fetch() not returning first row - php

Question

I am trying to update code that has been written using prepared statements. This is my first time using them and I am having difficulty retrieving all the results. When I use a direct SQL statement, it works so I don't think that's the problem.
The code will not return any results until there are at least two that match the query, then it will return all but the first row. I tried using fetchAll, but that gives different error about a call to an undefined method.
Thanks in advance for any help that you can provide. If it's not to much to ask, please provide example or reference I can refer to and complete my understanding.
function html_competitive_make_gallery ($init) {
global $USER;
$user_id = $USER->id;
$page_name = 'competitive';
$base_name = $init['base_name'];
global $link;
$sql_pre = "SELECT form_id, community_id FROM frm_root WHERE user_id = ?
AND page_name = ? ORDER BY last_modified_date DESC LIMIT 1";
$stmt = $link->prepare($sql_pre);
$stmt->bind_param('is', $user_id, $page_name);
$stmt->execute();
$stmt->bind_result($form_id,$community_id);
$stmt->fetch();
$stmt->close();
$sql = "SELECT data FROM tester WHERE type= '".$base_name."'
AND form_id= '".$form_id ."' AND community_id= '". $community_id ."' LIMIT 5";
$stmt = $link->prepare($sql);
$stmt->execute();
$stmt->bind_result($data);
$stmt->fetch();
$html[]='<div class="gallery" style ="width:100%;height:30%;overflow:hidden;">';
while ($stmt->fetch()){
echo $data;
}
$stmt->close();
$html[]='</div>';
return implode ( $html);
}

Answer 1

You're running fetch() before entering your loop, hence dropping the first row of your results:
$stmt->execute();
$stmt->bind_result($data);
$stmt->fetch(); // <<< THIS LINE SHOULD NOT BE HERE
$html[]='<div class="gallery" style ="width:100%;height:30%;overflow:hidden;">';
while ($stmt->fetch()){
echo $data;
}
$stmt->close();

Answer 2

Try this:
while ($data = $stmt->fetch()){
echo $data;
}
$stmt->close();

Answer 3

Your main problem is called "mysqli".
You will face such problems as long as you're using mysqli with prepared statements.
Just quit it and use PDO:
function html_competitive_make_gallery ($init) {
global $USER;
global $link;
$sql_pre = "SELECT form_id, community_id FROM frm_root WHERE user_id = ?
AND page_name = ? ORDER BY last_modified_date DESC LIMIT 1";
$stmt = $link->prepare($sql_pre);
$stmt->execute(array($USER->id, 'competitive'));
return $stmt->fetch();
}
