Display just selected value in listbox???

[zishan876]

Hi:
I have the following code which I inherited from a project I got assigned... I am trying to learn PHP along with this... So I have a listbox here that I just want to display the selected value and not the entire list... And this is read only so that the user can not change it or do anything to it...

   <select multiple size="10" name="preferred_locations[]">

  <?php
				$arrRegions = explode("\n", aParameter(802));
				
													
												
				//echo "<table width=100%>";

				foreach($arrRegions as $strRegion)
				{
				
					$arrCategoryItems = explode(".",$strRegion,2);
					
					if(strstr($arrCategoryItems[0],"."))
					{
						continue;
					}
					
					if($iCounter%2==0)
					{
						//echo "<tr height=24>\n";
					}
					 //echo "<td class=text>\n";
					 
					//echo "\n <option ".(in_array(trim($arrCategoryItems[1]), $arrSelectedLocations)?"selected":"")." value=\"".trim($arrCategoryItems[1])."\" name=\"preferred_locations[]\"> ".$arrCategoryItems[1]."</option>";
					  echo "\n <option ".(in_array(trim($arrCategoryItems[1]), $arrSelectedLocations)?"selected":"")." value=\"".trim($arrCategoryItems[1])."\" name=\"preferred_locations[]\"> ".$arrCategoryItems[1]."</option>";
					 
					//echo "\n <input disabled type=checkbox ".((is_array($arrSelectedLocations)&&in_array(trim($arrCategoryItems[1]), $arrSelectedLocations))?"checked":"")." value=\"".trim($arrCategoryItems[1])."\" name=\"preferred_locations[]\"> ".$arrCategoryItems[1];
					 //echo "</td>\n";
					
					if(($iCounter+1)%2==0)
					{
					 	//echo "</tr>\n";
					}
					$iCounter ++;
				}
				
				// echo "</table>";
				 
		?>
  
  </select>

Any help would be appreciated.. Thanks

After you submitted the form of which this <select> is part, the array preferred_locations[] will only contain the selected items.
Or am I missing the point of your question?

Well the list box has all the regions plus the selected ones highlighted... I was wondering if I can just display the hignlighted ones and not everything else... Maybe not a list box but just the answers the user chose...

As elck said once you submit the form, the array will contain only those options that where selected. So you can echo them out as you please.

Try this:

Once the form is submitted try looking in $_POST['preferred_locations'] for the selected options. Provided your form uses the POST method.
