PHP Help
Hey guys...I'm getting better! (lol)
Ok, here's the deal...i'm connecting to a dB and printing information into a page (.php). It doesn't print the data from the dB. Here's the code:
<?php
echo \"xml version=\\"1.0\\" encoding=\\"UTF-8\\"\n\";
...connection...
$qry = mysql_query(\"SELECT * FROM news WHERE data='$data' AND date='$date'\");
$text = $qry[text];
$date = $qry[date];
echo \"xml version=\\"1.0\\" encoding=\\"UTF-8\\"\n\";
?>and then in the page i have:
<p><?=$date?>:<br /> <?=$text?></p>
<?php
mysql_close($dbh);
?>what's wrong? i have data in the dB, correct fields and everything! thanks for the help!

your missing the fetch data bit
something like:
$row = mysql_fetch_array($qry);
and then $row[text] etc
why do you have two xml tags? and you should also have an if statement incase of error
$qry = mysql_query("SELECT * FROM news WHERE data='$data' AND date='$date'");
if(!$qry) {
echo ("error performing task: ". mysql_error() . "");
} else {
$row = mysql_fetch_array($qry);
...
the mysql_error is handy for trouble shooting

Try
<?php
echo \"xml version=\\"1.0\\" encoding=\\"UTF-8\\"\n\";
... connection ...
$qry = mysql_query(\"SELECT * FROM `news` WHERE data='$data' AND date='$date'\");
$rslt = mysql_fetch_array($qry);
$text = $rslt['text'];
$date = $rslt['date'];
?>
Also, how come you have the same echo statement twice for the XML?

it's telling me that mysql_fetch_array isn't a valid "result resource", and i checked php.net, it looks good to me....?!
i was told that you should send the xml header twice, or it will confuse the browser, and possibly screw up your presentation, but speaking of which, i just re-ran it, it had an error, got rid of the last declaration, and it works fine now. lol.

Try this code:
<?php
$con = mysql_connect('locahost','user','pass') or die(mysql_error());
mysql_select_db('db',$con) or die(mysql_error());
if ((!isset($data))||(!isset($date))) {
echo 'Error Returned: Proper variables not set.';
} else {
$query = mysql_query(\"SELECT * FROM `news` WHERE data='$data' AND date='$date'\") or die(mysql_error());
$result = mysql_fetch_array($query) or die(mysql_error());
$text = $result['text'];
$date = $result['date'];
}
?>

As I'm sure you suspected, it returned "Error Returned: Proper variables not set".
What does this mean? i have set the proper variables in both the dB and the php!

How are you obtaining the variabls $data and $date? From the URL? If yes, try $_GET['data'] and $_GET['date']

the variables will be submitted via form, although I have been inserting them directly into the table

If they are submitted via form and its a POST form then you need to use $_POST['var'].

Yes even in a dB, where ever you need to use the variables. Where else does "it" know where to get it from?

$text = $_POST['text'];
dollar sign infront of the variable name, and single quotes inside the boxed brackets, not outside.
Just remember the method in the form MUST be post to use $_POST, if it's get, use $_GET
