:suicide:  This is me at this point.. not really but I do need some help, Im trying to complete a project, it was supposed to be a group project but with only 6 people in class we opted to try to figure it out on our own.. anyway.. I cannot get my Start/End DATE field to update or insert? 

http://www.ctcsports.org/upload/Fall2013/CIST2352/900104329/Assignment33/view_contracts.php

my file to create the table

// Create a MySQL table in the selected database
$sql = "DROP TABLE IF EXISTS dRcontract";
mysql_query($sql);
mysql_query("CREATE TABLE `dRcontract` (
 `cid` int(11) NOT NULL auto_increment,
 `pid` int(11) NOT NULL,
 `tid` int(11)  NOT NULL,
 `Nickname` VARCHAR(50),
  `StartDate` DATE,
  `EndDate` DATE,
  `PlayerSalary` decimal,
 
 PRIMARY KEY (`cid`),
 UNIQUE (`pid`),
 UNIQUE (`tid`)

)")
or die(mysql_error());  

echo "Table Created!";

?>

Here is the contract_model.php file

<?php
        /*
                Allows the user to both create new model and edit existing model
        */

        // connect to the database
        include("connect-db.php");
        
					
				
				
					
					//PlayerSalary decimal

        // creates the new/edit record form
        // since this form is used multiple times in this file, I have made it a function that is easily reusable
        function renderForm($pid = '', $tid ='', $Nickname = '', $StartDate = '',$EndDate = '', $PlayerSalary = '', $error = '', $cid = '')
        { ?>

if ($stmt = $mysqli->prepare("INSERT dRcontract (pid, tid, Nickname, StartDate, EndDate,PlayerSalary) VALUES (?, ?, ?, ? ,?, ?)"))

Should be: 

if ($stmt = $mysqli->prepare("INSERT INTO dRcontract (pid, tid, Nickname, StartDate, EndDate,PlayerSalary) VALUES (?, ?, ?, ? ,?, ?)"))

I would suggest as cyber says and output the error to find out exactly where it is failing.

you are doing no check at all that the values being passed in for start and end dates are in the expected format. You need to make sure that the dates are in the Y-m-d format. So 5th jan 2013 would be 2013-01-05. If you dont pass a correctly formatted date into the query it will not insert

The bind values for the $StartDate and $EndDate, I think need to be s not i

// bind params for update
$stmt->bind_param("iisssii", $pid, $tid, $Nickname, $StartDate, $EndDate, $PlayerSalary, $id);

// bind params for new record
$stmt->bind_param("iisssi", $pid, $tid,$Nickname, $StartDate, $EndDate, $PlayerSalary);

Thanks so much. Like I said above I have some household things to do but I will be back in a little bit, as you can see I have many issues with my program.. I really look up to those of you that have learned this so well,… I hope to be of some help in the future.. :-)
