[RESOLVED] Mentor's Name NOT displaying

[Php_Beginner2]

Hi there, I am doing the mentoring system I am having problem when I try to register a mentee into the system. The name of the "Mentor" I have chose from the 'register page' which in the drop down list form cannot be displayed. Once I click the register button, all the contents I have entered in the 'Register Page' appear in the 'Register Confirmation Page' except the mentor's name.

Here the codes for the mentor's name drop down list in the "Register Page":

<select style="color: #009; font-family: Verdana, Geneva, sans-serif; font-size: 11px;" name="lect_id2" id="lect_id2">
  <?php do {?>
  <option value="<?php echo $row_addlectstu['lect_id']?>"<?php if (!(strcmp($row_addlectstu['lect_id'], $_REQUEST['lect_id']))) {echo "selected=\"selected\"";} ?>><?php echo($row_addlectstu['lect_name'])?></option>
  <?php
} while ($row_addlectstu = mysql_fetch_assoc($addlectstu));
$rows = mysql_num_rows($addlectstu);
if($rows > 0) {
mysql_data_seek($addlectstu, 0);
$row_addlectstu = mysql_fetch_assoc($addlectstu);
}
?>
</select>

Code that display the mentor's name in "Register Confirmation page":

<?php echo $lecturer_id=$_REQUEST['lect_id'];
$zzz = mysql_query("SELECT * FROM lecturer WHERE lect_id='$lecturer_id'");
if($zzz = mysql_fetch_assoc($zzz)){
echo $xxx=$zzz['lect_name'];}
?>

The codes do not prompt me any notices of index error or warning when i try to run my registering pages locally, the only problem is the mentor's name not showing up in the "Register Confirmation Page". 😕

echo $lecturer_id=$_REQUEST['lect_id'];

that's not right, the echo should not be there

echo $xxx=$zzz['lect_name'];

this one as well, you can't echo and assign on the same line.

Actually, you can, and it's because the assignment operator evaluates to the right-hand side of the binary operation. In other words, this:

echo $foo = "Hello World!\n";
var_dump($foo);

will output this:

Hello World!
string(13) "Hello World!
"

If you're still not convinced, just think about how this all-too-familiar construct works:

while($row = mysql_fetch_assoc($query)) {

The return value of the function is assigned to $row, and that value is then evaluated in the while() conditional.

Correct of course,

I just got back from a week off on Great Barrier Island, my brain is still on vacation :-)
