I have a form that displays the results from a survey into a webpage. At the moment, when a user clicks on the 'View Here' it takes them to the individual entry for that ID. When it is clicked I would like it to also show additional results (also part of the results from the same database).
Any idea how I do this? Just to clarify, it should not show until the ID is clicked to single out that entry - otherwise it shows them all in full one after the other.
$.ajax({
url: 'js/users.php',
dataType: 'json',
success: function(data){
var id = data[0];
var fName = data[1];
var lName = data[2];
$('#output').html("<b>id: </b>"+id+"<b> first name: </b>"+fname+"<b> last name: </b>"+lname);
},
error: function(data){
alert(JSON.stringify(data));
}
});
Additional code that I would like to show once 'View Here' is clicked (so when the individual entry is shown):
<?php
try {
$handler = new PDO('mysql:host=localhost;dbname=***', '***', '***');
$handler->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch(PDOException $e) {
echo $e->getMessage();
die();
}
class guestquestionnaireEntry {
public $id, $date_submitted,
$entry;
public function __construct()
{
$this->entry = "
<table border='1' align='center'>
<tr class='tablelist' style='font-size: 8pt;' ><td width='5%' colspan='2'>{$this->ID}</td><td width='40%' colspan='2'><b>Date Received: </b>{$this->date_submitted}</td><td width='45%' colspan='2'>{$this->name}</td><td width='10%'><a href=\"?ID={$this->ID}\">View here</a> </td></tr>
</table>
";
}
}
SELECT DATE_FORMAT(date_submitted, '%m/%d/%Y') AS date_submitted FROM guestquestionnaire
// Checks if the submitted is a number. If so, isolates the ID and adds "where" clause
$id = (!empty($_GET['ID']) && is_numeric($_GET['ID']))? " where ID = '".$_GET['ID']."'" : "";
// Add the $id to the end of the string
// A single call would be SELECT * FROM guestquestionnaire where ID = '1'
$query = $handler->query("SELECT * FROM guestquestionnaire{$id}");
$query->setFetchMode(PDO::FETCH_CLASS, 'guestquestionnaireEntry');
while($r = $query->fetch()) {
echo $r->entry, '<br>';
}
?>

看看这是否有效。我没有测试过，所以请确保保存到目前为止所有内容的副本。它需要填写数据库凭据：
