[RESOLVED] Passing slashes and dots in form values

kamy99

Hi:

I'm using cURL to pass info to an API.
The info is gathered through a form.

Some of the form fields must contain and pass slahes and dots to the API.
For example: 172.198.2.2 and http://www.google.com

When I display the results on the page before submitting the info, everytihng looks OK. However when I submit data, it seems any spaces are shopped and the slashes and dots are causing problems.

I think I need to pass the values through a PHP function, but I just can't figure out which one!
Not sure if it'd be htmlspecialchars or htmlentities or another function.

Thank you for your help in advance 🙂

I'm guessing that [man]urlencode/man is what you are looking for.

after further testing, it seems that any spaces in the passed values are creating this problem.
For example if in the name field they type Foo Bar , the problem is created, if they type FooBar it's ok!

Any ideas?

If you are talking about characters replacing spaces in form field names on post, I think your only solutions are to either remove the spaces from the form field names, or use something like [man]str_replace[/man] on the field names.

i.e.

$post = array();
foreach($_POST as $key => $value)
  $post[str_replace("_", " ", $key)] = $value;
$_POST = $post;

I trust to use base64_encode and decode back.

Yes, that should be appropriate too, though I think url encoding may be more appropriate in this case.

In other words: suppose you have an array of data you want to post to another form:

$curlPostData = array();
foreach($postDataArray as $key => $value)
{
   $curlPostData[] = $key . '=' . urlencode($value);
}
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, implode('&', $curlPostData));

It turned out the problem was not in my php code, rather in the API that was parsing the info.
A simple str_replace tweak did the job.

Thank you for you replies and help.
