  1. I'm pretty sure I've seen something similar happen when nesting an <a></a> inside another <a></a> - looks "fine" in page source but the browser attempts to escape them or something and it displays differently in the inspector. Steps I would go through is to to replace each var value with a blank string, go through each methodically, or maybe remove each <a></a> and add each one back in to identify which one is triggering it. You might find it completely unrelated to the above, but it'll get you closer to the source of the issue! PS - Grammarly browser extension and CKEditor 4 don't mix well. Had to ask a number of clients and colleagues to disable it so they can actually save content.
  2. Hi, The main breaking change with my version of the module is that Cc/Bcc is ignored if batch mode is set to on. Seemed absurd to me that an email sent to multiple addresses individually would be sent each time to any cc/bcc addresses set. The latest version is compatible with 2.7 onwards. I implemented fallbacks for things (e.g. textTools) not present in the 2 branch. It also has more features and I've been using it in production without issue since I first posted it. However, I've not been using it for much more than sending simple emails. It's fully tested though 🙂 I'd recommend using it if starting a new project, but I'm reluctant for it to be the main directory module as any users upgrading could encounter problems with their existing implementation. They'd be easy to fix, but that's not the point. I don't use any of the Pro modules that it integrates with (FormBuilder, ProMailer), and wouldn't want to interrupt "power" users of these. Perhaps my version should have a different name? WireMailMailgun3 and I could remove the fallbacks for the 2 branch? Cheers, Chris
  3. @netcarver- I've got it automatically placed after the <title> element now, if that element exists (which it should!). @horst - I've added a renderMeta method to allow for manual outputting of the meta tag in the <head>. If this is used, it shouldn't output automatically.
  4. Hi @alexmercenary - aye I didn't have the "uk-img" enabled by way of the data-src attribute. I've fixed that now, should be on the repo. Worth noting that enabling uk-img changes the src attribute to data-src, and adds a src attribute with a blank pixel: src='data:image/gif;base64,R0lGODlhAQABAIAAAP///wAAACH5BAEAAAAALAAAAAABAAEAAAICRAEAOw=='. The src attribute is required for valid HTML5, so I've been in the habit of adding this blank pixel for this purpose.
  5. Hi @netcarver, Thanks for the feedback - I'll have a look at this soon and see if I can get it placed better. Cheers, Chris
  6. Hi @alexmercenary, "uk-img" doesn't validate as HTML5. I always use the data- prefix for this reason, it's one of the ways to use UIkit components: https://getuikit.com/docs/javascript#component-usage. As for the srcset attribute - I think they've updated the docs here, they had it without the data- prefix until recently. I'll update this when I get a chance - the current implementation will still work. Cheers, Chris
  7. I've spent the last while experimenting with srcset implementation - and PageimageSrcset is the result: PageimageSrcset Provides configurable srcset and sizes properties/methods for Pageimage. Overview The main purpose of this module is to make srcset implementation as simple as possible in your template code. It does not handle images rendered in CKEditor or similar fields. For an introduction to srcset and sizes, please read this Mozilla article about responsive images. Pageimage::srcset() // The property, which uses the set rules in the module configuration $srcset = $image->srcset; // A method call, using a set rules string // Delimiting with a newline (\n) would also work, but not as readable $srcset = $image->srcset("320, 480, 640x480 768w, 1240, 2048 2x"); // The same as above but using an indexed/sequential array $srcset = $image->srcset([ "320", "480", "640x480 768w", "1240", "2048 2x", ]); // The same as above but using an associative array // No rule checking is performed $srcset = $image->srcset([ "320w" => [320], "480w" => [480], "768w" => [640, 480], "1240w" => [1240], "2x" => [2048], ]); // Use the default set rules with portrait images generated for mobile/tablet devices $srcset = $image->srcset(true); // Return the srcset using all arguments $srcset = $image->srcset("320, 480, 640x480 768w, 1240, 2048 2x", [ "portrait" => "320, 640", ]); // The set rules above are a demonstration, not a recommendation! Image variations are only created for set rules which require a smaller image than the Pageimage itself. On large sites this may still result in a lot of images being generated. If you have limited storage, please use this module wisely. Portrait Mode In many situations, the ratio of the image does not need to change at different screen sizes. However, images that cover the entire viewport are an exception to this and are often the ones that benefit most from srcset implementation. The main problem with cover images is that they need to display landscape on desktop devices and portrait when this orientation is used on mobile and tablet devices. You can automatically generate portrait images by enabling portrait mode. It is recommended that you use this in combination with Pageimage::focus() so that the portrait variations retain the correct subject. The generated variations are HiDPI/Retina versions. Their height is determined by the portrait ratio (e.g. 9:16). Variations are always generated, regardless of whether the original image is smaller. Upscaling is disabled though, so you may find that some variations are actually smaller than they say they are in their filename. The sizes attribute should be used when portrait mode is enabled. Pageimage::sizes will return (orientation: portrait) and (max-width: {maxWidth}px) 50vw by default, which handles the use of these images for retina devices. The maximum width used in this rule is the largest set width. Pageimage::sizes() There is no option to configure default sizes because in most cases 100vw is all you need, and you do not need to output this anyway as it is inferred when using the srcset attribute. You can use the method for custom sizes though: // The property $sizes = $image->sizes; // Returns 100vw in most cases // Returns '(orientation: portrait) and (max-width: {maxWidth}px)50vw' if portrait mode enabled // A method call, using a mixture of integer widths and media query rules // Integer widths are treated as a min-width media query rule $sizes = $image->sizes([ 480 => 50, "(orientation: portrait) and (max-width: 640px)" => 100, 960 => 25, ]); // (min-width: 480px) 50vw, (orientation: portrait) and (max-width: 640px) 100vw, (min-width: 960px) 25vw // Determine widths by UIkit 'child-width' classes $sizes = $image->sizes([ "uk-child-width-1-2@s", "uk-child-width-1-3@l", ]); // (min-width: 640px) 50vw, (min-width: 1200px) 33.33vw // Determine widths by UIkit 'width' classes $sizes = $image->sizes([ "uk-width-1-2@m", "uk-width-1-3@xl", ]); // (min-width: 960px) 50vw, (min-width: 1600px) 33.33vw // Return the portrait size rule $sizes = $image->sizes(true); // (orientation: portrait) and (max-width: {maxWidth}px) 50vw // The arguments above are a demonstration, not a recommendation! Pageimage::render() This module extends the options available to this method with: srcset: When the module is installed, this will always be added, unless set to false. Any values in the formats described above can be passed. sizes: Only used if specified. Any values in the formats described above can be passed. uk-img: If passed, as either true or as a valid uk-img value, then this attribute will be added. The srcset attribute will also become data-srcset. Please refer to the API Reference for more information about this method. // Render an image using the default set rules echo $image->render(); // <img src='image.jpg' alt='' srcset='{default set rules}'> // Render an image using custom set rules echo $image->render(["srcset" => "480, 1240x640"]); // <img src='image.jpg' alt='' srcset='image.480x0-srcset.jpg 480w, image.1240x640-srcset.jpg 1240w'> // Render an image using custom set rules and sizes // Also use the `markup` argument echo $image->render("<img class='image' src='{url}' alt='Image'>", [ "srcset" => "480, 1240", "sizes" => [1240 => 50], ]); // <img class='image' src='image.jpg' alt='Image' srcset='image.480x0-srcset.jpg 480w, image.1240x640-srcset.jpg 1240w' sizes='(min-width: 1240px) 50vw'> // Render an image using custom set rules and sizes // Enable uk-img echo $image->render([ "srcset" => "480, 1240", "sizes" => ["uk-child-width-1-2@m"], "uk-img" => true, ]); // <img src='image.jpg' alt='' data-uk-img data-srcset='image.480x0-srcset.jpg 480w, image.1240x640-srcset.jpg 1240w' sizes='(min-width: 960px) 50vw'> // Render an image using portrait mode // Default rule sets used: 320, 640, 768, 1024, 1366, 1600 // Portrait widths used: 320, 640, 768 // Original image is 1000px wide // Not possible to use portrait mode and custom sets or portrait widths in render() // Sizes attribute automatically added echo $image->render(["srcset" => true]); // <img src='image.jpg' alt='' srcset='image.320x569-srcset-hidpi.jpg 320w, image.640x1138-srcset-hidpi.jpg 640w, image.768x1365-srcset-hidpi.jpg 768w, image.jpg 1024w' sizes='(orientation: portrait) and (max-width: 768px) 50vw'> Configuration To configure this module, go to Modules > Configure > PageimageSrcset. Set Rules These are the default set rules that will be used when none are specified, e.g. when calling the property: $image->srcset. Each set rule should be entered on a new line, in the format {width}x{height} {inherentwidth}w|{resolution}x. Not all arguments are required - you will probably find that specifying the width is sufficient for most cases. Here's a few examples of valid set rules and the sets they generate: Set Rule Set Generated Arguments Used 320 image.320x0-srcset.jpg 320w {width} 480x540 image.480x540-srcset.jpg 480w {width}x{height} 640x480 768w image.640x480-srcset.jpg 768w {width}x{height} {inherentwidth}w 2048 2x image.2048x0-srcset.jpg 2x {width} {resolution}x How you configure your rules is dependent on the needs of the site you are developing; there are no prescriptive rules that will meet the needs of most situations. This article gives a good overview of some of the things to consider. When you save your rules, a preview of the sets generated and an equivalent method call will be displayed to the right. Invalid rules will not be used, and you will be notified of this. Portrait Mode Set Widths A comma limited list of widths to create HiDPI/Retina portrait variations for. Crop Ratio The portrait ratio that should be used to crop the image. The default of 9:16 should be fine for most circumstances as this is the standard portrait ratio of most devices. However, you can specify something different if you want. If you add a landscape ratio, it will be switched to portrait when used. Any crops in the set rules ({width}x{height}) are ignored for portrait mode variations as this ratio is used instead. UIkit Widths If your website theme uses UIkit, you can pass an array of UIkit width classes to Pageimage::sizes to be converted to sizes. The values stored here are used to do this. If you have customised the breakpoints on your theme, you should also customise them here. Please note that only 1- widths are evaluated by Pageimage::sizes, e.g. uk-width-2-3 will not work. Remove Variations If checked, the image variations generated by this module are cleared on Submit. On large sites, this may take a while. It makes sense to run this after you have made changes to the set rules. Image Suffix You will see this field when Remove Variations is checked. The value is appended to the name of the images generated by this module and is used to identify variations. You should not encounter any issues with the default suffix, but if you find that it conflicts with any other functionality on your site, you can set a custom suffix instead. Debug Mode When this is enabled, a range of information is logged to pageimage-srcset. PageimageSrcsetDebug.js is also added to the <head> of your HTML pages. This will console.log a range of information about the images and nodes using srcset on your page after a window.onresize event is triggered. This can assist you in debugging your implementation. The browser will always use the highest resolution image it has loaded or has cached. You may need to disable browser caching to determine whether your set rules are working, and it makes sense to work from a small screen size and up. If you do it the other way, the browser is going to continue to use the higher resolution image it loaded first. UIkit Features This module implements some additional features that are tailored towards UIkit being used as the front-end theme framework, but this is not required to use the module. Installation Download the zip file at Github or clone the repo into your site/modules directory. If you downloaded the zip file, extract it in your sites/modules directory.

  8. Hello, I thought it might be useful to post a CSP I've recently deployed using this module. Every site is different - there's no prescriptive policy and that's the main caveat here. This is for a site with an embedded Shopify store, an Issuu embed, a Google Tour embed and Google Maps implementation (JS API). It also uses Font Awesome 5 from their CDN, jQuery from CDNJS, and some Google Fonts. It also has TextformatterVideoEmbed installed alongside its extended options module. default-src 'none'; script-src 'self' cdnjs.cloudflare.com *.google.com *.gstatic.com *.googleapis.com www.google-analytics.com www.googletagmanager.com e.issuu.com sdks.shopifycdn.com; style-src 'self' 'unsafe-inline' cdnjs.cloudflare.com *.googleapis.com use.fontawesome.com; img-src 'self' data: *.google.com *.googleapis.com *.gstatic.com *.ggpht.com www.google-analytics.com www.googletagmanager.com brand.nbcommunication.com *.shopify.com sdks.shopifycdn.com; connect-src 'self' www.google-analytics.com ocean-kinetics.myshopify.com; font-src 'self' fonts.gstatic.com use.fontawesome.com; object-src 'self'; media-src 'self' data:; manifest-src 'self'; frame-src www.google.com www.youtube.com www.youtube-nocookie.com player.vimeo.com w.soundcloud.com e.issuu.com; form-action 'self'; base-uri 'self' The Shopify embed script and Google Analytics initialisation have been moved into script files so there are no inline scripts at all. The script-src 'unsafe-inline' directive is an obstacle to getting that A+ on Observatory. Google Analytics is also a bit of an impediment to getting a top-drawer score, as its script doesn't use SRI. However, there is a reason for that as I understand it - it is a script that just loads other scripts so SRI implementation would just be token, it wouldn't actually be improving security. Still, it is possible to get A+ without dealing with this. It would be great to get some discussion going on CSP implementation - I'm only a few weeks in myself, so have much to learn! Cheers, Chris NB

  10. Please let me know how you find it - this module is really just a result of looking into it the past two weeks to try and get an A+ on Mozilla Observatory (did it! 😆) so I'd really appreciate any feedback!
  11. Wondering how to get that A+ rating on Mozilla Observatory? Now you can with ⭐⭐⭐MarkupContentSecurityPolicy⭐⭐⭐ Of course, MarkupContentSecurityPolicy does not guarantee an A+ rating, but it does help you implement a Content Security Policy for your ProcessWire website. Markup Content Security Policy Configure and implement a Content Security Policy for all front-end HTML pages. This module should only be used in production once it has been fully tested in development. Implementing a Content Security Policy on a site without testing will almost certainly break something! Overview Website Security Auditing Tools such as Mozilla Observatory will only return a high score if a Content Security Policy is implemented. It is therefore desirable to implement one. A common way of adding the Content-Security-Policy header would be to add it to the .htaccess file in the site's root directory. However, this means the policy would also cover the ProcessWire admin, and this limits the level of security policy you can add. The solution is to use the <meta> element to configure a policy, for example: <meta http-equiv="Content-Security-Policy" content="default-src 'self'; img-src https://*; child-src 'none';">. MarkupContentSecurityPolicy places this element with your configured policy at the beginning of the <head> element on each HTML page of your site. There are some limitations to using the <meta> element: Not all directives are allowed. These include frame-ancestors, report-uri, and sandbox. The Content-Security-Policy-Report-Only header is not supported, so is not available for use by this module. Configuration To configure this module, go to Modules > Configure > MarkupContentSecurityPolicy. Directives The most commonly used directives are listed, with a field for each. The placeholder values given are examples, not suggestions, but they may provide a useful starting point. You will almost certainly need to use 'unsafe-inline' in the style-src directive as this is required by some modules (e.g. TextformatterVideoEmbed) or frameworks such as UIkit. Should you wish to add any other directives not listed, you can do so by adding them in Any other directives. Please refer to these links for more information on how to configure your policy: https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Security-Policy https://scotthelme.co.uk/content-security-policy-an-introduction/ https://developers.google.com/web/fundamentals/security/csp/ Violation Reporting Because the report-uri directive is not available, when Violation Reporting is enabled a script is added to the <head>which listens for a SecurityPolicyViolationEvent. This script is based on https://developer.mozilla.org/en-US/docs/Web/API/SecurityPolicyViolationEvent and POSTs the generated report to ?csp-violations=1. The module then logs the violation report to csp-violations. Unfortunately, most of the violations that are reported are false positives, and not actual attempts to violate the policy. These are most likely from browser extensions and are not easy to determine and filter. For this reason, there is no option for the report to be emailed when a policy is violated. Instead, you can specify an endpoint for the report to be sent to. This allows you to handle additional reporting in a way that meets your needs. For example, you may want to log all reports in a central location and send out an email once a day to an administrator notifying them of all sites with violations since the last email. Retrieving the Report To retrieve the report at your endpoint, the following can be used: $report = file_get_contents("php://input"); if(!empty($report)) { $report = json_decode($report, 1); if(isset($report) && is_array($report) && isset($report["documentURI"])) { // Do something } } Debug Mode When this is enabled, a range of information is logged to markup-content-security-policy. This is probably most useful when debugging a reporting endpoint. Additional .htaccess Rules To get an A+ score on Mozilla Observatory, besides using HTTPS and enabling the HSTS header, you can also place the following prior to ProcessWire's htaccess directives: Header set Content-Security-Policy "frame-ancestors 'self'" Header set Referrer-Policy "no-referrer-when-downgrade" Installation Download the zip file at Github or clone the repo into your site/modules directory. If you downloaded the zip file, extract it in your sites/modules directory. In your admin, go to Modules > Refresh, then Modules > New, then click on the Install button for this module. ProcessWire >= 3.0.123 is required to use this module.
  12. I've been doing a little rejigging of our default htaccess file after yesterday's dev release, and trying to understand Section 18 a bit better too... In section 18 we use a rule based on what is outlined here: https://processwire.com/blog/posts/optimizing-404s-in-processwire/ RewriteCond %{REQUEST_URI} !\.(jpg|jpeg|gif|png|ico|webp|svg|php|cgi|pl|asp|rar|zip)$ [NC] This is entered after the existing section 18 rules, which are left commented out. After the end of ProcessWire's htaccess rules we have: <FilesMatch "\.(jpg|jpeg|gif|png|ico|webp|svg|php|cgi|pl|asp|rar|zip)$"> ErrorDocument 404 "The requested file was not found. </FilesMatch> Without that rule, I get the ProcessWire 404 page when accessing a non-existent file matching one of those types. On a different htaccess-related note, I recommend the 6G htaccess Firewall https://perishablepress.com/6g/. We have this at the start of our default .htaccess file, followed by: ErrorDocument 403 "Sorry, you are not permitted to access this resource. The only issue I've come across after a few years of use is with the autocomplete Page field, when using OR selectors (e.g. template=home|default). I wrote this hook as a remedy: <?php // Replace pipes (|) with %7C in PageAutocomplete data-url attribute // This gets around 6G htaccess rules which disallows pipes in urls $wire->addHookAfter("InputfieldPageAutocomplete::render", function(HookEvent $event) { $out = $event->return; if(strpos($out, "data-url") === false) return; $url = explode("'", ltrim(explode("data-url=", $out)[1], "'"))[0]; $event->return = str_replace($url, str_replace(" ", "+", str_replace("|", "%7C", $url)), $out); }); Cheers, Chris
  13. Hey, Launched a site today with a form that sends attachments and it turned out that our production server doesn't have mime_content_type() 🙁 https://github.com/chriswthomson/WireMailMailgun/pull/17 I've added a private method getMimeType() which checks first for mime_content_type(), then finfo_open(), then falls back to inferring based on file extension if neither exist. This is based on https://www.php.net/manual/en/function.mime-content-type.php#87856 and https://gist.github.com/Erutan409/8e774dfb2b343fe78b14#file-mimetype-php Also, a WireException is now thrown if an attachment has been added using WireMail::attachment() but curl_file_create() doesn't exist. Cheers, Chris
  14. Hi @Schwab - I'm not sure how this can be done, although given that there are a number of WireMail extension modules out there, I'm sure it must be possible and discussed previously. Might be worth having a look through the threads for WireMail SMTP etc to see if there is any info there. I'm assuming this is @Macrura's version on the module repo - these methods came from the original "plauclair" version. I removed them entirely from my version as they were unnecessary, and didn't look like they would work anyway, given that trackClicks and trackOpens should be booleans (technically integers, but evaluate as either true or false). I updated chriswthomson/WireMailMailgun last week with fallbacks etc, tested on 2.7.2 and above. Ended up moving straight onto another task and completely forgot to post!
  15. @Macrura - Thanks for the info. I wasn't thinking outwith explicit calls to WireMailMailgun, so that makes sense. I'll probably still add the setSender() and setRegion() functions though, might be useful to have. Cheers, Chris
