Question

我正在Laravel 5.4中的网站上工作，在该网站中我不确定如何从表单中提取复选框信息。

从我使用复选框信息的fiddle复制的HTML代码是：

<div class ="form_check_attachments mt-4 ml-2">
   <div class="form-group  disney_posting_formchecks">
      <div class="form-check mb-3">
         <input class="form-check-input" type="checkbox" id="gridCheck">
         <label class="form-check-label" for="gridCheck">
         im interested in setting up a <span style="color:rgb(67, 67, 67);font-weight:bold;">pro</span>Store
         </label>
      </div>
      <div class="form-check mb-3">
         <input class="form-check-input" type="checkbox" id="gridCheck">
         <label class="form-check-label">
         I just want to post a thing or two on disney
         </label>
      </div>
      <div class="form-check mb-3">
         <input class="form-check-input" type="checkbox" id="gridCheck">
         <label class="form-check-label">
         I wanted to be notified when the app is live
         </label>
      </div>
   </div>
</div>

我正在使用的控制器代码是：

   public function store(Request $request)
   {

/*
    dd($request->all());

  */   
      $this->validate($request, [
      'name' => 'required',
      'email' => 'required|email',
      'number' => 'required',
      'city' => 'required',
      'post' => 'required'
      ]);

      Mail::send('emails.posting-message', [
        'msg'=> "Name\t" . $request->name . "\r\n"
        . "Email\t" . $request->email . "\r\n"
        . "Number\t" . $request->number . "\r\n"
        . "City\t" . $request->city . "\r\n"
        . "Message\t" . $request->post . "\r\n"


       ], function($mail) use($request) {

          $mail->from($request->email, $request->name);

           $mail->to('jamalferhan@gmail.com')->subject('Contact Message');
       });

       return redirect()->back()->with('flash_message', 'thank you, your posting info has been sent to our team. we will reach out as soon as we can to provide next steps!');

   }

问题陈述：

我想知道我需要在控制器中进行哪些更改，以便能够提取所有复选框信息。目前，它仅从输入字段中提取值。

Answer 1

根据我在代码中看到的内容，只需将 name属性添加到输入type =“ checkbox”（复选框）中，以便可以看到它们在请求中传递。 / p>

from imutils.video import VideoStream
from imutils import face_utils
import datetime
import argparse
import imutils
import time
import dlib
import cv2
import numpy as np

# path to facial landmark predictor
ap = argparse.ArgumentParser()
ap.add_argument("-p", "--shape-predictor", required=True)

print("[INFO] loading facial landmark predictor...")
detector = dlib.get_frontal_face_detector()
predictor = dlib.shape_predictor(args["shape_predictor"])

# grab the indexes of the facial landmarks
(lebStart, lebEnd) = face_utils.FACIAL_LANDMARKS_IDXS["left_eyebrow"]
(rebStart, rebEnd) = face_utils.FACIAL_LANDMARKS_IDXS["right_eyebrow"]
(jawStart, jawEnd) = face_utils.FACIAL_LANDMARKS_IDXS["jaw"]

# initialize the video stream and allow the cammera sensor to warmup
print("[INFO] camera sensor warming up...")
vs = VideoStream(usePiCamera=args["picamera"] > 0).start()
time.sleep(2.0)

# loop over the frames from the video stream
while True:
    # grab the frame from the threaded video stream, resize it to
    # have a maximum width of 400 pixels, and convert it to
    # grayscale
    frame = vs.read()
    frame = imutils.resize(frame, width=400)
    gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)

    # detect faces in the grayscale frame
    rects = detector(gray, 0)

    # loop over the face detections
    for rect in rects:
        shape = predictor(gray, rect)
        shape = face_utils.shape_to_np(shape)

        # extract the face coordinates, then use the
        faceline = shape[jawStart:lebEnd]

        # compute the convex hull for face, then
        # visualize each of the face
        facelineHull = cv2.convexHull(faceline)

        mask = np.zeros(frame.shape,dtype='uint8')
        cv2.drawContours(frame, [facelineHull], -1, (0, 0, 0),thickness=cv2.FILLED)
        cv2.drawContours(frame, [facelineHull], -1, (0, 255, 0))

    # show the frame
    cv2.imshow("Frame", frame)
    # cv2.imshow("Frame", mask)
    key = cv2.waitKey(1) & 0xFF

    # if the `q` key was pressed, break from the loop
    if key == ord("q"):
        break


# do a bit of cleanup
cv2.destroyAllWindows()
vs.stop()

在控制器中

<label class="checkbox-inline">
    <input type="checkbox" name="hello" value="hello">Hello
</label>
