我正在使用datatables插件，由此我正在寻找一个名为“特权”的字段。特权值为“superadmin”和“admin”。对于通配符搜索，只要我通过“管理员”进行搜索，管理员和超级管理员都会显示记录。如何解决这个问题。我的代码是这样的：datatables搜索选项
function fnFilterColumn (i)
{
$('#example').dataTable().fnFilter(
$("#col"+(i+1)+"_filter").val(),i,true,false);
}
$(document).ready(function(){
var oTable = $('#example').dataTable({
"bProcessing": true,
"sAjaxSource": "datatabledb.php",
"bJQueryUI": true,
"sPaginationType": "full_numbers",
"sDom": 'T<"clear">lfrtip',
"oTableTools": {
"aButtons": [
{
"sExtends": "csv",
"sButtonText": "Save to CSV"
}
]
},
"oLanguage": {
"sSearch": "Search all columns:"
},
"aoColumns": [
null,
{ "bSortable": false }, // disable the sorting property for checkbox header
null,null,null,null,null,null,null,null
]
});
在datatabledb.php文件，我写下了我的DB代码，如：
<?php
include('library/function.php');
/* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *

*/
/* Array of database columns which should be read and sent back to DataTables. Use a space where
* you want to insert a non-database field (for example a counter or static image)
*/
$aColumns = array('admin_name','admin_photo','username','email','age','location','contact_no','role','creation_date','status');
/* Indexed column (used for fast and accurate table cardinality) */
$sIndexColumn = "admin_id";
/* DB table to use */
$sTable = "admin_details";
/* Database connection information */
$gaSql['user'] = "root";
$gaSql['password'] = "";
$gaSql['db'] = "alert";
$gaSql['server'] = "localhost";
/* REMOVE THIS LINE (it just includes my SQL connection user/pass) */
//include($_SERVER['DOCUMENT_ROOT']."/datatables/mysql.php");

* no need to edit below this line
*/
/*
* MySQL connection
*/
$gaSql['link'] = mysql_pconnect($gaSql['server'], $gaSql['user'], $gaSql['password'] ) or
die('Could not open connection to server');
mysql_select_db($gaSql['db'], $gaSql['link']) or
die('Could not select database '. $gaSql['db']);
/*

mysql_real_escape_string($_GET['iDisplayLength']);
}
/*

$sOrder = "";
if (isset($_GET['iSortCol_0']))
{
$sOrder = "ORDER BY ";

太多的代码的详细信息，并在其目前的形式，而不是我可以重现的东西来测试答案。甚至不知道你在哪里指定通配符。但一般的答案可能是“不要使用通配符搜索”。 （“Doc，当我这样做时会很痛苦。”） – ghoti 2012-07-16 11:13:26
是的，我只是想排除特定搜索字段的通配符搜索而不是全部。请帮帮我。 – Bappa 2012-07-16 11:16:27
我没有在你的PHP中看到通配符搜索发生在admin_detail表的“特权”列上......偶尔没有在“过滤”部分或代码中的其他任何地方提及。 – ghoti 2012-07-16 11:24:43
