Paypal_lib Success Page Problem

[eluser]Jesse Schutt[/eluser]
This code is in the "Success" view of the Paypal_lib. It is not displaying any information regarding the _POST information. Actually, it isn't displaying anything at all other than the "Success, Your Payment was received..." Any ideas?

Code:

<h2>Success!</h2>

<p>Your payment was received using Paypal.</p>

&lt;?php if($this->input->post()): ?&gt;
<p>Here's its information:</p>
<p><code>
&lt;?php    
    foreach ($this->input->post() as $key => $value)
        echo '<strong>$key</strong>: $value <br/>';
?&gt;
</code></p>

&lt;?php endif; ?&gt;

If I insert the following, I can see results, so I am pretty sure that there is _POST data.

Code:

<?php
if (isset($_POST))
{
   print "<pre>". htmlspecialchars(print_r($_POST, TRUE)) ."</pre>";
}
else
{
   print '$_POST not set!';
}
?&gt;

I'm curious as to why print_r works and not $this->input->post()...

[eluser]missionsix[/eluser]
since this:

$this->input->post()

is a method, its going to check if the key passed has an associated value. Since you are not passing a key, there is not key / value pair to check it against in $_POST, so its going to return false, which is why you can't see anything.

Thanks for the response MissionSix!

As I'm sure you can tell, I am just learning how to get around in all of this.

What would you suggest I do to access the values held in the $_POST array?

Thanks Much!

If you want to loop through them, I'd simply use the $_POST array, seeing as

$_POST[$key] == $this->input->post($key) == $this->validation->$key

[eluser]missionsix[/eluser]
loop through the $_POST[$key]'s, but reference the $_post data through $this->input->post($key). This way your input will be cleaned before use (xss filtering, etc)

[eluser]Jesse Schutt[/eluser]
Thanks for the help. If it's not too much trouble, could you give me a sample of what you mean? I am doing my best to learn all of this.

[eluser]missionsix[/eluser]
Yeah, sure:

From your example:

Code:

<h2>Success!</h2>

<p>Your payment was received using Paypal.</p>

&lt;? if($_POST): ?&gt;
<p>Here is its information:</p>
<p><code>
&lt;?php    
    foreach ($_POST as $key => $value)
        echo '<strong>'. $key .'</strong>:'. $this->input->post($key) .' <br/>';
?&gt;
</code></p>
&lt;?php endif; ?&gt;

you were also having problems with your echo statement. You used single quotes with enclosed Vars and that won't work in php.

Thank you very much! I'll go through this and see if I can't figure it out for myself.

I really appreciate your help.

So it really doesn't matter which one you use: $_POST[$key], $this->validation->$key or $this->input->post($key), they're all the same.
