I've created an input form for a friend of mine.

I need to figure out a way to automatically add <p> tags to his input. Even though he enters the text as paragraphs, it gets entered into the database without any formatting. I hope I'm not being too vague.

Any ideas on how to do this?

Just concatenate it together with .
PHP Code: [ Select ]
$formatted = '<p>'.nl2br($input).'</p>'

nl2br will convert line breaks to html <br> tags too.

Not being able to add it despite entering <p>text</p> suggests that the input maybe is "cleaned"/sanitized and that there may be some text altering functions added before going to the database such as "striptags()".

This is true, I should have pointed out that this should be after pulling that data out of the database when you're prepping it for output. I didn't even notice the OP said it was going into the db without any formatting (which is exactly how it should be).

I may have been to vague. I can indeed add the <p> tags. My problem is that there is more than one paragraph most of the time. How can I detect news paragraphs and add the tags accordingly?

Posting some code (or just "typical" user input that need <p> tags, and where) could be helpful.

Just put everything you can think of that would define a paragraph into an array, then pass that to str_replace as such:
PHP Code: [ Select ]
trim($data);
$data = str_replace($paragraph_markers,'</p><p>',$data);
  1. trim($data);
  2. $data = str_replace($paragraph_markers,'</p><p>',$data);

I'm not sure I follow. The only thing that would indicate a new paragraph would be the user hitting the "return" key.

Then that's what you're going to have to match on. Something like:
PHP Code: [ Select ]
$paragraph_markers = array("\n\n","\n");

So the user will have to input the "/n" when he enters the data?

"\n" is what gets stored every time the user hits the enter key.

Heh... I must have overlooked that. Ugh. Thank you very much!
