Suggestions to this dilemma?

[Anon]

I create entries in a file. Each entry takes up one line. Problem is, on this line form data is stored. How can I stop multiple line message fields from creating new lines when a user puts in a return or enter?

Replace all your newlines with a space:

$fixed = ereg_replace("\n", " ", $notfixed);

Then something like:

$fp = fopen("$path$listfile", "a");
fputs($fp, "$fixed\n", 100); // limit to 100 bytes ;-)

Will the message they type still read with breaks?

[petrb]

Assuming they are in a textarea which has the wrap="physical" attribute (Netscape needs this), the text they enter will break as they type it. What we are replacing are any "enter" keystrokes.

Keep in mind that you may have to replace \r\n together, since on some systems, I can't remember which 😉 that happens when a user hits the "enter" key.

In that case, you might prefer to use nl2br() instead:

$fixed = nl2br( $not_fixed );

You can also do...
$fixed=str_replace("\n",'\n',$mystring);
...before writting and, when reading....
$mystring=str_replace('\n',"\n",$fromfile);
.. after read the string from file.
So yo will get the original content of the string.

If the text is edited in a "TextArea" html control, you must
replace also the CR characters as follows...

$fixed=str_replace("\n",'\n',str_replace("\r",'\r',$mystring));

..or in a more more compact style...

$fixed=addcslashes($mystring,"\r\n");

and to rebuild the original string...

$mystring=str_replace('\n',"\n",str_replace('\r',"\r",$fixed));
