jqGrid - inline edit can not save result to database after edit
I'm new to use jqGrid and there is a problem when I try to use the inline edit feature. Here is my code: My First Grid
<link rel="stylesheet" type="text/css" media="screen" href="css/ui-lightness/jquery-ui-1.8.16.custom.css" />
<link rel="stylesheet" type="text/css" media="screen" href="css/ui.jqgrid.css" />
<style type="text/css">
html, body {
margin: 0;
padding: 0;
font-size: 75%;
}
</style>
<script src="js/jquery-1.5.2.min.js" type="text/javascript"></script>
<script src="js/i18n/grid.locale-en.js" type="text/javascript"></script>
<script src="js/jquery.jqGrid.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(function(){
var lastsel2
$("#list").jqGrid({
url:'example.php',
datatype: 'xml',
mtype: 'GET',
colNames:['id','name', 'status'],
colModel :[
{name:'id', index:'id', width:55},
{name:'name', index:'name', width:90, editable: true},
{name:'status', index:'status', width:80, align:'right', editable: true},
],
onSelectRow: function(id){
if(appid && appid!==lastsel2){
jQuery('#list').restoreRow(lastsel2);
jQuery('#list').editRow(id,true);
lastsel2=id;
}
},
editurl: "example.php",
pager: '#pager',
rowNum:10,
rowList:[10,20,30],
sortname: 'appid',
sortorder: 'desc',
viewrecords: true,
gridview: true,
caption: 'My first grid'
});
});
</script>
</head>
<body>
<table id="list"><tr><td/></tr></table>
<div id="pager"></div>
</body>
The problem is it could edit the row when I click it, and also can save temporarily after I press the enter. But when I reload the grid, it still shows the previous data before I eidt, which means it doesn't update the database. I wonder why and how to solve it?
Here is the example.php code:
<?php
include("dbconfig.php");
$page = $_GET['page'];
$limit = $_GET['rows'];
$sidx = $_GET['sidx'];
$sord = $_GET['sord'];
if (!$sidx)
$sidx = 1;
$db = mysql_connect("$dbhost", "$dbuser", "$dbpassword") or die("Connection Error: " . mysql_error());
mysql_select_db("$database") or die("Error connecting to db.");
$result = mysql_query("SELECT COUNT(*) AS count FROM app");
$row = mysql_fetch_array($result, MYSQL_ASSOC);
$count = $row['count'];
if ($count > 0 && $limit > 0) {
$total_pages = ceil($count / $limit);
} else {
$total_pages = 0;
}
if ($page > $total_pages)
$page = $total_pages;
$start = $limit * $page - $limit;
if ($start < 0)
$start = 0;
$SQL = "SELECT id, name, status FROM app";
$result = mysql_query($SQL) or die("Couldn't execute query." . mysql_error());
header("Content-type: text/xml;charset=utf-8");
$s = "<?xml version='1.0' encoding='utf-8'?>";
$s .= "<rows>开发者_Go百科;";
$s .= "<page>" . $page . "</page>";
$s .= "<total>" . $total_pages . "</total>";
$s .= "<records>" . $count . "</records>";
// be sure to put text data in CDATA
while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {
$s .= "<row id='" . $row['id'] . "'>";
$s .= "<cell>" . $row['id'] . "</cell>";
$s .= "<cell>" . $row['name'] . "</cell>";
$s .= "<cell>" . $row['status'] . "</cell>";
$s .= "</row>";
}
$s .= "</rows>";
echo $s;
?>
First of all you should change the code
onSelectRow: function(id){
if(appid && appid!==lastsel2){
jQuery('#list').restoreRow(lastsel2);
jQuery('#list').editRow(id,true);
lastsel2=id;
}
}
to something like
onSelectRow: function (id) {
if (id && id !== lastsel2){
jQuery('#list').restoreRow(lastsel2);
jQuery('#list').editRow(id,true);
lastsel2 = id;
}
}
because currently you use undefined appid instead of id.
Moreover you should remove trailing comma at the end of colModel definition: change },] to }] and place semicolon after var lastsel2.
