Php 显示响应状态-使用JQuery上载图像

我想做的是从URL下载一些图片，然后上传到WordPress post，我的表格如下：

<form method="post" id="upload">
<?php foreach($data as $row): ?>

<label>File Name</label>
<input type="text" id="filename_<?php echo $row->id;?>" name="data[<?php echo $row->id;?>][filename]" value="<?php echo $file_name;?>" />

<label>Title</label>
<input type="text" id="title_<?php echo $row->id;?>" name="data[<?php echo $row->id;?>][title]" value="<?php echo $title;?>" />

<?php endforeach;?> 
<button name="act" value="savepost">Save</button>
</form>
<!-- showing result here -->
<div id="result"></div>

如何使用jquery在单击保存按钮时显示响应结果。

将您的img附加到html

像

$（$post）.each（函数（）{
$（“#您想要显示的位置ID”）。附加（“”）
})

将您的img附加到html

像

$（$post）.each（函数（）{
$（“#您想要显示的位置ID”）。附加（“”）
})

确保表单具有enctype=“多部分/表单数据”属性

$new_post = wp_insert_post($post_array);
if (!function_exists('wp_generate_attachment_metadata')){
                require_once(ABSPATH . "wp-admin" . '/includes/image.php');
                require_once(ABSPATH . "wp-admin" . '/includes/file.php');
                require_once(ABSPATH . "wp-admin" . '/includes/media.php');
            }
             if ($_FILES) {
                foreach ($_FILES as $file => $array) {
                    if ($_FILES[$file]['error'] !== UPLOAD_ERR_OK) {
                        return "upload error : " . $_FILES[$file]['error'];
                    }
                    $attach_id = media_handle_upload( $file, $new_post );
                }   
            }
            if ($attach_id > 0){

                update_post_meta($new_post,'_thumbnail_id',$attach_id);
            }

确保表单具有enctype=“multipart/form data”属性

$new_post = wp_insert_post($post_array);
if (!function_exists('wp_generate_attachment_metadata')){
                require_once(ABSPATH . "wp-admin" . '/includes/image.php');
                require_once(ABSPATH . "wp-admin" . '/includes/file.php');
                require_once(ABSPATH . "wp-admin" . '/includes/media.php');
            }
             if ($_FILES) {
                foreach ($_FILES as $file => $array) {
                    if ($_FILES[$file]['error'] !== UPLOAD_ERR_OK) {
                        return "upload error : " . $_FILES[$file]['error'];
                    }
                    $attach_id = media_handle_upload( $file, $new_post );
                }   
            }
            if ($attach_id > 0){

                update_post_meta($new_post,'_thumbnail_id',$attach_id);
            }
