Removing data between tags?

[Solarpitch]

Hey Guys,

 

I have a html page and I want to set some markers or tags so when I submit the page, I can strip out content between those tags.

For example something like

 

<!-- STRIP -->

.. html content la la la..

<-- END STRIP -->

 

or have a div with a class

<div class="strip">

... html content la la la

</div>

 

A. Which would be the best one?

B. How can I do this with ereg exp?

[betterphp]

well if you have the contents of the page as a string then you can use preg_replace

 

$stripped = preg_replace('#<!-- STRIP -->(.*)<-- END STRIP -->#s', '', $string);

 

but if this is actually a php page you can just use an if statement

[AbraCadaver]

I prefer:

 

<!-- STRIP -->
.. html content la la la..
<-- END STRIP -->

 

And this should work:

 

$output = preg_replace('/<--STRIP-->.*?<--END STRIP-->/s', '', $input);

[Solarpitch]

Thanks guys but neither seem to work.. I tried:

 

$code = preg_replace('/<--STRIP-->.*?<--END STRIP-->/s', '', $this->input->post('content'));

 

$code = preg_replace('#<!--STRIP-->(.*)<--END -STRIP->#s', '', $this->input->post('content'));

 

Very strange.. the content is coming through and when I save the code to the database directly after this call, everything is still inside the tags.

$string = 'Hey Guys,

$stripped = preg_replace('#<!-- STRIP -->(.*)<-- END STRIP -->#s', '', $string);

echo $stripped;

This example worked for me, although the ( brackets are not necessary.

 

Can you post your full code ?

[Solarpitch]

Actually,

 

I'm sending the post using Ajax where I need to escape() the html...

 

$(function() {
$(".save_newsletter").click(function() {

	var id = $(this).attr("id");
	var val = escape($("#content").html());
// escape
	var dataString = 'content='+ val;

	$.ajax({
		type: "POST",
		url: "<?php echo site_url(); ?>newsletter/save_newsletter/"+id,
		cache: false,
		data: dataString,
		success: function(html){
			$('.success').prepend(html);
		}
		});
	 return false;
});
});

 

This could be causing a problem?

 

EDIT: it must be, after it's escaped it sends through as .. 205px%3B%20border%3A%201px%20dashed% etc

But appears as normal in the database after the post and insert.

[betterphp]

well you could use the escaped versions of < and > in the regex, and what ever else it changes of course.

[Solarpitch]

<!--STRIP--> escaped as %0A%3C%21--STRIP--%3E%0A

 

So like this...

 

$code = preg_replace('#%0A%3C%21--STRIP--%3E%0A(.*)%0A%3C%21--ENDSTRIP--%3E%0A#s', '', $this->input->post('reply_content'));

 

 

[Solarpitch]

That doesnt work either actually.

[betterphp]

if you do

 

echo $this->input->post('reply_content');

 

that is what you need to be working with.

 

Also can you post the full thing ??

[Solarpitch]

 

Here's the code...

 

Save - submit call to Ajax

<a href="#" class="save_newsletter" id="<?php echo $template_id; ?>">Save</a>

 

 

Ajax - get html from <div class="content"></div>

$(function() {
$(".save_newsletter").click(function() {

	var id = $(this).attr("id");
	var val = escape($("#content").html());

	var dataString = 'content='+ val;

	$.ajax({
		type: "POST",
		url: "<?php echo site_url(); ?>newsletter/save_newsletter/"+id,
		cache: false,
		data: dataString,
		success: function(html){
			$('.success').prepend(html);
		}
		});
	 return false;
});
});

 

HTML - that was sent to the Ajax function from the content div with the tags

<!--ENDSTRIP-->

 

 

PHP - Get posted code from Ajax and save to DB

public function save_newsletter()
{

	$code = preg_replace('#<!--STRIP-->(.*)<--ENDSTRIP-->#s', '', $post);

	$insert = array(
                'code' => $code,
	'client_id' => $this->session->userdata('client_id'),
	'client_uri' => $this->session->userdata('client_uri'),
               );

	$this->Newsletter_model->save_newsletter($insert);
}

 

 

[betterphp]

you have <!--ENDSTRIP--> in your html but <--ENDSTRIP--> in the reg exp.

[Solarpitch]
