前端多文件上传WordPress [英] Front End Multiple File Upload WordPress
问题描述
我正试图允许用户在网站的前端创建事件(自定义帖子类型).一切都在更新,但是我想让他们上传图像并将其附加到该事件的ACF Gallery字段中.
I'm trying to allow users to create an event (custom post type) on the front end of a website. Everything is updating, but I want to let them upload images and attach them to the ACF Gallery field for that event.
所以rar我有这个:
<input type="file" name="upload_attachment[]" class="files" size="50" multiple="multiple" />
和:
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) {
$files = $_FILES['upload_attachment'];
foreach ($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]
);
$attachment_id = media_handle_upload($key, $post_id);
if ( is_wp_error( $attachment_id ) ) {
echo('error <br/>');
} else {
echo('success!<br />');
}
var_dump($attachment_id);
}
}
但是,它似乎不起作用.基本上,我希望将图像上载到媒体库,然后将图像插入到"ACF画廊"字段中.
But, it doesn't seem to be working. Basically I want the image to be uploaded to the media library, and then insert the image into the ACF Gallery Field.
但是我认为第一步是将其放入媒体库中.
But I think the first step is getting it into the media library.
推荐答案
好吧,我设法弄清楚了,以防万一其他人需要做这样的事情.
Okay, I managed figure it out, incase anyone else needs to do something like this.
在前端:
<input type="file" name="upload_attachment[]" class="files" size="50" multiple="multiple" />
<?php wp_nonce_field( 'upload_attachment', 'my_image_upload_nonce' ); ?>
在php文件中,我将表单发布到:
And in the php file I post the form to, I have this:
if (!empty($_FILES['upload_attachment']['name'][0])) {
require_once( ABSPATH . 'wp-admin/includes/image.php' );
require_once( ABSPATH . 'wp-admin/includes/file.php' );
require_once( ABSPATH . 'wp-admin/includes/media.php' );
$files = $_FILES['upload_attachment'];
$count = 0;
$galleryImages = array();
foreach ($files['name'] as $count => $value) {
if ($files['name'][$count]) {
$file = array(
'name' => $files['name'][$count],
'type' => $files['type'][$count],
'tmp_name' => $files['tmp_name'][$count],
'error' => $files['error'][$count],
'size' => $files['size'][$count]
);
$upload_overrides = array( 'test_form' => false );
$upload = wp_handle_upload($file, $upload_overrides);
// $filename should be the path to a file in the upload directory.
$filename = $upload['file'];
// The ID of the post this attachment is for.
$parent_post_id = $post_id;
// Check the type of tile. We'll use this as the 'post_mime_type'.
$filetype = wp_check_filetype( basename( $filename ), null );
// Get the path to the upload directory.
$wp_upload_dir = wp_upload_dir();
// Prepare an array of post data for the attachment.
$attachment = array(
'guid' => $wp_upload_dir['url'] . '/' . basename( $filename ),
'post_mime_type' => $filetype['type'],
'post_title' => preg_replace( '/\.[^.]+$/', '', basename( $filename ) ),
'post_content' => '',
'post_status' => 'inherit'
);
// Insert the attachment.
$attach_id = wp_insert_attachment( $attachment, $filename, $parent_post_id );
// Make sure that this file is included, as wp_generate_attachment_metadata() depends on it.
require_once( ABSPATH . 'wp-admin/includes/image.php' );
// Generate the metadata for the attachment, and update the database record.
$attach_data = wp_generate_attachment_metadata( $attach_id, $filename );
wp_update_attachment_metadata( $attach_id, $attach_data );
array_push($galleryImages, $attach_id);
}
$count++;
// add images to the gallery field
update_field('field_535e6a644107b', $galleryImages, $post_id);
}
}
此脚本现在允许将多个文件上传到服务器,附加到正在创建的帖子中,并添加到"ACF画廊"字段中.
This script now allow multiple files to be uploaded to the server, attached to the post being created and added to the ACF Gallery field.
