Split(?) & Flood Control @ tutorials.de: Tutorials, Forum & Hilfe

schutzgeist · 06.05.05 13:19

Ich bastel gerade an meinem Gästebuch und suche dafür noch 2 Scripts, da ich bisher leider nicht selbst auf die Lösung gekommen bin.

Zum einen möchte ich bei der Textausgabe, dass mit Wörter/Zeichenketten die länger als 20 Zeichen sind mit einer Leerstelle getrennt werden (zwecks Layout auseinander ziehen).
Ist bestimmt total einfach

Hab mich bei google halbtot gesucht, nichts passendes, oder nur Beispiele für php gefunden

Zum anderen such ich was, das mir nachdem ein Beitrag abgeschickt wurde der Absender erst 5min warten muss, bevor er einen neuen Beitrag verfassen kann und der Submit-Button über/ausgeblendet wird.
Ich schätz mal, das ganze muss irgendwie über nen Cookie oder so laufen. Wovon ich aber leider absolut keine Ahnung hab

Danke schonmal fürs Lesen,
schutzgeist

Zur 1. Frage

Ein Wort mit 20 Zeichen kommt ja selten vor. U.u. handelt es sich hier um eine längere URL oder jemand macht dies, um Dich zu ärgern oder jemand möchte Dir einen Code unterschieben. Wenn ein solches Wort vorkommt, lass den Eintrag nicht zu, sondern setz eine Meldung, dass er das Wort trennen soll.

Du solltest die Ausgabe des Gästbuchtextes auch encodieren. z.B. mit

dim Eintrag
eintrag = rs("eintrag")
Response.write Server.HTMLEncode(eintrag)

http://www.tutorials.de/tutorials194841.html

Zur 2. Frage

Direkt nach Einfügen des Datensatzes erzeugst du einen Cookie und setzst die Lebensdauer auf 5 min.

Response.Cookies("update") = true
Response.Cookies("update").Expires = dateAdd("n",5, now())

Dann fragest Du den Cookie ab, ob er gefüllt ist und erzeugst eine Variable, die den Button disabled setzt.

dim nextDisabled
nextDisabled = ""
if Request.Cookies("update") = true then nextDisabled = "disabled"

<input <%=nextDisabled%> type="submit" name="submit" value="eintrag"/>

Weitere Infos zum Thema Cookie auch hier.

Ich versteh nicht ganz, wo ich beiden Sachen genau einbauen muss...

Luzie · 06.05.05 16:01

Hi

hier mal ein Testformular, kannst Dir mal in eine leer Seite speichern und ausprobieren.

Code :

<%@LANGUAGE="VBSCRIPT" CODEPAGE="1252"%>
<%
option explicit
' -- Abfrage, ob Submit-Button dargestellt wird
 
dim nextDisabled
nextDisabled = ""
if Request.Cookies("update") = "1" then nextDisabled = "disabled"
 
' --- Funktion überprüft das Eingabefeld, ob ein Wort länger als 20 Zeichen existiert
' --- Liefert als Werteausgabe true zurück.
 
function Langwort(b)
dim a,x
a = split(b," ")
    for i = 0 to ubound(a)
        if len(a(i)) > 20 then
            x = true
        end if
    next
Langwort = x
end function
%>
<html>
<head>
<title>fdasdfasdf</title> 
<meta http-equiv="Content-Type" content="text/html;">
</head>
<body>
<%
dim allesok, message, spltext, Fehler, i
 
' --- Feldüberprüfung
 
if Request.Form.count > 0 then
allesok = true
message = Replace(Request.form("message"),"'","''")
    if langwort(message) then
        allesok = false
        Fehler = "zu langes Wort"
    end if
 
    if isnull(message) or message="" then
        allesok = false
        Fehler = "Bitte einen Eintrag machen"
    end if
end if
if allesok then
' --- hier an dieser Stelle kann das Script zum Eintrag in die Datenbank rein
' --- hier wird der Cookie mit Lebensdauer 5 Min. gesetzt.
Response.Cookies("update") = 1
Response.Cookies("update").Expires = dateAdd("n",5, now()) 
Response.redirect Request.ServerVariables("Script_name") 
end if
%>
Der Cookie hat den Wert: <% = Request.Cookies("update") %>
<form name="form1" method="post" action="<% =Request.ServerVariables("Script_name")%>">
  <h1>Eintrag machen  </h1>
       <textarea name="message" id="message"><% = message %></textarea>
    <% = Fehler%>
    <br>
    <br>
    <input <%= nextDisabled %> type="submit" name="submit" value="eintrag"/>
 
</form>
</body>
</html>

Heho

Das mit dem Zeichen trennen hab ich jetzt andersweitig gelöst bekommen...
Aber an dem Floodding beiß ich mir momentan noch die Zähne aus...
Egal wie ich es reinschreib, umstell, etc. er mecker immer das Option Explicit an und bringt mir ne Meldung von wegen Kompilierungsfehler

Fehlertyp:
Kompilierungsfehler in Microsoft VBScript (0x800A0400)
Anweisung erwartet

Luzie · 09.05.05 10:45

Hi

option explicit muss immer in der 1. Zeile nach der Sprachangabe stehen, wenn Du es einbauen willst. Es ist optional und prüft, ob alle Variablen benannt sind.

Ansonsten kann ich nur sagen, dass ich nicht Hellsehen kann.
Musst schon Deinen Scriptcode hier posten.

Hi

achso, ist Dreamweaver-Scriptcode.
Nimm, bis auf dies, mal alles im 1. Teil oben heraus.

Code :

<%@LANGUAGE="VBSCRIPT" CODEPAGE="1252"%>
<!--#include file="Connections/gb.asp" -->
<%
dim nextDisabled
nextDisabled = ""
if Request.Cookies("update") = "1" then nextDisabled = "disabled"
end if
%>
 
<%
' *** Edit Operations: declare variables
 
Dim MM_editAction
Dim MM_abortEdit
Dim MM_editQuery
Dim MM_editCmd
[...]

Den Cookieteil musst erst, nachdem die Eingabe getätigt worden ist, schreiben, das ist ja logisch, oder ?

Code :

 If (Not MM_abortEdit) Then
    ' execute the insert
    Set MM_editCmd = Server.CreateObject("ADODB.Command")
    MM_editCmd.ActiveConnection = MM_editConnection
    MM_editCmd.CommandText = MM_editQuery
    MM_editCmd.Execute
    MM_editCmd.ActiveConnection.Close
    Response.Cookies("update") = 1
    Response.Cookies("update").Expires = dateAdd("n",5, now()) 
    If (MM_editRedirectUrl <> "") Then
        Response.Redirect(MM_editRedirectUrl)
    End If
  End If

Aber wie gesagt, dies ist ein Eingriff in das gen. Verhalten. Wenn Änderungen zu machen sind, dann nur noch im Scriptcode.
