text area putting new line in middle of url/img

emrys404

I am having users input text from a text area and then output it to another page ie. a forum, or a submit news type page. I used nl2br() to keep it all from going on a single line and it also worked fine for html links and images that werent too long. However sometimes it will but a <br> in the middle of my my <a href or <img scr if they are too long. it gets quite annoying. are there any neato functions to make sure the html gets process right while keeping the new lines? Or even not so neato functions?

Thanks

Instead of using the nl2br() function, do it this way.

1). Post it regularly to the second page.

2). on the second page do something like this:

$var = $_POST['var'];
$text = wordwrap( $var, 20 );

echo "$text";

You can change the 20 to whatever you want.

Wordwrap() will just put new lines (\r\n) in where it feels best (between "words"--this also includes HTML), which will give him the exact same problem.

emrys404, do you by chance have new lines inside the HTML? That's the only time nl2br() should ever put a <br> inside the tag, since it reads the new line there.
You could, theoretically, construct a regular expression that will check whether or not a new line is inside an HTML tag, and then replace it depending on the result. I'm not that great with regular expressions, however, so I can't write it for you.

I hope this helps with the problem. Here's how I would go about it--find all the new lines inside HTML tags via regexs, and then remove them. After they are all removed, run nl2br() on the text.
You'll lose all the new lines inside the HTML, but that shouldn't matter.

Oops...misread the problem.

Thanks for the input. As for new lines in the html.. i couldnt figure out why it was doing that. the only thing i could figure out was the autowrap on in the text area was doing it some how... Anyway thanks for the tip about searching for new lines in the html with regex. I'll give that a shot even though i dont know who the new lines got in the html in the first place... Hmm, now that i think about it, if i had a statment like</a href ="yaydaya"><img src= yad yda it would put the new line after the img....

Okay, thanks for the tip i'll try it out and let you know...
