multidimensional array in view in codeigniter

Question

I have the following array from my model, here the var_dump:

array(4) {
[0]=>
 array(1) {
   [0]=>
   array(5) {
 ["payment_student"]=>
 string(4) "2406"
 ["fee_month"]=>
 string(10) "2018-02-00"
 ["arrears"]=>
 string(1) "0"
 ["payment_description"]=>
 string(17) "Transport, 120 , "
 ["payment_amount"]=>
 string(3) "120"
   }
 }
 [1]=>
 array(1) {
   [0]=>
   array(5) {
     ["payment_student"]=>
 string(4) "2415"
 ["fee_month"]=>
 string(10) "2018-02-00"
 ["arrears"]=>
 string(1) "0"
 ["payment_description"]=>
 string(33) "Transport, 1500 , Tuition, 620 , "
 ["payment_amount"]=>
 string(4) "2120"
   }
     }
 [2]=>
     array(1) {
   [0]=>
   array(5) {
     ["payment_student"]=>
 string(4) "2175"
 ["fee_month"]=>
 string(10) "2018-02-00"
 ["arrears"]=>
 string(1) "0"
 ["payment_description"]=>
 string(17) "Transport, 620 , "
 ["payment_amount"]=>
 string(3) "620"
   }
 }
 [3]=>
 array(1) {
   [0]=>
   array(5) {
 ["payment_student"]=>
 string(4) "2087"
 ["fee_month"]=>
 string(10) "2018-02-00"
 ["arrears"]=>
 string(1) "0"
 ["payment_description"]=>
 string(33) "Transport, 1500 , Tuition, 420 , "
 ["payment_amount"]=>
 string(4) "1920"
   }
 }
}

here my view for loop:

$i=0;
foreach ($payments_view as $key => $data) { 

            ?>
                <td><?php echo $i; ?></td>
                <td><?php echo $data[$i]['payment_student']?></td>
                <td><?php echo $data[$i]['arrears']?></td>

                <td><?php echo $data[$i]['payment_description']; ?></td>
                <td><?php echo $data[$i]['payment_amount']+$data[$i]['arrears']; ?></td>
                <td></td>
                <td></td>
                <td></td>
            </tr>
            <?php
                $i++;
 } 

It display the 1st row, but for next rows give following error:

A PHP Error was encountered Severity: Notice Message: Undefined offset: 1 Filename: views/fee_register_list.php Line Number: 95 Backtrace: File: C:\\xampp\\htdocs\\learn_ci\\ksi_gentelella\\application\\views\\fee_register_list.php Line: 95 Function: _error_handler File: C:\\xampp\\htdocs\\learn_ci\\ksi_gentelella\\application\\controllers\\Fee_Controller.php Line: 173 Function: view File: C:\\xampp\\htdocs\\learn_ci\\ksi_gentelella\\index.php Line: 315 Function: require_once

How can I make my array simple one array so, can be able to use it. in such a shape I think its very complex.

Answer 1

Try this :

for($i=0;$i<count($data);$i++){
   <tr>
   $firstObj=$data[i][0];
    for($j=0;$j<5;$j++){
       <td><?php echo $i; ?></td>
       <td><?php echo $firstObj[$j]['payment_student']?></td>
       <td><?php echo $firstObj[$j]['arrears']?></td>
       <td><?php echo $firstObj[$j]['payment_description']; ?></td>
       <td><?php echo $firstObj[$j]['payment_amount']." ".$firstObj[$j]['arrears']; ?></td>
    }
   </tr>
}

Answer 2

You can use array_column to "flatten" your array:

<?php foreach (array_column($payments_view, 0) as $i => $data) { ?>
    <tr>
        <td><?= $i; ?></td>
        <td><?= $data['payment_student']?></td>
        <td><?= $data['arrears']?></td>
        <td><?= $data['payment_description']; ?></td>
        <td><?= $data['payment_amount'] + $data['arrears']; ?></td>
        <td></td>
        <td></td>
        <td></td>
    </tr>
<?php } ?>

Although it should not be done in view. Try to refactor your code, so your view would have data in proper format.
