Only display when there is something there!

HELP,

I had some custom code written by a developer who is now unreachable. Part of the code creates a link to a document:

 

foreach ($prop->epcs as $epc){

$html = $html . sprintf('<p><a href="%s">View EPC</a></p>',(string)$epc->epc);

}

 

The code is using an XML feed to poluate a property database. The issue I have is that this piece of code is generating a link even if there is no document present. I need it to only display the link if there is a value in the $epcs / $epc variable.

 

Can anyone provide a piece of updated code that will only output the link if there is a value?

 

Hope that makes sense!

 

Thanks

This should work for you (untested) Or something similar would.

foreach ($prop->epcs as $epc){

if(empty($epc)){

echo "";

} else {

$html = $html . sprintf('<p><a href="%s">View EPC</a></p>',(string)$epc->epc);

}

forgot to close the loop!

 

}

For what it's worth, the first part of the if isn't necessary.

 

<?php
foreach($prop->epcs as $epc) {
    if(!empty($epc->epc)) {
         $html = $html . sprintf('<p><a href="%s">View EPC</a></p>',(string)$epc->epc);
    }
}
?>
