position the result base on row number in mysql - php

Question

I have this function (refer below)
function showMenu(){
$result = mysqli_query($con,"SELECT * FROM user_menu");
$menu = '<nav id="main-menu"><ul class="menuwrapper extend">';
while($row = mysqli_fetch_array($result))
{
$menu .= '<li class="' . $row['status'] . '">' . $row['name'] . '</li>';
}
$menu .= '</ul></nav>';
return $menu;
}
and my database table is structured as follows (refer below)
id(BigInt 100, AUTO_INCREMENT, PRIMARY)
name(text, utf8_general_ci)
url(varchar 100, utf8_general_ci)
status(text, utf8_general_ci)
key(int 30)
The contents of that table are (refer
below)
id = "1", name = "Post", url = "http://localhost/gadgetmarket/admin/index.php", status="default", key = "0"
id = "2", name = "Pages", url = "http://localhost/gadgetmarket/admin/pages.php", status="parent", key = "1"
id = "3", name = "Menus", url = "http://localhost/gadgetmarket/admin/menus.php", status="parent", key = "2"
id = "4", name = "Theme", url = "http://localhost/gadgetmarket/admin/theme.php", status="parent", key = "3"
Now, my question is how could I output the result base on there keys number that each menu has on? my expected output base on what im trying to achieve from the datas above is (refer below)
<nav id="main-menu">
<ul class="menuwrapper extend">
<li class="default">
Post
</li>
<li class="parent">
Pages
</li>
<li class="parent">
Menus
</li>
<li class="parent">
Theme
</li>
</ul>
</nav>
As you can see the output was arrange base on keys order. Any recommendations, suggestions and ideas will be greatly appreciated. Thanks in advance.

Answer 1

For a start, you're not declaring the connection global in your function
function showMenu(){
global $con; // SIMPLY ADD THIS LINE
$result = mysqli_query($con,"SELECT * FROM user_menu");
$menu = '<nav id="main-menu"><ul class="menuwrapper extend">';
while($row = mysqli_fetch_array($result))
{
$menu .= '<li class="' . $row['status'] . '">' . $row['name'] . '</li>';
}
$menu .= '</ul></nav>';
return $menu;
}
and you can use ORDER BY to fetch the data the way you want it
SELECT * FROM user_menu ORDER BY key ASC
