我正在尝试从我的评论表中的所有提交的评论中检索“姓名,电子邮件和消息”列,并将其显示在页面上,但不显示任何内容。这很奇怪,因为我的博客帖子几乎完全相同,而且工作正常。
php code
$sql = "SELECT name, email, message FROM comments";
$result = mysqli_query($db_server, $sql);
while($row = mysqli_fetch_assoc($result))
{
$data[] = $row;
}
$tpl->assign('data', $data);
$tpl->display('comments.tpl');
html
<table>
{if $signedin}
<tr>
<td>Username:</td>
</tr>
{foreach from=$data item=item key=key}
<tr>
<td>{$item.name}</td>
<td>{$item.email}</td>
<td>{$item.message}</td>
<tr>
{/foreach}
{else}
Sign in to view comments.
{/if}
</table>
我做错了什么?
编辑:从recipes.php添加工作代码
require_once 'config.php';
session_start();
include 'is-signed-in.php';
$data = array(); //initalize a container
$query = "SELECT * from recipes";
$result = mysqli_query($db_server, $query);
if ($result->num_rows > 0) {
//fetch rows
while($row = $result->fetch_assoc()) {
$data[] = $row; //push the array inside the row
}
}
$tpl->assign('values', $data);
// Display template
$tpl->display('myrecipes.tpl');
recipes.tpl
{if $signedin}
{foreach from=$values key=k item=value}
<p>{$value.user_id_fk}</p>
<a href="<?php echo url_for('recipes-page.php'); ?>"><h2>{$value.title}</h2></a>
<p>Date: {$value.submission_date}</p>
<p>{$value.instructions}</p>
<p>Category: {$value.category}</p>
<form action="" method="post">
<a href="{$delete}">Delete</a>
{/foreach}
{else}
You are currently not signed in.
{/if}

显然我的问题出在我的.tpl中,没有任何内容显示在表格中。它真的应该,但我确实在h1元素中有一个迷路锚标签。所以这解决了这个问题。
<h1>Comments</h1>
{foreach from=$data item=item key=key}
<div>
<p>Name: {$item.name}</p>
<p>Email: {$item.email}</p>
<p>Message: {$item.message}</p>
</div>
{/foreach}
