Hi. I used Greaeme Merrall's tutorial to make a php form.
My host did something with php, and now this script doesn't work anymore.
They said it had something to do with register_globals to do, but after I
turned
Register_Globals on, this script still doesn't work. (It worked before)
This script should make it possible to add, list, edit and delete a record
from database.
Now this script is ONLY listing the record, not deleting or anything else.
Please help!
Here's the script from Graeme Merrall:
<html>
<body>
<?php
$db = mysql_connect("localhost", "root");
mysql_select_db("mydb",$db);
if ($submit) {
// here if no ID then adding else we're editing
if ($id) {
$sql = "UPDATE employees SET
first='$first',last='$last',address='$address',position='$position' WHERE
id=$id";
} else {
$sql = "INSERT INTO employees (first,last,address,position) VALUES
('$first','$last','$address','$position')";
}
// run SQL against the DB
$result = mysql_query($sql);
echo "Record updated/edited!<p>";
} elseif ($delete) {
// delete a record
$sql = "DELETE FROM employees WHERE id=$id"; $result = mysql_query($sql);
echo "$sql Record deleted!<p>";
} else {
// this part happens if we don't press submit
if (!$id) {
// print the list if there is not editing
$result = mysql_query("SELECT * FROM employees",$db);
while ($myrow = mysql_fetch_array($result)) {
printf("<a href=\"%s?id=%s\">%s %s</a> \n", $PHP_SELF, $myrow["id"],
$myrow["first"], $myrow["last"]);
printf("<a href=\"%s?id=%s&delete=yes\">(DELETE)</a><br>", $PHP_SELF,
$myrow["id"]); }
}
?>
<P>
<a href="<?php echo $PHP_SELF?>">ADD A RECORD</a>
<P>
<form method="post" action="<?php echo $PHP_SELF?>">
<?php
if ($id) {
// editing so select a record
$sql = "SELECT * FROM employees WHERE id=$id";
$result = mysql_query($sql);
$myrow = mysql_fetch_array($result);
$id = $myrow["id"];
$first = $myrow["first"];
$last = $myrow["last"];
$address = $myrow["address"];
$position = $myrow["position"];
// print the id for editing
?>
<input type=hidden name="id" value="<?php echo $id ?>">
<?php }
?>
First name:<input type="Text" name="first" value="<?php echo $first
?>"><br>
Last name:<input type="Text" name="last" value="<?php echo $last ?>"><br>
Address:<input type="Text" name="address" value="<?php echo $address
?>"><br>
Position:<input type="Text" name="position" value="<?php echo $position
?>"><br>
<input type="Submit" name="submit" value="Enter information">
</form>
<?php
}
?>
</body>
</html>
