solved TinyMCE links plugin bug

[Soma]

I just discovered a bug I think.

While tracing down a PW site with lots of assets and pages to scan for all images and links in the RT text fields, I discovered that there's some multiple links that appear to be empty, not visible. So I figured that when inserting a external link in the RT, using the PW link dialog, then afterwards open it again to edit, it then inserts a invisible empty <a href="someurl"></a>" right before the link meant to be changed (which stays untouched).

I'm sure it's not browser specific, but my guess is that the PW inser link plugin need a check. It only seems to fail with manually entered external links. I would consider this urgent to fix soon. I now need to go manually go through all them because it isn't something the client nor me have known. Though with the bootstrap script I wrote to scan whole site and look for such things it's a whole lot easier thanks to the easy as pie API.

Thank for anyone confirming/reproduce this bug.

Soma, I've tried several times to reproduce it but can't. Are there any other factors you can think of? Can you paste in the exact text / context where it's occurring and steps to reproduce? Here's what I tried:

1. Enter some text in the body field, like: test test 123 test test

2. Highlight a word (like the second 'test') and then click link icon.

3. Type in a URL, I did http://processwire.com, and click "insert link".

4. Back in 'body' field, click the link and then click the link icon again to edit the link.

5. Type in a new URL (also tried leaving as-is) and click "insert link" again (also tried "cancel").

6. Click the "HTML" icon to look for extra <a> tags, none found.

Testing in Firefox 8, ProcessWire dev, OS X.

Thanks Ryan for testing. I do "exactly" what you do.

Hmm, not sure what's causing it. I've run a few tests. It didn't happen on a local test install, but on the zueblin.ch website I did. I've removed the bramus css extras plugin to make sure... still same issue. I have 2 TinyMCE fields on same template, so I thought this might be the next one to try. And then I tried to reproduce on my local install and I got same issue suddenly! Can you also try?

The one I was testing with did have 2 TinyMCE fields (body and sidebar). Just went back and tested again, trying to reproduce in both of them, but no luck. I am running 2.2, which uses a newer version of TinyMCE than 2.1. I'm wondering if this issue might already be resolved in 2.2 by that update? Let me know if you have a chance to try this with the latest version and if it still occurs?

Thanks,

Ryan

Ryan, I still get this issue, or related to this:

When I insert a link, everthing is fine, but when editing the link again, it doesn't change the url, in my case it just inserts a new "invisible" link as mentioned above.

BUT also editing an already placed link to check the "open in new window" option, it doesn't do anything, unless I change the URL. I get this no matter what PW version or tinyMCE version... and it get annoying, cause inserting/editing link is some basic feature every CMS should have no problem at all.

The invisible, double link behaviour is something I can't really reproduce in other PW installs other than the one I experience.

Can anyone, please test this out on their install? I think it's something in the link dialog from PW, combined with TinyMCE...

EDIT: looking again little closer in the PW pwlink/editor_plugin.js

if($node.is("a")) anchorText = $node.html();
 else anchorText = selection.getContent();

if(target.length > 0) target = ' target="' + target + '"';
if(url.length) { 
 html = '<a href="' + url + '"' + target + '>' + anchorText + '</a>';
 tinyMCE.execCommand('mceInsertContent', false, html);
 alert(html);
}

There seems to be an issue with the code here. It constructs (if editing a already set link) a link inside a link. So the "html" returned is wrong...

I'll try to find a better solution to this... or if anyone wants to help, I'd appreciate it!

[Soma]

Playing around with it a little I think I've found a solution...

in the pwlink/editor_plugin.js on around line 80 I've did the following

if($node.is("a")) {
anchorText = $node.text();
  //alert("A:"+anchorText);
}
else if($nodeParent.is("a")) {
anchorText = $nodeParent.text();
  //alert("Parent:"+anchorText);
} else {
anchorText = selection.getContent();
  //alert("Text:"+anchorText);
}

So the parent node check was somehow needed, otherwise the whole <a...>text</a> get's returned for the link text if a link is already there selected to edit...

It surprizes me really that nobody has experienced yet.

I would attach the file for you to test but I can't see upload anymore here.

Attached modified js file.

(Also the inserted twice bug I experienced is gone, when I updated to the 3.4.7 TinyMCE)

Soma, I actually did run into the issue where I couldn't change a URL for an existing link recently. It happened on a client's site. Then I couldn't reproduce it locally, but clearly there's an issue. Thanks for your work in helping to resolve this. If you think it's ready, I will go ahead and commit your solution to the source (unless you prefer to do a pull request). Or let me know if you think more testing is needed here and I will plan to work on it as soon as possible.

I have similar issues on my dev. site (running xammp). I can't change existing links, but have to delete the link first and than create a new one.

I also ran into the empty link issue.

For some reason I haven't reported the issue. I think because I blamed it on Windows running Xampp.

I'll replace the file on my system and will test it.

Great thanks formmailer for the testing! Never blame it on something you don't know!

[ryan]

Thanks Soma, tested here and all seems to work well! Thanks for resolving this issue.

[formmailer]

I replaced /wire/modules/Inputfield/InputfieldTinyMCE/plugins/pwlink/editor_plugin.js with the Soma's version, but for me it looks like the issues are still there.

Just got an empty link and it isn't possible to edit an existing link. Instead I have to delete the link, and add a new one.

Thanks for testing. Can you try clearing cache again? I also once thought it isn't working but then it suddenly worked.

[formmailer]

I cleared the PW cache before testing, but didn't clear the browser cache. Will try that later today.

[formmailer]

Soma, you were absolutely right. Clearing the browser cache solved te problem.

Thanks!
