Hi,
I'm new to PHP and was wondering if anyone could help me with my problem.
Basically I have an access database and have managed to create a few php scripts by looking at various tutorials and scripts on the net in php that insert, update, delete and view data from the database. The problem is that I need to be able to update, insert and delete more than one row at a time.
For example what I am trying to do at the moment is update an entire column.
I've been trying to use an array to hold the values of one of the database column variables and then just display them to see if I'm getting the right results, which I'm not. :sad:
Can anyone point me in the right direction and/or look at what I've done so far?
<form action="edit1.php" method="post" name="FormName">
<?php
require_once('odbc.php');
//If cmd has not been initialized
if(!isset($cmd))
{
// display all students
$result = odbc_exec($odbc, "SELECT * FROM Students ORDER BY ID");
echo "
<table align=center border=0 cellpadding=5>
<tr bgcolor=#3B6AA0>
<th>ID</th>
<th>FirstName</th>
<th>LastName</th>
<th>Present</th>
</tr>";
//run the while loop that grabs all the students
while($r = odbc_fetch_array($result))
{
//grab the names and the ID of the students
$FirstName=$r["FirstName"]; //take out the first name of student
$LastName=$r["LastName"]; //take out the last name of student
$Present=$r["Present"]; //take out the attendance code
$ID=$r["ID"]; //take out the id
echo "<tr>";
echo "<td><font color=#bbbbbb>$ID</font></td>";
echo "<td>$FirstName</td>";
echo "<td>$LastName</td>";
echo "<td>";
echo "<INPUT TYPE='TEXT' NAME='Present[]' VALUE='$Present' SIZE=3>";
echo "</td>";
// echo "<td><a href='edit1.php?cmd=edit&id=$ID'>Edit</a></td>";
echo "</tr>";
}
echo "</table>";
?>
<input type="submit" name="submit" value="submit">
<?php } ?>
<?php
if ($_POST["submit"])
{
echo $_POST["Present"];
}
?>To actually update the database, I'd use something along the lines of:
<?php
if ($_POST["submit"])
{
$id = $_POST["id"];
$Present = $_POST["Present"];
$sql = "UPDATE Students SET Present='$Present' WHERE ID=$id";
$result = odbc_exec($odbc, $sql);
echo "<br>";
echo "<br>";
echo "Thank you. Information updated.<br>";
echo "<a href='edit1.php'>refresh<a>";
}
}
?>
