Loading users shouldn't be any different from any other page. The 3,000 individuals I'm storing are not users, though. So I can't confirm for sure.

Hi Webrocker,

I have a site with more than 3,000 pages representing individuals which are displayed in a Lister, and it seems to handle it without issue. What is your limit set to in the Lister's settings? If you try to display all of those pages at once you will definitely have a problem. But if set to ~50 you should be good, and Lister will automatically paginate the results for you.

I find that filtering the pages is still very quick even with all those potential results.

Short on time right now, but to answer your question, Ryan, I am just calling $this->message('message') for each message, the old fashioned way.

To get around this, I'm trying to use the persistent System Notifications. I like the "annoy" flag, but I need a way to make the notifications disappear after they've been shown once. Otherwise the user will get very confused.

I am experiencing an issue with the System Notifications module in 2.6.3. I am using a hook before saveReady() which does a call to PayPal and receives a response. I am adding some notifications based on the response I get from PayPal in order to let the user know whether it was a success or a failure.

For some reason it seems that the extra delay in processing that this introduces results in the notifications not displaying when the page finally reloads. I don't see either my custom notifications or the built in ones confirming the page save.

I've narrowed this issue down to the System Notifications module, since uninstalling it results in the notifications being visible.

I'm wondering if anyone has thoughts on why this would be happening.

Thanks!

Edit: Just to clarify, this is when using runtime Notice objects.

I created a hook on ProcessPageEdit::processSaveRedirect to redirect to an external website when the edit page is saved under certain circumstances. This is working great for regular edit pages, but doesn't work for modal pages (i.e. lister). Is there a way to initiate a redirect from the modal window?

I'm also getting the "Warning: Illegal offset type" line 132 error when I try to output the title after saving a blank. PW 2.6.3

Solved. I just had to give permissions on the language template to the editor role.

When I try this with 2.6.1 I get a blank page with "No items to display yet". None of the languages I have setup in the system show up if I'm logged in as the editor.

I'm a little embarrassed to admit that after several years of working in PW I still don't "get" output formatting in the context of saving pages and fields. 

I understand that when I get the value of a field it is automatically formatted when output formatting is on, and that I can switch this off to get the unformatted value. What I don't understand is why I need to turn off output formatting when I am saving a new value to a page. It's output formatting, not input formatting, right?

Even more befuddling to me is the fact that this often results in a fatal error if I forget to do it, crashing my site. I also have to remember to turn it back on again afterwords, or else I can introduce security flaws into my code.

I'm sure Ryan must have a reason for requiring switching output formatting off when doing a save, but if this is so important and is always required, why isn't it just baked right into the save() method? 

I know the new setAndSave() method now does this for individual fields. It would be great to have a similar method when saving an entire Page.

Neat. You learn something new about ProcessWire every day

As long as the field isn't set to "autojoin", there would be no performance/overhead issue at all, I don't think.

Is it possible to use visibility settings to show a field on a specific page?

$page->myProperty would work, as well as $page->is($selector) or $page->matches($selector). Just $page->find() is searching for "new" pages to be loaded from the db. It's internally changed to $pages->find("has_parent=$page, …") and therefore it's hitting the db. 

Makes sense. I was thinking of things like $page->get('title|parent.title')

Thanks again!

Thanks LostKobrakai, that is a big help.

I wasn't sure about the distinction between when the db is and isn't accessed, since the selector syntax nicely hides that distinction from us

So what you're saying is that I could create a property, but that it would only work on existing PageArrays and not when calling $pages or when using a selector with $page? I'm a little confused as to why it wouldn't work with $page since $page->myMethod() works just fine, but I get why it wouldn't work with $pages.

So does this mean that the run time selector would not be any more efficient than my php loop with an if statement?

What would be the best way to "cache those values in real fields"? Does this mean creating a new field in ProcessWire and writing a hook to update it on save(), or are there other ways of doing that?

I've recently grown fond of using hooks to add custom methods to the Page class to operate on pages of a certain template. On larger projects this helps keep logic out of my template files and tied nicely to the objects they operate on. For example, I have a travel site that has a "departures" template with a field called "group_size". On the front end of the site, I want to show the integer value for the group size as it is stored in the page. However, I have another field called "overflow" which is the additional number of travelers beyond the publicly visible group size who are allowed to book a given trip, to account for anticipated cancelations. I wanted an easy way to know when I should close a given tour, so I created a method called isFull() to house the logic that determines this. I also have getMaxRegistrations() (group_size + overflow), getOpenSlots(), and getPublicOpenSlots(), which all call each other as needed and return different values.

The problem then is when I need to use a selector, I have no way (that I know of) of using these methods in the selector. So instead I need to use a simple selector like $pages->get('template=departure') and then loop through the results and use an if statement on each result (i.e. if($result->isFull())... ) to narrow down the selection to the page(s) I really want.

I don't know enough about how selectors work under the hood to know whether this is the same thing as a selector with a field matching parameter within it, or whether this is much less efficient. 

Is there a better/cleaner/more efficient approach to this?

Clarification... the page didn't allow me to save the self-referential value, but it did appear in the ajax search and allow me to select it from the list. This is a big problem for a site I'm working on at the moment.

To solve this I had to edit InputfieldPageAutocomplete.module and add the following to getAjaxUrl() after the first line of the function:

// Prevent selecting the page this field is on
$thisPageId = $this->input->get->id;
$selector .= ",id!=$thisPageId";

It seems like this is a bug.

Hi valan,

Have you tested the module yet to see if it will work for your needs? I'm not sure I fully understand your question, but it sounds like you want to be able to set the visibility property of a particular page field to "Open when populated and not editable (locked)" but still have the edit link show? Is that correct?

The issue with this and with the other limitation you asked about is the fact that PW doesn't always provide the necessary CSS/JS hooks to be as granular as I would like (strangely, it does for some of the inputfields but not others). Ryan may have fixed this in 2.6, but I haven't had a chance to look at it again. I would like to fix this at some point, if possible!

I found a bug:

        if(!$ptf->has($child->id)) {
            $pp->{$ptf->name}->add($child);
            $pp->of(false);
            $pp->save($ptf->name);
        }

Should be:

        if(!$pp->{$ptf->name}->has($child)) {
            $pp->{$ptf->name}->add($child);
            $pp->of(false);
            $pp->save($ptf->name);
        }

It was re-writing the PageTable items every time, which made it impossible to reorder items.

Ok, this should be fixed.

We should just be able to add white-space: nowrap; to the css.

Or inline-block. I'll take a look at it.

I am having a problem where I need to prevent a Page field that is using autocomplete from allowing me to select the page I am currently editing. I thought that was supposed to be the default behavior, but it is allowing me to select the current page anyway. Since the custom PHP code option doesn't work with autocomplete, I'm a bit at a loss for what to do.

Hey Macrura!

Your post got me going in the right direction. I had to modify it a bit. $config->urls->root->httpUrl returns an error, so I had to use 'https://' . wire('config')->httpHost . '/'.

I'm also looking for links without the http:// and adding that in so that they'll work either way.

Instead of just targeting the assets folder, I'm replacing all instances of relative links ('href="/' or 'src="/') and adding in the site's base URL. It seems to be working.

$base_url = 'https://' . wire('config')->httpHost . '/';
		$placeholders = array('class="align_left"', 'src="/', 'href="/', 'href="www.', 'src="www.');
		$replacements = array('style="float:left;margin-right:20px;"', 'src="' . $base_url, 'href="' . $base_url, 'href="http://www.', 'src="http://www.');  
		$body = str_replace($placeholders, $replacements, $body);

Perfect! Thank you so much for this, adrian!!

( also, I think this should be the core functionality  )

How do you guys deal with images? I am trying to use a CKEditor field for my email body, but all of the images use relative linking

I figured it out. The problem was that I didn't have a Title field for the page I was trying to reference. So how it was working at all, I don't know. I'm now using the Title field to store the company name instead of a separate company_name field. No issues with commas or periods.
