Dynamically disabling menu based on database query? - database

So I'm not a programmer, but my friend is. He's trying to help me develop a web/phone app but we are stuck because I'm having trouble communicating to him an idea and he is having trouble understanding. One or both of us is a moron ;) Part of the problem is that I don't even know where to search for the answer cuz I don't know the specific search terms...believe me I've tried...and I've searched stack overflow as well. Here is the problem:
Short Question:
Websites (like hotel search) allow you to search for rooms by selecting checkboxes in certain categories (i.e. smoking/nonsmoking, stars, size of bed, near downtown, etc.). Certainly these sites are referencing a large database of hotels in a city.
How can you create a site so that as you check boxes (narrow your search), other options which are no longer available are dynamically "grayed out" or disabled on the fly so you cannot check those boxes. So if I were to check 4 stars and that excluded all smoking rooms based on the database, then the option to check "smoking" would be disabled.
The key to this is that the site is querying a database as you click boxes, then based on the results of that query (which is presumably many rows of data (a subset)), it is analysing that subset of data to determine whether checkbox options should be on/off, then dynamically "graying out" specific options that are no longer available. Once you got to only a single possible result, then the site would pop up the website for that hotel (or some other action).
What is this called? Where can I get more information on this. Any pointing toward the right direction would be tremendously appreciated.
Thanks so much in advance!

HERE IS AN EDIT TO ORIGINAL QUESTION...HERE IS AN EXAMPLE:
So here is my sample database. Each Column (i.e. AA, AB, AC) represents a checkbox. '1'= True, '0'= False, and '2'= Either. Therefore, if you click checkbox AA, then only the top three rows would meet the criteria of AA=True. So query would return the top three rows. The '2's could be either True/False so since they don't affect outcome, those checkboxes should be disabled and only the checkboxes CA,CB, & CC should remain choosable. If you then click checkbox CB, then result ZYX would be output.
Conceptually, How do you go from the initial click to the point where the database is queried and the results are used to dynamically change the menu. People have suggested javascript but i am not looking for a language. I am more looking for the concept. I was thinking that the query would return a new "temp" array with just the top three rows. Then each column of this "temp" array would be queried to see if it contained a '1' in any of the rows. If it did, then that button would be turned "ON". If it didn't then that button would be turned "OFF". Is this confusing? Am I asking for too much ;)

This sounds like javascript could help. For example, using jQuery, you can dynamically send queries to databases based on whatever you click on checkboxes, and then reload a particular section of the webpage. Javascript can also dynamically disable checkboxes.

How can I sort and map my SQL query in Ionic?

I have a database running in the background, the aim of the whole thing should be that I have categories as buttons and that categories should be created under elements. I separated the whole thing in the database (i.e. in two tables), i.e. in categories and in the sub-elements. I get everything correctly selected but just don't know how to assign or build it. Does anyone have any ideas or examples to look at?
I've already tried Ionic's list system. Just like ion-record.

How can I make a photograph database that displays the results of a query as some kind of image gallery?

I am taking a database design class and for a project want to make a database of my mom's digital photos for her. I haven't dealt in application up to this point, only theory, but I have Access. Therefore, ideal answers don't suggest non-database solutions and don't assume I know much about actual database implementation. Solutions specific to Access could also be a plus. I hope that precursor saves some time and effort.
Theoretically, my mom wants to see all photos of pets from '05-'07 in raw format, and she enters an appropriate query. I suspect I can handle it up to there. However, at the moment, the best I can figure out to do is to return a column of either attachments or OLE objects. 5 clicks per photo is not ideal. I need a faster way to present the images. Opening them all in a grid of thumbnails or as a one-click-slide-show would seem the natural fit, but whatever works. How can I accomplish this?
Less important but worth consideration is the fact that, at some point, it would be great if this same type of system could be implemented on the internet for all of the family reunion photos she has taken, but I will take what I can get.
Use one form to get parameters for the query. then use another form(more processing) or report(if printing) to show the selected pictures. I will not cover passing parameters but here are some links.

https://learn.microsoft.com/en-us/office/vba/access/concepts/forms-design/apply-a-filter-when-opening-a-form-or-report
There is a complication, in Access pictures are usually stored in the attachment type. the attachment column can hold many pictures in each record. So if we have a table called Pictures with an attachment type column also called Pictures, then each individual picture is actually stored under Pictures.Pictures.FileData.
So to display the picture query we use a form/report with default view set to Continuous Forms (displays many records or in this case pictures on the same page) then in the details section of our Display form we place an attachment control and bind that control to our filtered Pictures.FileData.
Format and add functionality to taste.

How to show variable's value in Dialog Name (Einstein Bot)

I need to show the Product's Name in the Menu, I think image says it all:
Click here to see the image
I have a menu, with two options, and the first show a text with a variable, but {!Product} don't works, there is a way of this work?
When I put {!Product} in Message or Question, this works normal...
I didn't find any solution for showing the variable in the title dialog, my solution was to change the message to "Know more about this product", I left a generic message.
Old topic but the answer might help someone.
There's a great article explaining how to get some dynamic information https://www.infallibletechie.com/2021/11/how-to-create-case-from-einstein-bot.html
In your case, I guess you need to
Query your products (the out-of-the-box Einstein Bot query is simple and has a limit of 3 items but you could call a flow or apex to get better granularity on the filter/logic and control le size)
Store the query result in a Custom record list Variable
Query data with a flow
Use a dynamic question and merge fields to display what you want

Show Opportunity related Contacts in Custom Object Field

I have the next issue.
I have a custom object called 'Application', and I have this requirement:
"Show all Contacts related to an Application. Create a field on Application object, must be read only".
I solve it with apex code. 'Application' has a lookup to Opportunity, Opportunity to Account, and all my contacts have AccountId, so this way, I get all the contacts using apex code in a trigger.
But, I've been ask to change this to a Formula field in Application object.
So, my issue is next. I'm not able to get all contacts with advance formula editor, because they're not part of any object. I have no master-detail relationship.
Does any one know how can I achieve this using configuration? I should not use apex code for this req.
Thank in advance guys.
I don't think you can do it.
In formulas / merge fields syntax there's no way to go "up, up then down" (Application -> Opportunity -> Account -> down to Contacts related list). There's also nothing that would let you loop through Contacts (and display what? Ids? Names? Emails?). Roughly speaking you can only go up through dots.
You might want to explore path of "cross object workflow" rules but I imagine that when I add a new Contact to Account it should somehow "spread itself" to all related Applications? There's no straight way to fire a workflow on delete too - so you'd eventually end up with inaccurate list.
I'd say trigger was a good solution. Maybe it ws unoptimized but if it has to be in a field - tough.
There might be a fairly simple way of achieving that by embedding a visualforce page within Application page layout.
This should be doable with pure Visualforce (so technically there will be no Apex code ;))
Something as simple as
<apex:relatedList list="Contacts" subject="Application__c.Opportunity__r.AccountId" />
would be a good start (if you want your own layout and not a rel. list - you should be still able to pull it off with <apex:repeat> or <apex:pageBlockTable>.
There's one BUT here: it's not a field, just a display trick. Forget about using it in reports, mobile applications etc.
Another way - would it be acceptable to be 1 click away from these contacts? You could make a report "Account with Contacts", filter it by Id of one Account and later use "URL hacking" to change the filter depending on from which Application you'll click it. This link could be either a formula field or a real custom button/link. Technically - it's pure config, no apex & VF.
You can read more about URL hacking at Ray Dehler's excellent post and specifically about dynamic Reports here or here.

Cognos : Persisting Checkbox state across Multiple Pages

On the Cognos Report Results Page, we need to have a checkbox for each row.
The checkbox is designed using HTMLITEM tag.
However, the problem we face is that the state of the checkbox (checked or unchecked) is not persisted when we go to the next page/previous page.
I am very new to Cognos and I need to know if there is a way to do this.
I am fairly good at JAVAScripting and JSP, but since we only have access to HTML elements and not JSP Tags (Cognos uses CGI anyways), I cannot get the request object.
If there is some way to retrieve the request objects parameters of previous submit(previous page), that would help in solving the issue to a large extent, I feel.

There isn't really enough information on what your end goal is to be able to assist you with this properly. There are a few ways that spring to mind that would allow you to use JS on the report to remember previously checked items, but there may be a much better way to do this depending on your requirements.
Without having more details, the first thing that leaps to mind is simply having some JavaScript set and unset cookie values on check/uncheck on the checkbox.
Note, there could be a variety of other ways to work this, including upping the number of visible rows per page, etc...
You can create a dataitem in a query where you can determine whether your checkbox should be checked or not. In the design of your list on the report page you can render a HTMLItem within the list, and base the HTMLItem on a DataItem. Your HTML must than be something like
<input type="checkbox" value="""+ [DataItemValueToPass] + """ " + [DataItemCheckedOrNot] ></input>
