Question

I’m trying to enter a value in a specific records , I have a code where the user select a course from a drop down list then add students from a table through check-box to the course , the thing is when I’m trying to insert the course ID into the student table i cant choose the students that the user choose !!
here is my code :

<?php

include("S.php");
$connectdb = mysql_connect('localhost','root','sara') or die ("Not Connect");
if (!$connectdb)
{
    die('Could not connect :'. mysql_errno());
}
$selestdb = mysql_select_db('iexa', $connectdb) or die ("not selected database");
$count = count($foo);

for ($i = 0; $i <= $count; $i++){
    $Student = $foo[$i];
    $res = mysql_query("SELECT St_ID FROM student WHERE St_ID='$Student'");
    while($row = mysql_fetch_array($res))
    {
        $sql ="INSERT INTO student (ID) VALUES ('$_POST[$row['courseID'] . "]')";
    }
}
if (!mysql_query($sql,$connectdb))
{
   die ('Error :'.mysql_error());
}
echo "The Students are add to the course <br />";
mysql_close($connectdb) ;

?>

where $foo is the array that contain the students ID that were chosen to add to the course
this is the error that i got :
Parse error: syntax error, unexpected ‘[‘, expecting ‘]’ in C:\AppServ\www\test\S2.php on line 20

Answer 1

The error is here:

$sql ="INSERT INTO student (ID) VALUES ('$_POST[$row['courseID'] . "]')";

It should be:

$sql = "INSERT INTO student (ID) VALUES ('" . $_POST[$row['courseID']] . "')";
