Lightbox with SQL [duplicate]

This question already has answers here:
How do I iterate over the results in a MySQLi result set?
(2 answers)
Closed last year.
i'm trying to create a Lightbox Image Gallery using a SQL Database.
I'm storing the images as Image Hoster links in my database.
It is only showing one image using my code. Is it possible to show all?
$res = "SELECT * FROM user";
$result = $conn->query($res);
while($myRow = $result->fetch_array())
{
$Foto = $myRow["Foto"];
}
?>
<img id="myImg" src="<?php echo $Foto; ?>">
<div id="myModal" class="modal">
<span class="close">×</span>
<img class="modal-content" id="img01">
<div id="caption"></div>
</div>
<script>
var modal = document.getElementById("myModal");
var img = document.getElementById("myImg");
var modalImg = document.getElementById("img01");
var captionText = document.getElementById("caption");
img.onclick = function(){
modal.style.display = "block";
modalImg.src = this.src;
captionText.innerHTML = this.alt;
}
var span = document.getElementsByClassName("close")[0];
span.onclick = function() {
modal.style.display = "none";
}
</script>

I managend to load all Images and i can open the first image onclick. How can i open all images onclick?
<?php
$res = "SELECT * FROM user";
$result = $conn->query($res);
while($myRow = $result->fetch_array())
{
echo "<tr>";
echo "<span class='Gallerie'>" . $myRow['Foto'] . "</span>";
echo "</tr>";
}
?>
<div id="myModal" class="modal">
<span class="close">×</span>
<img class="modal-content" id="img01">
<div id="caption"></div>
</div>
<script>
var modal = document.getElementById("myModal");
var img = document.getElementById("image");
var modalImg = document.getElementById("img01");
var captionText = document.getElementById("caption");
img.onclick = function(){
modal.style.display = "block";
modalImg.src = this.src;
captionText.innerHTML = this.alt;
}
var span = document.getElementsByClassName("close")[0];

Modal Image Issue in JavaScript

I'm trying to include an image modal into my photo gallery. I've been trying to work with a version of this example:
http://www-db.deis.unibo.it/courses/TW/DOCS/w3schools/howto/howto_css_modal_images.asp.html
The example only works with one image since it accesses the image through its ID. I've tried to modify it and just have it access the image through its class. But that doesn't work. How would I have to modify the JS code to make it work with any image in a gallery?
Thank you!!!
Modified code:
HTML:
<img class="galleryPic" src="assets/images/test images/globes.jpg" alt="Old globes" width="300" height="200">
<img class="galleryPic" src="assets/images/test images/palmtrees.jpg" alt="Palmtrees in front of the evening sky" width="300" height="200">
<!-- The Modal -->
<div id="myModal" class="modal">
<!-- The Close Button -->
<span class="close" onclick="document.getElementById('myModal').style.display='none'">×</span>
<!-- Modal Content (The Image) -->
<img class="modal-content" id="img01">
<!-- Modal Caption (Image Text) -->
<div id="caption"></div>
</div>
JS:
// Get the modal
var modal = document.getElementById('myModal');
// Get the image and insert it inside the modal - use its "alt" text as a caption
var img = document.getElementsByClass('galleryPic');
var modalImg = document.getElementById("img01");
var captionText = document.getElementById("caption");
img.onclick = function(){
modal.style.display = "block";
modalImg.src = this.src;
modalImg.alt = this.alt;
captionText.innerHTML = this.alt;
}
// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];
// When the user clicks on <span> (x), close the modal
span.onclick = function() {
modal.style.display = "none";
}

There is not such thing as document.getElementsByClass(), there is document.getElementsByClassName() which returns a list of elements if found.
So you'll need "loop" through the list:
// Get the modal
var modal = document.getElementById('myModal');
// Get the image and insert it inside the modal - use its "alt" text as a caption
var imgs = document.getElementsByClassName('galleryPic');
var modalImg = document.getElementById("img01");
var captionText = document.getElementById("caption");
for (let i = 0; i < imgs.length; i++) {
imgs[i].onclick = function() {
modal.style.display = "block";
modalImg.src = this.src;
modalImg.alt = this.alt;
captionText.innerHTML = this.alt;
}
}
// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];
// When the user clicks on <span> (x), close the modal
span.onclick = function() {
modal.style.display = "none";
}

Modal images have troubles with classes

I got this modal script to display bigger images on my site. It worked well, but only with 1 image. When i tried to add more images - script didn't worked, and nothing was happening. Can someone tell me what am I doing wrong?
Here's some code:
var modal = document.getElementById("myModal");
// Get the image and insert it inside the modal - use its "alt" text as a caption
var img = document.getElementsByClassName("zdjecie");
var modalImg = document.getElementById("img01");
var captionText = document.getElementById("caption");
img.onclick = function() {
modal.style.display = "block";
modalImg.src = this.src;
captionText.innerHTML = this.alt;
}
// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];
// When the user clicks on <span> (x), close the modal
span.onclick = function() {
modal.style.display = "none";
}
<img class="zdjecie" style="max-height: 16rem;max-width: 16rem;" src="example.jpg">
When I was using ID's instead of classes it worked well - but i couldn't add more images - that's why i need to use classes. Someone has any ideas? I'd be greatful

The document.getElementsByClassName returns an array, which contains all the dom has the zdjecie class.
So you have to loop through this array to add the event, or put these images inside a container and use event-delegation, which is a more efficient way. Because it just bind event once. More about event-delegation: https://javascript.info/event-delegation`
Here is the code using event-delegation.
var handleImageClick = function(evt){
if(evt.target.className.indexOf('zdjecie') === -1) return;
modal.style.display = "block";
modalImg.src = evt.target.src;
captionText.innerHTML = evt.target.alt;
}
// Get the image and insert it inside the modal - use its "alt" text as a caption
var modal = document.getElementById("myModal");
var imageContainer = document.getElementById("imageContainer");
var modalImg = document.getElementById("img01");
var captionText = document.getElementById("caption");
imageContainer.addEventListener('click', handleImageClick)
// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];
// When the user clicks on <span> (x), close the modal
span.onclick = function() {
modal.style.display = "none";
}
.zdjecie{
background-color: yellow;
width: 100px;
height: 100px;
display: inline-block;
}
<div id="imageContainer">
<img class="zdjecie" alt="1" style="max-height: 16rem;max-width: 16rem;" src="example1.jpg" />
<img class="zdjecie" alt="2" style="max-height: 16rem;max-width: 16rem;" src="example2.jpg" />
<img class="zdjecie" alt="3" style="max-height: 16rem;max-width: 16rem;" src="example3.jpg" />
<img class="zdjecie" alt="4" style="max-height: 16rem;max-width: 16rem;" src="example4.jpg" />
</div>
<div id="myModal">
<span class="close">x</span>
<img id="img01" style="max-height: 16rem;max-width: 16rem;" />
<p id="caption"></p>
</div>

Dynamic image in modal view with javascript in Laravel 5.2

I need a little advice to display images dynamically.
I am currently using this script from an example of W3Schools:
http://www.w3schools.com/howto/howto_css_modal_images.asp
Here is the script:
<script>
// Get the modal
var modal = document.getElementById('myModal');
// Get the image and insert it inside the modal - use its "alt" text as a caption
var img = document.getElementById('myImg');
var modalImg = document.getElementById("img");
var captionText = document.getElementById("caption");
img.onclick = function(){
modal.style.display = "block";
modalImg.src = this.src;
captionText.innerHTML = this.alt;
}
// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];
// When the user clicks on <span> (x), close the modal
span.onclick = function() {
modal.style.display = "none";
}
</script>
#foreach($properties->files as $file)
<div class="col-md-6 thumb">
<a class="thumbnail">
<img id="myImg" src="{{ URL::asset('uploads/products/' . $file->name) }}" alt="{{ $file->name }}" width="300" height="200">
</a>
</div>
<div id="myModal" class="modal">
<span class="close" onclick="document.getElementById('myModal').style.display='none'">×</span>
<img class="modal-content" id="img">
<div id="caption"></div>
</div>
#endforeach
I need to display the images that are displayed dynamically in the thumbnail, because only the first image in the list is showing.
In the view the images are shown like this:
The first image is displayed in a modal view, but the second does not:
This is my show method in Propertycontroller:
Public function show ($ id)
     {
         $ Properties = Property :: find ($ id);
        
         $ Files = File :: where ('property_id', $ properties-> id) -> get ();
        
         Return view ('properties.show', compact ('properties', 'files'));
     }
This requirement is related to:
Show image file by id in Laravel 5.2
How can I display the images in the modal view when clicking them?

It's showing only first image because your id will be same for all images. Use for loop index to give unique id to img tag like below :
#foreach($properties->files as $index=>$file)
<div class="col-md-6 thumb">
<a class="thumbnail">
<img id="myImg<?php echo $index ?>" src="{{ URL::asset('uploads/products/' . $file->name) }}" alt="{{ $file->name }}" width="300" height="200" onclick="showImage(this,<?php echo $index ?>)">
</a>
</div>
#endforeach
showImage() function will pass the unique $index to your script and do the thing.
<script>
function showImage(element,i){
// Get the modal
var modal = document.getElementById('myModal');
// Get the image and insert it inside the modal - use its "alt" text as a caption
var img = document.getElementById('myImg'+i);
var modalImg = document.getElementById("img");
var captionText = document.getElementById("caption");
modal.style.display = "block";
modalImg.src = element.src;
captionText.innerHTML = element.alt;
}
</script>
similarly you can set closing the modal logic. I hope this help you.
