Voir ce squelette detéléverseurmultimédia . Vouspouvez également l'utiliser dans votrebalisagepersonnalisé,comme Meta Box.

Unindice,vérifiez que vousn'utilisez que les scripts de lapage où vous activez votre Meta Box. Sinon,c'est souvent unproblème sur lespagespar défautet letéléchargeur.

Essayezmaintenant d'effacer lespartiesimportantespourinclure leprogramme detéléchargement dans votrepartiepersonnalisée.

Commencezparinclure unbouton dans laméta-boîte:

 <input id="upload_image" type="text" size="36" name="upload_image" value="" />
<input id="upload_image_button" type="button" value="Upload Image" />
 

Maintenant,mettez les scriptsen file d'attente:

 function my_admin_scripts() {    
    wp_enqueue_script('media-upload');
    wp_enqueue_script('thickbox');
    wp_register_script('my-upload', WP_PLUGIN_URL.'/my-script.js', array('jquery','media-upload','thickbox'));
    wp_enqueue_script('my-upload');
}

function my_admin_styles() {

    wp_enqueue_style('thickbox');
}

// better use get_current_screen(); or the global $current_screen
if (isset($_GET['page']) && $_GET['page'] == 'my_plugin_page') {

    add_action('admin_print_scripts', 'my_admin_scripts');
    add_action('admin_print_styles', 'my_admin_styles');
}
 

La dernièrepartieest votre scriptpersonnalisépour utiliser la Thickboxet letéléchargeur à l'intérieur.

 jQuery(document).ready( function( $ ) {

    $('#upload_image_button').click(function() {

        formfield = $('#upload_image').attr('name');
        tb_show( '', 'media-upload.php?type=image&TB_iframe=true' );
        window.send_to_editor = function(html) {
           imgurl = $(html).attr('src');
           $('#upload_image').val(imgurl);
           tb_remove();
        }

        return false;
    });

});
 

See this media uploader skeleton. You can also use it in your custom markup, like Meta Box.

A hint, check, that you only use the scripts on the page, where you active your Meta Box. Otherwise is it often a problem on the default pages and the uploader.

Now a attempt to clear the important parts to include the uploader to your custom part.

First include an button in the meta box:

<input id="upload_image" type="text" size="36" name="upload_image" value="" />
<input id="upload_image_button" type="button" value="Upload Image" />

Now enqueue the scripts:

function my_admin_scripts() {    
    wp_enqueue_script('media-upload');
    wp_enqueue_script('thickbox');
    wp_register_script('my-upload', WP_PLUGIN_URL.'/my-script.js', array('jquery','media-upload','thickbox'));
    wp_enqueue_script('my-upload');
}

function my_admin_styles() {

    wp_enqueue_style('thickbox');
}

// better use get_current_screen(); or the global $current_screen
if (isset($_GET['page']) && $_GET['page'] == 'my_plugin_page') {

    add_action('admin_print_scripts', 'my_admin_scripts');
    add_action('admin_print_styles', 'my_admin_styles');
}

The last part is your custom script to use the thickbox and the uploader inside this.

jQuery(document).ready( function( $ ) {

    $('#upload_image_button').click(function() {

        formfield = $('#upload_image').attr('name');
        tb_show( '', 'media-upload.php?type=image&TB_iframe=true' );
        window.send_to_editor = function(html) {
           imgurl = $(html).attr('src');
           $('#upload_image').val(imgurl);
           tb_remove();
        }

        return false;
    });

});

Solution:

1) dans votre functions.php ,ajoutez lebloc d'enregistrement des scriptsnécessaires:

 // add necessary scripts
add_action('plugins_loaded', function(){
  if($GLOBALS['pagenow']=='post.php'){
    add_action('admin_print_scripts', 'my_admin_scripts');
    add_action('admin_print_styles',  'my_admin_styles');
  }
});

function my_admin_scripts(){
  wp_enqueue_script('jquery');
  wp_enqueue_script('media-upload');
  wp_enqueue_script('thickbox');
}

// Proper way to enqueue
// wp_register_script(
//   'my-upload',
//   WP_PLUGIN_URL.'/my-script.js',
//   array('jquery','media-upload','thickbox') /* dependencies */
// );
//
// wp_enqueue_script('my-upload');

function my_admin_styles(){
  wp_enqueue_style('thickbox');
}
 

2)puis ajoutez lebloc metabox :

 add_action(
  'add_meta_boxes',
  function(){
    add_meta_box(
      'my-metaboxx1', // ID
      'my-metaboxx1-title', // Title
      'func99999', // Callback (Construct function)
      get_post_types(), //screen (This adds metabox to all post types)
      'normal' // Context
    );
 },
 9
);
function func99999($post){
  $url = get_post_meta($post->ID, 'my-image-for-post', true); ?>
  <input id="my_image_URL" name="my_image_URL" type="text"
         value="<?php echo $url;?>" style="width:400px;" />
  <input id="my_upl_button" type="button" value="Upload Image" /><br/>
  <img src="<?php echo $url;?>" style="width:200px;" id="picsrc" />
  <script>
  jQuery(document).ready( function($) {
    jQuery('#my_upl_button').click(function() {
      window.send_to_editor = function(html) {
        imgurl = jQuery(html).attr('src')
        jQuery('#my_image_URL').val(imgurl);
        jQuery('#picsrc').attr("src", imgurl);
        tb_remove();
      }

      formfield = jQuery('#my_image_URL').attr('name');
      tb_show('', 'media-upload.php?type=image&amp;TB_iframe=true' );
      return false;
    }); // End on click
  });
  </script>
<?php
}

add_action('save_post', function ($post_id) {
  if (isset($_POST['my_image_URL'])){
    update_post_meta($post_id, 'my-image-for-post', $_POST['my_image_URL']);
  }
});
 

p.s. au cas où vous auriezbesoin deplusieurs champs,vouspouvezfacilementfaire comme ceci: http://pastebin.com/raw/xpU1ch2W

Solution:

1) in your functions.php, add the block for registering the necessary scripts:

// add necessary scripts
add_action('plugins_loaded', function(){
  if($GLOBALS['pagenow']=='post.php'){
    add_action('admin_print_scripts', 'my_admin_scripts');
    add_action('admin_print_styles',  'my_admin_styles');
  }
});

function my_admin_scripts(){
  wp_enqueue_script('jquery');
  wp_enqueue_script('media-upload');
  wp_enqueue_script('thickbox');
}

// Proper way to enqueue
// wp_register_script(
//   'my-upload',
//   WP_PLUGIN_URL.'/my-script.js',
//   array('jquery','media-upload','thickbox') /* dependencies */
// );
//
// wp_enqueue_script('my-upload');

function my_admin_styles(){
  wp_enqueue_style('thickbox');
}

2) and then add metabox block:

add_action(
  'add_meta_boxes',
  function(){
    add_meta_box(
      'my-metaboxx1', // ID
      'my-metaboxx1-title', // Title
      'func99999', // Callback (Construct function)
      get_post_types(), //screen (This adds metabox to all post types)
      'normal' // Context
    );
 },
 9
);
function func99999($post){
  $url = get_post_meta($post->ID, 'my-image-for-post', true); ?>
  <input id="my_image_URL" name="my_image_URL" type="text"
         value="<?php echo $url;?>" style="width:400px;" />
  <input id="my_upl_button" type="button" value="Upload Image" /><br/>
  <img src="<?php echo $url;?>" style="width:200px;" id="picsrc" />
  <script>
  jQuery(document).ready( function($) {
    jQuery('#my_upl_button').click(function() {
      window.send_to_editor = function(html) {
        imgurl = jQuery(html).attr('src')
        jQuery('#my_image_URL').val(imgurl);
        jQuery('#picsrc').attr("src", imgurl);
        tb_remove();
      }

      formfield = jQuery('#my_image_URL').attr('name');
      tb_show('', 'media-upload.php?type=image&amp;TB_iframe=true' );
      return false;
    }); // End on click
  });
  </script>
<?php
}

add_action('save_post', function ($post_id) {
  if (isset($_POST['my_image_URL'])){
    update_post_meta($post_id, 'my-image-for-post', $_POST['my_image_URL']);
  }
});

p.s. in case you need multiple fields, then you can easily do like this: http://pastebin.com/raw/xpU1ch2W
