尝试在路径中使用$ value来移动基于此php文件的文件

Question

I am trying to get the file to upload an image or audio file to the following directory

$dir='sites/default/documents/"$patientID"/' but I don't know how to use the exact syntax with the $ sign inside a path.

I used the get method to get the patientID from the controller but still nothing is working

Answer 1

Use this instead : $dir="sites/default/documents/$patientID/";

In your case the variable is considered as a text.
