如何使用 Flask 在 MYSQL 中插入复选框值答案

【问题标题】：How to insert check box value in MYSQL using Flask如何使用 Flask 在 MYSQL 中插入复选框值
【发布时间】：2021-06-15 13:08:23
【问题描述】：

我在 HTML 中有三个复选框，我在 Python 中获得了复选框值。如果我选择复选框，则表示该值应在 MYSQL 数据库中插入为“是”，否则应插入为“否”。我试过但我不知道如何获得答案。请帮助我，在此先感谢:)

这是我的代码： HTML：

<form action='/hello' method="POST" enctype="multipart/form-data">
Panchayath <input type="checkbox" name="checks[]" value="yes" id="panchayath"><br>
     Ward  <input type="checkbox" name="check[]" value=" yes" id=" ward"><br>
    Results  <input type="checkbox" name="chec[]" value=" yes" id=" results">
    <input type="submit" value="Submit">
</form>

py:

import os
from flask import Flask, request, render_template
from flaskext.mysql import MySQL

mysql = MySQL()

app = Flask(__name__)
app.config['MYSQL_DATABASE_USER'] = 'root'
app.config['MYSQL_DATABASE_PASSWORD'] = 'root'
app.config['MYSQL_DATABASE_DB'] = 'bucketlist'
app.config['MYSQL_DATABASE_HOST'] = 'localhost'
mysql.init_app(app)
APP_ROOT = os.path.dirname(os.path.abspath(__file__))


@app.route('/hello', methods=['GET', 'POST'])
def get_data():
    print("hlo")
    if request.method == 'POST':
        print("cat")
        panchayath = request.form.getlist('checks[]')
        print panchayath
        ward = request.form.getlist('check[]')
        print ward
        Results = request.form.getlist('chec[]')
        print Results
        conn = mysql.connect()
        cursor = conn.cursor()
        # cursor.execute()
        print "yes"
        # cursor.execute("insert into try_chk3  values (%s,%s,%s)", (some_var))
        # query = "CREATE TABLE saracheck( panchayath  VARCHAR(40), ward VARCHAR(40),Results VARCHAR (40))"
        # cursor.execute(query)
        query = "INSERT INTO saracheck(panchayath,ward,Results) VALUES(%s,%s,%s)"
        a=cursor.execute(query, (panchayath,ward,Results))
        print a
        print "execuet"
        # cursor.execute(query,(first_name,last_name,email_id,can_pic,logo_pic))
        conn.commit()


    return render_template("form.html")


if __name__ == '__main__':
    app.run()

输出： enter image description here

【解决方案1】：

首先，您为什么要命名“checks”、“check”和“chec”之类的字段，它们要么看起来都是 name = "checks[]"，要么只是命名方式不佳。

您不是要获取所有三个字段的值吗？那么你应该尝试得到他们三个中的Results 对吗？

您能否也发布到目前为止您得到的输出？

我是python新手，如果选中，我想在数据库中插入复选框值？
我在上面发布了我的输出页面

【解决方案2】：

 <label for="">Amenities Required</label><br>
 <input type="checkbox" name="users" value="Bike" checked> I have a bike<br>
 <input type="checkbox" name="users" value="Car"> I have a car<br>
 <input type="checkbox" name="users" value="Boat" > I have a boat<br>
 <input type="checkbox" name="users" value="cycle"> I have a cycle<br>
 <input type="checkbox" name="users" value="wagnor"> I have a wagnor<br>
 <input type="checkbox" name="users" value="safari" > I have a safari<br>

      if request.method=='POST':
      amin=request.form.getlist("users")
      str1 = ','.join(amin)
      c.execute("INSERT INTO tablename VALUES(%s)",[str1])
