PHP - Selecting From Mysql Populated Checkbox List?

Ok, so I've spent quite a bit of time piecing together this solution from a variety of sources. As such, I may have something in my code below that doesn't make sense or isn't neccessary. Please let me know if that is the case.

I'm creating an administrative form that users will you to add/remove items from a MySQL table that lists open positions for a facility. The foreach loop generates all of the possible job specialties from a table called 'specialty_list'. This table is joined to a second table ('open_positions') that lists any positions that have been selected previously.

Where I'm stuck is getting the checkbox to be checked if the facility_ID from the open_positions table matches the $id passed in the URL via ?facility_id=''. Here's where I am so far:


$query = "SELECT specialty_list.specialty_displayname
 , specialty_shortname
     , open_positions.position
     , facility_ID
  FROM specialty_list
LEFT OUTER
  JOIN open_positions
    ON open_positions.position = specialty_list.specialty_shortname
ORDER 
    BY specialty_list.specialty_shortname";

$results = mysql_query($query) or die(mysql_error());

while($row = mysql_fetch_assoc($results)) 
{ 
$positions[$row['specialty_shortname']] = $row['specialty_displayname'];
}

echo "<form method='POST' action='checkbox.php'>";
foreach($positions as $specialty_shortname => $specialty_displayname) 
{
$facility_ID = $row['facility_ID'];
  
$checked = $facility_ID == $row['facility_ID'] ? ' checked' : ''; 

echo "<input type='checkbox' name='position[]' value=\"{$specialty_shortname}\"{$checked}>&nbsp;&nbsp;{$specialty_displayname}</input><br/>"; 

}  
echo "<input type='hidden' name='facility_ID' value='$id'>";
echo "<input type='submit' value='Submit Checkboxes!'>";
echo "</form>";


Any ideas how to get this working? I feel like I'm very close, but I just can't get it. I also tried starting from scratch with a WHILE statement instead of a FOREACH, but haven't tweaked it enough to prevent duplicate checkboxes. With that in mind, here it is, just in case that's a better direction:


$query = "SELECT specialty_list.specialty_displayname
 , specialty_shortname
     , open_positions.position
     , facility_ID
  FROM specialty_list
LEFT OUTER
  JOIN open_positions
    ON open_positions.position = specialty_list.specialty_shortname
ORDER 
    BY specialty_list.specialty_shortname";

$results = mysql_query($query) or die(mysql_error());

echo "<form method='POST' action='checkbox.php'>";

while($row=mysql_fetch_assoc($results))
{ 
$facility_ID = $row['facility_ID'];
$specialty_shortname = $row['specialty_shortname'];
$specialty_displayname = $row['specialty_displayname'];


if ($facililty_ID==$id) {

$checked=' checked';
}

echo "<input type='checkbox' name='position[]' value=\"$specialty_shortname\"$checked>&nbsp;&nbsp;$specialty_displayname</input><br/>"; 
}

echo "<input type='hidden' name='facility_ID' value='$id'>";
echo "<input type='submit' value='Submit Checkboxes!'>";
echo "</form>";

Hey guys, I can't wrap my head around how to make this work right...

I have three tables:
Code: [Select]
CREATE TABLE `games` (
  `g_id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(150) DEFAULT NULL,
  PRIMARY KEY (`g_id`));

CREATE TABLE IF NOT EXISTS `game_player` (
  `r_id` int(11) NOT NULL AUTO_INCREMENT,
  `p_id` int(11) DEFAULT NULL,
  `g_id` int(11) DEFAULT NULL,
  `bool` int(1) NOT NULL DEFAULT '0',
  PRIMARY KEY (`r_id`));

CREATE TABLE IF NOT EXISTS `players` (
  `p_id` int(11) NOT NULL AUTO_INCREMENT,
  `playerid` varchar(150) NOT NULL,
  PRIMARY KEY (`p_id`),
  UNIQUE KEY `playerid` (`playerid`));

The players table is my list of users, and they're tied to the list of games via the game_player table.

So here's my issue... I'm trying to show the full list of games, and then check mark each record where the player does play it. 
This is what I have so far - it shows all the games,  but it's not checking the boxes.

Code: [Select]
$result = mysql_query("SELECT * FROM games") or die(mysql_error());
while($row = mysql_fetch_array($result))
{
$newquery = "SELECT * FROM game_player, players
WHERE game_player.p_id = players.p_id
AND game_player.g_id = ".$row['g_id']. "
AND players.playerid = {$userid}";
$query = mysql_query($newquery) or die(mysql_error());
if($query['bool'] == 1) { $set_checked = " CHECKED";
}
else{ $set_checked = "";
}
echo "<input type=\"checkbox\" name=\"box1\" value=\"".$query['g_id']."\"" . $set_checked . "/>".$row['name']."<br />\n";
}

Hey--I'm new to the forum, to php, and to web development in general.  I am using php to populate a drop-down list from a MySQL database, and then echo the text in a field associated with the selected value below.  I'm having no trouble creating the drop-down list, but I can't figure out how to echo the associated field below, or the ?Abbreviation=value that I expected in the url.

Here is the php file:

Code: [Select]
<!DOCTYPE HTML>
<html>
<head>
</head>
<body>

<form name="form" method="GET" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<select>
<?php

$con = mysql_connect("localhost","root","root");

if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("calculators", $con);

$result = mysql_query("SELECT * FROM calculator");

while($row = mysql_fetch_array($result))
  {
echo "<option type='text' name='Title' " . "value='" . $row['Title'] . "'>" . $row['Abbreviation'] . "</option>";
  }
mysql_close($con);
?>
</select>
<br>
<input type="submit" name="submit">
</form>
   
<?php echo $_GET['Title']; ?>

</body>
</html>

This is what the source code looks like in the browser:

Code: [Select]
<!DOCTYPE HTML>
<html>
<head>
</head>
<body>

<form name="form" method="GET" action="/calculators/index.php">
<select>
<option type='text' name='Title' value='Mean Arterial Pressure'>MAP</option><option type='text' name='Title' value='Body Mass Index'>BMI</option></select>
<br>
<input type="submit" name="submit">
</form>
   

</body>
</html>

And this is appearing in the url after I press submit:

Code: [Select]
?submit=Submit

I'm sorry if this is a silly question, or if I'm being long-winded in asking it.  I'm very new to web development, and I'm not sure exactly what information is necessary to solve the problem.  Also, though changes to the code are helpful, I may need an explanation to understand them...

Thanks,

Davis

I have a form that contains 3 text fields and 7 populated lists (that are dependent on the choice of the previous lists).  When I post the information to MySQL and to my processing page, it posts the table "ids" instead of the selected option. 

Here's the php code for the form:

<form action="gccsuccess_form.php" method="post" enctype="multipart/form-data" name="gcc" id="gcc">
  <table width="700" border="0" align="center" cellpadding="3" cellspacing="3">
    <tr>
      <td><label for="date">Today's Date:</label>
 <input type="text" name="date" id="date"></td>
      <td>&nbsp;</td>
    </tr>
    <tr>
      <td>Week Number:
       <select name="week" size="1" id="week">
         <option value="0" selected>Week 0 - 3/26 - 4/1</option>
         <option value="1">Week 1 - 4/2 - 4/8</option>
         <option value="2">Week 2 - 4/9 - 4/15</option>
         <option value="3">Week 3 - 4/16 - 4/22</option>
         <option value="4">Week 4 - 4/23 - 4/29</option>
         <option value="5">Week 5 - 4/30 - 5/6</option>
         <option value="6">Week 6 - 5/7 - 5/13</option>

And here's the code for the page it is posted in:

<?php
      
      $date = $_POST['date'];
      $week = $_POST['week'];
      $location = $_POST['location'];
      $team_name = $_POST['team_name'];
      $capt = $_POST['capt'];
      $mem_2 = $_POST['mem_2'];
      $mem_3 = $_POST['mem_3'];
      $mem_4 = $_POST['mem_4'];
      $mem_5 = $_POST['mem_5'];
      $steps_1= $_POST['steps_1'];
      $steps_2= $_POST['steps_2'];
      $steps_3= $_POST['steps_3'];
      $steps_4 = $_POST['steps_4'];
      $steps_5 = $_POST['steps_5'];
      
      mysql_connect("mysql1.myregisteredsite.com", "49200_kandace", "Leonardo56")
      or die(mysql_error());
      mysql_select_db("49200_GCC") or die(mysql_error());
      mysql_query("INSERT INTO `walkathon` VALUES ('$date', '$week', '$location', '$team_name', '$capt','$mem_2','$mem_3',  '$mem_4', '$mem_5', '$steps_1','$steps_2', '$steps_3','$steps_4', '$steps_5' )"); 

      Print "Thank you for your entry. <br>
      Report summary: <br/><br/>";    
      
         echo "<strong> Date: </strong>   {$date} 
         <br/> <br/><strong> Week: </strong>   {$week}
         <br/> <br/><strong> Location: </strong>  {$location}
         <br/> <br/><strong> Team Name: </strong>   {$team_name}
         <br/> <br/><strong> Team Captain: </strong>  {$capt} / <strong> Steps: </strong> {$steps_1} 
         <br /> <br/><strong> Team Member 2 Name: </strong>  {$mem_2} / <strong> Steps: </strong> {$steps_2} 
         <br /> <br/><strong> Team Member 3 Name: </strong>  {$mem_3} / <strong> Steps: </strong> {$steps_3}
         <br /> <br/><strong> Team Member 4 Name: </strong>  {$mem_4} / <strong> Steps: </strong> {$steps_4}
         <br /> <br/><strong> Team Member 5 Name: </strong>  {$mem_5} / <strong> Steps: </strong> {$steps_5}"
         
               ?>

How do I get the processing page to echo the selected option instead of the id?
