Codeigniter CRUD issue

[Jakebert]

Here's my problem, I hope someone can help me see the error!

 

When I go to edit a student, the information comes up in the form fine. When I try to submit the form I get three PHP Notices:

 

A PHP Error was encountered

Severity: Warning

Message: Missing argument 1 for Students::edit()

Filename: admin/students.php

Line Number: 72

 

A PHP Error was encountered

Severity: Notice

Message: Undefined variable: sid

Filename: admin/students.php

Line Number: 94

 

A PHP Error was encountered

Severity: Notice

Message: Undefined variable: sid

Filename: admin/students.php

Line Number: 97

 

Those are all in the controller. Here is the relevant code (sorry that there's so much )

 

This is the index page (controller):

function manage()
{
	$data = $this->students->students(); // List the students
	$this->table->set_heading('ID', 'First', 'Last', 'Age', 'Gender', 'Level'); //Setting headings for the table

	foreach($data as $value => $key)
	{
		//Build action links
		$actions = anchor("admin/students/edit/".$key['sid']."/", "Edit") . anchor("admin/students/delete/".$key['sid']."/", "Delete");
		//Adding row to table
		$this->table->add_row($key['sid'], $key['fname'], $key['lname'], $key['age'], $key['gender'], $key['level'], $actions);
	}

	$this->auth->view('students/manage'); // Load the view
}

 

Here's the edit controller (in students):

	function edit($sid)
{	
	$this->form_validation->set_rules('fname', 'First Name', 'trim|required');
	$this->form_validation->set_rules('lname', 'Last Name', 'trim|required');
	$this->form_validation->set_rules('age', 'Age', 'trim|required|numeric');
	$this->form_validation->set_rules('gender', 'Gender', 'required');
	$this->form_validation->set_rules('level', 'Level', 'trim|required');

	if($this->form_validation->run() == FALSE)
	{
		$data = $this->students->fetch($sid);

		$this->auth->view('students/edit', $data[0]);
	}
	else
	{
		$data['fname'] = set_value('fname');
		$data['lname'] = set_value('lname');
		$data['age'] = set_value('age');
		$data['gender'] = set_value('gender');
		$data['level'] = set_value('level');

		if ($this->students->edit($sid, $data)==1)
		{$this->auth->view('students/edit_success');}

		if($this->students->edit($sid,$data)==0)
		{echo 'There was an error with the update process. Sorry!';}

 

and the data model:

function fetch($sid)
{
	$query = $this->db->get_where('students', array('sid' => $sid));
	return $query->result_array();
}

function edit($sid, $data)
	{
		$this->db->where('sid', $sid);
		$this->db->update('students', $data);
		return $this->db->affected_rows();
	}

 

and FINALLY the edit view:

<fieldset>
<legend>Personal Information</legend>
<?php
echo form_open('admin/students/edit');
?>
First Name: <?php echo form_input('fname', set_value('fname', $fname)); ?>
    Last Name: <?php echo form_input('lname', set_value('lname', $lname)); ?>
<?php echo form_error('fname'); 
echo form_error('lname'); ?>
<br /><br />Age: <?php echo form_input('age', set_value('age', $age)); ?>
<?php echo form_error('age'); ?>
<br />

<br />
Gender:
<?php echo form_radio('gender', set_value('male', 'Male')); ?> Male
<?php echo form_radio('gender', set_value('female', 'Female')); ?> Female

<?php echo form_error('gender'); ?>
</fieldset>

<fieldset>
<legend>Swimming Information</legend>
Level: <?php echo form_input('level', set_value('level', $level));
echo form_error('level'); ?>
</fieldset>

<?php echo form_submit('submit', 'Edit Student'); 
echo form_close(); ?>

 

Thank you for the help!

Your view's  form open URL should contain the $sid after the edit URL segment.
