Detect how many array exist?

Question

I am using CodeIgniter framework. I am sending an array to my view, but I could not get the array in my view.

This is my controller code:

public function edit($id)
{
    $record = $this->Start_model->get_entry($id);//receiving array from model 
    $this->load->view('edit',$record);//send array to my view
}

This is my array on controller that I send:

Array
(
    [0] => Array
        ( [id] => 1 [name] => Hamza [age] => 20 [address] => audit and account [phone] => 03000000000  )
)

But when I call this array view I get this error:

Undefined variable: record

This is how I am getting my array in view:

<?php 
echo '<pre>';
print_r($record); 
echo '</pre>';
?>

Now I know I am sending an array to my view but I want to know If there is array in my view or not. I can get record through another method but I think it is not a good practice. So anyone can help me how I can detect if there is an array in my view?

My question is about detect array in my view. I want to know how array is coming to my view. as I can also debugging It. — xitas

@TheRealHamza wait, are you referring to something like the global parent array that holds the data inside the view when its imported from controller? i dont think you can check since i think extract() has been used — Kevin

In your controller, send a parent array instead:

public function edit($id)
{
    $data = array();
    $data['record'] = $this->Start_model->get_entry($id); // provided this is not empty
    $this->load->view('edit', $data);
}

Then in your view:

foreach($record[0] as $key => $value) {
    echo $value['id'];
    // the rest blah blah
}

Codeigniter extracts the array passed to a view, creating variables based on the keys of the array. To work as you want, pass an array with a key or record and a value of your array:

public function edit($id)
{
    $data = array('record' => $this->Start_model->get_entry($id));
    $this->load->view('edit',$data);//send array to my view
}

Then this will work in your view:

<?php 
echo '<pre>';
print_r($record); 
echo '</pre>';
?>

The way you are currently sending the data, it will be extracted into individual variables for each element in the array, however as your array is numerically indexed, and php variable name rules prevent numeric variable names, you cannot access the data.

Thanks @Steve but can you tell me how I can see the existing array in my view?

Steve Over a year ago

@TheRealHamza However, if you make this small change, you can access the array as you expected to - via the variable $record

Your answer is nearly right but I want to confirm I can't detect how many array exist in php?

Steve Over a year ago

@TheRealHamza Yes, i can confirm that with your current code, as shown in your question, you cannot access the data in $record inside your view, so you cannot count the number or records or do anything else with it.

@TheRealHamza Oops, real simply typo, please see edit (replaced , with =>)
