【教程】会员登录后只显示头像的方法

很久没写教程了，因为最近考试的原因暂时没有写更多的教程，今天就来写一个有关易优会员登录后头像的问题，大家在做站的时候，会碰到，想登录后只显示头像而不显示账号昵称或者用户名。对于目前的逻辑，系统暂时还不能实现，只能应用于{eyou:user type=’info’}里面的头像加昵称

才可以。这样会碰到瓶颈，有的模板需求只要单独显示头像就好不要显示昵称

可是你怎么调用是无法实现的。

所以这种的确有点头疼。小秋今天就利用user登录会员标签来模拟复制一个逻辑出来，来填充这个所谓的不足吧，

效果如下：

如果你想登录显示用户名/昵称你就正常的官方标签即可。

如果你想登录后只显示头像，那么就用以下标签：

{eyou:users type=’open’}

{eyou:users type=’cart’}

{$field.hidden}

{/eyou:users}

{eyou:users type=’login’}

{$field.hidden}

{/eyou:users}

{eyou:users type=’reg’}

{$field.hidden}

{/eyou:users}

{eyou:users type=’logout’}

{$field.hidden}

{/eyou:users}

代码有点多,因为是全新复制一个标签的结果,但我相信可以结合代码出来,只是不想费脑,就直接全新复制标签出来了,请多见谅~希望官方后续整合下.

以下是修改的文件部分：

打开applicationapicontroller

Ajax.php 文件打开大概在（179行）

找到以下

/**

* 检验会员登录

public function check_user()

{

if (IS_AJAX) {

$type = input(‘param.type/s’, ‘default’);

$img = input(‘param.img/s’);

$users_id = session(‘users_id’);

if (‘login’ == $type) {

if (!empty($users_id)) {

$currentstyle = input(‘param.currentstyle/s’);

$users = M(‘users’)->field(‘username,nickname,head_pic’)

->where([

‘users_id’ => $users_id,

‘lang’ => $this->home_lang,

])->find();

if (!empty($users)) {

$nickname = $users[‘nickname’];

if (empty($nickname)) {

$nickname = $users[‘username’];

}

$head_pic = get_head_pic($users[‘head_pic’]);

if (‘on’ == $img) {

$users[‘html’] = “<img class='{$currentstyle}’ alt='{$nickname}’ src='{$head_pic}’ />”;

} else {

$users[‘html’] = $nickname;

}

$users[‘ey_is_login’] = 1;

$this->success(‘请求成功’, null, $users);

}

$this->success(‘请先登录’, null, [‘ey_is_login’=>0]);

}

else if (‘reg’ == $type)

{

if (!empty($users_id)) {

$users[‘ey_is_login’] = 1;

} else {

$users[‘ey_is_login’] = 0;

}

$this->success(‘请求成功’, null, $users);

}

$users[‘ey_cart_num_20191212’] = Db::name(‘shop_cart’)->where([‘users_id’=>$users_id])->sum(‘product_num’);

} else {

$users[‘ey_is_login’] = 0;

$users[‘ey_cart_num_20191212’] = 0;

}

$this->success(‘请求成功’, null, $users);

}

$this->error(‘访问错误’);

}

下面新增以下代码：

$img = input(‘param.img/s’);

$users_id = session(‘users_id’);

‘lang’ => $this->home_lang,

])->find();

$head_pic = get_head_pic($users[‘head_pic’]);

if (!empty($users)) {

$nickname = “<img src='{$head_pic}’>”;

if (empty($nickname)) {

$nickname = $users[‘username’];

}

$head_pic = get_head_pic($users[‘head_pic’]);

else if (‘reg’ == $type)

{

if (!empty($users_id)) {

保存

打开：corelibrary hink emplate aglib目录

Eyou.php文件打开

找到：（89行）

‘user’ => [‘attr’ => ‘type,id,key,mod,empty,currentstyle,img,txt,txtid’],

下面新增以下代码：

‘users’ => [‘attr’ => ‘type,id,key,mod,empty,currentstyle,img,txt,txtid’],

再找到以下代码（大概2626行）

在下面新增以下代码：

到这里教程就差不多了。

为何要做2个user登录标签因为有的模板只需要登录后显示单纯头像，一部分有的地方还是需要显示昵称所以因需所调用吧。

重复说下以上调用的标签为：

{eyou:users type=’open’}

{eyou:users type=’cart’}

{$field.hidden}

{/eyou:users}

{eyou:users type=’login’}

{$field.hidden}

{/eyou:users}

{eyou:users type=’reg’}

{$field.hidden}

{/eyou:users}

{eyou:users type=’logout’}

{$field.hidden}

{/eyou:users}

不过一般登录只需

{eyou:users type=’login’}

{$field.hidden}

{/eyou:users}

即可
