Issue with st.empty()

[Harish_Kodarapu]

Hello all,

I am facing a special issue as shown in the recording. The following is what I require in steps.

1. Select an option from the selectbar
2. Login with the credentials
3. On successful login, the login and password text_inputs should be vanished and file_uploader should arise.
4. After this a text_input for number of layers should be present.

The problem is as follows.
The moment I enter the input and press enter, the text_input vanishes and previously hidden login text_inputs are again shown.

Please let me know if you have any solution for this. Thanks in advance.

Hey @Harish_Kodarapu,

We actually cant see your screen recording, as you can’t post screen recordings on the forum. I imagine your having an issue with the statefulness of your app based on your description. Because the text_input fields do not preserve the users selection after multiple clicks/interactions on the page, when you hit enter on the second text_input it resets the app and it runs the script from top to bottom again.

We are currently creating a session state for streamlit to combat this very thing. IN the mean time there are some workarounds:

Multi-page app with session state

Hello there For a project I needed to build multi-page app with a settings page. As I’ve seen this topic requesting the feature, I decided to share the solution I came up with. It features a custom version of @thiago’s SessionState. It still relies on hacks, but it should work in most cases. It was tested with Streamlit version 0.61.0 (and now 0.65). Things you must be aware of before using it: You must call state.sync() at the end of your app if you set a widget’s default value to …

Programmable State for Streamlit

Hey Community , In a lot of ways getting a Streamlit app to store internal state, like information a user entered in a form, is simply too tricky. We’ve created some workarounds for session state, but we want to give you a baked-in, elegant version of programmable state so you can build apps with intricate sequential logic, such as multi-page apps. We’d like to use this topic as a central location for your ideas: What use cases would you like supported? How would you expect that use ca…

Programmable State Survey!

Hello Streamlit Community! My name is Abhi and I have recently joined Streamlit as a Product Manager. One of my first projects at Streamlit is to start working on Programmable State. Previously, Thiago has also posted about Programmable State here: Programmable State for Streamlit and the community feedback has been super helpful! We have started scoping the work and building prototypes. We are looking to interview users as well as sign up users for a closed beta program for Programmable State…

Happy Streamlit-ing!
