我有一个完美的PHP表单,直到有一天它只将结果提交到数据库。我没有更改代码,突然之间因为未知原因提交了两次所有结果。我已经谷歌了,无法找到问题。这是我的代码:
<?php
$jinput = JFactory::getApplication()->input;
if(isset($_POST['submit'])) {
$db = JFactory::getDbo();
$query = $db->getQuery(true);
$user = JFactory::getUser();
$userID = $user->get( 'id' );
$date = date("Y/m/d");
$description = $jinput->get('description', null , null);
$subsection = $jinput->get('subsection', null , null);
$urgency = $jinput->get('urgency', null , null);
$status = "Waiting Attention";
$columns = array('userid', 'rdate', 'description', 'area', 'subsection', 'urgency', 'status');
$values = array($userID, $db->quote($date), $db->quote($description), $db->quote($selected), $db->quote($subsection), $db->quote($urgency), $db->quote($status));
$query
->insert($db->quoteName('#__website_issues'))
->columns($db->quoteName($columns))
->values(implode(',', $values));
$db->setQuery($query);
$db->execute();
echo "<h4>Thank You! Issue Successfully Reported!";
}
echo "<table style='text-align:center;text-align:center;margin-left:41%;'>";
echo "<tr><td><h4>Report Website Issue</h4></td></tr>";
echo "<tr><td><form method='post'><select name='area' onchange='this.form.submit()'>
<option value=''>Select Website Area</option>
<option value='General'>General</option>
<option value='Emails'>Emails</option>

<option value='Reviews'>Reviews</option>
<option value='Store'>Store</option>
<option value='Toolkit'>Toolkit</option>
<option value='Membership'>Membership</option>
<option value='Other'>Other</option>
</select></form>
</td></tr>";
echo "<form method='post'>";
$selected = $jinput->get('area', null, null);
echo "<tr><td><h5><center>Current Area Selected: $selected</center></tr></td></h5>";
if($selected == 'General') {
echo "<tr><td><input type='text' name='subsection' placeholder='Subsection'></td></tr> ";
}
else if($selected == 'Emails') {
echo "<tr><td><select name='subsection'>
<option value=''>Select Email System</option>
<option value='Contact Error'>Contact Emails</option>
<option value='Notification'>Notifications</option>

}
else if($selected == 'Store') {
echo "<tr><td><input type='text' name='subsection' placeholder='Store Area'></td></tr> ";
}

echo "<tr><td><input type='text' name='subsection' placeholder='Specific Tool'></td></tr> ";
}

}

<option value=''>Select Urgency</option>
<option value='Minor'>Minor</option>

echo "<tr><td><textarea rows='6' cols='50' name='description' placeholder='Please Describe The Issue'></textarea></td></tr>";
// Submit
echo "<tr><td><input type='submit' class='btnsubmit' name='submit' value='Submit Issue'>";
echo "</form></table><hr>";
?>
</body>
提前致谢!

也许您应该在插入数据后重定向用户,这样页面刷新将避免再次插入数据:
<?php
...
$db->setQuery($query);
$db->execute();
header('Location: '.$_SERVER['PHP_SELF']);
exit();
另一点是你可以在js中首次提交后禁用表单提交。
