第一种方式找到该条信息的主键值，通过sql语句查询到该条数据，通过数组方式显示在INPUT的value值里
<body>
<?php
$yhm = $_GET["ids"];
require_once "./lib/DBDA.class.php";
$db = new DBDA();
$sql = "select * from user where uid='{$yhm}'";
$arr = $db->query($sql);
?>
<form>
<div>用户名:<input type="text" name="yhm" value="<?php echo $arr[0][0] ?>" /></div>
<div>密码：<input type="text" name="pwd" value="<?php echo $arr[0][1] ?>" /></div>
<div>姓名：<input type="text" name="uname" value="<?php echo $arr[0][2] ?>"/></div>
<div>性别：<input type="radio" name="sex" value="1" <?php echo $arr[0][3]?"checked=checked":"" ?>/>男
<input type="radio" name="sex" value="0" <?php echo $arr[0][3]?"":"checked=checked" ?> />女</div>
<div>生日：<input type="text" name="birthday" value="<?php echo $arr[0][4] ?>"/></div>
</form>
php带入的这种在性别这种单选框时
<?php echo $arr[0][3]?"checked=checked":"" ?>加入判断
<select></select>里面加判断if($arr[0][3]==$v[0]){echo "<option value='{$v[0]}' selected="selected">{$v[1]}</option>";}else{
echo "<option value='{$v[0]}'>{$v[1]}</option>"来实现选中状态。
}
ajax方式
<form action="updatechuli.php" method="post">
<div class="form-group"><label for="ucode">人员编号：</label><select name="ucode" class="form-control" id="ucode">
<?php
require_once "../lib/DBDA.class.php";
$db = new DBDA;
$sql = "select ucode from users";
$arr = $db->query($sql);
foreach($arr as $v){
echo "<option value='{$v[0]}'>{$v[0]}</option>";
}
?>
</select></div>
<div class="form-group"><label for="uid">用户名：</label><input type="text" class="form-control" name="uid" id="uid"></div>
<div class="form-group"><label for="pwd">密码：</label><input type="text" class="form-control" name="pwd" id="pwd"></div>
<div class="form-group"><label for="uname">姓名：</label><input type="text" class="form-control" name="uname" id="uname"></div>
<div class="btn-group" data-toggle="buttons">
