Interpret image coordinates submitted for animated image elements in a form
I want to capture the X:Y values indicating where the user clicked on the animated image by checking the php $_POST array. The problem is that while I can get the input submission information on the static image, I can't seem to get any values from the animated image.
Here are the complete HTML pages and forms that demonstrate this behavior:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Gunfighter Testing Page</title>
<style>
div {
width:24px;
height:24px;
position:relative;
-webkit-animation:glide 1s ease-in-out alternate infinite;
}
@-webkit-keyframes glide {
from {
left:-400px;
top:0px;
}
to {
left:400px;
top:0px;
}
}
</style>
</head>
<body>
<center>
<form method="post">
<input type="image" name="Staredown" value="Staredown" alt="Staredown" src="https://i.imgur.com/sQwX4Qg.png">
<input type="image" name="Gesture" value="Gesture" alt="Gesture" src="https://i.imgur.com/0iJnH5Q.png"><br>
<div><input type="image" name="Shoot" value="Shoot" alt="Shoot" src="https://i.imgur.com/i9oV2j3.png"></div> ;
</form>
</center>
</body>
Here is some php that checks form (button) submission and displays the coordinates within the clicked image:
<?php
//var_dump($_POST);
echo "Form (button click) results (a pefect score is x=32 and y=32: <br>\n";
echo "<p>\n";
if ((isset($_POST["Staredown_x"])) || (isset($_POST["Gesture_x"])) || (isset($_POST["Shoot_x_x"]))){
switch(true){
case (isset($_POST["Staredown_x"])):
echo "Staredown click coords=>
break;
case (isset($_POST["Gesture_x"])):
echo "Gesture click coords=>
break;
case (isset($_POST["Shoot_x"])):
echo "Shoot click coords=>
break;
}
} else {
echo "Score will be displayed upon clicking on a button.<br>\n";
}
?>
Why can I get the click coordinates in the clicked image (if they are static), but can't get the animated image to behave the same way? The animated image does not populate $_POST["Shoot_x"] with the coordinates of the click (or register in any other way that I can seem to collect in php).
