   The following code was written for the following conditions:
   1. MachForm version 2.4
   2. The "Redirected URL" already has some parameters. For example, http://xx.xx.xx.xx/process_form_data.php?form_name=template&itemcode=123432

   To send the form data to a php program, replace the line

   $commit_result['form_redirect'] = $form_redirect;

   in includes/post-functions.php with the following code (probably should be a function instead):

   $url_data = '';
   $entry_details = get_entry_details($form_id,$new_record_id,'');
   foreach ($entry_details as $data) {
       if ($data['element_type'] == 'textarea') {
           $data['value'] = nl2br($data['value']); //add br before newline
           $data['value'] = str_replace("\r\n", '', $data['value']); //remove newline because it breaks php
       }
       elseif ($data['element_type'] == 'file') {
           $data['value'] = strip_tags($data['value'], '<a>'); //remove the image tag, but keep href
       }
       elseif ($data['element_type'] == 'checkbox') {
           $data['value'] = strip_tags($data['value'], '<br>'); //remove the image tag, but keep <br>
           $data['value'] = str_replace('', ',', $data['value']); //replace <br> with ','
           $data['value'] = preg_replace ('/^ /', '', $data['value']); //remove the beginning space
           $data['value'] = preg_replace ('/,$/', '', $data['value']); //remove the trailing ','
       }
       elseif ($data['element_type'] == 'phone') {
           $data['value'] = str_replace(' ', '', $data['value']); //remove spaces
       }
       elseif ($data['element_type'] == 'address') {
           $data['value'] = str_replace('', ', ', $data['value']); //prefer ',' over <br>
       }               
   
       //target php program fails to get some data values correctly due to existence of non-alphanumeric characters
       $data['value'] = urlencode($data['value']);
   
       //replace '&nbsp;' with nothing, because empty fields have '&nbsp;' after using urlencode() previously
       $data['value'] = str_replace('%26nbsp%3B', '', $data['value']);
   
       $url_data .= $data['label'] . '=' . '"' . $data['value'] . '"' . '&';
   
       //fwrite ($mlog, $url_data . "\n"); //for testing only
   }               
   
   $commit_result['form_redirect'] = $form_redirect . '&' . $url_data;

   I have added the following code to your procedure.

   $mlog = fopen("test.txt","w");
   fwrite ($mlog, $url_data . "\n"); //for testing only
   fclose($mlog);

   But I can not find the test.txt file anywhere, so
   I created the file and set its permissions to 666. But the file never gets updated.

   Does this file get written only if there is a redirected url, Or does it create the file for every form that is completed?

   Thanks.

   I am not sure why but it seems like this code is not getting executed at all. Just for testing I have put in sleep(10000); and it still just jumps to the redirect page without any pause. what the?

   I think the code above assume that you need to enable "form review" for your form. So try to enable form review.

   I've always tested with "form review" on and never thought about it, but I just tested with it off and it does not work. I didn't realize this. I didn't review the entire code to see where I should put the code because I was referred to post-functions.php. I guess it's a question for the developers as to where this code should go if "form review" is off.

   To answer the question "Does this file get written only if there is a redirected url,",
   the answer is "yes".

   form review, did the trick. Thanks.

   Also your code seems to create a malformed post. The data returned starts with a & instead of a ?, did you do that on purpose?

   I also added to following code in case it helps anyone.

   //append the newly created record id to the $url_data stream
   $url_data .= 'RecNo=' . $new_record_id; //unique number for this form submission

   //saves the $url_data to a file so you can inspect it
   file_put_contents("/(path)/POST_FUNCTIONS.txt",$url_data,FILE_APPEND);

   I start with & instead of ? in "$form_redirect . '&' . $url_data" because I'm assuming that $form_redirect will already have some parameters (see #2 in the first post), since this is how I use it. I suppose this part can be improved by checking to see if '?' exists in $form_redirect already, and if not, then use '?' instead of '&'.
