I own a jQuery mobile website. There i using facebook share option with custom parameters to add title, description, image with link
But when i try the same link to mobile, it will redirect to http://m.facebook.com/sharer.php?s=100&p%5Burl%5D=http%3A%2F%2Fgoogle%2F&p%5Bimages%5D%5B0%5D=https%3A%2F%2Fwww.google.com%2Fimages%2Fsrpr%2Flogo3w.png&p%5Btitle%5D=My+own+title&p%5Bsummary%5D=My+own+description&_rdr
which means, it will add m.facebook at the start of share url. so it wont work with custom title, desc, image & link.
Anyway to fix this? or how to force mobile web to not to go with m.facebook.com ?
You can prevent Facebook from going to the mobile site by adding a ?m2w parameter to the URL. Then, sharer.php works like usual.
e.g.
https://www.facebook.com/sharer/sharer.php?m2w&s=100.... (etc)
Looks kind of bad though, looking for a better answer.
Edit: Sharer.php has been deprecated, see Felix' answer below.
sharer.php has now been deprecated. https://developers.facebook.com/bugs/252983554810810/
The new method is to use the share dialog: https://developers.facebook.com/docs/sharing/reference/share-dialog
e.g.
https://www.facebook.com/dialog/share?
app_id=145634995501895
&display=popup
&href=https%3A%2F%2Fdevelopers.facebook.com%2Fdocs%2F
&redirect_uri=https://developers.facebook.com/tools/explorer
url for mobile is supported as u, and title is supported as t
http://m.facebook.com/sharer.php?u=<urlencoded url>&t=<urlencoded title>
Use the mobile url to fix the problem in mobile devices, Facebook will redirect to the share dialog in desktop.
http://m.facebook.com/sharer.php?u=<urlencoded url>
