boen_robot Posted January 13, 2011 Share Posted January 13, 2011 Hmmmm....I don't really want to see a download box. The json output will be echo'd back to anotherapplication that will parse out the needed info.Either way - the other application will receive the text just fine. Try it in that other application (assuming you have access to it). The download box is only displayed when you manually open that URL, because the browser doesn't know how to visualize JSON. The other app however doesn't need to visualize it - it needs to read it, and it can do that. Link to comment Share on other sites More sharing options...

thescientist Posted January 13, 2011 Share Posted January 13, 2011 validating your JSON might be helpful for debugging as well.http://www.jsonlint.com Link to comment Share on other sites More sharing options...
boen_robot Posted January 13, 2011 Share Posted January 13, 2011 Opps... my bad... it's header('Content-Type: application/json'); (note the "n" in "Content")BTW JSONLint shows a syntax error in your code about a "{" that follows a "}", i.e. "}{"... you can only send one JSON object at once. If you need to encode several objects into one response, you'll have to first place the objects in an array, and json_encode() the array. Link to comment Share on other sites More sharing options...
rayj00 Posted January 13, 2011 Author Share Posted January 13, 2011 validating your JSON might be helpful for debugging as well.http://www.jsonlint.com The errored line is 146 which is the line where the duplicate json begins.Still confused as to why I am seeing this.And fixing the "Content", I now am seeing the file save box.Ray Link to comment Share on other sites More sharing options...
boen_robot Posted January 13, 2011 Share Posted January 13, 2011 The errored line is 146 which is the line where the duplicate json begins.Still confused as to why I am seeing this.How does your PHP file look in its entirety? Are you sure you aren't outputting the whole thing twice somehow?And fixing the "Content", I now am seeing the file save box.file save box === file download boxYes, this is to be expected.

Are you sure you aren't outputting the whole thing twice somehow?file save box === file download boxYes, this is to be expected.Ok, the json now validates with the "header('Content-Type: application/json');" before the echo.(without the header, it does not validate).I still get the save file request. I'm not sure how the app is going to react to this.It may be awhile until I'm at the point to actually test this with the appas I need to do some upfront work as well as figuring out how to parse out what I need, when I need it, where I need it, etc.I will keep you guys informed if you want.Again. Thanks a ton for all the help!Ray Link to comment Share on other sites More sharing options...
boen_robot Posted January 13, 2011 Share Posted January 13, 2011 In what language is the receiving app written?Whatever the case, the way to parse it is sure to be some of the corresponding APIs somewhere on the bottom of JSON's home page. And stop worrying about if it will read it - it WILL. Try it for goodness' sake! Link to comment Share on other sites More sharing options...

One error showed an extra double quote mark.Thanks,Ray Link to comment Share on other sites More sharing options...
justsomeguy Posted January 18, 2011 Share Posted January 18, 2011 If the JSON structure is not valid then the code which generates it is not correct. Link to comment Share on other sites More sharing options...

justsomeguy Posted January 19, 2011 Share Posted January 19, 2011 It should be handling that stuff automatically. I think we're going in circles, but what is in $xml? I'm wondering if those are actual quotes or if they are entities that get decoded along the way or something and don't get escaped. Link to comment Share on other sites More sharing options...

justsomeguy Posted January 20, 2011 Share Posted January 20, 2011 According to the XML output at the commented URL, it is using " for the quotes. I'm not sure why those are automatically being replaced with regular quotes, or why json_encode would not escape the quotes. Link to comment Share on other sites More sharing options...
boen_robot Posted January 20, 2011 Share Posted January 20, 2011 Are you reading the file or the text output again?When the dialog box appears, you must save the file and view it with Notepad. Is it all OK at that point?If you're uncommenting the header line to see what's going on, the text will be treated as HTML, at which points escaped quotes will be displayed as is, making you think what you're thinking.
