Question

我正在开发一个插件，用户可以使用功能图片提交帖子。但是，要素图像设置为发布但不上传到目录。

HTML输入字段

<form id="fep-new-post" name="new_post" method="post" action="" enctype="multipart/form-data">
            <input placeholder="Add Post Title" type="text" id ="fep-post-title" name="post-title"/>
            <p>
            <?php 
            $settings = array(
            'textarea_rows' => 12,
            'teeny' => false,
            'quicktags' => false,
            'textarea_name' => 'post-content',
            'media_buttons' => true,
            'editor_class' => 'front-end-post',
            'tinymce' => array(
                'theme_advanced_buttons1' => 'formatselect,|,bold,italic,underline,|,' .
                    'bullist,blockquote,|,justifyleft,justifycenter' .
                    ',justifyright,justifyfull,|,link,unlink,|' .
                    ',spellchecker,wp_fullscreen,wp_adv'
                )
            );
            wp_editor( '', 'content', $settings);
            ?>
            </p>
            <p>

                <select id="user_submitted_categories"  name="post-category"> 
                 <option value="<?php null ?>">Select category</option> 
                 <?php 
                  $categories = get_categories(); 
                  foreach ($categories as $category) {
                    $option = '<option value="'.$category->cat_ID.'">';
                    $option .= $category->cat_name;
                    $option .= '</option>';
                    echo $option;
                  }
                 ?>
            </select>
            </p>
    <input type="file" name="my_image_upload" id="my_image_upload"  multiple="false" />
            <p><input id="fep-tags" name="tags" type="text" tabindex="2" autocomplete="off" placeholder="Add Post tag"/></p>
            <input class="button" onclick="requiredInput()" id="submit" type="submit" tabindex="3" value="<?php esc_attr_e( 'Publish', 'exclutips-fep' ); ?>" />                    
            <input type="hidden" name="action" value="post" />
            <input type="hidden" name="empty-description" id="empty-description" value="1"/>
            <?php wp_nonce_field( 'new-post' ); ?>
        </form>

PHP

    $post_id = wp_insert_post( array(
                    'post_author'   => $user_id,
                    'post_title'    => $post_title,
                    'post_type'     => 'post',
                    'post_content'  => $post_content,
                    'post_category' => $post_category,
                    'tags_input'    => $tags,
                    'post_status'   => 'publish'
                    ) );    

   $uploaddir = wp_upload_dir();
            $post_image     = $_POST['my_image_upload'];

            $uploadfile = $uploaddir['path'] . '/' . basename( $post_image);

            move_uploaded_file( $post_image, $uploadfile );
            $filename = basename( $uploadfile );

            $wp_filetype = wp_check_filetype(basename($filename), null );

            $attachment = array(
                'guid'           => $uploaddir['url'] . '/' . basename( $filename ), 
                'post_mime_type' => $wp_filetype['type'],
                'post_title'     => preg_replace( '/\.[^.]+$/', '', basename( $filename ) ),
                'post_content'   => '',
                'post_status'    => 'inherit'
            );
            $attach_id = wp_insert_attachment( $attachment, $uploadfile, $post_id );

            set_post_thumbnail( $post_id, $attach_id );

Answer 1

我们在这里处理文件而不是（文本）输入。

因此，您需要将$_POST['my_image_upload']更改为$_FILES['my_image_upload']

根据您的文件表单元素：

<input type="file" name="my_image_upload" id="my_image_upload"  multiple="false" />

参考：

http://php.net/manual/en/features.file-upload.post-method.php

另外，请确保您要上传的文件夹具有写入该文件夹的正确权限。

将error reporting添加到文件的顶部，这有助于查找错误。

旁注：只应在暂存时进行显示错误，而不是生产。

$post_id = wp_insert_post( array(
            'post_author'   => $user_id,
            'post_title'    => $post_title,
            'post_type'     => 'post',
            'post_content'  => $post_content,
            'post_category' => $post_category,
            'tags_input'    => $tags,
            'post_status'   => 'publish'
            ) );            

        //=============================================================
        $uploaddir = wp_upload_dir();
        $file = $_FILES['my_image_upload'];
        $uploadfile = $uploaddir['path'] . '/' . basename( $file['name'] );

        move_uploaded_file( $file['tmp_name'] , $uploadfile );
        $filename = basename( $uploadfile );

        $wp_filetype = wp_check_filetype(basename($filename), null );

        $attachment = array(
            'post_mime_type' => $wp_filetype['type'],
            'post_title' => preg_replace('/\.[^.]+$/', '', $filename),
            'post_content' => '',
            'post_status' => 'inherit'
        );
        $attach_id = wp_insert_attachment( $attachment, $uploadfile );

        set_post_thumbnail( $post_id, $attach_id );

Answer 2

我看不到你的表格，所以我只能猜一猜。

您的表单上可能缺少 enctype 属性（enctype =“multipart / form-data”）。如果您想要上传图片，则需要这样做。

如果您的表单中有 enctype 属性，请忽略此答案，但也请在此处发布您的HTML，以便我们了解正在发生的事情！
