我的自定义帖子类型缩略图似乎工作正常。

然而，当我返回编辑我的一个物种配置文件时（在管理区域，这里不谈前端），以下文本直接在我的元框中的特征图像上方涂鸦：

Notice: Uninitialized string offset: 0 in /home/my/domain/public-facing.com/public_html/wp-includes/media.php on line 537

我知道我可以通过更改WP_DEBUG 但我不愿意在现阶段这样做（仍在开发CMS）。

EDIT

我用来实现此功能的唯一代码是我插件中的这一行：

\'supports\' => array(\'author\',\'thumbnail\',\'excerpt\',\'comments\')

.. 这一行在我的主题功能中。php：

add_theme_support( \'post-thumbnails\', array( \'post\', \'species\' ) );

该错误实际上也发生在“我的媒体库”页面上：

这是来自的代码media.php. 第537至550行。

    if ( ( $data[\'width\'] == $size[0] && $data[\'height\'] <= $size[1] ) || ( $data[\'height\'] == $size[1] && $data[\'width\'] <= $size[0] ) ) {
        $file = $data[\'file\'];
        list($width, $height) = image_constrain_size_for_editor( $data[\'width\'], $data[\'height\'], $size );
        return compact( \'file\', \'width\', \'height\' );
    }
    // add to lookup table: area => size
    $areas[$data[\'width\'] * $data[\'height\']] = $_size;
}
if ( !$size || !empty($areas) ) {
    // find for the smallest image not smaller than the desired size
    ksort($areas);
    foreach ( $areas as $_size ) {
        $data = $imagedata[\'sizes\'][$_size];
        if ( $data[\'width\'] >= $size[0] || $data[\'height\'] >= $size[1] ) {

当我不使用字符串格式时，也会出现此错误<?php the_post_thumbnail( \'indexleft-species-thumb\' ); ?>. 如果我使用<?php the_post_thumbnail( array(200,200) ); ?> 它将显示与上述相同的错误。

有什么想法吗？
提前感谢，

foreach ( $imagedata[\'sizes\'] as $_size => $data)
    {
        if ( is_array($data) ) {
      // already cropped to width or height; so use this size
            if ( ( $data[\'width\'] == $size[0] && $data[\'height\'] <= $size[1] ) || ( $data[\'height\'] == $size[1] && $data[\'width\'] <= $size[0] ) ) {
