Can anyone tell why my $display_block variable is not showing up properly when I choose the test1 choice from the select list and press submit? It displays correctly (which is above the footer) when I choose the test2 choice from the select list or when the page is initially loaded. What have I done wrong? Can anyone see? Here is my page:

 

<?php

session_start();

include("connect_db.php");

if ((isset($_GET['train'])) && ($_GET['train'] == 'test1')) {

$display_block = "<h3>Train Your Character To Level Up</h3>
<h4>Choose a different <a href=choose_train.php>character</a> to train?</h4>
<table cellpadding=3 cellspacing=3>
<tr>";

$get_player_info = "select * from training WHERE identity = '$_GET[identity]'";
$get_player_info_res = mysql_query($get_player_info, $conn) or die(mysql_error());

while ($player_info = mysql_fetch_array($get_player_info_res)) {

    $id = $player_info['id'];
    $identity = $player_info['identity'];
    $level = $player_info['level'];
    $energy = $player_info['energy'];
    $experience = $player_info['experience'];
    $update_energy = ($energy - 2);
    $update_experience = ($experience + 50);
    
    if ($energy > 0) {

$lose_energy = mysql_query("UPDATE training SET energy ='$update_energy' WHERE identity = '$identity'");
$gain_experience = mysql_query("UPDATE training SET experience ='$update_experience' WHERE identity = '$identity'");

}

$display_block .= "
<td valign=top>
<form action=train.php>
<select name=train>
<option>test1</option>
<option>test2</option>
</select>
<input type=submit name=submit value=Train>
<input type='hidden' name='identity' value='$identity' />
</form>
</td>
<td valign=top>Player: $identity<br />
Level: $level<br />
Energy: $energy<br>
Current Experience: $experience<br />

</td>
</tr>";

}//end while
}//end if

elseif ((isset($_GET['train'])) && ($_GET['train'] == 'test2')) {

$display_block = "<h3>Train Your Character To Level Up</h3>
<h4>Choose a different <a href=choose_train.php>character</a> to train?</h4>
<table cellpadding=3 cellspacing=3>
<tr>";

$get_player_info = "select * from training WHERE identity = '$_GET[identity]'";
$get_player_info_res = mysql_query($get_player_info, $conn) or die(mysql_error());

while ($player_info = mysql_fetch_array($get_player_info_res)) {

    $id = $player_info['id'];
    $identity = $player_info['identity'];
    $level = $player_info['level'];
    $energy = $player_info['energy'];
    $experience = $player_info['experience'];
    $update_energy = ($energy - 10);
    $update_experience = ($experience + 100);
    
    if ($energy > 0) {

$lose_energy = mysql_query("UPDATE training SET energy ='$update_energy' WHERE identity = '$identity'");
$gain_experience = mysql_query("UPDATE training SET experience ='$update_experience' WHERE identity = '$identity'");

}

$display_block .= "
<td valign=top>
<form action=train.php>
<select name=train>
<option>test1</option>
<option>test2</option>
</select>
<input type=submit name=submit value=Train>

</td>
<td valign=top>Player: $identity<br />

}

if ($energy <= 0) {
$display_block .= "You cannot train once your energy is depleted. Please rest.";
}

$display_block .= "</table>";

} else {

$display_block .= "Your character did not train.";

This is train.php:

<table cellpadding=3 cellspacing=3>
<tr>";

$get_player_info = "select * from training WHERE identity = '$_GET[identity]'";
$get_player_info_res = mysql_query($get_player_info, $conn) or die(mysql_error());

while ($player_info = mysql_fetch_array($get_player_info_res)) {

    $id = $player_info['id'];
    $identity = $player_info['identity'];
    $level = $player_info['level'];
    $energy = $player_info['energy'];
    $experience = $player_info['experience'];
    $update_energy = ($energy - 2);
    $update_experience = ($experience + 50);
    
    if ($energy > 0) {

$lose_energy = mysql_query("UPDATE training SET energy ='$update_energy' WHERE identity = '$identity'");
$gain_experience = mysql_query("UPDATE training SET experience ='$update_experience' WHERE identity = '$identity'");

Here is what's supposed to look like:

I can't see any issues (the if and elseif clauses appear to be identical - I assume that's just for testing?)

 

I'd try playing with the structure a bit. A quick swap of test1 and test2

might give you a clue (add something unique to one of the clauses for test purposes):

 

if ((isset($_GET['train'])) && ($_GET['train'] == 'test2')) {

....

}

elseif ((isset($_GET['train'])) && ($_GET['train'] == 'test1')) {

.....

?

 

you could also try a differnt structure like a switch:

if (isset($_GET['train']){

  switch ($GET_['train']){

    case 'test1:

    case 'test2:

    default:

}

else{

  fail

}

or nested if statements

 

if (isset($_GET['train']){

  if ($_GET['train'] == 'test1'){

  }

  else{ //test2

  }

}

else{

  fail

}

 

I'm not saying there's anything wrong with your structure, but it might be easier to trace one condition at a time with a more obvious structure.
