I need help with Php forms. I am trying to insert at least 2 & a Max of 3 team players data to MySQL for registration purposes.

By using a loop to get the 3 form values and iterate until data is stored in the tables

First Table is Players table: columns names are as follows.

playerid, playerfirstname, playerlastname, playerdob, playernationalranking, playerphonenumber, playeremailaddress, playerpassportnumber,playerplayinghistory, playeraddress, playercountry

Second Table is Participants table: columns names are as follows.

playerid, participtionid, championshipid, countryid, created_at, status (is deleted or not) , room_booking_status

Third Table is Photo links

Time, FileLocation, IP, idUsers, playerid

on top of that, another i need to insert to a 4th table and its teamplayers table: column names are as follows.

Teamid, participtionid, countryid, idplayer1, idplayer2, idplayer3, TimeStamp

PHP code starts as follows:

if (!isset($_SESSION)) {
$editFormAction = $_SERVER['PHP_SELF'];
    if (isset($_SERVER['QUERY_STRING'])) {
      $editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);
$colname_numRows = "-1";
    if (isset($_SESSION['MM_UserGroup'])) {
      $colname_numRows = $_SESSION['MM_UserGroup'];
if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "form1")) {

        for($i=1;$i<4;$i++) {

        // combining date of birth
        $playerDob = $_POST['year'.$i]."-".$_POST['month'.$i]."-".$_POST['day'.$i];
        $playerDob = mysql_real_escape_string($playerDob);
          // first query
          $insertPlayerInfo = sprintf("INSERT INTO players (playerid, playerfirstname, playerlastname, playerdob, playernationalranking, playerphonenumber, playeremailaddress, playerpassportnumber, playerplayinghistory, playeraddress, playercountry) VALUES ('', %s, %s, '$playerDob', %s, %s, %s, %s, %s, %s, %s)",
        GetSQLValueString(str_replace('\' ', '\'', ucwords(str_replace('\'', '\' ', strtolower($_POST['playerFirstName'.$i])))), "text"),
        GetSQLValueString(str_replace('\' ', '\'', ucwords(str_replace('\'', '\' ', strtolower($_POST['playerLastName'.$i])))), "text"),

            $_SESSION['playerid'.$i] = mysql_insert_id($EntrySystem) or die(mysql_error());

        // second query 
            $insertSQL = sprintf("INSERT INTO participants (playerid, participationid, championshipid, countryid, created_at, status, room_booking_status) VALUES ('".$_SESSION['playerid'.$i]."','', %s, %s, %s, '1', '0')",

                        function savedata(){

                        $putItAt = "upload/".$_SESSION['MM_Username']."/" .sha1(rand())."-" .basename($_FILES['uploadedfile'.$i]['name']);

                        $putItAt = str_replace("php", "txt" , $putItAt);

        $insertGoTo .= $_SERVER['QUERY_STRING'];
      header(sprintf("Location: %s", $insertGoTo));




the HTML form is at the same page of the above php code

<form enctype="multipart/form-data" method="post" name="form1" action="<?php echo $editFormAction; ?>">

        <td align="center">

    } while ($row_availableChampionships = mysql_fetch_assoc($availableChampionships));
    // First table for selecting Championship

This code looks 10 years old. Where did you get it?

It's using deprecated mysql_* functions, global variables, getsqlvaluestring with sprintf . This is all a nightmare, basically designed to avoid SQL injection. If you use mysqli or PDO, all this nonsense can be avoided.

ALso don't run a query on each iteration of the for loop, rather build up the query and run ONE query after exit of loop.
