Solved - Preventing Duplicates Entries per User

I needed to limit user records to 10 and prevent duplicate entries for that specific user. Here's how I modified the hooks file for the table in question:
Code: Select all
function tableMain_before_insert(&$data, $memberInfo, &$args) {
$mi = getMemberInfo();
$recordCount=sqlvalue("SELECT count(1) FROM `membership_userrecords` where memberID='".$mi['username']."' and tableName='tableMain'");
$lookupIDCompare = $data['lookupID'];
$maintablename = 'tableMain';
$countReturn = TRUE;
// check the current value submitted and compare vs query results, or if query results > 0 then it's a duplicate.
$duplicateCheck = sqlvalue("SELECT count(1) from lookupTable WHERE ID = $lookupIDCompare AND ID in (SELECT lookupID FROM membership_userrecords JOIN tableMain ON membership_userrecords.pkValue = tableMain.ID WHERE tableMain.ID IN (SELECT pkValue from membership_userrecords WHERE memberID='".$mi['username']."' AND tableName = '$maintablename' ))");
if ($duplicateCheck > 0) {
$countReturn = FALSE; }
// limit entries to 10
if ($recordCount > 9) {
$countReturn = FALSE; }
return $countReturn;
// return TRUE; (default value)
}
I still haven't figured out how to present custom error messages but at least it's working. If anybody else is stuck with this issue I hope this helps!

Thanks! I forgot to note that this fix is used when you have a lookup table and want to use the unique ID to check for a duplicate instead of the value string.

I have tried to implement that code in my application and I have not been able to make it work for me. Here is the file with the name of the fields. Let's see if someone can help me, I would appreciate it.
Thanks in advance.
********************************************************
Table = 'Vientres'
primary key = 'ID'
Field 'CODIGO' is the field that should not be repeated
*********************************************************
function Vientres_before_insert(&$data, $memberInfo, &$args) {
$mi = getMemberInfo();
$recordCount=sqlvalue("SELECT count(1) FROM `membership_userrecords` where memberID='".$mi['username']."' and tableName='Vientres'");
$lookupIDCompare = $data['ID'];
$maintablename = 'Vientres';
$countReturn = TRUE;
// check the current value submitted and compare vs query results, or if query results > 0 then it's a duplicate.
$duplicateCheck = sqlvalue("SELECT count(1) from Vientres WHERE Vientres.ID = $lookupIDCompare AND membership_userrecords.ID in (SELECT lookupID FROM membership_userrecords JOIN Vientres ON membership_userrecords.pkValue = Vientres.ID WHERE Vientres.ID IN (SELECT pkValue from membership_userrecords WHERE memberID='".$mi['username']."' AND tableName = '$maintablename' ))");
if ($duplicateCheck > 0) {
$countReturn = FALSE; }
return $countReturn;
// return TRUE; (default value)
}

function Vientres_before_insert(&$data, $memberInfo, &$args) {
Without further investigation: I don't think this ID is available BEFORE insert
You are using this after the following line:
Did you check the value?
I strongly recommend
var_dump()
-ing variable values before using them unverified.
