Construct your INSERT a piece at a time. Something like:
$sql = "INSERT INTO $myanet02
(staffdev,strategies,rules,news,information,policies) VALUES(";
for($i=0;$i<count($category);$i++) {
if($HTTP_POST_VARS["category{$i}"] == 'yes') {
$sql .= "\'$email\',";
}
else {
$sql .= "NULL,";
}
}
$sql = substring($sql,0,-1).")";
//$query = mysql_query($sql,$connect) or die(mysql_error());
echo $sql;

Subject: [PHP-DB] looped insert
Hi everyone:
I've been fiddling with this all day, and well - if it was working you
wouldn't be reading this right now! ;-)
My script should take the selections made by users and process them via
straightforward MySQL inserts:
//Get all table column names, dynamically display them as checkboxes. Use to
process subscriptions:
$fields = mysql_list_fields("$dbName", "myanet_categories", $connect);
$columns = mysql_num_fields($fields);
for ($i=0; $i<$columns; $i++) {
$names = mysql_field_name($fields, $i) . "\n";
$catselect .= "<b>$names </b><input type=\"checkbox\"
name=\"category[$names]\" value=\"yes\"><br>\n";
}
//If submit button selected, process those ticked checkbox categories:
if(isset($submit)) {
//loop while categories have been ticked
for($i=0;$i<count($category);$i++) {
if($HTTP_POST_VARS["category{$i}"] == 'yes') { //Not sure
about this bit...
$sql = "INSERT INTO $myanet02
(staffdev,strategies,rules,news,information,policies)
VALUES('$email','$email','$email','$email','$email','$email')";
//$query = mysql_query($sql,$connect) or
die(mysql_error());
echo $sql;
}
}
}
At the moment not even echoing my $sql works. I know this aint gonna work as
it is, because what I really need to know is:
* How do I insert into only those categories that have been checked?
(default is 'null' in a VARCHAR(50) field)
* How do I only declare '$email' a single time as this is the only value
being inserted?
Many thanks:
Russ
