How to concatenate variables php/html? - php

Question

SO here is my code:
<?php
$image = '';
if (getUserChar($_SESSION['user_login']) == 1) {
$image = 'warrior';
echo '<div class="'.$image.'" stlye="top:'.$top_pos.'px;left:'.$left_pos.'px;"></div>';
}
elseif (getUserChar($_SESSION['user_login']) == 2) {
$image = 'mage';
echo '<div class="'.$image.'" stlye="top:'.$top_pos.'px;left:'.$left_pos.'px;"></div>';
}
elseif (getUserChar($_SESSION['user_login']) == 3) {
$image = 'archer';
echo '<div class="'.$image.'" stlye="top:'.$top_pos.'px;left:'.$left_pos.'px;"></div>';
}
?>
With that, the class seems to work fine. but with regard to the variables top_pos -- it doesnt.

Answer 1

I suspect your $top_pos and $left_pos variables are not being set or being overwritten somewhere.
<?php
function getUserChar($input) {
return $input;
}
// I suspect you have not set these anywhere or are being over written somewhere
$top_pos = 123;
$left_pos = 321;
$image = '';
$_SESSION['user_login'] = 1;
$input = getUserChar($_SESSION['user_login']);
if ($input == 1) {
$image = 'warrior';
} elseif ($input == 2) {
$image = 'mage';
} elseif ($input == 3) {
$image = 'archer';
}
echo '<div class="'.$image.'" style="top:'.$top_pos.'px;left:'.$left_pos.'px;"></div>';
