Applying functions question

[graham23s]

Hi Guys,

 

say i have $_POST data to deal with to add spaces and line breaks:

 

$_POST['message'];

 

i usually do:

 

  $message      = nl2br($message);

  $message      = addslashes($_POST['message']);

 

Is there a certain way to apply both functions on the same line like:

 

  $message      = nl2br(addslashes($message));

 

or

 

  $message      = addslashes(nl2br($message));

 

or doesn't it matter in what order?

 

thanks guys

No, but I would suggest against using addslashes as it is in the process of being depreciated.

 

If you are filtering this for db entry use mysql_real_escape_string instead and no it does not matter which order you use. And I would suggest storing the data in it's raw format and use nl2br before you display the data to the user.

Hi Premiso,

 

it's really for a contact form, i will be e-mailed a copy of the message, does that make a difference?

 

thanks mate

Well I would not addslashes then, there is no need to. If you do it will look like this:

 

Hello I can\'t decide...

 

Etc. So remove that part, and if it is not an html email, the nl2br will not do much good. I think the basic text will display like it should with the line breaks. If it is html, then yea use the nl2br.

If you call,

 

nl2br(addslashes($message));

 

It will perform the addslashes then nl2br.  In some cases it can make a difference.
