Question

Ok so I have value being returned from a database in an ARRAY Some pages have 3 values, and some pages have 10, and other have 0.

If a page returns a value I want the label to appear ONCE, hence not in the loop.
label -> $key_label = '<span class="hl_reference"><u>key references:</u></span>';

If the page doesn’t have any $reference_keys I don’t want the label to appear, hence $key_label = false;

So I want to check the ARRAY for a value and if >= 1: the label will also appear.

My code doesn’t seem to be validating if(array($value => 1) && !$key_label) I guess my syntax is wrong or maybe I should be using a different function?

Thanks for help!

$key_label = false;
$key_label = '<span class="hl_reference"><u>key references:</u></span>';

foreach($reference_keys as $value)
{
    echo $value .'&nbsp;';
}

if(array($value => 1) && !$key_label) 
{
    $key_label = true; 
    echo $key_label;
};

——————————-UPDATE—————————–

This code appears to only work on pages with only 1 reference_key… Strange as count is set to >= 1

$key_label = '<span class="hl_reference"><u>key references:</u></span>';

foreach($reference_keys as $value)
{
   echo $value .'&nbsp;';
}
$result = count($value);
if ($result > 1)
{
  echo $key_label;
}

Most recent code by John C appears to work but it displays a “1” immediately before the 2nd $reference_key on each page. But it does only display on pages with $reference_key

$key_flag = false;
$key_label = '<span class="hl_reference"><u>key references:</u></span>';

foreach($reference_keys as $value)
{
if (!empty($value)) {
    if (!$key_flag) {
        echo $key_label;
        $key_label = true;
    }
    echo $value .'&nbsp;';
}
};

John C solved this one.. Working code below! Thank you everyone! ->

$key_flag = false;
$key_label = '<span class="hl_reference"><u>key references:</u></span>';

foreach($reference_keys as $value)
{
if (!empty($value)) {
    if (!$key_flag) {
        echo $key_label;
        **$key_flag = true;**
    }
    echo $value .'&nbsp;';
}
};

If I read this right, you would like to display the span if there are values in your $reference_keys array, then loop through and show the values in the array.

To do this, you could do something like:

if (!empty($reference_keys) && count($reference_keys) > 0) {
    echo '<span class="hl_reference"><u>key references:</u></span>';
    foreach($reference_keys as $value)
    {
       echo $value .'&nbsp;';
    }
}

EDIT If there are empty values in the $reference_keys array, then the count will come back greater than 0 but no keys will show. If this is the case this code will work around:

$key_flag = false;
$key_label = '<span class="hl_reference"><u>key references:</u></span>';

foreach($reference_keys as $value)
{
    if (!empty($value)) {
        if (!$key_flag) {
            echo $key_label;
            $key_flag = true;
        }
        echo $value .'&nbsp;';
    }
}
