I'm working on my task right now, which accessing specific array when it is called by front end. My example data is like this
{
"data": [
{
"name": "Jon Snow",
"id": "01-0001",
},
{
"name": "Robert Stark",
"id": "01-0002"
},
{
"name": "Sansa Stark",
"id": "01-002333"
},
{
"name": "Arya Stark",
"id": "01-00012"
},
{
"name": "Bran Stark",
"id": "01-0003"
},
{
"name": "Rickon Stark",
"id": "01-0005"
}
]
}
* In my front end I have this code *
selectedEmployee: any=null;
setActiveEmployee(employee: any) {
this.selectedEmployee = employee;
let myJSON = JSON.stringify(this.selectedEmployee);
this.perEmpLateEarly();
}
Whenever I choose the employee i get the id of that employee. So in this, if i choose "id": "01-0001" it will return the first array and it will keep the rest, and if I choose "id": "01-0002" it will return the second one and will keep the rest and so on. How can I do that in Php?
Thanks in advance
You will do a GET/POST HTTP request from frontend, which would look something like this in
your_backend_page.php?id=<ID HERE>
Then the "your_backend_page.php" would look like as follows:
$list = { "data": [ { .... }, { ... }] } // this is the array you have
$idFromFrontEnd = $_GET["id"];
foreach ($list["data"] as $item) { // iterate over all items
if ($item["id"] == $idFromFrontEnd) { // check if id matches
echo json_decode($item); // if matches, print this item
}
}
Please note this approach is okay if you have a small number of items. For a larger list, you might want to have a database, where you can use sql to select.
