Question

If i do a mysql-select within the ts-setup and call the result of this select in, lets say, three extensions placed on the same site, does that still mean, that this certain mysql-select is done exactly once within each call of the site?

If so, it would be smarter to do the mysql-select in the typoscript and give the result to the extensions, so i dont have to do the same mysql-select over and over for each extension again, right?

Or is the text from the typoscript handled another way?

Thanx in advance,

If that are exactly the same request, it will hopefully cached by mysql-query-cache. But, you are right, the request will be send three times.

If i understand you right, you think about doing sth. like:

lib.mySqlSelect = CONTENT
lib.mySqlSelect ...
plugin.tx_yourplugin.select.cObject < lib.mySqlSelect

That would result in three SQL Querys too.

But you could use an LOAD_REGISTER:

plugin.tx_yourplugin.select = {register:mySqlSelect}
plugin.tx_yourplugin.select.insertData = 1

page.1 = LOAD_REGISTER
page.1.mySqlSelect = CONTENT
page.1.mySqlSelect ...

Assuming “select” has stdWrap property.

If you are writing a new extension, you could use $GLOBALS['TSFE']->register[$register] = $theValue;
