help with sql update script

Symbiot · October 27, 2014

Hi

i've got a script to migrate some tables.

This is most of it.. just missing the db connection (not needed here)


$link = mysql_connect($host,$user,$pass) or die(mysql_error());
mysql_selectdb($db,$link) or die(mysql_error());
$ag_forums_to_kunena_categories = array();

mysql_query("TRUNCATE bzhv8_kunena_messages");
mysql_query("TRUNCATE bzhv8_kunena_messages_text");
$sql = "
SELECT
 p.id AS messages_id, 
 u.name AS messages_name, 
 a.jos_id AS messages_userid, 
 p.message AS messages_text_message,
 p.posted AS messages_time,
 p.edited AS messages_modified_time,
 p.edited_by AS messages_modified_by,
 p.topic_id AS messages_thread,
 t.forum_id AS messages_catid
 
FROM jos_agora_posts AS p
LEFT JOIN jos_agora_users AS a ON a.username = p.poster
LEFT JOIN jos_agora_topics AS t ON t.id = p.topic_id
LEFT JOIN bzhv8_users AS u ON u.id = a.jos_id
 
ORDER BY p.id ASC
";
 
$res = mysql_query($sql) or die(mysql_error());
while ($row = mysql_fetch_object($res))
{
	echo $row->messages_id;
	//echo "<br />";
	//echo $row->messages_name;
	//echo "<br />";
	//echo $row->messages_userid;
	//echo "<br />";
	//echo $row->messages_text_message;
	//echo "<br />";
	//echo $row->messages_time;
	//echo "<br />";
	//echo $row->messages_modified_time;
	//echo "<br />";
	//echo $row->messages_modified_by;
	//echo "<br />";
	//echo $row->messages_thread;
	//echo "<br />";
	//echo $row->messages_catid;
	//echo "<br />";
	
	//if($row->messages_userid == '')
	//echo "userid er nul";
	//{
	//	$row->messages_userid = 0;
	//}
 
	$cat_id = $ag_forums_to_kunena_categories[$row->messages_catid];
	
	if ($cat_id != 0)
	{
		echo $cat_id;
		echo "kategori id";
		echo "<br />";
		echo "lige før den skal indsætte";
		$sql = "INSERT INTO `bzhv8_kunena_messages` VALUES (".$row->messages_id.", 0, ".$row->messages_thread.", ".$cat_id.", '".$row->messages_name."', ".$row->messages_userid.", '', '', ".$row->messages_time.", NULL, 0, 0, 0, 0, 0, 0, 0, 0, '')";
		echo "her bør den køre sql(1)";
		$sql2 = "INSERT INTO `bzhv8_kunena_messages_text` VALUES (".$row->messages_id.", '".mysql_escape_string($row->messages_text_message)."')";
		echo $sql;
		echo "lige efter anden insert echo sql";
		echo "<br />";
		echo $sql2;
		echo "<br />";
		echo "her skulle den vise anden insert";
		mysql_query($sql) or die(mysql_error());
		mysql_query($sql2) or die(mysql_error());
	}
	else
	{
	
	
    }
}
mysql_close();

But something is not working..

first.. ignore the echo's of course.. just me trying to debug.. same with the else statement...

from what I can tell.. and my php knowledge is non-existant.. this part:

$cat_id = $ag_forums_to_kunena_categories[$row->messages_catid];

it what's causing the problem.. it appears that the $cat_id is not getting any data..

if copy the sql line and run it against my database via phpmyadmin then it works as it should.. but well.. something isn't right..

there are some other stuff in the script that does the same as the above.. but with different tables and they work just fine..

example:

mysql_query("TRUNCATE bzhv8_kunena_topics");
$sql = "
SELECT
 t.id AS topic_id,
 t.poster AS topic_poster,
 t.subject AS topic_subject, 
 t.posted AS topic_first_post_time, 
 t.last_post AS topic_last_post_time, 
 t.last_post_id AS topic_last_post_id, 
 t.last_poster AS topic_last_poster, 
 t.num_views AS topic_hits, 
 t.num_replies AS topic_posts, 
 t.closed AS topic_locked, 
 t.sticky AS topic_hold, 
 t.moved_to AS topic_moved_id, 
 t.forum_id AS topic_category_id, 
 t.question AS topic_poll_id,
 p.id AS topic_first_post_id, 
 p.posted AS topic_first_post_time, 
 a.jos_id AS topic_first_post_userid,
 p.message AS topic_first_post_message
 
FROM jos_agora_topics AS t
LEFT JOIN jos_agora_users AS a ON a.username = t.poster
LEFT JOIN jos_agora_posts AS p ON t.posted = p.posted
ORDER BY t.id ASC
";
 
$res = mysql_query($sql) or die(mysql_error());
while ($row = mysql_fetch_object($res))
{
	echo $row->topic_id;
	echo "<br />";
	if($row->topic_first_post_userid == '')
	{
		$row->topic_first_post_userid = 0;
	}
 
	$cat_id = $ag_forums_to_kunena_categories[$row->topic_category_id];
	echo $cat_id;
	echo "<br />";
	$sql = "INSERT INTO `bzhv8_kunena_topics` VALUES (".$row->topic_id.", ".$cat_id.", '".mysql_escape_string($row->topic_subject)."', 0, ".$row->topic_locked.", ".$row->topic_hold.", 0, ".$row->topic_posts.", ".$row->topic_hits.", 0, 0, 0, ".$row->topic_first_post_id.", ".$row->topic_first_post_time.", ".$row->topic_first_post_userid.", '".mysql_escape_string($row->topic_first_post_message)."', NULL, ".$row->topic_last_post_id.", ".$row->topic_last_post_time.", 0, NULL, NULL, '')";
	echo $sql;
	echo "<br />";
	mysql_query($sql) or die(mysql_error());
}

the above works fine..

Can someone take a look and give a hint or 2.. or just point at whatever the solution is :-)

$ag_forums_to_kunena_categories = array();

$cat_id = $ag_forums_to_kunena_categories[$row->messages_catid];

$ag_forums_to_kunena_categories is an empty array. I don't see you put anything into it in that code.

turn on error checking - it will tell you that MySQL_selectdb is invalid.

mac_gyver · October 27, 2014

it's a deprecated alias -

Note:
For backward compatibility, the following deprecated alias may be used: mysql_selectdb()

ginerjm · October 27, 2014

a deprecated alias of a deprecated function. Go figure....

hi guys

thanks for responding... I will have to look into the "depreated" part.. but I am not sure what to do..

just to show you the full script and see if it makes mores sense..

$ag_forums_to_kunena_categories = array();
$cat_id = $ag_forums_to_kunena_categories[$row->messages_catid];
$ag_forums_to_kunena_categories is an empty array. I don't see you put anything into it in that code.

.. you mention not putting in any data...

Can you spot why the rest of the script seems to be working then?
