The value of the post parameter is a path. when it is uploaded to the backend, the backslash is filtered out. how can this problem be solved? Ask rt, the code is as follows $. post (& quot; http: // localhost/gl/index. php? The value of imgUrl = glc/modules/mod_glc_results/ass post parameter is a path. when it is uploaded to the backend, the backslash is filtered out. how can this problem be solved?
Ask rt. the code is as follows:
$. Post ("http: // localhost/gl/index. php? ImgUrl = glc/modules/mod_glc_results/assets/js/flashupload/saved/image/2012061402012-06-14-15-33-34_87618_thumb.jpg "). done (function (){});

$ _ Post ["imgUrl"] in backend php gets a string without a backslash: glcmodulesmod_glc_resultsassetsjsflashuploadsavedimage2012061402012-06-14-15-33-34_87618_thumb.jpg

Ask the elders what knowledge I lack to learn to solve this problem? (In addition, the method of replacing the backslash with special characters has been nearly tested and won't work)

On the JS end, you Urlencode glc/modules/mod_glc_results/assets/js/flashupload/saved/image/2012061402012-06-14-15-33-34_87618_thumb.jpg; otherwise, it will be treated as pathinfo.
