Inserting variables Error

almystersv · February 11, 2008

Hi Guys,

I am gettins stuck on this section of my website. Its function is to alocate users specific tasks. At the moment though, the code does not seem to carry across the variables 'taskID', 'empID', emptaskweekDay'. As i am getting the error message "Unable to perform query

insert into emptask values ('','','','N')"

It is probably something very simple but I have tried a number of things and cannot get it to work.

Here is my taskadmin page code

<?php
session_start();
if (isset($_SESSION['username']) == false && ($_SESSION['type']) == 'user' && ($_SESSION['type']) == 'manager'){
	header("Location: login.php");
	exit();
}
require "connect.php";

$query = "select * from task where weekday = 'Monday' OR weekday = 'Everyday' ORDER BY taskID";
$result = mysql_query($query, $connection) or die ("Unable to perform query $query");

$query2 = "select * from employee where active = 'y'";
$result2 = mysql_query($query2, $connection) or die ("Unable to perform query $query2");
?>

	while ($row2 = mysql_fetch_array($result2))
  		$employee_list .= '<option>'.$row2['fName'].' '.$row2['sName'].'</option>';
	$employee_list .= '</select>';

	while($row = mysql_fetch_array($result)) 
	{ ?>
  		<tr>
    		<td height="27"><?php echo $row['taskName']; ?></td>
    		<td><?php echo $row['taskDescription']; ?></td>
		<td><?php echo $row['weekday']; ?></td>
		<td>
		<form><?php echo $employee_list; ?></form></td>
  		</tr>
	<?php } ?></td>
  	</tr>
</table>
<form action="taskAdminQuery.php">
<input name="Save" type="submit" value="Allocate Tasks" />
</form>
</div>
</body>
</html>

Here is my taskAdminQuery code

<?php
require "connect.php";
//$empName = $_GET['empName'];
$empID = $_GET['empName'];
$emptaskweekDay = $_GET['weekday'];
$taskID = $_GET['taskID'];

$query =  "insert into emptask values ('".$taskID."','".$empID."','".$emptaskweekDay."','N')";
$result = @mysql_query($query, $connection) 
or die ("Unable to perform query<br>$query");

$message1 = "Tasks Allocated Successfully.";
header("Location: TaskAdmin.php?message1=$message1");
exit();
//}
?>

Any help will be greatly appreciated.

Thanks

Your Problem is HERE

<?php $query =  "insert into emptask values ('".$taskID."','".$empID."','".$emptaskweekDay."','N')"; ?>

Should be

<?php $query =  "INSERT INTO `emptask` (`field1`,`field2`,`field3`,`field4`) VALUES ('$taskID','$empID','$emptaskweekDay','N')"; ?>

Replace Field1, Field2,Field3,Field4 with your mysql fields, each value asigned to the field in the order given for both sides.

this just made me laugh

<?php
$query =  "insert into emptask values ('".$taskID."','".$empID."','".$emptaskweekDay."','N')";
$result = @mysql_query($query, $connection) 
or die ("Unable to perform query<br>$query");
?>

@ to suppress it but then an or die to push the error ?

And Some Good Resources Next Time:

Note: As Cooldude(still laughing) said, you should add a

or die(mysql_error());

to "push" the error right out of the query, and into the browser.

this is the error that is gettin spat back

Error:Cannot add or update a child row: a foreign key constraint fails (`bisportal/emptask`, CONSTRAINT `emptask_ibfk_3` FOREIGN KEY (`taskID`) REFERENCES `task` (`taskID`))

InnoDB also supports foreign key constraints. The syntax for a foreign key constraint definition in InnoDB looks like this:

InnoDB rejects any INSERT  or UPDATE operation that attempts to create a foreign key value in a child table if there is no a matching candidate key value in the parent table.

hi

I have removed the primary key and foreign key constraints in my database and now it is working!

Thanks

I cannot seem to find a "topic solved" button anywhere!?

lol, don't worry man, there was a forum update 2 days ago I think, so that button is not functional for the moment. Just Modify your post if possible, and put a giant TOPIC SOLVED text.
