Joomfish migration script returns error - php

Question

Here is a script that upgrades joomfish (joomla translation component) from joomla 1.5 to 2.5:
$db = new PDO("mysql:host=localhost;dbname=db;charset=UTF8", "root", "pass");
$stmt = $db->prepare("select distinct(jfc.reference_id),c.catid,jfc.language_id,c.modified,c.modified_by,c.version,c.modified_by ,c.ordering,c.created_by,c.metadesc ,c.created_by_alias from jos_jf_content jfc ,jos_content c where jfc.reference_id = c.id and jfc.reference_table = 'content' ");
$stmt->execute();
$results = $stmt->fetchAll(PDO::FETCH_ASSOC);
foreach($results as $row) {
$count_row = $db->prepare("select * from jos_jf_content where reference_id = ? and language_id = ?");
$count_row->bindValue(1, $row['reference_id']);
$count_row->bindValue(2, $row['language_id']);
$lang_code = $db->prepare("select lang_code from j25_languages where lang_id = ?");
$lang_code->bindValue(1, $row['language_id']);
$lang_code->execute();
$l_code = $lang_code->fetch(PDO::FETCH_OBJ);
$language_code = $l_code->lang_code;
$count_row->execute();
$title ="";
$fulltext ="";
$introtext ="";
$alias ="";
$published ="";
while($col = $count_row->fetch(PDO :: FETCH_ASSOC))
{
if($col['reference_field'] == "title")
{
$title = $col['value'];
}
if($col['reference_field'] == "fulltext")
{
$fulltext = $col['value'];
}
if($col['reference_field'] == "introtext")
{
$introtext = $col['value'];
}
if($col['reference_field'] == "alias")
{
$alias = $col['value'];
}
$published = $col['published'];
}
$exe = $db->prepare("insert into j25_content (`title`,`alias`,`introtext`,`fulltext`,`published`,`catid`,`created`,`created_by`,`created_by_alias`,`modified`,`modified_by`,`version`,`ordering`,`metadesc`,`language`) values(:title,:alias,:introtext,:fulltext,:published,:categoryid,:created,:created_by,:created_by_alias,:modified,:modified_by,:version,:ordering,:metadesc,:language_code)");
$exe->execute(array(':title' => $title,':alias' => $alias,':introtext' => addslashes($introtext),':fulltext' => addslashes($fulltext),':published' => ".$published.",':categoryid' => $row['catid'],':created' => date("Y-m-d H:i:s"),':created_by' => $row['created_by'],':created_by_alias' => "".$row['created_by_alias']."",':modified' => date("Y-m-d H:i:s"),':modified_by' =>$row['modified_by'],':version' => $row['version'],':ordering' => $row['ordering'],':metadesc' => $row['metadesc'],':language_code' => $language_code));
$i = $db->lastInsertId('id');
$asst = $db->prepare("select asset_id from j25_categories where id = ? ");
$asst->bindValue(1, $row['catid']);
$asst->execute();
$asst_id = $asst->fetch(PDO::FETCH_OBJ);
$cassetid = $asst_id->asset_id;
$sel = $db->prepare("select lft,rgt FROM `j25_assets` where id = (SELECT max(id) FROM `j25_assets`)");
$sel->execute();
$select = $sel->fetch(PDO::FETCH_OBJ);
$left = $select->lft;
$right = $select->rgt;
$left=$left+1;
$right = $right+1;
$stmt = $db->prepare("insert into j25_assets (`parent_id`,`lft`,`rgt`,`level`,`name`,`title`) values(:cassetid,:left,:right,:level,:name,:title)");
$stmt->execute(array(':cassetid' => $cassetid,':left' => $left,':right' => $right,':level' => 4,':name' => "com_content.article.".$i,':title' => $title));
$insertedId = $db->lastInsertId('id');
$update = $db->prepare("update j25_content set asset_id = ? where id = ?");
$update->bindValue(1, $insertedId);
$update->bindValue(2, $i);
$update->execute();
$stmt = $db->prepare("insert into j25_jf_translationmap (language,reference_id,translation_id,reference_table) values (:language_code,:reference_id,:translation_id,:content)");
$stmt->execute(array(':language_code' => $language_code,':reference_id' => $row['reference_id'],':translation_id' => $i,':content' => 'content'));
}
Line of code:
$language_code = $l_code->lang_code;
Returns:
Trying to get property of non-object
I'm not an author of the script and not good in PHP, but I've tried to print_r($l_code->lang_code); and I got expected result en-GB from [lang_code] => en-GB. What I need to change in this code? Thanks.

Answer 1

The line $language_code = $l_code->lang_code > 0; sets $language_code to boolean value. Try var_dump($l_code); and var_dump($language_code); to debug your results. You should also check if $l_code actually is an object, or perhaps null was returned. Hope that helps.
