PHP - Utf-8 Encoding Not Working On Select Pages

Hi There,

Is there any way that I can get a select box to auto-select the value from a SQL query? For example, if I have a select box like this:

Dave,Jon,Simon,Fred

And a select statement that brings back the value of Fred then the select box (in HTML) would:

<select name='people'><option>Dave</option><option>Jon</option><option>Simon</option><option selected='selected'>Fred</option></select>

Same as if the name was Dave, or Simon etc etc.

Hope that makes sense?

Cheers
Matt

I'm experimenting out premade codes and trying to make them some how work the way I want to. This is "my" image uploader. For the uploader is suppose to find the image AND the code stored in mysql, but it doesn't seem to find it. any problem?
<?php 
$link = mysql_connect("localhost", "mcd", "whatanicepassword");
mysql_select_db("mcd", $link);


if (!isset($_POST["code"])) 
{
die ("Error: Not all fields complete");
}

$limit_size=5120;
$target = "skin/"; 
$target = $target . basename( $_FILES['uploaded']['name']); 
$ok=1; 
$filelol = $_FILES['uploaded']['name'];
$file_size=$_FILES['uploaded']['size'];
$filecheck = "skin/".$filelol;

//This is our size condition 

 if ($file_size >= $limit_size)
{ 
echo "Your file is too large.<br>"; 
$ok=0; 
} 
 
if (file_exists($filecheck))
{

} else {echo $filelol." does not exist in the database. Please upload at the main site.<br>";
$ok=0;}

// username and password sent from Form
$uploaded=mysql_real_escape_string($_POST['uploaded']); 
$code=mysql_real_escape_string($_POST['code']); 
$checkquery = mysql_query("SELECT * FROM user_list WHERE uploaded = '$uploaded' AND code = '$code'") or die("Error : " . mysql_error());

$num_rows=mysql_num_rows($checkquery);
if ($num_rows < 1 ) { 
          echo 'File not found in MySQL<br><br><br>';
          $ok=0;
}    
else 
{echo 'YES!';}


//This is our limit file type condition 
if (($_FILES["uploaded"]["type"] != "image/png"))
{
echo "You may only upload PNG files.<br>";
$ok=0;
} 

if ($ok==0) 
 { 
 Echo "Sorry your file was not uploaded<br>"; 
 } 
 //If everything is ok we try to upload it 
 else 
 { 
 if(move_uploaded_file($_FILES['uploaded']['tmp_name'], $target)) 
 { 
 echo "The file ".$filelol." has been uploaded"; 
 } 
 else 
 { 
 echo "Sorry, there was a problem uploading your file."; 
 } 
 } 
 ?>

Not really sure what to ask because I don't know what the problem is. Maybe just need a fresh set of eyes to find out whats wrong.
I am trying selecting content from a database table but its not working.  I am not getting any errors just a blank screen where the content should be displayed.

html
Code: [Select]
<table>
<tbody>
<tr>
<th>Topic</th>
<th>Name</th>
<th>Date</th>
  </tr>
  <?php include 'server/forum.php'; ?>
</tbody>
</table>

php
Code: [Select]
<?php

require_once('load_data.php');

$con = mysql_connect($db_host, $db_user, $db_pwd);

if (!$con)
{
die('Could not connect to database: ' . mysql_error());
}

$dbcon = mysql_select_db($database);

if (!$dbcon)
{
  die('Could not select database: ' . mysql_error());
}

$sql = "SELECT * FROM $table ORDER BY id";
$result = mysql_query($sql) or die("Error ". mysql_error(). " with query ". $sql);

if (!$result) 
{
die("Query to show fields from table failed:".mysql_error());
}

$row = mysql_fetch_array($result)

while($row)
{
echo '<tr>';    
echo '<td class="forumtd"><b>';
echo '<a href="topic.php?id='.$row['id'].'">'.stripslashes(htmlspecialchars($row['topic'])).'</a>';
echo "</b></td>";
echo '<td class="forumtd"><em>';
echo stripslashes(htmlspecialchars($row['name']));
echo "</em></td>";
echo '<td class="forumtd">';
echo date("l M dS, Y", $row['date']);
echo "</td>";
echo "</tr>";
}

mysql_close($con);

?>

Hi there,

I'm having a problem with updating a record with an UPDATE mysql query and then following that query with a SELECT query to get those values just updated.

This is what I'm trying to do...I'd like a member to be able to complete a recommended task and upon doing so, go to a page in their back office where they can check off that task as "Completed".  This completed task would be recorded in their member record in our database so that when they return to this list, it will remain as "Completed".  I'm providing the member with a submit button that will call the same page and then update depending on which task is clicked as complete.

Here is my code:
Code: [Select]
$memberid = $_SESSION['member'];

// Check if form has been submitted
if(isset($_POST['task_done']) && $_POST['task_submit'] == 'submitted')
{
  $taskvalue = $_POST['task_value'];
  $query = "UPDATE membertable SET $taskvalue = 'done' WHERE id = $memberid";
  $result = mysqli_query($dbc, $query);
}

$query ="SELECT task1, task2, task3 FROM membertable WHERE id = $memberid";
$result = mysqli_query($dbc, $query);
$row = mysqli_fetch_array($result, MYSQLI_ASSOC);

$_SESSION['task1'] = $row['task1'];
$_SESSION['task2'] = $row['task2'];
$_SESSION['task3'] = $row['task3'];
?>
<h4>Task List</h4>
<table>

  <form action="" method="post">
    <tr>
      <td>Task 1</td>
      <td><?php if($_SESSION['task1'] == 'done') {echo '<div>Completed</div>';} else{ echo '<input type="submit" name="task_done" value="Mark As Completed" />';} ?></td>
    </tr>
    <input type="hidden" name="task_value" value="task1" />
    <input type="hidden" name="task_submit" value="submitted" />
  </form>

  <form action="" method="post">
    <tr>
      <td>Task 1</td>
      <td><?php if($_SESSION['task1'] == 'done') {echo '<div>Completed</div>';} else{ echo '<input type="submit" name="task_done" value="Mark As Completed" />';} ?></td>
    </tr>
    <input type="hidden" name="task_value" value="task2" />
    <input type="hidden" name="task_submit" value="submitted" />
  </form>

  <form action="" method="post">
    <tr>
      <td>Task 1</td>
      <td><?php if($_SESSION['task1'] == 'done') {echo '<div>Completed</div>';} else{ echo '<input type="submit" name="task_done" value="Mark As Completed" />';} ?></td>
    </tr>
    <input type="hidden" name="task_value" value="task3" />
    <input type="hidden" name="task_submit" value="submitted" />
  </form>

</table>

The problem that I am having is that the database is not updated with the value "done" but after submission, the screen displays "Completed" instead of "Mark As Completed".  So the value is being picked up as "done", but that is why I have the SELECT after the UPDATES, so that there is always a current value for whether a task is done or not.  Then I refresh and the screen returns the button to Mark As Complete.  Also, when I try marking all three tasks as, sometimes all three are updated, sometimes only one or two and again, I leave the page or refresh and the "Marked As Completed" buttons come back.  Bizarre.  If anyone can tell me where my logic is going wrong, I would appreciate it.

I had this working, but when I try and get fancy and use AJAX the data doesn't display. I think this is a PHP problem though.

My code for the select form including AJAX code

Code: [Select]

echo ("<td>");

mysql_close($conn);

I think the problem is either with this part in the AJAX
Code: [Select]
xmlhttp.open("GET","Query.php?category_id="+str,true);

or most likely in my Query.php code

when I wasn't using AJAX and using POST it worked fine, but adding the AJAX stuff and GET it doesn't work.

When I echo out the SQL the result is

Code: [Select]
SELECT * FROM sports INNER JOIN players ON sports.category_id = players.category_id WHERE players.category_id = ''

so the category_id is not being selected properly and that is the primary key/foreign key in the MySQL table which connects the JOIN.
