Flask sends form data to the template

We have seen that the http method can be specified in the URL rules. The Form data received by the trigger function can be collected in the form of a dictionary object and forwarded to the template to present it on the corresponding web page.

In the following example, the '/' URL will render a web page with a form (student.html). The filled data will be published to the '/result' URL that triggers the result() function .

The results() function collects the form data existing in request.form in the dictionary object and sends it to result.html .

This template dynamically renders an HTML table of form data.

Given below is the Python code of the application:

from flask import Flask, render_template, request

app = Flask(__name__)

@app.route('/')
def student():
    return render_template('student.html')


@app.route('/result', methods=['POST', 'GET'])
def result():
    if request.method == 'POST':
        result = request.form
        return render_template("result.html", result=result)

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

Given below is the HTML script of student.html .

 <form action="http://localhost:5000/result&quot" method="POST">
     <p>Name <input type = "text" name = "Name" /></p>
     <p>Physics <input type = "text" name = "Physics" /></p>
     <p>Chemistry <input type = "text" name = "chemistry" /></p>
     <p>Maths <input type ="text" name = "Mathematics" /></p>
     <p><input type = "submit" value = "submit" /></p>
  </form>

The code for the template (result.html) is given below :

< > and other escape characters, please refer to https://blog.csdn.net/u013066730/article/details/108358895

It was found that the escape character was not good, so it was unnecessary.

<!doctype html>
<html>
   <body>
   
      <table border = 1>
         {% for key, value in result.items() %}
         
            <tr>
               <th> {
   
   { key }} </th>
               <td> {
   
   { value }} </td>
            </tr>
            
         {% endfor %}
      </table>
      
   </body>
</html>

Run the Python script and enter the URL http://localhost:5000/ in the browser .

When the submit button is clicked, the form data is presented on result.html in the form of an HTML table .
