Question

When getting all values from db table, I get this error on the last result value.

Warning: mssql_result() function.mssql-result:
  Bad row offset (32) in C:\ms4w\Apache\htdocs\mapserver\data\.... on line 38

Line 38:

$str  = "MyMap_".mb_convert_encoding(mssql_result($result_set, $row, 0),"UTF-8","SJIS")."_".mb_convert_encoding(mssql_result($result_set, $row, 1),"UTF-8","SJIS");

AND my settings($sql, $con):

$con = mssql_connect ("myServer", "myUsername", "myPassword");
$sql = "SELECT * FROM m_group_layer WHERE group_id=\"".$_SESSION["group_id"]."\" ORDER BY display_order";
$rs_group_layer = mssql_query ($sql, $con);
$group_layer_row = mssql_num_rows($rs_group_layer);

/* EDIT:

Function:

function getLayer($result_set, $row){
    $str  = "MyMap_".mb_convert_encoding(mssql_result($result_set, $row, 0),"UTF-8","SJIS")."_".mb_convert_encoding(mssql_result($result_set, $row, 1),"UTF-8","SJIS");
    return "var ".$str.";\n\n";
}

Loop:

for($i=0; $i<=$group_layer_row; $i++){
    echo getLayer($rs_group_layer, $i);
}

*/

Honestly I am not exactly sure what this error this. So if I could get some suggestions first about what typically causes this error, if there is other code that may be responsible I will post as needed.

Thanks for your help.

Answer 1

Check your main loop, the index variable must start with 0, so if you has 3 lines returning, the last index must be 2.

EDIT:
Change to for($i=0; $i<$group_layer_row; $i++){, without =, it’s a common mistake
