Duplicate Database Entries

I need help getting the server validation to work. I'm simply trying stop my database from accepting duplicate entries. The checked entry is not a unique key and the dreamweaver check username behavior doesn't work. Please advise. I'm using the server validation with Validation toolkit and I've followed the advice from the posts on this forum to no avail. The code is below:

<?php require_once('../../Connections/basketball.php'); ?>
<?php require_once("../../WA_DataAssist/WA_AppBuilder_PHP.php"); ?>
<?php require_once("../../WA_ValidationToolkit/WAVT_Scripts_PHP.php"); ?>
<?php require_once("../../WA_ValidationToolkit/WAVT_ValidatedForm_PHP.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;
}
}

$colname_girls_players = "-1";
if (isset($_GET['name'])) {
$colname_girls_players = (get_magic_quotes_gpc()) ? $_GET['name'] : addslashes($_GET['name']);
}
mysql_select_db($database_basketball, $basketball);
$query_girls_players = sprintf("SELECT * FROM girls_players WHERE name = %s", GetSQLValueString($colname_girls_players, "text"));
$girls_players = mysql_query($query_girls_players, $basketball) or die(mysql_error());
$row_girls_players = mysql_fetch_assoc($girls_players);
$totalRows_girls_players = mysql_num_rows($girls_players);?>

the recordset is filtering on the name Query sting variable instead of the name From post.

Set the filtering up as:
'name' '='
'Form variable' 'name'

Not Working

I tried and changed to form variable. Still not working. Any other suggestions

change:

php:
$WAFV_Errors .= WAValidateNM($totalrows_girls_players['name'] . "",-1,0,"",",.",false,1);



to:

php:
$WAFV_Errors .= WAValidateNM($totalrows_girls_players . "",-1,0,"",",.",false,1);

Sorry still not working. It still inserts the same name. Next suggestion? Thx for helping

case sensitivity. the line that sets the total rows variable is:

php:
$totalRows_girls_players = mysql_num_rows($girls_players);



you need to use the same case in the server validations.

change:

php:
$WAFV_Errors .= WAValidateNM($totalrows_girls_players . "",-1,0,"",",.",false,1);




to:

php:
$WAFV_Errors .= WAValidateNM($totalRows_girls_players . "",-1,0,"",",.",false,1);

this sort of validation is not supported in a multiple insert behavior.


with multiple insert the form elements are dynamically named.

This will require extensive unsupported hand coding to make work.
