Question

Undefined Index in php codeigniter framework view

Asked by: TBSS

Using Codeigniter Framework 1.71. using MVC
Retrieved database entries through controller and Model.

Problem is displaying information through the view (advert.php) page.
gives an undefined index error with E_all. If I suppress the error messages the result is serving a blank page.

Investigating using  <?php  echo print_r($advert);?> gives the expected array dump with correct data.

Attempting to use the array to print the data fields just gives the error.

I am hoping that this is something simple and I have just been hit with the $tupid stick.
Any enlightenment would be appreciated. Thanks






<?php //view page advert.php ?>
 
<div id="advert">
<h2>Advertiser Details</h2>
 
 
<?php echo print_r($advert);
//
//print_r works fine  - displays full contents of $advert array
//
//attempting to use $advert results in undefined index errors
//
?>
 
<?php
  echo "<h2>".$advert['name']."</h2>\n";
  echo "<img src='".$advert['image']."' border='0' align='left'/>\n";
  echo "<p>".$advert['description'] . "<br/>\n";
  echo "<p>".$advert['contact']."<br />\n";
  echo "<br/>";
  echo "<br/>";
 ?>
 
</div>

instead of:
$advert['name']
.$advert['image']

try:
$advert->name
.$advert->'image

Tried your suggestion. The result is the same but the error message is different.

ERROR - 2009-08-24 06:12:18 --> Severity: Notice  --> Trying to get property of non-object J:\thrice\system\application\views\advert.php 19

Thanks for the input - I will keep working on this or a way around it.
There are other parts of the site that I need to finish.
Hopefully, the rest will go better than this portion.

Hello,

I have the same problem. I cannot reference the key-values in the array.

This is the print_r output.

Array
(
    [0] => stdClass Object
        (
            [id] => 1
            [prodname] => Baked Fillo
            [base_unit] => 500.00
            [retail_price] => 50.00
            [alert_quantity] => 0.00
            [ptname_fk] => 1
            [pcname_fk] => 1
            [wname_fk] => 1
            [uname_fk] => 1
            [uname] => grams
            [pcname] => Fillo
            [ptname] => Finished Good
            [wname] => Finished Goods
        )
 
)


When I refer to the variables with $product->id, gives me error Trying to get property of non-object.... And when I use $product['id'], give me Undefined Index.

Thank you!
