Backend database Administrator

Hi Ray,

In the Dataassist Pages you have a user Admininstrator type but do you have any sort of backend database administrator type. I am looking for a way to update information in my venue table, I created a venue_update page but get:

Undefined index on line 7 $WADAvenue_update->bindParam("i", "".($_GET['venue_id']) ."", "-1"); //Paramvenue_id

I know from studying the forum that this indicates a missing url but I'm not sure how to put one in here. I did try duplicating the venue query page and setting the lint that was to go to venue profile to go instead to the update page, and the id does show in the address bar but the same problem still appears.So how do I create a backend database administration?

Thanks

I'm thinking $_GET['venue_id'] doesn't exist. I don't have a copy of your page, so I'm not really sure about the context.

For this code to work you would need a url like: pagename.php?venue_id=2

If you aren't linking into that page with a venue id then the error will occur.

venue_id is the key column in the venue table. So I'm guessing the venue_update page is asking for an input as to which venue I'd I'm looking to update. There are no users attached to this table or to the individual venues in the table. So I'm trying to figure out how to update the records.

For this code to work you would need a url like: pagename.php?venue_id=2

That identifies to the page what venue you want to update.

Yes but how do I get the venue_id= into the proper place on the update page to update the records in the venue table. Venue_id would normally be UserID from the user table as your update page was created to allow logged in users to update their own records. The venue table however does not have any associated users; none of the records in the venue table are linked to any user. In fact all of the records in the venue table are there through csv import. I cannot manually enter an id number every time I want to update a record, especially since once I hand this over I won't be the one doing it, so I have to automate the procedure somehow.

DataAssist to create a venue_update page for the venue table. Then I created venue query page venue_USAupdate and created a link for the Venue_Name column to the update page. So now when a Venue Name is clicked to takes you to the update page where the address bar does indeed show the id numbwer of the venue to be updated.

http://localhost/songwriters/venue_update.php?id=38

But somehow I need to get the id=38 to magically appear in the record set as the venue to be updated.Instead I get the message appearing above the table:
Notice: Undefined index: venue_id in C:\xampp\htdocs\songwriters\venue_update.php on line 7 and if I enter update information I then get:

Notice: Undefined index: venue_id in C:\xampp\htdocs\songwriters\venue_update.php on line 7
incorrect DOUBLE value:
Notice: Undefined index: venue_id in C:\xampp\htdocs\songwriters\venue_update.php on line 252

Is there a way to dynamically select the venue id and have it insert in the proper places to allow for a record update?

The url has ?id=38 instead of ?venue_id=38, so it doesn't match up with the code.

You can update the recordset to use id instead to make it match. Just update the line from:
$WADAvenue_update->bindParam("i", "".($_GET['venue_id']) ."", "-1"); //Paramvenue_id

to:
$WADAvenue_update->bindParam("i", "".($_GET['id']) ."", "-1"); //Paramvenue_id

If this is a user update and not for administrators, then you shouldn't be using a $_GET variable that can be easily manipulated. You should be saving the id in the session when they log in and using a $_SESSION reference on the page so it can only be changed by logging into the correct user account.

Thanks Ray, That's getting closer. Clicking on the venue name in the table now takes me to the update page with all the values filled in. However when I make a change anc click on update I get:

incorrect DOUBLE value:
Notice: Undefined index: venue_id in C:\xampp\htdocs\songwriters\venue_update.php on line 252
<input type="hidden" name="WADAUpdateRecordID" id="WADAUpdateRecordID" value="<?php echo((isset($_GET["invalid"])?ValidatedField("venue_update","WADAUpdateRecordID"):$_GET["venue_id"])); ?>" />

Just for fun I tried to change GET["venue_id"]) to GET["id"]) as in above and it changed the id to 0 but dod not make the other changes, specifically uploading an image.

Look at the url and that will tell you what the $_GET variable should be set to. Probably id since it would most likely match the other page.

Attach the page you are working on and I can try to see what else is wrong. The first error was probably fixed by your variable update and the other issue is somewhere else on the page so I'll need to have more information.

I did attach the page in #5 above. Thanks

On line 252 you still have:

<input type="hidden" name="WADAUpdateRecordID" id="WADAUpdateRecordID" value="<?php echo((isset($_GET["invalid"])?ValidatedField("venue_update","WADAUpdateRecordID"):$_GET["venue_id"])); ?>" />

Maybe search the whole page for $_GET["venue_id"] and update them all to $_GET["id"]
