search returns same result each time

Firstly - apologies for this being a real newbie question/problem: been banging my head against this for so long I can't see what's what. I have two pages - one lists a group of artists pulled from a MySQL db table. That bit works fine. What I'm trying to do is have these click through to the appropriate detail in the db, but what's happening each time is that the same record (the first in the table) gets returned. The first page is pre-test.php and the code is as follows:

-------------------------
<?php require_once('Connections/album.php'); ?><?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "")
{
$theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;

$theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);

switch ($theType) {
case "text":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
case "long":
case "int":
$theValue = ($theValue != "") ? intval($theValue) : "NULL";
break;
case "double":
$theValue = ($theValue != "") ? "'" . doubleval($theValue) . "'" : "NULL";
break;
case "date":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
case "defined":
$theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
break;
}
return $theValue;
}
}

mysql_select_db($database_album, $album);
$query_rsListing = "SELECT * FROM albumlist";
$rsListing = mysql_query($query_rsListing, $album) or die(mysql_error());
$row_rsListing = mysql_fetch_assoc($rsListing);
$totalRows_rsListing = mysql_num_rows($rsListing);
$query_rsListing = "SELECT artist FROM albumlist";
$rsListing = mysql_query($query_rsListing, $album) or die(mysql_error());
$row_rsListing = mysql_fetch_assoc($rsListing);
$totalRows_rsListing = mysql_num_rows($rsListing);
?><?php
// RepeatSelectionCounter_1 Initialization
$RepeatSelectionCounter_1 = 0;
$RepeatSelectionCounterBasedLooping_1 = false;
$RepeatSelectionCounter_1_Iterations = "4";

It's probably glaringly obvious to anyone what I'm doing wrong here but for the life of me I can't see it. Any assistance appreciated... thanks in advance.

Hiya Jeff,

I'm a complete novice as far as PHP goes, so nothing is glaringly obvious to me. The easiest thing to have done would have been to use the DataAssist wizard to create your results and detail pages, then place the code in context in your own pages.

But from what I can see, the problem with your link in pre-test.php is that it isn't passing any session data through to the second page (test.php), it is only using the artist variable to link to the page.

You can pass this on (apparently) as a session variable in the URL:

<a href="test.php?artist=<?php echo $row_rsListing['artist']; ?>"><?php echo($row_rsListing['artist']); ?></a>

and to prevent the URL from being mangled (according to php.net and DataAssist pages), encode (rawurlencode) the URL, so:

<a href="test.php?artist=<?php echo(rawurlencode($row_rsListing['artist'])); ?>" ><?php echo($row_rsListing['artist']); ?></a>

would be your whole link in pre-test.php.

From here on I'm just comparing your second page with one of my DataAssist detail pages, and it seems as if your test.php page is all there apart from:

php:

<?php

if (!session_id()) session_start(); 

?>

<?php

$Paramartist_rsAlbums = "-1";

if (isset($_GET['artist'])) {

  $Paramartist_rsAlbums = (get_magic_quotes_gpc()) ? $_GET['artist'] : addslashes($_GET['artist']);

}

$ParamSessionartist_rsAlbums = "-1";

if (isset($_SESSION['rs_Insert_listing'])) {

  $ParamSessionartist_rsAlbums = (get_magic_quotes_gpc()) ? $_SESSION['rs_Insert_listing'] : addslashes($_SESSION['rs_Insert_listing']);

}

$Paramartist2_rsAlbums = "-1";

if (isset($_GET['artist'])) {

  $Paramartist2_rsAlbums = (get_magic_quotes_gpc()) ? $_GET['artist'] : addslashes($_GET['artist']);

}

Which - if my tootling round php.net wasn't a totally wasted journey - means that firstly it's checking for a session id and then creating (resuming?) a session, and assigning the parameters for it according to the variable passed from the previous page. That's what I have struggled to make of it, but I may be talking rubbish. Hopefully someone will explain why. I have just transposed your info into it.

So your second page in its entirety would look (I think) pretty much like the page that I've attached. I'm entirely lazy about learning this stuff. I meant to get down to serious learning, but as DataAssist just does it all my motivation disappeared, and there's so much other cooler stuff to play with.

Some of the above might make some sense, and you can try it, but I wouldn't hold my breath. The bright young things will be in soon, and will help out.

Jeff,

on the test.php you have not set the rsAlbums recordset to have a filter.

In Dreamweaver, double click the rsAlbums recordset. In simple view set the filtering options to filter the artist column
Select URL variable from the filter type and type in artist for the variable name.

2/01/2010 3:23 pm | #5 Jason ByrnesWebAssist

Neilo,

Since your code was generated by the data assist wizard, the detail page was alredy set to filter the recordset.

In data assist pages, the detail page will loaded in three conditions:
1) from a link on the Results page

2) After Inserting a record.

3) After updating a record.

The Querystring variables are used when going from the results page.

The session variables are created to hold the id of the updated or inserted record to filter the correct record after insert or update.

In Jeff's case, he only needs to filter the record based on the query string variable since the results page he is creating will not be loaded after insert or update.
