It's occurred to me that adding to this existing thread might have been the better option for seeking a solution to my problem.

I've already created a new thread so I wonder if it's ok to post a link to it here in case anyone who might know the answer will be more likely to see it here...

I think there might be still better places to ask. :)

Table is a Pro field with it's own dedicated support sub-forum.

And the feature you are describing is not a feature of Hanna Code but rather a feature of the Hanna Code Helper module.

Hi all,

I'm struggling with a problem which is more a PHP issue than one of Hanna Code.

<?php
?>
<audio controls>
	<source src='<?= $audiofile?>' type='audio/mp3'> 
</audio>

This little HC  works fine when used in a textarea/CKEditor field like this:

[[audio file="/site/assets/files/1234/foo.mp3"]]

Now I wanted to make it flexible and enable the editor user to insert the path to any mp3 file (stored on some page in a field "mp3" of type File, allowed file extension mp3). 

In the HC Attributes I set a default value for $file, defining   file=LINK . Now the editor, inserting the HC using the HannaCodeHelper Module, gets

[[audio file="LINK"]]

The aimed workflow for the editor user was: Double click on LINK to mark it and using the Link button of the CKEditor to choose the wanted file from the wanted page. Obviously, the value created by CKE had to undergo some treatment.

Of course it's a link from which I had to extract the value of the href attribute (here  /site/assets/files/1122/bar.mp3) , but because of the double quotes from   [[audio file="LINK"]]  it would become

"<a href="/site/assets/files/1234/foo.mp3">"

where the second  "  would terminate the string. I tried string functions str_replace(), strstr() etc. but to no avail.
Perhaps I could have used Javascript, but I wanted to find a PHP solution.

Could anyone help on that?

@ottogal

An easy solution would be to change...

[[audio file="LINK"]]

...to...

[[audio file='LINK']]

If you want Hanna Code Helper to insert single quotes around attributes I think you'll have to modify the module code. Change line 124 to:

$attrs .= " $attrName='$attrValue'";

You can use SimpleXML in your Hanna Code to get the href from the link:

$a = new SimpleXMLElement($file);
$path = $a['href']->__toString();

Good find, thank you!

After this change even my simple use of the function strstr() works -  to crop the string on both ends, setting free the href attribute value:

<?php
$f = (string) $file;
$f = strstr($f,'/site');
$audiofile = strstr($f,'">',true);
?>
<audio controls>
	<source src='<?= $audiofile?>' type='audio/mp3'> 
</audio>

Your second hint to use SimpleXMLElement() of course is a cleaner way to do it:

<?php
$a = new SimpleXMLElement($file);
$audiofile = $a['href']->__toString();
?>
<audio controls>
	<source src='<?= $audiofile?>' type='audio/mp3'> 
</audio>

Didn't know this class before - so again I learnt something new. Thanks a lot again!

Good day.
I really liked the Hana Code Insert plugin. But I was faced with the following problem. In WordPress platform there are 5 roles: Administrator, Editor, Author, Contributor, Subscriber.
I want only the Administrator could work with this plugin.
How to limit access to this plugin for role Contributor ?
Sorry, for my bad English.

Check out the hanna specific permissions and only assign them to the contributor role.

If I understand correctly, you need to edit the code in the plugin ?

No - just go to your PW Access > Roles menu and assign the relevant hanna permissions to the appropriate roles.

I just re-read your question and see that you actually only want the codes editable  by the administrator role. By this do you mean the PW superuser role? By default, only the superuser should be able to view/edit hanna codes.

I have installed wordpress version 4.5.3.
Please tell me where I need to go and what to do?
Please explain the steps
Or show a screenshot

I think you're in the wrong place - this is the support forum for ProcessWire, not Wordpress!

ProcessWire also has a hanna code plugin - I think that is your confusion, but since you are here, maybe you should stay :)

I answered my own question in the next post:

$my_pages = $pages->getById([1086,1021,1053,1018]);

The situation @Wanze replied to is a little different - not an order of page IDs but an order of values to match a field against.

I like this module, I used similar plugin in Wordpress before I switched to PW, so I was happy to find it.

Regarding the code editor, a helper module would be very useful which could save and reload the scrolling and cursor position when saving the code, so I could continue the editing where I left it.
I'm not sure where, but I found something similar, but I don!t remember exactly. I tried to search in Google again and in this forum also, but no success. Maybe it was a different editor ...

Can anyone suggest a solution?
Thanks!

I use that technique in the Console Panel of the TracyDebugger module - it's pretty easy to implement by storing the current position in LocalStorage or cookie. Perhaps you could send Ryan a PR with the added functionality?

I checked TracyDebugger and I like it, thanks for the suggestion!
As I see, it uses Ace editor also, so your solution can be implemented in the Hanna code modul too. Can you give me more details, how you did that?

Hi all,

distracted for a while by other (bigger) problems, I now came back to the situation discussed here in this thread in october:

On 27.10.2016 at 3:01 PM, ottogal said:

<?php
$f = (string) $file;
$f = strstr($f,'/site');
$audiofile = strstr($f,'">',true);
?>
<audio controls>
	<source src='<?= $audiofile?>' type='audio/mp3'> 
</audio>

Your second hint to use SimpleXMLElement() of course is a cleaner way to do it:


<?php
$a = new SimpleXMLElement($file);
$audiofile = $a['href']->__toString();
?>
<audio controls>
	<source src='<?= $audiofile?>' type='audio/mp3'> 
</audio>

 

For my Hanna Code call    [[mp3 audio='LINK']]    now I have this Hanna Code (mp3.php):  (and all works fine - :) )

<?php
$a = new SimpleXMLElement($audio);
$pagelink = $a['href']->__toString();
$pagename = basename($pagelink);
$ap = $pages->get("template=audio,parent=audiopool,name=$pagename");
$link = $ap->mp3->url;
?>
	<div class='block'>
		<audio  controls width='400'>
			<source src='<?= $link ?>' type='audio/mp3'> 
		</audio>
	</div>
	<p><?= $pagename ?></p>

But when I open the Hanna Code in the editor and click the button "Save & Test", I get the following messages:

Quote

Warning: SimpleXMLElement::__construct() [simplexmlelement.--construct]: Entity: line 1: parser error : Start tag expected, '<' not found in ....../site/assets/cache/HannaCode/mp3.php on line 4

Warning: SimpleXMLElement::__construct() [simplexmlelement.--construct]: LINK in ....../site/assets/cache/HannaCode/mp3.php on line 4

Warning: SimpleXMLElement::__construct() [simplexmlelement.--construct]: ^ in ....../site/assets/cache/HannaCode/mp3.php on line 4


ProcessWire: ProcessHannaCode: String could not be parsed as XML
......

The line number refers to the file  ....../site/assets/cache/HannaCode/mp3.php where  the line

Quote

if(!defined("PROCESSWIRE")) die("no direct access");

and a blank line are prepended - so  the line in question is, of course: 

Quote

$a = new SimpleXMLElement($audio);

What is wrong with the code, and how can I get rid of these Warnings?

Thankful for some clarification:

ottogal

I think that's because when you use your Hanna tag in CKEditor your audio attribute is (or should be) valid link markup, e.g. <a href="/some/url/">LINK</a>

But in the Hanna Code test tab the attribute is not a valid link but simply the string "LINK" which cannot be parsed by SimpleXML. So probably nothing to worry about, but if the error message is a concern you can do some simple check to see if the attribute looks like it will be a link. For example, at the top of your Hanna code:

if(substr($audio, 0, 2) !== '<a') return;

      LogMaintenance
      A simple ProcessWire module to give some maintenance control over log files. I found myself often having lots of log files for different things that can grow more or less quickly to a size where they can be difficult to maintain. The built in Logger of PW does a good job of giving you the possibility to delete or prune logs. But it has to be done manually and sometimes a log grows into millions of lines, which makes it often impossible to even prune it as it's too large.
      LogMaintenance uses LazyCron to run the maintenance task and there's several settings you can setup on a global or per log basis.
      Archive: will create zip files for each log file in logs/archive/ folder and add the log each time the maintenance is run to a subfolder containing the datetime.
      Lines: keeps logs to a certain number of lines 
      Days: keeps the log to a certain number of days
      Bytes: keeps the log to a certain amount of bytes
      Each setting is checked from top down, the first setting to contain something is used. So if you check the "Archive" option, all other settings are ignored and logs are archived everytime the LazyCron is executed. If you want to keep your logs to a certain amount of bytes just leave all other settings to 0 or blank.
      Per Log Settings
      There's a textarea that you can use to setup a config for a specific log file one per line. All the logs you define here ignore the global settings above. The syntax for the settings is:
      logname:[archive]:[lines]:[days]:[bytes] 
      errors:1:0:0:0 // would archive the errors log messages:0:10000:0:0 // will prune the errors log to 10000 lines  
      The module can be found on github for you to check out. It's still fresh and I'm currently testing.

      Fieldtype Page IDs is a third party Fieldtype that, simply put, stores Page references as integers (Page IDs).
      This fieldtype was built as a quick and dirty workaround for Page Reference fields' inability handle self-references due to circular reference issues. A project I've been working on for a while now includes a combination of RepeaterMatrix content blocks and tagging/categorization system that would've resulted in a lot of duplicate pages (and plenty of unnecessary manual work for content editors) had I used built-in Page Reference fields, and thus a new Fieldtype felt like the most sensible approach.
      Fieldtype Page IDs was designed to be loosely compatible with Page References in order to make conversions between the two feasible, but it is quite limited feature wise:
      largely due to the fact that stored values are actually just integers with no connection to Pages whatsoever some advanced selectors and related features are not supported, and page values can't be directly accessed configuration settings are limited to the bare essentials (selector string and Inputfield class) only a handful of Inputfields (AsmSelect, Checkboxes, Text) are (currently) supported Anyway, in case you need to store Page IDs (and Page IDs only) and are happy with the limitations mentioned above, feel free to give this Fieldtype a try. It has been working fine for me in one particular project, but hasn't been tested that much, so please tread carefully – and let me know if you run into any issues.

      This is a lightweight alternative to other newsletter & newsletter-subscription modules.
      You can find the Module in the Modules directory and on Github
      It can subscribe, update, unsubscribe & delete a user in a list in Mailchimp with MailChimp API 3.0. It does not provide any forms or validation, so you can feel free to use your own. To protect your users, it does not save any user data in logs or sends them to an admin.
      This module fits your needs if you...
      ...use Mailchimp as your newsletter / email-automation tool ...want to let users subscribe to your newsletter on your website ...want to use your own form, validation and messages (with or without the wire forms) ...don't want any personal user data saved in any way in your ProcessWire environment (cf. EU data regulation terms) ...like to subscribe, update, unsubscribe or delete users to/from different lists ...like the Mailchimp UI for creating / sending / reviewing email campaigns *I have only tested it with PHP 7.x so far, so use on owners risk
      EDIT:
      I've updated the module to 0.0.4. I removed the instructions from this forum, so I don't have to maintain it on multiple places. Just checkout the readme on github 🙂
      If you have questions or like to contribute, just post a reply or create an issue or pr on github.

      WHY?
      This module was built to fill the gap between simple $pages->find() operations and complex SQL queries.
      The problem with $pages->find() is that it loads all pages into memory and that can be a problem when querying multiple thousands of pages. Even $pages->findMany() loads all pages into memory and therefore is a lot slower than regular SQL.
      The problem with SQL on the other hand is, that the queries are quite complex to build. All fields are separate tables, some repeatable fields use multiple rows for their content that belong to only one single page, you always need to check for the page status (which is not necessary on regular find() operations and therefore nobody is used to that).
      In short: It is far too much work to efficiently and easily get an array of data based on PW pages and fields and I need that a lot for my RockGrid module to build all kinds of tabular data.
