我的wordpress插件中包含了一个wordpress媒体选择器。
i got this error:
Unable to create directory wp-content/uploads/2022/12. Is its parent directory writable by the server?
误差
我将此代码添加到wp-config.php文件中:
/** WordPress değişkenlerini ve yollarını kurar. */
require_once ABSPATH . 'wp-settings.php';
define( 'UPLOADS', 'wp-content/uploads' );
并添加到myportfolio-form.php文件
<?php
add_action( 'admin_footer', 'media_selector_print_scripts' );
function media_selector_print_scripts() {
$my_saved_attachment_post_id = get_option( 'media_selector_attachment_id', 0 );
?><script type='text/javascript'>
jQuery( document ).ready( function( $ ) {
// Uploading files
var file_frame;
var wp_media_post_id = wp.media.model.settings.post.id; // Store the old id
var set_to_post_id = <?php echo $my_saved_attachment_post_id; ?>; // Set this
jQuery('#upload_image_button').on('click', function( event ){
event.preventDefault();
// If the media frame already exists, reopen it.
if ( file_frame ) {
// Set the post ID to what we want
file_frame.uploader.uploader.param( 'post_id', set_to_post_id );
// Open frame
file_frame.open();
return;
} else {
// Set the wp.media post id so the uploader grabs the ID we want when initialised
wp.media.model.settings.post.id = set_to_post_id;
}
// Create the media frame.
file_frame = wp.media.frames.file_frame = wp.media({
title: 'Select a image to upload',
button: {
text: 'Use this image',
},
multiple: false // Set to true to allow multiple files to be selected
});
// When an image is selected, run a callback.
file_frame.on( 'select', function() {
// We set multiple to false so only get one image from the uploader
attachment = file_frame.state().get('selection').first().toJSON();
// Do something with attachment.id and/or attachment.url here
$( '#image-preview' ).attr( 'src', attachment.url ).css( 'width', 'auto' );
$( '#image_attachment_id' ).val( attachment.id );
// Restore the main post ID
wp.media.model.settings.post.id = wp_media_post_id;

// Finally, open the modal
file_frame.open();

我试图将wordpress媒体选择器包含到我的插件中，但它不起作用。
错误:无法创建目录wp-content/uploads/2022/12。它的父目录是否可以被服务器写入?
您需要更改服务器本身的目录权限
- chmod -R 777/path/to/web-root/wp-content/uploads
(以Linux为例，这将改变所有文件)
- chmod 777/path/to/web-root/wp-content
(这将只改变目录本身，而不是所有文件)
