Php 数据表搜索选项

我使用的是datatables插件，我正在搜索一个名为“privilege”的字段。prvilege的值为“超级管理员”和“管理员”。对于通配符搜索，每当我按“admin”搜索时，都会显示admin和superadmin的记录。如何解决这个问题。我的代码如下：

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
           ]
} );

函数fnFilterColumn（i）
{
$（'#示例'）.dataTable（）.fnFilter（
$（“#col”+（i+1）+“_filter”）.val（），i，true，false）；
}
$（文档）.ready（函数（）{
var oTable=$（'#示例'）。数据表（{
“bProcessing”：正确，
“sAjaxSource”：“datatabledb.php”，
“bJQueryUI”：没错，
“sPaginationType”：“完整编号”，
“sDom”：“Tlfrtip”，
“可旋转工具”：{
“阿布顿”：[
{
“性倾向”：“csv”，
“sButtonText”：“保存到CSV”
}
]
},
“语言”：{
“搜索”：“搜索所有列：”
},
“aoColumns”：[
无效的
{“bSortable”：false}，//禁用复选框标头的排序属性
空，空，空，空，空，空，空，空，空，空
]
} );

在datatabledb.php文件中，我写下了我的db代码，如下所示：

我不知道为什么这么长时间都没有回答这个问题。你只要改变一下就行了

$sWhere .= "`".$aColumns[$i]."` LIKE '%".mysql_real_escape_string( $_GET['sSearch'] )."%' OR ";

到

删除通配符

您也可以对单个列执行此操作。如果您想了解太多代码的详细信息，请以当前形式告知我。我无法复制这些代码来测试答案。甚至不确定您在哪里指定了通配符。但一般的答案可能是“不要使用通配符进行搜索”(“Doc，我这样做会很痛。”）是的，没错，我只是想排除对特定搜索字段的通配符搜索，而不是对所有字段的通配符搜索。请帮助我。我看不到在您的PHP中，在admin_detail表的“privilege”列上发生通配符搜索……顺便说一句，“Filtering”中没有提到这一点“节，或代码中的任何其他部分。我想我必须在js节中进行配置。是吗？你找到解决方案了吗？。因为我也面临同样的问题…我加入了..我的记录被正确地看到了…但是当我搜索时，其他记录也会被看到（搜索后）
$sWhere .= "`".$aColumns[$i]."` LIKE '".mysql_real_escape_string( $_GET['sSearch'] )."' OR ";
