[SOLVED] How Can I Make This Not Case Sensitive? Someone... ANYONE? Pretty Please :o)

[thisisedie]

Hi there. I've been using a simple mail form which I found online ages ago and modified to death. Now I'm trying to add a verification (my own creation -- to get rid of the spam I'm suddenly getting) which works great except it insists on being case sensitive.

 

Ok so (sorry I'm not very technical) -- at the top I have: $badbot = yellow;

 

Below the textarea box I have a picture of bananas that asks what color bananas are.

 

In the area that defines the errors I have:

 

if (strlen($bots <> $badbot)) {

$error = true;

$error4 = errorBots;

}

 

The results are that if someone types in "yellow" it works fine but "YELLOW" or yElloW", etc throws up the error. Any help would be greatly appreciated!

strtolower them first

[thisisedie]

I was looking at the earlier and couldn't make it work. I tried:

 

$badbot = "yellow";

$badbot = strtolower($badbot);

echo $badbot;

 

I'd like to note that I know this is probably simple and the reason I'm clueless is because I haven't done much PHP programming (or any other kind for that matter). Mostly I've just dabbled

well in your example yellow is already lowercase so it's not like strtolower is doing anything to it.  Did you apply strtolower to the user's input?

[thisisedie]

Did you apply strtolower to the user's input?

 

 

*cough* how would I do that?

Okay for example, if the input field in the form is named "answer" :

 

<?php
  $answer = "yellow"; // this is the answer you are comparing to the user's input
  if (strtolower($_POST['answer']) == $answer) {
    // case insensitive match!
  } else {
    // error stuff here
  }
?>

Thanks so much for your help... but that didn't work. Maybe I didn't make it clear what I'm trying to do. I don't want the input to be case sensitive. So if the user were to type in yellow, YELLOW, or YELLow, etc, they'd all work.

You're so not getting the logic.

 

The if statement should read something like this -

 

if (strtolower($user_input) === strtolower($bot))

 

If you use strtolower for both the user input and the variable, then both will be lowercased for the if conditional.

[.josh]

what I posted is an example of making it case IN-sensitive.  So if that didn't work then you did something wrong.  Perhaps you should post your form and what you're actual code. It's case insensitive because you are making everything lowercase before comparing it.

[thisisedie]

Heh Ken I'm really NOT getting it. As I said, I don't have much experience with PHP. CSS is another story. I'm the CSS Queen! Thanks for your patience guys 

 

I've tried making your suggestions work with my code and can't figure it out so I guess I'll go ahead and post the entire code. Thanks again

If you want case-insensitivity, make both of them lower case (or uppercase, it doesn't matter). 'Foo' != 'foo', but because strtolower('Foo') == 'foo', strtolower('Foo') == 'foo', but also strtolower('FOO') == 'foo' and strtolower('foO') == 'foo' and so on. Get it?

[thisisedie]

Yep I get it... I just don't understand how to implement it because apparently I'm a big ole PHP dummy LOL. Either that or I'm too tired to think. So I'm just gonna give up for now and tag a little note telling users to type in lowercase. Sigh. Thanks so much for all your help 

[Daniel0]

Change

if (strlen($bots <> $badbot)) {

to

if (strtolower($bots) != strtolower($badbot)) {

[thisisedie]

I take it back! It worked! It worked!  ;D

[thisisedie]

Thank you, thank you, thank you!
