PHP Guestbook wont accept Colon ( : ).

[fresch]

Hi

 

I just implementet a PHP Guestbook in my Flash site, and it works almost perfectly.

But i have one problem.

 

Every time i try to write on the guestbook, and include a Colon : <---- , it wont work.

How do i make it work?

 

You can see the guestbook here:

 

http://www.meny-graphics.dk/blog

 

by pressing "Mere" under the first entry, and scrolling down.

 

The PHP file can be found here:

 

http://www.meny-graphics.dk/blog/GuestBook.php

 

Thanks in advance!

You need to post the actual code, as we cannot see the code from the .php file. Post it inside of

tags.

Anyone?

Can you post the data found in GuestBook.txt ?

 

I can only see it stripping : from some data, and it appears to be splitting data in the GuestBook.txt file on the delimiter: .:::.

 

Maybe the semi colon is interfering with the guestbook file's delimiter some how?

 

PS: function "split" is being outdated from php v6.0 onwards, you should change it to str_split

Thanks for the answer ! Though i didnt understand much of it Im pretty new to this.

The GuestBook.txt is completely empty, when noone has posted on the guestbook.

 

Its funny - i also had problems posting special characters (ÆØÅ), but i found someone on another random forum who said that i should insert

 

$Comments   = htmlspecialchars($Comments);

 

in the beginning of the php.

I did that, and it worked.

 

Now i only need it to accept Colon, so people can post smiley faces, web adresses, etc

Does anyone have a solution?

Are they being removed using eregi_replace

 

Try removing the following lines

 

$Name 		= ereg_replace("[^A-Za-z0-9 ]", "", $Name);$Email 		= ereg_replace("[^A-Za-z0-9 \@\.\-\/\']", "", $Email);$Comments   = htmlspecialchars($Comments); $Comments   = nl2br($Comments);$Website 	= ereg_replace("http://", "", $Website);$Website 	= ereg_replace("[^A-Za-z0-9 \@\.\-\/\'\~\:]", "", $Website);

 

Then try it, just to see if its one of them....

Thanks for the answer.

I tried to remove all the lines, but it didnt change anything.

try removing

 

$Comments = stripslashes($Comments);

 

to test.

 

Where is the form posting the information to this file?

That didnt work either.

 

It works this way:

 

I have a Flash File, with soem GuestBook Flash (AS2) code on it.

When someone fills in the name, and comment fields, and press "Tilføj Kommentar" (Submit), The PHP file writes the comment, into the GuestBook.txt file.

The Flash site, then shows the GuestBoox.Txt file.

 

 

 

I tried almost all the charaters i could find, at it posts perfectly, EXCEPT if the message includes a Colon.

This is very wierd.

 

Try it out.

@fresch, the issue may not be PHP at all. It is most likely on the flash end side. I would do a search about flash removing colon's from posts and see what you come up with. In that code I do not see how it would be removing the colon.

 

The true way to test is echo out $_POST['comments'] before you do anything to it, as this will tell you if the data is coming in without the : or if the colon was removed prior to being posted.

Use a proper relational database.

I have looked everywhere, and i cant find anyone who has the same problem.

This is really wierd

[Catfish]

When you say,

This is very wierd.

what exactly do you mean?

 

If the user inputs a colon and clicks submit, it will not save the guestbook data?

If the user inputs a colon and clicks submit, it saves the data, but then when viewing it will not show the post correctly?

Does it save partial amounts of the data if there is a colon? Does it save data up to the colon but nothing beyond?

 

Describe exactly what is failing, and what is working and we might be able to narrow down where the problem is.

[fresch]

Sorry for Bumping this thread - After almost 2 years, i went back to continue working on the site.

And i still have the problem - Whenever i type a Colon in the guestbook, i can't post it.

 

The "Add Comment" button simply does nothing.

Every other character i tried worked fine.

 

You can test it out, by checking the it out here:

 

http://www.meny-graphics.

 

use the oldest Blog Entry, to test with (Click Comment).

 

Thanks a lot for the help so far guys - I really hope to get this solved.

I tried commenting you're right it doesn't POST if the comment string contains a colon.

 

I suspect it's an issue with the Flash. Maybe something wrong with the ActionScript?
