Unable to fetch data in request.form in flask - html

Question

I am using flask as the backend and i have my html template as
<div id="tablediv">
<form action="{{ url_for('useraction') }}" method="post">
<table class="table" id="displaytable">
<thead>
<tr>
<th scope="col">Name</th>
<th scope="col">Email</th>
<th scope="col">Address</th>
<th scope="col">Action</th>
</tr>
</thead>
<tbody>
{%for i in range(0, len)%}
<tr>
<td id="username" name = "username">{{unverifieduser[i][1]}}</td>
<td id="useremail" name="useremail">{{unverifieduser[i][2]}}</td>
<td id="useraddress" name="useraddress">{{unverifieduser[i][3]}}</td>
<td >
<button type="submit" class="btn btn-danger" id="delete" name="delete">Delete</button>
<button type="submit" class="btn btn-warning" id="verify" name="verify">Verify</button>
</td>
</tr>
{%endfor%}
</tbody>
</table>
</form>
</div>
My API call looks like
#app.route('/useraction', methods = ['GET', 'POST'])
def useraction():
print(request.form)
if request.method =='POST':
cursor = mysql.connection.cursor()
cursor.execute('SELECT * FROM user where isVerified = false');
user = cursor.fetchall()
return render_template('user.html', len = len(user), unverifieduser = user)
The output gives only the button which i click for example 'verify'
enter image description here
Is there any html attribute I am missing to get all the elements of the table for example username, useremail, useraddress

Answer 1

An HTML table or HTML table elements are not Form elements. In HTML, only Form elements are sent along with such a POST request. Here is an overview of all HTML Form elements. Note that these elements should be inside a form element, which is in your case the following line:
<form action="{{ url_for('useraction') }}" method="post">
As for why you only have verify in your form: the sole other input element in your form is the delete button, with its type set to submit. While you can have multiple submit buttons, only the one you click is sent along with the form.
