Display link when file exists

Hello!

I'm using the following code to display a link only when the file exists:

<?php
if ($form->data["Banner2"]["documento_banner"] !== ' ') {
  echo "<a href='*my path*/com_chronoforms5/chronoforms/uploads/banner2/{Banner2.documento_banner}'>Descargar archivo</a><br>";
} else {
  echo "No file";
}
?>

The problem is it still displays the line "Descargar archivo" even when the file doesn't exist instead of displaying "No file", it's like the "else" wasn't there.

Can you help me please?

Hi nams09,

You are checking !== ' ' - and there is a space between the ' '. It should be '' with no space, or perhaps better:

<?php
$message = 'No file';
if ( !empty($form->data['Banner2']['documento_banner']) ) {
  $image_uri = JURI::root().'/com_chronoforms5/chronoforms/uploads/banner2/'.$form->data['Banner2']['documento_banner'];
  $message = "<a href='{$image_uri }'</a><br>";
} 
echo $message;
?>

Hi Greyhead!

Thanks for your reply. Unfortunately this didn't work, looks like it's not recognizing the !empty command, which is why I used !== ' ' instead. Any idea of what could be the problem?

Could it be an issue if I'm using this code in the View Action?

It's actually Chronoconnectivity, I used $row and it works now, thanks! 😀
