Answer 1

sorry i think my code is a bit confusing
my actual code looks like this
<div class="top_model">
<h1>Model Ratings</h1>
<?php
if(!empty($_SESSION['error_msg'])){?>
<div style="text-align: center"><?php echo $_SESSION['error_msg'];?></div>
<?
session_unset($_SESSION['error_msg']);
}
?>
<ul class="homemodel_thumbs">
<div style="text-align: right">
</div>
<?php
if(!empty($ratingArr)){
foreach($ratingArr as $ratings){
?>
<li><img src="<?php echo base_url();?>images/gallery/large/<?php echo $ratings['gallery_image'];?>" alt="<?php echo $ratings['gallery_image'];?>" class="center_image"/>
<p> </p>
<?php
if(!empty($_SESSION['rate_msg'])){
echo $_SESSION['rate_msg'];
//session_unset($_SESSION['rate_msg']);
}
?>
<form name="rating_form" action="" method="post">
<input type="hidden" name="g_id" value="<?php echo $ratings['gallery_id'];?>"/>
<input type="hidden" name="g_image" value="<?php echo $ratings['gallery_image'];?>"/>
<div style="text-align: center">
<input type="radio" name="rating" value="Hot" onclick="document.rating_form.submit();">Hot</input>
<input type="radio" name="rating" value="Not" onclick="document.rating_form.submit();">Not</input>
</div>
</form>
</li>
<?php
}
}
?>
</ul>

Answer 3

You're unsetting your rating message after you display it:
session_unset($_SESSION['rate_msg']);
This means it's not available after you've posted back the form unless you re-populate it again.
Remove this and i suspect it'll work.

Answer 4

You have an excess ?> :
<?php
if(!empty($_SESSION['error_msg'])){?>
<div style="text-align: center"><?php echo $_SESSION['error_msg'];?></div>
<?
session_unset($_SESSION['error_msg']);
}
if(!empty($_SESSION['rate_msg']))
{
echo $_SESSION['rate_msg'];
session_unset($_SESSION['rate_msg']);
}
?>

Answer 5

You don't open php tag for last statement, (or unnesesery close it) it's treated as html
<?php
if(!empty($_SESSION['error_msg'])){?>
<div style="text-align: center"><?php echo $_SESSION['error_msg'];?></div>
<?php
session_unset($_SESSION['error_msg']);
}
?>
if(!empty($_SESSION['rate_msg'])){
echo $_SESSION['rate_msg'];
session_unset($_SESSION['rate_msg']);
}
?>
EDIT
<?php
// < HERE IS PHP >
if(!empty($_SESSION['error_msg'])){?>
<div style="text-align: center"><?php echo $_SESSION['error_msg'];?></div>
<!-- HERE IS HTML -->
<?
// < HERE IS PHP >
session_unset($_SESSION['error_msg']);
}
?> <!-- CLOSED PHP - NOW IT'S HTML - YOU SHOULD REMOVE IT -->
<!-- THIS IS NOT EXECUTED - BECAUSE IT'S HTML NOW -->
if(!empty($_SESSION['rate_msg'])){
echo $_SESSION['rate_msg'];
session_unset($_SESSION['rate_msg']);
}
?> <!-- THIS IS NOT PHP TAG BECASUE THERE IS NOT OPEN TAG -->
<form name="rating_form" action="" method="post">
<input type="hidden" name="g_id" value="<?php echo $ratings['gallery_id'];?>"/>
<input type="hidden" name="g_image" value="<?php echo $ratings['gallery_image'];?>"/>
<div style="text-align: center">
<input type="radio" name="rating" value="Hot" onclick="document.rating_form.submit();">Hot</input>
<input type="radio" name="rating" value="Not" onclick="document.rating_form.submit();">Not</input>
</div>
</form>
