Answer 1

Ihre foreach-Schleife Syntax scheint falsch versuchen, diese stattdessen

<? 
    foreach ($projects as $project) 
    { 
    ?> 
     <li><a href="<?php echo base_url()."index.php/project_list/show_project_id/" . $project->id; ?>"><?php echo $project->project_name1; ?></a></li> 
<? 
} 
?> 
     </ol> 
     </div> 
     <div id="detail"> 
     <!-- Fetching All Details of Selected Student From Database And Showing In a Form --> 
     <?php foreach ($single_project as $project){ ?> 

     <form method="post" action="<?php echo base_url() . "index.php/update_ctrl/update_project_id1"?>"> 
     <label id="hide">Id :</label> 
     <?php echo $project->project_name1; ?> 
     <label>Name :</label> 
     <input type="text" name="dname" value="<?php echo $project->location; ?>"> 
     <label>Email :</label> 
     <input type="text" name="demail" value="<?php echo $project->start_date; ?>"> 
     <label>Mobile :</label> 
     <input type="text" name="dmobile" value="<?php echo $project->end_date; ?>"> 
     <label>Address :</label> 
     <input type="text" name="dmobile" value="<?php // echo $project->firstname1; ?>"> 
     <input type="text" name="daddress" value="<?php // echo $project->project_address; ?>"> 
     <input type="submit" id="submit" name="dsubmit" value="Update"> 
     </form> 
     <? 
     } 

     ?> 
     </div>
