function paragraphs($data) {
strip_tags($data, "<p>");
if(substr($data, 0,3) == '<p>' && substr($data, -4) == '</p>') {
$data = substr($data, 3);
$data = substr($data, 0, -4);

str_replace("<p>","</p><p>",$data);
str_replace("</p><p></p><p>","</p><p>",$data);

You need to return data  to the calling script.

<?php
function paragraphs($data) {
    strip_tags($data, "<p>");
    if(substr($data, 0,3) == '<p>' && substr($data, -4) == '</p>') {
      $data = substr($data, 3);
      $data = substr($data, 0, -4);
   }
   str_replace("<p>","</p><p>",$data);
   str_replace("</p><p></p><p>","</p><p>",$data);
   return($data); // added the return statement
}
?>

a i see silly me thanks

 

but now im having trouble with the actuall function itself

 

its still posting <br /><br /> values after ive took them out?

 

function paragraphs($data) {
strip_tags($data, "<p>");
if(substr($data, 0,3) == '<p>' && substr($data, -4) == '</p>') {
$data = substr($data, 3);
$data = substr($data, 0, -4);
}
str_replace("<br /><br />","</p><p>",$data);
str_replace("<br />","",$data);
str_replace("<p>","</p><p>",$data);
str_replace("</p><p></p><p>","</p><p>",$data);
return($data);
}

can you give example(s) of what $data is supposed to hold?

 

 

[jesushax]

gets its value from a form

 

$Case = paragraphs($_POST["txtCase"]);

 

and the form just has basic text inputted in it

try adding $data = ... before all your str_replace(...);

 

function paragraphs($data) {
strip_tags($data, "<p>");
if(substr($data, 0,3) == '<p>' && substr($data, -4) == '</p>') {
$data = substr($data, 3);
$data = substr($data, 0, -4);
}
$data = str_replace("<br /><br />","</p><p>",$data);
$data = str_replace("<br />","",$data);
$data = str_replace("<p>","</p><p>",$data);
$data = str_replace("</p><p></p><p>","</p><p>",$data);
return($data);
}
