Menu
I'm new to using Flask and I've just been trying to pass a variable between two web pages. The first is a simple form to accept a number with the second page just displaying what is entered.
HTML for the form page:
<!doctype html>
<html>
<body>
<form action ="{{ url_for('return_form', glon="glon") }}" method="post">
Galactic Longitude: <input type="text" name="glon">
<button type="submit">Submit</button>
</form>
</body>
</html>
HTML for the display page:
<!doctype html>
<body>
<p> {{ glon }} </p>
</body>
</html>
The Flask script currently looks like this:
from flask import Flask
from flask import render_template, url_for, request, redirect
app = Flask(__name__)
@app.route('/')
def index():
return render_template('index.html')
@app.route('/form/', methods = ['GET', 'POST'])
def form():
if request.method == 'POST':
glon = request.form['glon']
#glat = request.form['glat']
return redirect(url_for('return_form', glon=glon))
return render_template('form.html')
@app.route('/return_form/<glon>', methods = ['GET', 'POST'])
def return_form(glon):
return render_template('return_form.html', glon=glon)
if __name__ == '__main__':
app.run()
At the moment, the second page just displays "glon" instead of the number passed to the form.
I simply want the variable to display on the second page, and eventually use it in the return_form function.

So i didn't got your approach.Below is what i did,I changed the code a bit. Hope this solves your problem.
main.py
from flask import Flask
from flask import render_template, url_for, request, redirect
app = Flask(__name__)
@app.route('/')
def index():
return render_template('index.html')
@app.route('/form', methods = ['GET', 'POST'])
def form():
if request.method == 'POST':
glon = request.form['glon']
return render_template('display.html', glon=glon)
# @app.route('/return_form/<glon>', methods = ['GET', 'POST'])
# def return_form(glon):
# return render_template('return_form.html', glon=glon)
if __name__ == '__main__':
app.run()
index.html
<html>
<body>
<form action ="{{ url_for('form') }}" method="post">
Galactic Longitude: <input type="text" name="glon">
<button type="submit">Submit</button>
</form>
</body>
</html>
display.html
<!doctype html>
<body>
<p> {{ glon }} </p>
</body>
</html>
