Hi guys
I've been following the file upload tutorial as closely as possible and trying to relate it to my own controller but when I try to upload an image it throws back the default error message instead of displaying it on the same screen.
Here is my code so far:
Homeprofile view:
<div id="maincontent">
<div id="primary">
<?$image;?>
<?=form_open_multipart('homeprofile/do_upload');?>
<input type="file" name="userfile" size="20" />
<?=form_submit('submit', 'homeprofile')?>
<?=form_close();?>
</div>
<div id="secondary">
<p>
<?=$profileText;?>
</p>
<p>
<?=form_open('homeprofile/changetext'); ?>
<?php $msgbox = array(
'name' => 'profiletext',
'rows' => '8',
'cols' => '30',
);?>
<?=form_textarea($msgbox);?>
</p>
<p>
<?=form_submit('submit', 'Change'); ?>
<?=form_close(); ?>
</p>
</div>
</div>
upload_form.php which throws the error back on the same view above:
<html>
<head>
<title>Upload Form</title>
</head>
<body>
<?php echo $error;?>
</body>
</html>
page which is meant to display image in homeprofile view:
<html>
<head>
<title>Upload Form</title>
</head>
<body>
<h3>Your file was successfully uploaded!</h3>
<ul>
<?php foreach ($upload_data as $image => $value):?>
<li><?php echo $image;?>: <?php echo $value;?></li>
<?php endforeach; ?>
</ul>
<p><?php echo anchor('upload', 'Upload Another File!'); ?></p>
</body>
</html>
