User submits a form with many elements on it. I want to sort the user input alphabetically based on the field name before presenting it for review. I think I need to utilize an array for this, but don't know how. Thanks for any help.
Current code:
<?php
if (!$POST){
echo "<form action = '$PHP_SELF' method='POST'>
<input type = 'text' name = 'A Item'><br />
<input type = 'text' name = 'Z Item'><br />
<input type = 'text' name = 'L Item'><br />
<input type = 'text' name = 'B Item'><br />
<input type = 'text' name = 'Q Item'><br />
<input type = 'submit' value = 'submit' name = 'submit'></form>";
}
else {
foreach($POST as $key => $value) {
echo "$key $value <br />";
}
}
?>
Produces this result:
A_Item 3
Z_Item 8
L_Item 6
B_Item 7
Q_Item 9
submit submit
Desired result would be:
A_Item 3
B_Item 7
L_Item 6
Q_Item 9
Z_Item 8
