PHP Update shows previous database entry's - php

Question

I'm currently just coding around in my free time and follow up some random tutorials that other developers/coder's created in there spare time. Now I'm stuck with something very small. I have been trying to find a answer on the interwebz but I cant seem to find one, so here I'm hoping that someone is willing to read my PHP and HTML and see the error I created.
But before I share my code let me tell you what my problem is and what I try to achieve.
If you go to the following link "removed because problem is solved." and when you click on Home/About/Service/Random, you are able to edit one of these menu's. (title, posistion, visible). Now when I want to change the menu name "Home" to "Welcome" it correctly execute my SQL but for some reason, in the HTML Form it loads it's previous information. What I can do is copy the PHP and save it in a new php file and when clicking on submit it will change both menu/title/html form at the same time, but it wont show my succes and fail message anymore. I hope any of you understand what I'm trying to explain here and try to achieve. Now lets share the code.
PHP
<? find_selected_page(); ?>
<?
if (intval($_GET['info']) == 0){
redirect_to("content.php");
}
if(isset($_POST['submit'])){
$errors = array();
$required_fields = array('menu', 'position', 'visible');
foreach ($required_fields as $fieldname){
if (!isset($POST[$fieldname]) || (empty($_POST[$fieldname]) &&
!is_numeric($_POST[$fieldname]))) {
$errors [] = $fieldname;
}
}
$fields_with_lengths = array('menu' => 30);
foreach($fields_with_lengths as $fieldname => $maxlength) {
if(strlen(trim(mysql_prep($_POST[$fieldname]))) > $maxlength){
$errors[] = $fieldname;
}
}
$id = mysql_prep($_GET['info']);
$menu = mysql_prep($_POST['menu']); //use post array cuz we used post var to coll val in form
$position = mysql_prep($_POST['position']);
$visible = mysql_prep($_POST['visible']);
$query = "UPDATE information SET menu = '{$menu}', position = {$position}, visible = {$visible} WHERE id = {$id}";
$result = mysql_query($query, $connection);
if (mysql_affected_rows() == 1) {
$message = "The information was correctly updated.";
} else {
//failed
}
} else { //errors
}
?>
HTML
<? require_once ("includes/functions.php"); ?>
<? require_once ("includes/connect.php"); ?> //HERE IS MY CONNECTION TO MY DATABASE
///HERE IS MY PHP CODE
<? include ("includes/header.php"); ?>
<div id="content"> <!-- content here -->
<table id="table">
<tr>
<td id="nav">
<? echo navigation($sel_table1, $table2); ?>
</td>
<td id="main">
<h2>Edit Info <? echo $sel_table1['menu']; ?></h2>
<? if (!empty($message)) { echo "<p class=\"message\">" . $message . "</p>";} ?>
<form action="edit_info.php?info=<? echo urlencode($sel_table1['id']); ?>" method="post"/>
<p>Menu title
<input type="text" name="menu" value="<? echo ($sel_table1['menu']); ?>" id="menu">
</p>
<p>Position
<select name="position">
<?
$info_set = get_all_info();
$info_count = mysql_num_rows($info_set); //asks how many rows there are should be 3
for($count=1; $count <= $info_count+1; $count++){
echo "<option value='{$count}'";
if($sel_table1['position'] == $count){
echo "selected";
}
echo ">{$count}</option>";
}
?>
</select>
</p>
<p>Visible:
<input type="radio" name="visible" value="0"
<? if ($sel_table1['visible'] == 0){ echo "checked"; } ?>
/>No
<input type="radio" name="visible" value="1"
<? if ($sel_table1['visible'] == 1){ echo "checked"; } ?>
/>Yes
</p>
<input type="submit" name='submit' value="Edit information" />
</form> <br>
Cancel
</td>
</tr>
</table>
</div>
<? include ("includes/footer.php");?> //HERE I HAVE IF ISSET MYSQL CLOSE
And a more simple short version of the story is, I want to update the menu's with the success and failure message's without getting the old previous data in my HTML FORM
if needed for any reasons I have included the part of my functions.php where $sel_table and $table2 are staying.
function find_selected_page(){
global $sel_table1;
global $table2;
if (isset($_GET['info'])){
$sel_table1 = get_info_by_id($_GET['info']);
$sel_t2 = 0;
$table2 = NULL;
} else if (isset($_GET['page'])){
$table1 = 0;
$sel_table1 = NULL;
$table2 = get_pages_by_id($_GET['page']);
} else {
$table1 = NULL;
$sel_table1 = NULL;
$table2 = 0;
}
}
function navigation($sel_table1, $table2){
$output = "<ul class='info'>";
$info_set = get_all_info();
while ($info = mysql_fetch_array($info_set))
{
$output .= "<li"; if ($info["id"] == $sel_table1 ["id"]){
$output .= " class='selected'";
}
$output .= "><a href='edit_info.php?info=" . urlencode($info["id"]) . "'>{$info['menu']}</a></li>";
$page_set = get_pages_for_info($info["id"]);
$output .= "<ul class='pages'>";
while ($page = mysql_fetch_array($page_set))
{
$output .= "<li"; if ($page["id"] == $table2 ["id"]){
$output .= " class='selected'";
}
$output .= "><a href='content.php?page=" . urlencode($page["id"]) . "'>{$page['menu']}</a></li>"; }
$output .= "</ul>";
}
$output .= "</ul>";
return $output;
}
