I'm trying to insert product_name, product_quantity and price into a database via ajax and php. This is my code so far. It does work with product name but I can't get it working including product price and quantity for each one of the product names . This code is throwing the error console.error('Fetch error:', error); $jsonInput = file_get_contents('php://input'); $decodedData = json_decode($jsonInput, true); if (!isset($decodedData['items']) || !is_array($decodedData['items'])) { echo json_encode(['status' => 'error', 'message' => 'Invalid or missing array data']); exit; } $itemsArray = $decodedData['items']; // 3. Prepare SQL query to prevent SQL Injection $stmt = $conn->prepare("INSERT INTO shopping_carts_quotes (product_name) VALUES (?)");

Example data: ID<-c("A","A","A","A","A","A","B","B","B") HFAdmission<-c("2020-01-01", "2020-02-01", "2020-03-01", NA, NA, NA, "2020-06-01", "2020-07-01", NA) link_type<-c("Linked", "HF only", "HF only", "HES only", "HES only", "HES only", "Linked", "HF only", "HES only") ADMIDATE<-c(NA,NA,NA,"2020-03-01","2020-04-01","2020-05-01",NA,NA, "2020-07-01") newdate<-c(NA, "2020-02-01", "2020-03-01", "2020-03-01","2020-04-01","2020-05-01", NA, "2020-07-01", "2020-07-01") df<-data.frame(ID, HFAdmission,link_type,ADMIDATE,newdate) as.Date(df$HFAdmission) as.Date(df$ADMIDATE) as.Date(df$newdate) df should look

“I have marked the Previous Day Low line. Now, on any timeframe, if any candle breaks that low line, I want to draw a new horizontal line at the low of that breakout candle. The new line should extend only to the right side, and only the first breakout candle should be marked — not every candle below the level.”

Introduction I've been developing software very successfully for many years. The reason I have chosen this profession is multifold: I'm a creative person and I need to create things I have an insatiable drive to think Financial compensation one may expect for doing this I can do my thing without constantly socializing with superficial small-talk The drive to solve real-world problems and to be a force for the better To work from home It has been a great ride to do this and I achieved quite a lot of things. Yet, the industry gradually deteriorated. I do know that sometimes libraries and APIs are needed, but I witnessed too many times the drive to use some library only to solve some problem we could have otherwise easily solved, which to me meant that the specific decision was "going with the vibes" rather than a rational choice. Sure thing, there

I'm using Compose Multiplatform on iOS and embedding a ComposeUIViewController inside SwiftUI. My hierarchy is: SwiftUI ScrollView └── UIViewControllerRepresentable └── ComposeUIViewController Example : struct ComposeContainer: UIViewControllerRepresentable { let factory: () -> UIViewController func makeUIViewController(context: Context) -> UIViewController { factory() } func updateUIViewController(_ uiViewController: UIViewController, context: Context) {} ScrollView { ComposeContainer { Main_iosKt.ChatViewController() } .fixedSize(horizontal: false, vertical: true) } The ComposeUIViewController is created like this: fun buildComposeViewController( content: @Composable () -> Unit ): UIViewController = ComposeUIViewController { content() } When inspecting the

What does C89 standard say about the order of evaluation of expressions in a comma-separated sequence of declarators with initializers? I did not find the answer in the "Declarations" section, nor in "Initialization", nor in "Program execution". I just found that there are sequence points in the end of expressions in initializers (Annex C). For example: int t = 1; void block (void) { int a = (t *= 2), b = (t *= 3); /* Is it guaranteed that a==2 and b==6 ? */ }

I'm trying to make an animation of animal movements using the Seabird Tracking Animation Exercise (RPubs - gganimate tutorial) to help my own data. However when I go to plot the map my points do not show up. My basemap extent is set to the correct extent but the basemap that shows up is not correct. Any suggestions as to what might be going wrong? For context, I'm using my own data to make a visualization of an individual animal's movements that show movement to the same breeding area year over year. I expect the points from my df to show up on the map extent but nothing shows up. Map extent it gives me: xmin ymin xmax ymax -93.10445 30.96946 -93.00416 31.04072 map_bbox25 <- map_extent25 map_bbox26 <- map_extent26 map_bbox25 <- c (left=-93.2, bottom=30.9, right= -92.9, top=31.1) map_bbox26 <- c (left=-93.2, bottom=30.

I'm a beginner at Dart and I was doing a DSA problem to find the frequency of numbers in a list. And I have created a map with numbers as keys and frequencies of that number as its value. And then finally, I want to return the highest frequent number and its frequency as a Map. Here is my function code. MapEntry<int, int> findMostFrequent(List<int> numbers) { final frequency = <int, int>{}; //count logic here for (int i = 0; i < numbers.length; i++) { // frequency.update(numbers[i], (number) => number + 1, ifAbsent: () => 1); //here is the one lined version //here is the full logic if (!frequency.containsKey(numbers[i])) { frequency[numbers[i]] = 1; } else { frequency[numbers[i]] = frequency[numbers[i]]! + 1; } } return frequency.entries.reduce((a, b) { final aValue = a.value; final bValue = b.value; if (aValue == bValue) { return a.key > b

So, i have this assignment that requires me making dynamic arrays, the thing is that one of those arrays needs to be an array of structs, and the struct that it needs has strings, but also i cannot use new or delete meaning i need to use calloc, it looks kinda like this: #include <iostream> #include <string> using namespace std; struct person{ string name; string post; int age; char accessLvl; }; int main(){ int members = 2; person *guard = (person*)malloc( sizeof(person)* members); cout<<"How many guards are active: "<<endl; cin>>members; person *temp = (person*)realloc(guard, sizeof(person)*members); if(temp == NULL){ free(guard); return 1; } guard = temp; for(int i = 0; i < members; i++){ cout<<"\nname: "; getline(cin, guard[i].name); cout<<"post: "; getline(cin, guard[i].post);

Using the GNU linker, it is possible to embed the contents of a file into an object file (and eventually, an executable). For example, suppose my input is foo.bin and I want an object file named bar.o; I would write: ld --format binary --relocatable -o bar.o foo.bin (discussed in more detail in this question). Is it possible to do this with the LLVM linker? Or a related LLVM tool? If so, how? And if not - is that a real deficiency, or is it just that GNU ld is very "flexible" in what it's willing to do for you? Note: I'm mainly concerned with GNU/Linux systems, where the executable format is ELF.
