Easy snippet, but it's got me stumped...

...displays an image if there’s a url spec’d in the TV, however, when there’s no TV value the code’s still displaying (missing image icon) on the page. For Evo.

<?php
// Checks for image url in TV and displays if present

$document_tvs = $modx->getTemplateVarOutput(true, $id);
$image = $document_tvs['titleImage'];

$output='';
if (isset($image)) {
     $output = '<div class="title-img" ><img src="[*titleImage*]" /></div>';
}
     return $output;
?>

Called in the template as [[displayImage]].

(I know I can use phx but it’s out of action at the moment - thanks)

Mostly harmless.

Hi hotdiggity.

$id is not set

$id = $modx->documentIdentifier;

Give this a try and see if it helps:

<?php
// Checks for image url in TV and displays if present

$image =$modx->documentObject['titleImage'][1];

$output='';
if (isset($image)) {
     $output .= '<div class="title-img" ><img src="'.$image.'" /></div>';
}
     return $output;
?>

No difference. No problem with image displaying when URL is spec’d in TV.

Below is the old snippet works but its not the most elegant solution (despite only a few lines diff). Just been trying to write leaner code but maybe this is a case of "if it ain’t broke, don’t fix it"?!

<?php
$document_tvs=$modx->getTemplateVarOutput(true, $id);
$image=$document_tvs['titleImage'];

if ( $image == '' ) {
     return;
} else {
     echo '<p><img src="[*titleImage*]" alt="[*longtitle*]"></p>';
     return;
}
?>

Mostly harmless.
