PHP echo with article-custom ID attribute help please

THE BLUE DRAGON · 2010-06-12 16:25:05

Hey!
I don’t know PHP yet.
I got code that should display the title of article #1 but it’s not working for me :/
(I’m using raw PHP in a page)

Here is an example:

<?php
$articlenumber = '1';
$articletitle = '<a href="/'.$articlenumber.'"><txp:article_custom id="'.$articlenumber.'"><txp:title /></txp:article_custom></a>';
echo '
<div>'.$articletitle.'</div>
';
?>

What is wrong please?
The $articlenumber var in the A link HREF attribute works good,
but not in the article_custom ID attribute :(

Try to wrap with parse() and remember to use <txp:php> if you are using php inside forms, pages or articles

<txp:php>
$articlenumber = ‘1’;
$articletitle = ‘<a href=”/’.$articlenumber.’”><txp:article_custom id=”’.$articlenumber.’”><txp:title /></txp:article_custom></a>’;
echo ‘
<div>’.parse($articletitle).’</div>
‘;
</txp:php>

Thanks it does works when using <txp:php>
but not with regular <?php after I set raw PHP to yes in the preferences.
What does really raw PHP means?
I just find it letting me using regular <?php tags instead of <txp:php> but is that what raw-PHP means please?

I got PHP code that if I enable the raw-php and use regular php tags it works good except of the txp-article-custom-id part.
but when I’m using <txp:php> I’m getting errors :/
You can see the code here (it’s the first code of – Retrieve/Manage comemnts)
You can see there that there are a lot of <?php ?> tags, and when I’m replacing them with <txp:php></txp:php> the code is not working good.

Hi Gil

I’m wondering if you actually do need to struggle with php at all. rah_external can parse most txp tags which you can then just include their content in any php enabled page by using

<txp:php>include($DOCUMENT_ROOT . "http://www.yoursite.tld/?rah_external_output=name_here");</txp:php>

Yes I do need to use PHP
Because I don’t know how to use the same code with the JS SDK yet.
but the problem must be something small and easy to fix.
if it’s works with txp:php so there should not be a problem to work with regular ?php tags and opposite.

Lets ask you this:
how do I convert this code to be right in txp please?

<?php if (!$fbme) { ?>
<div><fb:login-button size="medium">Connect with Facebook</fb:login-button></div>
You've to login to see and manage the comments.
<?php }else{ ?>
<div><fb:login-button size="medium" autologoutlink="true">Logout from Facebook</fb:login-button></div>
You are connected!
<?php } ?>

When I’m converting it to:

<txp:php> if (!$fbme) { </txp:php>
<div><fb:login-button size="medium">Connect with Facebook</fb:login-button></div>
You've to login to see and manage the comments.
<txp:php> }else{ </txp:php>
<div><fb:login-button size="medium" autologoutlink="true">Logout from Facebook</fb:login-button></div>
You are connected!
<txp:php> } </txp:php>

Then I’m getting this error:

Parse error: syntax error, unexpected $end in /textpattern/publish/taghandlers.php(3127) : eval()'d code on line 1

<txp:php> is a tag, and as all tags, it calls a function. As it is function and not normal ending and closing tags of PHP, slicing PHP like that won’t work. You will just end up with invalid PHP as every block is evaluated seperately. There’s a FAQ about the subject: Using PHP code in Textpattern.

Unlike with PHP’s end/closing tags, following won’t work:

<txp:php> if ($foo == $bar) {</txp:php>
	True
<txp:php> }else{ </txp:php>
	False
<txp:php> } </txp:php>

Instead, we have to do:

<txp:php>
	if ($foo == $bar) {
		echo 'True';
	} else {
		echo 'False';
	}
</txp:php>

Thus, with the cut out you provided, we get the consept of:

<txp:php>
	/*
		[...] All the preding code.
	*/
	if (!$fbme) {
		echo 
			'<div><fb:login-button size="medium">Connect with Facebook</fb:login-button></div>'.
			'You've to login to see and manage the comments.';
	 } else {
		echo 
			'<div><fb:login-button size="medium" autologoutlink="true">Logout from Facebook</fb:login-button></div>'.
			'You are connected!';
	}
	/*
		All appending code [...]
	*/
</txp:php>

As the <txp:php> tags do not work on global scope, you neither can transfer data from one block to another, neither you can continue parsing from one block to other. Instead, you need to put everything within one set of tags, or use PHP’s methods to transfer data from function to function.

Hey again, I have the same problem but this time with JS

<script type="text/javascript">
$(document).ready(function() {
var aid = '1063';
var atitle = '<txp:article_custom id="'+aid+'"><txp:title /></txp:article_custom>';
$("#at").append(atitle);
});
</script>
<div id="at"></div>

It’s outputing nothing :/

MattD · 2010-07-08 22:54:39

You can not pass a javascript (client side) variable to a txp tag (server side) in that way. What is aid?

This will work:

<script type="text/javascript">
$(document).ready(function() {
var atitle = '<txp:article_custom id="1063"><txp:title /></txp:article_custom>';
$("#at").append(atitle);
});
</script>
<div id="at"></div>

Ohh…ok, can I mix php into js?
If so I will love to know how please.
or maybe using Ajax? (I really have no idea)

article-id
it’s a variable that I’m getting after a FQL (SQL) Facebook call to they API.
that variable includes an article-id# that I want to use to get the title of the article using article-custom.

Yes of course it is, but unfortunately it not helping me in this case :/

You should understand the difference in javascript and php – JS is run by browser and PHP – by server. You want to get some data from txp:tag – this tags are parsed by server and return data to browser.

If you want to send data from JS to txp:tag (as you tried here) you can use ajax, for example.
