Hello,
I was just wondering how to update data to database from html text field.
I have a form that retrieves data from dbase and put's values into text field in a web page. I want to be able to modify data and then save it dbase by hitting save button (also form object).
ie.
$sql="SELECT col1 FROM table WHERE id = 1"; $result=mysql_query($sql); $num = mysql_num_rows($result); $row = mysql_fetch_array($result); $var = $row["col1"]; echo "<form name=\"form1\" method=\"post\" action=\"\">";
echo "<input name=\"name\" type=\"text\" id=\"name\" value=\"$var1\" size=\"30\" maxlength=\"30\">";
echo "<input name=\"save\" type=\"submit\" id=\"save\" value=\"save\">";
Anyone know what is the proper way to do this?

You need to capture the values passed by the form in the script referenced in the form action attribute, using the relevant superglobal referenced in the form method attribute (e.g. $_GET or $_POST).
Using your example, you would access the "name" form element like so:
$_POST['name']
Then you should use this variable in an UPDATE or INSERT statement and send that to your database server, e.g.:
mysql_query("UPDATE table SET col1 = " . $_POST['name'] . " WHERE id = " . $_POST['id'] . " LIMIT 1");
I would suggest reading the PHP manual a little more carefully, in particular those sections regarding variable and form handling, as well as the section on MySQL.

David
