How to make connection between controller and view? - php

Question

i have been working on it and didn't get a proper solution.what i want to do is i have a function in controller that gets data from model .
this is my controller function:
function index() {
$data['results1'] = $this->RetrieveData_model->GetData();
$this->load->view('ViewData',$data);
}
i want to access that $data['results1'] variable in my editview to auto fill the fields.this is my view:
<div id="container">
<?php echo form_open('insert_ctrl/updateData/'); ?>
<h1>Update Data Into Database Using CodeIgniter</h1><hr/>
<?php if (isset($message)) { ?>
<CENTER><h3 style="color:green;">Data updated successfully</h3></CENTER><br>
<?php } ?>
<?php echo form_label('Student Name :'); ?> <?php echo form_error('dname'); ?><br />
<?php echo form_input(array('id' => 'dname', 'name' => 'dname', 'value' => $results1[0]->Student_Name)); ?><br />
<?php echo form_label('Student Email :'); ?> <?php echo form_error('demail'); ?><br />
<?php echo form_input(array('id' => 'demail', 'name' => 'demail', 'value' => $results1[0]->Student_Email)); ?><br />
<?php echo form_label('Student Mobile No. :'); ?> <?php echo form_error('dmobile'); ?><br />
<?php echo form_input(array('id' => 'dmobile', 'name' => 'dmobile', 'placeholder' => '10 Digit Mobile No.', 'value' => $results[0]->Student_Mobile)); ?><br />
<?php echo form_label('Student Address :'); ?> <?php echo form_error('daddress'); ?><br />
<?php echo form_input(array('id' => 'daddress', 'name' => 'daddress','value' => $results1[0]->Student_Address)); ?><br />
<?php echo form_hidden( array('id' => 'studentId', 'name' => 'studentId','value' => $results1[0]->Student_id) ); ?><br />
<?php echo form_submit(array('id' => 'submit', 'value' => 'Submit')); ?>
<?php echo form_close(); ?><br/>
<div id="fugo">
</div>
<button type="button" onclick="window.location='<?php echo base_url();?>ViewData_ctrl/index'">
View data Record
</button>
</div>
when i accessed that "result1" in view it is giving error:
A PHP Error was encountered

Answer 1

Try this in your controller you given wrong view name
function index() {
$data['results1'] = $this->RetrieveData_model->GetData();
$this->load->view('EditView',$data);
}
and your view Var_dump your array.
<?php
var_dump($results1);
?>

Answer 2

check your file name
$this->load->view('ViewData',$data);
// change to
$this->load->view('EditView',$data);

Answer 3

there is an other mistake in your editview file:
you have skipped "1" in $results1 array it may help you out
$results1[0]->Student_Mobile;

Answer 4

Try this answer.you wil get the result very easily
in controller
function index() {
$data['results1'] = $this->RetrieveData_model->GetData();
$this->load->view('ViewData',$data);
}
in view page
<?php
foreach($results1 as $row)
{
echo $row->id; //echo your fields like this
}
?>

Answer 5

In view page you can use
<?php echo form_open('insert_ctrl/updateData/'); ?>
<?php
foreach($results1 as $row)
{
//try this to get details
echo $row->Student_Address;
echo $row->Student_id;
//or try this
echo $row['Student_Address'];
echo $row['Student_id'];
}
?>
