Why I should extract three times the infromation from Facebook crawler to get my site information

I have a site made with AngularJS where in order to get the right information from Facebook to share the link, I need to go first to Facebook crawler and extract the information three times before getting the right data.

The first time, I get the default information
The second time I get the title and the description of the specific page, but not the image.
The third time I get the full information (including the image).

But as the site allow the user to upload information and create dinamically new pages, if they try to share the deepling they won’t get all the information at least they go to Facebook scrawler and make it search the page three times…

Im’m using prerender to get the page dinamic information

The page is for example: https://www.granojo.com/video/10403

I just found the problem related about the $scope.isSearching, when we show like above, the ng-click doesn’t trigger. But if i do : <ul class=...

Using PHP and MySQL data to generate PDF letters like in MS Word mailmerge functionality - development

Using PHP and MySQL data to generate PDF letters like in MS Word mailmerge functionality I would really like to know if there is a way like MS Word mailmerge functionality that can be done using PHP and Mysql data. Like i have address data in MySQL (suppose 10 numbers) and through PHP i want to insert that address data in a pre-defined letter head area. And it will automatically generate 10 different letters with same content but different address in PDF. Can it be done? Any start up point will be helpful. As I am working on Laravel so any snippet of that sort will also be useful. Thanks in advance. from Laravel Questions and Answers https://laravelquestions.com/php/using-php-and-mysql-data-to-generate-pdf-letters-like-in-ms-word-mailmerge-functionality/ via Lzo Media

ng-include of inline SVG does not display gradient except in Chrome

I have setup an NG-INCLUDE which loads an SVG file that has classes “hover_color_change” so that the correct polygons can have their fill attribute updated: <div class="prod-illustration-div col s12 m8"> <div class="prod-svg-wrapper" ng-include="'/img/illustrations/illustration_' + productIdObj.illustration + '.svg'" onload="defaultFill(productIdObj.colors)"> </div> </div> I then have color swatches which trigger the $scope.hoverColorText() which calls the updateSVGFill() method to display the SVG fill matching the hover color and creates a shading of gradient so it’s not a solid color. Here is live link – WORKS IN CHROME In Chrome it works, however, in Safari, FF, Edge, it does not. I referenced this suggested answer which suggests referencing the ID attribute, which I believe I am already doing: $scope.defaultFill = function (colors) { if (colors) { var defaultCol...
