function doesnt work, doesnt output data

[jesushax]

hi below is my function

 

f
unction paragraphs($data) {
$data = str_replace('<br />', '', $data);
$data = preg_replace('%\A\s*<p>|</p>\s*\z%', '', $data);
htmlspecialchars($data);
}

 

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

 

i didnt create the function code i just sued it but the idea of the code is to

remove the <p> if the data sent has one at the begining

remove the </p> if the data has one at the end

remove all <br /> tags

 

thanks for any help

 

at the moment the function posts nothing, blank data only...

htmlspecialchars($data);

//Should become:

return htmlspecialchars($data);

 

Orio.

thanks a bunch

[jesushax]

just looking at the code

 

function paragraphs($data) {
$data = str_replace('<br />', '', $data);
$data = preg_replace('%\A\s*<p>|</p>\s*\z%', '', $data);
return htmlspecialchars($data);
)

 

htmlspecialchars converts say > to >

 

but i want the <p></p> html tags in the middle i just want the ones removed from the end and the begining if there are any if there arent do dont anything, the code above do this?

You could use strip_tags() and then add <p> and </p> to the beginning and end of your text.

but i want to keep <p></p> tags in the middle of my text i dont want wht wones at the begninig

 

strip tags would keep them all wouldnt it?

Use the optional $allowable_tags parameter:

 

strip_tags($data, "<p>")

 

This won't strip <p> tags.

Sorry, I didn't read your post properly.

 

well, one thing you could do is:

 

<?php

$text = '<p>This is some text. <p>Another paragraph</p> Some more text</p>';

if(substr($text, 0,3) == '<p>' && substr($text, -4) == '</p>') {

	$text = substr($text, 3);
	$text = substr($text, 0, -4);
}

echo $text;
?>

ok heres my finale, this good?

 

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);
echo $data;

 

so all other html will be stripped apart from <p> tags

then if it begins or ends with <p> it will be removed

then any <p> inside the text will be replaced with </p><p>

 

what about symbols like & and ' they come up as & etc.. are they classed as html tags will they be stripped?

 

Thanks

[jesushax]

final one is here

 

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);
echo $data;
}

 

this work well?
