Server JSON error when mbtiles file contains a legend

[VNuhaan]

Dear Klokantech,

I have two mbtile files, one with a legend the other without a legend. When I put the one with the legend in the tile server directory, I get a JSON server error. I deleted the legend from the mbtile file. Put this modified file in the tile server directory and everything works. Can you change the tileserver.php so it can also serve mbtile files with a legend?

With best regards,

Vincent

Thanks for the report. Can you provide us a file with not working legend?

Hereby I sent you a small mbtile file with the legend. I hope you can fix the server so that it can use any legend.

Best regards,

Vincent

I didn't receive file but tileserver-php serving legend correctly. See: http://labs.klokantech.com/tileserver-php/geography-class.json You have to modify your viewer to see a legend.

I sent the file via email, that didn't work. So hereby I attach it to the post. It worked with the tile server from infostreams.

Rename extension to mbtiles

I found the 'problem'. The legend I create uses ' (quote). I replaced them with " (double quotation mark). It looks like the quote is a special character. Are there more special characters which you can not use in a legend?

[daliborjanak]

There is PHP json_decode (http://php.net/manual/en/function.json-decode.php) which is escaping special characters. You cannot use characters which are not allowed unescaped in JSON format.
