Display Recipes Using App Inventor - app-inventor

I am using app inventor to build a recipe app. I was wondering how I could take the information from a user submitting stuff into this form I am very new to app inventor and so I don't think it's complete. I would like to take whatever the user will submit and display it on another screen. How could I do this? Please tell me where I am not clear.

There are many methods for a user to input data in App Inventor apps. A good example is a spinner.
According to the AI2 documentary, a spinner component that displays a pop-up with a list of elements. It looks like this.
Source: Pevest.com
The user can select an option. Once an option is selected, a spinner.AfterSelecting event triggers.
The orange section of the event controller holds a variable. The variable denotes the option the user chose. It updates automatically when a new option is chosen.
You may use the variable provided to send data the rest of the app. For example,
The set command sets recipeName to the option the user chose.
If you want to open another screen and send some information to it, use the startScreen with startValue function. It allows you to send custom text, which you can get on the other screen using the Get Start Value under Control blocks

How can I collect data in SwiftUI and show it to all users?

I'm using a SwiftUI, and I want to create a list of functionality that has not yet been added to my app and allow users to vote for the functionality they want to see first.
Basically, it will be a list of labels with buttons. When the user taps a button, it should show a number (how many users voted for it too).
As I understand, I need a DB where the data will be written and from where the data will be read and displayed in the app. Can I use a CloudKit for it?

In Slack, is it possible for an app to respond to a slash command by displaying a picker popup?

As example, let's say I wanted to write an app such that when the user types /movie in a channel, a list of popular movies is shown, the user selects one, and as a result a link to that movie in IMDB is inserted into the channel as text. Is something like that possible?
Many thanks.
That's possible! A slash command is the vessel for further interactivity. You can have your slash command trigger a modal (https://api.slack.com/surfaces/modals).Your modal would offer a list of options and once the user submits, your app will be notified with a view_submission payload. You can test modal payloads using the Block Kit Builder which includes options to list items.

How to use button to display filtered data from excel table in PowerApps?

I am a newbie in PowerApps, and I am trying to build an app where based on user click, user should be able to see filtered data.My test data looks like below.For this I have created 3 button in my gallery titled as "Available", "Out-of-service" and "In-use". So, let's say when user clicks on "Available" button, the app should display the user "Sys1" and "Sys2". Likewise, same is true for "Out-of-service" and "In-use" button. I have my datasource save as ExcelTable in Onedrive and I was able to successfully connect to the source.However, when I tried below code on my "Available" button nothing happened.I am not sure what is the issue ? [SEE BELOW UPDATE]
If there is good tutorial available for this task feel free to attached link with your response.
Code
Filter(Table1,Column2,"Available" in Column2)
Note: Property: OnSelect
Update:
After little bit of research I found that I need to have separate screen to display my filtered data. So I used Navigate() function to take me to new screen. On my screen2 I have below code
Code:
Filter(Table1, column2="Available")
Note: Property is set to "OnVisible". I also added FormViewer using Forms-> Display option. Then under Properties tab,I added column names using Edit fields.
Still Issue is not resolved!
It sounds like you have the Filter command in the wrong place. It should be in the "Items" property for the table, not in the Buttons' or in the Screen's properties. The Buttons should toggle a variable to the different Statuses you have.
The Items property of the table/gallery/etc that shows the data would look like this:
Filter(Table1, Column2=currentStatus)
The buttons would all have code that looks like this but with different statuses:
Set(currentStatus, "Available")
That way when you click the buttons, the value of currentStatus changes and will change the action of the filter.
Also, you can have the data visible on the second screen if you want but it's not strictly necessary. You can do what I described on a single screen.

Joomla handling multiple ajax forms on the same page

I'm using Joomla to develop a user profile management component with AJAX.
The goal is to allow the user to edit his own user information. There is a lot of information so instead of having one massive form, I decided to make "subforms" or sections. And for the whole thing to be user-friendly I want to send the forms and refresh the user information with AJAX.
Here's an example :
There are two sections, "Basic user info" which displays the first name, the last name and the age of the person and "Extended user info" which displays the occupation, the company and the skills of the person. Each section has an "edit" link (or button) which turns the content into a form (AJAX) allowing the user to modify the presented information. You can only edit one section's information at a time. When the user has finished modifying the data, he sends the form with a "send" link (or button) and the section gets back to simply displaying the information of the section (with the updates that were just made).
So I need to know what is the most efficient way to develop such a component. I thought of two approaches :
1) In the "tmpl" directory of the main component view we the following files :
default_basic.php (displays the basic user information),
default_basic_edit.php (displays the form which allows the user to edit the basic information)
default_extended.php (displays the extended user information),
default_extended_edit.php (displays the form which allows the user to edit the extended info)
default.php (loads each of the display subtemplates with calls to JView::loadTemplate($subtemplate))
When the user clicks on an edit link, an AJAX call is made to the following URI index.php?option=com_userinfo&view=userinfo&subview=basic_edit&format=ajax, which causes the view class to call $this->loadTemplate('basic_edit') after assigning the user information to it.
If the user clicks cancel the same process is used to load the 'basic' template again. And if the user modifies the information and clicks the send link, the form is sent and then the 'basic' template is loaded too.
2) There is only a "default.php" file in the "tmpl" directory which holds the edit version and the display version of each section. But all the edit versions are hidden at first. And when the user clicks on the edit link the display version of the section becomes hidden and the edit version is displayed (using display:none and display:block). Then, if the user clicks the cancel button we do the opposite. And if the user clicks the send button we send an AJAX request to update the data in the database and return the updated user info which will be loaded into the display version of the section. And we finally replace the edit version of the section with its display version.
I know there's a lot of text but in the end it goes down to choosing between refreshing full HTML blocks with AJAX, or just sending the updated info and modifying the content of hidden blocks and then make them appear. So what do you think is the most logical approach, knowing that we are in a Joomla 1.5 environment ? How would you procede ? (maybe there are other ways to create such a component ?)
(I tried both ways and I couldn't entirely make it work so I decided to ask to see if it is a matter of conception...)
Thank you for taking the time to read all the text.
My answer is: why even refresh parts when it can be done without it?
For example when we are talking about basic form elements like text fields and check/radio buttons I would prefer the following: on a successful save/send simply display a nice message like "Profile saved" for some seconds and the user is sure that the changes are save and sound.
In case I msissed somthing let me know.
I have tried both solutions and #2 is the only one that worked for me.

what is the best way to enter multiple child records in a web form

for example, we have a web form to let the user enter personal info such as address and phone number, then the user need to enter the spouse and dependents information. I usually use a gridview for this, but some users complain it is difficult to use. so what is the most user-friendly or conventional way to handle it?
thanks.
I usually use AJAX to do this. Usually a Button and/or programming triggered by an event to add form items.
For example:
Username:
Password:
(+) PHONE
.. then every time you add "+ PHONE" I would add a new set of text boxes for more phone numbers.
One option might be to have a more user-friendly form where the user fills in information for a single individual, and then an "add" button that takes the contents of the form and inserts it into the gridview where it can be reviewed while simultaneously clearing the rest of the form to allow another individual's info to be added.
