thanks ??

and have you other good Information for a secure contact form

Can you show me an example how to use the command right please ..

would it work with str_replace instead of trim?

Ok, thanks for your help!

I mean with "does not work":Normally i thought that trim strips "n". But if i enter in the input field name: "Maxn" the result is "Maxn". You can also test it. It strips not completely "n" only slash and that was irritating!

Thanks! I will test it. ??

I am thankful for any help, link, tutorial etc. to secure my contact form!

If i use trim on a string it strip all characters you post … for example: $name = nMax Mustermann; echo trim($name); output: Max Mustermann but with $_POST it strips only whitespaces … for example: <input type="text" name="name" /> // nMax Mustermann $name = $_POST["name"]; echo trim($name); output: nMax Mustermann I am trying to avoid line breaks etc.

If i use trim on $_POST it trim only whitespaces. It ignores the rest that is my Problem.Should i use something else instead of trim for a secure validation?

Ah okay thanks!

Sorry that was a copy and Paste mistake.I also tried the example on w3 school but it doesn't work.The trim Command don't delete n,t,r, etc.

Hey,I am trying to code a form validation but i get a problem with the function "input_check()" on w3 website especially with the trim command. It don't trim anything.$name = test_input($_POST["name"]);function test_input($data) { $data = trim($data); $data = stripslashes($data); $data = htmlspecialchars($data); return $;}echo $name;I am thankful about any help.
