Slette spørgsmål og svar fra forumDB
Jeg har et forum, hvor det skal være muligt at slette data. De hænger sammem med et ID til spørgsmålet og et REPLYID til svaret. Jeg kan godt få slettet spørgsmålet (ID) men ikke svaret (REPLYID) Spørgsmålet er så hvordan kan jeg slette begge dele i et hug.
Tabellen ser således ud.
id ForumId name email subject comment date replies orgthread replyid
Spørgsmålet får et id =10 og replyidid =0 Første svar får et id=11 og replyid=10 Andet svar på det samme får et id=11 og replyid=10
I dette særtema ser vi på, hvordan cloud og AI bliver fundamentet for virksomhedernes digitale forretning, og hvordan de nye muligheder for automatisering og forretningsværdi kan udnyttes uden at miste overblik, sikkerhed og menneskelig kontrol.
Det skulle være nok med id=2376 og så den SQL som jeg har vist. For den slette hvor ID = 2376 og det er så "Hoved tråden". Den sletter også de records hvor replyID = 2376 og det er det er kun de svar der høre til ID = 2376 som har replyID = 2376.
Ja det er rigtigt men jeg har slettet det spørgsmål med id=2376 og alligevel kan man se det tomme spørgsmål (ingen txt) med alle svarene under sig, den kommer godt nok op med en fejlmeddelse. Du kan se det her. http://www.ct-lund.dk/forum/viewmsg.asp?id=2322&ForumID=5
2376 er en test 2322 er et rigtigt spørgsmål der er slettet. Der mangler "bare" at man sletter svarene på samme tid som spørgsmålet. Ideen er at de selv kan gå ind og slette. Ellers skal der laves en extra side hvor man sletter svarene. Så er det at bliver for besværligt.
De er slettet med en form Code her. Der er en masse xtra code men det er jo dreamweaver mx. Den får input fra denne side

ja det er den MM_editConnection = MM_Forum_STRING MM_editTable = "Entries" MM_editColumn = "id" MM_recordId = "" + Request.Form("MM_recordId") + "" MM_editRedirectUrl = "main.asp" kan man smide noget extra ind der som sletter replyid også
Nu kender jeg ikke lige DreamWeaver men det liger nogle variable som den opretter ud fra noget du kan skrivet et sted eller så tilføj dette til listen :
Det gik ikke Jeg ændrede det og den står stadig og kører måske et loop.
Kan det ikke være denne kode der sletter.
<form name="form1" method="POST" action="<%=MM_editAction%>"> Slet dette indlæg. <input type="submit" name="Submit" value="SLET"> <input type="hidden" name="MM_delete" value="form1"> <input type="hidden" name="MM_recordId" value="<%= forumpost.Fields.Item("id").Value %>"> </form> Den sender id til db med besked om at slette.
Nu virker det. Skulle lige opdatere browser vindue.
Du styrer for vildt.
