beperking invoegen
Het is nogal een ingewikkelde sql...
dus.. de 3 eerste die ook in _content_fontpage (b.id_content) staan mogen NIET worden weergegeven

bv tabel met 21 id's, id 1-18 wordt weergeven...
Ook andere id's die NIET in die 2de tabel voorkomen mogen worden weergegeven.
een voorbeeld
TABEL 1
id onderwerp
1 ond1
2 ond2
" "
(tot bv 10)
TABEL 2
id_content
2
3
6
7
9
Dus dan krijg je een lijst waar id 9-7-6 niet bijstaan omdat dat de 3 hoogste id's zijn van tabel 2.
dus je ziet enkel:
10 - 8 - 5 - 4 - 3 - 2 - 1
Dat is eigenlijk de bedoeling en ik weet totaal niet hoe dit in zo'n sql te steken (of de php achteraf)...
Code (php)

SELECT id
FROM tabel1
WHERE NOT EXISTS
(
SELECT id
FROM tabel2
ORDER BY id DESC
LIMIT 3
)
FROM tabel1
WHERE NOT EXISTS
(
SELECT id
FROM tabel2
ORDER BY id DESC
LIMIT 3
)
. "\n WHERE NOT EXISTS(SELECT content_id FROM #__content_frontpage ORDER BY id DESC LIMIT 3)"
Staat er nu zo:
