I am trying to render a HTML grid layout in a php file called gardenshop.php. Within the grid container should be grid items in the form of Bootstrap 5 cards that are created dynamically. The grid container (a ) has a class of .items-wrapper. Each card should consist of the following:
a)A container which is a of class of container mt-3 slides-container (if the card has more than one image) or container mt-3 (if the card has only one image).
c)Nested within b) are the image or images. I have a database of treeseeds and some entries have only one image treeImage1 while other treeseed types have jave more than one images with treeImage2 and treeImage3 not being NULL.
d)Below the images and also nested within b) is a another div for the cardBody with a class of “.card-body”
e)Nested within d) should be a element with a class of “.card-title” that will have the commonName of the treeseed.
element with text saying “Information:” and has a class of “.info-text”.
Now referring back to g) the data for these columns for each treeseed will be listed a
list items that I was speaking about for g), except for ID as the viewer of the gardenshop.php website does not need to see the record id.
I am using PDO (PHP Data Object) logic within a file called shopconnect.php to make a connection to my database and request the data back with MySQL select queries as usual.

So from the code above I am am getting the data back from database but like I said earlier I want the information presented in a html grid layout with bootstrap cards. The problems occur in the last part of the code with the nested foreach loop (see asterisks in code) and when I start used DOM elements. Essentially, I want to check on each iteration whether treeseed record has only one image or more. If a treeseed has more than one image then I want to render a bootstrap 5 card that has a slideshow where they user can click the dots/circles of navigation arrowheads to see the separate images. //***TEST is just a echo statement to test if I am getting any data back.
plusSlides() and currentSlide() are javascript functions in slidelogic.js and the classes “mySlides fade” are classes that are used in slidelogic.js. See the JavaScript file below.
//slidelogic.js
let slideIndex = 1;
showSlides(slideIndex);
//Next/previous controls
function plusSlides(slideNum){
showSlides(slideIndex += slideNum);
}
// Thumbnail image controls
function currentSlide(n) {
showSlides(slideIndex = n);
}
function showSlides(number){
let i;
let slides = document.getElementsByClassName("mySlides");
let dots = document.getElementsByClassName("dot");
if(number > slides.length){
slideIndex = 1;
}
if(number < 1){
slideIndex = slides.length;
}
for (i = 0; i < slides.length; i++) {
slides[i].style.display = "none";
}
for (i = 0; i < dots.length; i++) {
dots[i].className = dots[i].className.replace(" active", "");
}
slides[slideIndex-1].style.display = "block";
dots[slideIndex-1].className += " active";
}
function currentSlide(number){
displaySlides(slideIndex = number)
}
Then I import the JavaScript file above (slidelogic.js) and shopconnect.php into gardenshop.php

}
I tried my code out above via XAMMP (render the php file gardenshop.php using the Apache on it)
I get the following output in the image below. I would like to know how to get the bootstrap 5 cards to render in a grid dynamically. Dynamically in the sense I don’t need to hard code the grid items; if I want to add more treeseed data to my database I can do that and then when the gardenshop.php webpage is loaded (going via localhost in my browser) it will render the correct number of grid items (cards) automatically.
