Help with Warning Message implode()

[Guest]

I have recently added a Back Button function to my website and i have noticed that on certain occasions the following message is displayed in my product_info page above my new Back Button,

 

Warning: implode() [function.implode]: Invalid arguments passed in /home/ds1602/public_html/catalog/includes/functions/general.php on line 239

 

The message only seems to be displayed when the user enters the screen via the Manufacturer search route, all other routes into the product_info page the message is not displayed and all is fine, I have done some investigation and it seems to be related to the variable current_category_id not being set, can anyone shed some light on this particular problem?

 

I've added the code from product_info with refrence to the code added for the new Back Button coding,

 

<tr>

<td><table border="0" width="100%" cellspacing="1" cellpadding="2" class="blankBox">

<tr class="infoBoxContents">

<td><table border="0" width="100%" cellspacing="0" cellpadding="2">

<tr>

<td width="10"><?php echo tep_draw_separator('pixel_trans.gif', '10', '1'); ?></td>

<td class="main" align="left"><?php echo '<a href="' .tep_href_link(FILENAME_DEFAULT, tep_get_path($current_category_id = '')) . '">'. tep_image_button('button_back.gif', IMAGE_BUTTON_BACK) . '</a>'; ?></td>

</tr>

</table></td>

</tr>

</table></td>

</tr>

Well because the file hasn't been accessed via a category $cPath_array has not been set. $current_category_id is also manually hardcoded to "" via your code.

 

Perhaps try the following: -

 

<tr>
 <td>
<table border="0" width="100%" cellspacing="1" cellpadding="2" class="blankBox">
  <tr class="infoBoxContents">
	<td>
	  <table border="0" width="100%" cellspacing="0" cellpadding="2">
		<tr>
		  <td width="10"><?php echo tep_draw_separator('pixel_trans.gif', '10', '1'); ?></td>
		  <?php 
		  if( isset($cPath_array) && is_array($cPath_array) ){
			echo '			  <td class="main" align="left"><a href="' . tep_href_link(FILENAME_DEFAULT, tep_get_path($current_category_id = '')) . '">'. tep_image_button('button_back.gif', IMAGE_BUTTON_BACK) . '</a></td>' . "\n";
		  } else {
			echo '			  <td class="main" align="left"><a href="' . tep_href_link(FILENAME_DEFAULT) . '">'. tep_image_button('button_back.gif', IMAGE_BUTTON_BACK) . '</a></td>' . "\n";
		  }
		  ?>
		</tr>
	  </table>
	</td>
  </tr>
</table>
 </td>
</tr>
