In my app I have it so the user can enter in a recipe name, picture and other things and then save it to the app. It saves it a table for the recipe. I so far have been able to save the text the user enters in and it bring it back up in another view in the app, but I am struggling to get it to work with the photo. I have it so the user can select the picture and import it into the app and to save the photo with a custom name but I can’t seem to be able to bring it back up again later to display in the app later. I am storing the photos/photo location in a table. I think my picture somehow gets lost or I don’t have the write filename to access it or something. My picture is saved to the app with its updated name. I can’t seem to get it to display again though.
------Function to save table inside a table--- local function saveRecipeTableToDinnerTable(recipeTable) table.insert(dinnerRecipes,recipeTable) loadsave.saveTable(dinnerRecipes,"recipeData") end -------Function to get the photo and save it to a table---- local function addPhotoOnComplete(event) if (event.completed) then local insertedPhoto=event.target loadsave.loadTable("recipeTable" ) local pictureName={recipeTable.name,".jpg"} media.save(pictureName,system.DocumentsDirectory) local tablePicString={picture=pictureName} local photoNameInsertTable=tablePicString table.insert(recipeTable,photoNameInsertTable) saveRecipeTableToDinnerTable(recipeTable) fitImage(insertedPhoto,400,600) insertedPhoto:translate(100, 400) sceneGroup:insert(insertedPhoto) scrollView:insert(insertedPhoto) local testPic=display.newImageRect(dinnerRecipes[5].picture,system.DocumentsDirectory,400,600) end end ----------------------------------------------------------------------------------------- --------photoListener----------------------------------------------------------- local function addPhotoListener (event) if media.hasSource( media.PhotoLibrary ) then loadsave.loadTable("recipeTable" ) media.selectPhoto( { mediaSource=media.PhotoLibrary, listener = addPhotoOnComplete --destination={baseDir=system.DocumentsDirectory, --filename=recipeTable.name,".jpg"} } ) --media.save("test.jpg",system.DocumentsDirectory) else native.showAlert( "Corona", "This device does not have a photo library.", { "OK" } ) end end -------------------------------------------------------------------------------- --------photoListener----------------------------------------------------------- local function addPhotoListener (event) if media.hasSource( media.PhotoLibrary ) then loadsave.loadTable("recipeTable" ) media.selectPhoto( { mediaSource=media.PhotoLibrary, listener = addPhotoOnComplete --destination={baseDir=system.DocumentsDirectory, --filename=recipeTable.name,".jpg"} } ) --------------------------------------Where I am displaying later----- for i=1, #dinnerRecipes do recipePicture[i] = widget.newButton( { width = 640, height = 300, defaultFile = dinnerRecipes[i].picture,system.DocumentsDirectory or system.ResourceDirectory, id = i, onEvent = goToThisRecipe} ) recipePicture[i]:translate(0, ((i\*tvy)-100)) scrollView:insert(recipePicture[i]) local imageMask=display.newImageRect("darkerMask.png", 640,300) imageMask:translate(320, ((i\*tvy)+50)) scrollView:insert(imageMask) recipeText[i] = display.newText(dinnerRecipes[i].name,320,100,native.systemFontBold,60) recipeText[i]:translate(0,((i\*tvy)-50)) recipeText[i]:setFillColor( 1, 1, 1 ) recipeText[i]:toFront() scrollView:insert(recipeText[i]) print(dinnerRecipes[i].name) end
The table that is saved, that stores the information is
[{“picture”:“tacoSaladPic.png”,“variations”:“Will enter later fishtaco variable”,“recipe”:"1 Cook Hamburger 2 Put chips in … 3… ",“name”:“Taco Salad”,“prepTime”:“20min”,“rating”:3,“cookTime”:“20min”},{“picture”:“hamburger.png”,“variations”:“Will enter later fishtaco variable”,“recipe”:“1 Take ground hamburger and put into patties… 2 Get Bunns…”,“name”:“Hamburger”,“prepTime”:“10 Minutes”,“holiday”:“4th of July”,“cookTime”:“30min”,“ratings”:4},{“picture”:“barnyardBiscuits.jpg”,“variations”:“Will enter later fishtaco variable”,“preptTime”:“20min”,“recipe”:“1 Thaw biscuits 2 put seasoning in hamburger 3… 4…”,“name”:“Barnyard Biscuits”,“rating”:5,“cookTime”:“10min”},{“name”:“Sloppy Joes”,“picture”:“sloppyJoes.jpg”}]
In the simulator it doesn’t supporting photos so it doesn’t go into the saving the function and then doesn’t save the the updated table. I have built the app and ran it and all that showed up was the text entered in.
