Description
I've installed and configured Imagebrowser to use the WYSIWYG-API with FCK-Editor 2.6.5 on drupal 6.14. Everything works fine, except the final step. I created a new input format that uses only the Image Browser Filter. Than I configured the FCKEditor Profile to show only the button for the image browser.
So I can create a new page and choose my new input format. The FCK comes up with the imagebrowser button. I hit the button and the imagebrowser shows up with my images. I can choose an image and set all options. But finally when I hit 'Insert', nothing happens, the image browser stays open and no image is inserted. 'Cancel', 'Close' and 'Delete' do what they are supposed to do, but 'Insert' does not work.

Getting any javascript errors?

Hi
See this thread:
http://drupal.org/node/564822

That is a good hint! Currently I'm using PHP5.1, so this might be the cause. I will update my PHP and report if it fixes this issue.
#4
Yes, that solves it. I updated my php to 5.2.6 and now it works like a charme.
So I think the requirements in README.txt should claim that only PHP >= 5.2 is supoorted (json_encode() is available).

Thanks for flagging this. I might write a custom json_encode() to do the job.

This is from the php.net documentation page of json_encode, a substitute:
<?php
if (!function_exists('json_encode'))
{
function json_encode($a=false)
{
if (is_null($a)) return 'null';
if ($a === false) return 'false';
if ($a === true) return 'true';
if (is_scalar($a))
{
if (is_float($a))
{
// Always use "." for floats.
return floatval(str_replace(",", ".", strval($a)));
}
if (is_string($a))
{
static $jsonReplaces = array(array("\\", "/", "\n", "\t", "\r", "\b", "\f", '"'), array('\\\\', '\\/', '\\n', '\\t', '\\r', '\\b', '\\f', '\"'));
return '"' . str_replace($jsonReplaces[0], $jsonReplaces[1], $a) . '"';
}
else
return $a;
}
$isList = true;
for ($i = 0, reset($a); $i < count($a); $i++, next($a))
{
if (key($a) !== $i)
{
$isList = false;
break;
}
}
$result = array();
if ($isList)
{
foreach ($a as $v) $result[] = json_encode($v);
return '[' . join(',', $result) . ']';
}
else
{
foreach ($a as $k => $v) $result[] = json_encode($k).':'.json_encode($v);
return '{' . join(',', $result) . '}';
}
}
}
?>
