How to hide a block if the src field is empty?-CodePudding

Using PHP, I display a link to a picture in src, but this picture is not always there and it turns out that a block with a picture remains empty and takes up space. How can I hide a block with an empty src?

I will answer as I Understand the question,

I will assume you have a variable with the picture URL, and that data is send through POST method

<?php

$picURL = $_POST['picURL'];

if(!isset($picURL)){
    echo "<img src=${picURL}>";
}
?>

here what I am doing is checking whether the variable is set or not if the $picURL variable is set I assume there is a URL and render the image.

You can do it using PHP.

<?php if(!empty($img_url)){ ?>
<img src ="<?php echo $img_url; ?>" alt ="Image name" />
<?php } ?>

It will only display the image in which src is not empty.
