我有一个为我的网站制作的 WP 前端发布表单,我的想法是让艺术家可以发布他们自己的混音带提交!
到目前为止,我已经设法让表单使用上传的图片作为特色图片,或者给我图片 ID,这样我就可以把它放在帖子内容中,问题是我两者都需要!我需要将图像自动设置为帖子的缩略图,并且我需要 ID,以便我可以将表单设置为自动将图像放在帖子中我想要的位置!
到目前为止,我已经将问题定位为这段代码:
if ($_FILES) {
foreach ($_FILES as $file => $array) {
$newupload = insert_attachment($file,$pid);
// $newupload returns the attachment id
}
}
我这样说,这段代码的位置决定了我是否成功获取附件的 ID 或图像是否设置为缩略图。
整个代码如下:
function insert_attachment($file_handler,$post_id,$setthumb='false') {
// 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, $post_id );
if ($setthumb) update_post_meta($post_id,'_thumbnail_id',$attach_id);
return $attach_id;
}
function mixtape_fep($content = null) {
global $post;
// We're outputing a lot of html and the easiest way
// to do it is with output buffering from php.
ob_start(); ?> <?php
if( 'POST' == $_SERVER['REQUEST_METHOD'] && !empty( $_POST['action'] ) && $_POST['action'] == "new_post") {
// Do some minor form validation to make sure there is content
if (isset ($_POST['title'])) {
$title = $_POST['title'];
} else {
echo 'Please enter the wine name';
}
if (isset ($_POST['description'])) {
$description = $_POST['description'];
} else {
echo 'Please enter some notes';
}
$cover_id = get_post_meta($post->ID, 'thumb', true);
$cover = wp_get_attachment_link($cover_id);
$content = $cover.'<br /><br />'.$description;
$tags = $_POST['post_tags'];
// ADD THE FORM INPUT TO $new_post ARRAY
$new_post = array(
'post_title' => $title,
'post_content' => $content,
'post_category' => array($_POST['cat']), // Usable for custom taxonomies too
'tags_input' => array($tags),
'post_status' => 'publish', // Choose: publish, preview, future, draft, etc.
'post_type' => 'post' //'post',page' or use a custom post type if you want to
);
//SAVE THE POST
$pid = wp_insert_post($new_post);
if ($_FILES) {
foreach ($_FILES as $file => $array) {
$newupload = insert_attachment($file,$pid);
// $newupload returns the attachment id of the file that
// was just uploaded. Do whatever you want with that now.
}
}
//SET OUR TAGS UP PROPERLY
wp_set_post_tags($pid, $_POST['post_tags']);
//REDIRECT TO THE NEW POST ON SAVE
$link = get_permalink( $pid );
wp_redirect( $link );
} // END THE IF STATEMENT THAT STARTED THE WHOLE FORM
//POST THE POST YO
do_action('wp_insert_post', 'wp_insert_post'); ?>
