Dear All

I know how to check if a TV is empty of not

[[*image-1:ifnotempty=`not empty`]]

My problem, I have serveral TV and if all of them are empty, I do not want to display a div

[[*image-1:ifnotempty=`<div>Hello</div>`]]
[[*image-2:ifnotempty=`<div>Hello</div>`]]
[[*image-3:ifnotempty=`<div>Hello</div>`]]
[[*image-4:ifnotempty=`<div>Hello</div>`]]
[[*image-5:ifnotempty=`<div>Hello</div>`]]
[[*image-6:ifnotempty=`<div>Hello</div>`]]

I do not know how to modify the above code to display only

<div>Hello</div>

if at least on of the TV is not empty.

I need to have something like this

if (*image-1:ifnotempty OR *image-2:ifnotempty OR *image-2:ifnotempty ...){
   then display : <div>Hello</div>
}

Do see?
Thank

sounds like a MIGX-TV could be the better solution to add as many images as you like to your resources.

Sounds like a good use case for a snippet with your custom logic

I'm not positive what you're trying to do, but this might be it. It will depend on how the TVs are set up. You'll only need one tag.

[[!ShowImages]]

<?php
/* ShowImages snippet */
$output = '';

$tvs = array(
    'image-1',
    'image-2',
    /* etc. */
);

foreach ($tvs as $tv) {
   $image = $modx->resource->getTVValue($tv);

   if (! empty($image)) {
      $output .= "\n" . '<div>' . $image . '</div>';
   }
}

return $output;
