ob_flush()

[Destramic]

hey guys...im having a issue when using ob_flush()...what im getting is a 1 at the end of my html depending on how many templates i render...in this instance i get 11 at the end of my html in the browser,

 

render in my view class:

	public function render($file_name)
	{	
		if (preg_match("/\.html$/i", $file_name))
		{
		    ob_start();
			extract($this->_variables);
			require_once PRIVATE_DIRECTORY . 'application' . DS . 'views' . DS . $file_name;
		    $body = ob_flush();
		}
 
	   $this->_repsonse->append_body($body);
	} 

inside my controller:

$this->view->render('template.html');

template.html

my header is here

<? $this->view->render('content.html') ?>

my footer here

how the source looks in browser:

my header is here

content is here

my footer here11

any idea why i get 1's after my html when using ob_start() please?

 

thank you

Have you tried commenting out the output buffer block of code to verify that's what's causing the issue? For example, you could try something like this:

public function render($file_name)
{ 
    /*
    if (preg_match("/\.html$/i", $file_name))
    {
        ob_start();
        extract($this->_variables);
        require_once PRIVATE_DIRECTORY . 'application' . DS . 'views' . DS . $file_name;
        $body = ob_flush();
    }
    */
 
    $body = "<div>All good here ($file_name)</div>";
    $this->_repsonse->append_body($body);
}

 

Perhaps the issue is caused by append_body()...

thanks for your post

 

if i use

$body = ob_get_contents();

instead then i get no 11 at end of the </html> tag...as for it being the response there's nothing  in there that could cause it... =/

Yeah, you're right. That seems odd since ob_flush() isn't supposed to return anything.

any ideas on how i can sort this please?

What do you mean by "sort this"? Is the program still not working? Or are you trying to change the sort order of something?

[Destramic]

well its ob_flush() i need to use...but still getting the return of 1's at the end of the html...so i meant how to sort so it stops showing the 1's?

Well, I assume that the following line of code would display content on the screen without buffering the output:

require_once PRIVATE_DIRECTORY . 'application' . DS . 'views' . DS . $file_name;

Instead of displaying it directly to the screen, it looks like you want to assign the content to $body. If that's correct, you would use ob_get_contents(). Note that this function doesn't clear the buffer, so you'll need to also call ob_end_clean().

 

You could try changing this

public function render($file_name)
{ 
    if (preg_match("/\.html$/i", $file_name))
    {
        ob_start();
        extract($this->_variables);
        require_once PRIVATE_DIRECTORY . 'application' . DS . 'views' . DS . $file_name;
        $body = ob_flush();
    }
 
    $this->_repsonse->append_body($body);
}

To this

public function render($file_name)
{ 
    if (preg_match("/\.html$/i", $file_name))
    {
        ob_start();
        extract($this->_variables);
        require_once PRIVATE_DIRECTORY . 'application' . DS . 'views' . DS . $file_name;
        $body = ob_get_contents();
        ob_end_clean();
    }
 
    $this->_repsonse->append_body($body);
}

Typo?

 

$this->_repsonse->append_body($body);

$this->_response->append_body($body);

[Barand]

ob_flush(), contrary to the manual, appears to return true (1)

ob_start();
echo "";
$body = ob_flush();
var_dump($body);      //--> bool(true)
