RE: [PHP-DB] undefined index
Hi!
Drop the quotes around your array keys. It should be $row[imageurl] for
example.

Subject: [PHP-DB] undefined index
hi to all
I try to get data listed out of my database with the statement
...
while ($row = mysql_fetch_array($sql)) {
$image = $row["imageurl"];
$id = $row["productID"];
$name = $row["cdescription"];
...
If i havent got anything in that field in my database I get the error
message in my browser
Undefined index: imageurl in ...
How can I overcome that problem? Is there a way to define a index if that
occurs and make it to not produce that error message?
Hope I have explained it understandable enough. If you need to know more
details let me know, I would appreciate any help I could get. Thanx
P.

Re: [PHP-DB] undefined index
I don't think dropping the quotes is the best solution.
One might consider dropping the warning level in php.ini, if it is a
problem, or use numbered array like mysql_fetch_row() returns.

Re: [PHP-DB] undefined index
Your best bet is to do some isset() calls:
eg
if(isset($row['imageurl']))
{
$image=$row['imageurl'];
}
else
{
/*maybe report the problems or handle it like this...*/
$image=$default_image_url;
/*where you have already set up $default_image_url to point somewhere
sensible*/
}
Cheers

RE: [PHP-DB] Undefined index and variables
It does not appear that you have posted the code from the add.php page in
your original post (below). From the error messages you provided, that seems
to be where the error is happening. You'll need to post the add.php code and
identify line #23 for us to be able to help.

RE: [PHP-DB] Undefined Index error when trying to insert data from a form into a db
Chris,
It appears that the indices called out in the lines of error code are not
being transferred from the Insert_Table_Form.html page and that is causing
the query to ultimately fail. Almost self-explanatory due to PHP's good
error reporting.
First make certain that the names of the form controls on the
INsert_Table_Form.html page match up exactly with the names in your code on
lines 9 through 21.
Secondly, make sure each of the controls has a value when you attempt to
post the data from Insert_Table_Form.html. Some form controls will not
appear in the $_POST['indices'] array if they do not contain a value and
when you try to reference those empty controls, they cause problems because
they were never posted.
Hope this helps.
Rich

Re: [PHP-DB] Undefined Index error when trying to insert data from a form into a db
1. Check the manual on use of $_POST and notch down your error reporting level. As these vars have not been defined PHP is throwing an error. 2. While you are at it, and assuming that your variables are all received correctly, why not simplify your sql? insert into test_scores set field_one = '$field_one', field_two = ''$field_two ... and so forth. It makes debugging INFINITELY easier and gives you more control. 3. Not related to your question at all, what's the type of your first field? Does it allow NULL's? If so then default it to NULL. (Something tugging at the back of my mind says that a NULL should not be assignable, but that's another issue.)
