第16行是

path="files[userid=1]/originalname/folder/description/source/thumbnail";

如果这是PHP代码，您需要在

路径

之前使用

该行下面的代码似乎是Javascript。因此，您可能应该使用如下语法将PHP变量$path传递到Javascript中：

var path = "<?=$path ?>";

var path=”“；

嗯,

您好，非常感谢。我必须承认，我在这里有点深不可测，因为我不确定除了我已经有的脚本之外，我还需要包括什么。我最初包含的代码来自我一直在学习的一个教程。我刚刚尝试使用了以下行

$path=“files[userid=1]/originalname/folder/description/source/thumbnail”解析错误：语法错误，在/homepages/2/d33603417/htdocs/development/gallery.php的第16行

，第16行是xpath行。你能告诉我哪里出了问题吗。问候
path="files[userid=1]/originalname/folder/description/source/thumbnail";

var path = "<?=$path ?>";
