phpbb3.2 to SMF 2.0.15

[numand]

Hi,

I am trying to convert a phpbb3.2 forum to a SMF 1.0.15 forum. When I run the convert script[1], it prints this error:

/usr/bin/php7.0 -f convert.php -- --path_to=/var/www/smf --path_from=/var/www/phpbb --db_pass=nnn --convert_script=phpbb3_to_smf.sql

Mentioned error lien (2721, 2725 and 2726) are in this function:

function convert_fetch_assoc($result)
{
global $smcFunc;

// Okay, the hardest is ADO (Windows only, by the way.)
if (!is_resource($result) && is_object($result))
{
if ($result->EOF) //-------> 2721
return false;

$row = array();
$fields = $result->Fields; //----------> 2725
for ($i = 0, $n = $fields->Count; $i < $n; $i++) //---------> 2726
{
$field = $fields[$i];
$row[$field->Name] = $field->Value;
}
$result->MoveNext(); //-------------> 2731

return $row;
}

$type = get_resource_type($result);
if ($type == 'odbc result')
return odbc_fetch_array($result);
else
return $smcFunc['db_fetch_assoc']($result);
}


But

$result->MoveNext(); statement is not only in this function but in lots of functions.

Could you help me to solve this problem?

Try to conver to SMF 1.0.13.

[numand]

@digger,

Are you suggesting that first install SMF 1.0.13 and then run convert script?

[digger]

@digger,

Are you suggesting that first install SMF 1.0.13 and then run convert script?

Yes

[Illori]

SMF 1.0 or SMF 1.1.* does not support php 7.* you might not have a lot of luck getting it to work.

[digger]

@digger,

Are you suggesting that first install SMF 1.0.13 and then run convert script?

I mean 2.0.13. Sorry.

Thank you for advise @digger but I got the same error. This is from SMF 2.0.13:

Did you try to downgrade php version?
Some time ago I converted old phpBB forum and encountered the same error, but successfully converted to SMF 2.0.13 with php 5.4 finally.

[numand]

@digger,

No, I did not try to downgrade PHP version to 5.4. According to this[1] answer, the minimum version of PHP that can be installed is 5.6. I will try this in my local computer in order to not to mess server.

You can try with php 5.6. I think this converter needs php version with old mysql extension support and smf version without php 7.0 support.

[numand]

@digger,

As you said, PHP 5.6 with old MySQL/MariaDB extension partially works. Even so the converter did not do its job completely.

This is what I did so far:
1. Comment out functions that contains SQL_MAX_JOIN_SIZE in convert.php

2. Remove some parameters(?) form phpbb3_to_smf.sql file

u.user_{msnm, aim, icq, yim, website}, u.user_from is not important but hxxp:f.forum [nonactive]_posts and hxxp:f.forum [nonactive]_topics are important datas. These are errors I get if I do not change phpbb3_to_smf.sql file:

OK, I changed phpbb3_to_smf.sql file according to this[1] post but instead of changing t.topic_replies to t.topic_posts, I changed to t.topic_posts_approved. And converting phpbb3 to SMF ended successfully!

Thank you for your guidance @digger!

For some reason I cannot get this running with PHP5.6.
Error is the same as in the first post.

Did you use the attached files from this post?

Hello, while converting from phpBB3.2 -> SMF 2.0.19 I noticed that the topics have lots of html in their content:

Code Select Expand

<B><s>[b]</s><I><s>[i]</s><U><s>[u]</s>Biografia:<e>[/u]</e></U><e>[/i]</e></I><e>[/b]</e></B><br/>

Is this an artefact caused by conversion, or should I be able to get around this?

[vbgamer45]

It's a known issue at this point. Still working on a fix.

[CrimeS]

Thanks, I thought so!

[vbgamer45]

Yeah, I tried last night using SMF's built in function to convert html to bcc haven't got it to work yet. Needs tweaks to get it to work with the convertor might be a slow process

[Massl]

I tried to convert phpbb to mybb, because the mybb to smf converter works well, but mybb converter also doesn't work.

Still working on a fix.

Thanks
