  • Ah, well that's the first mystery cleared up. Thank you, Ashley .

  • Update: used a POST request instead, and Firebug comes back with a success, however the database is not updated.

    Changing the default value of the base64 variable to '123' does update the database, which confirms that my PHP file is working.

    It's unclear where the problem is occuring. Perhaps something to do with my data type, or simply the exceedingly long string? (768692 characters in the version generated on the server).

  • Try Construct 3

  • Nope, doesn't seem to be the case. In this instance, I'm not snapshotting the canvas in any case. I'm using Pode's ExtractImage plugin to convert the image to a base64 string, and trying to send this to the db.

    Live (not working) test here: http://dev.angelserver.in/construct2_test/db_test/

    Inspect with Firebug or something to track what's going on.

    So, with this I get a rare 414 error: URI too long! Haven't ever actually seen one of these before. I'm not sure how to handle this. You'll be able to see the length of the base64 string in the Firebug console.

  • Oh my, I just converted a test image (a black and white 512px × 608px PNG) to a base64 string, and it came out at 700,046 characters!

    Is this expected? Is a string this large an appropriate size to be stored in a database? It slowed my browser right down.

  • Thanks — ! I will check it out and see how it goes. If I arrive at a solution using this method, I'll post it here to share it with the community.

    Any ideas why my original execution with AJAX didn't work out, however? I'd still like to know.

  • Wow, just seen this. Following with interest!

  • I did consider this; I've just been exploring my options really. Can you point me in the direction of some resources on this so I can try it out?

    My SQL is alright, but I'm not sure where to start, integrating it into a Construct 2 application thank you — , for your suggestion.

  • Thanks for your reply — Ok, for testing purposes, this is what I'd like to happen:

    1. Click img sprite button

    2. AJAX calls an image file from the server (crucial that I can set this dynamically - it cannot just be a part of the project files)

    3. Upon AJAX load complete, the so-far-empty sprite named 'imgReturnedData' should load the image called by AJAX (LastData).

    For the final app, this will be expanded somewhat:

    1. User creates their user content (in this case, it will be a mugshot generator which they can upload their own photo to. Functionality-only version here: http://www.angelserver.in/html5/mugshot_generator/ )

    2. Upon completion, their image is uploaded to our database using a filename generated within the app

    3. The user might want to share the completed image on Facebook, Twitter etc, so they click on the particular 'share'

    4. AJAX makes a call to our database to retrieve the user-generated image

    5. AJAX.LastData is used to pinpoint the share function to the particular image URL on our database. i.e. Image: "http://our.server/images/" & AJAX.LastData & ".png"

  • Thanks for your reply! Yes, I'm rendering the same result, thanks for confirming it.

    I haven't been able to retrieve an error message that's more meaningful unfortunately, so haven't had much luck in further debugging it

    Am I using the wrong sort of AJAX request? I'm using "Request URL", for which the help text reads "Request a URL by a GET request and retrieve the server response."

  • Thanks, I look forward to it!

  • I'm finding it hard to troubleshoot this issue. Any thoughts?

    I'm testing out the AJAX functionality to implement into a Social sharing feature. I want to retrieve an image from the server (this cannot be just a project file, as the image to retrieve will change so will need to be able to change the URL via a variable.) and for testing purposes, load it into a sprite here. I'll later expand on this to pass the AJAX response to a share plugin in order to post an image to a user's feed/wall/etc.

    In the capx below, the first text version works fine, but the second image version isn't working.

    It appears that the AJAX request has run successfully (as notified by the "SUCCESS!" text), however the image is not being loaded into the sprite using "AJAX.LastData".

    Below is the event sheet.

    Here is a live demo: http://dev.angelserver.in/construct2_test/AJAX_TEST/

  • Ah! Just thought of one additional platform - upload image to Pinterest?

  • Rather than more platforms, for me some additional features would be great?

    The ability to upload an image to Facebook, Twitter and Whatsapp, for example.

    Or the ability to dynamically set which image to upload to any platform (is this already technically possible? I have only just bought the plugin so haven't tested it yet. Something like ' "http://image.url/" + IMGVAR' ?)

    This is all running very smoothly so far though, so thank you.

  • Great!

  • I second Google Plus that would be great!

    It would also be great to be able to post an image to the user's feed/wall/story/whatever.

    How is it going so far?
