Question

我正在使用wordpress的前端表单来创建自定义帖子类型并上传附加到该帖子的图片。

以下是我的代码。帖子已创建，但问题是图片未上传到附加到该帖子的服务器。另一方面，我希望在发送表单之前预先显示图像，就像wordpress适用于管理区域一样。

public class ProfileActivity extends AppCompatActivity implements View.OnClickListener {

public static final String JSON_URL = "/*I ommitted my URL on purpose here*/";
private TextView username_txt;
private Button fetch_data_btn;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_profile);

    username_txt = (TextView)findViewById(R.id.txt_username);
    fetch_data_btn = (Button)findViewById(R.id.btn_fetch_data);

    SharedPreferences sharedPreferences = getSharedPreferences(Config.SHARED_PREF_NAME, Context.MODE_PRIVATE);
    String username = sharedPreferences.getString(Config.USERNAME_SHARED_PREF,"Not Available");

    username_txt.setText(username);
    sendRequest();
    fetch_data_btn.setOnClickListener(this);
}

private void sendRequest(){
    final ProgressDialog loading = ProgressDialog.show(this,"Fetching data.","Please wait...", false,false);
    StringRequest stringRequest = new StringRequest(Request.Method.GET,JSON_URL,
            new Response.Listener<String>() {
                @Override
                public void onResponse(String response) {
                    System.out.println(response.substring(0));
                    showJSON(response);
                }
            },
            new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError error) {
                    System.out.println("Something went wrong!");
                    Toast.makeText(ProfileActivity.this, "Something went wrong!", Toast.LENGTH_LONG).show();
                }
            });
    RequestQueue requestQueue = Volley.newRequestQueue(this);
    requestQueue.add(stringRequest);
}

private void showJSON(String json){
    ParseWorkOrderJSON pwoj = new ParseWorkOrderJSON();
    pwoj.parseWorkOrderJSON(json);

}
@Override
public void onClick(View v){
    sendRequest();
    Intent intent = new Intent(ProfileActivity.this, MytabActivity.class);
    startActivity(intent);
}

}

形式：

if ( 'POST' == $_SERVER['REQUEST_METHOD'] && !empty( $_POST['new_cpt_action'] ) &&  $_POST['new_cpt_action'] == "new_cpt" && isset( $_POST['new_cpt-form'] ) && wp_verify_nonce( $_POST['new_cpt-form'], 'create_new_cpt' ) ){

if (isset($_POST['submit'])) {
    $error = "";
    if (!empty($_POST['s_name'])) {
        $s_name =  $_POST['s_name'];
    } else {
        $error = 'Please insert a name';
    }
    if (empty($error)) {
        $new_post = array(
        'post_title'    =>  $s_name,
        'post_status'   =>  'pending', 
        'post_type' =>  'my_cpt',  
        );

        //Save the post
        $post_id = wp_insert_post($new_post);

        if( ! empty( $_FILES ) ) {
            foreach( $_FILES as $file ) {
                if( is_array( $file ) ) {
                    $attachment_id = wp_insert_attachment($file, $post_id);
                }
            }
        }

        //Redirect to the new post
        if ( $post_id ) {
                wp_redirect(home_url('site/'.$post_id));
            exit;
        }
    }
}

如果可以，请告诉我我错过的内容会很棒。感谢

我设法使用以下代码将附件包含在wp媒体库中：

if ( $_FILES ) { 
                $files = $_FILES["file"];  
                foreach ($files['name'] as $key => $value) {            
                        if ($files['name'][$key]) { 
                            $file = array( 
                                'name' => $files['name'][$key],
                                'type' => $files['type'][$key], 
                                'tmp_name' => $files['tmp_name'][$key], 
                                'error' => $files['error'][$key],
                                'size' => $files['size'][$key]
                            ); 
                            $_FILES = array ("file" => $file); 
                            foreach ($_FILES as $file => $array) {              
                                $newupload = frontend_handle_attachment( $file, $post_id ); 
                            }
                        } 
                    } 
                }

调用函数frontend_handle_attachment：

function frontend_handle_attachment($file_handler,$post_id) {
// check to make sure its a successful upload
if ($_FILES[$file_handler]['error'] !== UPLOAD_ERR_OK) __return_false();

require_once(ABSPATH . "wp-admin" . '/includes/image.php');
require_once(ABSPATH . "wp-admin" . '/includes/file.php');
require_once(ABSPATH . "wp-admin" . '/includes/media.php');

$attach_id = media_handle_upload( $file_handler, $post_id );

// Set featured image 
set_post_thumbnail($post_id, $attach_id);
return $attach_id;
}

这可以通过以下形式的简单输入正常工作：

<input type="file" name="file[]" multiple="multiple" />

至于图像的进度条和预可视化，我试图实现dropzone，但到目前为止还没有运气。至少这种简单的方法是有效的。
