é causing 'not acceptable' http error

coldwerturkey

In a form, when the character 'é' is passed onto the processing of the form to be stored in a database, I get the following error

406 Not Acceptable
An appropriate representation of the requested resource /admin.php?... could not be found on this server.

(I know its not a me issue because only when the é character is present in the form do I get the error)

I run all the post data from the form through the following function..

function cleancode($Text) {
	// Fix line breaks
	$Text = str_replace( "\r", "", $Text);
	$Text = str_replace( "\n", "<br />", $Text);
	//Fix apostrophes
	$Text = str_replace("’","'",$Text);
	$Text = str_replace("‘","'",$Text);
	//Fix e
	$Text = str_replace("è","e",$Text);
	$Text = str_replace("é","e",$Text);
	//Try again to fix e
	$Text = ereg_replace("(È|É|Ê|Ë|è|é|ê|ë)","e",$Text);
	//Anti - SQL injections
	$Text = mysql_real_escape_string($Text);

//...
}

But doesnt seem to work, I still get the same error...

Am I missing a basic function or encoding or something that takes care of special characters like the é?

Please help,

While I cannot solve your issue, I would like to comment on this line:

 $Text = ereg_replace("(È|É|Ê|Ë|è|é|ê|ë)","e",$Text);

You should use preg instead of ereg (as PHP 6+ will not support any ereg type regular expressions.. future proof now your code):

$Text = preg_replace('#[èéêë]#i', 'e', $Text);

Is that error generated when you submit the form or click a link in the browser, or is the script itself doing some sort of cURL or other HTTP request that is causing it? (The error appears to be coming from Apache, not from your PHP.)

The error happened when submitting the form, I got the same error with the character when using below;

<?php
if (isset($_GET['do'])) {
	echo $_POST['test'];
}
?>
<form action="test.php?do" method="post">
<input type="text" name="test" />
<input type="submit" />
</form>

but got no errors when I tried it on my other servers!

so you're right NogDog, its the server.

The host of the server is a local guy in a one horse town, not a big company, does anyone know what this error refers to in apache, or is called.. like if saying "I'm getting a http 406 error when I try to post the é character" makes no scene to him?

It may be an over-zealous or poorly configured mod_security set-up in the server's Apache configuration. You could try to bypass it with the following in a .htaccess file in your web page's directory and see if that fixes it. If so you can then at least ask the server admin to look at the mod_security setting and see if it should be amended, disabled, upgraded, or whatever.

.htaccess:

<IfModule mod_security.c>
SecFilterEngine Off
SecFilterScanPOST Off
</IfModule>
