hi
I am doing web portal design using php.
I gave part of one of my screen coding.
<html>
<head>
<script language = "javascript">
function list_all_click()
{
search_by_index_value = 0;
jb_asc_desc_order = "A";
document.location = "jukeboxes.php?search_by_value="+search_by_index_v alue+"&jb_asc_desc_order_val="+jb_asc_desc_order;
}
</script>
<head>
</html>
<body>
<?php
@extract($_GET);
@extract($_POST);
if($search_by_value == "")
$search_by_value = 0;
if($jb_asc_desc_order_val == "D")
{
$order_by_string1 = "jukeboxes";
$order_by_string2 = "jukebox_serial";
$order = "desc";
}
?>
<table>
<tr>
<td><img src="images/list.jpg" alt="Click to list All Jukebox" width="50" height="13" align="absmiddle" onclick = "list_all_click()"></td>
</tr>
</table>
</body>
The above code is presented in 'jukeboxes.php' file that is variables are passed to the self php page through javascript.
It is working functionwise properly. I am getting expected output in the screen.
But the problem is that the following two warning messages is written in system 'error log' file.
message1:
"
[client 125.17.100.148] PHP Notice: Undefined variable: search_by_value in /var/www/html/dco/jukeboxes.php on line 362, referer: http://125.17.100.148/dco/company.php
"
Where the line 362 is
'if($search_by_value == "")'
message2:
"
[client 125.17.100.148] PHP Notice: Undefined variable: jb_asc_desc_order_val in /var/www/html/dco/jukeboxes.php on line 766, referer: http://125.17.100.148/dco/jukeboxes.php
"
Where the line 766 is
'if($jb_asc_desc_order_val == "D")'
The system has linux operating system.
I need to solve the problem as soon as possible.
Please help me.
Advance thanks.
