Hi guys, 

how can I do with php to show the div containing the image (if the image exists)?
Thanks for your help.

How to tell if a page has images present

It is a good idea to check if an image(s) field has something in it before attempting to output it. When set to contain multiple images, you can tell if a page contains one or more images by using the count() function:

if(count($page->images)) {
  // the page has one or more images
}   

When set to contain a max of one (1) image, then you can just check if your image field has a value:

if($page->image) {
  // an image is present
}

Thank You for your response. 

In my case I need to write this, because I am in the post archive:

if ($ story-> imagefieldname) {
...
}

But it does not work as it should because it recalls an image in other posts ...

Sorry, I don't understand what you mean by 'post archive'.

The if condition you write, only work if the imagefieldname field is configured to contain a max of one (1) image. It is the case ?

It is right (sorry I come from WP). But in my case I have a page with a list of articles and the image field is also called in the article that has no image.

I think I am missing something, because to achieve what you asked, you have to write :

[...]

foreach($stories as $story) {
    if(count($page->imagefieldname)) { // images exist, we show the div
	echo "<div>...</div>";
    }
    
    [...]
}

[...]

Thanks so much! Now it works perfectly. Can I offer you a coffee? ☕

To be exact, I did this: 

if(count($story->imagefieldname)) {
	...
}

Thank you again!
