app.py is a server written in flask

#details
@app.route('/details', methods = ['GET','POST'])
def details():
    if not(c_id == 0) and request.method == "POST":
        data = request.form
        #Name = data['fname']
        Email = data['email']
        Phone = data['phonenumber']
        Altphone = data['Altphonenumber']

        cur = mysql.connection.cursor()
        cur.execute("INSERT INTO details(name,email,phone,alt_phone,address) VALUES (%s,%s,%s,%s,%s)", (Name,Email,Phone,Altphone,Address))

        mysql.connection.commit()
        cur.close()
        return render_template('creditcarddetails.html')
    else:
        return redirect(url_for('login'))
    return render_template('details.html')

【问题讨论】：

我认为只有当电子邮件不在 request.form 中时才会出现此键错误？您的代码在这里运行良好。

【解决方案1】：

首先，你需要在 `form` 中提及 `action` 属性。在您的情况下，它将是 `action="{{ url_for('details') }}"`
而不是将其存储在 request.form 中的 data 变量中，您可以直接以这种方式放置它：
`Email = request.form['email']`
