PHP MVC not sending value to controller - php

Question

I have been making a MVC site, I am having trouble sending the row id from my form to my controller.
The code that I am using for my form gets the row ID for each db entry and assigns it to a hidden value. When the form is submitted it sends the parameters to the controller (should send $uid) but the uid isn't making it to the controller.
Form Code (buttons.php)
<?php
$itemsDAO = new ItemsDAO();
$result = $itemsDAO->getItems();
foreach ($result as $row) {
$uid = $row['id'];
?>
<form action="index.php" method="post">
<fieldset>
<input id='action' type='hidden' name='action' value='deleteItem' />
<p>
<div class="form-group">
<div class="controls">
<input type="hidden" id="fId" name="fId" value="<?php echo $uid; ?>">
<input type="submit" class="btn btn-success" value="Delete">
</div>
</div>
</p>
</fieldset>
</form>
<?php } ?>
Controller function
function deleteItem($parameters) {
$id=$parameters["fId"];
if ($this->model->deleteItem( $id )) {
$this->model->hasDeleteFailed = false;
$this->model->setDeleteItemConfirmation();
return (true);
}
else
$this->model->deleteItemError ( DELETE_ITEM_ERROR_STR );
}
View.php - where I am showing the list of db items and the buttons.php
$this->model->prepareItemList();
$buttons = file_get_contents( "templates/buttons.php");
$HTMLItemList = "";
foreach ( $this->model->itemList as $row )
$HTMLItemList .= "<li><strong>" . $row ["title"] . ": </strong>" . $row ["price"] . "<blockquote>" .$row ["description"] . " " . $buttons ."</blockquote></li>";

Answer 1

Try $_POST["fld"]; in your controller to get value. If you are using any framework like codeigniter then you can use its own methods.
For example codeigniter has
$this->input->post();

Answer 2

Okay,
step by step the $uid has to first make it into the form elements value attribute. Check the html source code to make sure this is actually happening.
place var_dump($_POST) exit; in your controller to find what is actually being recieved if anything at all.
check to make sure your result array element actual has a value and not an empty string value or NULL.
Hmm S.O. code formatting bad.
// turn on error reporting for dev to view empty or missing variable errors
ini_set('error_reporting', E_ALL);
$result=$itemsDAO->getItems();
foreach ($result as $row) {
($row['id'] != ''? $uid = $row['id'] : $uid ='no id found');
// debug result
echo '<pre>' . print_r($row,1) .'</pre>';
}
