How do i iterate over the $departments array and test to see if it equals the $name variable value and return "checked" if its in the list. departments is an array of checkboxes
function isChecked($name) {
$departments = (isset($_POST["interests"])) ? $_POST["interests"] : array();
foreach ($departments as $key => $value) {
// this next line here is wrong
if($departments[$key][$value] == $name) {
return "checked";
};
}
return "";
}
You're referring to the $value wrong inside the foreach loop. $value contains just what it says, the value of what is inside the $departments array.
function isChecked($name) {
$departments = (isset($_POST["interests"])) ? $_POST["interests"] : array();
foreach ($departments as $key => $value) {
if($value == $name) {
return "checked";
};
}
return "";
}
instead of if($departments[$key][$value] == $name)
use
if($value == $name)
You want to use either
if ($departments[$key] == $name) { ... }
or
if ($value == $name) { ... }
$department[$key] gives you the value at $key in the $department array, but that value is also helpfully stored in $value since you set it up in the loop definition.
Try this.
function isChecked($name) {
return isset($_POST['interests'][$name]);
}
If you need the function to return the string value checked if true, you can do this.
return isset($_POST['interests'][$name]) ? 'checked' : '';
