How to Submit HTML Form Data to a Flask Python Script?

Submitting User Input from HTML Form to a Python Script in Flask

To pass user input from an HTML form to a Python script in Flask, the form and its elements must be configured appropriately.

HTML Form Configuration:

• Set an action attribute on the
  tag that specifies the URL of the Python script that will handle the submitted data.
• Set the method attribute to "post" to submit the data as form data using the POST method.
• Include an enctype attribute with the value "multipart/form-data" if the form contains any file inputs.
• Give each input element a unique name attribute.

Python Script Configuration:

Define a view in the Python script to handle the submitted data with appropriate parameters for the input element's name. For example, the following view handles the "projectFilepath" input:

@app.route('/handle_data', methods=['POST'])
def handle_data():
    projectpath = request.form['projectFilepath']
    # ... Your code to process the input

Example HTML Form:

<form action="{{ url_for('handle_data') }}" method="post" enctype="multipart/form-data">
    <input type="text" name="projectFilepath" placeholder="Spot your project files">
    <input type="submit" value="Spot">
</form>

Additional Considerations:

• The url_for function generates the URL for the designated view dynamically based on the Flask application's route configuration.
• The Python script will have access to the submitted data from the input elements through the request.form or request.files objects, depending on the type of input.
