Read only fields

Thu, 16 Sep 2010 23:59:45 +0000

Sometimes we don’t want certain fields to be editable, then we can use set_col_readonly() method.

Note that you can set more than one columns to be read only using this method.

use phpCtrl\C_DataGrid;
require_once("/file/path/to/conf.php");

$dg = new C_DataGrid("SELECT * FROM Orders", "orderNumber", "Orders");

// change column titles
$dg -> set_col_title("orderNumber", "Order No.");
$dg -> set_col_title("orderDate", "Order Date");
$dg -> set_col_title("shippedDate", "Shipped Date");
$dg -> set_col_title("customerNumber", "Customer No.");

// enable edit
$dg ->enable_edit("INLINE", "CRUD");

// hide a column
$dg -> set_col_hidden("requiredDate");

// read only columns, one or more columns delimited by comma
$dg -> set_col_readonly("orderDate, customerNumber");

$dg -> display();

To allow add for read-only field when adding new records, use “jqGridAddEditAfterShowForm” event, and conditionally remove the “disabled” attribute based on operand, which is either “edit” or “add”.

$dg -> add_event('jqGridAddEditAfterShowForm',
'function(e, form, oper){
if (oper == "add") {
$("#COLUMN_NAME").removeAttr("disabled");
}
}');

Click on row to see the fields that are set to read-only.
