Get the value of a checkbox in Flask

Question

I want to get the value of a checkbox in Flask. I\'ve read a similar post and tried to use the output of request.form.getlist(\'match\') and since it\'s a list

Answer 1

I found 4 ways to do that: Just to summarize:

# first way
op1 = request.form.getlist('opcao1') # [u'Item 1'] []
op2 = request.form.getlist('opcao2') # [u'Item 2'] []
op3 = request.form.getlist('opcao3') # [u'Item 3'] []

# second
op1_checked = request.form.get("opcao1") != None
op2_checked = request.form.get("opcao2") != None
op3_checked = request.form.get("opcao3") != None

# third
if request.form.get("opcao3"):
    op1_checked = True

# fourth
op1_checked, op1_checked, op1_checked = False, False, False
if request.form.get("opcao1"):
    op1_checked = True
if request.form.get("opcao2"):
    op2_checked = True
if request.form.get("opcao3"):
    op3_checked = True

# last way that I found ..
op1_checked = "opcao1" in request.form
op2_checked = "opcao2" in request.form
op3_checked = "opcao3" in request.form
