extract_serialized_parent_block()
云策文档标注
概述
extract_serialized_parent_block() 是一个 WordPress 函数，用于从包含内部块的序列化标记中提取包装块的序列化标记。它通过字符串操作定位并返回包装块部分。
关键要点
- 函数接受一个字符串参数 $serialized_block，表示块及其内部块的序列化标记。
- 返回包装块的序列化标记字符串。
- 使用 strpos() 和 strrpos() 进行字符串定位操作。
- 与 remove_serialized_parent_block() 相关，用于块处理。
- 在 WordPress 6.7.0 版本中引入。
代码示例
function extract_serialized_parent_block( $serialized_block ) {
$start = strpos( $serialized_block, '-->' ) + strlen( '-->' );
$end = strrpos( $serialized_block, '<!--' );
return substr( $serialized_block, $start, $end - $start );
}
原文内容
