phpgrid中的滤波值

Question

我使用phpgrid.com的datagrid，并希望通过过滤和只允许某些产品而不是所有产品创建一个名为products的列。现在我可以这么做了吗？

$dg = new C_DataGrid("SELECT kbid,type,issuesummary,productid,priority,createddate,lastupdated,status,resolution,assigneduserid FROM issues", "kbid", "orders");
$dg->set_col_title("kbid", "KBID");
$dg->set_col_width("kbid", 50);
$dg->set_col_title("type", "Type");
$dg->set_col_width("type", 50);
$dg->set_col_title("issuesummary", "Summary");
$dg->set_col_width("issuesummary", 300);
$dg->set_col_title("productid", "Product");
$dg->set_col_width("productid", 70);
$dg->set_col_title("priority", "Priority");
$dg->set_col_width("priority", 70);
$dg->set_col_title("createddate", "Reported");
$dg->set_col_width("createddate", 50);
$dg->set_col_title("lastupdated", "Updated");
$dg->set_col_width("lastupdated", 50);
$dg->set_col_title("status", "Status");
$dg->set_col_width("status", 50);
$dg->set_col_title("resolution", "Resolution");
$dg->set_col_width("resolution", 50);
$dg->set_col_title("assigneduserid", "Assigned");
$dg->set_col_width("assigneduserid", 70);
$dg -> enable_resize(false);
$dg -> set_caption("Issue Base");
$dg->enable_kb_nav(true);
$dg -> enable_search(true);
$dg -> set_dimension(1300, 460);
$dg -> set_col_edittype('status', 'select', 'OP:Open;CL:Closed;DF:Deferred;VE:Vendor;FQ:FAQ');
$dg -> set_col_edittype('type', 'select', 'IP:IP;IT:IT;UP:UP;UQ:UQ;UW:UW;IF:IF;UF:UF;IW:IW;DI:DI');
$dg -> set_col_edittype('priority', 'select', '0:None;1:Urgent;2:High;3:Medium;4:Low;5:Lowest');
$dg -> set_col_edittype('resolution', 'select', 'PP:Pending Review;FX:Fixed;UR:Unreproducable;AD:As Designed;UF:Unable to Fix;WD:Withdrawn;NI:Need More Info;AS:Assigned;WK:Working on Issue;TS:Testing Issue;RJ:Rejected;UF:Temporary Fix;AC:Accepted');
$dg -> set_col_edittype('productid', 'select', '17:ALCS/GI;20:ALCS/ZAS;125:Beta zTPFGI;16:RTF;114:zTPFGI');
$dg -> set_col_edittype('assigneduserid', 'select', $y);
$dg -> set_col_property("lastupdated", array("formatter"=>"date","formatoptions"=>array("srcformat"=>"ISO8601Short","newformat"=>"d-m-Y")));
$dg -> set_col_property("createddate", array("formatter"=>"date","formatoptions"=>array("srcformat"=>"ISO8601Short","newformat"=>"d-m-Y")));
$dg->set_pagesize(30);
$dg->enable_export('EXCEL');
$dg->display(); 

我希望过滤列productid，并且只允许显示值16、17、20、114、125。

Answer 1

首先，我认为第一行是错的。最后一个参数始终是表名，如下所示：

http://phpgrid.com/example/example-1-a-basic-php-datagrid-2/

请注意，第三个参数总是等于数据库表名，而不是别名或任意名称(参见下面)。

正确的一行是：

$dg = new C_DataGrid("SELECT kbid,type,issuesummary,productid,priority,createddate,lastupdated,status,resolution,assigneduserid FROM issues", "kbid", "issues");

现在，回到您的问题，您需要使用set_query_filter来过滤数据。它基本上添加了WHERE sql子句，并在呈现网格之前从数据库中进行筛选。filterwhere/
