Can't seem to get the second array element to print out...please help!
There are two campers, each with a complete set of information, in the array
$displayCampersOfParent

The current display only shows the first camper's information, and then the for loop terminates...
<?php
		// insert short blocks for parent, all campers
		/*echo '<pre>';
		print_r($displayCampersOfParent);
		echo '</pre>';*/
		
		// display camper name, selection of sessions
		for ($i = 0; $i < count($displayCampersOfParent); $i++){
			
			// set camper number loop
			$loop_counter = 1;
			echo $loop_counter;
			
			echo '<dl><h3>';
			echo $displayCampersOfParent[$i]['t_firstname_en'] .' ';
			echo $displayCampersOfParent[$i]['t_lastname_en'];
			echo '</h3>';
			if ($_SESSION['UserLang'] == 'JP'){
				echo '<br />';
				echo $displayCampersOfParent[$i]['t_lastname_jp'] .' ';
				echo $displayCampersOfParent[$i]['t_firstname_jp'];
			}
			echo '<br />';
			
			// display 3 session selection blocks
			for ($session_loop_counter = 1; $session_loop_counter < 4; $session_loop_counter++){
				
				echo '<dt><span class="NoStarRequired">* </span>';
				echo $CampSessionSelection;
				echo '</dt><dd>';
				echo '<select name="';
					echo 'Camper_' .$loop_counter .'_Session_' 
						.$session_loop_counter .'_List'; 
					echo '" ';
					echo 'id="';
					echo 'Camper_' .$loop_counter .'_Session_' 
						.$session_loop_counter .'_List'; 
					echo '">';
					echo '<option value="">';
					echo $CamperSessionOptions; 
					echo '</option>';
					for ($i = 0; $i < count($obj->mRegSessions); $i++){
					  
						  // build session dates
						  $date_start = date_create($obj->mRegSessions[$i]['d_startdate']);
						  $date_end = date_create($obj->mRegSessions[$i]['d_enddate']);
						  $print_date_start = date_format($date_start, 'n/d/Y');
						  if ($date_start == $date_end){
							  $print_date_end = '';
						  } else {
							  $print_date_end = date_format($date_end, 'n/d/Y');
						  }
						  
						  // output session dates
						  if ($_SESSION['UserLang'] == 'EN'){
							  $ProgramName = $obj->mRegSessions[$i]['t_program_name_en'];
							  $SessionName = $obj->mRegSessions[$i]['t_session_name_en'];
						  } else {
							  $ProgramName = $obj->mRegSessions[$i]['t_program_name_jp'];
							  $SessionName = $obj->mRegSessions[$i]['t_session_name_jp'];
						  }
							  
						  if ($SessionName == '') {
							  echo '<option value="' .$obj->mRegSessions[$i]['pk_session'] .'">'
							  .$ProgramName ."&nbsp;&nbsp;" .$print_date_start 
							  ." &mdash; " .$print_date_end .'</option>';
						  } else {
							  echo '<option value="' .$obj->mRegSessions[$i]['pk_session'] .'">'
							  .$ProgramName .', ' .$SessionName .": " .$print_date_start 
							  ." &mdash; " .$print_date_end .'</option>';
						  }
      				 } // end for loop
    			echo '</select></dd>';
			
			// end session display for loop--3 repetitions
			}
			
			
			// end this camper's session registration block
			echo '</dl>';
			
			// increment counter
			$loop_counter++;
			echo $loop_counter;
		// end for loop, after displaying all campers	
		}
     ?>

You reused $i as a loop counter in line 42. You initially declared it in line 8. You are most likely overwriting the value in the 2nd loop, so by the time the first loop comes around a 2nd time, you have already exceeded the bounding condition. Try using different variables for each loop.

I can't see the error. What do you get when you

echo count($displayCampersOfParent);

Open in new window


Can you show the output from
   	        /*echo '<pre>';
		print_r($displayCampersOfParent);
		echo '</pre>';*/

Kaufmed,
Fantastic. I stared at this thing for 30 minutes, and never saw the two $i variables. I put in $j and it worked immediately.
Thanks!
