Question

我有两个表“patient”和“booking”表，并且它们之间存在“一对多”关系，我想在index_booking页面中设置一个搜索表单，用户可以在其中键入patient_name并根据WHERE条件自动完成显示患者表中的所有患者名称。

这是预订模式

class Booking extends Eloquent
{

    public function patient()
    {
      return $this->belongsTo('App\Patient'); 
    }

    public function user()
    {
      return $this->belongsTo('App\User'); 

    }
}

这是患者模型

class Patient extends Eloquent
{
    public function booking()
    {
      return $this->hasMany('App\Booking'); 
    }

    public function user()
    {
      return $this->belongsTo('App\User'); 

    }
}

我在预订的索引页面中使用了这段代码

{!! Form::text('search_text', null, array('placeholder' => 'Search Text','class' => 'form-control','id'=>'search_text')) !!}

我在Booking Controller中使用此代码进行自动填充以显示数据来自病人表：

public function autoComplete(Request $request)
{
    $patients = Patient::where('company_id', Auth::user()->company_id)
        ->where('patient_name', 'like', "&{$request->get('term')}&")
        ->get();

    if ($patients->isEmpty()) {
        return ['value' => 'No Result Found', 'id' => ''];
    }

    return $patients->map(function ($patient) {
        return [
            'id'    => $patient->id,
            'value' => $patient->patient_name,
        ];
    });
}

这是路线

Route::get('autocomplete',array('as'=>'autocomplete','uses'=>'BookingController@index'));
Route::get('searchajax',array('as'=>'searchajax','uses'=>'BookingController@autoComplete'));

Javascript代码

<script >
$(document).ready(function() {
    src = "{{ route('searchajax') }}";
     $("#search_text").autocomplete({
        source: function(request, response) {
            $.ajax({
                url: src,
                dataType: "json",
                data: {
                    term : request.term
                },
                success: function(data) {
                    response(data);

                }
            });
        },
        minLength: 3,

    });
});

</script>

当我在搜索框中输入任何患者姓名时，我收到了一条未找到结果的消息

这是预约控制器中的验证器：

 public function store(Request $request)
    {
        //Validate Data
        $this->validate($request, [
              'patient_id'=> 'required|integer',             
               'booking_date'=> 'required|max:255',
               'tybe'=> 'required',
               'value'=>'required',
               'doctor_name',
               'patient_history',
               'pharma',
               'complaint',
               'diagnosis',
               'recomind',
               'prescription',
               'notes',
               'document',
               'by',



            ]);  

               //Insert Data to Database
               $booking = new Booking;

               $booking->patient_id = $request->patient_id;
               $booking->booking_date = $request->booking_date;
               $booking->tybe  = $request->tybe;
               $booking->value = $request->value;
               $booking->doctor_name = $request->doctor_name;
               $booking->patient_history = $request->patient_history;
               $booking->pharma = $request->pharma;
               $booking->complaint = $request->complaint;
               $booking->diagnosis = $request->diagnosis;
               $booking->recomind = $request->recomind;
               $booking->prescription = $request->prescription;
               $booking->notes = $request->notes;
               $booking->document = $request->document;
               $booking->by = $request->by;

               $booking->save();



               //to save multi selection Tags ,dont foget to add [] after -> tags in create post page then write this code here
               //$post->tags()->sync($request->tags, false);

               //Show Flash Message

                Session::flash('success','تم حفظ البياانات');

               //Redirect to another Page 

               return redirect()->route('booking.index');
    }

Answer 1

SQL与LIKE运算符匹配的语法是：

WHERE `column` LIKE '%needle%'

另一方面，您的代码产生以下内容：

WHERE `column` LIKE '&needle&'

这与您输入的内容几乎相同：

WHERE `column` = '&needle&'

因此，您需要做的是将&替换为以下行中的%：

->where('patient_name', 'like', "&{$request->get('term')}&")

自动完成在laravel中找不到结果
