Hi!

I've made some helping requests here in this forum, and I always get help from you guys. I'm counting on you this time too.

Here's the problem I need help with.

I have a textarea and I'm sending the data inside with a POST and get it on another page with .php as a string.

I need javascript to check how many lines there are and put a certain string (for example: "<br />" at the end of every line.

Is it possible to do this?

We can maybe use another hidden form element to store the data "textarea with the <br>s"...

So any help here would be much appreciated.

THANK YOU!

Okay. I messed the first post up a little...

The main thing I want to do is to connect to a database and get the text data from there and then output the data with \n as a javascript alert box.

I made a little sample code and it does not work!

Can you please have a look at it for me?

<?php
// connect and get the data is fine
$textarea = "Hi!
My name is Bond.
James Bond!"; // This is the text
 
 
$text_separated = nl2br($textarea); // Do the trick you showed me!
$array = explode("<br />",$text_separated); // I make an array from the textarea divided the parts that need a line break
 
echo "<script type='text/javascript'>alert('"; // start of the javascript alert
 
foreach($array as $key => $value){
echo $value; // write the text
?>\n<?php // to show the line break
};
 
echo "')</script>"; //finishing the javascript
?>

The most hurting part is that if I change the $value into a random string it does fine!

Javascript doesn't allow newlines in the text itself. Trim them off and you're fine:

PHP Code:

<?php
// connect and get the data is fine
$textarea = "Hi!
My name is Bond.
James Bond!"; // This is the text


$text_separated = nl2br($textarea); // Do the trick you showed me!
$array = explode("<br />",$text_separated); // I make an array from the textarea divided the parts that need a line break

echo "<script type='text/javascript'>alert('"; // start of the javascript alert

foreach($array as $key => $value){
echo trim($value); // write the text
?>\n<?php // to show the line break
};

echo "')</script>"; //finishing the javascript
?>

Thank you very much it works perfectly!

Wonderful!
