PHP IDE :: NuSphere Forums :: View topic - Code completion on "$this" in an included file

Posted: Mon Jan 24, 2011 9:40 am

Let's say:

Code:

class MyClass
{
public function test()
{
include('inc.php');
}

public function sayHi()
{
echo "hi";
}

}

and, in "inc.php":

Code:

/**
* @var MyClass
*/
$this->

I'd like phpEd to suggest me "sayHi()" here, but it doesn't. The "@var MyClass" doesn't seem to work on "$this".

Is there a way I can let phpEd knows the type of "$this" in an included file?

i don't get what you are trying to do with $this..

I think my message is pretty clear willbaker..

Actually I agree with willbaker... How can you have a "$this" in an include file that is supposed to be a class defined in another file? Unless you are using $this as a regular variable and that's never a good idea... perhaps you can share a bit more code?

Well, I'll try to be more clear then... Embarassed

Template.php

Code:

class Template
{
$name = "";
public function echosafe($str)
{
echo htmlentities($str, ENT_QUOTES, 'UTF-8');
}

public function run($name)
{
$this->name = $name;
include("myTemplate.tpl.php");
}
}

myTemplate.tpl.php

Code:

<html>

<head>
</head>

<body>
<?php $this->echosafe($this->name) ?>
</body>

</html>

an finally, let's say my code is ran with:

Code:

$template = new Template();
$template->run("John Doe");

--------------
My problem:

In "myTemplate.tpl.php" I'd like to let phpEd know that "$this" is an instance of the "Template" class, so phpEd can suggest me "echosafe()" when I type <?php $this->

I tried to let it know using the "@var Template" syntax, just above a $this variable in "myTemplate.tpl.php", but it doesn't seem to work!

Hmm that makes a lot more sense. And are you sure you did like
/** @var Template */
and not
/* @var Template */
by mistake?

PhpED only parses blocks if they start with 2 asterisks.

Yes, I did use "/** @var Template */" ,

This syntax always work, except for "$this".

Guess PhpED doesn't allow override on $this then, although it probably should if it can't determine the type itself.

PhpED quite correctly always expects $this to represent the current class context and you can't reassign that. Because that template isn't within a class definition, I don't think you will get code completion to work on $this at coding time, although at run-time with debug, PhpED will be able to see the context of $this from the debugger.

However, this works:

Code:

class Template {
public function hello() {
return 'value';
}
}

/**
* @var Template
*/
$_this = $this;
$_this->;

Place your cursor after $_this-> and you get code completion. Because $_this is an assignment of $this (rather than a copy or clone), the new object works as expected.
