Description

I have createt an extension. When I write the following in the tca.php File I get the an error:
"config" => Array (
"type" => "select",
"foreign_table" => "xxx",
"foreign_table_where" => "AND xxx.sys_language_uid = ###REC_FIELD_sys_language_uid### ORDER BY xxx.name",
"maxitems" => 100,
....
)

I get this error if I create a record of this type:
Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource in xxx/htdocs/typo3_src-4.0/t3lib/class.t3lib_db.php on line 801

The error comes only if "###REC_FIELD_sys_language_uid### " is in the "foreign_table_where" AND "maxitems" is higher then 1.
If I set "maxitems" = 1 or I delete the part "AND xxx.sys_language_uid = ###REC_FIELD_sys_language_uid###" the error does not come.

(sorry if my english is not so good.... ;-) )

Sorry I've forgot something.
This error only comes if I create a new record. If I press the save Button or edit an existing record then comes no error.
Maybe the "###REC_FIELD_sys_language_uid###" marker is not set correctly if
- the record is not saved
- maxitems is 1

Hi,

i found a workaround - I use this expression:
CAST

So if the marker is empty it will be converted to 0

Hi Steffen,

your workaround sounds good.

Is the cast expression standard sql?

A while ago I created a patch for the 4.1 branch.
Maybe the patch is of help.

I have added patches for trunk (4.3), 4.2 and 4.1 which correct the odd situation.

As mentioned in my note from 2008-04-30 this can easily be fixed with the patches attached.

This odd situation does only appear if you use a ###REC_FIELD_*### marker inside the foreign_table_where configuration.

$TCA['tx_faqs']['columns']['similar_faq']['config']['foreign_table_where'] = ' AND tx_faqs.deleted=0 AND tx_faqs.pid IN (103) AND tx_faqs.sys_language_uid=###REC_FIELD_sys_language_uid### ORDER BY tx_faqs.question ASC'

The example above would only list other records if they have the same sys_language_uid which keeps the list smaller if you have more than 2 languages on your TYPO3 installation.
