# Usage for validate email from form

*Note: WTForms and Flask-WTF must be installed before using this features.*

This Flask Python module had three different validator for different uses: EmailValidation for validating email address by all parameters, DisposableEmailValidation for validating disposable email address, and FreeEmailValidation for validating free email address.

1. Import the validator class from the package. For example: `from flask_MailboxValidator.SingleValidation import EmailValidation`

2. Call the validator in validator array along with your API key. For example: `email = StringField('Email:', validators=[validators.InputRequired(), EmailValidation(apikey='Your_API_Key')])`

Sample Codes

============

## Validate email

```python

import flask_MailboxValidator

from flask import Flask

from flask import jsonify

app = Flask(__name__)

mbv = flask_MailboxValidator.SingleValidation('PASTE_API_KEY_HERE')

results = mbv.ValidateEmail('[email protected]')

@app.route('/')

def display_result():

	if results is None:

		return("Error connecting to API.\n")

	elif 'error' not in results:

		return (jsonify(results))

	else:

		return('error_message = ' + results['error']['error_message'] + "\n")

```

Check if an email is from a disposable email provider

-------------------------------------------------------------------

```python

import flask_MailboxValidator

from flask import Flask

from flask import jsonify

app = Flask(__name__)

mbv = flask_MailboxValidator.SingleValidation('PASTE_API_KEY_HERE')

results = mbv.DisposableEmail('[email protected]')

@app.route('/')

def display_result():

	if results is None:

		return("Error connecting to API.\n")

	elif 'error' not in results:

		return (jsonify(results))

	else:

		return('error_message = ' + results['error']['error_message'] + "\n")

```

Check if an email is from a free email provider

------------------------------------------------------------

```python

import flask_MailboxValidator

from flask import Flask

from flask import jsonify

app = Flask(__name__)

mbv = flask_MailboxValidator.SingleValidation('PASTE_API_KEY_HERE')

results = mbv.FreeEmail('[email protected]')

@app.route('/')

def display_result():

	if results is None:

		return("Error connecting to API.\n")

	elif 'error' not in results:

		return (jsonify(results))

	else:

		return('error_message = ' + results['error']['error_message'] + "\n")

```
