implode() MySql Query not working - php

Question

I am trying to implode some variables and insert them into a MySql database, but for some reason it is not working. I have been trying for hours and I''m just not sure what I'm doing wrong.
If you can help it would be much appreciated.
$AddressString = "address1,address2,address3,address5,postcode";
$AddressSplit = explode( ",", $AddressString ); //split the address string
$StringLength = count( $AddressSplit ) - 1;
$s = 0; //trim any white spaces from the address string
while ( $s < count( $AddressSplit ) ) {
$AddressSplit[$s] = trim( $AddressSplit[$s] );
$s++;
}
//Create the Values to insert into DB
$MysqlValues = implode( "','", $AddressSplit );
$MysqlValues = "'$MysqlValues'";
$NumberVals = count( $AddressSplit );
$t = 1;
while ( $t < $NumberVals ) {
$ad[$i] = "add$i";
$t++;
}
$TableNames = implode( ", ", $ad );
mysql_query( "INSERT INTO pstc_add_main (" . $TableNames . ",add10,date)
VALUES (" . $MysqlValues . ",'$cdate')" );
}

Answer 1

Because you start making the field names 1 based, your are one field short!
In the end you must end with a equal number of fields and values.
Try this:
$t = 0;
while ( $t < $NumberVals ) {
$ad[$i] = "add$i";
$t++;
}
Or, if you do not want the first field to be "add", change it like this:
$t = 1;
while ( $t <= $NumberVals ) {
$ad[$i] = "add$i";
$t++;
}
Of course, it would have been a easy test to do:
$sql = "INSERT INTO pstc_add_main (" . $TableNames . ",add10,date)
VALUES (" . $MysqlValues . ",'$cdate')";
var_dump($sql);
mysql_query($sql);

Not tested,
I doubt you change,
$MysqlValues = implode("','", $AddressSplit);
to
$MysqlValues = implode(",", $AddressSplit);

Answer 3

Just use
$MysqlValues = implode( ",", $AddressSplit );
and try to edit the code like
mysql_query( "INSERT INTO pstc_add_main (".$TableNames." ,add10,date)
VALUES (" . $MysqlValues . ",$cdate)" );
