I try to write a site with CodeIgniter but I’ve a problem with PHP. I’m sure that it’s so simple and can’t be wrong. But I don’t know bugs from , just a newbie of CodeIgniter 🙂

    <html>  
    <head>  
        <title><?=$page_title?></title>  
    </head>  
    <body>  
        <?php foreach($result as $row):?>  
        <h3><? echo $row->title; ?></h3>  
        <p><? echo $row->text; ?></p>  
        <?php endforeach;?>  
    </body>  
</html>

    The variable you supply to the foreach loop has to be an array. You can skip the foreach if the value of the variable supplied is not an array with the solution below.

    <?php if(is_array($result)): ?>
<?php foreach($result as $row):?>  
<h3><? echo $row->title; ?></h3>  
<p><? echo $row->text; ?></p>  
<?php endforeach;?>  
<?php endif; ?>
