在mysql中插入多个复选框

Question

So i would like to insert multiple checkbox into mysql but cant figured it ou how.

Selecting from database and inserting:

$editFormAction = $_SERVER['PHP_SELF'];
if (isset($_SERVER['QUERY_STRING'])) {
$editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);
}

if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "form1")) {
$insertSQL = sprintf("INSERT INTO tournamenteams (id, id_tournament, id_team) VALUES (%s, %s, %s)",
   GetSQLValueString($_POST['id'], "int"),
   GetSQLValueString($_POST['id_tournament'], "int"),
   GetSQLValueString($_POST['id_team'], "int"));


mysql_select_db($database_searchon, $searchon);
$Result1 = mysql_query($insertSQL, $searchon) or die(mysql_error());
}

And now i created a form and inside the form theres the checkbox. i select database records and show it on multiple checkbox and then what i want to do is selecting the checkboxs i want it and insert it all when i submit the form, but its only submit the first checkbox i mark.

Form:

<form action="<?php echo $editFormAction; ?>" method="post" name="form1" id="form1">
<select name="id_tournament">
<?php 
do {  
?>
<option value="<?php echo $row_tournaments['id_tournament']?>" ><?php echo $row_tournaments['id_tournament']?></option>
<?php
} while ($row_tournaments = mysql_fetch_assoc($tournaments));
?>
</select>
<?php do { ?>
<?php echo $row_teams['id_team']?>:<input type="checkbox" name="id_team" value="<?php echo $row_teams['id_team']?>" />
<?php } while ($row_teams = mysql_fetch_assoc($teams)); ?>
<input type="submit" value="Insert record" />
<input type="hidden" name="id" value="" />
<input type="hidden" name="MM_insert" value="form1" />
</form>

Checkbox:

<?php do { ?>
<?php echo $row_teams['id_team']?>:<input type="checkbox" name="id_team" value="<?php echo $row_teams['id_team']?>" />
<?php } while ($row_teams = mysql_fetch_assoc($teams)); ?>

Entire Code for a better view:

<?php require_once('Connections/searchon.php'); ?>
<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "") 
{
if (PHP_VERSION < 6) {
$theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
}

$theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);

switch ($theType) {
case "text":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;    
case "long":
case "int":
$theValue = ($theValue != "") ? intval($theValue) : "NULL";
break;
case "double":
$theValue = ($theValue != "") ? doubleval($theValue) : "NULL";
break;
case "date":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
case "defined":
$theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
break;
}
return $theValue;
}
}

$editFormAction = $_SERVER['PHP_SELF'];
if (isset($_SERVER['QUERY_STRING'])) {
$editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);
}



if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "form1")) {
$insertSQL = sprintf("INSERT INTO tournamenteams (id, id_tournament, id_team) VALUES (%s, %s, %s)",
   GetSQLValueString($_POST['id'], "int"),
   GetSQLValueString($_POST['id_tournament'], "int"),
   GetSQLValueString($_POST['id_team'], "int"));


mysql_select_db($database_searchon, $searchon);
$Result1 = mysql_query($insertSQL, $searchon) or die(mysql_error());
}

mysql_select_db($database_searchon, $searchon);
$query_tournamenteams = "SELECT * FROM tournamenteams";
$tournamenteams = mysql_query($query_tournamenteams, $searchon) or die(mysql_error());
$row_tournamenteams = mysql_fetch_assoc($tournamenteams);
$totalRows_tournamenteams = mysql_num_rows($tournamenteams);

mysql_select_db($database_searchon, $searchon);
$query_tournaments = "SELECT * FROM tournaments";
$tournaments = mysql_query($query_tournaments, $searchon) or die(mysql_error());
$row_tournaments = mysql_fetch_assoc($tournaments);
$totalRows_tournaments = mysql_num_rows($tournaments);

mysql_select_db($database_searchon, $searchon);
$query_teams = "SELECT * FROM teams";
$teams = mysql_query($query_teams, $searchon) or die(mysql_error());
$row_teams = mysql_fetch_assoc($teams);
$totalRows_teams = mysql_num_rows($teams);
?>

mysql_free_result($tournaments);

mysql_free_result($teams);

PS: Im using dreamweaver since im still starting coding :)

Any help will be appreciated,

Answer 1

In order to have PHP to receive every checkbox value (in an array, naturally) is to put [] at the end of the group's name. So, the part where you create the checkboxes should be changed to:

<?php do { ?>
<?php echo $row_teams['id_team']?>:<input type="checkbox" name="id_team[]" value="<?php echo $row_teams['id_team']?>" />
<?php } while ($row_teams = mysql_fetch_assoc($teams)); ?>

Notice that the only change was in name="id_team[]".
