Fatal error: Using $this when not in object context
提问by designer-trying-coding
here is the part if having error.
如果有错误，这里是部分。
Fatal error: Using $this when not in object context in /pb_events.php on line 6
致命错误：在第 6 行的 /pb_events.php 中不在对象上下文中时使用 $this
line 6 is: $jpp = $this->vars->data["jpp"];
第 6 行是： $jpp = $this->vars->data["jpp"];
function DoEvents($this) {
global $_CONF, $_PAGE, $_TSM , $base;
$jpp = $this->vars->data["jpp"];
$cache["departments"] = $this->db->QFetchRowArray("SELECT * FROM {$this->tables[job_departments]}");
$cache["locations"] = $this->db->QFetchRowArray("SELECT * FROM {$this->tables[job_location]}");
$cache["names"] = $this->db->QFetchRowArray("SELECT * FROM {$this->tables[job_names]}");
$cache["categories"] = $this->db->QFetchRowArray("SELECT * FROM {$this->tables[job_categories]}");
Thanks a lot! appreciate!
非常感谢！欣赏！

$this only makes sense in methods, not in functions
$this 只在方法中有意义，在函数中没有意义
this is ok
还行吧
class Foo {
function bar() {
$this->...
this is not
这不是
function some() {
$this->
// edit: didn't notice he passes "$this" as parameter
// 编辑：没有注意到他将“$this”作为参数传递
advice: simply replace "$this" with "$somethingElse"
建议：只需将“$this”替换为“$somethingElse”

You cannot pass $thisto a procedural function. $thisis a reserved variable.
您不能传递$this给过程函数。$this是一个保留变量。

As per my comments.
You want to use $thisas passed variable and php doesn't allow it outside class methods body.
根据我的评论。您想使用$this作为传递的变量，而 php 不允许在类方法主体之外使用它。
function DoEvents($obj) {
global $_CONF, $_PAGE, $_TSM , $base;
$jpp = $obj->vars->data["jpp"];
$cache["departments"] = $obj->db->QFetchRowArray("SELECT * FROM {$obj->tables[job_departments]}");
$cache["locations"] = $obj->db->QFetchRowArray("SELECT * FROM {$obj->tables[job_location]}");
$cache["names"] = $obj->db->QFetchRowArray("SELECT * FROM {$obj->tables[job_names]}");
$cache["categories"] = $obj->db->QFetchRowArray("SELECT * FROM {$obj->tables[job_categories]}");

You have to make the object first.
你必须先制作对象。
$object=new Myobject;
DoEvents($object);
