[英]PHP Update MySQL table using HTML form
I am trying to update my MySQL table by using a form in an HTML page. 我试图通过使用HTML页面中的表单来更新我的MySQL表。
This is my PHP code 这是我的PHP代码
<?php
ob_start();
session_start();
require_once 'dbconnect.php';
if( !isset($_SESSION['client']) ) {
header("Location: homepage_login.php");
exit;
}
// select loggedin users detail
$res=mysql_query("SELECT * FROM clients WHERE client_id=".$_SESSION['client']);
$userRow=mysql_fetch_array($res);
if( isset($_POST['btn-book']) ) {
$sql="UPDATE appointments SET date='$slot_date', line='$slot_line', reason='$reason' WHERE id='$id'";
$result=mysql_query($sql);
if($result){
echo "Successful";
}
else {
echo "ERROR";
} }
?>
And my HTML form 还有我的HTML表单
<form action"" method"post">
<p>Date: <input type="text" id="datepicker" name="date"></p>
<br>
<br>
Select a line:
<ol id="selectable" name="line">
<li class="ui-widget-content">Line 1</li>
<li class="ui-widget-content">Line 2</li>
<li class="ui-widget-content">Line 3</li>
<li class="ui-widget-content">Line 4</li>
<li class="ui-widget-content">Line 5</li>
<li class="ui-widget-content">Line 6</li>
<li class="ui-widget-content">Line 7</li>
</ol>
<br>
<br>
<p>Reason for appointment: <input type="text" name="reaosn"></p>
<div class="form-group">
<button type="submit" class="btn btn-block btn-primary" name="btn-book">Book</button>
</div>
</form>
These are on the same page by the way. 顺便提一下,它们在同一页面上。 So what I need to happen is for when someone fills out the form and hits the submit button, the PHP code will update my MySQL table on a specific already made record.
所以我需要发生的是当有人填写表单并点击提交按钮时,PHP代码将在特定的已经创建的记录上更新我的MySQL表。
I'm not sure if I somehow need to specify what record I want to update or if I've just completely messed up actually updating my table. 我不确定我是否需要指定我想要更新的记录,或者我是否完全搞砸了实际更新我的表格。
So, my questions is: 所以,我的问题是:
How do I update a specific record in my table using a HTML form and PHP code? 如何使用HTML表单和PHP代码更新表格中的特定记录?
in the form you have to change like this 在表格中你必须像这样改变
<form method="post" action="same_page.php">
the php change with below code. 用以下代码改变php。
<?php
ob_start();
session_start();
require_once 'dbconnect.php';
if( !isset($_SESSION['client']) ) {
header("Location: homepage_login.php");
exit;
}
// select loggedin users detail
$res=mysql_query("SELECT * FROM clients WHERE client_id='$_SESSION[client]'");
$userRow=mysql_fetch_array($res);
$id=$userRow['client_id'];
if( isset($_POST['btn-book']) ) {
$slot_date= $_POST['date'];
$reason=$_POST['reason'];
$slot_line=$_POST['line'];
$sql="UPDATE appointments SET date='$slot_date', line='$slot_line', reason='$reason' WHERE id='$id'";
$result=mysql_query($sql);
if($result){
echo "Successful";
}else {
echo "ERROR";
}
}
?>
Just echo all the values on form 只需回显表单上的所有值
for eg: <p>Date: <input type="text" id="datepicker" name="date"></p>
into <p>Date: <input type="text" id="datepicker" value="<?php echo $result['date']; ?> " name="date"></p>
例如:
<p>Date: <input type="text" id="datepicker" name="date"></p>
进入<p>Date: <input type="text" id="datepicker" value="<?php echo $result['date']; ?> " name="date"></p>
