My WP_Query didn't work after upgrading to WordPress 3.2

Question

I created a custom loop using WP_Query for my featured content slider.

<?php
$slider_query = new WP_Query();
$slider_query->query("posts_per_page=5&tag=".(get_option('cgr_slider_tag'))" ");?>
<?php while ($slider_query->have_posts()) : $slider_query->the_post(); ?>

    <article class="slide-item ">

     ....

It works fine in previous 3.1.4 , but after upgraded to 3.2 that code is just didn't work. No error found in WP_Debug mode, and Then i try to directly assign the tag name without using the get_option :

<?php
$slider_query = new WP_Query();
$slider_query->query("posts_per_page=5&tag=tag1");?>
<?php while ($slider_query->have_posts()) : $slider_query->the_post(); ?>

 <article class="slide-item ">


  ....

it works, so i assume the problem is the get_option thing. I've checked the database and other part of the theme that also using get_option and found no problem.

I start thinking that the problem is I didn't code the get_option part correctly, i'm php noob so maybe it's about encapsed string or others.

Any help will be appreciated.

Answer 1

this line:

$slider_query->query("posts_per_page=5&tag=".(get_option('cgr_slider_tag'))" ");

should be:

$slider_query->query("posts_per_page=5&tag=".(get_option('cgr_slider_tag')));
