query_posts where custom field is true

meta_key is deprecated as of Version 3.1 in favor of ‘meta_query’.
try it with this:

<?php
$args = array(
'orderby' => 'title',
'order' => 'ASC',
'meta_query' => array('key' => 'featured')
);
?>
<?php query_posts( $args ); ?>

Thanks for this. How would I go about only showing posts where the value of that custom field was “true”? I’ve tried the following:

<?php
$args = array(
'orderby' => 'title',
'order' => 'ASC',
'meta_query' => array('key' => 'featured', 'value'=>'true')
);
?>
<?php query_posts( '$args' ); ?>

But that doesn’t show anything.

I’ve a feeling that you need to do it like this –

<?php
$args = array(
    'orderby' => 'title',
    'order' => 'ASC',
    'meta_query' => array(
        array = (
            'key' => 'featured',
            'value'=>'true'
        )
    )
);
query_posts( '$args' );
?>

This allows you to query multiple meta values with only one query.

Umm, I got an error: Parse error: syntax error, unexpected ‘=’, expecting ‘)’

Figured out where the error was:

<?php
$args = array(
    'orderby' => 'title',
    'order' => 'ASC',
    'meta_query' => array(
        array  (
            'key' => 'featured',
            'value'=>'true'
        )
    )
);
query_posts( '$args' );
?>

But that just seems to be bringing in any post where the “featured” custom field has content. Whereas I would like it where only posts with the text value of “true” are added.

I’ve used this code and it seems to be working okay but you say that meta_key is depreciated:

<?php query_posts( 'orderby=title&order=ASC&meta_key=featured&meta_value=true' ); ?>

This then only shows posts where the custom field of “featured” has the content “true” entered in the field.

I would be grateful for any suggestions though.

Yes, apologies, I added an extra ‘=’ by mistake. I’ve also just spotted quotes that should not be there for query_posts.

Try this, as the code above (once corrected) should have worked as the default for ‘compare’ is LIKE, but you never know…

<?php
$args = array(
    'orderby' => 'title',
    'order' => 'ASC',
    'meta_query' => array(
        array(
            'key' => 'featured',
            'value' => 'true'
            'compare' => 'LIKE'
        )
    )
);
query_posts($args);
?>

Spot on. Thanks so much for all of your help – really appreciated. There was just a missing comma after ‘true’ but all’s working well now.

You are welcome, glad I could be of help.
