shorturl | Generic implementation for interacting with various URL

I am attempting to create dynamic links to work as part of a referral system for my app. I believe I am successfully creating the links, however whenever I click on one from my notes app while running my app (which I am told should just open the app) I am directed to a Safari page then the App Store. This leads me to beleive the dynamic like for whatever reason isn't being handled at all by my app.

I am using a custom domain URI prefix, specifically https://mywebsite.com/invite and here is the complete code for creating my dynamic link

I'm building a URL Shortener, and I've decided to recyle the short ID's if possible to save space in my database. How can i check if 2 URL's lead to the same path?

For example, let's say a user generates a short URL for https://google.com/.

My app generates the following short id: jkU3

So if this user visits https://tiny.url/jkU3 my express server will redirect the visitor to https://google.com/.

This works like a charm, but know let's imagine another person visits https://tiny.url/ and generates a short URL for https://google.com. And another one comes and generates a short URL for https://www.google.com/, and another one comes and generates one for https://www.google.com. You get the point..

So far my app would have wasted 4 short ID's.

How can i prevent this from happening? Is there a regex for this?

This is the current code I have for generating short URL's:

I'm trying to get the value returned from an API query, but in all the ways I've done it, it either returns Undefined or [object Promise]. I've tried several solutions and I still haven't got something that works. Below is the last code I made to see if it worked but again without success.

so i building a url shortner which takes the url from python and generates a QR code in along with the shortUrl, i am using jinja2template for the UI, as i am very new to JavaScript the below code is mostly copied from Youtube and Internet.

This is the class which will show the converted shortUrl and will have a copy link button next o it

So, let's say I put "h" in a post form and I have 5 things in my data base:

1st Entry - Name: Hello

2nd Entry - Name: Height

3rd, 4th, 5th entries do not have a word that has "h" in them

How would I make it return all of the ones that include the string provided (like Hello and Height)

Here is my current setup:

I make a remake of an extension so I stuck in the last work that I must to do. I created a twig for admin which displays a list that take data from a table in the database. In each row of the list I created a button that I want to fix specific cell of the table. So each line has its own id.

See the image from page list:

I made the controller file but I stuck in model file that must do the rest work.

In the following code I have to change something so that by pressing the repair button it reads the specific id.

edited, i cut it short.

code variable is assigned

firstly i need to trigger a php script with get request, output shouldn't be saved "https://flower.nyaizhel.ml/fun/carbon/?code=" + code

then, when the request above completed, send get request to "https://flower.nyaizhel.ml/fun/carbon/shorturl.php?short&code=" + code and save the response to a variable,

for https://flower.nyaizhel.ml/fun/carbon/shorturl.php?short&code=ii it should be 6, see the url

i tried fetch, no result

I found the time to experiment with an extension for the opencart and I'm stuck.

I have in model php file the following lines

I have a problem that a z-index property is not applying. Is there a concrete dependency to other properties?

It looks right now like that, the Avada Theme sticky header is above everything:

The z-index of the header menu is "only" 10011:

Even if I set a style on ".fdm-ordering-sidescreen" with z-index to 200000, it is not above the menu. WHY is that? Shouldn't it become on top?
