How to get an option selected?

Lauj

Below is a drop down list I have in my form.

<form name="frmScholarship" method="post" action="<?php $HTTP_SERVER_VARS['PHP_SELF']?>">
			<select name="sltScholarship" id="sltScholarship" onChange="frmScholarship.submit()">
			  <?php
do {  

?>
			  <option value="<?php echo $row_rsScholarshipType['sectionID']?>"<?php if (!(strcmp($row_rsScholarshipType['sectionID'], 100))) {echo "SELECTED";} ?>><?php echo $row_rsScholarshipType['category']?></option>
			  <?php
} while ($row_rsScholarshipType = mysql_fetch_assoc($rsScholarshipType));
  $rows = mysql_num_rows($rsScholarshipType);
  if($rows > 0) {
      mysql_data_seek($rsScholarshipType, 0);
	  $row_rsScholarshipType = mysql_fetch_assoc($rsScholarshipType);
  }
?>
			  </select>
			  </form>

The problem I have is that when a user select an option from the drop down list and the page refresh, the drop down option list that the user chose did not get selected after the page is refresh. How do I get the option selected to be selected and shown on the drop down list after the page refresh?

You have to check to see if it is set in the POST array, and if it is, then compare it to the currently returned row:

<option value="<?php echo $row_rsScholarshipType['sectionID']?>"
<?php 
if (!(strcmp($row_rsScholarshipType['sectionID'], 100))) {echo "SELECTED";}
if (isset($_POST['sltScholarship']) && $_POST['sltScholarship'] == $row_rsScholarshipType['sectionID']) {echo "SELECTED";} 
?>

<?php 
echo $row_rsScholarshipType['category']
?>
</option>

Many thanks for the help but it is still not working. Here's what I have so ar.

<?php
			$self = $HTTP_SERVER_VARS['PHP_SELF'];
			echo '<form name="frmScholarship" method="post" action="'.$self.'">';
			echo '<select name="sltScholarship" id="sltScholarship" onChange="frmScholarship.submit()">';
				//echo '<option value="None" selected>---Make Your Selection---</option>';
				while ($row_rsScholarshipType = mysql_fetch_assoc($rsScholarshipType)){
				$rows = mysql_num_rows($rsScholarshipType);
					if($rows > 0) {
						echo '<option value="'.$row_rsScholarshipType['sectionID'].'">';
						if (isset($HTTP_POST_VARS['sltScholarship']) && $HTTP_POST_VARS['sltScholarship'] == $row_rsScholarshipType['sectionID']) {echo "SELECTED";}
						echo $row_rsScholarshipType['category'];
						echo '</option>';
						}
					}			
			echo '</select></form>';
?>

No problem. I do recommend you use the superglobals $POST, $GET, $SERVER, etc, rather than $HTTP*_VARS option, because that can be disabled in PHP5, and is considered deprecated.

Many thanks for the help. The reason I didn't use the superglobal is because our php version is still 4.0 and so it's not going to work with just $_POST[' ']. However, I do have another question relating to this thread.

Now that it is working, is there a way to capture the selected option to a variable and display that option on the page? Below is the code I have:

			$self = $HTTP_SERVER_VARS['PHP_SELF'];
			echo '<form name="frmScholarship" method="post" action="'.$self.'">';
			echo '<select name="sltScholarship" id="sltScholarship" onChange="frmScholarship.submit()">';
				while ($row_rsScholarshipType = mysql_fetch_assoc($rsScholarshipType)){
					$rows = mysql_num_rows($rsScholarshipType);					
					if($rows > 0) {
						echo '<option value="'.$row_rsScholarshipType['sectionID'].'"';
						if (isset($HTTP_POST_VARS['sltScholarship']) && $HTTP_POST_VARS['sltScholarship'] == $row_rsScholarshipType['sectionID']) {echo "SELECTED";}
						echo '>';
						echo $row_rsScholarshipType['category'];
						echo '</option>';
						}
					}			
			echo '</select></form><p></p>';

The code above works just fine as you has helped me, but I also want to display the selected option on the page and bold it. Is there a way determine which option is selected and store that to a variable and display it later on the page?

Thank you,

Never mind, I think I got it.

Glad you got it. It probably seemed obvious when you read your question after typing it out. It's not as hard as it sounds at first. Feel free to post back for more help if needed, or mark the thread resolved if you're done with this one.
