How do I link a snippet of php to a form action?

I’m just curious if there’s any special code I need to use, or if it would just look like this;

action="[[phpSnippet]]"

or if I just need to upload the php to a folder and link it like normal.

Not quite.

You need to either:

1) Put the snippet on a separate page and make the action a link to that page action=[~##~]" (where ## is the id of the page with the snippet).

2) Put the snippet on the same page and have the form post to itself action="[~[*id*]~]". In that case the snippet needs to make sure it’s a repost before acting.

1. I’m guessing the page it’s posted on needs to have a completely blank template applied to it.

2. What do you mean by "making it a repost"? I didn’t see any option for it in the snippets options.

Sorry if I’m bugging you. I got a user page-creation form working using a form outside of the CMS(by editing the database), but now I need to test my user session recognition feature while logged into the CMS.

Here is a simple example of posting a form back to the same page:

Here is a simple example of posting a form back to the same page:

<?php
/*  Example login form
    * form posts back to the same page
    
    usage: uncached   [!ThisSnippetName!]
*/
$output ='';

// get the current document id to use in the action of the form
$this_docid = $modx->documentIdentifier;


// if the form has been posted
if(isset($_POST['submit']) && isset($_POST['password'])){

  // do whatever actions here if the form has been posted
  $output .='<div align="center">Welcome '.$_POST["webusername"].', you are logged in...</div>';

}else{
// otherwise show the form
  $output .='<form id="loginForm" name="loginForm" method="post" action="[~'.$this_docid.'~]">
    <table width="300" border="0" align="center" cellpadding="2" cellspacing="0">
      <tr>
        <td width="112"><b>Login</b></td>
        <td width="188"><input name="webusername" type="text" class="textfield" id="webusername" /></td>
      </tr>
      <tr>
        <td><b>Password</b></td>
        <td><input name="password" type="password" class="textfield" id="password" /></td>
      </tr>
      <tr>
        <td> </td>
        <td><input type="submit" name="submit" value="Login" /></td>
      </tr>
    </table>
    </form>';
    
}

return $output;
?>

So I input my form at the bottom, put my current php code inside the output below this line ;

// do whatever actions here if the form has been posted

and insert the snippet onto the page?

Alright I got the other page working. My script worked too . Now to move on to the next phase.
