I'm trying to make my sub category looks different when it's selected, for that I've used sub_cat variable in my php. So value of $sub_cat depends on the page that loads. On the top I've this code:
if(!empty($_GET['sub_cat'])){
$sub_cat=$_GET['sub_cat'];
}
else{
$sub_cat=0;
}
Now what my code for displaying list.
<li <?php if($sub_cat==11) echo "style='color:#C00'"; ?> ><a href="vegetables.php?sub_cat=11">Popular</a></li>
<li <?php if($sub_cat==12) echo "style='color:#C00'"; ?> ><a href="vegetables.php?sub_cat=12">Exotic</a></li>
<li <?php if($sub_cat==13) echo "style='color:#C00'"; ?> ><a href="vegetables.php?sub_cat=13">Fibrous Veg</a></li>
But it doesn't seem to make any difference, value of $sub_cat is coming fine as in 11,12,13 but this code is not working. Can anyone spot the minor mistake or major mistake?
How about transferring the style
attribute to the a
element instead of placing it in the li
.
<li><a href="vegetables.php?sub_cat=11" <?php if($sub_cat==11) echo "style='color:#C00'"; ?>>Popular</a></li>
<li><a href="vegetables.php?sub_cat=12" <?php if($sub_cat==12) echo "style='color:#C00'"; ?>>Exotic</a></li>
<li><a href="vegetables.php?sub_cat=13" <?php if($sub_cat==13) echo "style='color:#C00'"; ?>>Fibrous Veg</a></li>
Try this:
if(isset($_GET['sub_cat'])){
$sub_cat=$_GET['sub_cat'];
}
else{
$sub_cat=0;
}
