PHP - Function Call In Foreach()

Hello,

I am new to PHP and have come to a grinding halt in my project. I am attempting to dynamically generate values for Wordpress shortcodes ( [example] ). I have successfully created the shortcodes and am having trouble setting their value. When I call the function that is supposed to return the value for the shortcode, it returns empty. I can however hard code a string and have it returned to the function, thereby manually creating a value for the shortcode. However, because the shortcodes are being generated and filled dynamically, I need this function to work without specific values. I know this may sound like a Wordpress specific question, but I have a feeling it's just my lack of understanding of PHP operations. So, here is the basic layout:

The name of the shortcode is generated from within a foreach loop that retrieves the name of custom fields on the post ($keyName).

Code: [Select]
$custom_field_keys = get_post_custom_keys();
foreach ( $custom_field_keys as $key => $keyName )
{
  $valuet = trim($keyName);
  if ( '_' == $valuet{0} )
continue;
if ( get_post_meta($thePostID, $keyName, true) ) :
$fieldName = get_post_meta($thePostID, $keyName, true);
endif;
$fieldValue = $_GET["$keyName"];
add_shortcode((string)$keyName, 'myFields');

}

The add_shortcode function has two parameters ('name_of_shortcode', 'function_name'):

Code: [Select]
add_shortcode((string)$keyName, 'myFields');
I need the myFields function to return the value of $fieldValue from within the foreach loop. That's where the problem lies.
This doesn't work:

Code: [Select]
function myFields()
{
$myString = preg_replace('/[^a-zA-Z\s]/', '', $fieldValue);
return $myString;
}

This does work:
Code: [Select]
function myFields()
{
return 'Content to replace the shortcode';
}


This code will replace [shortcode] with "Content to replace the shortcode" in the post.

The ultimate goal is: when [$keyName] appears anywhere within the post, it will display the content returned by the myFields function ($fieldValue). However, it's not working.  I can't seem to pass the value of $fieldValue to the myFields function and thereby return it to add_shortcode. Any help is appreciated and I am awaiting anxiously to answer any questions.

Here's all the code together:

Code: [Select]
function myFields()
{
$myString = preg_replace('/[^a-zA-Z\s]/', '', $fieldValue);
return $myString;
}

                $custom_field_keys = get_post_custom_keys();

foreach ( $custom_field_keys as $key => $keyName )
{
  $valuet = trim($keyName);
  if ( '_' == $valuet{0} )
continue;
if ( get_post_meta($thePostID, $keyName, true) ) :
$fieldName = get_post_meta($thePostID, $keyName, true);
endif;
$fieldValue = $_GET["$keyName"];
add_shortcode((string)$keyName, 'yourFunction');

}

I can call the following function successfully as a single php program

  // Acknowledge and clear the orders
   function ack($client, $merchant, $id) {
         $docs = array('string' => $id);
         $params = array('merchant' => $merchant, 'documentIdentifierArray' => $docs);
         $result = $client->call('postDocumentDownloadAck', $params);
         return $result;
         }
with

   $result = ack($t, $merchant,'2779540483');

successful output

    [documentDownloadAckProcessingStatus] => _SUCCESSFUL_
    [documentID] => 2779540483

I'm trying to figure out how to call this function as an object from another program.

Trying the following gives error  ***Call to a member function call() on a non-object***

  function postDocumentDownloadAck($t, $merchant, $id) {
     $this->error = null;
     $docs = array('string' => $this->id);
     $params = array('merchant' => $this->merchant, 'documentIdentifierArray' => $docs);

 **  I've tried the following which does nothing
     $result = $this->soap->call('postDocumentDownloadAck', $params);

** I've tried the following   -  which gives error "Call to a member function call() on a non-object"
     $result = $this->t->soap->call('postDocumentDownloadAck', $params);

     if($this->soap->fault) {
        $this->error = $result;
        return false;
     }

     return $result;
  }


***

calling program snippet for above function
   $merchant= array( "merchant"=> $merchantid, "merchantName" => $merchantname, "email"=> $login, "password"=> $password);
   $t = new AmazonMerchantAPI($merchantid, $merchantname, $login, $password);
   $documentlist= $t->GetAllPendingDocumentInfo('_GET_ORDERS_DATA_');
   $docid = $documentlist['MerchantDocumentInfo'][$i]['documentID'];
   $docs = array('string' => $docid);
   $ackorders = $t->postDocumentDownloadAck($t, $merchant,$docs);

Any ideas of what I'm doing wrong are greatly appreciated.

how would i display image without using foreach in this case ?

<?php foreach($images as $image): ?>
<div class="thumb">
<img src="<?php echo $image['url']; ?>">" />
<img src="<?php echo $image['thumb_url']; ?>" />
<?php endforeach;  ?>

Hi all, I want to call a javascript function from a php function like this:

        public function Buscar()
        {
            $HoraInicio = $_POST['edtHoraInicio'];
            $HoraFin = $_POST['edtHoraFin'];
            $FechaInicio = $_POST['edtFec1'];
            $FechaFin = $_POST['edtFec2'];

            $FechaMax = $FechaFin." ".$HoraFin.":00";
            $FechaMin = $FechaInicio." ".$HoraInicio.":00";

            $_GET["FechaMax"] = $FechaMax;
            $_GET["FechaMin"] = $FechaMin;

            echo $FechaMin;

            echo "<script language=javascript>alert('Hi.')</script>";
           
        }

but the function Buscar never show the alert but shows the $FechaMin
