Flask Python Buttons
PythonHtmlButtonFlaskPython Problem Overview
I'm trying to create two buttons on a page. Each one I would like to carry out a different Python script on the server. So far I have only managed to get/collect one button using.
def contact():
form = ContactForm()
if request.method == 'POST':
return 'Form posted.'
elif request.method == 'GET':
return render_template('contact.html', form=form)
What would I need to change based on button pressed?
Python Solutions
Solution 1 - Python
Give your two buttons the same name and different values:
<input type="submit" name="submit_button" value="Do Something">
<input type="submit" name="submit_button" value="Do Something Else">
Then in your Flask view function you can tell which button was used to submit the form:
def contact():
if request.method == 'POST':
if request.form['submit_button'] == 'Do Something':
pass # do something
elif request.form['submit_button'] == 'Do Something Else':
pass # do something else
else:
pass # unknown
elif request.method == 'GET':
return render_template('contact.html', form=form)
Solution 2 - Python
The appropriate way for doing this:
@app.route('/')
def index():
if form.validate_on_submit():
if 'download' in request.form:
pass # do something
elif 'watch' in request.form:
pass # do something else
Put watch and download buttons into your template:
<input type="submit" name="download" value="Download">
<input type="submit" name="watch" value="Watch">
Solution 3 - Python
In case anyone was still looking and came across this SO post like I did.
<form>
<input type="submit" name="open" value="Open">
<input type="submit" name="close" value="Close">
</form>
def contact():
if "open" in request.form:
pass
elif "close" in request.form:
pass
return render_template('contact.html')
Simple, concise, and it works. Don't even need to instantiate a form object.
Solution 4 - Python
I handle it in the following way:
<html>
<body>
<form method="post" action="/">
<input type="submit" value="Encrypt" name="Encrypt"/>
<input type="submit" value="Decrypt" name="Decrypt" />
</form>
</body>
</html>
Python Code :
from flask import Flask, render_template, request
app = Flask(__name__)
@app.route("/", methods=['GET', 'POST'])
def index():
print(request.method)
if request.method == 'POST':
if request.form.get('Encrypt') == 'Encrypt':
# pass
print("Encrypted")
elif request.form.get('Decrypt') == 'Decrypt':
# pass # do something else
print("Decrypted")
else:
# pass # unknown
return render_template("index.html")
elif request.method == 'GET':
# return render_template("index.html")
print("No Post Back Call")
return render_template("index.html")
if __name__ == '__main__':
app.run()
Solution 5 - Python
I think this solution is good:
@app.route('/contact', methods=['GET', 'POST'])
def contact():
form = ContactForm()
if form.validate_on_submit():
if form.submit.data:
pass
elif form.submit2.data:
pass
return render_template('contact.html', form=form)
Form:
class ContactForm(FlaskForm):
submit = SubmitField('Do this')
submit2 = SubmitField('Do that')
Solution 6 - Python
Apply (different) name attribute to both buttons like
<button name="one">
and catch them in request.data.
Solution 7 - Python
this work to me .py
if request.method == "POST":
if request.form.get('new Token'):
#something
if request.form.get('custom Token'):
#something diferent
.html
<form method="post" >
<input type="submit" name="new Token" value="new Token">
<input type="submit" name="custom Token" value="custom Token">
</form>
works because the button that you do not oppress ,return None to python. nice day
