I am guessing that you have a table of values and you want to be able to edit
those values one by one until every row has been edited? Consider something
like this:
<?
$q = mysql_query("select id, field from table where
status = 'new' order by id desc limit 1");
while ($r = mysql_fetch_array($q)){
print "<form action='$_SERVER[PHP_SELF]'>";
print "<input type='text' name='field' value='$r[field]' />";
print "<input type='hidden' name='id' value='$r[id]' />";
print "<input type='submit' value='Save value' />";
print "</form>";
}
?>
This will present a form to edit the last entry in the database. You could of
course edit multiple fields at the same time:
<form action='<?=$_SERVER[PHP_SELF] ?>'>
<?
$q = mysql_query("select id, field from table where
status = 'new' order by id desc");
while ($r = mysql_fetch_array($q)){
print "<input type='text' name='field[{$r[id]}]' value='$r[field]' />";
}
?>
<input type='submit' value='Save value' />
</form>
And then handle $_GET["field"] which is an array.
