使用我之前的个人资料视图,它会抓取搜索到的ID并使用此查询显示它:
$dn = mysql_query('select firstname, lastname, age, id, background from users where id="'.$id.'"');
然而,我目前通过搜索到的网址查看活动页面。所以网址是socialnetwk所以
$dn = mysql_query('select eventname, about, url, comment, post, msg, member_id, author_id, id from events where url="'.$id.'"');
我不确定如何解决此问题,因为我已经使用续集专业版,而且似乎我需要' '围绕网址名称。我怎么还没知道如何在查询中包含这个
网址是一列,而非实际网址
以下是代码:
<?php
//We check if the users ID is defined
if(isset($_GET['id']))
{
$id = intval($_GET['id']);
//We check if the user exists
$dn = mysql_query('select eventname, about, url, comment, post, msg, member_id, author_id, id from events where url="'.$id.'"');
if(mysql_num_rows($dn)>0)
{
$dnn = mysql_fetch_array($dn);
//We display the user datas
if($dnn['id']!='')
{
}
else
{
echo 'This user dont have an avatar.';
}
?>

已更新以符合您编辑的代码:
在使用预备陈述的情况下:
<?php
//We check if the users ID is defined
if(isset($_GET['id'])){
$id = intval($_GET['id']);
//We check if the user exists
$dn = 'select eventname, about, comment, post, msg,
member_id, author_id, id from events where url=?';
if($stmt=$dbc->prepare($dn)){
$stmt->bind_param('s',$id); //your URL is a string
$stmt->execute(); //returns false if fails
$stmt->bind_result($eventname, $about, $comment, $post,
$msg, $member_id, $author_id, $id); //don't need to
//bind the url, since you already know it
$stmt->fetch();
$stmt->free_result();
if($stmt->num_rows>0) {
//We display the user datas
echo "$eventname, $about, $comment ..."; // the bound results
}
$stmt->close();
$dbc->close();
}
if($dnn['id']!=''){
// do something here
} else {
echo 'This user dont have an avatar.';
}
?>
这假定$dbc
是您的数据库连接。
*注意,您将$ _GET [&#39; id&#39;]值更改为整数,但它也是一个URL(字符串)。这需要进行协调,以使您的代码能够正常运行*
