php thinkphp controller

This time I will bring you a detailed explanation of the steps for displaying thinkPHP controller variables in the template. What are the precautions for displaying thinkPHP controller variables in the template? The following is a practical case, let's take a look.

Variables in the controller

public function register() {
  $type = I(&quot;param.type&quot;);//1.学生注册 2.教师注册 3.其他注册
  $this -&gt; assign(&quot;type&quot;, $type);
    //q全部部门
  $depart1 = M(&quot;Depart&quot;) -&gt; where(&quot;status=1 and fid=0&quot;) -&gt; order(&quot;id asc&quot;) -&gt; select();
  $this -&gt; assign(&quot;depart1&quot;, $depart1);
  $this -&gt; display();
}

Copy after login

Reference position one in the template: In the php code, use $i; directly

&lt;php&gt;
  echo $i;
&lt;/php

Copy after login

Reference position two in the template: Apply directly in the template {$i} or class="{$unlogined}"

&lt;font color=&quot;red&quot;&gt;注意：1.非相关人员，严禁注册。{$i}&lt;/font&gt;&lt;br&gt;
&lt;php&gt;
  $logined = is_array($_SESSION[&#39;userInfo&#39;]) ? &quot;&quot; : &quot;hide-p&quot;;
  $unlogined = $logined == &quot;hide-p&quot; ? &quot;&quot; : &quot;hide-p&quot;;
&lt;/php&gt;
&lt;p id=&quot;unlogined-p&quot; class=&quot;{$unlogined}&quot;&gt;

Copy after login

Reference position three in the template: Used in template tag , such as used in condition, without adding {}.

&lt;if condition=&quot;$type neq 4&quot;&gt;
  &lt;p class=&quot;form-group&quot;&gt;
    &lt;label for=&quot;&quot; class=&quot;control-label col-sm-3&quot;&gt;一级部门: &lt;span class=&quot;text-danger&quot;&gt;*&lt;/span&gt;&lt;/label&gt;
    &lt;p class=&quot;col-sm-9&quot;&gt;
      &lt;select name=&quot;depart1_id&quot; id=&quot;depart1_id&quot; onchange=&quot;depart1change()&quot; class=&quot;form-control input-sm&quot;&gt;
        &lt;option value=&quot;-1&quot;&gt;-----请选择一级部门-----&lt;/option&gt;
        &lt;foreach name=&quot;depart1&quot; item=&quot;vo&quot;&gt;
          &lt;option value=&quot;{$vo.id}&quot;&gt;{$vo.name}&lt;/option&gt;
        &lt;/foreach&gt;
      &lt;/select&gt;
    &lt;/p&gt;
  &lt;/p&gt;
  &lt;p class=&quot;form-group&quot;&gt;
    &lt;label for=&quot;&quot; class=&quot;control-label col-sm-3&quot;&gt;二级部门: &lt;span class=&quot;text-danger&quot;&gt;*&lt;/span&gt;&lt;/label&gt;
    &lt;p class=&quot;col-sm-9&quot;&gt;
      &lt;select name=&quot;depart2_id&quot; id=&quot;depart2_id&quot; onchange=&quot;depart2change()&quot; class=&quot;form-control input-sm&quot;&gt;
        &lt;option selected=&#39;selected&#39;&gt;-----请先选择一级部门-----&lt;/option&gt;
      &lt;/select&gt;
    &lt;/p&gt;
  &lt;/p&gt;
  &lt;p class=&quot;form-group&quot;&gt;
    &lt;label for=&quot;&quot; class=&quot;control-label col-sm-3&quot;&gt;三级部门: &lt;span class=&quot;text-danger&quot;&gt;*&lt;/span&gt;&lt;/label&gt;
    &lt;p class=&quot;col-sm-9&quot;&gt;
      &lt;select name=&quot;depart3_id&quot; id=&quot;depart3_id&quot; class=&quot;form-control input-sm&quot;&gt;
        &lt;option selected=&#39;selected&#39;&gt;-----请先选择二级部门-----&lt;/option&gt;
      &lt;/select&gt;
    &lt;/p&gt;
  &lt;/p&gt;
&lt;/if&gt;
