two forms, second populated from the first one, after submision it resets

Dzordz

I have two form and in connection with the selection of the first one the second is populated.
The problem is after I submit the second one the reset and I want to keep the state of the second form intacked (as it was).

So I select one league and than I want to be able to browse through the teams of that league without having to select the league over and over again 🙂

Hope I was clear enough 🙂

help anyone? 🙂

Chose a league!
<form method="post" action="indexo.php">
<select name="league">
<?php

//creates the drowpdown menu for selection of the league

$count_teams = file ("leagues.dat");
$size_leagues = count ($count_teams);
for ($counter = 0; $counter < $size_leagues; $counter++)
   {
   echo "<option>$count_teams[$counter]</option>";
   }
?>
</select>
<input type="submit" value="Select">
</form>
<?php
$chosen_league = $_POST['league'];
echo $chosen_league;
?>
<hr>

<form method="post" action="indexo.php">
<?php
echo "<select name='league_again'>";
echo "<option>$chosen_league</option>";
echo "</select>";
?>
<select name="team">
<?php
$selected_league = file ($_POST['league'] . ".dat");
$count_league = count ($selected_league);

for ($counter = 0; $counter < $count_league; $counter++)
   {
   echo "<option>$selected_league[$counter]</option>";
   }
?>
</select>
<input type="submit" value="Submit">
</form>

Hi Dzordz,

There are lots of different ways to achieve the sort of thing you are looking to do.

It's probably easier to just show you a way than try to explain. The following could be adapted, of course, ...

<?php
// Find out whether a league has been selected
$SELECTED_LEAGUE = isset($_REQUEST['league'])? $_REQUEST['league']: -1;
$SELECTED_TEAM = isset($_REQUEST['team'])? $_REQUEST['team']: -1;
?>
<html>
<head>
<title></title>
</head>
<body>
 <!-- No need to use post ... can complicate the user's experience -->
<form method="get" action="<?php echo $_SERVER['PHP_SELF']; ?>">
	<select name="league"> 
<?php 
//creates the drowpdown menu for selection of the league 
$leagues = file('leagues.dat');
$count_leagues = count($leagues); 
for($i = 0; $i < $count_leagues; $i++){ 

// Must trim each entry of carriage returns and other whitespace
$leagues[$i] = trim($leagues[$i]);

// Decide whether this option is selected 
$selected = ($i == $SELECTED_LEAGUE)? ' selected': '';

echo '<option value="'.$i.'"'.$selected.'>'.$leagues[$i].'</option>';
}
?>
	</select>
	<input type="submit" value="Select">
</form> 
<?php 

// Now, only show the second form if a selection 
// has been made on the first form
if($SELECTED_LEAGUE == -1){
?>
<p>Choose a league!</p>
<?php
} else {
	$league_title = $leagues[$SELECTED_LEAGUE];
?> 
<hr>
<h1><?php echo $league_title; ?></h1>
<form method="get" action="<?php echo $_SERVER['PHP_SELF']; ?>"> 
	<input type="hidden" name="league" value="<?php echo $SELECTED_LEAGUE; ?>">
	<select name="team"> 
<?php 

$teams = file(strtolower($league_title).'.dat'); 

$count_teams = count($teams); 
for ($i = 0; $i < $count_teams; $i++){

	// Must trim each entry of carriage returns and other whitespace
	$teams[$i] = trim($teams[$i]);

	// Decide whether this option is selected 
	$selected = ($i == $SELECTED_TEAM)? ' selected': '';

	echo '<option value="'.$i.'"'.$selected.'>'.$teams[$i].'</option>'; 
}
?> 
	</select> 
	<input type="submit" value="Submit"> 
</form> 
<?php 
	if($SELECTED_TEAM == -1){
?>
<p>Choose a team!</p>
<?php
} else {
	$team_title = $teams[$SELECTED_TEAM];
?> 
<hr><h2><?php echo $team_title; ?></h2>
<?php 
	}
}
?>
</body>
</html>

Note that in order for me to test it, I used the data files in the attached zip (English leagues).

Come back if you don't understand anything.

Paul 🙂
