Do this inside the loop:

<div class="slider-wrapper theme-default">
    <div id="slider" class="nivoSlider"> 
    <?php
        $count = 1;
        $the_query = new WP_Query( array('post_type' => 'post', 'cat' => '10', 'posts_per_page' => '4'));
        while ( $the_query->have_posts() ) : $the_query->the_post();        
        $imageArray = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), 'noticia_destaque_image2' );
        $imageURL = $imageArray[0]; // here's the image url						
        ?>
        <a href="<?php the_permalink(); ?>"><img src="<?php echo $imageURL; ?>" alt="" title="#htmlcaption<?php echo $count; ?>" /></a>
        <div id="htmlcaption<?php echo $count; ?>" class="nivo-html-caption">
            <strong style="text-transform:uppercase; font-size:13px"><?php the_title(); ?></strong><br />
            <?php the_excerpt(); ?>
        </div>
        <?php $count++; ?>
    <?php endwhile; wp_reset_query(); ?> 
    </div>                   
</div>

But there’s still a little trick you got to do on jquery.nivo.slider.js. Just add the attribute ‘a’ to the children list (line 35):

change this: var kids = slider.children();

for this: var kids = slider.children(‘a’);

WP-caption

Lorem ipsum dolor isset

If you want to change the way wordpress set the width for the wp-caption div just go to wp-includes/media.php and change on this line:

return '<div ' . $id . 'class="wp-caption ' . $align . '" style="width: ' . (10 + (int) $width) . 'px">'

10 to whatever value you need.

Or maybe you want ot try this:

add_filter('shortcode_atts_caption', 'fixExtraCaptionPadding');
 
function fixExtraCaptionPadding($attrs)
{
    if (!empty($attrs['width'])) {
        $attrs['width'] -= 10;
    }
    return $attrs;
}

Create xml on admin logout

<?php
function geraxml() {
$name = "fulano";
//FILE
$file = "data.xml";
//OPEN FILE
$pointer = fopen($arquivo, "w");
//WRITE ON FILE
fwrite($pointer, "<data>");
fwrite($pointer, "<settings>");
fwrite($pointer, "<width>100%</width><height>100%</height>");
fwrite($pointer, "</settings>");
fwrite($pointer, "<item>");
fwrite($pointer, "<name>".$name."</name>");
fwrite($pointer, "</item>");
fwrite($pointer, "</data>");
//CLOSE FILE
fclose($pointer);
}
add_action("wp_logout", "geraxml");
?>

The file will be created in the root folder. Very useful if you need to create a xml file out of a nextgen gallery to be used by a flash gallery for instance.

<?php wpe_excerpt('wpe_excerptlength_size1', 'wpe_excerptmore'); ?>

Adding a Custom Meta Box

/* Use the admin_menu action to define the custom boxes */
add_action('admin_menu', 'nyc_boroughs_add_custom_box');
 
/* Adds a custom section to the "side" of the post edit screen */
function nyc_boroughs_add_custom_box() {
add_meta_box('nyc_boroughs', 'Applicable Borough', 'nyc_boroughs_custom_box', 'post', 'side', 'high');
}
 
/* prints the custom field in the new custom post section */
function nyc_boroughs_custom_box() {
//get post meta value
global $post;
$custom = get_post_meta($post->ID,'_nyc_borough',true);
 
// use nonce for verification
echo '<input type="hidden" name="nyc_boroughs_noncename" id="nyc_boroughs_noncename" value="'.wp_create_nonce('nyc-boroughs').'" />';
 
// The actual fields for data entry
echo '<label for="nyc_borough">Borough</label>';
echo '<select name="nyc_borough" id="nyc_borough" size="1">';
 
//lets create an array of boroughs to loop through
$boroughs = array('Manhattan','Brooklyn','Queens','The Bronx','Staten Island');
foreach ($boroughs as $borough) {
echo '<option value="'.$borough.'"';
if ($custom == $borough) echo ' selected="selected"';
echo '>'.$borough.'</option>';
}
 
echo "</select>";
}
 
/* use save_post action to handle data entered */
add_action('save_post', 'nyc_boroughs_save_postdata');
 
/* when the post is saved, save the custom data */
function nyc_boroughs_save_postdata($post_id) {
// verify this with nonce because save_post can be triggered at other times
if (!wp_verify_nonce($_POST['nyc_boroughs_noncename'], 'nyc-boroughs')) return $post_id;
 
// do not save if this is an auto save routine
if (defined('DOING_AUTOSAVE') && DOING_AUTOSAVE) return $post_id;
 
$nyc_borough = $_POST['nyc_borough'];
update_post_meta($post_id, '_nyc_borough', $nyc_borough);
}

We can use this field value in our template just as we would embed generic custom fields.

echo get_post_meta($post->ID, '_nyc_borough', true);
