我一直在制作 Joomla 模块。我基本上是成功的，但我有一个问题：如何让image_fulltext变量包含以下内容？
{"image_intro":"","float_intro":"","image_intro_alt":"","image_intro_caption":"","image_fulltext":"images\/sampledata\/parks\/landscape\/800px_cradle_mountain_seen_from_barn_bluff.jpg","float_fulltext":"","image_fulltext_alt":"Konsultasi belajar","image_fulltext_caption":""}
