Live search in laravel using AJAX
提问by Przemek
I want users to be able to search and display results on any page.
我希望用户能够在任何页面上搜索和显示结果。
Search box is in navbar like this:
搜索框在导航栏中，如下所示：
<form action="/search" method="get" autocomplete="off" class="navbar-form navbar-left">
<div class="form-group">
<input type="text" class="form-control" id="search_text" onkeyup="search_data(this.value, 'result'); placeholder="Search"></div>
<div id="result">
@include('results')
</div>
</div>
</form>
JQuery/AJAX:
jQuery/AJAX：
function search_data(search_value) {
$.ajax({
url: '/searching/' + search_value,
method: 'GET'
}).done(function(response){
$('#results').html(response); // put the returning html in the 'results' div
});
}
Controller:
控制器：
public function search() {
$search_text = $_GET['text'];
if ($search_text==NULL) {
$data= Business::all();
} else {
$data=Business::where('name','LIKE', '%'.$search_text.'%')->get();
}
return view('results')->with('results',$data);
}
Route:
路线：
Route::post('/searching', 'SearchController@search');
Results.blade.php
结果.blade.php
<table style="width:100%">
<tr>
<th>Name</th>
<th>Logo</th>
</tr>
@foreach( $results as $business )
<tr>
<td>{{ $business->logo }}</td>
<td>{{ $business->name}}</td>
</tr>
@endforeach
</table>
This is what I have got so far and I am getting this error:
这是我到目前为止所得到的，我收到了这个错误：
Undefined variable: results
(View: C:\xampp\htdocs\laravel\resources\views\results.blade.php)
(View: C:\xampp\htdocs\laravel\resources\views\results.blade.php)
(View: C:\xampp\htdocs\laravel\resources\views\results.blade.php)
未定义变量：结果

Can anyone kindly please help a poor soul?
任何人都可以请帮助一个可怜的灵魂吗？

You are including the results view in the form blade, where the resultsvariable in the results view is not initially available. You could instead do a check in the results view to make sure to loop through the collection only if the data is available
您将结果视图包含在表单刀片中，结果视图中的results变量最初不可用。您可以改为在结果视图中进行检查，以确保仅在数据可用时循环遍历集合
<table style="width:100%">
<tr>
<th>Name</th>
<th>Logo</th>
</tr>
@if (isset($results) && count($results) > 0)
@foreach( $results as $business )
<tr>
<td>{{ $business->logo }}</td>
<td>{{ $business->name}}</td>
</tr>
@endforeach
@endif
</table>

You are using Route type postand ajax method as get. You need to change your ajax method
您正在使用 Route 类型post和 ajax 方法作为get. 你需要改变你的ajax方法
function search_data(search_value) {
$.ajax({
url: '/searching/' + search_value,
method: 'POST'
}).done(function(response){
$('#results').html(response); // put the returning html in the 'results' div
});
}
and access that search text in your Controller as
并在您的控制器中访问该搜索文本
public function search($search = null) {
$search_text = $search;
if ($search_text==NULL) {
$data= Business::all();
} else {
$data=Business::where('name','LIKE', '%'.$search_text.'%')->get();
}
return view('results')->with('results',$data);
}

I'm not entirely sure how ->with()works, but you can add data to your view helper directly with either of the two options:
我不完全确定->with()是如何工作的，但是您可以使用以下两个选项之一直接将数据添加到您的视图助手：
return view('results', ['results' => $data]);
Or
或者
return view('results', compact('data'));
Note that the last option will create a variable $data with the value of $data in your view.
请注意，最后一个选项将在您的视图中创建一个值为 $data 的变量 $data。
