切都设置好了然后打开你的 index.blade.php
and replace your code
并替换您的代码
<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>
With This
有了这个
{!! Computer::tableActionButtons(url()->full(),$inventory->id,$inventory->firstName,['edit',delete,delete],'dropdown'); !!}
