Thank you sir. I originally had a if (isset($_POST['submit'])){ which was great for the button but those errors stopped the rebuild of my project in it's tracks....

Hello, I am getting an undefined array key message for my wp_widget_factory method in my functions.php file. I am not sure how to make an isset if loop for that.

[@TheWheelchairGuy]

I cannot give you a specific answer because I cannot see your code

[@ritabratagoswami7724]

I'm passing my id (auto_incre) through JavaScript like this:-
function showFunc(id)
{
let formData = new FormData();
formData.append("file_id_show", id);
var xmlObj = new XMLHttpRequest();
xmlObj.open("POST", "get_image.php");
xmlObj.send(formData);
// alert("The Show id is:- " + id);
}
i tested alert box it properly working showing respective id . But when it is going to other php page like this:-
$display_id = $_POST['file_id_show'];
it showing Undefined array key "file_id_show".
Any solution?
Remember all the thing is happening through JS.

[@TheWheelchairGuy]

Make sure you wrap all of your php code in the if statement with the isset

Hi. I am having an issue, stil learning php. I have two checkboxes right, i used foreach to echo the variables. but if i do not pick one how do i display a message without triggering that undefined key error? Thanks

[@TheWheelchairGuy]

you can basically use an if else condition to print different messages on different conditions

[@hotwings9382]

@@TheWheelchairGuy alright thanks. I managed to do an if isset on the submit button then I did another if !empty($_POST['var'] then foreach and it worked

[@zoevdboogaert2303]

whenever I do this I keep getting "Parse error: syntax error, unexpected token ";" in C:\xampp\htdocs\MyWebsite\form.php on line 3" what can I do now?? Pls help

[@TheWheelchairGuy]

[@serogapeterson8648]

So wtf is this then? Why this shit happens?

[@rifahjoita5409]

Sound is very low.

[@TheWheelchairGuy]

I think it’s the opposite because people tell me it’s loud

[@shiaze]

why does this happen?? it doesn't make senseeee

[@TheWheelchairGuy]

It makes sure that it is not set to null
