我有一张表,其中的详细信息是从数据库中获取的。
if(mysql_num_rows($sql) > 0)
{
$row_count_n=1;
while($rows=mysql_fetch_assoc($sql))
{
extract($rows);
$options1 = select_data_as_options("project_resources", "name", $resource_allocated);
$options2 = select_data_as_options("project_roles", "name", $role);
echo "<tr>";
echo "<td><select name='ra_$row_count_n'><option value=''>-- Select --$options1</option></select></td>";
echo "<td><select name='role_$row_count_n'><option value=''>-- Select --$options2</option></select></td>";
echo "<td><input type='text' name='start_date_tentative_$row_count_n' class='date_one' value=$tentatively_starts_on /></td>";
echo "</tr>";
$row_count_n++;
}
}
我想在需要时更新表格,我正在使用 Ajax 执行此操作,方法是使用 Jquery 从表单中收集数据并将其保存在按钮单击时。
$("#save_changes_id").click(function()
{
// To retrieve the current TAB and assign it to a variable ...
var curTab = $('.ui-tabs-active'); // in NEWER jQueryUI, this is now ui-tabs-active
var curTabPanelId = curTab.find("a").attr("href");
if(curTabPanelId == "#tab_dia")
{
var curTab = $('#sub_tabs .ui-tabs-active');
var curTabPanelId = curTab.find("a").attr("href");
}
responseData = doAjaxCall($(curTabPanelId + " form"));
if(responseData == 1)
showMessage('status_msg', 'Project details updated successfully', 'green');
else
showMessage('status_msg', 'Error: Please check all the fields', 'red');
});
function doAjaxCall(objForm)
{
var values = objForm.serialize();
$.ajax({
url: ajaxURL,
type: "post",
data: values,
async: false,
success: function(data)
{
responseData = data;
},
error:function()
{
alert('Connection error. Please contact administrator. Thanks.');
}
});
return responseData;
}
Ajax 代码如下:
case "allocate_ba_details":
for($i=1; $i<=$row_count; $i++)
{
$resource = $_REQUEST["ra_$i"];
$role = $_REQUEST["role_$i"];
$start_date_tentative = $_REQUEST["start_date_tentative_$i"];
$already_available_check = mysql_num_rows(mysql_query("select * from project_allocate_ba where project_id = $pdid"));
if($already_available_check > 0)
{
$sql = ("UPDATE project_allocate_ba SET resource_allocated='$resource', role='$role', tentatively_starts_on='$start_date_tentative' WHERE project_id=$pdid");
}
}
echo $sql;
break;
由于我是新手,因此不确定如何传递行名以更新特定行。请提出解决方案。提前致谢。
