Problem with strip_tags() pls help!

evo4ever

Hi ppl. Im back here concerning the function "strip_tags()" I have a function called "verify_profile()" the source code is:

function verify_profile($formdata, $mid) {

$error = "";
$formdata = strip_tags($formdata);

$insert_check = update_profile($formdata, $mid);

if ($insert_check != "true") 
	return($insert_check);

return("");			
}

When I change my profile, i test to see if strip_tags is working by putting in some HTML. I submit the form and the whole data gets changed to a capital "A"! the tags get removed but it also changes the formdata. Every feild (eg, username, profile etc) gets replaced with an "A"!!! why?? this is very strange! help appreciated! thx.

I think you're getting the "A" of "Array". I suspect that your $formdata is an array, but strip_tags should be called with a string, not an array of strings. So you'll need a loop to loop through each string and call strip_tags on each one of them.

Ok. I've just wrote up a function for strip_tags with a loop in:

function remove_html_tags($formdata) {

foreach($formdata as $key => $value)
{
	$key = strip_tags($key);
	$value = strip_tags($value);
}
return $formdata;
}

Is this ok? I havnt tested it yet, i just want to clarify if its ok.

No, I don't think it's ok.

The reason is because $key and $value are copies of the elements of $formdata. Therefore when you return $formdata, it's still unchanged! If you want to modify the elements of $formdata, then you have to use a while loop and each(). See here for sample code on how to iterate through array.
