only show list if present, simple logic

eviljoker7075

Hello people. I am trying to use an IF statement to display a list of data only if it has been entered by a user. If it is not present then nothing is displayed.

However the only thing I can achive is the list, but each item has the section heading "for fans of:" in front of it. I would like to have the section heading, with a list displayed underneath it (he heading also only being displayed when values are present.

The code I am using is:

 <?php
foreach ((array)$field_for_fans_of as $item) {
if($item['view']){
?>
      <div class="field-item"><b>For fans of:</b> <?php print $item['view'] ?></div><br>
    <?php }}?>

The effect I want to create is as follows:
For fans of:
item #1
item #2
item #3

The effect I want am getting is as follows:
For fans of: item #1
For fans of: item #2
For fans of: item #3

Try:

if (!empty($field_for_fans_of))

then

echo "for fans:";

and the go with the foreach

If I understand your logic correctly:

<?php

if (!empty($field_for_fans_of)) {
$msg = '<div class="field-item"><b>For fans of:</b>';

foreach ((array)$field_for_fans_of as $item)
    $msg .='<BR>'.$item['view'];

$msg .='</div><br>';}

That looks right, but when I add it to my page all content is lost and nothing shows up...

Are you printing the $msg at the end?

Add this if you haven't:

echo $msg;

Where is the "view" coming from? Is it a multi-dimensional array that you're using?

If it is a single-dimension use:

<?php

$field_for_fans_of = array("item1","item2","item3");

if (!empty($field_for_fans_of)) {
$msg = '<div class="field-item"><b>For fans of:</b>';

foreach($field_for_fans_of as $item)
$msg .='<BR>'.$item;

$msg .='</div><br>';}

<?php echo $msg;?>
