表单和PHP结果显示在同一页面上
我在一个页面上有一个链接到PHP文件(操作)的表单,现在PHP结果显示在这个PHP文件/页面中.但我希望结果显示在带有表单的页面上.我已经彻底搜索过,无法在任何地方找到它.也许你们中的任何人都可以帮忙
代码:/citizens.php(主页)
<form method="post" action="/infoct.php">
<input type="text" name="ID" placeholder="ID">
<input name="set" type="submit">
</form>
代码:/infoct.php
<!DOCTYPE html>
<html>
<head>
<!-- <meta http-equiv="refresh" content="0; url=/citizens.php" /> -->
</head>
<body>
<?php {
$ID2 = isset($_POST['ID']) ? $_POST['ID'] : false;
}
$connect = mysql_connect('localhost', 'root', 'passwd');
mysql_select_db ('inhabitants');
$sql = "SELECT `Name`, `Surname`, `DOB`, `RPS`, `Address` FROM `citizens` WHERE ID = $ID2";
$res = mysql_query($sql);
echo "<P1><b>Citizen Identification number is</b> $ID2 </p1>";
while($row = mysql_fetch_array($res))
{
echo "<br><p1><b>First Name: </b></b>", $row['Name'], "</p1>";
echo "<br><p1><b>Surname: </b></b></b>", $row['Surname'], "</p1>";
echo "<br><p1><b>Date of birth: </b></b></b></b>", $row['DOB'], "</p1>";
echo "<br><p1><b>Address: </b></b></b></b></b>", $row['Address'], "</p1>";
echo "<br><p1><b>Background information: </b><br>", $row['RPS'], "</p1>";
}
mysql_close ($connect);
?>
</body>
</html>
我的固定代码归功于Marc B.
<form method="post">
<input type="text" name="ID" placeholder="ID">
<input name="set" type="submit">
</form>
<?php
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
$ID = isset($_POST['ID']) ? $_POST['ID'] : false;
$connect = mysql_connect('fdb13.biz.nf:3306', '1858208_inhabit', '12345demien12345');
mysql_select_db ('1858208_inhabit');
$sql = "SELECT `Name`, `Surname`, `DOB`, `RPS`, `Address` FROM `citizens` WHERE ID = $ID";
$res = mysql_query($sql);
if ($ID > 0) {
echo "<p><b>Citizen Identification number is</b> </p>";
while($row = mysql_fetch_array($res))
echo "<br><p><b>Surname: </b></b></b>", $row['Surname'], "</p>";
echo "<br><p><b>First Name: </b></b>", $row['Name'], "</p>";
echo "<br><p><b>Date of birth: </b></b></b></b>", $row['DOB'], "</p>";
echo "<br><p><b>Address: </b></b></b></b></b>", $row['Address'], "</p>";
echo "<br><p><b>Background information: </b><br>", $row['RPS'], "</p>";
mysql_close ($connect);
}
else {
echo "<p>Enter a citizen ID above</p>";
}
}
?>
DB Snap
单页表单+提交处理程序非常基本:
<?php
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
... form was submitted, process it ...
... display results ...
... whatever else ...
}
?>
<html>
<body>
<form method="post"> ... </form>
</body>
</html>
这就是真的.
