Not sure about this but if I get a variable called $category from _post and use it in the $g select_command the sql produced looks correct and works ok in a MYSQL window but does not produce any values when i use it in a select_command query on my grid.
The $category is a varchar variable.
if (!empty($_POST["Category"]))
$_SESSION["Category"] = $_POST['Category'];
$category = $_SESSION['Category'];
$no = $_REQUEST["rowid"] ;
$g select_command = "SELECT l.`No`,l.`Category`, l.`lens` FROM `Lens` i INNER JOIN `lines` l ON i.No = l.`No` WHERE i.`No` = " .$no . " and i.`Category` = '" . $category . "'";

Hello,
Please send me the code for review (both main-sub grid).
Difficult to say by just this input as this looks fine.

subgrid code is
<?php
error_reporting(E_ALL & ~E_NOTICE);
$conn = mysql_connect("localhost", "root", "root");
mysql_select_db("discount");
if (!isset($_POST['No'])) {
$_SESSION['No'] =($_POST['No']);
$l_No = $_SESSION['No'];;
}
if (!empty($_POST['Category']))
{
$_SESSION['Category'] = $_POST['Category'];
}
$Category = $_SESSION['Category'];
$col = array();
$col["title"] = "No"; // caption of column
$col["name"] = "No"; // field name, must be exactly same as with SQL prefix or db field
$col["width"] = "10";
$cols[] = $col;
$col = array();
$col["title"] = "lens";
$col["name"] = "lens";
$col["width"] = "10";
$cols[] = $col;
$col = array();
$col["title"] = "Category";
$col["name"] = "Category";
$col["width"] = "10";
$cols[] = $col;
$g = new jqgrid();
$grid["sortorder"] = "desc"; // ASC or DESC
$grid["height"] = ""; // autofit height of subgrid
$grid["caption"] = "Invoice Data"; // caption of grid
$grid["autowidth"] = true; // expand grid to screen width
$grid["multiselect"] = true; // allow you to multi-select through checkboxes
$grid["export"] = array("filename"=>"my-file", "sheetname"=>"test"); // export to excel parameters
$grid["subGrid"] = true;
$grid["subgridurl"] = "subgrid_sub_detail.php";
$g->set_options($grid);
$g->set_actions(array(
"add"=>true, // allow/disallow add
"edit"=>true, // allow/disallow edit
"delete"=>true, // allow/disallow delete
"rowactions"=>true, // show/hide row wise edit/del/save option
"export"=>true, // show/hide export to excel option
"autofilter" => true, // show/hide autofilter for search
"search" => "advance" // show single/multi field search condition (e.g. simple or advance)
)
);
if (!empty($_POST["Category"]))
$_SESSION["Category"] = $_POST['Category'];
$category = $_SESSION['Category'];
$no = $_REQUEST["rowid"] ;
$g->select_command = "SELECT l.`No`,l.`Category`, l.`lens` FROM `Lens` i INNER JOIN `lines` l ON i.No = l.`No` WHERE i.`No` = " .$no . " and i.`Category` = '" . $category . "'";
$sql = "SELECT l.`No`,l.`Category`, l.`lens` FROM `Lens` i INNER JOIN `lines` l ON i.No = l.`No` WHERE i.`No` = " .$no . " and i.`Category` = '" . $category . "'";
$g->table = "lines";
$g->set_columns($cols);
$out = $g->render("sub1");
echo $out;
echo "No is: " . $no . " Number is: " . $l_no . " Category is : " . $category . " " . $sql;
?>
subgrid detail is
<?php

mysql_select_db("discount");
include("lib/inc/jqgrid_dist.php");

$grid->set_options($opt);
$grid->table = "Lens";
$grid->select_command = "select No, Category , Lens, Old, New from Lens where Category = 'st'";
$outst = $grid->render("list1");
$grid = new jqgrid();
$opt["caption"] = "RX";
$opt["subGrid"] = true;

it is now wierder.
I know the SQL code is ok as if i hard code the values in the select_command it works ok.
$g->select_command = "SELECT l.`No`,l.`Category`, l.`lens` FROM `Lens` i INNER JOIN `lines` l ON i.No = l.`No` WHERE i.`No` = '1' and i.`Category` = '" . $category . 'st'";
If i try to get the values as below it does not work.
if (!empty($_POST['Category']))
{
$_SESSION['Category'] = $_POST['Category'];
$category = $_SESSION['Category'];
}
$no = $_REQUEST["rowid"] ;
$g->select_command = "SELECT l.`No`,l.`Category`, l.`lens` FROM `Lens` i INNER JOIN `lines` l ON i.No = l.`No` WHERE i.`No` = '1' and i.`Category` = '" . $category . "'";
I am not sure and am slowly going mad.

Hello Joe,
I'm sorry to hear that it's not resolved yet.
Can you email me code files along with sample db dump, so that i can generate the case.
You can email me at [email protected].

There is some kind of bug when using POST variables within a query string. I'm not sure how to get around it quite yet. I've come across this a few times.
