Hello,

Alert ('No items selected! And select all items in default! ');
Chk_ SQL _base = 'select * from '+ table_name + 'Where Regression_Id =' + reg_id_base;
Chk_ SQL _cmp = 'select * from '+ table_name + 'Where Regression_Id =' + reg_id_cmp;
}
Else {
Chk_ SQL _base = 'SELECT TestCase, Design_name ,';
Chk_ SQL _cmp = 'SELECT TestCase, Design_name ,';
For (var I = 0; I
 Chk_ SQL _base + = chk_items [I] + ','
Chk_ SQL _cmp + = chk_items [I] + ','
}
Chk_ SQL _base + = chk_items [I] + 'from' + table_name + 'Where Regression_Id = '+ reg_id_base;
Chk_ SQL _cmp + = chk_items [I] + 'from' + table_name + 'Where Regression_Id = '+ reg_id_cmp;

Show_cmp_internal_chk_table.php:

 $csv_data4 = Array();
$sql_chk_cmp  = $_GET["sql_chk_cmp1"];
$sql_chk_base = $_GET["sql_chk_base"];
echo $sql_chk_base."
";
echo $sql_chk_cmp."
";
...

Here, $ SQL _chk_base has data, and $ SQL _chk_cmp is empty in any case. the url information also contains this data. What is this. Such ajax code is also used hundreds of times.

------ Solution --------------------
Is there a space after the url parameter?
