After too much of hard work and research and some customization I coded below compact few lines of code to use media uploader anywhere in wordpress. Just put code in some function and call that function wherever you want. The path of uploaded/selected file will be copied to text-box and then you can use it.
Hope this helps someone.!
// jQuery wp_enqueue_script('jquery'); // This will enqueue the Media Uploader script wp_enqueue_media(); ?> <div> <label for="image_url">Image</label> <input type="text" name="image_url" id="image_url" class="regular-text"> <input type="button" name="upload-btn" id="upload-btn" class="button-secondary" value="Upload Image"> </div> <script type="text/javascript"> jQuery(document).ready(function($){ $('#upload-btn').click(function(e) { e.preventDefault(); var image = wp.media({ title: 'Upload Image', // mutiple: true if you want to upload multiple files at once multiple: false }).open() .on('select', function(e){ // This will return the selected image from the Media Uploader, the result is an object var uploaded_image = image.state().get('selection').first(); // We convert uploaded_image to a JSON object to make accessing it easier // Output to the console uploaded_image console.log(uploaded_image); var image_url = uploaded_image.toJSON().url; // Let's assign the url value to the input field $('#image_url').val(image_url); }); }); }); </script> UPDATE: Just to add. You may need to add the function wrapper in your plugin/theme file. This is the following:
// UPLOAD ENGINE function load_wp_media_files() { wp_enqueue_media(); } add_action( 'admin_enqueue_scripts', 'load_wp_media_files' ); This will call the relevant JS files and CSS files if WP fails to load the upload manager. This also removes console warnings.

I'm using this method to use media uploader into my custom plugin.May be this would be help.
in the main theme file(index.php) add these.
wp_enqueue_style('thickbox'); // call to media files in wp wp_enqueue_script('thickbox'); wp_enqueue_script( 'media-upload'); // load script to admin function wpss_admin_js() { $siteurl = get_option('siteurl'); $url = $siteurl . '/wp-content/plugins/' . basename(dirname(__FILE__)) . '/js/admin_script.js'; echo "<script type='text/javascript' src='$url'></script>"; } add_action('admin_head', 'wpss_admin_js');
In the admin_script.js file,
jQuery('#wpss_upload_image_button').click(function() { formfield = jQuery('#wpss_upload_image').attr('name'); tb_show('', 'media-upload.php?type=image&TB_iframe=true'); return false; }); window.send_to_editor = function(html) { imgurl = jQuery('img',html).attr('src'); jQuery('#wpss_upload_image').val(imgurl); tb_remove(); jQuery('#wpss_upload_image_thumb').html("<img height='65' src='"+imgurl+"'/>"); } admin file(admin_settings.php),
<div id="wpss_upload_image_thumb" class="wpss-file"> <?php if(isset($record->security_image) && $record->security_image !='') { ?> <img src="<?php echo $record->security_image;?>" width="65"/><?php } else { echo $defaultImage; } ?> </div> <input id="wpss_upload_image" type="text" size="36" name="wpss_upload_image" value="" class="wpss_text wpss-file" /> <input id="wpss_upload_image_button" type="button" value="Upload Image" class="wpss-filebtn" /> More details in my blog

Use this in your custom plugin
<label for="upload_image"> <input id="upload_image" type="text" size="36" name="ad_image" value="http://" /> <input id="upload_image_button" class="button" type="button" value="Upload Image" /> <br />Enter a URL or upload an image </label> <?php add_action('admin_enqueue_scripts', 'my_admin_scripts'); function my_admin_scripts() { if (isset($_GET['page']) && $_GET['page'] == 'my_plugin_page') { wp_enqueue_media(); wp_register_script('my-admin-js', WP_PLUGIN_URL.'/my-plugin/my-admin.js', array('jquery')); wp_enqueue_script('my-admin-js'); } } ?> <script> jQuery(document).ready(function($){ var custom_uploader; $('#upload_image_button').click(function(e) { e.preventDefault(); //If the uploader object has already been created, reopen the dialog if (custom_uploader) { custom_uploader.open(); return; } //Extend the wp.media object custom_uploader = wp.media.frames.file_frame = wp.media({ title: 'Choose Image', button: { text: 'Choose Image' }, multiple: true }); //When a file is selected, grab the URL and set it as the text field's value custom_uploader.on('select', function() { console.log(custom_uploader.state().get('selection').toJSON()); attachment = custom_uploader.state().get('selection').first().toJSON(); $('#upload_image').val(attachment.url); }); //Open the uploader dialog custom_uploader.open(); }); }); </script> 来源：https://stackoverflow.com/questions/17668899/how-to-add-the-media-uploader-in-wordpress-plugin
