parse error in nested query - please help.

[Polar]

I am having troubles finding the parse error in this script. I've been
checking for weeks. I am too new to the subject I guess.

I am trying to show a readord and them have a form at the bottom of the
page for inputting data to Update the record. I get a parse error that
points to the last line in the script so I know it is something I am missing
earlier in the script but doing a line by line it seems fine to me.

Thanks for any atempt and suggestions.

Polar :)

Count the number of "{" and compare with the number of "}".

I imagine they'll be different :)

Re: parse error in nested query - please help.

Thanks Pedro

I went over that many times - thinking the same thing - and low any beold on
my second to last bunch of hair I found it

Now I have a new problem. The query is not updating the record.

the $_Session['username'] is available as it is posting on top of the screen
about the form.
the Now() is evident it should be ok as is Accepted that leaves the
qualifier of the sud_id?

....

if (isset($_POST['accepted']) == 'Y') {
$query = "UPDATE Submission SET reader={$_SESSI ON['username']},
date_processed= NOW(), accepted='Y' WHERE sub_id=$row[0]";
echo "<b><p>Grea t A story to pass on!</p></b>";

....

is there an error here in my syntax That I am not seeing?

Thanks for the time and any comments

Polar :)

Not sure you can use isset() like that

http://uk.php.net/manual/en/function.isset.php

And where is $row[0] coming from?

Yes, in SQL syntax. I'll leave it up to you to find :)

You do not show your mysql_query() call and *most importantly* how
you're checking for errors!

I usually do (pseudo-code)

<?php
$query = "whatever";
$result = mysql_query($qu ery)
or die('Error in query [' . $query . ']. The error was: ' . mysql_error());
?>



Hint: is $_SESSION['username'] a string?

Okay I'll hazard a guess on this one. I haven't tested this particular
solution, but I've occasionally run into similar problems.

If Polar's $query is holding a string, is it possible that the php
expressions must be concatenated as they are in Pedro's example? For
instance, wouldn't you really need to do something like this:

$query = "UPDATE Submission SET reader='".{$_SE SSION['username']}."',
date_processed= NOW(), accepted='Y' WHERE sub_id='".$row[0]."'";

Also, wouldn't you want to do something like

/*temporary error check line*/
echo $query;

Just to make sure the query looks the way it's supposed to?

Hope this helps.

Re: parse error in nested query - please help.

I posted the full script ( I hope ) at the very beginning of the thread.

Thanks for the info and not just giving me the answer - I have only been
doing this for about 3 weeks now. So ALL this is new.

thanks again I'll let you know how my crawling goes...

I usually do that and then paste the result into phpmyadmin That
usually helps me find any SQL syntax errors.

No, not really. The string building of Polar's query is ok.
I don't like double quotes, but my die() expression could have been
written

die("Error in query [$query]. The error was: " . mysql_error());

That is also a good idea.
The idea behind the die is to get the query itself written to the output
as long as the reason for failure. Suppose you have this query

UPDATE xyz SET id=8 WHERE id=2

and try to run it on a database that has no xyz table. The die() output
will be something like

Error in query [UPDATE xyz SET id=8 WHERE id=2]. The error
was: Table 'xyz' doesn't exist
