Bir müşteri için yapmış olduğum galeri eklentisini paylaşıyorum, belki ihtiyaç duyan vardır böyle bir şeye..
Wordpress yazı ekleme sayfasında yeni bir alan oluşturarak burada postunuza resimler yüklemenizi sağlar.
* Limitsiz resim ekleyebilirsiniz
* Sürükleyip bırakarak sıralamayı değiştirebilirsiniz
* Tek seferde birden çok resim seçebilir/yükleyebilirsiniz
https://github.com/demirdoven/image-...t-in-wordpress
(Burada nasıl kullanılacağını anlattım fakat Türkçe olarak aşağıda da anlatıyorum..)
Kurulum
Önce resim yükleme alanını oluşturalım (meta box)
* Ben "house" adlı custom post type için oluşturdum, siz normal yazılar için yapacaksanız kodlardaki "house" yazan yerleri "post" olarak değiştirin.
function add_gallery_mb(){
add_meta_box(
'post_gallery',
'Gallery',
'gallery_img_func_callback',
'house',
'normal',
'core'
);
}
add_action( 'admin_init', 'add_gallery_mb' );Resim yükleme alanının ne yapacağını yazalım..
function gallery_img_func_callback(){
wp_nonce_field( basename(__FILE__), 'sample_nonce' );
global $post;
$gallery_data = get_post_meta( $post->ID, 'gallery_data', true );
?>
<div id="dynamic_cont">
<div id="img_box_container">
<?php
if ( isset( $gallery_data['image_url'] ) )
{
for( $i = 0; $i < count( $gallery_data['image_url'] ); $i++ )
{
?>

Gelelim resimleri nasıl kullanacağımıza...
Aşağıdaki kodları single.php'de herhangi bir yere koyduğunuzda resimleriniz art arda görüntülenecektir.
<!--Gallery-->
<div class="photos">
<div class="container">
<h2>Photos</h2>
<div class="row">
<?php
$postData = get_post_meta( get_the_ID() );
$photos_query = $postData['gallery_data'][0];
$photos_array = unserialize($photos_query);
$url_array = $photos_array['image_url'];
$count = sizeof($url_array);
for( $i=0; $i<$count; $i++ ){ ?>
<div class="img_single_box">
<img class="gallery-img" src="<?php echo $url_array[$i]; ?>" alt=""/>
</div>
<?php } ?>
</div>
</div>
</div>
