Well, I found some help on the codex, and tried this:

<pre>
$meeting_city = $Record->pod_helper(‘filter_helper’, $Record->get_field(‘city’));
</pre>

But when I echo the the variable, nothing gets as an output. But with the same helper, when the code was first on the POD template (e.g. {@city, filter_helper} ) , it did work.

This is my filter_helper:

<pre>
<?php
$pick_array = $this->get_field($name);
$tmp = explode(‘?’, $_SERVER['REQUEST_URI']);
$link = $tmp[0];
parse_str($_SERVER['QUERY_STRING'], $tmp_query);

if (is_array($pick_array) && 0 < count($pick_array)) {
$output = "";
$sep = "";
foreach ($pick_array as $val) {
$output .= $sep;
$tmp_query[$name] = $val['id'];
$output .= "<a href=’" .$link ."?" . http_build_query($tmp_query) . "’>";
$output .= $val['name'] . "</a>";
$sep = ", ";
}
echo $output . "";
}
?>
</pre>
Should I change something in the helper as well?

@maor – I know it’s poorly documented, but pod_helper() accepts 3 parameters:

1st: Helper Name
2nd: Value to pass into helper
3rd: Column name

Notice how in your helper, you’re trying to use get_field($name). Since the name parameter isn’t getting passed in, nothing is getting found from get_field().

Try this instead:

<pre>$meeting_city = $Record->pod_helper(‘filter_helper’, $Record->get_field(‘city’), ‘city’);</pre>

Hi,

I had a POD template that showed the columns using a display helper, something like this:

<pre>
{@city, filter_helper}
</pre>

This helper is used to show the column’s value (since it’s a PICK array) and have it clickable to be filtered.

Now, I want to move the POD template, to be directly inside my WordPress page template. I use the code, something like:

<pre>
while ($Record->fetchRecord()) {
$meeting_city = $Record->get_field(‘city’, filter_helper);
echo ‘<div class="cell alignright">’ . $meeting_city . ‘</div>’;
some more fields here…etc…
} // end while
</pre>

That brings me an error, and doesn’t recognize the helper as an helper, but as an orderby field.
More than that, if I put just –
<pre>
$meeting_city = $Record->get_field(‘city’);
</pre>
It echoes an "Array" as a result.

So, how do I use my display helper when my code is directly on the WP page template, and not on a POD template?

Thanks

@logikal16 – Many thanks, it works great now!

Just for curiosity, if I understood the logics here, the value is passed from the column name that is already mentioned in the get_field(), so why does the pod_helper() must get both the value and the column name, rather than have the value pass its column name to the helper as well?
