  1. When you add data to a field, the data is not saved to the database. This is the same as when you type the data into the CMS form (before you hit the save button).

    As you know, after changing the content of a field you can save either the whole record or just that field:

    $page->save();
    
    // Or just the field
    $page->save("integer_field");

    But the hook is after Pages::saveReady, so it always runs just before the page is saved to the database – for example, the hook will run after a user hits the Save button but before data is saved to the database.

    So if you use $page->save(), the data will be saved twice, which is unnecessary – though extra safe!

     

  2. I'd suggest hooking on Pages::saveReady.

    So, you could put something like this (not tested) in ready.php:

    $pages->addHookAfter('Pages::saveReady', function($event) {
    
        $page = $event->arguments('page');
            
        if($page->template == "relevant-template") {
    
            $originalValue = $page->date_field;
            
            $newValue = date("oW", strtotime($originalValue)); // or whatever you need to do
            
            $page->set("integer_field", $newValue);
    
        }
    });

    Note that if hooking on saveReady you don't need to save the field or page because the page is about to be saved.

  3. Are the tags in your HTML on separate lines? If so, Firefox will insert a space.

    <p>
    Firefox will add a space at the end of this.
    </p>
    <p>But not at the end of this.</p>

    I haven't noticed this happening in other browsers, though perhaps I've missed something. I have a memory that Firefox has done this for many years at least, but I'm not sure.

    Note that the Inspect tool in Firefox Web Developer Tools re-formats the HTML for easy reading, repositioning tags for many elements, and it removes spaces before tags in at least some cases (which is not helpful and a bit strange in my opinion!), so it's not good for debugging such things. The Page Source tool is more useful.

    I note that the heading "About ProcessWire" does actually have a space at the end in the HTML source. This could be for various reasons - such as a Text Formatter, or simply somebody typing a space!

  4. The Page Protector module makes setting up access to front-end pages easy, and it allows editors (rather than developers) to control access to particular pages – although my guess is this is a feature you won't need.

    However, the module is not necessary for controlling access, and preventing access to pages for users who aren't logged in is quite straightforward without it (see the links in the post I suggested earlier).

    I don't know if there'd be any issues integrating the module with SAML.

    So, it'd be worth considering whether your project would be easier either using or not using Page Protector.

     

     

  5. I've never used the SAML module (or SAML), and I don't know exactly what you're trying to achieve (the level of security you need and so on), so I can't say whether your proposed method is suitable.

    However, do you really need to use SAML for some reason? If not, it's likely that it will be easier if you use PW's user authentication. It's not difficult to work with and is properly secure.

     

  6. If you haven't discovered it already, the parent() function (https://processwire.com/api/ref/page/parent/) used with a selector can be useful for checking if a page has a particular parent - at any level, not just a parent immediately above it. It returns a null page (id = 0) if the page doesn't have a parent that matches the selector.

    For example, if you want to check if a page is a child of a page with id = 123:

    if ($page->parent("id=123")->id != 0) {...

    With other functions, the has_parent selector can be used for similar purposes.

  7. Yes, it can be done using the Google Sheets API (https://developers.google.com/sheets/api). I recommend the PHP Quickstart guide at https://developers.google.com/sheets/api/quickstart/php.

    However, be aware of the usage limits described at https://developers.google.com/sheets/api/limits. These, combined with possible performance limitations, mean that it would probably be best to get the data into PW pages – and not to display the data directly on web pages using API calls from the template file.

    There are various ways you could pull the data into PW pages. One would be to run a Google API call each time the page is saved (for example, hooking on saveReady). Another would be using cron (or the PW module Lazy Cron) for regular updates.

  8. Prepros (https://prepros.io/) works well for me for most things.

    It's (much) less customizable than gulp and similar tools, but makes life simple, and in practice I've rarely wanted it to do something it couldn't - though obviously YMMV. It can slow up when watching large numbers of files, and the FTP could be developed, but although it may not be quite as cool as gulp etc, it saves me a good amount of time!

     

  9. Note that cookies are not secure, so you shouldn't store passwords in them. Even hashed passwords could potentially be used to access your system.

    You'll find lots of advice and ideas for how to go about things via Google (other search engines are available).

    My own basic suggestion would be to use sessions rather than cookies.

    EDIT Just thought. This page might be useful: https://processwire.com/docs/security/sessions/

     

  10. I'd suggest writing a script (https://processwire.com/docs/front-end/include/) to load the data from a CSV or similar, with the data including a URL or path to each image.

    The structure of the data file could be whatever is easiest to handle in the script. It doesn't sound as if what you exported is all that helpful as an example.

    A couple of posts that might be useful:

    https://processwire.com/talk/topic/1153-adding-images-to-a-page-via-the-api/

    https://processwire.com/talk/topic/21183-adding-image-to-page-via-api-page-images-add-solved/

     Note that adding data to the custom fields is straightforward, and just like adding to the image description. For example, if you have a custom field named "caption":

    $addedImage->caption = "Text for the caption.";

  11. If I understand you correctly, you are using a select option field.

    Looping through the selected options is described at https://processwire.com/docs/fields/select-options-fieldtype/#outputting-selected-options-on-a-page

    You could then use if statements to test with something like this:

    if ($media->title == 'facebook' {
        ...

    Or a switch statement might be neater if there are several options:

    switch ($media->title) {
        case 'facebook':
            $soc = 'facebook';
            break;
        case 'twitter':
            ...

     

     

     

  12. The field page2use4homepage will return a null page (id = 0) if no page is selected, which might be confusing things.

    I haven't tested, but I'd suggest using:

    (($page->id == 1) && ($page->page2use4homepage->id != 0))

     

  13. This happened to me once when I moved a site to a new server and accidentally used details for remote access to the first server for dbHost. Took me a while to figure it out!

    There can be various sorts of caching on the server, which may have been set up as a default by the hosting company without you being aware of it. They don't usually cause problems, but they might. What sort of server setup do you have?

  14. I suggest that first you find the error in the HTML as delivered to the browser, and then work out the source of the error.

    View the source of the page or your browser's developer tools ("Inspect"). If you can't work it out, try an HTML validator (e.g. https://validator.w3.org/).

    An <a> element within a <p> is certainly OK.

    With any luck, once you know what the error is, the cause will be reasonably clear. As a total guess, I suspect it'll be something in your template file.
