先生，我的问题是首先我会输入Rollno并且没有提交我必须从数据库中获取有关rollno的详细信息而不刷新然后在同一页面中我将输入登记号并且我必须再次获得有关的详细信息来自数据库的入藏号。这可以使用vb完成，但如果我想在PHP中完成，我该怎么办呢。

您可以使用AJAX实现目标。如果您不了解Ajax，请阅读here。 上述解决方案将添加以下内容：
<input name="Rollno" type="text" onblur="myFunction(this.value)" />
假设您想在
中输入值 <input name="Branch" type="text" />
然后将其更改为
<input name="Branch" type="text" id="change" value=""/>
现在是javascript部分
<script>
function myFunction(r){
if (window.XMLHttpRequest) {
// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp = new XMLHttpRequest();
} else {
// code for IE6, IE5
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange = function() {
if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
document.getElementById("change").value= xmlhttp.responseText;
}
}
xmlhttp.open("GET","getdetails.php?roll="+r,true);
xmlhttp.send(); }
</script>
现在是php部分
if(isset($_GET['roll'])){
// get the data for roll from the database and simply echo them here;}
}
这只是帮助您理解Ajax的最小解决方案。

您也可以使用jQuery。
<input type="text" id="get">
<div id="result"></div>
你的jQuery代码。
$("#get").blur(function (){
var val = $('#get').val();
$.post('data.php', {value: val}, function (data) {
$('#result').html(data);
}
}
在你的php文件中
if(isset($_POST['value'])){
$results = database query/results
echo $results;
}
