[Plugin: WP-Table Reloaded] PHP Extensions dont show variables

Hi Linchen,

thanks for your question.

You have to be careful with variables here: Where (in what scope) does the $hallo variable exist? Was it defined directly inside the table cell? Or is defined outside of the cell? In that case, you will need to make it global, with a statement like this:

global $hallo;

at the beginning of your cell.

Also, there is an important thing that you have to keep in mind when using the PHP Extension in WP-Table Reloaded 1.9.1:
You must turn of table output caching for all tables that use PHP (otherwise your PHP code will only be executed once daily), by unchecking the corresponsing checkbox on the table’s “Edit” screen.

Hi,

thanks for that description.

Now I’m a little bit confused 🙂 So, you are having a plugin to use PHP in posts, and my Extension to use PHP in table cells, right?

In the code you posted, you are using a Shortcode inside of PHP. This will never work though, as Shortcodes have nothing to do with PHP. You should actually get a PHP parse error from that.
Did you mean

<?php
include_once('include.php');
echo "$hallo";
?>
[table id=8 /]

But then, what is the PHP code in the table cells of table 8?

You might also need to use include() instead of include_once(), so that your file is actually included every time. Otherwise the variables will not exist in the function’s scope.

Hi,

ok, thanks for the clarification.

Please try this:
include.php

<?php $hallo="hallo";?>

widget (no PHP here!)

[table id=8 /]

cell (with the PHP extension for WP-Table Reloaded enabled)

<?php
include( 'include.php' );
echo $hallo;
?>

(Note: I’m not sure right now, where the include.php needs to be located, so that the include call can find it. You might need to experiment with some “../..” in front of the file name, or use an absolute path.)
