i am trying to make a simple database template(?). adding and deleting from the mysql database worked fine untill I tried to add edit, the edit wont work. also it always says 'Record has been deleted from database', its only supposed to say that when you delete from it. I also tried to use a switch to control everything but nothing worked after that. can someone look at my code and tell me whats wrong? (my webhost doesnt support php so its just a text file.)

Well I'll be...
Did as you suggested. It fixed that error, took me down another 10 or so lines to a few others, which were probably stray tabs that I put in thinking it wouldn't affect it.
Then I got a few more on the other pages that I took care off, now they are ok - but I cannot add a record. I don't get an error after I submit, I get nothing.
I'll need to take another look....

If I close the bracket before the series of echo stmnt, that fixes that error , but it just gives me another on the stray

Does the db_table variable contain what you think it does? Try echoing the query to see if it's correct. //Daniel

DiamondLil,
I have found that staying in PHP mode and using print or echo statements for output makes debugging PHP a lot easier.

Try echo'ing your variables. Does db_table, db_host, db_name, db_user and db_pass have the correct values? //Daniel

Hi,
That's how I had it before (see 7 posts, 8 from this one, ago). Yes, I just double-checked and all the variables are correct.

ok - now, no error, but i'm not adding records. Can add records through telnet/mysql, though.

You do know that your file only selects and output records, right? It has no insertion anywhere. //Daniel

Yes, this page. But I do have an add.php that theoretically is supposed to be adding records.

aargg. help. please.
(this is even harder because I'm supposed to be working on two completely different projects, preventing me from concentrating on one of them until it's done...)
The link:
The code is the same as in last post, because even though I have gone through each of the pages, I'm not finding any stray characters. I've deleted and re-typed certain pieces.
I can add records so I know that I'm connecting & that the variables are ok, but when I click on "edit" on index.php, it does not grab the values of the cells and plug them into the form fields for the edit.php pg.
When I hit "edit", I'm getting : Warning: Supplied argument is not a valid MySQL result resource in /usr/local/etc/httpd/htdocs/prologi/editbox/edit.php on line 5.
Here are the first 6 lines of edit.php:
<?
mysql_connect($db_host, $db_user, $db_pass);
mysql_select_db($db_name);
$result = mysql_query("SELECT * FROM $db_table WHERE id=$editid"
$edit = mysql_fetch_array($result);
?>
Also, the "delete" link isn't working. It looks like it is reading delete.php and refreshing the index.php pg, but it's not deleting the info. It's not giving me an error message.
I'm editing the pages in SimpleText so I know that it's not a GoLive wysiwyg messing with the code thing.
Any ideas?

That usually indicates that you have a missing } or something similar. Have you tried putting ;'s after all your echo's (<?=$variable?> works the same way and is better IMO). //Daniel

hi daniel.
So you are saying that :
<input type="text" name="loaddate" value="<? echo $edit["loaddate"] ?>">
should be:
<input type="text" name="loaddate" value="<? echo $edit["loaddate"]; ?>">
