<?php

/* Functions for processing custom fields */

function get_custom_field($field, $format = '', $date_format = 'F j, Y')

{

$fetch = $field;

$fetch = get_post_custom_values($field);

$fetch = $fetch[0];

// Date

if ($format == 'date' & $fetch !='') $fetch = format_date($fetch, $date_format);

// Text Block

elseif ($format == 'text_block') $fetch = wpautop($fetch);

// HTML

elseif ($format == 'html') $fetch = html_entity_decode($fetch);

// Google Map

elseif ($format == 'google_map') $fetch = display_google_map($fetch);

return $fetch;

}

function custom_field($field, $format = '', $date_format = 'F j, Y')

{

echo get_custom_field($field, $format, $date_format);

}

function format_date($date, $date_format)

{

$date = date($date_format, $date);

return $date;

}

function display_google_map($code)

{

$code = html_entity_decode($code);

// Remove the info bubble. Usually desirable, but use the html format if unwanted.

$code = str_replace("output=embed", "output=embed&iwloc=near", $code);

return $code;

}

?>

<?php

/* Functions for processing custom fields */

function get_custom_field($field, $format = '', $date_format = 'F j, Y')

{

$fetch = $field;

$fetch = get_post_custom_values($field);

$fetch = $fetch[0];

// Date

if ($format == 'date' & $fetch !='') $fetch = format_date($fetch, $date_format);

// Text Block

elseif ($format == 'text_block') $fetch = wpautop($fetch);

// HTML

elseif ($format == 'html') $fetch = html_entity_decode($fetch);

// Google Map

elseif ($format == 'google_map') $fetch = display_google_map($fetch);

return $fetch;

}

function custom_field($field, $format = '', $date_format = 'F j, Y')

{

echo get_custom_field($field, $format, $date_format);

}

function format_date($date, $date_format)

{

$date = date($date_format, $date);

return $date;

}

function display_google_map($code)

{

$code = html_entity_decode($code);

Limit Search Results to Specific Post Types

On placing the following shortcode in your functions.php file, it lets you exclude your custom post types from search results.

<?php

function SearchFilter($query) {

if ($query->is_search) {

$query->set('post_type',array('post','page'));

}

return $query;

}

add_filter('pre_get_posts','SearchFilter');

?>

<?php

function SearchFilter($query) {

if ($query->is_search) {

$query->set('post_type',array('post','page'));

}

return $query;

}

add_filter('pre_get_posts','SearchFilter');

Different admin and theme languages

The shortcode will define one language for admin and the other for theme.

<?php

// setup one language for admin and the other for theme

// must be called before load_theme_textdomain()

function set_my_locale($locale) {

$locale = ( is_admin() ) ? "en_US" : "it_IT";

setlocale(LC_ALL, $local );

return $locale;

}

add_filter( 'locale', 'set_my_locale' );

?>

<?php

// setup one language for admin and the other for theme

// must be called before load_theme_textdomain()

function set_my_locale($locale) {

$locale = ( is_admin() ) ? "en_US" : "it_IT";

setlocale(LC_ALL, $local );

return $locale;

}

add_filter( 'locale', 'set_my_locale' );
