[SOLVED] Capital Letters error

[env3rt]

I'm making my own htmlEntities thingy because I want certain codes to work and others not to. The problem is that if I ban < br > then you can still do things like < BR > and stuff

<?php 
function htmlfilter($badcodes){

$filout = array(

"<br>","<BR>","<Br>","<bR>","<P>","<p>"

);
$nobadcodes = "<nocode>";
foreach($filout as $replace){
	$badcodes = str_replace($filout,$nobadcodes,$badcodes);
}
return $badcodes;
}
?>

So basically I need something to ignore capital letters, because I don't want to type every possible combination of capital letters and normal letters for each code (like above)

Please help, ask if you need further information.

Sorry, I meant str_ireplace()

I'm making my own htmlEntities thingy because I want certain codes to work and others not to.

 

an existing function already provides for this:

 

strip_tags ( string $str [, string $allowable_tags] )

 

$content = strip_tags($content);

 

if you want to allow <UL> and <LI>, for instance,

 

$content = strip_tags($content, '<UL><LI>');

 

 

 

ah, but this doesn't replace does it?? never mind..

[code=]<?php 
function htmlfilter($badcodes){

$filout = array(

"<br>","<p>"

);
$nobadcodes = "<nocode>";
foreach($filout as $ireplace){
	$badcodes = str_ireplace($filout,$nobadcodes,$badcodes);
}
return $badcodes;
}
?>

Would that be what you do just replace the to "replace"'s with ireplace?

Because it's not working

[BlueSkyIS]

remove the for, we're sending the whole array in one shot:

 

function htmlfilter($badcodes){

    $filout = array("<br>","<p>");
     $nobadcodes = "<nocode>";
return str_ireplace($filout,$nobadcodes,$badcodes);
}

[Yesideez]

<?php 
function htmlfilter($badcodes){
  $filout = array('<br>','<p>');
  $nobadcodes = '<nocode>';
  $badcodes=str_ireplace($filout,$nobadcodes,$badcodes);
  return $badcodes;
}
?>

 

Try that. I enclosed the text with single quotes instead of double.

That's not working

  $nobadcodes = '<nocode>';
  $badcodes=str_ireplace($filout,$nobadcodes,$badcodes);
  return $badcodes;
}
?>

not working either

[Yesideez]

Have you checked that your data is being passed to the function correctly?

[BlueSkyIS]

yes, can we see at least a partial example of $badcodes?

[env3rt]

Well the original code worked properly so I assume that the other codes are wrong.

 

Not sure what you mean by see partial example of $badcodes

[BlueSkyIS]

that is, can we see an example of what you are sending to the function to test it, the HTML?

[env3rt]

<?php
include("htmlfilter.php");
$sig = $username."sig.html";
$fh = fopen($sig, 'r');
$sigpage = fread($fh, filesize($sig));
fclose($fh);
if($_POST['sigupdate'])
       {
$fh = fopen($sig, 'w');
$filterhtml = htmlfilter($signature);
fwrite($fh, $filterhtml);
fclose($fh);
echo "<script type='text/javascript'>
window.location = '/$username.php'
</script>";
}


echo"
<center>Update your signature!
<form method='post' action='?signature'>
<textarea name='signature'>$sigpage</textarea>
       <input type='submit' value='Submit' name='sigupdate'>
</form>
Your sig is now:<br>
$sigpage
</center></marquee></font>
";
?>

 

I would really like it if you could just switch the replace to ireplace from the original code for me because the original code was working, and I don't know how to do it

Fatal error: Call to undefined function: str_ireplace()

Does that mean that str_ireplace doesn't work on my server?

[env3rt]

<?php

function htmlfilter($badcodes){

  $filout = array('<br>','<p>');

  $nobadcodes = '<nocode>';

  $badcodes=str_replace($filout,$nobadcodes,$badcodes);

  return $badcodes;

}

?>

 

that works but once I change the replace to ireplace it stops working

Fatal error: Call to undefined function: str_ireplace()

Does that mean that str_ireplace doesn't work on my server?

 

yes, apparently so. it is a PHP 5 function and you probably have PHP 4.

[env3rt]

Damn so I guess I can't really do it properly then

[BlueSkyIS]

you can, but you'll have to use something less fun like preg_replace().

[env3rt]

Could you show how to insert it into my code

Or could you possibly disable capital letters

[darkfreaks]

you need

 

str_replace

 

it will work with php 5 and 4

[env3rt]

you need

 

str_replace

 

it will work with php 5 and 4

Lol I have been using that all along but it is case sensitive and I don't want it to be, so they suggest str_ireplace but I have php 4

[BlueSkyIS]

hence the correct solution: preg_replace()

 

 

[env3rt]

I don't understand preg_replace, well I do but not how I could use it to help, unless I switched all the caps letters to non caps
