I need to update information in a mySQL database and it returns an error.

 

<META HTTP-EQUIV="Refresh"
      CONTENT="0; URL=main_forum.php">

<?php
$host="***********"; // Host name 
$username="***********"; // Mysql username 
$password="***********"; // Mysql password 
$db_name="***********"; // Database name
$tbl_name="forum_answer"; // Table name 

// Connect to server and select databse.
mysql_connect("$host", "$username", "$password")or die("cannot connect"); 
mysql_select_db("$db_name")or die("cannot select DB");

// Get value of id that sent from hidden field 
$id=$_POST['id'];

// Find highest answer number. 
$sql="SELECT MAX(a_id) AS Maxa_id FROM $tbl_name WHERE question_id='$id'";
$result=mysql_query($sql);
$rows=mysql_fetch_array($result);

// add + 1 to highest answer number and keep it in variable name "$Max_id". if there no answer yet set it = 1 
if ($rows) {
$Max_id = $rows['Maxa_id']+1;
}
else {
$Max_id = 1;
}

// get values that sent from form 
$a_name=$_POST['a_name'];
$a_email=$_POST['a_email'];
$a_answer=$_POST['a_answer']; 

$datetime=date("d/m/y H:i:s"); // create date and time 

// Insert answer 
$sql2="INSERT INTO $tbl_name(question_id, a_id, a_name, a_email, a_answer, a_datetime)VALUES('$id', '$Max_id', '$a_name', '$a_email', '$a_answer', '$datetime')";


$tbl_name2="forum_question"; // Switch to table "forum_question" 

// Insert last post 
$sqlmas="UPDATE $tbl_name2 SET lastpost='$datetime', lastpostname='$a_name';

$result2=mysql_query($sql2);

if($result2){
// If added new answer, add value +1 in reply column 
$sql3="UPDATE $tbl_name2 SET reply='$Max_id' WHERE id='$id'";
$result3=mysql_query($sql3);
}
else {
echo "ERROR";
}

mysql_close();
?>

 

I am using a forum script posted here and I'm adding a last post info thing to it.

 

 

PLEASE HELP!

What is the error?

 

Quickly looking at it, I caught this error.

$sqlmas="UPDATE $tbl_name2 SET lastpost='$datetime', lastpostname='$a_name';

 

Change that to

$sqlmas="UPDATE $tbl_name2 SET lastpost='$datetime', lastpostname='$a_name'";

No...you put them at the end of all your mysql_query()'s.

 

Do you see this line?

$result=mysql_query($sql);

 

Change it to

$result=mysql_query($sql)or die(mysql_error());

 

Now change this line

$result2=mysql_query($sql2);

 

To

$result2=mysql_query($sql2)or die(mysql_error());
