You are going to need to give more information, you provided a line of code that has a custom function, yet don't give the code for the function, instead give a link to a page has over 25 sections of tutorial, which most people are not going to want to read through them all to find the code you are working with.

sorry :oops:

adding category image:

Code: Select all

<?php 
if (!defined('WEB_ROOT')) { 
    exit; 
} 


$parentId = (isset($_GET['parentId']) && $_GET['parentId'] > 0) ? $_GET['parentId'] : 0; 
?>  

<form action="processCategory.php?action=add" method="post" enctype="multipart/form-data" name="frmCategory" id="frmCategory"> 
 <p align="center" class="formTitle">Add Category</p> 
  
 <table width="100%" border="0" align="center" cellpadding="5" cellspacing="1" class="entryTable"> 
  <tr>  
   <td width="150" class="label">Category Name</td> 
   <td class="content"> <input name="txtName" type="text" class="box" id="txtName" size="30" maxlength="50"></td> 
  </tr> 
  <tr>  
   <td width="150" class="label">Description</td> 
   <td class="content"> <textarea name="mtxDescription" cols="50" rows="4" class="box" id="mtxDescription"></textarea></td> 
  </tr> 
  <tr>  
   <td width="150" class="label">Image</td> 
   <td class="content"> <input name="fleImage" type="file" id="fleImage" class="box">  
    <input name="hidParentId" type="hidden" id="hidParentId" value="<?php echo $parentId; ?>"></td> 
  </tr> 
 </table> 
 <p align="center">  
  <input name="btnAddCategory" type="button" id="btnAddCategory" value="Add Category" onClick="checkCategoryForm();" class="box"> 
  &nbsp;&nbsp;<input name="btnCancel" type="button" id="btnCancel" value="Cancel" onClick="window.location.href='index.php?catId=<?php echo $parentId; ?>';" class="box">
