Just to make it fast, here are some of my shortened codes:
Controllers:
public function edit() // assign positions to array $data["position"]
{
$data["position"] = $this->My_Model->get_query_array("SELECT * FROM Position_List");
}
public function update() // after submission, call this method
{
echo $getdata['Position_Code'] = $_POST['position'];
// returns error (undefined index), no result for position
}
Model:
public function get_query_array($query_statement) // my query
{
$query = $this->db->query($query_statement);
return $query->result();
}
View
<label for="position">Change Position</label>
<select name="position" id="position" >
<option value=""></option>
<?php
foreach($position as $row)
{
echo "<option value='".$row->Position_Code."'".($row->Position_Code==$Default_Position?"selected='selected'":"").">".$row->Position_Name."</option>";
}
?>
</select>
For clearer explanation of my problem:
1. controller: edit() method works fine - check
2. model: get_query_array() returns the query result - check
3. view: the foreach loop returns all the positions I queried - check
4. controller: update() method returns this error upon submission: - ERROR!
A PHP Error was encountered
Severity: Notice
Message: Undefined index: position
Filename: controllers/Home.php
How come it says undefined index although the loop displays the positions and name="position" id="position" are present from the view.
I already tried using var_dump($position) and print_r($position) and it returns all the positions from the database without any NULL values.
Please help. Thanks!
